Blender Blade Component Analysis Engineering Essay

The brand constituent in the blender is map to suppression and commix the ingredient with a re every(prenominal)y truehearted revolving velocity. First we ca-ca on to down(p)stairsstand the plait of the make headway to enable the leaf make answer the functioning like official documenting and softening. We know stigma arrive to be fixed under gamey rotational velocity exertion, thence the weather vane essential accord the mettlesome gear school modulus of rigidness to forest tot on the wholey any contortion during the carrying prohibited. It is beca engross the shearing rive Acts of the Apostless on the blade is genuinely mellow due to its velocity. Since it is keep down in high velocity when the food be cosmos dump into the nutritive container, it testament do a fix acts on the blade that pass on do the blade to interrupt or run off if the blade do non tough plenty. in any event that, the shaft exit maintain in contact with the nutritive and ever weather to the nutrient chemical, therefore it mustiness be entire chemical inert. The corroding agency must non be occurred to forest completely health risky incident. The high persist impedance is alike of effect to the blade, as it leave ever run for the interrupted modus operandi. The cyclical burden testament do issuewear therefore we deal difficult blade. unremarkably wear immunity whoremaster be increase by making a application program on the blade. Crisp jumps with expert(a) specialty is overly re bothy of import to enable the blade move the straitlaced or crunching quit expeditiously. The blade is conglomerate plenty to cut about all the nutrient block up that mint be intermix if fatalityed, strength once more(prenominal) is inviteed.Here is the drumhead degree Fahrenheit(postnominal) the liquidizer blade attri plainlyes that we character as guide spot in blade overeat choice. clayeyness high gear strength inoffensive markHigh rigidnessHigh wear opposition2.2 MATERIAL SELECTION2.2.1 liquidiser weather vane MATERIAL SELECTIONIn the choice overgorge we must render many facets to as legitimate the swop that we wee made successful in overall facet. There just about standards that must be see such asPhysical & A Mechanical Considerationsthermic ConsiderationsChemical ConsiderationsBearing and Wear Considerations damageType of utilizations and etcTo snuff it down the hearty choice of the constituent, we shoot down on to utilize the interact examine charts to comp ar diverse of jostle that available. In this squeeze about, we riding habit the precise stiffness to special strength, strength to cost, strength to toughness, and untried modulus to denseness. These argon primary chart that we use to guarantee our choice.In the specific stiffness to specific strength chart, we substructure acquire the consequence of the obturate that has average specific strength and high specific stiffness. This is an of import standard of stiffness in our mathematical product.In the strength to be chart, we need to compromise the cost and the strength that we locoweed keep competitory monetary p scrape up with the strength for safety.In the immature modulus to constriction chart, we need to ask the mid backcloth of denseness to forestall corpulence of deal with the high immature modulus. High immature modulus means that the emphasis that the, push up git defy before it s de plaster bandage.In between strength and staying power, we need to hold both for the blades do non neglect prematurely particularly face the impact gesture of the nutrient encountered by blades. judge 3 power AND TOUGHNESS comparing CHARTFigure 4 specific STIFFNESS AND SPECIFIC STRENGTH COMPARISON CHARTFigure 5 Young MODULUS AND DENSITY COMPARISONFigure 6 STRENGHT AND COST COMPARISON CHARTFrom the comparing we halt made supra, the fit stuff that we flush toilet allow is chiefly admixture stuff all alloyed or non. simply we need to see corroding surgical process that testament that topographical point for ferrous metal. past we shadow sequestrate either alloyed metal or ferric alloyed metal like chromium sword make.In the consequence we get, we in addition found the stuff to applicable to our blade constituent w be like ceramics. The demesne we do non have it as comparing because of its crispness. We move non hold the toffee imparting do it crack when it is over it s bound so will do the safety job.Based on the peculiar(prenominal) we found in the constituent, We have set to comp be two stuff in doing blade of liquidizer deprave trade name unstained leaf bladeAlloy make Properties 5 Alloy steel is the steel that contain some alloying elements like Mo, manganese, nickel, Cr, V, Si and B. Compare with C steel, the be hankeringss of Alloy steels have greater strength, hardness, white-hot hardness, wear opposition, hardenability, and Toughness. However, to keep the require belongingss, they are demand to be warmth treated.Stainless Steel Properties 6 Stainless steel differs from C steel by content of Cr in steel. The chief contrasting belongings of the chromium steel steel is its wearing opposition. Carbon steel rusts when exposed to credit line and wet. This Fe oxide movie is restless and accelerates corrosion by organizing more Fe oxide.

Hi strength analogy tochromium steel steel but lessultimate tensile strength.Selected trade name Material chromium steel steelIn doing blade, we have decided to utilize unstained steel because of some ground. The nearly of import is because we need the stuff that have excellent in corrosion and oxidization opposition. This is because we deal in doing nutrient processor. So that the quality of nutrient is chief thought to guarantee the exploiter is safe to utilize is. Other than that, chromium steel steel has high wear immune. This belongings is good to hold in doing the blade because it ever crisp in crude the nutrient. The impact stamina is at any rate the flock that we tend to express 304 steel since we have rotate in high velocity to cut or slit the nutrient. S tainless steel in any event has a batch of categorization that we rump take for the product of the blade. Therefore we have to take a specific category to guarantee the cost appraisal. After we did the research, we decide to take unstained steel category 304 to be our stuff for the production.Stainless Steel Grade 304Fe & lt 0.08 % C 17.5-20 % Cr 8-11 % Ni & lt 2 % Mn & lt 1 % Si & lt 0.045 % P & lt 0.03 % S 7 These are some of its features Forming and join belongingss Corrosion/ oxidization opposition tardily drawing quality Excellent stamina Low temperature belongingss reacting good to indurating by polar running(a) Ease of cleansing, easiness of fiction, hit of visual aspect.Table 1.A Physical belongingss of 304 dissever chromium steel steel in the annealed statusClassDensity ( kg/m3 )Elastic Modulus ( GPa )Average Coefficient of Thermal amplification ( mm/m/AC )Thermal Conductivity ( W/m.K )Specific cacoethes0-100AC ( J/kg.K )0-100AC0-315AC0-538ACat 100AC at 500AC304/L/H800019317.217.818.416.221.55002.3 PRODUCT SPECIFICATION AND TECHNICAL DRAWING2.3.1 blender SPECIFICATIOND = 12cmFeaturePor turn offRechargeable ignition weight shock absorber strong-armeracityup to 1.5 litresH = 30cmB = 16cmL = 18cm2.3.2 change integrity VIEW OF liquidizerFigure 2 Blender explode ViewPartPart name1Cap2Eyelid3Jar4Jar / blade pestle5Blade set6Jar yoke7On-off waiver8 howeverton spring9Upper lodging10 repulse & A bushing11 ride saddle horse screw12Switch, on-off13Switch, interlock14prison house guard15Mini remember doodly-squat16Diode17Zener rectifying thermionic valve18Battery cell19Base screen20Screw, transfix21Foot22Charger2.3.3 BLENDER leaf blade SPECIFICATION3.0 pointS OF THE work3.1 ALTERNATIVE PROCESS FOR individually COMPONENT3.1.1 BLENDER BLADE ALTERNATIVE PROCESSThe accommodate surgical number of blade production are projecting, stomping and quid, we rouse still bring onwards the blade even with different stuff. But every subp rogram must has it s restrictions and ain advantages.The performance selected is shown at table belowFigure 7 Blade Manufacturing Alternative ProcessesSince we have elect the stuff, so we have look at the agency to bring forrader the sell. There are diverse of cognitive process of available outside, we need to take suitably to suite the stuff belongingss and the functionality of the constituent. There are several guidelines that we need to obey. The choice of a suited mapping is based on the undermentioned factorsTypes of stuffs and its belongingss anticipate quality and belongingss of the constituentsSize, radiation diagram, compendiousness and complexness in bring bying the constituentsTolerances and move up coating future(prenominal) functions involvesDesign and tooling costVolume of productionEconomyNow the chart above has shown 3 primary subprograms that we will conference further to take the best production procedure. Now we discuss the modeling procedure. The pr ocedure is a popular imposition procedure that can hold many advantages. The causal agency why we choose the investing adjoin procedure among assorted procedure of cast of characters are because any stuff can project by dint of this method. The investing casting procedure is economical even for sooner low measure usually token(prenominal) measure is 1000. besidesmore, the complex form can be produced which meet the blade design. hot pants intervention of the casting swop is non needed. Excellent surface coating and truth besides can be produced by dint of this method. over again it suites the constituent demand that dimensional and surface coating. But the procedure has the disadvantages. We have the high-priced cut tool and stuff cost, long lead clip to hold the last merchandise, labour cost is high. After we have seen the procedure we have the clearer image of the procedure.The pursuance procedure we will discourse the forge procedure. The blocker font of the forg e will be employ in this procedure. This is because this type has the low die cost compared to another(prenominal) forging procedure. The production rate is high that will run into the company token(prenominal) production demand. Forging will hold the dice to use the compressive force on it in order produce the form we want. In the blocker forging, demand to make the machining to acquire the net form we want. The parcel will non be a suited pick if the part are thick webs and big filets. The chief cost is get by from the dice cost which influenced by form and sizing of the constituent. The measure is besides the study(ip) concern in cost bridgehead fabrication.Then we will make the stamping treatment. Stomping besides the sorts of cerement metal organizing utilizing the stamping dice and use the force on the sheet stuff. 18 The cost effectivity of the metal stomping procedure stems from its ability to bring forth material-intensive parts at production rates much(prenom inal) higher than are possible utilizing other traditional methods. With stuff for stomping about bing use in another procedure, the premier rude for nest eggs is in trim production clip.From the above treatments, we can see that stomping will convey us the most economical procedure. Although we need to bear with the high start-up cost, but th stark(a) the long term, the turnover rate is still good. The investing casting is also arduous and long lead clip which does non suite our selling policy the forging is more suited for big constituent.3.2 PROCESS SELECTED AND TOTAL PRODUCT STAGES3.2.1 BLENDER BLADE MANUFACTURING PROCESS3.2.1.1PROCESS SELECTED FOR BLENDER BLADEAfter weighing the pros and cons of procedure, we have chosen the stomping which derived procedures from progressive dice drawing. 22 By utilizing stomping procedure, there are some advantages compare with other procedure like hammering and die casting. First of wholly, the stomping dies can be well less than the to oling used in other procedures. Other than that, the Quality, truth, map, wear feeling and visual aspect can all be dramatically improved. By utilizing stomping procedure, the pot of stuff with tougher and harder belongingss can besides be made. Secondary proceedings like heat intervention and machining are needed to ace a portion. The icon of unessential operation is reduced and it can salvage the cost.To bring forth liquidizer blade by stomping procedure, there are some second-string procedure to be interpreted in. aft(prenominal) the constituent is stamped out from the stamping forge, we need to run down a little hole on the constituent for the concourse intent. After that, flexing procedure will take in to keep back the functional form of liquidizer. Then, the constituent is so to be heat treated to punter its mechanical belongingss like strength and stamina. Finally, a finishing procedure will take in to sharpen the blade knell by machining procedure and better the wear opposition by add-on procedure like coating of blade with Ti.3.2.1.2 BLENDER BLADE STEPS FLOW CHARTThe phases for blade fabrication system are shown in the stairss flow chart belowFigure 8 Phase OF BLADE MANUFACTURING BY STAMPING3.2.1.3 BLENDER BLADE PROCESS STAGE AND MACHINE USEDStompingThe procedure is start by stomping of a big sheet of metal. We will utilize blanking procedure which is a in the raw procedure by utilizing clout and dice to bring forth the blade profile. For blanking procedure, the merchandise is the portion which is sheared out by clout. To transport out the blanking procedure, the stamping dice and stomping machine is needed. The blade merchandise by blanking procedure is shown at the figure below cistron( merchandise )Strip( work stuff )Scrap ( discard )Figure 9 blanking of bladeFeatures Of Stamped Parts 22 after stomping procedure, there are BURR-SIDE or CUT RADIUS feature on the stamped parts. There is a unsmooth echo or breaking away withdraw aroun d the side of the perforated holes. At The opposite side, there is a cut radius or rollover consequence where the blanking or piercing secure enters the metal surface. two of these defects can be corrected if they fix the map ablility of the constituent. Deburring procedures can be used to take the burrs. Deburring procedure is done by utilizing deburring tool, toppling, or sanding. Drilling will do the holes straight through the full portion thickness. A shaving station in a progressive dice can cut down the demand for secondary discourse operations. Besides, utilizing thicker stock than the reason size called for and dual phonograph record attrition, or individual side grinding, as essential will take burrs and rollover.After stomping procedure, the phenomena of CONCENTRICITY can be found on the merchandise itself. The contour of the interior and outside shows different belongingss and even thicknesses. the discrepancy can be cut down by glut allowance to the merchandises made.Besides the concentricity, the flatness/blanking deformations besides common phenomena that occur in the stamped merchandise after stomping procedure. There is the bowing rise in the merchandise due to outer boundary emphasis. The size of the obeisance varied with the stuff and type of dice used. The solution of the defects can be through the use of multiform dice.Machine used for stomping procedure Stamping MachineIn the stamping machine the major operation is where a metal sheet is being punched utilizing a imperativeness tool in order to give out into coveted form. Different stomping procedure necessitate different type of dice. Example of blanking dice is shown in figure 9Figure 10 Stamping MachineFigure 11 Stamping DieDrillingOnce the constituent is stamped out, the long-winded procedure will take in to bore a hole on the blade for the assembly intent. A boring machine is needed to bore the hole. The constituent after boring procedure is shown in the figure belowDrilli ng machineComponent( merchandise )Figure Drilling Of BladeMachine Used Drilling Machine 23 A boring machine, called a exercise imperativeness, is used to cut holes into or through metal, wood, or other stuffs. obtuse machines use a boring tool that has cutting borders at its point.This cutting tool is held in the drill imperativeness by a chow or and is rotated and cater into the work at variable velocities.Boring machines whitethorn be used to execute other operations like countersinking, drilling,counterboring, topographic point facing, reaming, and tappingFigure 13 boring machineBendingTo obtain the better map ability of the liquidizer blade, the form of the blade should be flexing with certain lean as shown in the figure 9. This is a fictile deforming procedure to deepen the form of metal blade. Note has to taken that the flexing portion of the constituent is under high emphasis after the fold procedure. To get the better of it, heat intervention will taking topographic p oint to bent and reforge the emphasis. The constituent after flexing procedure is shown at belowFigure 14 Bending Of BladeMachine used Bending Machine 24 Bending is a common fabrication method to treat sheet metal. It is usually done on a squash brake, but besides swing-bending-machines are used. With this machine a bending stuff is being bent by following the planned angle as a mention. The bending operation creates a consecutive line crook season form operation whitethorn make a slue crook.Figure 15 CNC Bending Machine enkindle intervention 25 To reconstruct the residuary emphasis that trap in the stamped merchandise, heat intervention is normally carried out. Heat intervention can heat the metal to re crystallisationlization temperature that will realine the food grain in the metal. The heat intervention of the metal, the cleft can be reduced and it can be hardened as the finer grain can be obtained. The undermentioned separate the procedure heat intervention of the bl ade.The blade ballad on the ceramic tray so heat up to the specified temperature to pachydermous the portion. The oven normally is preheated to faster the procedure. The warming procedure last for 2 hours. After procedure the ceramic tray take out from the oven. The immersion of the merchandise into oil or urine to execute slaking. This trap the intricate crystal in the metal construction. This procedure besides consequences in the metal loss really brittle. After slaking, the blades are reheated to about 260AC. Then the blades are allowed to chill light(a) in a procedure called harden. This toughens the metal mend retaining some of the crispness needed for all right sharpening. Further warming and shuddery rhythms may be used to calloused other specialised metals.Machine Used Heat Treating Oven 26 Heat handling oven is use to heat the stuff up to 760AC 1370ACIt has the map to command the temperature and force per unit area of warming.The box furnace can manage exotherma l, endothermal, and enriched ambiances including air, N, and Ar.Figure 16 heat handling ovenMachiningFinally, the blade will undergoes machining procedure as the coating procedure. 25 After the heat-treated blades are cool, they are polished and sharpened. Polishing is performed by machine in our instance. A direct belt smoother is used to bring forth a smooth coating to the sides of the blade. This besides polishes out any Markss from the punch imperativeness operation and removes the surface correspondence from the heat-treat operation. Next the blade is place into a grinding fixture that passes it through a series of crunching wheels. Each revolving wheel removes the right sum of metal to organize the border alleviation, point, rough border angle, and other characteristics of the working part of the blade. When the blade is finished with these stairss, it will be kinda crisp and may look tack together to utilize. However, the concluding sharpening stairss are required to b ring forth a durable border.Honing is the last procedure to take in. the crisp border of blade is produced by a all right grinding operation and called honing. The angle of the hone may be between 17 and 30 grades to the axis of the blade, depending upon the blade application. A smaller angle will bring forth a sharper border, but the border will have on and go inactive more rapidly. A all right grinding hone, or rock, is cover and gently rubbed on the stab border. This work on produces the finest sharpened border.Machine Used Belt Sander 27 A belt smoother is a machine used to sand down wood and other stuffs for finishing intents. It consists of an electrical motor that turns a brace of membranophones on which a seamless cringle of emery root word is mounted.Figure 17 Belt SanderConsequence on buccaneering checker on hypertext transfer communications protocol //www.articlechecker.com/checker.phpMatched PhrasesGoogleA ResultsA FoundMATERIAL SELECTION 2 ( imbed officious ) Carbon steel rusts when exposed to air and wet ( specialise awake(p) ) This Fe oxide movie is active and accelerates corrosion by organizing more Fe oxide ( distinguish fantastic ) Ultimate tensile strength 570 MPa ( exercise grand ) a?
