"Muscle car " metallic figuration technology

5 pounds, with the Mustang that is about to replace deputy frame photograph is compared, weight reduced 30 ％ ) , wear well and optimal treatment. Besides main stamping workpiece, this component still includes 4 good by supplier punch bracket, 4 pipe that fight crunch solder with 8 nut. Inside the workshop, these component are assembled along a product line, there are 5 robots to solder on product line assemble unit, nut of their protruding solder, means of the bore after using drills two groups of installing hole, be together bracket and crossbeam join, on arc solder, stamping workpiece of lower K component, receive K component repeatedly advocate on crossbeam. Tom Whomsley says " the special place of this component depends on, the punch part that gets one by one to decompose solders them rise, maintain the integrality of dimension at the same time, actually this also is the account that it acquires a success in the market, " he still says, "These components have very close together noncombatant duty -- they are crucial to the treatment of car. The in part that a lot of tolerance buildup compare the common difference that is used on the Mustang car previously is small still, this makes our punch and ship-fitter foreword want to try to change. " " to accord with those close together tolerance buildup, " Whomsley says then, "Stamping workpiece public errand was reduced half, decrease to ± 0.

25 Mm. The conjugate appearance between the clip brim that close check solders and stamping workpiece of form a complete set, make solder thereby consistent, assemble dimension changeless. We do not sell stamping workpiece, sell complete assembly parts however. " the public errand that makes part of large Mustang deputy frame keeps close together, the group of company of this pair of ThyssenKrupp Budd and its labour flying a model supports is a challenge only merely for the group. It still is facing the following challenge, if time tightens the problem with rolled steel quality, have the drawing process that challenges a gender especially, and make a particularly small plank part (easy flap falls in high deferent rate and fly from the mould) achieve the biggest transmit speed. Will perfect K frame to design from the time that begins to although the company was spent,produce 3 months that put in the market nearly 5 years, but the production that it has 3 months only - put the market on time limit, namely the PSW date from May 2004 (the spare parts is referred assure, when all issues that should concern quality and productivity are able to solve) the date that puts in the market to August 2004. Before the PSW date May, it should solve a few when concern with figuration serious problems. To starter part, project team designs K component at first and treatment transmits die spare parts into 7 stations. At the beginning of 2003, the mould engineers of Hopkinsville and Troy think through emulating, spare parts (upside and bottom K component) the shift inside 1500 tons of in the workshop punch in the model can be entered in class. All material of production K frame are 0.

075 inches of thick HSLA steel: Fight Qu Jiang to spend for 51, 000-psi, fight Zhang Jiang to spend for 62, 000-psi. John Mersch of treatment department manager says, "We saved this task to process charge in great quantities, and make crop remarkable increase " . The workshop runs two to transmit punch -- 2700 tons are mixed 3000 tons of Komatsu -- speed of the biggest punch is stroke 15 times / minute. Looked around in November 2004 when us when, class receives a standard with 30 journeys / minute component of speed output K. Mould engineers improve the design that carry takes in the attempt, strive makes this speed minutely again much piece 2 to 3 journeys. "From the biggest challenge that transmits punch to become successive punch place to be faced with it is of the belt decorate and carry clip the slashing public errand on line and hole and but repeatability, " Mersch says, " because such, so we just are assembling the to this frame component important link on component to nod the stiletto after undertaking. " we are in the mould is indoor saw die, mould workers are added here add strong stalk in order to solve problem of slight spring back, make afresh take guider to be in in order to help a spare parts keep stable between punch every time, still can make journey rate increases. Class works two hours to be able to be equivalent to the product stocks of Ford company a week to extrude inside punch workshop into the model. The workshop already improved fast die to change working procedure, make last makings falls to the first makings thereby next spends average time achieve 20 minutes. The drawing beam stamping workpiece that transmits a medium difficulty is in 8 stations die in the workshop transmit the shift inside punch. According to Introduction Merch, these spare partses need deep punch, this are the most distinctive design characteristic, because this gives the take shape of the spare parts,created the most difficult challenge. Merch says, "This kind of drawing is designed, and develop it all round outside outline, start functional installation in order to make to be in that place to appear crucial to obtaining needed tigidity. So that design mould makes stamping workpiece with a makings, this one task has quite big challenge sex, because this is planted,high strenth alloy is met during figuration remarkable sclerosis. We must take care, cannot be inside certain area excessive treatment it, and lest deep punch occurrence craze is mixed,should undertake many emulation add thick phenomenon. " undertake emulation on the PAM-Stamp software that the ThyssenKrupp Budd engineers that are located in Troy provide in company of group of French supplier ESI. Explanation of mould engineer Shaunee Underwood says, "To finish this kind of drawing, we must reconsider beforehand figuration process, in order to achieve necessary circuit length, lest be in,station of the last drawing appears excessive drawing, prevent to tear off. We do not undertake by the direction of drawing beforehand figuration, and adopt raised beforehand figuration, place compares us with deflection at first according to cave when means will emulate a station, ever was out of shape with what pass should small. PAM-Stamp makes we can material beforehand figuration is decreased the smallest, and still achieve a needed circuit length. " after undertaking final stretch to raised part, die station clipping gives a square opening, make the spare parts has flange. Underwood says palpability is in 15 times the journey / minute the 2nd challenge that makes crossbeam figuration place is faced with below speed, "Wants rate to us character is to hit ' swat ' , and it is only not just ' homer ' (speed is the journey 12 times / minute) . This part is very small, easy when transmit flap. We and the supplier that transmit a system -- Syron project and production company (Saline MI) a cooperation, observe us carefully pass a window, transmit in order to ensure the structure of die won't be cloggy. Had constructed to transmit when Syron after pointing to, its engineers install a mould together with us, so that use optimal way to locate,transmit point to, reduce flap lowermost rate thereby. Our speed remains the journey 12 times / minute, and we hope to achieve the distance 15 times / minute speed. " when high speed is transmitted, stamping workpiece flies easily from the mould, this one problem makes before mould engineers return drawing board, they offerred a kind of solution: Use pneumatic elevator bolt of nitrogen of compose and rather than. Mersch explanation says, "Through using double-barreled pneumatic elevator compose, we can control the part that come up. We dial elevator compose move 180 go to 185 degrees, come so the part follows with the least shift pressure head rises. This makes the spare parts keeps stable, enough makes us acquire 3 additional routes / minute. " need to satisfy production, transmit punch to be used every week 1.

5 to 2 Mustang die, and solder assembly line runs two everyday. Rolled steel problem even if the design that arranges best and manufacturing plan make mistake possibly also, produced such situation fitly in March 2004, say according to Merch, the workshop begins problem of quality of occurrence rolled steel in those days. "The quality of rolled steel and supply a problem we were hit when the move is really impertinent, " he says, "When considering the complexity of drawing for crossbeam stamping workpiece. We once made certain part, did not appear 3 years the problem of craze, appear suddenly however in those days in whole area craze phenomenon, caused disastrous effect to stamping workpiece. To K shop assembly, we ask N is worth for 0.

13, stretchy 25% , in order to avoid craze. We and clasp of rolled steel supplier in order to ensure rolled steel quality. " " the clip position that we still changed die to go up in order to avoid successive cutting, " Underwood complement says, "Although have the gap of an iota that causes by successive cutting only,we discover drawing flange, also can bring about rolled steel craze. Once, we discover the preform box that transmits punch to go up even rolled steel rift. We must move guide bar will solve this one problem. " besides redesign create a few patterns, and open the athletic window with an a bit wider in a way besides, the settlement with workshop best discovery method is a kind of new mould finishing working procedure, it lube use up reduce least. The workshop still installed a central lubricant system to come to those who optimize lube to carry. "We are bought now condense model lube, mix it and water here, " project manager Kurt Spencer says. "We use cubage pump to allocate mixture through a system that raise a canal. Conduit crosses base, enter punch up, this makes we can need lubricant place neatly to place the lube with metric classics accurately on stamping workpiece. " in the supply that cut down fundamental go to work makes ThyssenKrupp Budd ground the usability of its punch baseplate and window dimension and punch time, the decision contracts stamping workpiece to other producer. "In 10 years of in the past, " Whomsley says, "We had made very great effort come to those who reduce us supply a base. We ever sought the supplier that can offer overall service to support. This makes we cooperate with lesser punch business no longer, turn and connection is more and medium-sized, different factory. Nowadays, we obtain stamping workpiece from nearly 12 factories, their all passes quality system 9000 attestation. Of course, want to offer stamping workpiece for Ford company, the supplier must have Q1 letter. " " the supplier of future of our evaluation of central purchase department, " Whomsle says then, "Be in when us in the workshop when general affairs of processing rear services, our Troy headquarters is undertaking quote and be buyinged. We are satisfied to the amount of stamping workpiece supplier of collaboration, and we because this is relaxed a lot of. And we because this is relaxed a lot of.. CNC Milling CNC Machining
