Cold Forming to Net Sigma Shape

$15.00

A continuous scrapless process for forming a wing shaped automotive component used on starter motors from solid diameter wire to a net shape meeting Sigma requirements.Process and production equipment consist of coil stock stand, prestraightening unit, sizing unit, 1500 ton mechanical press. With forming tooling and counter-pressure unit for fine shearing. The major stages of the shaping of the part shown on Sketch 44-2090 are:1. Size diameter for precise volume control.2. Flatten sides.3. Preshape to a ‘T’ shape.4. ‘T’ shape.5. Transition ‘T: To wing ‘U’ shape.6. Wing ‘U’ shape.7. Transition wing ‘U’ to coin shape.8. Coin
