|
The spring-back of 3042B stainless steel is bigger and difficult to control the forming precision.The process scheme of the stamping die for the stainless steel clip of adhesive tape under the fan of the indoor unit on air-conditioner was designed,the blank layout and the structure of the stamping die were designed;the problem of the spring-back was successfully solved during the process of the stamping die for the stainless steel clip.The process scheme with 13 positions at one progressive die contained many working procedures,such as punch,press edges,bend and sizing.The die has been applied in mass production,and the forming precision can be controlled inside 0.1 mm.The annual output of 1,000,000 pieces was easily carried out with the progressive die.
