Problems solved by technology

[0002] Existing blanking and stretching composite molds are mainly composed of upper mold base, lower mold base, guide pillar, guide sleeve, convex and concave dies, mold handles, deep drawing punches and blanking dies. The mold cannot realize automatic ejection, and the workpiece needs to be pushed out manually, which is not only time-consuming and labor-intensive, but also leads to high production costs

Abstract

The invention discloses a blanking and stretching composite die capable of automatically pushing a workpieces. The blanking and stretching composite die capable of automatically pushing the workpieces comprises an upper die base, a lower die base, a guide column, a guide sleeve, a punch die, a cavity die, a die handle, a stretching punch die and a blanking cavity die. The blanking and stretching composite die capable of automatically pushing the workpieces is characterized in that a workpieces pushing block is mounted in a cavity of the punch die and arranged just facing the stretching punch die, a hitting rod is mounted at the top of the workpieces pushing block, one end of the hitting rod is fixed to the top of the workpieces pushing block, and the other end of the hitting rod penetrate through the die handle to extend upwards. The blanking and stretching composite die capable of automatically pushing the workpieces can automatically eject the workpiece to push out the workpiece after the stretching forming of the workpiece is completed, is high in automation degree and is mainly used as a stamping die.

Description

technical field [0001] The invention relates to the technical field of moulds, in particular to a blanking and stretching composite film that can automatically push parts. Background technique [0002] Existing blanking and stretching composite molds are mainly composed of upper mold base, lower mold base, guide pillar, guide sleeve, convex and concave dies, mold handles, deep drawing punches and blanking dies. The mold cannot realize automatic ejection, and the workpiece needs to be pushed out manually, which is not only time-consuming and labor-intensive, but also leads to high production costs. Therefore, it is very necessary to design a blanking drawing composite mold that can well solve the above problems. Contents of the invention [0003] The purpose of the present invention is to improve the deficiencies of the prior art and provide a blanking stretched composite film that can automatically push parts. [0004] The specific solution of the present invention is to...
