Punching mold for car bracket

Abstract

The invention relates to a punching and forming die of an automobile support. A screw rod is fixed on a knockout rod, a knockout pin is fixed at the lower end of the screw rod, an upper subplate is fixed on the lower surface of an upper die plate, an upper fixing plate, a concave die, a positioning column and a retaining plate are fixed on the lower surface of the upper subplate, the concave die, the positioning column and the retaining plate are positioned in the fixing plate, a lower fixing plate and a vertical plate are fixed on the upper surface of a lower die plate, the vertical plate is positioned in the lower fixing plate, a lower subplate and a punch fixing plate are fixed on one side wall of the vertical plate, an ejection plate is mounted on the punch fixing plate which is positioned on the lower subplate, an ejector block is slidably connected in the lower fixing plate vertically, a supporting spring is arranged below the ejection block, and the upper surface of the ejection block is a bevel. When the punching and forming die is in actual use, product accuracy and finished product ratio can be greatly improved, energy resources are saved, and waste of materials and the energy resources is avoided; the punching and forming die is simple and reasonable in structure and convenient to operate.

Description

technical field [0001] The invention relates to a punching and forming die, in particular to a punching and forming die for an automobile bracket. Background technique [0002] At present, SAIC-GM's A8827306 car bracket consists of four parts: side bracket, left bracket, right bracket and cylinder. Generally, the following steps are used for production: first punch holes on the cylinder body, and then weld the punched cylinder body with the side bracket, the left bracket and the right bracket. The A8827306 automobile bracket produced by this method has poor precision and low yield, and the welding process is easy to deform the punched hole and cause the overall scrap. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, and to provide a punching and forming die for automobile brackets with high product precision, greatly improved yield and convenient operation. [0004] According to the technical solutio...
