Right mounting bracket blanking and punching composite die

Abstract

The invention provides a right mounting bracket blanking and punching composite die. The right mounting bracket blanking and punching composite die comprises an upper die assembly and a lower die assembly. The upper die assembly comprises an upper die base, a fixing pin, an upper die base plate, a square male die, rubber, a female die splicing block, a stripper plate, stripper screws, stripping rubber, guide sleeves and small round rubber. The upper die base is located on the uppermost portion of the die. The upper die base plate is located below the upper die base. The female die splicing block is located below the upper die base plate. The square male die is located in the upper die base. The fixing pin is located in the square male die. The lower die assembly comprises ejector plates, ejection rubber, a lower die base plate, a lower die base, cushion blocks, a base plate, a male die splicing block, locating pins, guide posts and small cylindrical springs. The base plate is located on the lowermost portion of the die. The cushion blocks are located above the base plate. The lower die base is located above the cushion blocks. The lower die base plate is located above the lower die base. The male die splicing block is located above the lower die base plate. The ejector plates are located beside the male die splicing block. According to the right mounting bracket blanking and punching composite die, a male die and a female die are made into splicing block inverted-mounting structures, so that the die is convenient to replace and maintain.

Description

technical field [0001] The invention relates to a stamping die in the field of mechanical processing, in particular to a blanking and punching composite die for a right mounting bracket. Background technique [0002] The right mounting bracket is the main accessory of the front axle assembly on the chassis of the car. There is a conduit welded on the mounting bracket. The conduit is used to install the rubber bushing and play a buffer role. Therefore, the technical requirements are relatively high. At present, the right mounting bracket It is formed by tailor welding, and then drilled, that is, the two processed plates are assembled and welded first, and processed on a drilling machine. This processing method is inefficient, labor-intensive, and the processing size is easy to exceed tolerance. High-quality products cannot meet customer requirements, and the production cost is too high. Contents of the invention [0003] The object of the present invention is to overcome t...
