Problems solved by technology

However, since the lower mold in the mold is a fine part, a small error can cause the machine parts after punching to become defective products
Moreover, for the car bracket with many through holes, if it is formed at one time, it is very easy to cause deformation of other parts of the material plate, resulting in defective products, lower pass rate, increased cost, and affect production efficiency

Abstract

The invention provides a lower die structure of an automobile bracket continuous punching die. The lower die structure comprises a lower die holder and a bearing plate. A conveying mechanism is arranged at one end of the lower die holder and comprises a feeding plate, rotary feeding rollers and conveying positioning blocks, wherein the feeding plate is located at one end of a short edge of the lower die holder, and the rotary feeding rollers are located at the two sides of the feeding plate and driven by stepping motors; a plurality of positioning holes arranged at equal intervals are formed in the center of the bearing plate in the conveying direction, a plurality of special-shaped groove seats are arranged at the two sides of the positioning holes in the conveying direction, each special-shaped groove seat is provided with a special-shaped groove, and the conveying positioning blocks are mounted on the bearing plate and located outside the special-shaped groove seats. The lower die structure of the automobile bracket continuous punching die has a pipelined punching function, punching precision is high, product quality is good, and production efficiency can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of automobile bracket molds, in particular to a lower mold structure of an automobile bracket continuous punching mold. Background technique [0002] Car brackets, as one of the important accessories of cars, have been more and more widely used. There are usually various through holes on the car bracket, including round holes, square holes or special-shaped holes, etc., for fixing or heat dissipation. These through holes on the car bracket are completed by the punching device on the mold. However, since the lower mold in the mold is a fine part, a small error can cause the machine part after punching to become a defective product. Moreover, for the automobile bracket with many through holes, if it is molded at one time, it is very easy to cause deformation of other parts of the material plate, resulting in the production of defective products, lower pass rate, increased cost, and affect production efficienc...
