Problems solved by technology

As far as punching is concerned, due to the irregularity of the car cover, it is impossible to directly process the holes on the car cover vertically, making it more difficult to process. At present, the car cover is also processed with a diagonal wedge structure. , but the current processing method has the following deficiencies: 1) The force point and the force point are transmitted through a bridge, which is far apart and the force is poor; 2) The structure is a non-standard part, the production cycle is long and the cost is high; 3) The structure Complexity, increased mold size and increased cost

Abstract

The invention discloses a punching technology for inner sidewalls of parts of an automobile covering component. The punching technology is characterized by comprising the following steps of: assembling dies, lapping in the dies, mounting a material pressing plate, mounting a blank, punching, and taking out the part, wherein in the step of taking out the part, an upper die 1 and a lower die 2 as well as an inclined wedge mechanism 3 are reset to take down a workpiece. By virtue of the punching technology, the processing precision of punching can be improved to a great extent, and the production efficiency of punching can be greatly improved. The dies adopted by the punching technology have the characteristics of being simple, novel and compact in structure, easy to realize, etc.

Description

technical field [0001] The invention belongs to the technical field of automobile parts production, and in particular relates to a punching process for the inner wall of an automobile cover part. Background technique [0002] Automobile panels refer to auto parts that make up the car body or cab, the surface and interior of special-shaped bodies that cover the engine and chassis. Automobile panels are mostly two-dimensional surfaces with large size and complex shape, which cannot be expressed by simple mathematical analysis. It not only requires high appearance quality to meet the requirements of automobile styling, but also requires high matching precision and consistency in shape and size Good and high interchangeability requirements to ensure its welding and assembly quality. Therefore, the stamping equipment, molds and raw materials used in the production of automotive panels are different from those of general stamping parts production. The stamping forming technology...
