The characteristics of automobile stamping parts


Print       Small   Middle   Big

The development of stamping parts is more and more closely related to the automobile industry. The manufacturer of punching machine has adjusted the new product development and design philosophy to the direction of the development of automobile industry, and has integrated this trend into their production strategy.

The automobile industry requires to study the technological characteristics of automobile parts and the mutual exchange and development with the automobile industry to develop a flexible production line with modularization and serialization. Flexible production line with car idea crankshaft, connecting rod, cylinder block, cylinder head, camshaft, housing and other hub for the mechanical parts processing, to adapt to the rapid combination modules can be made in mixed flow reorganization of the production line, to grasp the function evaluation, error source, quality control and management integration technology, the development of high speed precision CNC cutting machine, reliable function, at the same time with high-speed feeding, auxiliary equipment such as deburring function, etc.

The stamping parts are divided into cold stamping parts and hot stamping parts. Cold stamping parts are generally no longer machined, or require only a small amount of machining. The precision and surface state of hot stamping parts are lower than that of cold stamping parts, but they are still better than castings and forgings.

The stamping parts are mainly made of metal or non-metal sheet materials with the help of press pressure, and the stamping die is formed by stamping die. It mainly has the following characteristics:

1, the stamping is on the premise of material consumption is not big, created by the stamping, light weight, good stiffness, its parts and sheet metal after plastic deformation, metal internal organizational structure to improve, to improve strength of stamping parts.

2. The stamping parts have high dimensional precision, uniform size and good interchangeability. No further machining is required to meet the general assembly and use requirements.

3, stamping parts in stamping process, due to the surface of the material are not destroyed, therefore, have good surface quality, smooth and beautiful appearance, for the surface paint, electroplating, phosphating and other surface treatment provides a convenient conditions.

In the world automobile stamping die diversification and die replacement cycle short for the representative of the big change, the manufacturers of stamping equipment also found the new world to adapt to their own development. Mould of the diversity that makes auto industry enterprises can produce more types of cars, at the same time puts forward new requirements to the stamping process technology, the chassis stamping technology and the transformation of the produced pieces of car plate processing technology.
