Stamping-resistant automobile die

Abstract

The invention relates to a stamping-resistant automobile die which comprises an upper die base and a lower die base. A concave die is arranged on the upper end surface of the lower die base; a rubberpressure-resistant layer is arranged on the lower end surface of the lower die base; a stripper plate is arranged on the concave die; guide pillars are arranged on four corners of the lower die base;buffer springs sleeve the guide pillars; guide pillar slots are formed in the upper parts of the guide pillars; limiting blocks are arranged at the top ends of the guide pillars; the upper die base isarranged at the top ends of the guide pillar slots; a convex die corresponding to the concave die is arranged on the lower end surface of the upper die base; a fixed pillar is arranged on the upper end surface of the lower die base; and an equilibrium spheroid is movably arranged in the fixed pillar. The stamping-resistant automobile die provided by the invention has the advantages of simple structure, high accuracy, capability of reducing die damage, durability, uniformity in stressing on the die, and high practicability.

Description

technical field [0001] The invention belongs to the technical field of automobile mold systems, and in particular relates to a stamping-resistant automobile mold. Background technique [0002] When people talk about cars, the first thing that appears in front of them is the body of the car, that is to say, the body is the iconic assembly of the car, and the body represents the image characteristics of that car. The general term for dies for stamping parts, that is, "automobile body stamping dies", for example, roof flanging dies, beam reinforcement plate pressing dies, etc. The quality of the die structure and the difference in precision directly affect the quality of the formed workpiece. The die structure Most of them are designed according to the shape of the product. When the current automobile mold is used, the stamping effect is not very good, it is easy to break, and the structure is unstable, which will affect the processing efficiency of the automobile mold.

[0002] When people talk about cars, the first thing that appears in front of them is the body of the car, that is to say, the body is the iconic assembly of the car, and the body represents the image characteristics of that car. The general term for dies for stamping parts, that is, "automobile body stamping dies", for example, roof flanging dies, beam reinforcement plate pressing dies, etc. The quality of the die structure and the difference in precision directly affect the quality of the formed workpiece. The die structure Most of them are designed according to the shape of the product. When the current automobile mold is used, the stamping effect is not very good, it is easy to break, and the structure is unstable, which will affect the processing efficiency of the automobile mold. The mold will use a spring to balance the pressure in order to be evenly stressed, but the spring needs to be sleeved on the stamping rod. Due to the limited stress area of ​​the stamping rod, excessive pressure will cause the punching rod to break, and the effect of pressure resistance is not good. Through the electromagnet plate For the fixing of the lower mold base, the automobile mold must be placed on the bottom of the iron, and the use is limited. If you want the precise and stable work of the automobile mold, you need to ensure the accuracy of the press, and the press with low precision is easy to cause The phenomenon of biting the punch and the die is not very practical. Therefore, it is necessary to provide a stamping-resistant automobile mold with a simple structure, high precision, reduced mold damage, durability, uniform force on the mold, and strong practicability. very necessary
