Die for hinge parts of CN200 vehicle types

Abstract

The invention discloses a die for hinge parts of CN200 vehicle types, and relates to the technical field of dies for metal stamping parts of vehicles. The die is characterized in that a lower die holder is horizontally arranged at the upper end of a lower support plate of the die via a plurality of lower pads and bolts, an upper clamp plate is horizontally arranged on the upper portion of a stripper plate, and a plurality of upper pads are arranged on the upper portion of an upper die holder; a shoulder screw, nitrogen springs and small guide columns are sequentially arranged at the lower end of the upper die holder and sequentially penetrate an upper base plate and the upper clamp plate to be matched with the stripper plate, guide pins are arranged at the lower end of the upper base plate and are sequentially penetratingly connected with the stripper plate, a lower die plate and a lower base plate, and a lifting block is arranged at a joint of the lower base plate and the middle of the lower die holder. The die has the advantages that operation workers and equipment can be reduced, and a machine can be operated by a single person; the efficiency can be improved by 80%, and the daily productivity can reach 10000 sets; the dimensional tolerance of products can be controlled and is within the range of + / -0.3, and the consistency of the products can reach 98%.

Description

technical field [0001] The invention relates to the technical field of molds for metal stamping parts of automobiles, in particular to a mold for hinge parts of a CN200 model. Background technique [0002] Automobile metal stamping die is an industrial product that shapes materials in a certain way in a specific structural form, and it is also a production tool that can produce parts of industrial products with certain shape and size requirements in batches. As large as airplanes and automobiles, as small as teacups and nails, almost all industrial products must be shaped by molds. The high precision, high consistency, and high productivity of parts produced by molds are unmatched by any other processing methods, and molds determine the quality of products to a large extent. [0003] According to the structure, stamping dies can be divided into three categories: single-engineering dies, composite dies, and continuous dies. The first two types require more manpower and are ...

AI Technical Summary

Problems solved by technology

[0004] 1. Many people are occupied and many machines are occupied: more than 5 people are occupied, and 5 punching machines are occupied, which consumes resources;

[0005] 2. Low production efficiency: only 5,000 sets can be produced per day;

[0006] 3. The product has low precision and poor consistency: the dimensional accuracy of the product is within ±0.5, which is difficult to meet the assembly requirements
