U-shaped ring punching die

Abstract

The invention discloses a U-shaped ring punching die. The U-shaped ring punching die comprises a punching upper die base and a punching lower die base which are in sliding connection through a punching guiding shaft. The bottom of the punching upper die base is provided with two forming punches. The positions, corresponding to the forming punches, of the surface of the punching lower die base areprovided with forming punching bases provided with forming holes. Penetrating material falling holes are formed in the bottoms of the forming holes. The two ends are machined at the same time, the diecan conduct punching and edge cutting at the same time, the accuracy of the relative size is protected, and errors caused by two-time machining are avoided. The machining process is simpler while thesize and the quality are guaranteed.

Description

Technical field [0001] The invention relates to the technical field of power transmission and distribution equipment, in particular to a U-shaped ring punching die. Background technique [0002] U-shaped hanging ring, which is used in the market and consumes tens of millions of tons across the country, is a product that needs to be mass-produced. Due to high strength requirements and high internal crystal phase organization requirements, it involves material mechanics, mechanical manufacturing, forging processes, and stamping processes. Every change in production practice has to go through a lot of actual operations to prove its correctness. The traditional processing technology is: firstly, round steel is made into dumbbell-shaped ingredients, and then processed according to the following procedures: single-end heating → forming → trimming → punching → heating at the other end → forming → trimming → punching → heating → Curved type, so the existing technology needs to be heated...

AI Technical Summary

Problems solved by technology

The traditional processing technology is: firstly, the round steel should be made into dumbbell-shaped ingredients, and then processed according to the following procedures: heating at one end → forming → edge trimming → punching → heating at the other end → forming → edge trimming → punching → heating → Bending type, so the existing technology needs to be heated many times, and both sides are processed separately, the center distance cannot guarantee the error of 5-10 mm, and the process needs more than 10 processes to complete, and labor, equipment, and time are used a lot, resulting in production costs High, unstable quality
