Split type die sleeve for straight die shank

Abstract

The invention relates to a split type die sleeve for a straight die shank. The split type die sleeve for the straight die shank comprises a first die sleeve and a second die sleeve which are of a split structure, the section of the first die sleeve and the second die sleeve are of an arc structure, the radius r1 of the first die sleeve is equal to the radius r2 of the second die sleeve, the radian a of the first die sleeve is equal to the radian b of the second die sleeve, the two lateral surfaces of the first die sleeve are a first contact surface and a first gap surface respectively, the two lateral surfaces of the second die sleeve are a second contact surface and a second gap surface respectively, the first contact surface and the second contact surface are arranged in parallel, and the first contact surface of the first die sleeve and the second contact surface of the second die sleeve are matched to form a non-closed ring overall. The split type die sleeve for the straight die shank is simple in structure, is directly arranged on the die shank in a sleeving mode, is high in universality, prolongs the service life and saves the cost.

Description

technical field [0001] The invention relates to the field of stamping die parts, in particular to a split die sleeve for a straight die handle. Background technique [0002] The stamping process is an advanced processing method with high production efficiency, less cutting or no cutting. It has many advantages in economy and technology. It is easy to operate, easy to realize mechanization and automation, and is suitable for the production of large batches of parts. , its products generally do not require further machining, and their dimensional accuracy and interchangeability are relatively good. Therefore, it occupies a very important position in industries such as aviation, automobiles, tractors, electrical appliances, and precision instruments. In stamping production, stamping dies, as specific execution tools for stamping processes, naturally receive much attention. The design level and manufacturing precision of the structure are the key to ensure the quality of stampi...

AI Technical Summary

Problems solved by technology

[0003] Because there are many types of small punches, the size of the mounting hole of the punch slider mold is different, and there are many models of the thickness of the mold handle, the molds cannot be interchanged between punches, and the versatility is poor. Sometimes it is necessary to reserve multiple mold handles and use the method of replacing the mold handle to complete the use, which is not convenient for production

[0004] In the production of small stamping parts, the mold is restricted by the size of the slider hole and often requires the use of a fixed punch. If the mold is used and the matched punch is damaged or there is no suitable punch resource, the work will be passive or the construction period will be delayed.
