Description

Technical Field

[0001] The utility model relates to the technical field of disc spring production, in particular to a stamping die for producing disc springs. Background Art

[0002] Disc spring, also known as disc spring, is a special spring that is conical in the axial direction and bears load. After being deformed under load, it stores a certain amount of potential energy. When the bolt is loose, the disc spring releases part of the potential energy to maintain the pressure between the flange connection to meet the sealing requirements. The stress distribution of the disc spring decreases evenly from the inside to the outside, which can achieve the effect of low stroke and high compensation force.

[0003] In the process of disc spring production and processing, a stamping die is often used to form the disc spring. During the use of the existing stamping die, the upper die and the lower die in the stamping die are often directly mounted on the punch press by bolts for use. When the upper die and the lower die need to be replaced, it is necessary to use tools to remove all the bolts before the upper die and the lower die can be replaced. After the replacement is completed, it is necessary to use tools to install all the bolts back, which makes the whole process more troublesome to operate, and a lot of time required for replacing the upper die and the lower die will be wasted, thereby reducing the production speed of the disc spring. Therefore, the utility model provides a stamping die for producing disc springs. Utility Model Content
