Description

Technical Field

[0001] The invention particularly relates to a butterfly washer die and a punching system. Background Art

[0002] Belleville washers, also known as spring washers, are designed to prevent loosening of bolts and screws. They are usually used for the connection of medium or high-strength bolts and screws. Belleville washers work by using the tension generated by the rebound of the product after being stressed to prevent loosening and slipping. When the gasket is installed and flattened, it can ensure that the stress distribution on the tightened parts is uniform. In order to better prevent loosening, the surface of the belleville washers is generally processed to form streaks.

[0003] In the existing process of processing the streaks on the surface of butterfly washers, the upper and lower molds are usually closed by stamping to deform the surface of the gasket to form streaks. After the upper and lower molds are separated, materials can be manually loaded into the mold groove, which greatly affects the processing efficiency and is inconvenient to load materials when the molds are closed. In addition, if the upper mold falls accidentally, there is a possibility of squeezing and damage to the operator's hands, and the safety is low. Therefore, we propose a butterfly washer mold and stamping system. Summary of the invention

[0004] The object of the present invention is to provide a butterfly washer die and a punching system to solve the problems raised in the above background technology.

[0005] To achieve the above object, the present invention provides the following technical solution: a butterfly washer mold, comprising:

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] The present invention is provided with two lower molds and a rotating adjustment component, thereby avoiding the traditional method of being inconvenient to place the gasket at the same time during stamping processing. The gasket needs to be placed on the lower mold after stamping, which is inefficient and there is a risk of the upper mold moving downward to squeeze the operator's hand during placement. The device has a simple structure and is convenient for placing the gasket through another lower mold during stamping, and there is no risk of the upper mold accidentally squeezing the hand. The device has high safety, is easy to operate, and has improved practicality. BRIEF DESCRIPTION OF THE DRAWINGS
