Description

Technical Field

[0001] The utility model relates to the technical field of valve production, in particular to a shearing device for valve production. Background Art

[0002] Shearing devices for valve production are commonly used to cut and shape metal sheets when manufacturing valves. They usually include a pair of scissors or knives that can cut along the edges of the metal sheet to ensure the metal sheet is of the desired size and shape.

[0003] The shearing device in the prior art does not have the function of cooling the tool. Since a large amount of heat is generated by the friction between the tool and the metal sheet during high-frequency cutting, the lack of cooling measures will cause the tool temperature to rise and increase the wear rate of the tool. Long-term high temperature will reduce the hardness and wear resistance of the tool, shorten the service life of the tool, and increase the cost of tool replacement.

[0004] Therefore, it is necessary to design a shearing device for valve production to solve the above problems. Utility Model Content

The other end of the connecting rod extends to the outside of the sealing cylinder and is fixedly connected to the lifting knife seat. One end of the air pipe is connected to the sealing cylinder.

[0009] As a preferred technical solution of the utility model, the cooling assembly includes a cooling box and a cooling pipe. The cooling box is fixed on the shearing device, and coolant is accumulated inside the cooling box.

[0012] As a preferred technical solution of the present utility model, the cooling pipe has a spiral structure.

[0013] As a preferred technical solution of the utility model, a semiconductor refrigeration sheet is installed on the inner surface of the cooling box.

[0014] The utility model has the following beneficial effects:

[0015] The low-temperature gas sprayed through the air jet hole can effectively reduce the temperature of the shearing knife, avoiding problems such as increased tool wear and reduced dimensional accuracy caused by excessive temperature during high-frequency punching.
