Description

Technical Field

[0001] The utility model relates to the technical field of stamping equipment, in particular to a positioning fixture used for valve core stamping. Background Art

[0002] Faucet is a popular name for water valve, which is used to control the size of water flow and has the effect of saving water. The faucet valve core is the most important part of the faucet. The valve core is the valve part that the valve body uses to achieve the basic functions of direction control, pressure control or flow control by moving it;

[0003] There are many components inside the valve core. During processing, the required pipe fittings need to be stamped. Stamping can expand the diameter of the pipe at the opening of the pipe fitting, so as to facilitate subsequent assembly. However, when the existing stamping device punches and expands the hole of the pipe fitting, the pipe fitting is directly inserted into the positioning column, and then the punching machine is started to process it through the punching head. Although this can quickly stamp the pipe fitting, the pipe fitting is very unstable if it is only connected by sleeve, which is easy to affect the stamping. Utility Model Content
