Technical Field

[0001] This utility model relates to the field of electromagnetic valve assembly technology, specifically to an electromagnetic valve magnetic sheet riveting and ejection device. Background Technology

[0002] Solenoid valves are electromagnetically controlled industrial devices, serving as fundamental components in automation systems for fluid control. They are actuators, not limited to hydraulic or pneumatic systems, used in industrial control systems to adjust the direction, flow rate, speed, and other parameters of the medium. Solenoid valves can be used with different circuits to achieve the desired control, ensuring both precision and flexibility. There are many types of solenoid valves, each playing a different role in the control system. The most common types include check valves, safety valves, directional control valves, and speed regulating valves.

[0003] When assembling a solenoid valve, one of the steps is to assemble the magnetic plate onto the valve shaft. Currently, this step involves placing the magnetic plate and the valve shaft on a riveting mechanism, then activating the riveting mechanism to rivet the valve shaft and the magnetic plate together. The riveted valve shaft and magnetic plate are then manually removed. This method is time-consuming, labor-intensive, and inefficient. Utility Model Content
