Bending mechanism for solenoid valve coil pin

Abstract

The invention relates to the technical field of electromagnetic valve coil pin welding, in particular to an electromagnetic valve coil pin bending mechanism which comprises a first 45-degree bending assembly and a second 90-degree bending assembly which are installed on a workbench of coil welding equipment. The first 45-degree bending assembly and the second 90-degree bending assembly are arranged at welding grooves in the periphery of a rotary disc on the workbench. The first 45-degree bending assembly and the second 90-degree bending assembly are the same in structure. The first 45-degree bending assembly comprises a guide cylinder, a product positioning air cylinder is installed on the upper portion of the guide cylinder, and a cylinder shaft of the product positioning air cylinder is connected with a horizontal positioning block. A first clamp component is arranged in the middle of the guide cylinder. A bending air cylinder assembly is arranged on the lower portion of the guide cylinder. The electromagnetic valve coil pin bending device has the advantages that the electromagnetic valve coil pin can be automatically bent, tin adding and welding on the electromagnetic valve coil pin in the subsequent working procedure are facilitated, line production is formed, and the working efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of solenoid valve coil pin welding, in particular to a bending mechanism for solenoid valve coil pins. Background technique [0002] Solenoid valve is an automatic basic component used to control fluid, which belongs to actuator and is not limited to hydraulic and pneumatic. Different solenoid valves play a role in different positions of the control system, and the most commonly used ones are check valves, safety valves, directional control valves, speed regulating valves, etc. There is a closed cavity in the solenoid valve, and there are through holes in different positions. Each hole is connected to a different oil pipe. There is a piston in the middle of the cavity, and two electromagnets on both sides. On the other hand, different oil discharge holes are opened or closed by controlling the movement of the valve body, while the oil inlet hole is normally open, the hydraulic oil will enter different oil d...

AI Technical Summary

Problems solved by technology

The traditional way is to manually use hardware tools to realize the bending operation of the coil pins sleeved on the valve body, which has slow speed and low work efficiency, which seriously affects the overall installation and operation of the solenoid valve.

It also increases the production cost per unit time, which eventually leads to an increase in the price of the solenoid valve, which is not conducive to the later market competition
