Parts made of elastic materials deform under external force and return to their original shape after the external force is removed. It is also called "spring". It is generally made of spring steel. There are many types of springs. According to the shape, there are mainly spiral springs, scroll springs, leaf springs, special-shaped springs, etc. However, during the coiling process of the spring, the end of the steel wire used to make the spring needs to be clamped.

[0053] During continuous welding, welding fumes will continue to be generated, causing the surrounding environment to deteriorate, and these fumes will enter the human body through the respiratory tract, causing certain harm to the body of the workers. For this reason, the following is a specific implementation plan of the spring wire butt processing clamping device according to the present application with reference to the accompanying drawings: Specifically, if Figure 1 , Figure 10-11 As shown, in a specific embodiment of the present invention, the first side plate 170 and the second side plate 190 form an air flow channel, and a smoke cleaning mechanism 900 is installed at one end of the air flow channel.

The adsorption cover 930 is fixed to one end of the workbench 100, and the end cover of the adsorption cover 930 is arranged at the end of the crawler 310. By controlling the operation of the exhaust fan 910, a negative pressure adsorption effect is generated at the end of the adsorption hood 930, and the smoke generated during the welding process is sucked into the adsorption hood 930 for filtration. Due to the airflow channel formed by the first side plate 170 and the second side plate 190, the generated smoke is not easy to spread, which facilitates the collection of smoke, so that the working space maintains a good environmental state and eliminates safety hazards.

[0055] In a specific embodiment of the present invention, the adsorption hood 930 is filled with a granular filler for adsorbing welding fumes, and the air outlet of the exhaust fan 910 is connected to a bag filter; and a detachable mesh plate is clamped at the port of the adsorption hood 930.
