Description
Technical Field
[0001] The utility model relates to the technical field of spring production, in particular to a surface treatment device for spring manufacturing. Background Art
[0002] A spring is a mechanical part that uses elasticity to work. During the spring manufacturing process, it is easily corroded by the surrounding medium. Corrosion will change the elastic force of the spring. By treating the surface of the spring, its performance can be improved and its service life can be extended.
[0003] In the prior art, polishing equipment is usually used to process the surface of the spring. The existing polishing equipment is mainly composed of a motor, a polishing chamber and steel shots. When the spring surface is processed, the motor is operated to rotate the polishing chamber, and the steel shots or other granular materials are projected onto the spring surface to be processed through high-speed rotation. When the steel shots collide with the metal surface, a strong impact force is generated. This impact force can effectively remove surface dirt, oxide layer and residue, thereby processing the spring surface.
[0004] When the existing spring surface treatment device is in use, a large amount of debris will be generated due to the continuous collision and friction between the workpiece and the steel shot abrasive in the tank body, and the debris is not easy to be discharged, so it mixes with the steel shot abrasive, thereby affecting the subsequent polishing effect; therefore, a spring manufacturing surface treatment device is proposed to address the above problems.
