Description

Technical Field

[0001] The present application relates to the technical field of steel plate processing, and in particular to a device for polishing a curved steel plate. Background Art

[0002] Steel plate processing refers to the process of performing various processing operations on steel plates to meet different engineering and manufacturing needs. Arc polishing of steel plates can improve their appearance quality and surface finish, increase corrosion resistance and wear resistance, making them more suitable for decoration, construction, furniture and other fields, while also improving the overall quality of the steel plates.

[0003] In the patent document with the published announcement number CN113059458B, a galvanized steel plate polishing and grinding device is provided, including a bottom plate, a clamping and locking mechanism and a curved surface polishing mechanism, wherein the clamping and locking mechanism is arranged in the middle of the upper end surface of the bottom plate, and the curved surface polishing mechanism is arranged above the clamping and locking mechanism, and the curved surface polishing mechanism is installed on the bottom plate. The present invention can solve the problem that the existing galvanized steel plate welding processing device cannot stably clamp and lock according to the size of the galvanized steel plate at the bottom, resulting in the arc steel plate shaking when grinding the curved steel plate on its surface, affecting the grinding efficiency and grinding quality, and easily causing damage to the grinding head in severe cases, causing economic losses and poor applicability. It can also solve the problem that the existing galvanized steel plate welding processing device cannot grind and polish the curved surface of the curved steel plate before galvanizing, resulting in rust impurities on the surface of the curved steel plate affecting the galvanizing effect and the smoothness of the surface after galvanizing, affecting the use value of the curved steel plate after welding.

[0004] The above device realizes the arc polishing of the steel plate through the arc polishing mechanism. When the fixed belt is used to polish the steel plate, four rotating handles need to be adjusted to clamp the two sides of the steel plate, which is relatively complicated to operate. The threaded connection mode of the locking screw makes the adjustment efficiency low. When the front and back of the steel plate are clamped, the clamping force is maintained by the tension provided by the spring, so that the clamped steel plate will be subjected to different degrees of clamping force due to different lengths. If the clamping force is too small, the steel plate will be unstable, thereby affecting the polishing effect. Utility Model Content
