Problems solved by technology
Among them, metal screws are easily corroded by water vapor in the environment. In order to slow down the corrosion of metal screws, people will coat the outside of the screw. Compared with electroplating coating, the cost of electroless coating is lower, and it is more suitable for screws with stainless steel as the base material. , while the existing electroless coating equipment mostly simply immerses the plated parts in the plating solution, the quality of the coating film obtained is poor, and the thickness of the formed coating film is uneven, which affects the performance of the screw. Therefore, it is necessary to propose a screw surface Coating equipment

The invention discloses screw surface coating equipment. The screw surface coating equipment comprises a lifting frame, a guide rail, a lifting mechanism, a plating bath, a rinsing tank, limiting slots, and drum mechanisms; the guide rail is arranged at the bottom of a cross beam of the lifting frame; the lifting mechanism is arranged on the guide rail; the plating bath and the rinsing bath are arranged below the cross beam of the lifting frame; the plating bath is located on the left side of the rinsing bath and is filled with plating liquid; the rinsing tank is filled with clean water; wallsof the plating bath and the rinsing tank are provided with limiting slots; and the limiting slots are internally equipped with the barrel mechanisms. Compared with the prior art, the screw surface coating equipment is simple in structure and reasonable in design, and can continuously stir screw raw materials during the chemical coating process, and at the same time, the screw raw materials are bombarded with external airflow and ultrasonic waves, so that the screw raw materials are in full contact with the chemical plating liquid, and a dense and uniform chemical plating film is obtained.
Description
【Technical field】 [0001] The invention relates to the technical field of fastener processing, in particular to a screw surface coating equipment. 【Background technique】 [0002] Screw refers to a screw, which is a tool for gradually tightening the mechanism of the object by using the physical and mathematical principles of the oblique circular rotation and friction of the object. Screw is a general term for fasteners, a daily colloquial language. [0003] Screws are a common fastener widely used in machinery, electrical appliances and buildings. The general material is metal or plastic, and it is cylindrical in shape, and the concave-convex grooves engraved on the surface are called threads. Among them, metal screws are easily corroded by water vapor in the environment. In order to slow down the corrosion of metal screws, people will coat the outside of the screw. Compared with electroplating coating, the cost of electroless coating is lower, and it is more suitable for sc...
