Tinned sheet manufacturing and machining method

Abstract

The invention relates to a tinned thin plate manufacturing and machining method. The method uses rust removal equipment, the rust removal equipment comprises a base, an unwinding device, a winding device and a middle rust removal device. A sheet is wound and passes through a primary rust removal rod, the primary rust removal rod carries out primary rust removal on the sheet; a winding motor is started, And the output end of the winding motor drives a winding roller to rotate, so that the sheet clamped on the winding roller can be wound, and therefore unwinding and winding can be carried out at the same time; a driving motor is started, and the output end of the driving motor drives a gear to rotate, so that the upper end face and the lower end face of the sheet can be subjected to full polishing and rust removal by the opposite or relative movement of a upper rust removal roller and a lower rust removal roller; a suction pump is started, the upper end face and the lower end face of the sheet make contact with an upper dust collection roller and a lower dust collection roller correspondingly, the suction pump sucks out impurities and dust on the surface of the sheet from through holes, and the two dust collection rollers roll, so that dust absorption glue above the dust absorption rollers can wipe impurities and dust which are not absorbed on the upper end face and the lower end face of the sheet.

Description

technical field [0001] The invention relates to the technical field of tin-plated sheets, in particular to a method for manufacturing and processing tin-plated sheets. Background technique [0002] Tin-plated sheet refers to a steel sheet plated with a thin layer of metallic tin on the surface. Tinplate is a low carbon steel rolled into a steel plate with a thickness of about 2mm, after pickling, cold rolling, electrolytic cleaning and annealing, leveling, trimming, and then cleaning, electroplating, reflow, passivation, and oiling. Cut into finished products of tinplate. The tin used for tinplate is high-purity tin, and the tin layer can also be coated by hot dip plating. For purification treatment, the tin-plated sheet consists of five parts, which are the steel substrate, tin-iron alloy layer, tin layer, oxide film and oil film in order from the inside to the outside. The upper and lower surfaces of the substrate are ground and derusted to facilitate subsequent processi...

AI Technical Summary

Problems solved by technology

[0004] (1) Due to the need to grind and derust the coils of the steel substrate, and the diameter of the coils is large, the existing device cannot realize grinding and derusting while unwinding and rewinding the coils;

[0005] (2) While unwinding and rewinding the coil, the existing device cannot realize simultaneous grinding of the upper and lower surfaces of the coil, and when grinding and derusting, the thin plate is pulled forward, and the existing device cannot realize the grinding of the thin plate Pulling and grinding at the same time;

[0006] (3) After the coil is polished, excess impurities are attached to the surface of the thin plate. If it is not cleaned up in time, it will affect the subsequent use effect. for dust removal
