Acid washing equipment for hardware production

Abstract

The invention discloses acid washing equipment for hardware production. The equipment comprises a main frame, multiple support rods, an upper support plate, a rolling cage, a rolling cage fixed support frame, a lifting device, a transverse moving device, an annular rack, a rotating motor and a motor gear; three pool bodies are transversely arranged at the upper end of the main frame in sequence, and are respectively an acid washing pool, a clear water pool and a drained water collecting pool; acid washing liquid is filled in the acid washing pool; clear water is filled in the clear water pool;the multiple support rods are arranged on two sides of the upper end of the main frame; the upper support plate is horizontally arranged at the upper ends of the support rods; the transverse moving device is transversely arranged at the lower end of the upper support plate; and the lifting device is arranged at the lower end of the transverse shifting device. The rolling cage is arranged at the upper end of the frame; through cooperation between the rolling cage and the acid washing pool, the acid washing is performed on screws; and through rotation of the rolling cage, the uniform contact between the surfaces of the screws and acid washing solution is facilitated, so that the acid washing quality is improved, and the acid washing efficiency is improved.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of screw production equipment, in particular to the technical field of pickling equipment for screw production. [0003] 【Background technique】 [0004] Screws are commonly found in machinery, electrical appliances, and buildings. They are generally made of metal or plastic and are cylindrical in shape. The surface is engraved with concave-convex grooves called threads. The main function of screws is to join two objects or fix the position of an object. , screws can usually be removed and retightened at will without loss of efficiency. Generally, the top of the screw has a large diameter, and the common ones are round, square or regular hexagonal. If the top is regular hexagonal, you can use a wrench to turn the screw. If the top is round, there will be grooves on the front of the top for easy use. screwdriver turns the screw. The most common grooves are one-shaped, cross-shaped, and square, and th...

AI Technical Summary

Problems solved by technology

The most common grooves are one-shaped, cross-shaped, and square, and there are other shapes. The production of screws shows off that they can only be produced through the processes of plate, annealing, pickling, drawing, heading, heat treatment, and electroplating. This is a screw. The complete process, pickling is an essential and important process in the production and processing of screws. Pickling is to use acid solution to remove scale and rust on the steel surface. It is a method to clean the metal surface. Pickling equipment, pickling is not thorough, the quality of pickling is poor, the surface of many screw raw materials is not pickled, and the pickling efficiency is low, which cannot meet the existing production needs
