Galvanizing processing pretreatment method for high-strength bolt manufacturing

Abstract

The invention relates to a galvanizing processing pretreatment method for high-strength bolt manufacturing. The galvanizing processing pretreatment method for high-strength bolt manufacturing utilizes a galvanizing processing device for high-strength bolt manufacturing. The galvanizing processing device for high-strength bolt manufacturing comprises a supporting plate, a processing mechanism and a clamping mechanism. Bolts of different sizes are flushed according to the principle of air bag contraction, and the processing efficiency of the bolts is improved. A bolt is clamped through the clamping mechanism, and a loading cylinder synchronously rotates along with the bolt, so that the stability of the bolt is improved. The processed bolt can be automatically conveyed to be detached from processing rollers by changing the rotating direction of a rotating motor. In addition, cleaning branched chains are used for repeatedly flushing the bolt along with the rotating direction of the rotating motor, so that the cooling effect is achieved. The effect of grinding and cleaning the bolt can be achieved through the processing mechanism, so that the processing cost of bolts is saved.

Description

technical field [0001] The invention relates to the technical field of bolt manufacturing and processing, in particular to a pretreatment method for high-strength bolt manufacturing and galvanizing processing. Background technique [0002] Bolts are cylindrical threaded fasteners with nuts. There are many names for bolts. Everyone’s name may be different. Some people call them screws, some people call them bolts, and some people call them fasteners. There are so many names, but the meaning is the same. They are all bolts. Bolts are a general term for fasteners. Bolts are divided according to the shape of the head: hexagonal head, round head, square head, countersunk head, etc. . In the later use of bolts, due to the different working environments, the surface of the bolts is prone to corrosion. In order to reduce the corrosion of the outside world, the existing processing manufacturers usually use the method of galvanizing the surface of the bolts. Before galvanizing the bo...

AI Technical Summary

Problems solved by technology

[0003] 1. A lot of debris will be generated during grinding. The common treatment method is to use a water spray pipe to spray water on the same position on the surface of the workpiece. When it is necessary to repeatedly rinse bolts of different lengths and thicknesses, it is necessary to frequently move the spray The position of the water pipe makes the work less efficient and makes the work more cumbersome;

[0004] 2. In the prior art, when the bolts are polished and cleaned, a single method is used to process and clean the surface of the bolts. When the processed bolts need to be taken out from the upper end of the processing roller, it is easy to cause a lot of human labor. , which leads to cumbersome operation and increases the cost of processing bolts
