Description

technical field [0001] The invention belongs to the field of mandrel processing, and relates to a mandrel surface treatment technology, in particular to a surface anti-hard processing system for mandrel processing. Background technique [0002] The mandrel is a long-axis workpiece, which is a deformation tool in the production of seamless steel pipes. It has a long length and is a workpiece used under extremely harsh conditions of high temperature and high pressure, so it requires high processing technology. In order to improve the wear resistance and pressure resistance of the mandrel during use, it is necessary to carry out anti-hard processing on the surface of the mandrel. It does not deform or fall off under the action of the mandrel. It is usually necessary to spray the surface of the mandrel to meet the higher technical parameter requirements. [0003] The spraying treatment is mainly to form a coating film on the surface of the mandrel through the migration of the p...

AI Technical Summary

Problems solved by technology

[0003] The spraying treatment is mainly to form a coating film on the surface of the mandrel through the migration of the positive and negative electrodes of the electrification to realize the hard-resistant processing technology. The existing spraying equipment is relatively traditional, and the shunt effect is poor; the uneven spraying on the surface of the mandrel is the influence The main technical problem of resistance to hard machining, and the mandrel transfer structure is only a single carriage, and the lateral dimension and horizontal alignment need to be manually adjusted.

[0004] The large error and time-consuming operation greatly affect the work efficiency of the mandrel surface against hard machining, especially the processing requirements of mandrels of various specifications cannot be met; in addition, spraying processing fluid will be generated after the mandrel surface is sprayed. , usually all need to be recycled. The recycling in the prior art is relatively simple, usually a simple recovery tank or a recovery bucket, which is inefficient and prone to leakage, which reduces the processing and production efficiency and if the recovered liquid cannot be handled well, it will be harmful to the Production poses safety hazards and is not environmentally friendly
