Repeated bending and rolling unit with electrified auxiliary device

Abstract

The invention discloses a repeated bending and rolling unit with an electrified auxiliary device, and belongs to the field of machining. Three rolling mills are sequentially fixed on a rail seat, the rolling mills are two-roller rolling mills, each rolling mill comprises a screw-down device, a roller, a rolling mill rack, a bearing seat, a bearing, a base, a roller adjusting device, an upper roller balancing device and an electrifying device, and the two sides of the lower bearing seat of each rack and the front and back of each roller are provided with a group of electrifying devices correspondingly. The electrifying devices can stretch and retract front and back to adapt to rolled pieces of different models and shapes, the rolled pieces are transversely electrified through the electrifying devices and enter the rolling mills, repeated bending rolling is achieved through rollers of special shapes, the electrifying state of each rolling mill can be independently adjusted, diversified rolling schemes can be achieved, cost is saved, operation and use are convenient, and safety performance is high.

Description

Technical field[0001]The present invention relates to a repeated curved unit of a charge auxiliary device, belonging to the field of machining.Background technique[0002]The steel industry has strongly supported and promotes the development of the relevant industries, promoting social employment, the use of slabs in the steel industry is extremely extensive, from architecture, water conservancy, bridges cover all walks of life, especially my country's aerospace industry and shipping industry Developing the plate shape, mechanical properties, corrosion resistance, strength and other aspects of the board strip, have put forward higher requirements. With the rapid development of the manufacturing industry, users have more and more demanding the performance requirements of the finished sheet and strip. In view of the above analysis, improve the quality of the steel plate shape is necessary, need to excerfene, what we currently face is that the quality of the steel plate is not high, so w...

AI Technical Summary

Problems solved by technology

It mainly improves the existing plate bending forming process, changes the corresponding structure on the basis of the existing stamping die, and combines it with the external electric field to solve the problems of large rebound and difficult bending of ultra-high-strength plates during the bending process ; It improves its bending forming characteristics, makes it meet the forming requirements of bending workpieces, and improves the service life of the die. However, for longer strips, the efficiency of die forging is not as good as that of roll forging, and it is not conducive to continuous forging processing.
