AI Technical Summary

Technical Problem

Prior Art In the process of processing battery steel shells, one side of the steel shell needs to be closely fitted with the internal structure of the battery, but the sliding friction between the steel shell and the roller during processing results in burrs on the surface of the steel plate, damaging the pole plate inside the battery.

Method used

A roll forming equipment is designed, and the lower fixed roller and the upper movable roller are combined to perform rolling. The diameters of the lower fixed roller are different, so that the steel plate is unfolded to both sides in an orderly manner during the rolling process. The upper movable roller can move and rotate with the steel plate to prevent burrs caused by sliding friction.

Benefits of technology

It effectively prevents sliding friction between the upper movable roller and the upper surface of the steel plate during the rolling process, maintains the smoothness of the upper surface of the steel plate, and ensures the extension effect of the steel plate, avoids the occurrence of burrs on the surface of the steel plate, and improves the processing quality of the battery steel shell.

Abstract

The invention relates to the technical field of metal plate processing, and discloses rolling forming equipment and a forming method for battery steel shell processing, the rolling forming equipment comprises a device main body, a feeding mechanism is mounted at the top of the device main body, and a plurality of rolling mechanisms are mounted at the top of the device main body. In the rolling process, the lower fixed roller and the upper movable roller are used for rolling a steel plate, and when the lower fixed roller is used for rolling the lower surface of the steel plate, grains with different diameters on the lower fixed roller can enable the steel plate to be orderly unfolded towards the two sides in the rolling process; the upper movable roller can be driven to rotate in the moving process of the steel plate, and the upper movable roller is driven to rotate through movement of the steel plate, so that burrs on the upper surface of the steel plate caused by sliding friction between the upper movable roller and the upper surface of the steel plate in the rolling process can be effectively prevented; therefore, the extension effect in the rolling process is guaranteed, and the upper surface of the steel plate can be kept smooth as much as possible.
