AI Technical Summary

Technical Problem

The existing cold-rolled steel strip coiling device lacks positioning structure on the forming die, resulting in problems of bias welding or edge curling during the steel strip welding process.

Method used

A cold-rolled steel strip coil device is designed, and the steel strip is quickly positioned by cooperating with the limiting plate and magnet. The lifting assembly and the driving assembly are used to ensure the accurate abutment between the steel strip and the forming roller, and smooth movement is achieved through the guide assembly and the guide rail, and the rubber pad buffer is combined to avoid collision.

Benefits of technology

The accuracy of steel strip coil forming is improved, the bias welding and edge curling of steel strips are avoided during welding, and the processing accuracy and efficiency are improved.

Abstract

The utility model discloses a cold-rolled steel strip rolling device which comprises a device body, a forming roller, a flat plate, a first forming die and second forming dies, the forming roller and the flat plate are installed on the device body, the first forming die and the second forming dies are installed on the flat plate, the first forming die is located under the forming roller, and the second forming dies are arranged on the two sides of the first forming die in pairs. A lifting assembly for lifting the flat plate to be close to the forming roller is arranged at the bottom of the device body, paired driving assemblies for pushing the second forming die to be close to the forming roller are arranged on the flat plate, a limiting plate for positioning a steel belt is arranged at one end of the inner side of the first forming die, and the first forming die is half-surrounded by the limiting plate. The limiting plate is provided with a first notch for avoiding the forming roller, and the second forming die is provided with a second notch for avoiding the limiting plate. According to the technical scheme, through cooperation of the limiting plate and the magnet, the steel belt installed on the first forming die can be rapidly installed and positioned, and the rolling forming precision of the steel belt is improved.
