AI Technical Summary

Technical Problem

The existing robotic rolling edge-sealing process cannot meet the rolling edge requirements of high-strength steel plates due to insufficient rolling pressure.

Method used

A laser heating mirror assembly is used to pre-soften high-strength steel plates. Combined with a rolling device connected by a 3-DOF servo articulated arm, the laser heating and rolling are synchronized. The angle and position of the laser heating mirror assembly are controlled by the servo articulated arm, and temperature feedback control is achieved in conjunction with an infrared temperature detection sensor.

Benefits of technology

The rolling pressure during the rolling process is reduced, which can effectively complete the rolling operation of high-strength steel plates and improve the efficiency and quality of the rolling process.

Abstract

The utility model discloses a pinch roller assembly capable of realizing edge rolling operation of a high-strength steel plate workpiece, which comprises a laser heating mirror group for pre-softening a high-strength steel plate to be subjected to edge rolling operation, a rolling device for carrying out edge rolling operation on the pre-softened high-strength steel plate, and a servo articulated arm for connecting the laser heating mirror group and the pre-rolling device, therefore, the laser lens group obtains appropriate heating light spots and orientations relative to the edge rolling head according to the angle and position conditions. According to the pressing wheel assembly, on one hand, laser of the laser heating mirror set is adopted for heating a local area of a high-strength steel plate, then the edge rolling effect is achieved, then the rolling force in the edge rolling process is reduced, and the laser mirror set can adjust the angle and position conditions relative to an edge rolling head so as to obtain appropriate heating light spots and orientation; and on the other hand, the laser heating mirror set and the rolling device can be jointly installed on the mechanical arm by means of the servo articulated arm, and synchronization of laser annealing and rolling operation is achieved.
