Abstract

The invention relates to a laser segment-scanning plate bending forming device and method. The method comprises the steps that a metal plate to be machined is placed below a first scanning head and a second scanning head; scanning paths and scanning powers of a first laser device and a second laser device are set through a computer; the scanning paths of the first laser device and the second laser device are connected in the middle of the metal plate, and the scanning powers gradually decrease from the edges of the metal plate to the middle of the metal plate; the first scanning head and the second scanning head moves face to face and starts to scan along the respective scanning paths. Through the laser segment-scanning plate bending forming device and method, difference of laser bending angles in all positions of the metal plate can be reduced, the boundary effect is avoided, and the forming quality of plates improved.

Description

technical field [0001] The invention relates to the field of plate forming, and relates to a method for realizing plate forming and bending using laser as a heat source, in particular to a laser segment scanning plate bending forming device and a laser segment scanning bending forming method. Background technique [0002] Laser bending forming technology is an emerging plastic processing method. Plastic forming of sheet metal is generally divided into two types: cold forming and hot forming. Cold forming includes rolling processing, molding processing and multi-pressure head forming. Forming and local heat forming. Laser bending forming belongs to the local heating forming process in thermoforming. As an aspect of laser application, laser bending forming technology has the advantages of high efficiency, flexibility and cleanliness compared with traditional local heating forming technology. Compared with the traditional metal forming process, laser bending does not require ...
