Description

Technical Field

[0001] The utility model relates to the technical field of elevator accessory processing, in particular to a laser cutting and blanking device for processing elevator angle steel. Background Art

[0002] Laser cutting is one of the thermal cutting methods. It uses a high-power density laser beam focused on the workpiece to quickly melt, vaporize, ablate or reach the ignition point of the irradiated material. At the same time, the molten material is blown away by a high-speed air flow coaxial with the beam, so as to cut the workpiece. Laser cutting can be divided into four categories: laser vaporization cutting, laser melting cutting, laser oxygen cutting, and laser scribing and controlled fracture. During the processing of elevator accessories, laser cutting is usually used to cut and process electrical accessories. However, currently, after laser cutting, the temperature of elevator accessories will rise, making it difficult to blank the cut elevator accessories.
