Switch laser cutting machine and cutting machining method

Abstract

The invention discloses a switch laser cutting machine which comprises a machine tool, a feeding table, a laser head, an X-axis drive mechanism, a Y-axis drive mechanism, a Z-axis drive mechanism, a workbench, a lifting mechanism and a dragging mechanism. The dragging mechanism comprises a driving roller, a driven roller, a transmission chain and a first drive motor, the driven roller and the driving roller are oppositely arranged in a front-back mode, the transmission chain is wound between the driving roller and the driven roller, the driving roller is in transmission connection with an output shaft of the first driving motor, the transmission chain is provided with two traction wheels, a traction piece is fixedly arranged at the rear end of the workbench, an open groove is formed in the traction piece, the transmission chain drives the workbench to move back and forth between the machine tool and the feeding table through cooperation of the traction wheels and the open groove, when the workbench stops moving, the two traction wheels are located at the front and back ends of the transmission chain, and the axis of the driving roller and the axis of the driven roller are located on the same horizontal plane. The cutting efficiency can be improved, and the service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of metal plate plane cutting equipment, in particular to an exchange laser cutting machine and a cutting processing method. Background technique [0002] The laser cutting machine replaces the traditional mechanical knife with an invisible beam. It has the characteristics of high precision, fast cutting, not limited to cutting patterns, automatic typesetting to save materials, smooth incision, and low processing cost. It will gradually improve or replace it. Traditional metal cutting process equipment. The mechanical part of the laser head has no contact with the workpiece, and will not scratch the surface of the workpiece during work; the laser cutting speed is fast, the incision is smooth and flat, and generally no subsequent processing is required; the cutting heat-affected zone is small, the deformation of the plate is small, and the kerf is narrow ( 0.1mm~0.3mm); the incision has no mechanical stress, ...

AI Technical Summary

Problems solved by technology

[0003] Traditional laser cutting machines generally adopt manual loading and unloading. After completing a cutting process, the operator needs to spend a lot of time on unloading, cleaning and loading, which leads to the downtime of the laser cutting machine in the middle of two cutting processes. Longer, lower cutting efficiency, high waiting cost

[0004] In response to this problem, some merchants have a laser cutting machine, which includes a machine tool, a feeding table, two workbenches and a drag mechanism. Driven to move back and forth between the machine tool and the loading table, but there will be a problem. After the drag mechanism controls the workbench to stop, based on the principle of inertia, the workbench will still have kinetic energy in the horizontal direction, and this kinetic energy is only at this time. It can affect the machine tool and cause impact on the machine tool. In the long run, it will cause wear and tear on the machine tool, reduce the durability of the machine tool, and thus reduce the service life of the laser cutting machine
