Description

Technical Field

[0001] The invention relates to the technical field of laser cutting machines, and in particular to a high-precision laser cutting machine with a tightening function. Background Art

[0002] Laser cutting machine is a machine that uses laser technology for cutting. It can use high-power density laser beam to accurately and quickly cut various materials. Compared with traditional cutting methods, laser cutting machine has the advantages of high precision, fast cutting speed, good incision quality, and a wide range of applicable materials. The working principle of laser cutting machine is to focus the laser emitted by the laser into a high-power density laser beam through the optical path system, and then irradiate it on the material to be cut. Due to the high power density of the laser beam, it can melt or vaporize the material in a very short time to form an incision. The cutting head and workpiece of the laser cutting machine will move relative to each other according to the predetermined path, thereby achieving continuous or intermittent cutting. It can be known from patent publication number CN108672962B that a high-precision laser cutting machine with cooling and cleaning functions is disclosed, including a base, a controller, a processing box, a ventilation mechanism and four legs. A plane moving device, a laser head and two clamping mechanisms are arranged in the processing box. The clamping mechanism includes a translation component, a translation plate, a switching component, a switching shaft, a connecting rod and two clamping components. The switching component includes a first gear, a rack, an air pump, a cylinder and a piston. The ventilation mechanism includes a driving component and two ventilation components. The high-precision laser cutting machine with cooling and cleaning functions fixes the workpiece through the clamping mechanism. After the laser head cuts one side of the workpiece, the clamping mechanism drives the workpiece to flip so that the laser head cuts the other side, thereby improving the cutting accuracy of the conical laser beam. Moreover, the ventilation mechanism strengthens the flow of air during cutting, so that the air takes away the heat generated by the cutting and the vaporized metal, thereby achieving cooling and cleaning and improving the practicability of the equipment.

[0003] The prior art selects appropriate cutting parameters according to the cutting plan, places the metal steel pipe to be cut on the workbench of the laser cutting machine and fixes it, then adjusts the focus of the cutting head to a certain point. In order to ensure the stability of the metal steel pipe during the cutting process, the pipes are transferred to the feeding mechanism one at a time and smoothly and regularly as required, and are automatically replenished and on standby according to the operating speed.
