Efficient laser cutting equipment for aluminum alloy plate machining

Abstract

The invention relates to efficient laser cutting equipment for aluminum alloy plate machining. The equipment comprises a workbench, a driving box and a laser; the driving box is arranged above the workbench and is fixedly connected with the workbench; the laser is arranged at the bottom of the driving box; a laser generation system is arranged on the driving box; a moving device is arranged on theworkbench. An auxiliary mechanism is arranged at the bottom of the driving box; a dust collection mechanism is arranged on the driving box; and the auxiliary mechanism comprises a fixed pipe, a rotating pipe, a connecting ring, an electromagnet, a first bearing, a driving assembly, three balls and three pushing assemblies. According to the efficient laser cutting equipment for aluminum alloy plate machining, the function of collecting dust in air is achieved through the dust suction mechanism; and in addition, the function of removing impurities on the workpiece is achieved through the auxiliary mechanism, the situation that the laser absorption rate of the workpiece is affected by the impurities is avoided, and the cutting efficiency is improved.

Description

technical field [0001] The invention relates to the field of laser equipment, in particular to a high-efficiency laser cutting equipment used for processing aluminum alloy plates. Background technique [0002] Laser cutting machine is a kind of laser equipment. Laser cutting is the horizontal laser beam emitted by the laser, which is transformed into a vertical downward laser beam through a 45° total reflection mirror, and then focused by a lens to form a very small spot at the focal point. , the focused laser power density at the spot is as high as 10^6~10^9W / cm^2. The workpiece at its focal point is irradiated by the high-power-density laser spot, which will generate a local high temperature above 10,000°C, which will vaporize the workpiece instantly, and then cooperate with the auxiliary cutting gas to blow away the vaporized metal, thereby cutting the workpiece into a small With the movement of the CNC machine tool, countless small holes are connected to form the shape ...

AI Technical Summary

Problems solved by technology

[0003] Existing laser cutting machines will produce a lot of dust during the cutting process of aluminum alloy workpieces, which will be harmful to the human body after inhalation and reduce safety. Not only that, but when there are impurities on the workpiece, it will affect the quality of the workpiece. The absorption rate of laser light, thus reducing the cutting efficiency
