Abroad, laser cutting equipment for square tube processing is relatively mature, but the price is high, generally the unit price is more than 6 million yuan, and it cannot adapt to the domestic passenger car industry's small batch and multi-variety production and operation model. Fitness equipment and other industries with a single variety and a large batch of industries, otherwise, the value of high precision and high speed of laser cutting cannot be exerted. Therefore, in terms of price, maintenance, and passenger car industry comparison, foreign laser cutting equipment does not have the prospect of large-scale application in China. At the same time, the domestic research on laser gas cutting equipment for tube processing is urgent. Our company cooperated with laser cutting technology company to develop the first domestic laser cutting equipment for passenger car square tube processing. The prototype experiment has been for 6 months. The cutting accuracy and machine stability can basically meet the requirements of project planning. , But there is still much room for improvement in production efficiency. The following mainly introduces how to improve the production efficiency of laser cutting equipment and analyze the design improvements.
The laser cutting equipment for square tube processing is mainly composed of background material processing module, feeding module, feeding module, cutting module, cutting module, panel control module and auxiliary function module. The background material list processing module is mainly CNC machining programming software for the workpiece, which converts the drawing of the workpiece into a cutting file. The loading module is divided into two modes: full-automatic loading and semi-automatic loading. The feeding module is divided into two chuck clamping modes and three chuck clamping modes. The difference between the two modes is that the length of the workpiece is determined which one is used. For long material processing, the three chuck clamping mode is preferred. The cutting module is mainly composed of a cutting head and a laser. There are two types of fiber lasers: carbon fiber and carbon dioxide. Compared with carbon dioxide laser cutters, the cutting range of fiber is relatively narrow. Because of the wavelength, it can only cut metallic materials, and it is not easy for them to be absorbed by non-metals.
