The main application of laser cutting machine in the engineering machinery industry is sheet processing. Generally, CO2 laser cutting machine or fiber laser cutting machine is used. Cutting applications mainly include slender workpieces, sheet metal parts with a large number of holes, sheet metal parts with reserved process gaps, sheet metal prototypes and drilling samples.

Application of laser cutting machine for slender workpiece

In addition, laser cutting machine has a relatively concentrated heat generated during cutting, and has a relatively small heat-affected zone on the workpiece. The laser cutting machine used in the construction machinery industry can effectively control the thermal deformation of the workpiece, especially for the slenderness requiring straightness The effect of the workpiece is good. When the length of the workpiece reaches more than 5500mm, the "micro connection" function of the cutting machine itself can be used to effectively control the straightness of the workpiece.

Application of laser cutting machine for sheet metal parts with many holes

In the engineering machinery industry, when laser cutting circular holes, when facing a specific plate thickness, as long as the diameter of the workpiece's circular hole is required to be greater than or equal to the corresponding minimum diameter, and the roughness and diameter are required to be within the guarantee of the cutting machine All can be cut directly by laser, eliminating the drilling process and improving labor production efficiency. For some workpieces with a lot of holes, the laser spotting function is used to determine the position of the hole, which saves the time of positioning the hole for the subsequent hole drilling process, and saves the cost of making the drilling template, which not only improves the production efficiency, And it improves the accuracy of the product.

The application of laser cutting in the reserved technological notch of sheet metal parts

The technological notch reserved for sheet metal parts is also called crack stop groove or technological hole. In sheet metal production, there are generally three forms of process notch design. If the laser cutting machine is used to cut the slit with length of a directly at this position during cutting, the laser cutting machine can be used to directly reserve the slit for some workpieces with high requirements. In the third form, when the two ends of the sheet metal parts cannot be supported on the lower die of the bending machine in the suspended position, the workpiece will be deformed. In this case, a cutting seam can be reserved when the laser cutting machine is used to cut the workpiece to prevent the deformation of the workpiece during bending.

The application of laser cutting in making sheet metal sample plate and drilling sample plate

In the construction machinery industry, for some irregular shaped workpieces, in order to improve the accuracy and efficiency of the inspection of the blanking parts, the laser cutting machine is used to make blanking inspection samples, such as the support angle on the bulldozer scarifier, the large head plate on the excavator stick and the boom, etc.; for some workpieces formed by rolling plates, it is necessary to use the one that coincides with the arc during the production and inspection of workpieces In order to improve the accuracy and efficiency of the production and detection of workpieces, the template is usually produced by laser cutting and blanking, and the boundaries of arc and straight edge are marked on the template by the scribing function of laser cutting machine, such as the arc plate of bulldozer, the curved plate of bucket bar and boom of excavator, and the digging bucket.
