Laser cutting machine is the main application of sheet metal processing in construction machinery industry, and CO2 laser cutting machine or fiber laser cutting machine is generally used. Cutting applications mainly include slender workpieces, multi-type orifice plates, reserved process clearance for sheet metal parts, making sheet metal samples and drilling samples.

1. Application on slender workpieces

In addition, due to the more concentrated heat generated by cutting and laser cutting machines, small parts in the heat-affected zone, the use of laser cutting machines to cut workpieces in the construction machinery industry can effectively control the thermal deformation of workpieces, especially for straightness requirements. Well, when the length of the workpiece reaches more than 5500 mm, the straightness of the workpiece can be effectively controlled by using the "joint" function of the cutting machine itself.

2. Application of multi-plate parts in holes

In the construction machinery industry, laser cutting circular holes, in the face of a certain thickness, as long as the diameter of the workpiece hole is required to be greater than or equal to the corresponding value of the minimum diameter, and the roughness and diameter requirements can be used within the scope of the guarantee of the laser cutting machine. Cutting materials saves the drilling process and improves labor productivity. Some workpieces contain more holes, use the laser point function to determine the position of the hole, save time to locate the hole in the subsequent hole drilling process, and also save the production cost of the drilling template, not only improve production efficiency, but also improve the accuracy of the product.

3. Applied to the reservation of the process gap of sheet metal parts

The process clearance reserved for sheet metal parts is also called check groove or process hole. The design of the gap in the sheet metal production process usually has three forms: one is that two or more curved parts are adjacent, as shown in Figure 1, and the other is the direction of the complete bending length of the edge of a certain curved part, such as Figure 2 shows. For the second process gap, the traditional form is shown in Figure 2. Leave an A x b rectangle. If a laser cutter is used to cut a slit of length a at this position, it is possible. The third form, when the bending end of the metal plate is not lower than the bending machine die support in a suspended position when the deformation of the workpiece will occur, in this case, you can use the laser cutting machine to reserve grooves in the workpiece in order to prevent the workpiece from bending To deform, project the graph and reserve a slot, as shown in Figure 3.

4. Application of plates and drilled plates in production

For some sheet metal parts in the construction machinery industry, for some irregular-shaped workpieces, in order to improve the accuracy and efficiency of the blanking part of the detection, use a laser cutting machine to blank the detection template, such as loose corners of bulldozers, excavator sticks and moving parts. The large plate of the arm, for some coil workpieces, when the workpiece installation and testing needs to be used and the arc of the model-assisted production and testing is consistent, in order to improve the accuracy of the workpiece production and detection efficiency, under normal circumstances, these workpieces use laser Cut blanks to produce models, and use laser cutting machines on samples for arcs and straight lines, arc plates such as bulldozers, excavator sticks and booms, curved plates and buckets, etc.
