Four major applications of laser cutting machine in construction machinery industry

The main application of laser cutting machine in the construction machinery industry is sheet metal processing, generally using CO2 laser cutting machine or fiber laser cutting machine. Cutting applications mainly include slender workpieces, plate parts with many holes, reserved process gaps for sheet metal parts, making sheet metal templates and drilling samples.

Application of laser cutting machine in slender workpiece

In addition, due to the relatively concentrated heat generated by the laser cutting machine during cutting, the heat-affected zone of the workpiece is small. The use of laser cutting machine in the construction machinery industry to cut the workpiece can effectively control the thermal deformation of the workpiece, especially for slender and slender workpieces that require straightness. The effect of the workpiece is better. 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 in plate parts with many holes

In the construction machinery industry, laser cutting circular holes, when facing a specific plate thickness, as long as the diameter of the workpiece circular hole is greater than or equal to the corresponding minimum diameter, and the roughness and diameter are within the guaranteed capacity of the cutting machine. All can use the laser to directly cut the material, eliminating the drilling process and improving the labor production efficiency. For some workpieces with many 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 drilling process of the hole, and also saves the production cost of the drilling template, which not only improves the production efficiency, And improve the accuracy of the product.

Application of Laser Cutting in Reserving Process Gap of Sheet Metal Parts

The process gap reserved for sheet metal parts is also called crack relief groove or process hole. There are generally three forms of design of process gaps in sheet metal production: the first is that two or more bending parts are adjacent, as shown in Figure 1; the second is that the bending part of a certain edge is completely lengthwise. Bend, as shown in Figure 2. For the second process gap, the traditional form is shown in Figure 2, and a rectangle of a × b is reserved. If a laser cutting machine is used to cut a slot with a length of a directly at this position, for some requirements For taller workpieces, the laser cutting machine can be used to directly reserve the form of kerf. The third form, when the two ends of the sheet metal part cannot be supported on the lower die of the bending machine and is in a suspended position, the workpiece will be deformed. In this case, the laser cutting machine can be used to pre-empt the workpiece A slit is reserved to prevent the workpiece from being deformed during bending. The blanking diagram and reserved slit are shown in Figure 3.

Application of Laser Cutting in Making Sheet Metal Templates and Drilling Templates

For some sheet metal parts in the construction machinery industry, for some workpieces with irregular shapes, in order to improve the accuracy and efficiency of the detection of blanking parts, a laser cutting machine is used to make blanking detection samples, such as the support angle on the bulldozer ripper, the excavator stick And the big head plate on the boom, etc.; for some coiled workpieces, it is necessary to use a template that matches the arc to assist in the production and inspection of the workpiece. In order to improve the accuracy of workpiece production and the efficiency of inspection, usually Next, use laser cutting and blanking to produce the templates of these workpieces, and use the scribing function of the laser cutting machine to mark the boundaries of arcs and straight edges on the template, such as the arc plate of bulldozers, the sticks of excavators and the moving parts. Bending plate of arm and bucket, etc.
