The main application of metal fiber laser cutting machines in the construction machinery industry is sheet metal processing, usually using CO2 metal fiber laser cutting machines or fiber metal fiber laser cutting machines. Cutting applications mainly include slender workpieces, sheet metal parts with a large number of holes, reserved process notches for sheet metal parts, and the production of sheet metal templates and drilling samples.
Application of metal fiber laser cutting machine in slender workpieces
In addition, metal fiber laser cutting machines generate relatively concentrated heat during cutting, resulting in a smaller heat affected zone on the workpiece. The engineering machinery industry can effectively control the thermal deformation of the workpiece by using metal fiber laser cutting machines, especially for slender workpieces that require straightness. When the workpiece length reaches over 5500mm, the “micro connection” function of the cutting machine itself can be used to effectively control the straightness of the workpiece.
Application of metal fiber laser cutting machine in sheet metal parts with more holes
In the engineering machinery industry, metal fiber laser cutting of circular holes can be used for specific plate thicknesses. As long as the diameter size of the workpiece circular hole is required to be greater than or equal to the corresponding minimum diameter value, and the roughness and diameter size requirements are within the guaranteed range of the cutting machine, metal fiber laser cutting can be used directly, eliminating the drilling process and improving labor production efficiency. For some workpieces with a large number of holes, the metal fiber laser dot function is used to determine the position of the holes, saving the time for positioning the holes in the subsequent drilling process and the cost of making drilling templates. This not only improves production efficiency but also improves product accuracy
Application of metal fiber laser Cutting in Reserved Process Notches of Sheet Metal Parts
The process gap reserved for sheet metal parts is also called a crack stop groove or process hole. There are generally three forms of design for process notches in sheet metal production: the first is where two or more bending parts are adjacent, as shown in Figure 1; The second method is to completely bend a certain edge in the length direction, as shown in Figure 2. For the second process gap, the traditional form is shown in Figure 2, leaving a × If a metal fiber laser cutting machine is used to directly cut a slit with a length of a at this position during the cutting of the rectangular shape of b. For some workpieces with higher requirements, a metal fiber laser cutting machine can be used to directly reserve the slit. The third form is that when the two ends of the sheet metal part cannot be supported on the lower mold of the bending machine and are in a suspended position during bending, the workpiece will deform. In this case, a metal fiber laser cutting machine can be used to reserve a cutting seam during workpiece cutting to prevent deformation during bending. The cutting diagram and reserved cutting seam are shown in Figure 3.
