With the rapid development and application of laser science and technology research, laser cutting technology has now developed into one of the most critical technologies in the machinery manufacturing industry. The main application of laser cutting machines in the construction machinery industry is sheet metal processing, and CO2 laser cutting machines and fiber laser cutting machines are generally used. Let Leapion Laser share what are the specific applications of laser cutting machines in the construction machinery industry?
The application of laser cutting technology in the application engineering machinery industry mainly includes: slender workpieces, plate parts with more holes, reserved process gaps for sheet metal parts, production of sheet metal templates and drilling samples. Let's take a closer look:
Because of the concentrated heat generated by the laser cutting machine during cutting, the heat-affected zone on the workpiece is small. The laser cutting machine in the construction machinery industry can effectively control the thermal deformation of the workpiece, especially for the thin and long workpieces that require straightness. Preferably, when the length of the workpiece reaches 5500mm or more, the "micro-connection" function of the cutting machine can be used to effectively control the straightness of the workpiece.
In the construction machinery industry, laser cutting round holes, when facing a specific plate thickness, as long as the diameter of the round hole of the workpiece is greater than or equal to the value of the corresponding minimum diameter, and the roughness and diameter are within the guaranteed capacity of the cutting machine The laser can be used for direct blanking, eliminating the need for drilling procedures and improving labor productivity. For some workpieces with many holes, the laser dot function is used to determine the position of the hole, which saves the time for positioning holes for the subsequent hole drilling process, and also saves the production cost of the drilling template, which not only improves the production efficiency, And the accuracy of the product is improved.
The process gap reserved for sheet metal parts is also called crack arrest groove or process hole. In sheet metal production, the design of process gaps generally has three forms: the first is that two or more bending parts are adjacent, as shown in Figure 1.
The second is that the bent part of a certain edge is completely bent in the length direction, as shown in Figure 2. For the second process gap, the traditional form is shown in Figure 2, leaving a × b rectangle. If you use a laser cutting machine to cut a slit of length a directly at this position when cutting, it is required for some requirements For relatively tall workpieces, the laser cutting machine can be used to directly reserve the form of slitting.
In the third form, when the two ends of the sheet metal part cannot be supported on the lower die of the bending machine in a suspended position, the workpiece will deform. In this case, the laser cutting machine can be used to predict the workpiece Leave a slit to prevent the workpiece from being deformed during bending. The blanking diagram and the reserved slit are shown in Figure 3.
In the construction machinery industry, some sheet metal parts, for some irregularly shaped workpieces, in order to improve the accuracy and efficiency of detecting the blanking parts, laser cutting machines are used to make blanking detection templates, such as the support angle on the bulldozer ripper, and the bucket rod of the excavator. And the big headboard on the boom, etc.;
For some rolled-formed workpieces, it is necessary to use a template that matches the arc to assist in the production and inspection of the workpiece during the production and inspection of the workpiece. In order to improve the accuracy of workpiece production and the efficiency of inspection, usually, laser cutting is used for production. The prototypes of these workpieces, and use the marking function of the laser cutting machine to mark the boundaries of arcs and straight edges on the prototypes, such as the curved plate of the bulldozer, the arm of the excavator, the curved plate of the boom, and the bucket.
In recent years, the scope of laser applications has been continuously expanded, and laser cutting technology accounts for nearly 60% of them, and has developed into an important field of laser applications. Laser cutting equipment is constantly updated, cutting materials are more diversified, and manufacturing processes are more complicated.
