Laser cutting machine in the construction machinery industry is the main application of plate processing, generally using CO2 laser cutting machine or fiber laser cutting machine.Cutting applications mainly include slender workpiece, more types of hole plate, sheet metal parts reserved process gap, making sheet metal sample and drilling samples.

1. Application in slender workpiece

In addition, because the cutting, laser cutting machine when the heat generated by the more concentrated, small heat affected zone for parts, engineering machinery industry using a laser cutting machine for cutting the workpiece can effectively control the thermal deformation of the workpiece, especially for the requirement of straightness slender workpiece effect is good, when the workpiece length reaches more than 5500 mm, can use cutting machine itself "connection" function to effectively control the workpiece straightness.

2, in the hole more plate parts of the application

Construction machinery industry, laser cutting round hole, in the face of certain thickness, as long as the workpiece hole diameter size requirement is greater than or equal to the corresponding value of the minimum diameter, and the roughness and diameter size requirements within the scope of the cutting machine guarantee ability can use laser direct blanking, save drilling process, improve the labor productivity.For some of the workpiece containing more holes, the use of laser dot function to determine the location of the hole, for the subsequent hole drilling process saves the time to locate the hole, also saves the drilling template production cost, not only improve the production efficiency, but also improve the accuracy of the product.

3. Application in the reserved process gap of sheet metal parts

The process gap reserved for sheet metal parts is also known as the check groove or process hole.The design of process gap in sheet metal production generally has three forms: one is that two or more bending parts are adjacent, as shown in figure 1;The other is that the bending part of a certain edge is completely bent in the direction of length, as shown in figure 2.For the second process gap, the traditional form is shown in figure 2. A ×b rectangle is set aside. If the laser cutting machine is used to cut the slit with a length of a in this position, it is ok.Third form, when the metal sheet bending ends not under bending machine mould support in a dangling position when the workpiece deformation will happen, in this case, you can use the laser cutting machine in the workpiece under the set aside when a slot in order to prevent the artifacts in the bending deformation, which is expected to figure and reserve a slot as shown in figure 3.

4, in the production of plate plate and drilling plate application

Some sheet metal parts in the construction machinery industry, for some irregular shape of the workpiece, in order to improve the accuracy and efficiency of the detection of blanking parts, the use of laser cutting machine to make blanking detection template, such as bulldozer pine on the Angle, excavator bucket rod and movable arm of the big plate;For some of the coils of the workpiece, when the workpiece installation and test need to use and model auxiliary production and testing of the circular arc is consistent, in order to improve the accuracy of workpiece production and detection efficiency, under normal circumstances, these artifacts using laser cutting blanking production model, and using the line of the laser cutting machine on the sample marked arc and straight line, arc plate such as bulldozer, excavator bucket rod and the movable arm bent plate and digging bucket, etc.
