Description

Technical Field

[0001] The invention relates to the technical field of multifunctional laser cutting machines, in particular to a multifunctional four-in-one laser cutting machine. Background Art

[0002] A multifunctional laser cutting machine is a laser processing equipment that integrates multiple functions. It can perform various types of laser cutting processing tasks, thereby adapting to the positioning, installation and cutting processing requirements of different types of workpieces. When processing workpieces through a multifunctional laser cutting machine, the workpiece is generally positioned in the processing area first, and then the workpiece is cut, opened or sloped according to the processing requirements. The corresponding laser cutting processing such as bevel cutting or slope cutting is performed.

[0003] However, the traditional multifunctional laser cutting machine has the following problems in cutting workpieces: 1. In the prior art, when cutting pipes, the multifunctional laser cutting machine generally positions and loads the pipes by clamping and conveying at one end and supporting at the other end. If the pipe to be processed is long, the part to be processed on the pipe will lack sufficient support, which will cause the part to be deformed due to the weight of the pipe itself, thus affecting the overall cutting accuracy of the pipe; 2. When laser cutting plate or profile workpieces, such workpieces are generally placed and positioned on the nail plate on the surface of the nail bed. During the cutting process, the high-temperature debris dropped from the workpiece will The surface of the nail plate near the cutting area of ​​the nail bed will be attached with high-temperature debris after long-term use, which will greatly affect the flatness of the surface of the nail plate, thereby affecting the stability of the placement and positioning of the workpiece to be processed, and further affecting the accuracy of the overall cutting process of the workpiece; 3. During the long-term use of the nail bed, the high-temperature debris generated by laser cutting of the workpiece will usually adhere to the surface of the nail plate in the area where cutting is often performed, resulting in a shorter service life of the nail plate in this area, resulting in the replacement of the entire nail bed due to the unusable nail plates in some areas, which greatly affects the overall service life of the nail bed, and at the same time causes a certain degree of material waste, leading to an increase in the overall production and processing costs.

At the same time, the electric push rod 52 can be used to drive the side baffle plate 53 to adjust left and right to limit the workpiece laterally, so as to ensure that the workpiece can be stably placed, thereby ensuring the accuracy and consistency of the laser cutting processing of the workpiece.
