Description

Technical Field

[0001] The present invention relates to the technical field of metal laser cutting, in particular to a large-format metal laser cutting machine with automatic positioning. Background Art

[0002] Metal laser cutting utilizes a high-powered laser beam to cut metal materials. This process achieves precise cutting by focusing the laser beam on the metal surface, rapidly heating the metal to its melting point. Laser cutting offers numerous advantages, including high cutting accuracy, smooth cuts, and a minimal heat-affected zone. It is suitable for a wide variety of metal materials, including stainless steel, aluminum, copper, and carbon steel.

[0003] A metal laser cutting machine is a device specifically designed for cutting metal materials, using a high-powered laser beam to precisely cut metal. The core principle of a laser cutting machine is to illuminate the metal surface with a high-energy laser beam, causing the metal to rapidly melt or evaporate in a certain area, thereby achieving high-precision cutting. However, a metal laser cutting machine generates a large amount of iron filings on the cutting surface during cutting. After cutting one workpiece, the cutting surface must be cleaned before the next workpiece can be cut. During this cleaning period, cutting cannot be performed, significantly affecting processing efficiency.

[0004] To solve the above problems, we proposed a large-format metal laser cutting machine with automatic positioning. Summary of the Invention

[0005] The purpose of the present invention is to solve the problems in the background technology and to propose a large-format metal laser cutting machine with automatic positioning.

[0007] In the above-mentioned large-format metal laser cutting machine with automatic positioning, a two-way threaded rod is connected to the left and right inner walls of the U-shaped table for common rotation, and a limit rod is fixedly connected to the left and right inner walls of the U-shaped table. Two fixed blocks are threadedly sleeved on the two-way threaded rod, and the two fixed blocks are slidably sleeved on the limit rod. The front ends of the two fixed blocks are fixedly connected to a moving rod, and the opposite ends of the two moving rods are fixedly connected to several fixed plug rods. A second motor is provided on the U-shaped table to drive the two-way threaded rod to rotate.

[0008] In the aforementioned large-format metal laser cutting machine with automatic positioning, a plurality of fixing slots are provided on both the left and right ends of the cutting platform.

[0009] In the above-mentioned large-format metal laser cutting machine with automatic positioning, a movable U-shaped frame is slidably connected to the two first electric slide rails, a second electric slide rail is provided on the movable U-shaped frame, a movable slider is slidably connected to the second electric slide rail, and a cutting assembly is provided at the lower end of the movable slider.

[0010] The cam is fixedly mounted on the base plate of the machine and is provided with a plurality of movable members, each of which is connected to the movable member by a plurality of movable members, and the movable member is connected to the movable member by a plurality of movable members.

[0011] In the above-mentioned large-format metal laser cutting machine with automatic positioning, both left and right ends of the reciprocating rotating rod are fixedly connected with nozzles, and water pipes are connected between the two nozzles and the water tank.

[0012] In the above-mentioned large-format metal laser cutting machine with automatic positioning, third electric slide rails are provided on the left and right inner walls of the U-shaped support leg, and a movable plate is slidably connected to the two third electric slide rails. A connecting plate is fixedly connected to the movable plate, and a rectangular frame is fixedly connected to the front end of the connecting plate.

[0013] Compared with existing technologies, the advantages of this large-format metal laser cutting machine with automatic positioning are:

[0014] 1. When the lower end of the cutting platform is being cleaned, the upper end of the cutting platform can be used for cutting at the same time. After the workpiece is cut, the cutting platform can be turned over to continue the operation. The cutting operation can be carried out while the cutting platform is being cleaned, which greatly improves the processing efficiency.

[0015] 2. The reciprocating rotating rod rotates back and forth to drive the two nozzles to swing back and forth. When swinging back and forth, the two nozzles spray water to flush the lower end of the cutting platform. The reciprocating swing increases the flushing range of the two nozzles, and the rectangular frame blocks the splashing water to prevent it from splashing to other places.
