Description

Technical Field

[0002] Laser cutting is the process of focusing the laser emitted from a laser into a high-power density laser beam through an optical path system. The laser beam is irradiated onto the surface of the workpiece, causing the workpiece to reach its melting point or boiling point. At the same time, high-pressure gas coaxial with the beam blows away the molten or vaporized metal. As the relative position of the beam and the workpiece moves, a cut is eventually formed in the material, thereby achieving the purpose of cutting.

[0003] The laser cutting machine is mainly composed of a base plate, a clamping plate, a laser cutting head and a movable frame. When in use, first place the material to be cut on the clamping plate of the device, set the laser power, cutting speed, gas pressure and other parameters according to the cutting material and requirements, and after confirming that the cutting parameters and materials are fixed correctly, start the cutting program for cutting processing.

[0032] The regulating unit includes a vertical plate 22 fixedly arranged on the bearing plate 21, and adjusting rods 45 are fixedly arranged on the side walls at both ends of the shell 4. A sliding groove 221 is provided on the vertical plate 22, and the adjusting rod 45 is slidably connected with the sliding groove 221. A bracket 1 42 is fixedly arranged on the lower end surface of the shell 4, and a bracket 2 43 is fixedly arranged on the side wall of the shell 4.

[0033] Reference Figure 1-Figure 3 Four mutually parallel support columns 11 are fixedly arranged on the base plate 1, and each support column 11 is evenly arranged at each corner of the base plate 1. An anti-skid plate 12 is fixedly arranged on the bottom end of the support column 11. By arranging the support columns 11 on the base plate 1, the support function of the entire device is realized. At the same time, each support column 11 is arranged at the corner of the base plate 1 so that each support column 11 can be evenly stressed during the support process, thereby avoiding damage to the support column 11 due to uneven stress during the support process. At the same time, the anti-skid plate 12 arranged on the bottom end of the support column 11 can increase the friction between the device and the ground, thereby avoiding the device from slipping during use.

[0034] Reference Figure 2-Figure 4 A positioning frame is slidably provided on the guide plate 3, and a guide rod 311 is fixedly provided on the positioning frame. The laser cutting head 31 is slidably provided on the guide rod 311. The position of the laser cutting head 31 is fixed by the positioning frame provided on the guide plate 3, and the laser cutting head 31 is controlled to move laterally along the guide plate 3.

Through the slide plate 44 arranged in the shell 4, when the staff controls the tilt of the shell 4, the rising shell 4 can drive the connecting wire 531 to move, and the moving connecting wire 531 can drag the positioning plate 2 53 outward, thereby controlling the horizontal height of the lowering loading plate 6. When the shell 4 is in a vertical state, the positioning plate 2 53 can control the two regulating plates 52 to rotate and lift the loading plate 6, and the loading plate 6 is used to position and process the material to be processed.

[0037] Reference Figure 6-Figure 8 A telescopic column 411 is slidably arranged in the cylinder 41, a disc 412 is slidably arranged in the cylinder 41, a spring 413 is fixedly arranged between the disc 412 and the telescopic column 411, and a compression chamber 414 is formed between the disc 412 and the bottom end of the cylinder 41. By means of the telescopic column 411 arranged in the cylinder 41, when the cut metal falls down and hits the telescopic column 411 of the device, part of the pressure acts on the spring 413 of the device, and the spring 413 can dissipate part of the elastic force in the compression chamber 414 through the disc 412, thereby reducing the rebound force of the telescopic column 411.

[0038] Reference Figure 1-Figure 3 The slide groove 221 is arranged in an arc shape, and the two slide grooves 221 in the same vertical plane are arranged in a mirror image. By setting the slide groove 221 in an arc shape, the movement trajectory and movement range of the control shell 4 are realized, the device is prevented from getting stuck during use, and the convenience of the device during use is improved.

[0039] Reference Figure 5-Figure 7 A rotating shaft is fixedly provided on both the bracket 1 42 and the bracket 2 43, and the rotating shaft is fitted with the side wall of the guide groove 25. By setting the rotating shaft between the bracket 1 42 and the bracket 2 43, when the shell 4 is tilted, the rotating shaft fitted in the guide groove 25 can prevent the shell 4 from shaking when it is tilted, thereby improving the overall stability of the device.

[0040] Reference Figure 1-Figure 7The sum of the lengths of the two regulating plates 52 is less than the vertical height of the support plate 23, and each positioning plate 5 is evenly arranged on the upper end surface of the base plate 1. By setting the size relationship between the regulating plates 52 and the support plate 23, it is ensured that the device can operate normally, that is, the shell 4 can maintain a stable working state and can complete the laser cutting operation of the frame-type metal.

[0041] Reference Figure 1 , Figure 5 and Figure 7 The length of the long board 441 is not less than the width of the inner wall of the shell 4, and the long board 441 and the shell 4 penetrate the shell 4. By setting the length relationship of the long board 441, it is ensured that the slide plate 44 can operate normally.

[0042] The specific solution is as follows: when using the device, the staff first moves the device to a suitable position, and realizes the support function of the entire device through the various support columns 11 on the bottom plate 1 of the device. When the staff performs laser cutting on the frame-shaped metal, the staff places the object to be processed on the device shell 4, and then cuts by adjusting the position of the laser cutting head 31. The frame-shaped scrap metal after cutting will collapse due to the lack of support in the middle position. The collapsed metal falls down and hits the telescopic column 411 of the device. At this time, part of the pressure acts on the spring 413 of the device, and the spring 413 can transfer part of the elastic force through the circular The disk 412 dissipates in the compression chamber 414, reducing the rebound force of the telescopic column 411, thereby avoiding the rebound of scrap metal, protecting the laser cutting head 31 and improving the operating efficiency of the device. When processing some wide and thick metal plates, the staff controls the outer shell 4 to tilt and rise through the control console. The rising outer shell 4 can drive the connecting wire 531 to move, and the moving connecting wire 531 can drag the positioning plate 2 53 outward, thereby achieving the horizontal height of the lowering of the carrier plate 6. When the outer shell 4 is in a vertical state, the positioning plate 2 53 can control the two regulating plates 52 to rotate and lift the carrier plate 6. At this time, the carrier plate 6 positions the material to be processed.
