Abstract
Description
Technical Field
[0001] This utility model relates to the field of pipe processing technology, and in particular to a laser cutting machine for pipes. Background Technology
[0002] A laser cutting machine uses a laser emitted from a laser source, which is focused into a high-power-density laser beam through an optical path system. The laser beam irradiates the surface of the workpiece, and as the relative position of the beam and the workpiece moves, a kerf is eventually formed in the material, thus achieving the purpose of cutting. Currently, laser cutting machines are frequently used in the production of pipes.
[0003] Existing pipe laser cutting machines have some shortcomings in use. When cutting pipes, it is often necessary to cut different shapes of cuts, such as bevels or ovals, according to customer requirements. Traditional laser cutting machines can only cut the flat surface of pipes and do not have the ability to rotate the laser cutter at multiple angles to meet different cut shape requirements, which reduces the applicability of laser cutting machines. To address the above problems, an improved and upgraded pipe laser cutting machine is proposed. Utility Model Content

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0024] like Figures 1 to 5 As shown, this embodiment provides a design for a laser cutting machine for pipes, including a processing machine table 1, a support base plate 6 above the processing machine table 1, two positioning structures 5 symmetrically fixed on the upper end of the support base plate 6, and a pipe body 4 inside the positioning structure 5. A support frame 2 is set directly above the processing machine table 1, and a second toothed plate 92 and a second slide rail 93 are respectively fixed on the upper end of the support frame 2.
[0025] An adjustment structure 3 is provided above the support frame 2. The adjustment structure 3 includes a positioning frame 31. A second motor 9 is fixedly installed inside the positioning frame 31. A second gear 91 is fixedly connected to the output end of the second motor 9 and the second gear 91 is meshed with the second rack plate 92. A fixing plate 32 is provided on the front side of the positioning frame 31 and a first stepper motor 34 is provided on the front side of the fixing plate 32. A second limit frame 36 is fixedly connected to the output end of the first stepper motor 34. A second stepper motor 35 is fixedly installed inside the second limit frame 36. A limit clamp 37 is fixedly connected to the output end of the second stepper motor 35. A laser cutting gun 7 is fixedly installed inside the limit clamp 37.
[0026] like Figures 3 to 4 As shown, two limiting blocks 94 are symmetrically fixedly connected to the inner wall of the positioning frame 31, and the limiting blocks 94 are slidably connected to the outer wall of the support frame 2. Two sets of the second motor 9, the second gear 91, the second slide rail 93, and the second rack plate 92 are provided. Another set is provided on the front side of the positioning frame 31. The second motor 9 is fixedly installed on the fixed plate 32. The output end of the second motor 9 is fixedly connected to the second gear 91. The second gear 91 is meshed with the second rack plate 92, and the second rack plate 92 is fixedly installed on the outer wall of the positioning frame 31. The second slide rail 93 is fixedly and symmetrically installed on the outer wall of the positioning frame 31. Two sets of second sliders 95 are symmetrically provided at the bottom of the fixed plate 32, and the second sliders 95 are slidably connected to the outer wall of the second slide rail 93. The first stepper motor 34 is fixedly installed on the first limiting frame 33, and the first limiting frame 33 and the second limiting frame 36 are the same size.
[0027] By setting two sets of second motors 9 to drive the second gear 91 to rotate and move along the direction of the second rack plate 92, and setting the second slider 95 to slide along the direction of the second slide rail 93, it is convenient to adjust the laser cutting gun 7 to move up, down, left and right over multiple distances. At the same time, the first stepper motor 34 and the second stepper motor 35 are set to cooperate to rotate the laser cutting gun 7 at multiple angles, which breaks through the limitations of traditional two-dimensional plane cutting and is easy to adapt to the multi-curved cutting angle of pipes.
[0028] like Figure 5As shown, two sets of first sliders are symmetrically fixed at the bottom of the support base plate 6, and the two sets of first sliders are slidably connected to two first slide rails 83 respectively. The two first slide rails 83 are fixedly installed on the upper end of the processing machine table 1. Two first motors 8 are symmetrically fixed at one end of the support base plate 6. The output end of the first motor 8 is fixedly connected to a first gear 81, and the first gear 81 is meshed with a first rack plate 82. The first rack plate 82 is fixedly installed on one side of one of the first slide rails 83. The positioning structure 5 includes two placement frames 51 fixedly installed on the support base plate 6. Electric push rods 52 are symmetrically fixedly installed on both sides inside the two placement frames 51, and clamping plates 53 are fixedly installed at the output ends of the electric push rods 52. Anti-slip pads 54 are fixedly installed on the outer walls of the two sets of clamping plates 53. The clamping plates 53 are adapted to the size of the pipe body 4.
[0029] By setting the first motor 8 to drive the first gear 81 to rotate and move along the direction of the first rack plate 82, it is easy to move the pipe on the support base plate 6 to the cutting area stably. At the same time, anti-slip pads 54 are set on the outside of the two clamping plates 53 to facilitate relatively stable clamping and positioning of the pipe.
[0030] The working principle and process of this utility model are as follows: First, the laser cutting path of the pipe is preset on the PLC control panel. Then, the operator places the pipe inside the two placement racks 51, and then drives the clamping plate 53 to clamp and position the outer wall of the pipe by driving the two sets of electric push rods 52. At the same time, anti-slip pads 54 are set to facilitate the relative stability of the pipe clamping and fixing, and prevent displacement. After the pipe is fixed, the external power supply is connected, and the first motor 8 drives the first gear 81 to move along the direction of the first rack plate 82. This causes the pipe on the support base plate 6 to slide on the first slide rail 83 using the two sets of first sliders at the bottom, and stably moves the pipe to the area to be cut below the laser cutting gun 7. The movement stops, and then the second motor 8 is driven to move the first gear 81 to move along the direction of the first rack plate 82. The second motor 9 drives the second gear 91 to move along the direction of the second rack plate 92, causing the second slider 95 on the positioning frame 31 to slide along the direction of the second slide rail 93, which facilitates the left and right movement of the laser cutting gun 7. The principle is the same. Another set of second motors 9 drives the second gear 91 to rotate and move along the direction of the second rack plate 92, which facilitates the up and down movement of the laser cutting gun 7 on the fixed plate 32. At the same time, according to the pre-set cutting path, the first stepper motor 34 drives the second limit frame 36 to rotate to a certain angle, and then drives the second stepper motor 35 to drive the laser cutting gun 7 on the limit clamping plate 37 to rotate and move to a certain angle, and then perform precise cutting on the pipe surface, which can adapt to the cutting needs of different curvature radius areas on the pipe surface.
[0031] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
