[0036] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0037] Embodiment 1

[0038] like Figures 1 to 11As shown, a cutting device for steel processing described in an embodiment of the present invention includes a support base 11, a fixed block 1 is slidably arranged on the support base 11, a plurality of displacement sliders 12 are slidably connected to the inner top of the support base 11, a guide rack 13 is fixedly connected to the bottom of each displacement slider 12, and the guide rack 13 is symmetrically fixedly connected to the bottom of both ends of the displacement slider 12, the outer surface of the support base 11 is symmetrically rotatably connected to a transmission gear 14, and the two transmission gears 14 are meshed with the guide rack 13, the top of the fixed block 1 is symmetrically rotatably connected to a displacement rod 15, and the fixed block 1 between the two displacement rods 15 is internally fixedly connected A support rod 16 is connected, and a displacement block 17 is slidably connected to the surface of the support rod 16. Two displacement rods 15 penetrate the displacement block 17 and are threadedly connected to the displacement block 17. An electric telescopic rod 18 is fixedly connected to the bottom of the displacement block 17. A laser spray gun 19 is rotatably connected to the bottom output end of the electric telescopic rod 18. A high-pressure air gun 110 is fixedly connected to one side of the laser spray gun 19. A clamping assembly is provided on the top of each displacement slider 12. The clamping assembly is used to clamp the H-shaped steel, and when the clamping position and the cutting position overlap, the H-shaped steel thereon can be displaced. The clamping assembly clamps and displaces the H-shaped steel thereon through the displacement of the displacement slider 12.

[0039] Specifically, the existing cutting equipment for steel processing still has some problems in practical use. When the existing cutting equipment is in use, when the H-shaped steel clamped by the clamping device needs to be cut, due to the fixation of the H-shaped steel by the clamping device, it is necessary to reset the clamping device and move the H-shaped steel so that the position where the H-shaped steel needs to be cut does not contact the clamping device. This operation takes a lot of time, reduces the production efficiency of the H-shaped steel processing, and increases the processing cost.

[0040] Therefore, the present invention solves this problem by setting a corresponding structure, placing the bottom between the two sides of the H-shaped steel on the clamping device through a crane, so that the two sides of the H-shaped steel cover the top of the clamping device, and expanding through the outward displacement of the clamping device, thereby fixing the H-shaped steel on its top;

[0041] In actual use, a motor can be installed inside the support base 11 to drive the transmission gear 14 to rotate, and the rotation of the transmission gear 14 drives the guide rack 13 to move, and then the displacement of the guide rack 13 drives the displacement slider 12 thereon to slide on the support base 11, and the displacement of the displacement slider 12 drives the clamping device to move, so that the H-shaped steel on the clamping device moves together with the clamping device;

[0042] When the H-shaped steel on the clamping device is displaced to below the top of the fixed block 1, the external motor on the transmission gear 14 is turned off to stop the clamping device from being displaced, thereby stopping the H-shaped steel on the clamping device from moving, and starting the external motor on the displacement rod 15 to drive the displacement rod 15 to rotate through the output end of the external motor on the displacement rod 15. Since the displacement rod 15 is threadedly connected to the displacement block 17, the displacement block 17 is displaced by the rotation of the displacement rod 15, and then the displacement block 17 is displaced on the support rod 16 through the displacement of the displacement block 17, so that the electric telescopic rod 18 fixed on the displacement block 17 is displaced together with the displacement block 17. When the displacement block 17 is displaced to the required cutting position, the electric telescopic rod 18 is started to extend the electric telescopic rod 18, and the extension of the electric telescopic rod 18 drives the laser spray gun 19 on the electric telescopic rod 18 to move downward together with the extension of the electric telescopic rod 18, so that the nozzle of the laser spray gun 19 is close to the H-shaped steel. The outer surface, at this time, the laser spray gun 19 and the high-pressure air gun 110 are started, and the laser beam ejected by the laser spray gun 19 cuts the H-shaped steel below the nozzle of the laser spray gun 19, and the high-pressure gas ejected by the electric telescopic rod 18 blows away the splashes generated by the laser beam cutting the H-shaped steel. When cutting both sides of the H-shaped steel, the motor external to the laser spray gun 19 is started at this time, and the laser spray gun 19 is driven to rotate by the output end of the motor external to the laser spray gun 19, so that the nozzle of the laser spray gun 19 is kept vertical to one side of the H-shaped steel. At this time, the laser spray gun 19 and the electric telescopic rod 18 are started, and one side of the H-shaped steel is cut by extending the electric telescopic rod 18, and the other side of the H-shaped steel is repeated. In this process, the processing and cutting of the H-shaped steel are completed by the displacement of the displacement block 17, the extension of the electric telescopic rod 18, the steering of the laser spray gun 19 and the movement of the clamping device, thereby producing the desired product;

[0043] When the H-beam at the clamping position of the clamping device needs to be cut, the H-beam is displaced at the top of the clamping device toward the direction close to the laser spray gun 19 through the clamping device, thereby solving the problem that when the H-beam at the clamping position of the clamping device needs to be cut, the clamping device needs to be reset and the H-beam needs to be displaced due to the fixation of the H-beam by the clamping device, so that the position where the H-beam needs to be cut does not contact the clamping device, thereby improving the production efficiency of H-beam processing and reducing the processing cost.

[0044] like Figure 2 As shown, in this embodiment, a displacement thread groove is provided on the displacement rod 15 , and a displacement thread is provided inside the displacement block 17 . The displacement thread on the displacement block 17 matches the shape of the displacement thread groove on the displacement rod 15 .

[0045] Specifically, the displacement thread on the displacement block 17 matches the shape of the displacement thread groove on the displacement rod 15, so that when the displacement rod 15 rotates, the displacement thread on the displacement block 17 moves along the direction of the displacement thread groove on the displacement rod 15, thereby causing the displacement block 17 to displace on the displacement rod 15 as the displacement rod 15 rotates.

[0046] like Figure 1 , Figures 3 to 5 As shown, the clamping assembly of this embodiment includes a fixed rod 111, the fixed rod 111 is fixedly connected between the two ends of the support base 11, and a moving rod 112 is slidably connected between the two ends of the support base 11. The surface of the fixed rod 111 is slidably connected to a limited block 113, and the surface of the moving rod 112 is slidably connected to a moving block 114. The displacement slider 12 passes through the limited block 113 and the moving block 114. The inner walls of both ends of the support base 11 are provided with sliding grooves 21. The two ends of the moving rod 112 are slidably connected to the moving block 114. A guide rod 23 is rotatably connected between the inner walls of the sliding groove 21, and a guide slider 24 is threaded on the guide rod 23. The guide slider 24 is slidably connected in the sliding groove 21. A compression spring 25 is fixedly connected in the guide slider 24, and a resistance block 26 is fixedly connected at one end of the compression spring 25 away from the bottom of the guide slider 24. The resistance block 26 is slidably connected in the guide slider 24, and the resistance block 1 22 is located on the movement trajectory of the resistance block 26.

[0047] Specifically, the bottom between the two sides of the H-shaped steel is placed on the top of the limit block 113 and the moving block 114 by a crane, so that the top of the limit block 113 and the moving block 114 is covered between the two sides of the H-shaped steel. At this time, the guide rod 23 is driven to rotate. Since the guide rod 23 is threadedly connected with the guide slider 24, the guide slider 24 is driven to slide and connect in the sliding groove 21 through the rotation of the guide rod 23, so that the compression spring 25 in the guide slider 24 and the resistance block 26 move together with the guide slider 24, and the resistance block 26 moves together with the guide slider 24. In the process of moving with the guide slider 24, since the second contact block 26 is slidably connected in the guide slider 24, the second contact block 26 in the guide slider 24 contacts with the first contact block 22 and drives the first contact block 22 to move together, thereby driving the motion block 114 fixed to the first contact block 22 to move together with the first contact block 22. Since the limit block 113 is fixedly arranged, when the motion block 114 moves, it moves at the bottom of the H-shaped steel under the limiting action of the limit block 113, thereby clamping and fixing the H-shaped steel.

[0048] When the moving block 114 contacts the inner wall of one side of the H-shaped steel, the H-shaped steel is clamped and fixed under the action of the limit block 113 and the moving block 114. At this time, the contact block 1 22 is stationary. When the guide slider 24 continues to move, the contact block 26 contacts the contact block 1 22 under the action of the displacement of the guide slider 24, so that the contact block 26 slides downward in the guide slider 24 and elastically compresses the compression spring 25 until the contact block 26 passes through the contact block 1 22. The compression spring 25 begins to release elastically, so that the contact block 26 slides upward in the compression spring 25 until it returns to the initial position.

[0049] By contracting the second resistance block 26, the moving block 114 contacts the inner wall of one side of the H-shaped steel. The second resistance block 26 no longer pushes the first resistance block 22, so that the moving block 114 remains stationary, and the limit block 113 and the moving block 114 adaptively clamp the H-shaped steel, preventing deformation of both sides of the H-shaped steel due to excessive clamping, thereby ensuring the appearance consistency of the H-shaped steel.

[0050] like Figure 1 , Figures 3 to 5 As shown, the limit blocks 113 and the moving blocks 114 described in this embodiment are provided with several groups, and each group of limit blocks 113 and moving blocks 114 corresponds one-to-one to the displacement slider 12, the resistance block 22 slides in the sliding groove 21, the guide rod 23 has a guide thread groove on its surface, and the guide slider 24 has a guide thread inside, and the guide thread in the guide slider 24 matches the shape of the guide thread groove on the guide rod 23.

[0051] Specifically, each displacement slider 12 is provided with a limit block 113 and a moving block 114; the resistance block 22 slides in the sliding groove 21, so that the resistance block 22 is located on the movement trajectory of the resistance block 2 26; the guide thread in the guide slider 24 matches the shape of the guide thread groove on the guide rod 23, so that when the guide rod 23 rotates, the guide thread in the guide slider 24 moves along the trajectory of the guide thread groove on the guide rod 23, so that the guide slider 24 slides on the guide rod 23.

[0052] like Figures 6 to 9As shown, the clamping assembly of this embodiment also includes a transmission rack 27, and the transmission rack 27 is fixedly connected to the top of the displacement slider 12. A movement groove 28 is provided in the movement block 114, and a transmission gear 29 is rotatably connected in the movement groove 28. The transmission gear 29 is meshed with the transmission rack 27. A rotating bevel gear rod 210 is fixedly connected to one side of the transmission gear 29, and a transmission bevel gear rod 211 is rotatably connected in the movement groove 28. The rotating bevel gear rod 210 is meshed with the transmission bevel gear rod 211. The surface of the transmission bevel gear rod 211 is rotatably connected with a speed increasing gear 212, and a limiting groove 213 is provided between the speed increasing gear 212 and the transmission bevel gear rod 211. A rotating shaft 214 is fixedly connected in the limiting groove 213 in the transmission bevel gear rod 211, and a resistance plate 215 is rotatably connected to the surface of the rotating shaft 214. A return spring 216 is fixedly connected to one side of the resistance plate 215, and one end of the return spring 216 away from the resistance plate 215 is fixedly connected to the inner wall of the limiting groove 213 in the transmission bevel gear rod 211.

[0053] Specifically, when the motion block 114 is displaced together with the abutment block 1 22, the motion block 114 slides on the displacement slider 12. Since the transmission rack 27 is fixed on the displacement slider 12 and the displacement slider 12 is meshed with the transmission gear 29, as the motion block 114 is displaced, the transmission gear 29 starts to rotate under the action of the transmission rack 27, thereby driving the rotating bevel gear rod 210 fixed thereon to rotate together. Since the rotating bevel gear rod 210 is meshed with the transmission bevel gear rod 211, the rotation of the rotating bevel gear rod 210 drives the transmission bevel gear rod 211 to rotate together, so that the transmission bevel gear rod 211 rotates in the motion groove 28.

[0054] When the moving block 114 moves outward together with the abutment block 22, during this process, when the transmission bevel gear rod 211 rotates, the transmission bevel gear rod 211 will drive the rotating shaft 214 in the limiting groove 213 to rotate together with the transmission bevel gear rod 211, so that the abutment plate 215, under the action of the displacement of the rotating shaft 214 and the transmission bevel gear rod 211, is fixed by the return spring 216 and abuts against the inner wall of the limiting groove 213 in the speed-increasing gear 212. At this time, as the transmission bevel gear rod 211 continues to rotate, the abutment plate 215 abuts against the inner wall of the limiting groove 213 in the speed-increasing gear 212, with the rotating shaft 214 as the axis. The return spring 216 is elastically compressed, so that the contact plate 215 is pressed into the limit groove 213 in the transmission bevel gear rod 211, until the contact plate 215 enters the limit groove 213 in the next speed-increasing gear 1 212. At this time, the contact plate 215 does not conflict with the limit groove 213 in the speed-increasing gear 1 212. Under the action of the elastic release of the return spring 216, the contact plate 215 rotates with the rotating shaft 214 as the axis in the direction away from the return spring 216 until the contact plate 215 returns to the initial position, and so on, so that the speed-increasing gear 1 212 is stationary when the transmission bevel gear rod 211 rotates;

[0055] When the H-shaped steel at the clamping position of the limit block 113 and the moving block 114 needs to be cut, the moving block 114 moves inward together with the resistance block 1 22, and the transmission gear 2 29 rotates in the opposite direction, so that the rotating bevel gear rod 210 rotates in the opposite direction together with the transmission gear 29, thereby driving the transmission bevel gear rod 211 to rotate in the opposite direction. During the reverse rotation of the transmission bevel gear rod 211, the support base 11 drives the rotating shaft 214 in the limit groove 213 to rotate together with the transmission bevel gear rod 211, thereby causing the resistance plate 215 to move with the displacement of the rotating shaft 214 and the transmission bevel gear rod 211 through the reset spring 216. The contact plate 215 is fixed and contacts the inner wall of the inner limit groove 213 of the speed increasing gear 212. At this time, as the transmission bevel gear rod 211 continues to rotate, the contact plate 215 rotates in the direction away from the return spring 216 with the rotating shaft 214 as the axis under the contact of the inner wall of the inner limit groove 213 of the speed increasing gear 212, and elastically stretches the return spring 216, so that the contact plate 215 is stationary under the contact between the inner wall of the inner limit groove 213 of the speed increasing gear 212 and the inner wall of the inner limit groove 213 of the transmission bevel gear rod 211, and then drives the speed increasing gear 212 to rotate together with the transmission bevel gear rod 211 through the rotation in the direction of the transmission bevel gear rod 211.

[0056] like Figures 7 to 9 As shown, the shape of the second transmission gear 29 in this embodiment matches the shape of the motion slot 28 , and the shape of the rotating bevel gear rod 210 matches the shape of the motion slot 28 .

[0057] Specifically, because the shapes of the transmission gear 29 and the rotating bevel gear rod 210 match the shape of the motion groove 28, the transmission gear 29 and the rotating bevel gear rod 210 are limited in the motion groove 28, so that the transmission gear 29 is engaged with the transmission rack 27 and the rotating bevel gear rod 210 is engaged with the transmission bevel gear rod 211 and remains stable.

[0058] like Figure 7 and Figure 8 As shown, the clamping assembly described in this embodiment also includes a speed increasing gear 217, which is rotatably connected to the moving groove 28, and the speed increasing gear 217 is meshed with the speed increasing gear 1 212. A transmission rod 218 is rotatably connected in the moving block 114, and a transmission belt 1 219 is connected between the speed increasing gear 217 and the transmission rod 218. A rotating roller 220 is rotatably connected to the top of the moving block 114, and a transmission belt 221 is symmetrically connected between the transmission rod 218 and the rotating roller 220. The top of the limit block 113 and the moving block 114 are symmetrically rotatably connected with a ball 222, and a rotating roller 220 rotates between the balls 222 at the top of the limit block 113.

[0059] Specifically, the rotation of the speed increasing gear 1 212 drives the speed increasing gear 2 217 meshing therewith to rotate together, and the rotating speed increasing gear 2 217 is driven by the transmission belt 1 219 to make the transmission rod 218 rotate in the motion block 114, and then the rotating transmission rod 218 drives the rotating roller 220 to rotate through the transmission belt 2 221;

[0060] During the displacement of the moving block 114, since the ball 222 is arranged on the top of the moving block 114, the ball 222 moves with the moving block 114 when the moving block 114 is displaced, and then the ball 222 rolls on the bottom of the H-shaped steel. The rolling setting of the ball 222 reduces the contact area between the bottom between the two sides of the H-shaped steel and the ball 222, avoids the direct conflict between the bottom between the two sides of the H-shaped steel and the limit block 113 and the top of the moving block 114, and increases the contact area, resulting in an increase in the friction area between the bottom between the two sides of the H-shaped steel and the limit block 113 and the top of the moving block 114 when the moving block 114 moves, which increases the wear of the limit block 113 and the top of the moving block 114. At the same time, through the rolling of the ball 222, the limit block 113 and the moving block 114 can clamp and fix the H-shaped steel more quickly and stably.

[0061] By rotating the rotating roller 220, the H-shaped steel is displaced toward the direction close to the laser spray gun 19 under the action of the ball 222 on the limit block 113 and the moving block 114 and the rotating roller 220, thereby solving the problem that when the H-shaped steel at the clamping position of the clamping device needs to be cut, the clamping device needs to be reset and the H-shaped steel needs to be displaced due to the fixation of the H-shaped steel by the clamping device, so that the position where the H-shaped steel needs to be cut does not contact the clamping device, thereby improving the production efficiency of H-shaped steel processing and reducing the processing cost.

[0062] like Figure 7 and Figure 8 As shown, the gear ratio of the speed increasing gear 1 212 to the speed increasing gear 2 217 in this embodiment is two to one, the ball 222 and the rotating roller 220 are partially exposed at the top of the limit block 113 and the moving block 114, and the top of the ball 222 and the top of the rotating roller 220 are in the same horizontal line.

[0063] Specifically, the gear ratio of the speed-increasing gear 1 212 to the speed-increasing gear 2 217 is two to one, so that the speed-increasing gear 2 217 rotates two circles when the speed-increasing gear 1 212 rotates one circle, thereby increasing the distance that the rotating roller 220 drives the H-shaped steel thereon to move; the interference block 1 22 and the rotating roller 220 are partially exposed at the top of the limit block 113 and the moving block 114, and the top of the ball 222 is in the same horizontal line as the top of the rotating roller 220, so that the ball 222 and the rotating roller 220 are fixed on the top of the moving block 114, and their top ends are in the same horizontal line so that they can interfere with the bottom of the H-shaped steel together.

[0064] Embodiment 2

[0065] like Figures 3 to 11 As shown, compared with Example 1, another implementation of the present invention is:

[0066] like Figure 3 , Fig.10 and Fig.11 As shown, one side of the limit block 113 described in this embodiment is fixedly connected with a collection box 131, and a fixed slider 1 is slidably connected to the side where the collection box 131 and the limit block 113 are fixed, and one end of the fixed slider 132 away from the collection box 131 is fixedly connected to one side of the moving block 114, and one side of the limit block 113 is fixedly connected with a collection box 2 33, and a fixed slider 2 34 is slidably connected to the side where the collection box 2 33 and the limit block 113 are fixed, and one end of the fixed slider 2 34 away from the collection box 131 is fixedly connected to one side of the moving block 114.

[0067] Specifically, when the moving block 114 is displaced, since the collection box 1 31 and the collection box 2 33 are both fixed on the limit block 113, the moving block 114 is displaced and drives the fixed slider 1 32 and the fixed slider 2 34 fixed thereon to move together, so that the fixed slider 1 32 and the fixed slider 2 34 slide on the collection box 1 31 and the collection box 2 33 respectively, so that the collection box 1 31 and the collection box 2 33 are better fixed;

[0068] When the H-beam is cut and splashes are generated, the splashes generated during the H-beam cutting process are collected by a collection box 31 to prevent the splashes from splashing and splashes from entering some equipment, causing equipment jams or failures, resulting in inconsistent appearance of the cut products and reducing the yield rate of the products. At the same time, the splashes during the cutting process are collected to keep the working environment clean. Secondly, the collected splashes can be reused to reduce the production cost. The cut products fall into the fixed slider 32 under the action of gravity.

[0069] like Fig.10 and Fig.11 As shown, the collecting box 1 31 in this embodiment is located below the limit block 113 and the top of the moving block 114, the collecting box 2 33 is located between the collecting box 1 31 and the fixing rod 111, the collecting box 1 31 is located below the cutting position of the H-shaped steel, the bottom of the collecting box 2 33 is provided with a slope, and the width of the collecting box 2 33 is wider than that of the collecting box 1 31.

[0070] Specifically, the position setting of collecting box 1 31 and collecting box 2 33 and the width setting of collecting box 1 31 and collecting box 2 33 enable the splashes generated during the H-beam cutting process to be collected by collecting box 1 31, and the cut products fall into the wider collecting box 2 33. A slope is set at the bottom of collecting box 2 33 to make the products collected in collecting box 2 33 move inward, thereby preventing the problem that when there are too many cut products, they will accumulate at the falling place and subsequent products cannot be collected.

[0071] Working principle:

[0072] The bottom between the two sides of the H-shaped steel is placed on the top of the limit block 113 and the moving block 114 by a crane, so that the top of the limit block 113 and the moving block 114 are covered between the two sides of the H-shaped steel. At this time, the guide rod 23 is driven to rotate. Since the guide rod 23 is threadedly connected to the guide slider 24, the guide slider 24 is driven to slide and connect in the sliding groove 21 through the rotation of the guide rod 23, so that the compression spring 25 and the second resistance block 26 in the guide slider 24 move together with the guide slider 24. In the process of the resistance block 26 moving together with the guide slider 24, since the resistance block 26 is slidably connected in the guide slider 24, the resistance block 26 in the guide slider 24 contacts with the resistance block 1 22 and drives the resistance block 1 22 to move together, thereby driving the moving block 114 fixed with the resistance block 1 22 to move together with the resistance block 1 22;

[0073] When the moving block 114 is displaced together with the abutment block 1 22, the moving block 114 slides on the displacement slider 12. Since the transmission rack 27 is fixed on the displacement slider 12 and the displacement slider 12 is meshed with the transmission gear 29, as the moving block 114 is displaced, the transmission gear 29 starts to rotate under the action of the transmission rack 27, thereby driving the rotating bevel gear rod 210 fixed thereon to rotate together. Since the rotating bevel gear rod 210 is meshed with the transmission bevel gear rod 211, the rotation of the rotating bevel gear rod 210 drives the transmission bevel gear rod 211 to rotate together, so that the transmission bevel gear rod 211 rotates in the moving groove 28.

[0074] When the moving block 114 moves outward together with the abutment block 22, during this process, when the transmission bevel gear rod 211 rotates, the transmission bevel gear rod 211 will drive the rotating shaft 214 in the limiting groove 213 to rotate together with the transmission bevel gear rod 211, so that the abutment plate 215, under the action of the displacement of the rotating shaft 214 and the transmission bevel gear rod 211, is fixed by the return spring 216 and abuts against the inner wall of the limiting groove 213 in the speed-increasing gear 212. At this time, as the transmission bevel gear rod 211 continues to rotate, the abutment plate 215 abuts against the inner wall of the limiting groove 213 in the speed-increasing gear 212, with the rotating shaft 214 as the axis. The return spring 216 is elastically compressed, so that the contact plate 215 is pressed into the limit groove 213 in the transmission bevel gear rod 211, until the contact plate 215 enters the limit groove 213 in the next speed-increasing gear 1 212. At this time, the contact plate 215 does not conflict with the limit groove 213 in the speed-increasing gear 1 212. Under the action of the elastic release of the return spring 216, the contact plate 215 rotates with the rotating shaft 214 as the axis in the direction away from the return spring 216 until the contact plate 215 returns to the initial position, and so on, so that the speed-increasing gear 1 212 is stationary when the transmission bevel gear rod 211 rotates;

[0075] Because the limit block 113 is fixedly arranged, when the moving block 114 is displaced, it is displaced at the bottom of the H-shaped steel under the limiting action of the limit block 113. During the displacement of the moving block 114, because the moving block 114 and the top of the limit block 113 are provided with a ball 222, when the moving block 114 is displaced, the ball 222 moves together with the moving block 114, and then the ball 222 rolls at the bottom of the H-shaped steel, thereby clamping and fixing the H-shaped steel;

[0076] When the moving block 114 contacts the inner wall of one side of the H-shaped steel, the H-shaped steel is clamped and fixed under the action of the limit block 113 and the moving block 114. At this time, the contact block 1 22 is stationary. When the guide slider 24 continues to move, the contact block 26 contacts the contact block 1 22 under the action of the displacement of the guide slider 24, so that the contact block 26 slides downward in the guide slider 24 and elastically compresses the compression spring 25 until the contact block 26 passes through the contact block 1 22. The compression spring 25 begins to release elastically, so that the contact block 26 slides upward in the compression spring 25 until it returns to the initial position.

[0077] When the moving block 114 is displaced, since the collecting box 1 31 and the collecting box 2 33 are both fixed on the limiting block 113, the moving block 114 is displaced and drives the fixed slider 1 32 and the fixed slider 2 34 fixed thereon to move together, so that the fixed slider 1 32 and the fixed slider 2 34 slide on the collecting box 1 31 and the collecting box 2 33 respectively, so that the collecting box 1 31 and the collecting box 2 33 are better fixed;

[0078] In actual use, a motor can be installed inside the support base 11 to drive the transmission gear 14 to rotate, and the rotation of the transmission gear 14 drives the guide rack 13 to move, and then the displacement of the guide rack 13 drives the displacement slider 12 thereon to slide on the support base 11, and the displacement of the displacement slider 12 drives the clamping device to move, so that the H-shaped steel on the clamping device moves together with the clamping device;

[0079] When the H-shaped steel on the clamping device is displaced to below the top of the fixed block 1, the external motor on the transmission gear 14 is turned off to stop the clamping device from being displaced, thereby stopping the H-shaped steel on the clamping device from moving, and starting the external motor on the displacement rod 15 to drive the displacement rod 15 to rotate through the output end of the external motor on the displacement rod 15. Since the displacement rod 15 is threadedly connected to the displacement block 17, the displacement block 17 is displaced by the rotation of the displacement rod 15, and then the displacement block 17 is displaced on the support rod 16 through the displacement of the displacement block 17, so that the electric telescopic rod 18 fixed on the displacement block 17 is displaced together with the displacement block 17. When the displacement block 17 is displaced to the required cutting position, the electric telescopic rod 18 is started to extend the electric telescopic rod 18, and the extension of the electric telescopic rod 18 drives the laser spray gun 19 on the electric telescopic rod 18 to move downward together with the extension of the electric telescopic rod 18, so that the nozzle of the laser spray gun 19 is close to the H-shaped steel. The outer surface, at this time, the laser spray gun 19 and the high-pressure air gun 110 are started, and the laser beam ejected by the laser spray gun 19 cuts the H-shaped steel below the nozzle of the laser spray gun 19, and the high-pressure gas ejected by the electric telescopic rod 18 blows away the splashes generated by the laser beam cutting the H-shaped steel. When cutting both sides of the H-shaped steel, the external motor on the laser spray gun 19 is started at this time, and the laser spray gun 19 is driven to rotate through the output end of the external motor on the laser spray gun 19, so that the nozzle of the laser spray gun 19 is kept vertical to one side of the H-shaped steel. At this time, the laser spray gun 19 and the electric telescopic rod 18 are started, and one side of the H-shaped steel is cut by extending the electric telescopic rod 18, and this operation is repeated on the other side of the H-shaped steel. In this process, the processing and cutting of the H-shaped steel are completed by the displacement of the displacement block 17, the extension of the electric telescopic rod 18, the steering of the laser spray gun 19 and the movement of the clamping device, thereby producing the desired product.

[0080] When the H-beam is cut, the spatter is collected by a collecting box 31, and the cut product falls into a fixed slider 32 under the action of gravity.

[0081] When the H-shaped steel at the clamping position of the limit block 113 and the moving block 114 needs to be cut, the moving block 114 moves inward together with the resistance block 1 22, and the transmission gear 2 29 rotates in the opposite direction, so that the rotating bevel gear rod 210 rotates in the opposite direction together with the transmission gear 29, thereby driving the transmission bevel gear rod 211 to rotate in the opposite direction. During the reverse rotation of the transmission bevel gear rod 211, the support base 11 drives the rotating shaft 214 in the limit groove 213 to rotate together with the transmission bevel gear rod 211, thereby causing the resistance plate 215 to move with the displacement of the rotating shaft 214 and the transmission bevel gear rod 211 through the reset spring 216. The contact plate 215 is fixed and contacts the inner wall of the inner limit groove 213 of the speed increasing gear 212. At this time, as the transmission bevel gear rod 211 continues to rotate, the contact plate 215 rotates in the direction away from the return spring 216 with the rotating shaft 214 as the axis under the contact of the inner wall of the inner limit groove 213 of the speed increasing gear 212, and elastically stretches the return spring 216, so that the contact plate 215 is stationary under the contact between the inner wall of the inner limit groove 213 of the speed increasing gear 212 and the inner wall of the inner limit groove 213 of the transmission bevel gear rod 211, and then drives the speed increasing gear 212 to rotate together with the transmission bevel gear rod 211 through the rotation in the direction of the transmission bevel gear rod 211.

[0082] The rotation of the speed increasing gear 1 212 drives the speed increasing gear 2 217 meshing with it to rotate together. The rotating speed increasing gear 2 217 drives the transmission rod 218 in the moving block 114 through the transmission of the transmission belt 1 219. Then the rotating transmission rod 218 drives the rotating roller 220 to rotate through the transmission of the transmission belt 2 221. Through the rotation of the rotating roller 220, the H-shaped steel is displaced under the action of the ball 222 and the rotating roller 220 on the limit block 113 and the moving block 114.

It should be understood by those skilled in the art that the present invention is not limited to the above embodiments.
