A cutting device for processing special-shaped steel

Abstract

The present invention belongs to the field of cutting technology, and specifically is a cutting device for processing special-shaped steel, comprising a frame; a feed guide module and a discharge guide module arranged at both ends of the frame; a slide rail arranged at the top of the frame, and a fixed seat sliding on the slide rail. A clamping unit is used to replace a traditional fixed clamping device. In the process of the H-shaped steel moving from the feed guide module to the discharge guide module, the displacement end of the H-shaped steel will preferentially touch a contact cylinder, and squeeze the contact cylinder under the pushing action of the feed guide module, so that the contact cylinder generates an outward thrust. When there is an outward thrust on the contact cylinder, the double-headed connecting arm in the middle thereof can be driven to deflect, so that the clamping arm originally far away from the displacement trajectory of the H-shaped steel is transferred to be close to the H-shaped steel, so that the clamping arm can be closely attached to both sides of the H-shaped steel, thereby achieving a correction effect on the horizontal deviation of the H-shaped steel from the displacement trajectory. After the horizontal correction, the displacement end of the H-shaped steel moves to the discharge guide module.

Description

Technical Field

[0001] The invention belongs to the field of cutting technology, in particular to a cutting device for processing special-shaped steel. Background Art

[0002] Special-shaped steel is a special form of steel, which is characterized by irregular or special cross-sectional shapes, which is different from standard simple cross-sectional steel such as square steel, round steel, etc. In the classification of steel, it belongs to one of the four major varieties, namely the "shaped" part of the section, wire, plate, and tube. Due to the particularity and complexity of its shape, special-shaped steel has a wide range of applications in many specific fields, such as construction, automobiles, shipbuilding, etc.

[0003] As a kind of special-shaped steel, H-shaped steel is different from traditional square steel and round steel in cutting and processing. It is impossible to ensure the stability during the processing and it is difficult to avoid the possibility of cutting deviation by using simple clamping equipment. Therefore, H-shaped steel needs to be clamped and fixed by a clamping equipment with a specific structure during the cutting process. In the current existing technology, axially and longitudinally arranged clamping rollers are used to clamp and fix the H-shaped steel from multiple directions to ensure that the H-shaped steel will not produce a large displacement during the cutting process of the laser cutting machine, thereby avoiding deviations during the cutting process.

[0004] In the current prior art, when the H-beam is clamped and fixed using axially and longitudinally arranged clamping rods, since such clamping equipment is generally arranged on a cutting table, when the feed guide module pushes the H-beam to move so as to pass the H-beam through the clamping equipment, as the displacement end of the H-beam is pushed gradually moves away from the feed port, it is impossible to accurately pass the displacement end of the H-beam through the fixedly arranged clamping equipment, and manual intervention is required to align the displacement end of the H-beam with the clamping equipment; however, in the actual H-beam cutting process, due to the large number of H-beam batch cutting processes, after one H-beam is cut, the next H-beam is clamped and fixed, and manual intervention is required each time to align the displacement end of the H-beam with the clamping equipment, and the process is relatively cumbersome.

DETAILED DESCRIPTION

[0042] 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.

[0043] like Figures 1 to 6 As shown, a cutting device for processing special-shaped steel described in an embodiment of the present invention includes a frame 1; a feed guide module and a discharge guide module arranged at both ends of the frame 1; a slide rail 100 arranged on the top of the frame 1, and a fixed seat 5 sliding on the slide rail 100, for fixing the laser cutting machine; also includes a clamping unit 3 for clamping H-shaped steel 6; the clamping unit 3 includes a base 310; a double-headed connecting arm 330 is rotatably connected to the base 310; a contact cylinder 350 and a clamping arm 360 are respectively rotatably connected to the double-headed connecting arm 330; the clamping arm 360 is used to clamp the H-shaped steel 6.

[0044] In the prior art, when the displacement end of the H-beam 6 passes through the clamping device, since the displacement end of the H-beam 6 gradually moves away from the feed port during the pushing process, it may deviate from the horizontal line, resulting in the H-beam 6 being unable to accurately pass through the fixedly arranged clamping device. At this time, human intervention is required to achieve the accurate passage of the displacement end of the H-beam 6 through the clamping device. The process is relatively cumbersome and requires precise coordination of manpower, clamping equipment, and feed guide module. In view of this, in one embodiment, a clamping unit 3 is used to replace the traditional fixedly arranged clamping device. In the process of the H-beam 6 moving from the feed guide module to the discharge guide module, In the process, the displacement end of the H-beam 6 will first touch the contact cylinder 350, and squeeze the contact cylinder 350 under the pushing action of the feed guide module, so that the contact cylinder 350 generates an outward thrust. When there is an outward thrust on the contact cylinder 350, it can drive the double-headed connecting arm 330 in the middle to deflect, so that the clamping arm 360 that was originally far away from the displacement track of the H-beam 6 is transferred to the H-beam 6, so that the clamping arm 360 can be closely attached to both sides of the H-beam 6, thereby achieving the effect of correcting the horizontal deviation of the H-beam 6 from the displacement track. After the horizontal correction, the displacement end of the H-beam 6 moves to the discharge guide module;

[0045] During the cutting process, since the H-beam 6 has been corrected, after the cutting position is determined, the laser cutting machine on the fixed seat 5 moves radially to cut the H-beam 6. After the cutting is completed, the H-beam 6 is pushed out by the feed guide module through the discharge guide module, and then the next H-beam 6 is cut. Among them, a torsion spring is arranged between the double-head connecting arm 330 and the base 310. When the H-beam 6 between the two contact cylinders 350 is moved away, the two contact cylinders 350 are reset to a close contact state.

[0046] like Figures 1 to 6 As shown, it also includes a first support unit 2; the first support unit 2 includes:

[0047] The first bracket 200 is fixed in the frame 1;

[0048] The first fixing frame 210 is configured as a U-shaped structure and is rotatably connected to the inner side of the first bracket 200;

[0049] A first guide roller 220, rotatably connected to the bottom of the first fixing frame 210;

[0050] The first pressing roller 230 is rotatably connected to the top of the first bracket 200 via the first connecting shaft 2301;

[0051] The H-shaped steel 6 passes through the first fixing frame 210 , and the first guide roller 220 and the first pressing roller 230 are respectively located at the upper and lower sides of the H-shaped steel 6 .

[0052] As mentioned above, after the clamping unit 3 is used to correct the H-beam 6 in the horizontal direction, since the feed guide module and the discharge guide module may be far apart, the H-beam 6 may still deviate from the displacement trajectory in the vertical direction. Therefore, only the clamping unit 3 cannot solve the deviation problem in the vertical direction. In one embodiment, the first support unit 2 is used in conjunction with the clamping unit 3 to correct the H-beam 6 in multiple directions, including the vertical direction and the horizontal direction, so as to ensure that the H-beam 6 can move from the feed guide module to the discharge guide module according to the predetermined displacement trajectory during the cutting process. At this time, the laser cutting machine is used to cut the H-beam 6 to avoid the problem of cutting deviation.

[0053] Specifically, in the process of the displacement end of the H-beam 6 moving from the feed guide module to the discharge guide module, the displacement end of the H-beam 6 passes through the first fixed frame 210. When the displacement end of the H-beam 6 passes through the first fixed frame 210, since the initial state of the first fixed frame 210 is nearly parallel to the plumb plane, and the first fixed frame 210 is set to be U-shaped, the H-beam 6 can easily pass through the first fixed frame 210 even if a small range of deviation occurs when passing through the first fixed frame 210. After the displacement end of the H-beam 6 contacts the contact cylinder 350, the two clamps deflect in the direction of the H-beam 6 to achieve horizontal deviation correction of the displacement end of the H-beam 6. Then, the first fixed frame 210 is controlled to deflect, and the first guide roller 220 cooperates with the first pressure roller 230 to reset the H-beam 6 to the horizontal direction, thereby achieving deviation correction of the H-beam 6 in the vertical direction.

[0054] By correcting the H-beam 6 in multiple directions, it can be ensured that the displacement end of the H-beam 6 does not deviate from the predetermined displacement trajectory without human intervention, and at the same time, its displacement end can smoothly pass through the discharge guide module.

[0055] like Figures 1 to 6 As shown, a first spring 240 is also fixed to the outer side of the bottom of the first fixed frame 210, and the two ends of the first spring 240 are respectively fixed to the bottom of the first fixed frame 210 and the central axis of the first guide roller 220; a waist-shaped groove is opened at the bottom of the first bracket 200, and the central axis of the first guide roller 220 passes through the waist-shaped groove.

[0056] A rotating shaft is fixedly connected to the base 310, and the double-headed connecting arm 330 is rotatably connected to the rotating shaft; a first rotating wheel 320 is rotatably connected to the rotating shaft of one of the bases 310; a first rope 370 is fixedly connected between the bottom of one end of the double-headed connecting arm 330 corresponding to the clamping arm 360 and the first connecting shaft 2301, and the first rope 370 is wound around the first rotating wheel 320.

[0057] In one embodiment, when the displacement end of the H-beam 6 moves from the feed guide module to the discharge guide module under the pushing action of the feed guide module, the displacement end of the H-beam 6 contacts the contact cylinder 350 after passing through the first fixing frame 210. Under the pushing action of the feed guide module, the displacement end of the H-beam 6 squeezes the contact cylinder 350 to deflect outward, and at the same time drives the clamping arm 360 that was originally away from the moving track of the H-beam 6 to approach the H-beam 6, and finally clamps on both sides of the H-beam 6.

[0058] When the contact cylinder 350 is squeezed and deflected outward, the double-headed connecting arm 330 deflects along with the contact cylinder 350, so the clamping arm 360 also deflects accordingly, which in turn drives the end of the double-headed connecting arm 330 corresponding to the clamping arm 360 to deflect, so that the first rope 370 is tightened, thereby driving the first guide roller 220 at the other end of the first rope 370 to move toward the H-beam 6, so that the first guide roller 220 and the first pressure roller 230 contact the H-beam 6. When the first pressure roller 230 moves toward the H-beam 6, the first guide roller 220 at the bottom of the first fixing frame 210 also moves toward the H-beam 6, thereby applying an upward pressure to the H-beam 6, so that the H-beam 6 also obtains a deviation correction effect in the vertical direction.

[0059] Based on this, the H-beam 6 contacts the clamping unit 3 under the pushing action of the feed guide module to achieve the horizontal correction of the H-beam 6, and then the deflection of the double-head connecting arm 330 drives the first support unit 2 to correct the H-beam 6 in the vertical direction. No human intervention is required to achieve the horizontal and vertical correction of the H-beam 6, so that the H-beam 6 can be smoothly moved from the feed guide module to the discharge guide module under the pushing action of the feed guide module, and the first support unit 2 and the clamping unit 3 always maintain the correction effect on the H-beam 6 before the cutting is completed, so as to ensure that the H-beam 6 does not deviate during the cutting process and ensure the stability of the H-beam 6 during the cutting process.

[0060] like Figures 4 to 5 As shown, it also includes a second support unit 4; the first support unit 2 and the second support unit 4 are respectively arranged on both sides of the clamping unit 3, and the second support unit 4 is arranged adjacent to the discharge guide module.

[0061] The second support unit 4 includes a second bracket 400, a second fixed frame 410, a second guide roller 420, a second pressure roller 430, a second connecting shaft 4301 and a second spring 440; the second bracket 400 is fixedly connected to the inner bottom surface of the frame 1; the second fixed frame 410 is rotatably connected to the inner side of the second bracket 400, and the second guide roller 420 is rotatably connected to the bottom of the second fixed frame 410; the second pressure roller 430 is rotatably connected to the top of the second fixed frame 410 via the second connecting shaft 4301; the second spring 440 is arranged on the outer side of the bottom of the second fixed frame 410, and the two ends are respectively fixed to the central axes of the second fixed frame 410 and the second guide roller 420.

[0062] Since the H-beam 6 is cut by the laser cutting machine, the original section of the H-beam 6 is now divided into two sections. When the section of the H-beam 6 that contacts the discharge guide module is separated from the contact cylinder 350 by the pushing action of the feed guide module, the two contact cylinders 350 deflect inward until they are in contact with each other. At this time, the end of the section of the H-beam 6 that contacts the discharge guide module, which is located in the frame 1, may sink, that is, deviate from the horizontal direction. At this time, the discharge guide module cannot drive the section of the H-beam 6 to move out of the frame 1, thereby causing a jamming phenomenon.

[0063] In response to the above, in one embodiment, a second support unit 4 is provided adjacent to one side of the clamping unit 3, similar to the first support unit 2, so that the H-beam 6 can pass through the second fixed frame 410 when moving from the feed guide module to the discharge guide module, and when one end of a section of the H-beam 6 located in the frame 1 sinks, the second fixed frame 410 in the second support unit 4 can be deflected to drive the second guide roller 420 and the second pressure roller 430 to restore the section of the H-beam 6 to a horizontal state, thereby preventing the end of the section of the H-beam 6 located in the frame 1 from sinking and causing a jam.

[0064] like Figure 6 to Figure 7 As shown, a connecting shaft is fixedly connected to the side of the other base 310, and a second rotating wheel 340 is rotatably connected to the connecting shaft; a second rope 380 is fixedly connected between the first connecting shaft 2301 and the second connecting shaft 4301, and the second rope 380 is wound around the second rotating wheel 340.

[0065] In continuation of the above, after the laser cutting machine cuts the H-beam 6 into two, a section of the H-beam 6 close to the discharge guide module is separated from the contact cylinder 350 under the action of the discharge guide module, and at this time, the double-headed clamp arm 360 is reset under the action of the torsion spring, and the clamp arm 360 no longer clamps the H-beam 6, and the first support unit 2 is also reset to the initial state; in order to enable the second support unit 4 to limit and correct the section of the H-beam 6 close to the discharge guide module at this time, that is, when the first support unit 2 is reset, the second support unit 4 can play a correcting effect on the H-beam 6;

[0066] In one embodiment, the second rope 380 is used to connect the first support unit 2 and the second support unit 4. In the initial state, when no external force is applied, the first support unit 2 has a larger counterweight, and the second rope 380 can be pulled to deflect the first support unit 2 to the second pressure roller 430 and the second guide roller 420 to be nearly parallel. When the H-shaped steel 6 passes through the clamping unit 3, the first rope 370 pulls the first support unit 2, so that the first pressure roller 230 and the first guide roller 220 can be attached to the upper and lower sides of the H-shaped steel 6, and the second support unit 4 is not pulled by the second rope 380 at this time, that is, it can be reset to the initial state, that is, the second pressure roller 430 and the second guide roller 420 are approximately parallel to the vertical plane.

[0067] The first fixing frame 210 has a counterweight at its bottom, which is approximately parallel to the vertical plane in the initial state, and the second fixing frame 410 also has a counterweight at its bottom, but its overall weight is less than that of the first fixing frame 210, which is approximately parallel to the vertical plane in the initial state;

[0068] When a section of H-beam 6 is separated from the contact cylinder 350, the first fixing frame 210 in the first supporting unit 2 is reset, and the second fixing frame 410 in the second supporting unit 4 is deflected by pulling the second rope 380, so that the second pressing roller 430 and the second guiding roller 420 can correct the deviation of the section of H-beam 6, thereby preventing one end of the section of H-beam 6 located in the frame 1 from sinking and causing a jam.

[0069] like Figures 6 to 9 As shown, the contact cylinder 350 includes a shell 3501 and a planetary gear 3502; teeth 3503 are arranged on the inner side of the top of the shell 3501; a deflection arm 3505 is coaxially rotatably connected to the top of one end of the double-headed connecting arm 330; the deflection arm 3505 is rotatably connected to the center gear 3504 at one end away from the double-headed connecting arm 330, and the center gear 3504 is coaxial with the shell 3501; a plurality of planetary gears 3502 are arranged, and a plurality of planetary gears 3502 are arranged in a circular array; one of the planetary gears 3502 is rotatably connected to the top of one end of the double-headed connecting arm 330; the center gear 3504 is meshed with a plurality of planetary gears 3502, and the planetary gears 3502 are also meshed with teeth 3503.

[0070] In order to enable the two contact cylinders 350 to drive the clamping arm 360 to deflect to a larger angle after being squeezed, the contact cylinder 350 and the double-headed connecting arm 330 are set to be eccentrically arranged. However, in order to ensure that the contact cylinder 350 can stably rotate around one end of the double-headed connecting arm 330 when being squeezed, a planetary gear 3502 is set on the top of the double-headed connecting arm 330 to cooperate with the teeth 3503 inside the contact cylinder 350. When squeezed, the contact cylinder 350 can stably rotate through the cooperation of the planetary gear 3502, the central gear 3504 and the teeth 3503, wherein the central gear 3504 is rotatably connected to the double-headed connecting arm 330 via the deflection arm 3505, so that the contact cylinder 350 can stably rotate around one end of the double-headed connecting arm 330.

[0071] like Figures 1 to 3 As shown, the feed guiding module includes a front end plate 110; two first deflection correcting rollers 1101 are rotatably connected to the front end plate 110; a plurality of first guide rollers 1102 are also rotatably connected to the front end plate 110; the first deflection correcting rollers 1101 are perpendicular to the front end plate 110, and the first guide rollers 1102 are parallel to the front end plate 110.

[0072] The above-mentioned feed guiding module pushes the H-beam 6. In one embodiment, the first deflection correcting roller 1101 on the front end plate 110 is driven by a motor, and the rotating shafts of the two first deflection correcting rollers 1101 are connected by gears. When the motor is started, the two first deflection correcting rollers 1101 push the H-beam 6 into the frame 1; wherein, after the cutting is completed, in order to speed up the cutting cycle, the feed guiding module is also used to rewind another section of the H-beam 6 after cutting, and control the motor to reverse. Since the clamping unit 3 no longer clamps the H-beam 6 at this time, the other section of the H-beam 6 can be driven by the two first deflection correcting rollers 1101 to move out of the frame 1 through the feed guiding module.

[0073] like Figures 1 to 3 As shown, the discharge guiding module includes a rear end plate 120; two second deviation correcting rollers 1201 are correspondingly rotatably connected to the rear end plate 120, and a plurality of second guide rollers 1202 are correspondingly rotatably connected to the rear end plate 120; the second deviation correcting rollers 1201 are perpendicular to the rear end plate 120, and the second guide rollers 1202 are parallel to the rear end plate 120.

[0074] In one embodiment, similar to the feed guide module, the two second correcting rollers 1201 are driven by independent motors, and the rotating shafts of the two second correcting rollers 1201 are also connected by gears. When the motor is started, the two second correcting rollers 1201 push the H-shaped steel 6 out of the frame 1.

[0075] Working principle: In the prior art, when the displacement end of the H-beam 6 passes through the clamping device, the displacement end of the H-beam 6 gradually moves away from the feed port during the pushing process, which may deviate from the horizontal line, resulting in the H-beam 6 being unable to accurately pass through the fixedly arranged clamping device. At this time, human intervention is required to achieve accurate passage of the displacement end of the H-beam 6 through the clamping device. The process is relatively cumbersome and requires precise coordination of manpower, clamping equipment, and feed guide module. In view of this, in one embodiment, a clamping unit 3 is used to replace the traditional fixedly arranged clamping device, and when the H-beam 6 moves from the feed guide module to the discharge guide module During the process, the displacement end of the H-beam 6 will first touch the contact cylinder 350, and squeeze the contact cylinder 350 under the pushing action of the feed guide module, so that the contact cylinder 350 generates an outward thrust. When there is an outward thrust on the contact cylinder 350, it can drive the double-headed connecting arm 330 in the middle to deflect, so that the clamping arm 360 that was originally far away from the displacement trajectory of the H-beam 6 is transferred to the H-beam 6, so that the clamping arm 360 can be closely attached to both sides of the H-beam 6, thereby achieving the effect of correcting the horizontal deviation of the H-beam 6 from the displacement trajectory. After the horizontal correction, the displacement end of the H-beam 6 moves to the discharge guide module;

[0076] During the cutting process, since the H-beam 6 has been corrected, after the cutting position is determined, the laser cutting machine on the fixed seat 5 moves radially to cut the H-beam 6. After the cutting is completed, the H-beam 6 is pushed out by the feed guide module through the discharge guide module, and then the next H-beam 6 is cut. Among them, a torsion spring is arranged between the double-head connecting arm 330 and the base 310. When the H-beam 6 between the two contact cylinders 350 is moved away, the two contact cylinders 350 are reset to a close contact state.

[0077] After the clamping unit 3 is used to correct the H-beam 6 in the horizontal direction, since the feed guide module and the discharge guide module may be far apart, the H-beam 6 may still deviate from the displacement trajectory in the vertical direction. Therefore, only the clamping unit 3 cannot solve the deviation problem in the vertical direction. In one embodiment, the first support unit 2 is used in conjunction with the clamping unit 3 to correct the H-beam 6 in multiple directions, including the vertical direction and the horizontal direction, so as to ensure that the H-beam 6 can move from the feed guide module to the discharge guide module according to the predetermined displacement trajectory during the cutting process. At this time, the laser cutting machine is used to cut the H-beam 6 to avoid the problem of cutting deviation.

[0078] Specifically, in the process of the displacement end of the H-beam 6 moving from the feed guide module to the discharge guide module, the displacement end of the H-beam 6 passes through the first fixed frame 210. When the displacement end of the H-beam 6 passes through the first fixed frame 210, since the initial state of the first fixed frame 210 is nearly parallel to the plumb plane, and the first fixed frame 210 is set to be U-shaped, the H-beam 6 can easily pass through the first fixed frame 210 even if a small range of deviation occurs when passing through the first fixed frame 210. After the displacement end of the H-beam 6 contacts the contact cylinder 350, the two clamps deflect in the direction of the H-beam 6 to achieve horizontal deviation correction of the displacement end of the H-beam 6. Then, the first fixed frame 210 is controlled to deflect, and the first guide roller 220 cooperates with the first pressure roller 230 to reset the H-beam 6 to the horizontal direction, thereby achieving deviation correction of the H-beam 6 in the vertical direction.

[0079] By correcting the H-beam 6 in multiple directions, it can be ensured that the displacement end of the H-beam 6 does not deviate from the predetermined displacement trajectory without human intervention, and at the same time, its displacement end can smoothly pass through the discharge guide module.

[0080] In one embodiment, when the displacement end of the H-beam 6 moves from the feed guide module to the discharge guide module under the pushing action of the feed guide module, the displacement end of the H-beam 6 contacts the contact cylinder 350 after passing through the first fixing frame 210. Under the pushing action of the feed guide module, the displacement end of the H-beam 6 squeezes the contact cylinder 350 to deflect outward, and at the same time drives the clamping arm 360 that was originally away from the moving track of the H-beam 6 to approach the H-beam 6, and finally clamps on both sides of the H-beam 6.

[0081] When the contact cylinder 350 is squeezed and deflected outward, the double-headed connecting arm 330 deflects along with the contact cylinder 350, so the clamping arm 360 also deflects accordingly, which in turn drives the end of the double-headed connecting arm 330 corresponding to the clamping arm 360 to deflect, so that the first rope 370 is tightened, thereby driving the first guide roller 220 at the other end of the first rope 370 to move toward the H-beam 6, so that the first guide roller 220 and the first pressure roller 230 contact the H-beam 6. When the first pressure roller 230 moves toward the H-beam 6, the first guide roller 220 at the bottom of the first fixing frame 210 also moves toward the H-beam 6, thereby applying an upward pressure to the H-beam 6, so that the H-beam 6 also obtains a deviation correction effect in the vertical direction.

[0082] Based on this, the H-beam 6 contacts the clamping unit 3 under the pushing action of the feed guide module to achieve the horizontal correction of the H-beam 6, and then the deflection of the double-head connecting arm 330 drives the first support unit 2 to correct the H-beam 6 in the vertical direction. No human intervention is required to achieve the horizontal and vertical correction of the H-beam 6, so that the H-beam 6 can be smoothly moved from the feed guide module to the discharge guide module under the pushing action of the feed guide module, and the first support unit 2 and the clamping unit 3 always maintain the correction effect on the H-beam 6 before the cutting is completed, so as to ensure that the H-beam 6 does not deviate during the cutting process and ensure the stability of the H-beam 6 during the cutting process.

[0083] In continuation of the above, after the laser cutting machine cuts the H-beam 6 into two, a section of the H-beam 6 close to the discharge guide module is separated from the contact cylinder 350 under the action of the discharge guide module, and at this time, the double-headed clamp arm 360 is reset under the action of the torsion spring, and the clamp arm 360 no longer clamps the H-beam 6, and the first support unit 2 is also reset to the initial state; in order to enable the second support unit 4 to limit and correct the section of the H-beam 6 close to the discharge guide module at this time, that is, when the first support unit 2 is reset, the second support unit 4 can play a correcting effect on the H-beam 6;

[0084] In one embodiment, the second rope 380 is used to connect the first support unit 2 and the second support unit 4. In the initial state, when no external force is applied, the first support unit 2 has a larger counterweight, and the second rope 380 can be pulled to deflect the first support unit 2 to the second pressure roller 430 and the second guide roller 420 to be nearly parallel. When the H-shaped steel 6 passes through the clamping unit 3, the first rope 370 pulls the first support unit 2, so that the first pressure roller 230 and the first guide roller 220 can be attached to the upper and lower sides of the H-shaped steel 6, and the second support unit 4 is not pulled by the second rope 380 at this time, that is, it can be reset to the initial state, that is, the second pressure roller 430 and the second guide roller 420 are approximately parallel to the vertical plane.

[0085] The first fixing frame 210 has a counterweight at its bottom, which is approximately parallel to the vertical plane in the initial state, and the second fixing frame 410 also has a counterweight at its bottom, but its overall weight is less than that of the first fixing frame 210, which is approximately parallel to the vertical plane in the initial state;

[0086] When a section of H-beam 6 is separated from the contact cylinder 350, the first fixing frame 210 in the first supporting unit 2 is reset, and the second fixing frame 410 in the second supporting unit 4 is deflected by pulling the second rope 380, so that the second pressing roller 430 and the second guiding roller 420 can correct the deviation of the section of H-beam 6, thereby preventing one end of the section of H-beam 6 located in the frame 1 from sinking and causing a jam.
