Description

Technical Field

[0001] This invention belongs to the technical field of steel beam cutting equipment, specifically relating to a continuous cutting device for steel beam processing. Background Technology

[0002] Steel beams are horizontal or diagonal load-bearing components made of steel, mainly used in engineering structures such as buildings, bridges, and industrial facilities to bear loads and transfer them to the support system. Based on their cross-sectional shape, they can be divided into I-beams, H-beams, box beams, etc. Among them, I-beams are the most commonly used due to their good shear resistance in the web and high bending efficiency in the flanges. Steel beams are combined with other components through welding, bolting, or riveting to form steel frame structures. However, when cutting H-beams, a 30°~45° V-shaped bevel needs to be cut to facilitate welding at the ends, thus allowing for tighter welding of the steel beam with other components and improving joint strength.

[0003] Currently, when cutting steel beams, a small section is typically cut using a right-angle cutting device, followed by a V-shaped bevel cut using an angled cutting device. This process cannot complete the cutting of the steel beam in one go, requiring two different cutting devices, which significantly reduces cutting efficiency. Furthermore, the cutting disc is usually fixed during the cutting process and cannot be adjusted according to the specific angle of the V-shaped bevel, resulting in the ability to cut only one type of V-shaped bevel. If different angles of V-shaped bevels are required, the cutting equipment needs to be changed, increasing cutting costs. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a continuous cutting device for steel beam processing.

[0005] The technical solution adopted to solve the above technical problems is: a continuous cutting equipment for steel beam processing, including a first support frame, a base frame and a second support frame, a moving mechanism is fixedly installed at the top center of the first support frame, the moving mechanism is provided with a tightening mechanism, and a limiting mechanism is fixedly connected to the top of the first support frame near the base frame. A rotating mechanism is fixedly connected to the top of the base frame. The rotating mechanism is equipped with multiple adjusting mechanisms, and the top of each of the multiple adjusting mechanisms is respectively equipped with a cutting mechanism, two receiving mechanisms, and a top material mechanism. A conveying assembly is fixedly installed on the top of the second support frame, and a first receiving box and a second receiving box are provided inside the base frame.

[0006] Furthermore, the moving mechanism includes a movable frame fixedly connected to the top of the first support frame, a plurality of rollers are mounted on the top of the movable frame, two slide rails are fixedly connected to the top of the movable frame, and a rack is fixedly connected to the top of the movable frame and between the two slide rails.

[0007] With the above technical solution, when cutting the steel beam, the steel beam is placed on multiple rollers and tightened by a tightening mechanism. The other end of the steel beam is pressed against by a limiting mechanism. The tightening mechanism pushes the steel beam to cut it into small segments in an orderly manner. The operation is automated and the cutting efficiency is improved.

[0008] Furthermore, the tightening mechanism includes two slide blocks slidably connected to two slide rails. A movable plate is fixedly connected to the top of the two slide blocks. A first motor is fixedly installed on one side of the top of the movable plate. A first gear is fixedly connected to the outer wall of the output shaft of the first motor. A first fixed frame is fixedly connected to the top of one side of the movable plate. A first threaded groove is provided at the center of the top of the first fixed frame. A threaded rod is threadedly connected to the first threaded groove. A limit rod is fixedly connected to the bottom end of the threaded rod. A limit cylinder is rotatably connected to the bottom of the first fixed frame at the bottom end of the first threaded groove. A first bevel gear is fixedly connected to the outer wall of the limit cylinder. Rotary rods are rotatably connected to the front and rear ends of the first fixed frame. A second threaded groove is provided on the outer wall of each of the two rotary rods. A second bevel gear is fixedly connected to the inner end of the outer wall of each of the two rotary rods. Threaded cylinders are threadedly connected to each of the two rotary rods through the second threaded grooves. Tightening plates are fixedly connected to the outer ends of each of the two threaded cylinders. Limit strips are fixedly connected to the bottom ends of the outer walls of each of the two threaded cylinders. Limit grooves are provided at the front and rear ends of the top of the first fixed frame.

[0009] With the above technical solution, when the steel beam is tightened, one end face of the moving plate is attached to one end of the steel beam. Rotating the threaded rod drives the limiting rod to rotate, which in turn drives the limiting cylinder and the first bevel gear to rotate, which in turn drives the two second bevel gears to rotate. All of these drive the threaded cylinder connected to the beam to rotate. Under the action of the corresponding limiting strip and limiting groove, the threaded cylinder moves outward, thereby causing the two tightening plates to adhere to the inner walls of the front and rear ends of the steel beam. When the threaded rod is tightened, the steel beam is tightened through the two tightening plates, thereby fixing the steel beam during cutting and improving cutting accuracy.

[0010] Furthermore, the first gear meshes with the rack, the limiting rod passes through the limiting cylinder, the first bevel gear meshes with two second bevel gears, and the two limiting bars are slidably connected to their respective limiting grooves.

[0011] With the above technical solution, when the steel beam needs to be cut, the first motor is started, and the first gear is driven to mesh and rotate on the rack through the output shaft, thereby driving the entire moving plate to move the steel beam, which facilitates the subsequent cutting mechanism to cut it. The automation effect is strong and the cutting efficiency of the steel beam is improved.

[0012] Furthermore, the limiting mechanism includes a frame fixedly connected to one side of the top of the first support frame. A first cylinder is fixedly installed on the top of one side and the front and rear ends of one side of the frame. One end of each of the first cylinder pistons is fixedly connected to a wheel frame, and pulleys are installed on each of the wheel frames.

[0013] With the above technical solution, when cutting the steel beam, multiple first cylinders are activated. Each of the first cylinders pushes a connected pulley through a piston, so that all the pulleys contact the steel beam. Two of the pulleys press against the front and rear ends of the steel beam, while the other pulley presses against the top of the steel beam. This gives the steel beam a certain degree of stability during movement, thereby greatly improving the cutting accuracy.

[0014] Furthermore, the rotating mechanism includes two second fixed frames fixedly connected to the top of the base frame. A rotating shaft is rotatably connected to the center of one of the second fixed frames. A movable ring frame is fixedly connected to the rear end of the outer wall of the rotating shaft. The front end of the movable ring frame is provided with a scale. A third gear is fixedly connected to the front end of the outer wall of the rotating shaft. A second motor is fixedly installed at the front end of one of the second fixed frames. A fourth gear is fixedly connected to the outer wall of the output shaft of the second motor. The fourth gear meshes with the third gear. A limiting ring frame is fixedly connected to the center of the other second fixed frame. An annular groove is opened at the front end of the limiting ring frame.

[0015] The above technical solution allows for the following process: When a steel beam needs to be cut into a V-shaped bevel, the second motor is started, which drives the fourth gear to rotate via the output shaft. This, in turn, drives the third gear to rotate, which in turn drives the rotating shaft to rotate, which in turn drives the movable ring frame to rotate, and finally drives the cutting mechanism to rotate. By rotating to a specified cutting angle, the steel beam can be cut into the required V-shaped bevel. Then, it can be rotated to a right angle to cut the steel beam into segments. Simultaneously, it can drive the receiving mechanism and the top-loading mechanism to rotate. When cutting the steel beam end face, the receiving mechanism can easily catch the remaining material after cutting, facilitating material transfer. When directly cutting the steel beam, rotating the top-loading mechanism to a horizontal position can hold and fix the steel beam to be cut, improving cutting accuracy.

[0016] Furthermore, the adjustment mechanism includes an adjustment frame slidably connected between the movable ring frame and the limiting ring frame. The front end of the inner surface of the adjustment frame is provided with a sliding groove, which is slidably connected to the outer wall of the movable ring frame. A threaded seat is fixedly connected to the center of the front end of the adjustment frame, and a tightening bolt is threaded into the threaded seat. One end of the tightening bolt is tightly fitted with the movable ring frame. A pointer is fixedly connected to the front end of the adjustment frame near the threaded seat. A limiting wheel is installed at the center of the rear end of the adjustment frame, and the limiting wheel is slidably connected to the annular groove.

[0017] With the above technical solution, when it is necessary to adjust the position of the cutting mechanism, receiving mechanism and top material mechanism, loosen the tightening bolts, slide the adjusting frame, and rotate it to the specified position by observing the scale indicated by the pointer according to the required end face angle. Then tighten the tightening bolts to achieve V-shaped bevels of different angles on the end face of the steel beam. It has strong functionality.

[0018] Furthermore, the cutting mechanism includes a first electric push rod fixedly connected to one of the adjusting frames, a connecting plate fixedly connected to one end of the piston of the first electric push rod, a third motor fixedly mounted on the connecting plate, and a cutting disc fixedly connected to the outer wall of the output shaft of the third motor.

[0019] With the above technical solution, when cutting the steel beam, the third motor is started, and the output shaft rotates to drive the cutting disc to rotate. Then the first electric push rod is started, and the piston pushes the cutting disc to achieve the cutting of the steel beam. The waste generated by cutting falls into the first receiving box, and the cut steel blocks are collected by the receiving mechanism.

[0020] Furthermore, the receiving mechanism includes a second electric push rod fixedly connected to another adjusting frame. One end of the piston of the second electric push rod is fixedly connected to a mounting base. The front and rear ends of the mounting base are provided with circular grooves. Springs are fixedly connected in both circular grooves. Slide rods are fixedly connected to the outer ends of both springs. Electromagnetic blocks are fixedly installed on the outer ends of both slide rods.

[0021] With the above technical solution, when performing V-bevel cutting on the steel beam, the second electric push rod is activated before cutting. The piston pushes the mounting base, thereby moving two electromagnetic blocks. Since the surface edges of the electromagnetic blocks are arc-shaped, both electromagnetic blocks contact the inner end face of the steel beam under the action of springs, achieving magnetic attraction when they are in contact. This not only improves the stability of cutting the steel beam, but also magnetically attracts the cut steel blocks. When the piston of the second electric push rod retracts, the magnetic attraction effect of the electromagnetic blocks is deactivated, allowing the steel blocks to fall into the second receiving box, separating the steel blocks from the waste chips for easy collection by workers. When performing V-bevel cutting on the end face of the steel beam, the lower part is cut first, followed by the upper part. After the lower steel block is cut, the movable ring frame is rotated clockwise, causing the cutting mechanism to rotate to a specified angle. At the same time, another receiving mechanism is rotated to a specified receiving angle, facilitating the magnetic attraction of the other cut steel block. The cutting steps are orderly, resulting in high cutting efficiency.

[0022] Furthermore, the top material mechanism includes two second cylinders fixedly connected to another adjusting frame. The two second cylinders are respectively located on the inner surfaces of the front and rear ends of the adjusting frame, and one end of the piston of each of the two second cylinders is fixedly connected to a top plate.

[0023] With the above technical solution, when cutting the steel beam, the movable ring frame rotates clockwise to turn the cutting mechanism to a vertical angle. At this time, the top material mechanism is exactly flush with the steel beam. Before cutting, the top material mechanism is adjusted by the adjustment mechanism to facilitate automatic rotation to the designated position. The section of the steel beam to be cut is on the conveying component. The two second cylinders are activated, and the pistons push the top plate so that the two top plates are respectively attached to the front and rear ends to be cut, thereby fixing them and improving the stability during cutting. After cutting a section, it is conveyed and transferred by the conveying component.

[0024] The beneficial effects of the present invention are as follows: (1) By designing a rotating mechanism and an adjusting mechanism, the present invention can adjust the cutting disc to a specified angle, thereby cutting V-shaped bevels of various angles on the end face of the steel beam, which is convenient for subsequent welding work; (2) By designing a receiving mechanism and a top-loading mechanism, the present invention can adjust the receiving mechanism and the top-loading mechanism synchronously when the cutting disc is rotated and adjusted, which is convenient for collecting the cut steel blocks, separating the steel blocks from the waste, and clamping and fixing the steel beam at the end that needs to be cut, thereby improving the cutting accuracy; (3) By designing a tightening mechanism and a limiting mechanism, the present invention can tighten the steel beam through the tightening mechanism, which is convenient for moving it and improving the cutting efficiency, and further limit and clamp the steel beam through the limiting mechanism, thereby improving the cutting accuracy.

[0027] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0028] like Figures 1-3As shown, a continuous cutting device for steel beam processing in this embodiment includes a first support frame 1, a base frame 11, and a second support frame 12. A moving mechanism 2 is fixedly installed at the top center of the first support frame 1. The moving mechanism 2 includes a moving frame 201 fixedly connected to the top of the first support frame 1. Multiple rollers 202 are installed on the top of the moving frame 201. Two slide rails 203 are fixedly connected to the top of the moving frame 201. A rack 204 is fixedly connected to the top of the moving frame 201 and located between the two slide rails 203. When cutting the steel beam, the steel beam is placed on the multiple rollers 202 and tightened by the tightening mechanism 3. The other end of the steel beam is pressed by the limiting mechanism 4. The steel beam is cut into small segments in an orderly manner by pushing the tightening mechanism 3. The automatic operation improves the cutting efficiency. A conveying assembly 10 is fixedly installed on the top of the second support frame 12. A first receiving box 13 and a second receiving box 14 are provided in the base frame 11.

[0029] like Figures 1-6As shown, the moving mechanism 2 is equipped with a tightening mechanism 3. The tightening mechanism 3 includes two slide blocks 301 slidably connected to two slide rails 203. A moving plate 302 is fixedly connected to the top of the two slide blocks 301. A first motor 303 is fixedly installed on one side of the top of the moving plate 302. A first gear 304 is fixedly connected to the outer wall of the output shaft of the first motor 303. A first fixing frame 305 is fixedly connected to the top of one side of the moving plate 302. A first threaded groove 306 is provided at the top center of the first fixing frame 305. A threaded rod 307 is threadedly connected to the first threaded groove 306. A limit rod 308 is fixedly connected to the bottom end of the threaded rod 307. The bottom of the fixing frame 305 is rotatably connected to the bottom end of the first threaded groove 306, and a limiting cylinder 309 is rotatably connected to the outer wall of the limiting cylinder 309. A first bevel gear 310 is fixedly connected to the outer wall of the first fixing frame 305. Rotating rods 311 are rotatably connected to the front and rear ends of the first fixing frame 305. A second threaded groove 312 is opened on the outer wall of each of the two rotating rods 311. A second bevel gear 313 is fixedly connected to the inner end of the outer wall of each of the two rotating rods 311. Threaded cylinders 314 are threaded to each of the two rotating rods 311 through the second threaded grooves 312. Expansion plates 315 are fixedly connected to the outer ends of each of the two threaded cylinders 314. Limiting strips 316 are fixedly connected to the bottom end of the outer wall of each of the two threaded cylinders 314. The first fixed frame 305 has limiting grooves 317 at both the front and rear ends of its top. When tightening the steel beam, one end face of the moving plate 302 is attached to one end of the steel beam. Rotating the threaded rod 307 causes the limiting rod 308 to rotate, which in turn causes the limiting cylinder 309 and the first bevel gear 310 to rotate, which in turn causes the two second bevel gears 313 to rotate, all of which cause the connected threaded cylinder 314 to rotate. Under the action of the corresponding limiting strip 316 and limiting groove 317, the threaded cylinder 314 moves outward, thereby causing the two tightening plates 315 to adhere to the inner walls of the front and rear ends of the steel beam. When the threaded rod 307 is tightened, the two tightening plates 315 tighten the steel beam. The steel beam is tightened to fix it during cutting, improving cutting accuracy. The first gear 304 meshes with the rack 204, the limiting rod 308 passes through the limiting cylinder 309, the first bevel gear 310 meshes with two second bevel gears 313, and the two limiting strips 316 are slidably connected to the corresponding limiting grooves 317. When the steel beam needs to be cut, the first motor 303 is started, which drives the first gear 304 to mesh and rotate on the rack 204 through the output shaft, thereby driving the entire moving plate 302 to move, realizing the movement of the steel beam, which facilitates the subsequent cutting mechanism 7 to cut it. The automation effect is strong, improving the cutting efficiency of the steel beam.

[0030] like Figures 1-7As shown, a limiting mechanism 4 is fixedly connected to the top of the first support frame 1 near the base frame 11. The limiting mechanism 4 includes a frame 401 fixedly connected to one side of the top of the first support frame 1. A first cylinder 402 is fixedly installed on the top and front and rear ends of one side of the frame 401. A wheel frame 403 is fixedly connected to one end of the piston of each of the first cylinders 402. A pulley 404 is installed on each of the wheel frames 403. When cutting the steel beam, the first cylinders 402 are activated. The first cylinders 402 push the connected pulleys 404 through the piston, so that the pulleys 404 contact the steel beam. Two pulleys 404 press against the front and rear ends of the steel beam respectively, and the other pulley 404 presses against the top of the steel beam, so that the steel beam has a certain stability during movement, thereby greatly improving the cutting accuracy.

[0031] like Figures 1-10 As shown, a rotating mechanism 5 is fixedly connected to the top of the base frame 11. The rotating mechanism 5 includes two second fixed frames 501 fixedly connected to the top of the base frame 11. A rotating shaft 502 is rotatably connected to the center of one of the second fixed frames 501. A movable ring frame 503 is fixedly connected to the rear end of the outer wall of the rotating shaft 502. A scale 504 is provided at the front end of the movable ring frame 503. A third gear 505 is fixedly connected to the front end of the outer wall of the rotating shaft 502. A second motor 506 is fixedly installed at the front end of one of the second fixed frames 501. A fourth gear 507 is fixedly connected to the outer wall of the output shaft of the second motor 506. The fourth gear 507 meshes with the third gear 505. A limiting ring frame 508 is fixedly connected to the center of the other second fixed frame 501. A ring is provided at the front end of the limiting ring frame 508. When the steel beam end face needs to be cut into a V-shaped bevel, the second motor 506 is started, which drives the fourth gear 507 to rotate through the output shaft, thereby driving the third gear 505 to rotate, which in turn drives the rotating shaft 502 to rotate, which in turn drives the movable ring frame 503 to rotate, which in turn drives the cutting mechanism 7 to rotate. By rotating to a specified cutting angle, the steel beam can be cut into the required V-shaped bevel. Then it can be rotated to a right angle to cut the steel beam into segments. At the same time, it can drive the receiving mechanism 8 and the top material mechanism 9 to rotate. When cutting the end face of the steel beam, the receiving mechanism 8 can be used to catch the leftover material after cutting, which is convenient for transferring the material. When directly cutting the steel beam, the top material mechanism 9 can be rotated to a horizontal position to hold and fix the steel beam to be cut, thereby improving the cutting accuracy.

[0032] like Figures 1-11As shown, the rotating mechanism 5 is equipped with multiple adjusting mechanisms 6. Each adjusting mechanism 6 includes an adjusting frame 601 slidably connected between the movable ring frame 503 and the limiting ring frame 508. A groove 602 is formed at the front end of the inner surface of the adjusting frame 601, and the groove 602 is slidably connected to the outer wall of the movable ring frame 503. A threaded seat 603 is fixedly connected to the center of the front end of the adjusting frame 601. A tightening bolt 604 is threaded into the threaded seat 603, and one end of the tightening bolt 604 is tightly fitted to the movable ring frame 503. The front end of the adjusting frame 601 is close to the threaded seat. A pointer 605 is fixedly connected to position 603. A limit wheel 606 is installed at the rear center of the adjusting frame 601. The limit wheel 606 is slidably connected to the annular groove 509. When it is necessary to adjust the position of the cutting mechanism 7, the receiving mechanism 8, and the top material mechanism 9, loosen the tightening bolt 604, slide the adjusting frame 601, and rotate it to the specified position by observing the scale 504 specified by the pointer 605 according to the required end face angle. Then tighten the tightening bolt 604 to achieve V-shaped bevels of different angles on the end face of the steel beam. It has strong functionality.

[0033] The top of each of the multiple adjustment mechanisms 6 is respectively equipped with a cutting mechanism 7, two receiving mechanisms 8, and a top material mechanism 9. The cutting mechanism 7 includes a first electric push rod 701 fixedly connected to one of the adjustment frames 601. One end of the piston of the first electric push rod 701 is fixedly connected to a connecting plate 702. A third motor 703 is fixedly installed on the connecting plate 702. A cutting disc 704 is fixedly connected to the outer wall of the output shaft of the third motor 703. When cutting the steel beam, the third motor 703 is started, and the output shaft rotates to drive the cutting disc 704 to rotate. Then the first electric push rod 701 is started, and the piston pushes the cutting disc 704 to achieve the cutting of the steel beam. The waste generated by cutting falls into the first receiving box 13, and the cut steel blocks are collected by the receiving mechanism 8.

[0034] like Figures 1-12As shown, the receiving mechanism 8 includes a second electric push rod 801 fixedly connected to another adjusting frame 601. One end of the piston of the second electric push rod 801 is fixedly connected to a mounting base 802. The mounting base 802 has circular grooves 803 at both its front and rear ends. Springs 806 are fixedly connected to both circular grooves 803. Slide rods 804 are fixedly connected to the outer ends of both springs 806. Electromagnetic blocks 805 are fixedly installed on the outer ends of both slide rods 804. When performing V-bevel cutting on the steel beam, the second electric push rod 801 is activated before cutting, pushing the mounting base 802 through the piston, thereby moving the two electromagnetic blocks 805. Because the surface edges of the electromagnetic blocks 805 are arc-shaped, the two electromagnetic blocks 805... All contacts the inner end face of the steel beam under the action of spring 806, achieving magnetic attraction when in contact. This not only improves the stability of cutting the steel beam, but also magnetically holds the cut steel blocks. When the piston of the second electric push rod 801 retracts, the electromagnetic block 805 closes the magnetic attraction effect, causing the steel blocks to fall into the second receiving box 14, separating the steel blocks from the waste and facilitating collection by the staff. When cutting the V-shaped bevel of the steel beam end face, the lower part is cut first, followed by the upper part. After the lower steel block is cut, the movable ring frame 503 is rotated clockwise, causing the cutting mechanism 7 to rotate to the specified angle. At the same time, another receiving mechanism 8 is rotated to the specified angle for receiving, thus facilitating the magnetic attraction of the other cut steel block. The cutting steps are orderly, resulting in high cutting efficiency.

[0035] like Figures 1-13 As shown, the top material mechanism 9 includes two second cylinders 901 fixedly connected to another adjusting frame 601. The two second cylinders 901 are located on the inner surfaces of the front and rear ends of the adjusting frame 601, respectively. One end of the piston of each of the two second cylinders 901 is fixedly connected to a top plate 902. When cutting the steel beam, the movable ring frame 503 rotates clockwise to rotate the cutting mechanism 7 to a vertical angle. At this time, the top material mechanism 9 is exactly flush with the steel beam. Before cutting, the top material mechanism 9 is adjusted by the adjusting mechanism 6, which is to facilitate automatic rotation to the designated position later. The section of the steel beam to be cut is on the conveying component 10. The two second cylinders 901 are started, and the pistons push the top plate 902, so that the two top plates 902 are respectively attached to the front and rear ends to be cut, thereby fixing them and improving the stability during cutting. After cutting a section, it is conveyed and transferred by the conveying component 10.

[0036] The working principle of this embodiment is as follows: Before cutting, adjust the specific positions of the cutting mechanism 7, the receiving mechanism 8 and the top material mechanism 9 according to the required V-shaped bevel angle of the steel beam, loosen the tightening bolt 604, slide the adjusting bracket 601, and rotate the end face angle to the specified position by observing the scale 504 specified by the pointer 605 according to the required cutting angle, and then tighten the tightening bolt 604, thereby adjusting the cutting mechanism 7, the two receiving mechanisms 8 and the top material mechanism 9 to the specified position; Next, place the steel beam on multiple rollers 202, and align one end face of the moving plate 302 with one end of the steel beam. Rotate the threaded rod 307, thereby driving the limiting rod 308 to rotate, which in turn drives the limiting cylinder 309 and the first bevel gear 310 to rotate, which in turn drives the two second bevel gears 313 to rotate, all of which drive the connected threaded cylinder 314 to rotate. Under the action of the corresponding limiting strip 316 and limiting groove 317, the threaded cylinder 314 moves outward, thereby driving the two expansion plates 315 to adhere to the inner walls of the front and rear ends of the steel beam. When the threaded rod 307 is tightened, the steel beam is expanded and tightened through the two expansion plates 315, thereby fixing the steel beam during cutting. When one end of the steel beam is moved to the cutting position, multiple first cylinders 402 are activated. Each of the multiple first cylinders 402 pushes the connected pulleys 404 through the piston, so that multiple pulleys 404 contact the steel beam. Two of the pulleys 404 press against the front and rear ends of the steel beam respectively, while the other pulley 404 presses against the top of the steel beam, so that the steel beam has a certain stability during the movement. When cutting the end face of the steel beam into a V-shaped bevel, following the sequence of cutting down first and then cutting up, the second motor 506 is started, which drives the fourth gear 507 to rotate via the output shaft, thereby driving the third gear 505 to rotate, which in turn drives the rotating shaft 502 to rotate, which in turn drives the movable ring frame 503 to rotate, thereby driving the cutting mechanism 7 to rotate to the specified cutting angle (at this time, the lower left of the end face of the steel beam). At the same time, the corresponding receiving mechanism 8 rotates to the lower right side, first starting the second electric push rod 801, which pushes the mounting base 802 via the piston, thereby driving the two electromagnetic blocks 805 to move. Since the surface edge of the electromagnetic block 805 is arc-shaped... The two electromagnetic blocks 805 are brought into contact with the inner end face of the steel beam under the action of the spring 806, and magnetic attraction is achieved when they are in contact. Then the third motor 703 is started, and the output shaft rotates to drive the cutting disk 704 to rotate. Then the first electric push rod 701 is started, and the piston pushes the cutting disk 704 to achieve the cutting of the end face of the steel beam. The waste generated by cutting falls into the first receiving box 13. The cut steel blocks are magnetically attracted by the corresponding receiving mechanism 8. When the piston of the second electric push rod 801 is retracted, the electromagnetic block 805 closes the magnetic attraction effect, so that the steel blocks fall into the second receiving box 14, thus separating the steel blocks from the waste. First, the steel beam is pulled by the tensioning mechanism 3 to give the cutting mechanism 7 room to rotate. Then, the rotating mechanism 5 is rotated clockwise to rotate the cutting mechanism 7 to the specified cutting angle (at this time, it is the upper left of the steel beam end face). At the same time, the corresponding receiving mechanism 8 is rotated to the upper right side. In the same way, another steel block is cut out from the steel beam end face, thus completing the V-shaped bevel cutting of the steel beam end face. Finally, when the steel beam is cut into sections, the rotating mechanism 5 is rotated clockwise to rotate the cutting mechanism 7 to a vertical angle (at which point it is directly above the end face of the steel beam). At this time, the top material mechanism 9 is flush with the steel beam. Then, the expansion mechanism 3 pushes the steel beam to push the section to be cut onto the conveying assembly 10. The two second cylinders 901 are activated, and both push the top plate 902 through the piston, so that the two top plates 902 are respectively attached to the front and rear ends to be cut, thereby fixing them and improving the stability during cutting. After a section is cut, it is conveyed and transferred by the conveying assembly 10. The same principle can be used to cut the steel beam into sections, with each section having a designed V-shaped bevel at one end to facilitate subsequent welding.
