Description

Technical Field

[0001] The present invention relates to the technical field of welding equipment, and particularly to a welding equipment and a using method for the forming and processing of a lightweight machine tool frame. Background Art

[0002] With the continuous improvement of the requirements for machining accuracy, speed and efficiency in the manufacturing industry, lightweight machine tool frames help to reduce the inertia of moving parts, thereby achieving faster start and stop and higher motion accuracy, and improving the dynamic performance of machine tools. As the supporting structure of machine tools, machine tool frames need to have properties such as high precision, high rigidity, good stability and vibration resistance. These properties directly affect the machining accuracy, surface quality and production efficiency of machine tools. With the continuous improvement of the requirements for machine tool accuracy, efficiency and reliability in the manufacturing industry, the welding technology of machine tool frames is also constantly developing and innovating.

[0003] During the working process of existing welding equipment, different welding positions and joint forms require different tilting angles of the welding torch to ensure the formation of welds. If the welding torch cannot be tilted, the weld metal may not be evenly distributed on both sides of the joint, resulting in irregular weld shapes and poor fusion on both sides, affecting the appearance quality and strength of the weld. Summary of the Invention

[0004] To achieve the above objectives, the present invention is realized through the following technical solutions: a welding equipment and a using method for the forming and processing of a lightweight machine tool frame, including a platform, and a guide rail fixedly installed on the top of the platform. A slider is slidably connected to the side of the guide rail. A side plate is fixedly connected to the outside of the slider. A top plate is fixedly connected to the top of the side plate. A square hole is opened in the middle of the top of the top plate. A screw rod is rotatably connected to the inside of the square hole. There are two sliders, and the two sliders are symmetrically arranged with the guide rail as the center. There are two side plates, and both ends of the top plate are fixedly connected to the two side plates on both sides respectively;

[0005] A fixing component, which is fixedly installed in the middle of the top of the guide rail;

[0006] A welding component, which is slidably connected to the top plate and is also slidably connected to the screw rod;

[0007] Among them, the welding assembly includes a moving block. A through hole is provided inside the moving block, and a screw rod passes through the moving block through the through hole. An extension block is fixedly connected to the outside of the moving block, and a hydraulic cylinder is fixedly connected to the top of the extension block. Place the material to be processed above the fixing assembly. The slider drives the side plate and the top plate to move to the specified position. Subsequently, the hydraulic cylinder works to drive the fixing plate to move downward, so that the fixing plate drives the guide rod to move downward, and the welding part at the bottom of the fixing plate moves to the specified position. According to the actual situation, the motor is externally powered to work. The motor drives the welding part to rotate, so that the welding part rotates inside the through groove, thereby adjusting the welding angle of the welding part to make the welding part in a suitable welding angle for welding operation. By adjusting the appropriate angle, the molten pool metal can better fill the weld under the action of gravity, so that better connection and fusion between each weld can be achieved, forming a uniform and beautiful weld formation. At the same time, during the welding process, heat can be more evenly distributed on both sides of the weld, avoiding uneven expansion and contraction caused by local overheating. The output end of the hydraulic cylinder is fixedly connected to a fixing plate, a semi-circular plate is fixedly connected to the bottom of the fixing plate, a welding part is rotatably connected to the middle of the bottom of the semi-circular plate, a motor is fixedly connected to the outside of the semi-circular plate, and the output end of the motor is fixedly connected to the welding part.

[0008] Preferably, the moving block is slidably connected to the square hole. The output end of the hydraulic cylinder passes through the extension block. A guide rod is fixedly connected to the top of the fixing plate. By setting the guide rod, it can provide precise guidance for the movement of the welding part, limit the lateral shaking and deviation of the welding part during the movement, thereby improving the positioning accuracy of the welding part. This is very important for ensuring the accuracy of the welding position, helping to improve the welding quality and reducing weld defects caused by the position deviation of the welding part. The number of guide rods is multiple, and the multiple guide rods are evenly distributed at the corners of the fixing plate. The guide rod is slidably connected to the extension block. A ring groove is provided on the outside of the semi-circular plate, the ring groove penetrates the semi-circular plate, a through groove is provided at the bottom of the semi-circular plate, the through groove is perpendicular to the ring groove, the welding part is slidably connected to the semi-circular plate, and a limiting part is fixedly connected to the outside of the welding part away from the semi-circular plate.

[0009] Preferably, the welding part includes a fixing block located inside the through groove. The fixing block is slidably connected to the semi-circular plate through the inner wall of the through groove. A welding torch is fixedly connected to the bottom of the fixing block, and a connecting seat is fixedly connected to the top of the fixing block. The motor works with an external power supply. When the motor works, it drives the connecting seat to rotate, so that the connecting seat drives the fixing block and the welding torch to rotate. Thus, the round rod slides on the inner wall of the annular groove, thereby adjusting the angle of the welding torch. By setting the annular groove, a clear moving track is provided for the welding torch, which can ensure that the welding torch always advances along the predetermined welding position, thereby ensuring the position accuracy of the weld, helping to improve the consistency and repeatability of welding, reducing welding deviations caused by human factors, and at the same time reducing the time for frequently adjusting the position and angle of the welding torch during manual operation, improving the welding speed, and further enhancing the overall welding efficiency. A round rod is fixedly connected to the outside of the fixing block. The number of round rods is two, and the two round rods are symmetrically arranged with the fixing block as the center. The round rod is perpendicular to the connecting seat. The round rod is located inside the annular groove. One end of the round rod far from the fixing block is fixedly connected to a round plate, and an annular frame is fixedly connected to the outside of the end of the welding torch far from the fixing block.

[0010] Preferably, the limiting part includes a fixing ring fixedly connected to the welding torch. The fixing ring is sleeved on the outside of the end of the welding torch far from the fixing block. Two rotating rods are rotatably connected to the outside of the fixing ring. The two rotating rods are symmetrically arranged with the fixing ring as the center. One end of the rotating rod far from the fixing ring is fixedly connected to a rotating plate. The motor works with an external power supply. When the motor works, it drives the welding torch to rotate through the connecting seat, thereby adjusting the angle of the welding torch. As the welding torch tilts, the rotating plate and the semi-circular plate are connected by a connecting rod. Under the action of gravity, the round rod rotates relative to the fixing ring, so that the round rod slides inside the annular frame, ensuring that the elastic plate is always in the vertical direction. The hydraulic cylinder works to drive the fixing plate to move downward, so that the fixing plate drives the welding torch and the elastic plate to move downward, so that the bottom elastic plate is in close contact with both sides of the welding part of the material, making the welding torch flush with the welding part, avoiding the deviation of the welding torch during the welding process, which may lead to poor welding quality. One end of the rotating plate far from the rotating rod is fixedly connected to a cylinder located inside the annular frame. The cylinder is slidably connected to the annular frame. An elastic plate is fixedly connected to the side of the rotating plate far from the rotating rod. A connecting rod is fixedly connected to the top of the rotating plate. One end of the connecting rod far from the rotating plate is fixedly connected to the middle of the bottom of the semi-circular plate.

[0011] Preferably, the fixing component includes a limiting plate fixedly installed at the middle of the top of the guide rail. A motor is fixedly connected to the outside of the limiting plate. An arc plate is fixedly connected to the middle of the top of the limiting plate. An elastic plate is fixedly connected to the inner wall of the arc plate. The elastic plate supports the material at the welding joint. When the welding component moves downward, it generates extrusion with the top of the material. The spring plate and the elastic plate can play a role in positioning and clamping. They can fix the position of the welding joint, prevent shaking or deviation during the welding process, and ensure the accuracy and consistency of welding. Since the material may be affected by factors such as welding stress and thermal deformation during the welding process, an elastic plate is arranged near the bottom of the welding joint, which can buffer these external forces to a certain extent, reduce the direct action on the material, prevent defects such as deformation and cracking of the material due to excessive local stress, and protect the integrity and performance of the material. There are two elastic plates, and the two elastic plates are symmetrically arranged inside the arc plate. A sliding groove is formed in the top of the limiting plate. A threaded rod is rotatably connected to the inside of the sliding groove. The threaded rod is fixedly connected to the output end of the motor. A fixing part is slidably connected to the inner wall of the sliding groove. The motor is powered on to work. The motor drives the threaded rod to rotate. The threaded rod rotates to drive the fixing part to move. By adjusting the distance between the two fixing parts on both sides, the two sides of the material to be processed can be closely attached, realizing precise positioning and limiting, ensuring that the material will not move horizontally during use, improving the working precision and stability. At the same time, it can also be adjusted according to materials of different sizes, increasing the versatility and flexibility of the device, reducing the trouble of replacing different fixing devices due to changes in material sizes, reducing costs, and the threaded rod is rotatably connected to the fixing part.

[0012] Preferably, the fixing member includes a square block which is rotatably connected to the threaded rod and slidably connected to the inner wall of the sliding groove. A connecting block is fixedly connected to the top of the square block, and a fixing seat is fixedly connected to the top of the connecting block. A positioning block is rotatably connected to the top of the fixing seat, and an inclined plate is fixedly connected to the top of the positioning block. An electric push rod is fixedly connected to the top of the end of the connecting block away from the fixing seat. According to the actual processed material, the motor works to drive the threaded rod to rotate, so that the square block drives the connecting block to move to a specified position. Then the material is placed in the space between the two inclined plates. Under the elastic force of the return spring between the two inclined plates, the middle plate drives the middle rod to rotate, so that the top inclined plate moves downward under force, and at this time the two side inclined plates are in close contact with the material in the middle, thereby fixing the material. Subsequently, the electric push rod works to drive the inclined plate to rotate between the fixing seat and the positioning block, so as to adjust the inclination direction of the inclined plate. Adjusting the inclination angle of the inclined plate can make the gravity or external force of the object more evenly distributed on the inclined plate, avoid excessive local stress, and effectively reduce the stress concentration phenomenon at the fixing point of the object. This helps to extend the service life of the object and the fixing member and reduce the risk of structural damage caused by stress concentration. The output end of the electric push rod is fixedly connected to the end of the inclined plate away from the positioning block. A middle rod is rotatably connected to the inside of the inclined plate. The number of middle rods is two, and the two middle rods are symmetrically arranged at both ends of the inclined plate. The end of the middle rod is fixedly connected to a middle plate. The two inclined plates and the two middle plates form a parallelogram. The number of inclined plates is two, and the two inclined plates are symmetrically arranged with the middle plate as the center. A return spring is fixedly connected to the outer edge of the inclined plate, and both ends of the return spring are fixedly connected to the two inclined plates respectively. A notch is formed on the outer side of the inclined plate, and a baffle is rotatably connected to the outer side of the inclined plate. The baffles are symmetrically arranged at both ends of the inclined plate and are located in the space between the two inclined plates. A middle column is fixedly connected to the side of the baffle close to the inclined plate. The material is placed in the space between the two inclined plates. At this time, the side of the material contacts and is squeezed by the two baffles. Under the elastic force of the compression spring, the baffle drives the middle column to slide inside the notch, so that the material is located in the middle of the inclined plate, making the welding joints aligned. The middle column is located inside the notch, and the middle column passes through the inclined plate through the notch. A middle block is fixedly connected to the end of the middle column away from the baffle, and a compression spring is fixedly connected to the outer side of the middle block. Both ends of the compression spring are fixedly connected to the two middle blocks.

[0013] A welding method for forming a lightweight machine tool frame includes the following steps:

[0014] S1. Adjust the equipment. The motor works to drive the threaded rod to rotate, so that the square block drives the connecting block to move to a specified position;

[0015] S2. Fix the material. Place the material in the space between the two inclined plates. Under the elastic force of the return spring between the two inclined plates, the two side inclined plates are in close contact with the material in the middle;

[0016] S3. Adjust the angle. The motor is externally powered and operates. The motor drives the welding torch to rotate through the connecting seat, thereby adjusting the angle of the welding torch.

[0017] S4. Weld the material. The hydraulic cylinder operates to drive the fixed plate to move downward, causing the fixed plate to drive the guide rod to move downward, and enabling the welding part at the bottom of the fixed plate to move to the designated position, thereby welding the material.

[0018] The present invention provides a welding device and a usage method for the forming and processing of a lightweight machine tool frame, which have the following beneficial effects:

[0019] First, for the welding device and the usage method for the forming and processing of the lightweight machine tool frame, by rotating the welding part inside the through groove, the welding angle of the welding part is adjusted, so that the welding part is at a suitable welding angle, facilitating the welding operation. By adjusting the appropriate angle, the molten pool metal can better fill the weld seam under the action of gravity, thereby better achieving good connection and fusion between each weld seam and forming a uniform and beautiful weld seam formation.

[0020] Second, for the welding device and the usage method for the forming and processing of the lightweight machine tool frame, since the elastic plate is always in the vertical direction, when the hydraulic cylinder operates to drive the fixed plate to move downward, the fixed plate drives the welding torch and the elastic plate to move downward, so that the bottom elastic plate is in close contact with both sides of the welding part of the material, making the welding torch flush with the welding part, avoiding the deviation of the welding torch during the welding process, which may lead to poor welding quality.

[0021] Third, for the welding device and the usage method for the forming and processing of the lightweight machine tool frame, by arranging the elastic plate near the welding part at the bottom, these external forces can be buffered to a certain extent, reducing the direct action on the material, preventing defects such as deformation and cracking of the material due to excessive local stress, and protecting the integrity and performance of the material.

[0022] Fourth, for the welding device and the usage method for the forming and processing of the lightweight machine tool frame, by adjusting the distance between the two fixing parts on both sides, the two sides of the material to be processed can be closely fitted, achieving precise positioning and limiting, ensuring that the material will not move laterally during use, and improving the accuracy and stability of the work.

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] The first embodiment, as Figures 1 to 4As shown in the figure, the present invention provides a technical solution: a welding device and a using method for forming a lightweight machine tool frame, including a platform 1 and a guide rail 2 fixedly installed on the top of the platform 1.

The number of side plates 6 is two, and both ends of the top plate 7 are fixedly connected to the two side plates 6 on both sides;

[0035] A fixing component 3 is fixedly installed in the middle of the top of the guide rail 2;

[0036] A welding component 4 is slidably connected to the top plate 7 and is also slidably connected to the screw rod 9;

[0037] Among them, the welding component 4 includes a moving block 41. A through hole 45 is opened inside the moving block 41. The screw rod 9 passes through the moving block 41 through the through hole 45. An extension block 42 is fixedly connected to the outside of the moving block 41. A hydraulic cylinder 43 is fixedly connected to the top of the extension block 42. Place the material to be processed above the fixing component 3. The slider 5 drives the side plate 6 and the top plate 7 to move to the designated position. Subsequently, the hydraulic cylinder 43 works to drive the fixing plate 44 to move downward, so that the fixing plate 44 drives the guide rod 47 to move downward, and the welding part 49 at the bottom of the fixing plate 44 moves to the designated position. According to the actual situation, the motor 411 is externally powered to work. The motor 411 works to drive the welding part 49 to rotate, so that the welding part 49 rotates inside the through groove 412, thereby adjusting the welding angle of the welding part 49 to make the welding part 49 in a suitable welding angle, facilitating the welding operation. By adjusting the appropriate angle, the molten pool metal can better fill the weld under the action of gravity, so that better connection and fusion between each weld can be achieved, forming a uniform and beautiful weld formation. At the same time, during the welding process, heat can be more evenly distributed on both sides of the weld, avoiding uneven expansion and contraction caused by local overheating. The output end of the hydraulic cylinder 43 is fixedly connected to a fixing plate 44. A semi-circular plate 48 is fixedly connected to the bottom of the fixing plate 44. A welding part 49 is rotatably connected to the middle of the bottom of the semi-circular plate 48. A motor 411 is fixedly connected to the outside of the semi-circular plate 48. The output end of the motor 411 is fixedly connected to the welding part 49.

[0038] The second embodiment, on the basis of the first embodiment, please refer to Figures 3 to 5As shown, the moving block 41 is slidably connected to the square hole 8. The output end of the hydraulic cylinder 43 penetrates through the extension block 42. A guide rod 47 is fixedly connected to the top of the fixing plate 44. By providing the guide rod 47, it can provide precise guidance for the movement of the welded part 49, restrict the lateral sway and deviation of the welded part 49 during movement, thereby improving the positioning accuracy of the welded part 49, which is very important for ensuring the accuracy of the welding position, helps to improve the welding quality, and reduces the weld defects caused by the position deviation of the welded part. There are multiple guide rods 47, and the multiple guide rods 47 are evenly distributed at the corners of the fixing plate 44. The guide rod 47 is slidably connected to the extension block 42. A ring groove 410 is provided on the outer side of the semi-circular plate 48, and the ring groove 410 penetrates through the semi-circular plate 48. A through groove 412 is provided at the bottom of the semi-circular plate 48, and the through groove 412 is perpendicular to the ring groove 410. The welded part 49 is slidably connected to the semi-circular plate 48, and a limiting part 46 is fixedly connected to the outer side of the welded part 49 away from the semi-circular plate 48.

[0039] The welded part 49 includes a fixed block 491. The fixed block 491 is located inside the through groove 412. The fixed block 491 is slidably connected to the semi-circular plate 48 through the inner wall of the through groove 412. A welding torch 495 is fixedly connected to the bottom of the fixed block 491. A connecting seat 492 is fixedly connected to the top of the fixed block 491. The motor 411 operates with an external power supply. When the motor 411 operates, it drives the connecting seat 492 to rotate, so that the connecting seat 492 drives the fixed block 491 and the welding torch 495 to rotate. Thus, the round rod 493 slides on the inner wall of the ring groove 410, thereby adjusting the angle of the welding torch 495. By providing the ring groove 410, it provides a clear movement track for the welding torch 495, can ensure that the welding torch 495 always advances along the predetermined welding position, thereby ensuring the position accuracy of the weld, helps to improve the consistency and repeatability of welding, reduces the welding deviation caused by human factors, and at the same time reduces the time for frequently adjusting the position and angle of the welding torch during manual operation, improves the welding speed, and further improves the overall welding efficiency. There are two round rods 493 fixedly connected to the outer side of the fixed block 491. The two round rods 493 are symmetrically arranged with the fixed block 491 as the center. The round rod 493 is perpendicular to the connecting seat 492. The round rod 493 is located inside the ring groove 410. A round plate 494 is fixedly connected to one end of the round rod 493 away from the fixed block 491. An annular frame 496 is fixedly connected to the outer side of one end of the welding torch 495 away from the fixed block 491.

[0040] The third embodiment is based on the first and second embodiments. Please refer to Figure 5As shown in the figure, the limiting member 46 includes a fixing ring 461. The fixing ring 461 is fixedly connected to the welding torch 495. The fixing ring 461 is sleeved on the outer side of the end of the welding torch 495 far from the fixing block 491. A rotating rod 462 is rotatably connected to the outer side of the fixing ring 461. The number of the rotating rods 462 is two, and the two rotating rods 462 are symmetrically arranged with the fixing ring 461 as the center. A rotating plate 463 is fixedly connected to the end of the rotating rod 462 far from the fixing ring 461. The motor 411 operates with an external power supply. The motor 411 drives the welding torch 495 to rotate through the connecting seat 492, so as to adjust the angle of the welding torch 495. As the welding torch 495 tilts, the rotating plate 463 and the semi-circular plate 48 are connected by the connecting rod 466. Under the action of gravity, the round rod 493 rotates relative to the fixing ring 461, so that the cylinder 464 of the round rod 493 slides inside the annular frame 496, making the elastic plate 465 always in the vertical direction. The hydraulic cylinder 43 operates to drive the fixing plate 44 to move downward, so that the fixing plate 44 drives the welding torch 495 and the elastic plate 465 to move downward, so that the elastic plate 465 at the bottom is in close contact with both sides of the welding part of the material, making the welding torch 495 flush with the welding part, avoiding the deviation of the welding torch 495 during the welding process, which may lead to poor welding quality. A cylinder 464 is fixedly connected to the end of the rotating plate 463 far from the rotating rod 462. The cylinder 464 is located inside the annular frame 496. The cylinder 464 is slidably connected to the annular frame 496. An elastic plate 465 is fixedly connected to the side of the rotating plate 463 far from the rotating rod 462. A connecting rod 466 is fixedly connected to the top of the rotating plate 463. The end of the connecting rod 466 far from the rotating plate 463 is fixedly connected to the middle of the bottom of the semi-circular plate 48.

[0041] For the fourth embodiment, please refer to Figures 6 to 9As shown, the fixing component 3 includes a limiting plate 31 which is fixedly installed at the middle of the top of the guide rail 2. A motor 33 is fixedly connected to the outside of the limiting plate 31. At the middle of the top of the limiting plate 31, an arc plate 37 is fixedly connected. An elastic plate 32 is fixedly connected to the inner wall of the arc plate 37. The elastic plate 32 supports the material at the welding joint. When the welding component 4 moves downward, extrusion is generated between it and the top of the material. The elastic plate 465 and the elastic plate 32 can play a role in positioning and clamping. They can fix the position of the welding joint, prevent shaking or deviation during the welding process, and ensure the accuracy and consistency of welding. Since the material may be affected by factors such as welding stress and thermal deformation during the welding process, the elastic plate 32 is arranged at the bottom near the welding joint, which can buffer these external forces to a certain extent, reduce the direct action on the material, prevent defects such as deformation and cracking of the material due to excessive local stress, and protect the integrity and performance of the material. There are two elastic plates 32, and the two elastic plates 32 are symmetrically arranged inside the arc plate 37. A sliding groove 34 is opened at the top of the limiting plate 31. A threaded rod 35 is rotatably connected inside the sliding groove 34. The threaded rod 35 is fixedly connected to the output end of the motor 33. A fixing member 36 is slidably connected to the inner wall of the sliding groove 34. The motor 33 is powered by an external power supply. When the motor 33 works, it drives the threaded rod 35 to rotate. The rotation of the threaded rod 35 drives the fixing member 36 to move. By adjusting the distance between the two fixing members 36 on both sides, the two sides of the material to be processed can be closely fitted, realizing accurate positioning and limiting, ensuring that the material will not move horizontally during use, improving the working precision and stability. At the same time, it can also be adjusted according to materials of different sizes, increasing the versatility and flexibility of the device, reducing the trouble of replacing different fixing devices due to changes in material sizes, and reducing costs. The threaded rod 35 is rotatably connected to the fixing member 36.

[0042] The fixing member 36 includes a square block 361. The square block 361 is rotatably connected to the threaded rod 35 and slidably connected to the inner wall of the sliding groove 34. A connecting block 362 is fixedly connected to the top of the square block 361, and a fixing seat 363 is fixedly connected to the top of the connecting block 362. A positioning block 364 is rotatably connected to the top of the fixing seat 363, and an inclined plate 365 is fixedly connected to the top of the positioning block 364. An electric push rod 366 is fixedly connected to the top of the connecting block 362 away from the fixing seat 363. According to the actual processed material, the motor 33 works to drive the threaded rod 35 to rotate, so that the square block 361 drives the connecting block 362 to move to a specified position. Then the material is placed in the space between the two inclined plates 365. Under the elastic force of the return spring 3611 between the two inclined plates 365, the middle plate 367 drives the middle rod 368 to rotate, so that the top inclined plate 365 is forced to move downward. At this time, the two side inclined plates 365 are in close contact with the material in the middle, so as to fix the material. Subsequently, the electric push rod 366 works to drive the inclined plate 365 to rotate between the fixing seat 363 and the positioning block 364, so as to adjust the inclination direction of the inclined plate 365. Adjusting the inclination angle of the inclined plate 365 can make the gravity or external force of the object more evenly distributed on the inclined plate 365, avoid excessive local stress, and effectively reduce the stress concentration phenomenon at the fixing point of the object. This helps to extend the service life of the object and the fixing member and reduce the risk of structural damage caused by stress concentration. The output end of the electric push rod 366 is fixedly connected to the end of the inclined plate 365 away from the positioning block 364. A middle rod 368 is rotatably connected to the inside of the inclined plate 365.

The number of the inclined plates 365 is two, and the two inclined plates 365 are symmetrically arranged with the middle plate 367 as the center. A return spring 3611 is fixedly connected to the outer edge of the inclined plate 365, and both ends of the return spring 3611 are fixedly connected to the two inclined plates 365 respectively. A notch 3612 is formed in the outer side of the inclined plate 365, and a baffle 3613 is rotatably connected to the outer side of the inclined plate 365. The baffles 3613 are symmetrically arranged at both ends of the inclined plate 365 and are located in the space between the two inclined plates 365. A middle column 3614 is fixedly connected to the side of the baffle 3613 close to the inclined plate 365. The material is placed in the space between the two inclined plates 365. At this time, the side of the material is in contact with and squeezed by the two baffles 3613. Under the elastic force of the compression spring 3610, the baffle 3613 is forced to drive the middle column 3614 to slide inside the notch 3612, so that the material is located in the middle of the inclined plate 365 and the welding joints are aligned. The middle column 3614 is located inside the notch 3612, and the middle column 3614 passes through the inclined plate 365 through the notch 3612.
