The device includes a base and a forging table, as well as a forging mechanism, an adjustment mechanism, and a cleaning mechanism. The forging mechanism includes a vertical plate, a hammer, and a drive assembly. The adjustment mechanism includes an electric gripper, a tilting assembly, and a lifting assembly. The cleaning mechanism includes a cleaning brush, a traction assembly, a rotating assembly, and a reciprocating swing assembly. The cleaning brush is fixedly mounted on the reciprocating swing assembly. This high-strength heat-resistant magnesium alloy pipe fitting forging device can simultaneously clean the accumulated billet on the top of the forging table once before each tilting operation by the lifting assembly.

Description

Technical Field

[0001] This invention relates to the field of magnesium alloy forging product manufacturing, specifically to a forging device for high-strength heat-resistant magnesium alloy pipe fittings. Background Technology

[0002] Magnesium alloy forgings generally refer to magnesium alloy parts or components processed by forging. Forging is a metal forming process in which pressure is applied to shape the metal material in a mold to obtain the required shape and size. Magnesium alloy forgings are characterized by dense structure and excellent mechanical properties, and are suitable for various load-bearing structural components.

[0003] High-strength heat-resistant magnesium alloy pipe fittings refer to tubular parts made of high-strength heat-resistant magnesium alloy, which have excellent mechanical properties and high-temperature stability.

[0004] The existing magnesium alloy forging manufacturing equipment has the following shortcomings:

[0005] 1. During the forging process, the hammer repeatedly strikes the pipe blank, causing oxide scale to fall off the outer wall of the pipe. The oxide scale accumulates on the top of the forging table and gradually increases, making it easy for the oxide scale to be carried into the interior of the pipe blank by the hammer during subsequent forging processes, causing problems such as pits and cracks on the surface of the pipe.

[0006] 2. During the forging process, the pipe blank needs to be clamped by hand with iron clamps and the placement angle of the blank needs to be adjusted frequently. Due to the large weight of the blank, the work of adjusting the blank is time-consuming and laborious, which not only increases the labor intensity of workers, but also reduces the forging efficiency. Summary of the Invention

[0007] The purpose of this invention is to provide a forging device for high-strength heat-resistant magnesium alloy pipe fittings.

[0008] To achieve this objective, the present invention adopts the following technical solution:

[0017] Furthermore, the tilting assembly includes a second rotating shaft, a second motor, a first gear, a second gear, and a dual-axis cylinder. The second rotating shaft is rotatably mounted on the top of the lifting plate. The dual-axis cylinder is fixed to the outer wall of one end of the second rotating shaft via an L-shaped plate. The second gear is fixed to the outer wall of the other end of the second rotating shaft. The second motor is inserted into the outer wall of the lifting plate. The first gear is fixed to its output end and meshes with the second gear. The output end of the dual-axis cylinder is fixedly connected to the electric gripper.

[0018] Furthermore, the traction assembly includes a pull rope, a pull rod, a rack, a slide rail, a guide rod, a return spring, and two grooved wheels.

The outer wall of the pull rope is in contact with the outer edge of the two grooved wheels. The slide rail is fixed to the top of the base by two limiting plates. The rack slides on the outer wall of the slide rail. The end of the pull rope away from the pull rod passes through one of the limiting plates and is fixedly connected to one end of the rack. The guide rod is fixed to the other end of the rack and passes through the other limiting plate. The return spring is sleeved on the outer wall of the guide rod. An anti-detachment block is fixed to the end of the guide rod away from the limiting plate. The anti-detachment block and the limiting plate respectively abut against the two ends of the return spring.

[0019] Furthermore, the rotating assembly includes a third gear, a timing belt, and two timing pulleys. The top of the base is rotatably equipped with a drive shaft and a third rotating shaft, respectively. The two timing pulleys are fixed on the drive shaft and the third rotating shaft, respectively.

[0021] Furthermore, several anti-slip pads are fixedly installed on the outer wall of the electric gripper.

[0022] Furthermore, a U-shaped collection box is provided on the top of the base, and a limiting block is fixedly provided on the top of the base. The limiting block and the outer wall of the forging table are respectively attached to the outer walls of the two ends of the U-shaped collection box.

[0023] The beneficial effects of this invention are:

[0024] This invention designs a cleaning mechanism including a cleaning brush, a traction component, a rotating component, and a reciprocating swing component. By designing the traction component, it can drive the lifting component and the reciprocating swing component to operate synchronously, that is, drive the adjusting mechanism and the cleaning mechanism to operate synchronously. Specifically, before each time the tube blank is lifted by the lifting component to prepare for flipping, the cleaning brush simultaneously cleans the blank accumulated on the top of the forging table. This prevents the oxide scale that falls on the top of the forging table from being carried into the tube during the hammering process, causing problems such as pits and cracks on the surface of the tube. This is beneficial to improving the manufacturing quality and finished appearance of magnesium alloy forgings.

[0025] This invention, through the design of an adjustment mechanism, namely an electric gripper, a flipping component, and a lifting component, enables the electric gripper and the pipe blank held on it to move or flip rapidly via the lifting component and the flipping component. This eliminates the need for manual holding of heavy pipe blanks with iron clamps and frequent adjustment of the blank's placement angle, thus making the work of adjusting the blanks time-saving and labor-saving. This not only greatly reduces the labor intensity of workers but also improves forging efficiency.

[0026] This invention designs a U-shaped collection box, which is installed in a circular structure under the forging table. It can automatically collect and temporarily store the oxide scale swept down from the top of the forging table, making it convenient for recycling. This reduces environmental pollution and resource waste, and realizes the secondary utilization of resources in the manufacture of magnesium alloy forgings.

[0027] This invention designs a forging table, a forging mechanism, an adjustment mechanism, and a cleaning mechanism. Through the cooperation of these mechanisms, only one or two workers are needed to complete the forging of magnesium alloy pipe fittings. Compared with the previous method of requiring multiple workers for one device, this greatly saves labor costs and reduces the manufacturing cost of high-strength heat-resistant magnesium alloy pipe fittings, i.e., magnesium alloy forgings.

[0028] This invention improves the clamping effect and prevents the magnesium alloy pipe from falling off by designing several anti-slip pads on the clamping end of the electric gripper. The anti-slip pads are made of rubber and increase the friction between the clamping end of the electric gripper and the outer wall of the magnesium alloy pipe. Attached Figure Description

Detailed Implementation

[0040] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0041] The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual pictures. They should not be construed as limiting the invention. To better illustrate the embodiments of the invention, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual product dimensions.

[0042] Reference Figures 1 to 9 As shown, a forging device for high-strength heat-resistant magnesium alloy pipe fittings includes a base and a forging table 10, with the forging table 10 located on top of the base.

[0043] It also includes forging mechanisms, adjusting mechanisms, and cleaning mechanisms;

[0044] The forging mechanism is located on the top of the base. The forging mechanism includes a vertical plate, a hammer 11, and a drive assembly. The drive assembly is located on the outer wall of the vertical plate, and the hammer 11 is slidably located on the vertical plate.

[0045] The adjustment mechanism is located on the top of the base. The adjustment mechanism includes an electric gripper 12, a flipping assembly and a lifting assembly. The lifting assembly is located on the top of the base, the flipping assembly is located on the lifting assembly, and the electric gripper 12 is fixedly located on the flipping assembly.

[0046] The cleaning mechanism is located on the top of the base. The cleaning mechanism includes a cleaning brush 13, a traction component, a rotating component, and a reciprocating swing component. The rotating component is located on the top of the base, the traction component is located between the lifting component and the rotating component, the reciprocating swing component is located on the rotating component, and the cleaning brush 13 is fixedly located on the reciprocating swing component.

[0047] Reference Figures 1 to 9As shown, the drive assembly includes a first motor 14, a first rotating shaft 15, a turntable 16, and a first connecting rod 17. The first motor 14 is inserted into the top outer wall of the upright plate. The first rotating shaft 15 is rotatably mounted on the upright plate via a U-shaped plate. The output end of the first motor 14 is fixedly connected to one end of the first rotating shaft 15. The turntable 16 is fixedly mounted at the end of the first rotating shaft 15 away from the first motor 14. The first connecting rod 17 is hinged to the outer wall of the turntable 16. This device is equipped with a controller, and all drive devices within the device are electrically connected to the controller. When performing high-strength heat-resistant magnesium alloy pipe forging work, firstly... The pipe blank is placed vertically on top of the forging table 10, and the blank is kept directly below the hammer. The pipe blank is then clamped by the electric gripper 12 to ensure that the blank will not tilt or fall over when the hammer strikes it, thus improving the stability of forging. Then, the worker uses an iron clamp to place the punching head vertically on top of the initial hole in the center of the blank and supports the punch with the iron clamp. The first motor 14 is then started by the controller, so that its output end drives the first rotating shaft 15 to rotate. Since the first rotating shaft 15 is fixedly connected to the turntable 16, it drives the turntable 16 and the first connecting rod 17 on it to rotate.

[0048] Reference Figures 1 to 9 As shown, two support plates are fixedly installed on the outer wall of the upright plate. Each support plate has a guide block 18 fixedly installed on its outer wall. Each guide block 18 has a sliding column 19 slidably installed on its outer wall. A hammer 11 is fixedly installed between the two sliding columns 19. The top of the hammer 11 is hinged to the end of the first connecting rod 17 away from the turntable 16. When the turntable 16 drives the first upright to rotate, because the top of the hammer 11 is hinged to the end of the first connecting rod 17 away from the turntable 16, the outer wall of each support plate is fixedly connected to a guide block 18. Each guide block 18 is fixedly connected, and each sliding column 19 is slidably connected to a guide block 18. The hammer 11 is fixedly designed between two sliding columns 19, and then the first connecting rod 17 rotates to convert into a pushing force on the hammer, so that the hammer slides vertically back and forth to strike the punch, thereby causing the punch to descend vertically and drill into the interior of the initial hole to enlarge the initial hole. During this process, the worker gradually loosens the iron clamp to release the punch, thereby facilitating the punch to drill downward into the initial hole.

[0049] Reference Figures 1 to 9As shown, the lifting assembly includes a single-axis cylinder 20, a lifting plate 21, four sliders 22, and four guide rails 23. The four guide rails 23 are all fixedly mounted on the top of the base. Each slider 22 is slidably mounted on the outer wall of a guide rail 23. The lifting plate 21 is fixedly mounted between the four sliders 22. The single-axis cylinder 20 is fixedly mounted on the top of the base, and its output end is fixedly connected to the bottom of the lifting plate 21. When half of the initial hole of the billet is enlarged, the single-axis cylinder 20 is activated by the controller, thereby causing its output end to extend upward. Since the lifting plate 21 is slidably connected to the four guide rails 23 through the four sliders 22, and the four guide rails 23 are all fixedly connected to the base, the lifting plate 21 and the electric gripper 12 on it rise, thereby driving the clamped magnesium alloy tube billet to rise a certain distance.

[0050] Reference Figures 1 to 9 As shown, the tilting assembly includes a second rotating shaft 24, a second motor 25, a first gear 26, a second gear 27, and a dual-shaft cylinder 28. The second rotating shaft 24 is rotatably mounted on the top of the lifting plate 21. The dual-shaft cylinder 28 is fixed to the outer wall of one end of the second rotating shaft 24 via an L-shaped plate. The second gear 27 is fixed to the outer wall of the other end of the second rotating shaft 24. The second motor 25 is inserted into the outer wall of the lifting plate 21. The first gear 26 is fixed to its output end and meshes with the second gear 27. The output end of the dual-shaft cylinder 28 is fixedly connected to the electric gripper 12. When the magnesium alloy tube blank rises a certain distance, the controller starts the second motor 25, causing its output end to drive the first gear 26 to rotate. Since the second gear 27 and the L-shaped plate are respectively connected to the second... The two ends of the rotating shaft 24 are fixedly connected, the first gear 26 and the second gear 27 are meshed, the dual-shaft cylinder 28 is fixedly connected to the L-shaped plate, and the electric gripper 12 is fixedly connected to its output end, thereby driving the clamped pipe blank to rotate 180 degrees. Then, other punches are placed on the top of the end of the initial hole that has not been enlarged. Then, the controller starts the first motor 14, which drives the hammer to slide vertically back and forth through the drive assembly. The hammer strikes the punch placed on the top of the end of the initial hole that has not been enlarged, thereby enlarging the other half of the initial hole, thus enlarging the entire initial hole. This shapes the pipe blank into the pipe shape, realizing the forging of high-strength heat-resistant magnesium alloy pipes. It eliminates the need for frequent manual turning of the pipe blank, saving time and labor, and thus improving the manufacturing efficiency of magnesium alloy forging products.

[0051] Reference Figures 1 to 9As shown, the traction assembly includes a pull rope 29, a pull rod 30, a rack 31, a slide rail 32, a guide rod 33, a return spring 34, and two grooved wheels 35. The pull rod 30 is fixed to the outer wall of the lifting plate 21, and the pull rope 29 is fixed to the bottom of the pull rod 30. Both grooved wheels 35 are rotatably mounted on the top of the base, with the outer wall of the pull rope 29 fitting against the outer edges of the two grooved wheels 35. The slide rail 32 is fixed to the top of the base via two limiting plates. The rack 31 slides on the outer wall of the slide rail 32. The end of the pull rope 29 away from the pull rod 30 passes through one of the limiting plates and is fixedly connected to one end of the rack 31. The guide rod 33 is fixed to the other end of the rack 31 and passes through the other limiting plate. The return spring 34 is sleeved on the outer wall of the guide rod 33. An anti-detachment block 36 is fixedly mounted on the end of the guide rod 33 away from the limiting plate. The anti-detachment block 36 and... The limiting plates abut against both ends of the return spring 34. As the lifting plate 21 drives the pipe blank to rise, the lifting plate 21 is fixedly connected to the pull rope 29 via the pull rod 30. The end of the pull rope 29 away from the pull rod 30 is fixedly connected to one end of the rack 31. Under the limiting action of the two grooved wheels 35, the rack 31 is pulled by the pull rope 29 and slides towards the end closer to the forging table 10 inside the slide rail 32. Since the other end of the rack 31 is slidably connected to one of the limiting plates via the guide rod 33, the return spring 34 is sleeved with the guide rod 33. The end of the guide rod 33 away from the limiting plate is fixedly connected to the anti-detachment block 36. The anti-detachment block 36 and the limiting plate abut against both ends of the return spring 34. Thus, the return spring 34 is pushed from the initial state to the taut state by the sliding of the anti-detachment block 36 towards the end closer to the forging table 10.

[0052] Reference Figures 1 to 9 As shown, the rotating assembly includes a third gear 37, a synchronous belt 38, and two synchronous pulleys 39. The top of the base is rotatably equipped with a drive shaft 40 and a third rotating shaft 41. The two synchronous pulleys 39 are fixedly mounted on the drive shaft 40 and the third rotating shaft 41, respectively. The third gear 37 is fixedly mounted on the drive shaft 40 and meshes with the rack 31. The synchronous belt 38 is sleeved between the two synchronous pulleys 39. When the rack 31 is pulled by the rope 29 and slides towards the end of the slide rail 32 closer to the forging table 10, the third gear 37 meshes with the rack 31, and the two synchronous pulleys 39 are fixedly connected to the drive shaft 40 and the third rotating shaft 41, respectively. The third gear 37 is fixedly connected to the drive shaft 40, and the two synchronous pulleys 39 are sleeved through the synchronous belt 38, thereby driving the third rotating shaft 41 to rotate.

[0053] Reference Figures 1 to 9As shown, the reciprocating oscillating assembly includes a swing arm 42, a second connecting rod 43, an insert rod 44, and a transmission rod 45. The swing arm 42 is fixedly mounted on the top of the third rotating shaft 41. The transmission rod 45 is rotatably mounted on the top of the base via a fourth rotating shaft 46. The second connecting rod 43 is hinged to the end of the swing arm 42 away from the third rotating shaft 41. The insert rod 44 is fixedly mounted on the top end of the second connecting rod 43 away from the swing arm 42. One end of the transmission rod 45 is fixedly connected to the cleaning brush 13, and the end of the transmission rod 45 away from the cleaning brush 13 has an opening. The device has a clearance groove, and the insertion rod 44 is inserted into the clearance groove. The top of the insertion rod 44 is fixedly equipped with an anti-detachment post. When the third rotating shaft 41 rotates, since one end of the swing rod 42 is fixedly connected to the third rotating shaft 41, the transmission rod 45 is rotatably connected to the base through the fourth rotating shaft 46. One end of the transmission rod 45 is fixedly connected to the cleaning brush 13, and the other end of the transmission rod 45 is designed with a clearance groove. One end of the second connecting rod 43 is hinged to the end of the swing rod 42 away from the third rotating shaft 41, and the insertion rod 44 is fixedly connected to the other end of the second connecting rod 43. The insertion rod 44 is inserted into the clearance groove, and when the swing rod 42 rotates, it drives the second connecting rod 43 and the insertion rod 44 to rotate. When the insertion rod 44 rotates inside the clearance groove, the contact motion between it and the clearance groove is converted into the rotational motion of the cleaning brush 13 through the transmission rod 45. As the lifting plate 21 lifts the pipe blank and separates it from the forging table 10, it simultaneously drives the cleaning brush 13 to rotate once. The oxide scale that falls from the outer wall of the pipe blank to the top of the forging table 10 during the hammering is swept into the U-shaped collection box 48 for collection. On the one hand, it can ensure the cleanliness of the top of the forging table 10 and prevent the oxide scale that falls to the top of the forging table 10 from being carried into the pipe during the hammering process, causing problems such as pits and cracks on the surface of the pipe. This is conducive to improving the manufacturing quality and finished appearance of magnesium alloy forging products. On the other hand, the collected oxide scale can be recycled, thereby reducing environmental pollution and resource waste, and realizing the secondary utilization of resources in the manufacturing of magnesium alloy forging products.

[0054] Reference Figures 1 to 9 As shown, several anti-slip pads 47 are fixed on the outer wall of the electric gripper 12. The anti-slip pads 47 are made of rubber and can increase the friction between the gripping end of the electric gripper 12 and the outer wall of the magnesium alloy pipe, thereby improving the clamping effect and preventing the pipe from falling off during the clamping process.

[0055] Reference Figures 1 to 9 As shown, a U-shaped collection box 48 is provided on the top of the base, and a limiting block 49 is fixedly provided on the top of the base. The limiting block 49 and the outer wall of the forging table 10 are respectively attached to the outer walls of both ends of the U-shaped collection box 48. The limiting block 49 and the forging table 10 cooperate to fix the U-shaped collection box 48 in place, which improves the installation stability of the U-shaped collection box 48 and ensures that the oxide scale swept down from the top of the forging table 10 will not move the U-shaped collection box 48, thereby ensuring the collection effect.

[0056] The working principle of this invention: This device is equipped with a controller, and all driving devices in the device are electrically connected to the controller. When forging high-strength heat-resistant magnesium alloy pipe fittings, the pipe fitting blank is first placed vertically on the top of the forging table 10, and the blank is kept directly below the hammer. Then, the pipe fitting blank is clamped by the electric gripper 12 to ensure that the blank will not tilt or even fall over when the hammer strikes it, thus improving the stability of forging. Then, the worker uses an iron clamp to place the punching head vertically on the top of the initial hole in the center of the blank and uses the iron clamp to support the punch. Then, the controller starts the first motor 14, so that its output end drives the first rotating shaft 15 to rotate. Since the first rotating shaft 15 is fixedly connected to the turntable 16, it drives the turntable 16 and the first connecting rod 17 on it to rotate.

[0057] When the turntable 16 drives the first upright to rotate, the top of the hammer 11 is hinged to the end of the first connecting rod 17 away from the turntable 16. Each support plate is fixedly connected to a guide block 18 on its outer wall, and each sliding column 19 is slidably connected to a guide block 18. The hammer 11 is fixedly designed between two sliding columns 19, and then the rotation of the first connecting rod 17 is converted into a pushing force on the hammer, so that the hammer slides vertically back and forth to strike the punch, thereby causing the punch to descend vertically and drill into the interior of the initial hole to enlarge the initial hole. During this process, the worker gradually loosens the iron clamp to release the punch, thus facilitating the punch to drill downward into the initial hole.

[0058] After half of the initial hole of the billet is enlarged, the single-axis cylinder 20 is activated by the controller, so that its output end extends upward. Since the lifting plate 21 is slidably connected to the four guide rails 23 through the four sliders 22, and the four guide rails 23 are fixedly connected to the base, the lifting plate 21 and the electric gripper 12 on it rise, thereby driving the magnesium alloy tube billet being held to rise a certain distance.

[0059] After the magnesium alloy tube blank rises a certain distance, the controller starts the second motor 25, which drives the first gear 26 to rotate. Since the second gear 27 and the L-shaped plate are fixedly connected to the two ends of the second rotating shaft 24, the first gear 26 and the second gear 27 are meshed. The dual-shaft cylinder 28 is fixedly connected to the L-shaped plate, and the electric gripper 12 is fixedly connected to its output end, thereby driving the clamped tube blank to rotate 180 degrees. Then, other punches are placed on the top of the end of the initial hole that has not been enlarged. Then, the controller starts the first motor 14, which drives the hammer to slide vertically back and forth through the drive assembly. The hammer strikes the punches placed on the top of the end of the initial hole that has not been enlarged, thereby enlarging the other half of the initial hole, thus enlarging the entire initial hole. This shapes the tube blank into the tube blank, achieving the forging of high-strength heat-resistant magnesium alloy tubes. There is no need to frequently turn the tube blank manually, saving time and labor, and thus improving the manufacturing efficiency of magnesium alloy forging products.

[0060] As the lifting plate 21 lifts the pipe blank, the lifting plate 21 is fixedly connected to the pull rope 29 via the pull rod 30. The end of the pull rope 29 away from the pull rod 30 is fixedly connected to one end of the rack 31. Under the limiting action of the two grooved wheels 35, the rack 31 is pulled by the pull rope 29 and slides towards the end closer to the forging table 10 inside the slide rail 32. The other end of the rack 31 is slidably connected to one of the limiting plates via the guide rod 33. The return spring 34 is sleeved with the guide rod 33. The end of the guide rod 33 away from the limiting plate is fixedly connected to the anti-detachment block 36. The anti-detachment block 36 and the limiting plate respectively abut against the two ends of the return spring 34. Thus, the return spring 34 is pushed from the initial state to the taut state by the sliding of the anti-detachment block 36 towards the end closer to the forging table 10.

[0061] When the rack 31 is pulled by the rope 29 and slides towards the end of the slide rail 32, the third gear 37 meshes with the rack 31, the two synchronous pulleys 39 are fixedly connected to the drive shaft 40 and the third rotating shaft 41 respectively, the third gear 37 is fixedly connected to the drive shaft 40, and the two synchronous pulleys 39 are connected by the synchronous belt 38, thereby driving the third rotating shaft 41 to rotate.

[0062] When the third rotating shaft 41 rotates, one end of the swing arm 42 is fixedly connected to the third rotating shaft 41, and the transmission rod 45 is rotatably connected to the base via the fourth rotating shaft 46. One end of the transmission rod 45 is fixedly connected to the cleaning brush 13, and the other end of the transmission rod 45 is designed with a clearance groove. One end of the second connecting rod 43 is hinged to the end of the swing arm 42 away from the third rotating shaft 41, and the insertion rod 44 is fixedly connected to the other end of the second connecting rod 43, and the insertion rod 44 is inserted into the clearance groove. Thus, when the swing arm 42 rotates, it drives the second connecting rod 43 and the insertion rod 44 to rotate, so that the contact motion between the insertion rod 44 and the clearance groove when rotating inside the clearance groove is converted into a rotational motion on the cleaning brush 13 through the transmission rod 45, thereby making the lifting plate 2 1. While the pipe blank is lifted and detached from the forging table 10, the cleaning brush 13 rotates once to clean the oxide scale that falls from the outer wall of the pipe blank to the top of the forging table 10 during the hammering process. The scale is then collected inside the U-shaped collection box 48. On the one hand, this ensures the cleanliness of the top of the forging table 10 and prevents the oxide scale that falls to the top of the forging table 10 from being carried into the pipe during the hammering process, which could cause pits, cracks, and other problems on the surface of the pipe. This is beneficial to improving the manufacturing quality and appearance of magnesium alloy forgings. On the other hand, the collected oxide scale can be recycled, which can reduce environmental pollution and resource waste, and realize the secondary utilization of resources in the manufacturing of magnesium alloy forgings.

[0063] The anti-slip pad 47 is made of rubber, which increases the friction between the clamping end of the electric gripper 12 and the outer wall of the magnesium alloy pipe, thereby improving the clamping effect and preventing the pipe from falling off during the clamping process.

[0064] The limiting block 49 works in conjunction with the forging table 10 to fix the U-shaped collection box 48 in place, which improves the installation stability of the U-shaped collection box 48 and ensures that the oxide scale swept down from the top of the forging table 10 will not move the U-shaped collection box 48, thereby ensuring the collection effect.
