Description

Technical Field

[0001] The present invention relates to the field of manufacturing magnesium alloy forging products, and particularly relates to a forging device for high-strength heat-resistant magnesium alloy pipe fittings. Background Art

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

[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 structure of the existing magnesium alloy forging product manufacturing device has the following deficiencies: 1. During the forging process, the knocking hammer reciprocally strikes the pipe fitting blank, and oxide scales will fall off from the outer wall of the pipe fitting. The fallen oxide scales accumulate on the top of the forging table and gradually increase, which easily causes the oxide scales to be brought into the interior of the pipe fitting blank by the knocking hammer during the subsequent forging process, resulting in problems such as pits and cracks on the surface of the pipe fitting.

[0005] 2. During the forging process, it is necessary to manually hold an iron clamp to clamp the pipe fitting blank and frequently adjust the placement angle of the blank. 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 the workers but also reduces the forging efficiency.

[0017] Advantages of the present invention: 1.

That is, before each time the lifting assembly drives the pipe fitting blank to rise for flipping, the cleaning brush cleans the blank accumulated on the top of the forging table once, preventing the scale falling on the top of the forging table from being brought into the inside of the pipe fitting during the knocking process of the knocking hammer, which may cause problems such as pits and cracks on the surface of the pipe fitting, and thus is beneficial to improving the quality and finished product appearance of the magnesium alloy forging product.

[0018] 2. By designing the adjusting mechanism, namely the electric gripper, the flipping assembly, and the lifting assembly, it can drive the electric gripper and the pipe fitting blank clamped thereon to move or flip quickly through the lifting assembly and the flipping assembly, without manually holding an iron clamp to clamp the relatively heavy pipe fitting blank and frequently adjusting the placement angle of the blank. Thus, the work of adjusting the blank is time - saving and labor - saving, not only greatly reducing the labor intensity of workers, but also improving the forging efficiency.

[0019] 3. By designing the U - shaped collection box, which is installed in a surrounding structure under the forging table, it can automatically receive and temporarily store the scale swept from the top of the forging table, facilitating recycling, and thus can reduce environmental pollution and resource waste, realizing the secondary utilization of resources in the manufacture of magnesium alloy forging products.

[0020] 4. The present invention designs a forging table, a forging mechanism, an adjusting mechanism and a cleaning mechanism. Through the cooperation of the above mechanisms, only one or two workers are required for one device to achieve the forging work of magnesium alloy pipe fittings. Compared with the previous situation where multiple workers were required for one device, the labor cost is greatly saved, and thus the manufacturing cost of high-strength heat-resistant magnesium alloy pipe fittings, that is, magnesium alloy forging products, is reduced.

[0021] 5. The present invention designs a number of anti-slip pads on the clamping end of the electric gripper. The anti-slip pads are made of rubber material, which can increase the friction between the clamping end of the electric gripper and the outer wall of the magnesium alloy pipe fitting, thereby improving the clamping effect and preventing the pipe fitting from falling during the clamping process of the magnesium alloy pipe fitting.

[0026] Referring to 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, and the forging table 10 is arranged on the top of the base; It further includes a forging mechanism, an adjusting mechanism and a cleaning mechanism; The forging mechanism is arranged on the top of the base. The forging mechanism includes a vertical plate, a hammer 11 and a driving component. The driving component is arranged on the outer wall of the vertical plate, and the hammer 11 is slidably arranged on the vertical plate; The adjusting mechanism is arranged on the top of the base. The adjusting mechanism includes an electric gripper 12, a flipping component and a lifting component. The lifting component is arranged on the top of the base, the flipping component is arranged on the lifting component, and the electric gripper 12 is fixedly arranged on the flipping component; The cleaning mechanism is arranged 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 arranged on the top of the base, the traction component is arranged between the lifting component and the rotating component, the reciprocating swing component is arranged on the rotating component, and the cleaning brush 13 is fixedly arranged on the reciprocating swing component.

[0027] Referring to Figures 1 to 9As shown, the driving 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 on the outer wall of the top of the vertical plate. The first rotating shaft 15 is rotatably arranged on the vertical plate through 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 arranged at the end of the first rotating shaft 15 away from the first motor 14. The first connecting rod 17 is hinged on the outer wall of the turntable 16. This device is equipped with a controller, and each driving device in the device is electrically connected to the controller. When forging high-strength heat-resistant magnesium alloy pipe fittings, first place the pipe fitting blank vertically on the top of the forging table 10 and keep the blank directly below the knocking hammer. Then clamp the pipe fitting blank with the electric gripper 12 to ensure that the blank will not skew or even fall down when the knocking hammer strikes the blank, improving the stability of forging. Then the worker vertically places the punch for punching on the top of the initial hole in the center of the blank with an iron clamp and holds the punch with the iron clamp. Then start the first motor 14 through 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, the turntable 16 and the first connecting rod 17 thereon are driven to rotate.

[0028] Refer to Figures 1 to 9 As shown, two support plates are fixedly arranged on the outer wall of the vertical plate. A guide block 18 is fixedly arranged on the outer wall of each support plate. A sliding column 19 is slidably arranged on the outer wall of each guide block 18. The knocking hammer 11 is fixedly arranged between the two sliding columns 19. The top of the knocking 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 vertical rod to rotate, since the top of the knocking 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 sliding column 19 is slidably connected to a guide block 18, and the knocking hammer 11 is fixedly designed between the two sliding columns 19. Furthermore, the rotation of the first connecting rod 17 is converted into a pushing force on the knocking hammer, enabling the knocking hammer to reciprocate vertically, realizing the knocking on the punch, so that the punch vertically descends into the interior of the initial hole to expand the initial hole. During this process, the worker gradually releases the iron clamp to release the punch, facilitating the downward drilling of the punch into the initial hole.

[0029] Refer to Figures 1 to 9As shown in the figure, 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 arranged on the top of the base. Each slider 22 is slidably arranged on the outer wall of a guide rail 23. The lifting plate 21 is fixedly arranged between the four sliders 22. The single-axis cylinder 20 is fixedly arranged on the top of the base, and its output end is fixedly connected to the bottom of the lifting plate 21. 3 When half of the initial hole of the blank is enlarged, the single-axis cylinder 20 is started through 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 all fixedly connected to the base, the lifting plate 21 and the electric gripper 12 thereon rise, thereby driving the clamped magnesium alloy pipe blank to rise a certain distance.

[0030] Refer to Figures 1 to 9 As shown in the figure, the flipping assembly includes a second rotating shaft 24, a second motor 25, a first gear 26, a second gear 27 and a double-axis cylinder 28. The second rotating shaft 24 is rotatably arranged on the top of the lifting plate 21. The double-axis cylinder 28 is fixedly arranged on the outer wall of one end of the second rotating shaft 24 through an L-shaped plate. The second gear 27 is fixedly arranged on 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, and the first gear 26 is fixedly arranged on its output end. The first gear 26 is meshed with the second gear 27. The output end of the double-axis cylinder 28 is fixedly connected to the electric gripper 12. 4 When the magnesium alloy pipe blank rises a certain distance, the second motor 25 is started through the controller, so that its output end drives the first gear 26 to rotate. Since the second gear 27 and the L-shaped plate are respectively fixedly connected to the two ends of the second rotating shaft 24, the first gear 26 and the second gear 27 are meshed, the double-axis 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 where the initial hole has not been enlarged. Then, the first motor 14 is started through the controller, so that the driving assembly drives the percussion hammer to reciprocate vertically. The punch placed on the top of the end where the initial hole has not been enlarged is reciprocally struck by the percussion hammer to realize the enlargement of the other half of the initial hole, and then the entire initial hole is enlarged, forging the pipe blank into the shape of a pipe, realizing the forging of high-strength heat-resistant magnesium alloy pipes. There is no need to manually flip the pipe blank frequently, which saves time and effort, and thus improves the manufacturing efficiency of magnesium alloy forging products.

[0031] Refer to Figures 1 to 9As shown in the figure, 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 sheave wheels 35. The pull rod 30 is fixedly arranged on the outer wall of the lifting plate 21. The pull rope 29 is fixedly arranged at the bottom of the pull rod 30. Both of the two sheave wheels 35 are rotatably arranged on the top of the base. The outer wall of the pull rope 29 is in contact with the outer edges of the two sheave wheels 35. The slide rail 32 is fixedly arranged on the top of the base through two limit plates. The rack 31 is slidably arranged on the outer wall of the slide rail 32. One end of the pull rope 29 away from the pull rod 30 passes through one of the limit plates and is fixedly connected to one end of the rack 31. The guide rod 33 is fixedly arranged at the other end of the rack 31. The guide rod 33 passes through the other limit plate. The return spring 34 is sleeved on the outer wall of the guide rod 33. An anti - detachment block 36 is fixedly arranged at the end of the guide rod 33 away from the limit plate. The anti - detachment block 36 and the limit plate are respectively in contact with the two ends of the return spring 34. While the lifting plate 21 drives the pipe blank to rise, since the lifting plate 21 is fixedly connected to the pull rope 29 through the pull rod 30, and one 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 sheave wheels 35, the rack 31 is pulled by the pull rope 29 and slides towards the end close 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 limit plates through the guide rod 33, the return spring 34 is sleeved on the guide rod 33, the end of the guide rod 33 away from the limit plate is fixedly connected to the anti - detachment block 36, and the anti - detachment block 36 and the limit plate are respectively in contact with the two ends of the return spring 34, thus the anti - detachment block 36 slides towards the end close to the forging table 10 and drives the return spring 34 to be compressed from the initial state to a taut state.

[0032] Refer to Figures 1 to 9 As shown in the figure, the rotation assembly includes a third gear 37, a synchronous belt 38, and two synchronous wheels 39. A transmission shaft 40 and a third rotating shaft 41 are respectively rotatably arranged on the top of the base. The two synchronous wheels 39 are respectively fixedly arranged on the transmission shaft 40 and the third rotating shaft 41. The third gear 37 is fixedly arranged on the transmission shaft 40. The third gear 37 is meshed with the rack 31. The synchronous belt 38 is sleeved between the two synchronous wheels 39. When the rack 31 is pulled by the pull rope 29 and slides towards the end close to the forging table 10 inside the slide rail 32, since the third gear 37 is meshed with the rack 31, the two synchronous wheels 39 are respectively fixedly connected to the transmission shaft 40 and the third rotating shaft 41, the third gear 37 is fixedly connected to the transmission shaft 40, and the two synchronous wheels 39 are sleeved through the synchronous belt 38, thus driving the third rotating shaft 41 to rotate.

[0033] Refer to Figures 1 to 9As shown in the figure, the reciprocating swing assembly includes a swing rod 42, a second connecting rod 43, a plug rod 44 and a transmission rod 45. The swing rod 42 is fixedly arranged at the top of the third rotating shaft 41. The transmission rod 45 is rotatably arranged at the top of the base through a fourth rotating shaft 46. The second connecting rod 43 is hinged at one end of the swing rod 42 away from the third rotating shaft 41. The plug rod 44 is fixedly arranged at the top end of the second connecting rod 43 away from the swing rod 42. One end of the transmission rod 45 is fixedly connected to the cleaning brush 13. An avoidance groove is formed at one end of the transmission rod 45 away from the cleaning brush 13. The plug rod 44 is inserted into the avoidance groove. A anti - detachment column is fixedly arranged at the top of the plug rod 44. 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, an avoidance groove is designed at the other end of the transmission rod 45, 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, the plug rod 44 is fixedly connected to the other end of the second connecting rod 43, and the plug rod 44 is inserted into the avoidance groove. Thus, when the swing rod 42 rotates, it drives the second connecting rod 43 and the plug rod 44 to rotate. When the plug rod 44 rotates inside the avoidance groove, the contact movement generated with the avoidance groove is converted into a rotational movement of the cleaning brush 13 through the transmission rod 45. Thus, while the lifting plate 21 drives the pipe fitting blank to rise and separate from the forging table 10, the synchronous belt 38 drives the cleaning brush 13 to rotate once, cleaning the scale that falls onto the top of the forging table 10 from the outer wall of the pipe fitting blank during the knocking of the knocking hammer 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, prevent the scale falling on the top of the forging table 10 from being brought into the pipe fitting during the knocking of the knocking hammer, resulting in problems such as pits and cracks on the surface of the pipe fitting, and thus is conducive to improving the quality and finished product appearance of the magnesium alloy forging products. On the other hand, the collected scale can be recycled, thereby reducing environmental pollution and resource waste, and realizing the secondary utilization of the resources in the manufacture of magnesium alloy forging products.

[0034] Refer to Figures 1 to 9 As shown in the figure, a number of anti - slip pads 47 are fixedly arranged on the outer wall of the electric gripper 12. The anti - slip pads 47 are made of rubber material, which can increase the friction between the clamping end of the electric gripper 12 and the outer wall of the magnesium alloy pipe fitting, thus improving the clamping effect and preventing the pipe fitting from falling during the clamping process of the magnesium alloy pipe fitting.

[0035] Refer to Figures 1 to 9 As shown in the figure, a U - shaped collection box 48 is arranged on the top of the base. A limiting block 49 is fixedly arranged on the top of the base. The outer walls of the limiting block 49 and the forging table 10 are respectively attached to the two outer walls 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, improving the installation stability of the U - shaped collection box 48, so that the scale swept from the top of the forging table 10 will not move the U - shaped collection box 48, thereby ensuring the collection effect.

[0036] Working principle of the present invention: This device is equipped with a controller, and each driving device in the device is electrically connected to the controller. When forging high-strength heat-resistant magnesium alloy pipe fittings, first place the pipe fitting blank vertically on the top of the forging table 10 and keep the blank directly below the knocking hammer. Then clamp the pipe fitting blank with the electric gripper 12 to ensure that the blank will not skew or even fall down when the knocking hammer strikes the blank, improving the stability of forging. Then the worker vertically places the punch for punching on the top of the initial hole in the center of the blank with an iron clamp and holds the punch with the iron clamp. Then start the first motor 14 through 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, the turntable 16 and the first connecting rod 17 thereon are driven to rotate.

[0037] When the turntable 16 drives the first vertical rod to rotate, since the top of the knocking hammer 11 is hinged to the end of the first connecting rod 17 far from the turntable 16, a guide block 18 is fixedly connected to the outer wall of each support plate, each sliding column 19 is slidably connected to a guide block 18, and the knocking hammer 11 is fixedly designed between the two sliding columns 19. Then the rotation of the first connecting rod 17 is converted into a pushing force on the knocking hammer, so that the knocking hammer reciprocates vertically, realizing the knocking on the punch, so that the punch vertically descends into the initial hole, expanding the initial hole. During this process, the worker gradually releases the iron clamp to release the punch, facilitating the downward drilling of the punch into the initial hole.

[0038] When half of the initial hole of the blank is expanded, start the single-axis cylinder 20 through 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 thereon rise, thereby driving the clamped magnesium alloy pipe fitting blank to rise a certain distance.

[0039] When the magnesium alloy pipe fitting blank rises a certain distance, start the second motor 25 through the controller, so that its output end 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 respectively, the first gear 26 and the second gear 27 are meshed and connected, the double-axis cylinder 28 is fixedly connected to the L-shaped plate, and the electric gripper 12 is fixedly connected to its output end. Then the clamped pipe fitting blank is driven to rotate 180 degrees. Then place other punches on the top of the end where the initial hole has not been expanded. Then start the first motor 14 through the controller, so that the knocking hammer is driven to reciprocate vertically through the driving assembly. By knocking the punch placed on the top of the end where the initial hole has not been expanded with the knocking hammer, the other half of the initial hole is expanded, and then the entire initial hole is expanded, forging the pipe fitting blank into the shape of a pipe fitting, realizing the forging of high-strength heat-resistant magnesium alloy pipe fittings, without the need for manual frequent turning of the pipe fitting blank, saving time and effort, and thus improving the manufacturing efficiency of magnesium alloy forging products.

[0040] While the lifting plate 21 drives the pipe fitting blank to rise, since the lifting plate 21 is fixedly connected to the pulling rope 29 through the pull rod 30, and one end of the pulling rope 29 far from the pull rod 30 is fixedly connected to one end of the rack 31. Under the limiting action of the two sheave wheels 35, the rack 31 is subjected to the pulling force of the pulling rope 29 and slides towards the end close 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 through the guide rod 33, the return spring 34 is sleeved on the guide rod 33, and one end of the guide rod 33 far 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 squeezed from the initial state to a taut state by the sliding of the anti - detachment block 36 towards the end close to the forging table 10.

[0041] When the rack 31 is subjected to the pulling force of the pulling rope 29 and slides towards the end close to the forging table 10 inside the slide rail 32, since the third gear 37 is meshed with the rack 31, the two synchronous pulleys 39 are respectively fixedly connected to the transmission shaft 40 and the third rotating shaft 41, the third gear 37 is fixedly connected to the transmission shaft 40, and the two synchronous pulleys 39 are sleeved by the synchronous belt 38. Thus, the third rotating shaft 41 is driven to rotate.

[0042] 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, the other end of the transmission rod 45 is designed with an avoidance groove, one end of the second connecting rod 43 is hinged to the end of the swing rod 42 far from the third rotating shaft 41, the inserting rod 44 is fixedly connected to the other end of the second connecting rod 43, and the inserting rod 44 is inserted into the avoidance groove. Thus, when the swing rod 42 rotates, it drives the second connecting rod 43 and the inserting rod 44 to rotate. When the inserting rod 44 rotates inside the avoidance groove, the abutting movement generated with the avoidance groove is converted into the rotational movement of the cleaning brush 13 through the transmission rod 45. Thus, while the lifting plate 21 drives the pipe fitting blank to rise and separate from the forging table 10, the synchronous belt 38 drives the cleaning brush 13 to rotate once, and the scale falling on the top of the forging table 10 from the outer wall of the pipe fitting blank during the knocking of the knocking hammer 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, prevent the scale falling on the top of the forging table 10 from being brought into the pipe fitting during the knocking of the knocking hammer, which may cause problems such as pits and cracks on the surface of the pipe fitting, and thus is beneficial to improving the quality and finished product appearance of the magnesium alloy forging products. On the other hand, the collected scale can be recycled, which can reduce environmental pollution and waste of resources, and realize the secondary utilization of the resources in the manufacture of magnesium alloy forging products.

[0043] The anti-slip mat 47 is made of rubber material, which can increase the friction force between the clamping end of the electric gripper 12 and the outer wall of the magnesium alloy pipe fitting, thereby improving the clamping effect and preventing the pipe fitting from falling during the clamping of the magnesium alloy pipe fitting.

[0044] The limit block 49 and the forging table 10 cooperate to fix the U-shaped collection box 48 in place, improving the installation stability of the U-shaped collection box 48, so that the scale swept from the top of the forging table 10 does not move the U-shaped collection box 48, thereby ensuring the collection effect.
