Description

Technical Field

[0001] The invention relates to the technical field of aluminum alloy stamping, in particular to a stamping die for an aluminum alloy skylight mounting bracket. Background Art

[0002] Aluminum alloy skylight mounting bracket refers to the structural component used to install and fix the aluminum alloy skylight. The skylight is a window installed on the roof or wall, usually used to increase the entry of natural light and improve indoor ventilation. However, the aluminum alloy skylight mounting bracket needs to be stamped and bent;

[0003] However, when stamping the aluminum alloy skylight mounting bracket, the staff needs to hold the aluminum alloy by hand and place it under the stamping machine, and then perform stamping and bending. Although it can be bent and stamped, there will be a rebound phenomenon after the aluminum alloy is stamped and bent. Because in a single large-angle bending process, the material will be subjected to huge local pressure in the bending area. This high stress state will cause the material to rebound after bending. If rebound occurs, it will not only affect the assembly accuracy of the product but also affect the subsequent use performance. In addition, when stamping and bending the aluminum alloy, the aluminum alloy will warp in the unbent part, which will affect the deviation of the aluminum alloy stamping and bending or fail to complete the stamping and bending.

[0004] In addition, when stamping aluminum alloy, heat will be generated at the stamped part. During the bending process of aluminum alloy, the metal material is subjected to huge external force, which causes the atoms or molecules inside the material to shift. This displacement consumes energy, which is released in the form of heat and causes the stamped part of the aluminum alloy to generate heat, making it easy to separate from the stamping die.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. In the stamping die for the aluminum alloy sunroof mounting bracket, the stamping structure moves toward the bottom of the shell, and drives the bending structures to move close to each other to clamp the aluminum alloy, thereby achieving clamping and limiting the aluminum alloy before bending to prevent the aluminum alloy from detaching during bending. Then the stamping structure continues to move and bend the aluminum alloy clamped by the bending structure, and then drives the adsorption structure to adsorb the aluminum alloy initially clamped by the bending structure, thereby achieving initial bending of the aluminum alloy clamped by the bending structure. By gradually increasing the stress in the bending area of ​​the aluminum alloy, the stress each time will be relatively small, thereby reducing the concentration of local stress of the aluminum alloy and reducing the possibility of springback.

[0019] 2.

[0031] The following will be combined with the accompanying drawings in the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] However, when stamping the aluminum alloy skylight mounting bracket, the staff needs to hold the aluminum alloy by hand and place it under the stamping machine, and then perform stamping and bending. Although it can be bent and stamped, there will be a rebound phenomenon after the aluminum alloy is stamped and bent. Because in a single large-angle bending process, the material will be subjected to huge local pressure in the bending area. This high stress state will cause the material to rebound after bending. If rebound occurs, it will not only affect the assembly accuracy of the product but also affect the subsequent use performance. In addition, when stamping and bending the aluminum alloy, the aluminum alloy will warp in the unbent part, which will affect the deviation of the aluminum alloy stamping and bending or fail to complete the stamping and bending.

[0033] In addition, when stamping aluminum alloy, the stamped part will generate heat. During the bending process of aluminum alloy, the metal material is subjected to huge external force, which causes the atoms or molecules inside the material to move. This displacement consumes energy, which is released in the form of heat, and causes the stamped part of the aluminum alloy to generate heat, which is easy to separate from the stamping die. For the embodiments of the present invention, please refer to Figures 1 to 9 A stamping die for an aluminum alloy sunroof mounting bracket comprises a housing 1, a cylinder 2 is arranged on the top of the housing 1, a stamping structure 300 for stamping aluminum alloy is arranged at the bottom of the cylinder 2 penetrating the housing 1, a bending structure 400 for clamping the aluminum alloy is arranged at the bottom of the stamping structure 300, and an adsorption structure 500 for adsorbing the aluminum alloy is arranged at the bottom of the bending structure 400;

[0034] During the initial bending, the stamping structure 300 moves toward the bottom of the housing 1 and drives the bending structures 400 to move closer to each other to clamp the aluminum alloy. Then, the stamping structure 300 continues to move to bend the aluminum alloy clamped by the bending structure 400, and then drives the adsorption structure 500 to adsorb the aluminum alloy initially clamped by the bending structure 400.

[0035] When the aluminum alloy is completely bent, the stamping structure 300 continues to move toward the bottom of the housing 1 and completely bends the aluminum alloy, and drives the adsorption structure 500 to move to increase the adsorption force on the aluminum alloy clamped by the bending structure 400, and when the stamping structure 300 completely stamps and bends the aluminum alloy, the surface of the adsorption structure 500 can prevent the aluminum alloy bent by the stamping structure 300 from slipping;

[0036] The present invention takes into account that, when stamping the aluminum alloy skylight mounting bracket, the staff needs to hold the aluminum alloy by hand and place it under the stamping machine, and then perform stamping and bending. Although the existing method can be bent and stamped, there will be a rebound phenomenon after the aluminum alloy is stamped and bent. Because in the single large-angle bending process, the material will be subjected to huge local pressure in the bending area. This high stress state will cause the material to rebound after bending. If rebound occurs, it will not only affect the assembly accuracy of the product but also affect the subsequent use performance. In addition, when stamping and bending the aluminum alloy, the aluminum alloy will warp in the unbent parts, thereby affecting the deviation of the aluminum alloy stamping and bending or failing to complete the stamping and bending. Therefore, by stamping the structure 300 Move toward the bottom of the housing 1, and drive the bending structures 400 to move closer to each other to clamp the aluminum alloy, thereby achieving clamping and limiting the aluminum alloy before bending, and preventing the aluminum alloy from detaching during bending. Then the stamping structure 300 continues to move and bend the aluminum alloy clamped by the bending structure 400, and then drives the adsorption structure 500 to adsorb the aluminum alloy initially clamped by the bending structure 400, thereby achieving initial bending of the aluminum alloy clamped by the bending structure 400. By gradually increasing the stress in the bending area of ​​the aluminum alloy, each stress is relatively small, thereby reducing the concentration of local stress of the aluminum alloy and reducing the possibility of springback. In addition, the aluminum alloy is further adsorbed to prevent the aluminum alloy from detaching due to the inability to clamp the bending structure 400 when the aluminum alloy is completely bent later.

[0037] In addition, when stamping the aluminum alloy, heat is generated at the stamped part. During the bending process of the aluminum alloy, the metal material is subjected to a huge external force, causing the atoms or molecules inside the material to shift. This displacement consumes energy, which is released in the form of heat, and causes the stamped part of the aluminum alloy to generate heat, making it easy to separate from the stamping die. Therefore, the stamping structure 300 continues to move toward the bottom of the shell 1 and completely bends the aluminum alloy, and drives the adsorption structure 500 to move to increase the adsorption force on the aluminum alloy clamped by the bending structure 400, thereby The adsorption force of the bending structure 400 is gradually enhanced according to the punching force of the punching structure 300, so as to prevent the punching force of the punching structure 300 from being too high and causing the unbent area of ​​the aluminum alloy to warp, thereby improving the bending effect. When the punching structure 300 completely punches and bends the aluminum alloy, the surface of the adsorption structure 500 can prevent the aluminum alloy bent by the punching structure 300 from slipping, thereby reducing the heat generated in the bent area of ​​the aluminum alloy and the separation from the punching structure 300, thereby improving the punching and bending effect of the aluminum alloy by the punching structure 300 and the bending structure 400;

[0038] In order to facilitate the stamping and bending of aluminum alloy, the following specific structure needs to be disclosed in detail, please refer to Figures 1 to 3The stamping structure 300 includes a telescopic rod 301, which is slidably connected to the output end of the cylinder 2. The telescopic rod 301 is slidably connected to the housing 1. An L-shaped inclined plate 302 is fixedly connected to the end of the telescopic rod 301 away from the cylinder 2. The surface of the L-shaped inclined plate 302 is fixedly connected to a limit rod 303 along the center of the telescopic rod 301. A stamping plate 304 is detachably installed on the side of the L-shaped inclined plate 302 away from the telescopic rod 301.

[0039] First, the staff needs to place the aluminum alloy to be stamped on the surface of the bending structure 400, and then manually start the remote control cylinder 2, and drive the telescopic rod 301 to move toward the bottom of the shell 1, and then drive the L-shaped inclined plate 302 to move toward the bottom of the shell 1, so that the inclined surfaces on both sides of the L-shaped inclined plate 302 move synchronously, which is convenient for the subsequent clamping and limiting of the aluminum alloy by the bending structure 400, and then when the L-shaped inclined plate 302 moves, the limiting rod 303 will be driven to slide inside the shell 1, so that the movement direction of the L-shaped inclined plate 302 can be limited, thereby improving the effect of subsequent stamping and bending. Since the height of the stamping plate 304 is lower than the inclined surfaces set on both sides of the L-shaped inclined plate 302, when the L-shaped inclined plate 302 moves toward the bottom of the shell 1, the two sides first contact with the bending structure 400 to limit and clamp the aluminum alloy, and then the movement of the L-shaped inclined plate 302 will drive the stamping plate 304 to move, which is convenient for the subsequent bending of the aluminum alloy after the bending structure 400 is clamped and limited;

[0040] In order for the bending structure 400 to clamp and limit the aluminum alloy and perform bending, the following specific structures need to be disclosed in detail, please refer to Figures 1 to 5 The bending structure 400 includes a first return spring 404, which is slidably connected to the side of the housing 1, one end of the first return spring 404 is fixedly connected to the first sliding plate 401, and the top of the first sliding plate 401 is fixedly connected to the wave block 402, and the side of the first sliding plate 401 close to the housing 1 is arranged as an inclined surface, and the inclined surface of the first sliding plate 401 and the inclined surface of the L-shaped inclined plate 302 are adapted to each other;

[0041] When the inclined surfaces on both sides of the L-shaped inclined plate 302 move toward the bottom of the shell 1, they will contact with the inclined surfaces of the first sliding plate 401 and drive the two groups of first sliding plates 401 to move closer to each other, and also drive the two groups of first return springs 404 to move toward the shell 1, so as to facilitate the subsequent resetting of the first sliding plate 401, and also synchronously drive the two groups of clamping plates 403 to move closer to each other, so that the two groups of clamping plates 403 will first clamp the aluminum alloy to prevent the subsequent stamping plate 304 from moving when bending the aluminum alloy, and then when the L-shaped inclined plate 302 continues to move toward the bottom of the shell 1, the inclined surface of the L-shaped inclined plate 302 will pass over the inclined surface of the first sliding plate 401, Even if the inclined surface of the L-shaped inclined plate 302 passes over the inclined surface of the first sliding plate 401, the first sliding plate 401 will also abut against the surface of the L-shaped inclined plate 302, so the first sliding plate 401 will not reset. Then the L-shaped inclined plate 302 continues to move toward the housing 1, which will drive the stamping plate 304 to contact and bend the aluminum alloy received by the first sliding plate 401. After the stamping plate 304 bends the aluminum alloy for a certain distance, the cylinder 2 stops moving, so that the aluminum alloy cannot continue to move and bend, so that the aluminum alloy is preliminarily bent. By gradually increasing the stress in the bending area of ​​the aluminum alloy, the stress each time will be relatively small, thereby reducing the concentration of local stress of the aluminum alloy and reducing the possibility of springback.

[0042] In order to achieve the phenomenon of warping of the unbent area when the aluminum alloy is bent, the following specific structure needs to be disclosed. The adsorption structure 500 includes a fixed plate 504, the fixed plate 504 is fixedly connected to the inner wall of the shell 1, and the surface of the fixed plate 504 on the side away from the shell 1 is fixedly connected to a second return spring 502, and the second return spring 502 is fixedly connected to the side away from the fixed plate 504. The surface of the fixed plate 504 is also slidably connected to a sliding column 503, and the surface of the sliding column 503 is rotatably connected to a swing rod 505 through a pin shaft, and the swing rod 505 is away from the sliding One side of the column 503 is rotatably connected with a second sliding plate 506 through a pin shaft, and the outer ring surface of the second sliding plate 506 is slidably connected to a limit plate 509, and a sliding groove that is mutually adapted to the second sliding plate 506 is opened inside the limit plate 509. The limit plate 509 is fixedly connected to the inner side wall of the housing 1, and a piston rod 508 is fixedly connected to the top of the second sliding plate 506. The outer ring surface of the piston rod 508 is slidably connected to a piston cylinder 507, and the outer ring surface of the piston cylinder 507 is fixedly connected to the wave block 402, and the piston cylinder 507 is fixedly connected to the inside of the first sliding plate 401;

[0043] When the bending structure 400 initially bends the aluminum alloy, the anti-slide plate 501 will be driven to move toward the bottom of the shell 1, and then the sliding column 503 will be driven to slide inside the fixed plate 504, so that the swing rod 505 swings a certain distance, and the second sliding plate 506 will be driven to slide in the slide groove provided inside the limit plate 509, and then the piston rod 508 will be driven to slide inside the piston cylinder 507, so that suction is generated inside the piston cylinder 507. At that time, since a plurality of groups of holes are provided on the surface of the wave block 402, and the piston cylinder 507 is fixedly connected with the wave block 402 through, when suction is generated inside the piston cylinder 507, the aluminum alloy plate received on the surface of the wave block 402 will be initially adsorbed, so as to prevent the stamping plate 304 from detaching when initially bending, and also to prevent the aluminum alloy from rebounding.

[0044] Next, when the stamping plate 304 is always against the aluminum alloy after the initial bending, the aluminum alloy can be prevented from rebounding. Then, when the bending is completely completed, the cylinder 2 will start to make the L-shaped inclined plate 302 and the stamping plate 304 continue to move. When the stamping plate 304 moves, the aluminum alloy will be completely bent, and the anti-slip plate 501 will be driven to move toward the bottom of the shell 1, and then the sliding column 503 will continue to slide inside the fixed plate 504 and slide to the bottom, and then the swing rod 505 will be driven to swing to a parallel state. For details, please refer to Fig. 9 , and in the process of the swing rod 505 swinging to the parallel state, it will drive the second sliding plate 506 to slide the maximum distance in the sliding groove opened inside the limit plate 509, and in the process of the second sliding plate 506 sliding the maximum distance, it will drive the piston rod 508 to slide the maximum distance in the piston cylinder 507, and then in the process of the piston rod 508 gradually sliding inside the piston cylinder 507, it will drive the piston cylinder 507 to gradually generate suction, and the aluminum alloy adsorbed on the surface of the wave block 402 will be adsorbed again. Because the stress generated when the aluminum alloy is completely bent will be very large, the suction generated inside the piston cylinder 507 will also gradually increase, thereby preventing the aluminum alloy adsorbed by the wave block 402 from being more stable, and even if the aluminum alloy is completely bent, the aluminum alloy cannot be moved;

[0045] In order to prevent the aluminum alloy from being completely bent, the aluminum alloy surface will generate heat and the stamping plate 304 will be separated from the aluminum alloy surface, the following specific structure needs to be disclosed in detail, please refer to 5 to Fig. 9 The surface of the anti-skid plate 501 is made of stainless steel for anti-skid setting, and the second return spring 502 fixedly connected to the bottom of the anti-skid plate 501 is symmetrically arranged in two groups along the center of the anti-skid plate 501;

[0046] When the stamping plate 304 bends the aluminum alloy plate, the anti-slide plate 501 will always be in contact with the aluminum alloy, and when the aluminum alloy is completely bent, a large amount of heat will be generated at the bent portion of the aluminum alloy. The anti-slide plate 501 is set to prevent the aluminum alloy from coming into contact with the anti-slide plate 501 and detaching. Then, two sets of second return springs 502 are set to improve the stability of the anti-slide plate 501 and prevent it from deflecting.

[0047] In order to better bend aluminum alloy, the following specific structure needs to be disclosed in detail, please refer to Figures 1 to 4 The limiting rod 303 is symmetrically arranged in two groups along the center of the telescopic rod 301. The limiting rod 303 is connected to the housing 1 in a through sliding manner. Both sides of the L-shaped inclined plate 302 fixedly connected to the bottom of the limiting rod 303 are inclined. Both sides of the L-shaped inclined plate 302 are provided with a sliding groove adapted to the first return spring 404;

[0048] When the inclined surfaces on both sides of the L-shaped inclined plate 302 drive the first sliding plate 401 to move, the first sliding plate 401 will also drive the first return spring 404 to slide inside the shell 1. In order not to affect the L-shaped inclined plate 302 to continue to slide toward the bottom of the shell 1, both sides of the L-shaped inclined plate 302 are provided with sliding grooves that are mutually adapted to the first return spring 404, so as not to affect the sliding of the L-shaped inclined plate 302. In addition, two groups of limit rods 303 are provided to more conveniently drive the movement of the L-shaped inclined plate 302, and can also limit the moving direction of the L-shaped inclined plate 302, thereby improving the stamping and bending effect of the subsequent stamping plate 304.

[0049] In order to better realize the stamping and bending of aluminum alloy, the following specific structures need to be disclosed in detail, please refer to Figures 1 to 7 The bottom of the first sliding plate 401 is slidably connected to the adsorption structure 500, and the wave blocks 402 fixedly connected to the top of the first sliding plate 401 are respectively arranged in five groups along the surface of the first sliding plate 401, and the surface of the first sliding plate 401 is provided with a plurality of groups of holes, and the first sliding plate 401, the wave blocks 402, the clamping plate 403 and the first return spring 404 are symmetrically arranged in two groups along the center of the housing 1;

[0050] When the stamping plate 304 stamps and bends the aluminum alloy, due to the arrangement of the two sets of bending structures 400, the aluminum alloy can be bent into a U shape, so that it can be better installed with the aluminum alloy skylight later, and when the stamping plate 304 bends the aluminum alloy, holes are opened on the surface of the wave block 402, which makes it easier to adsorb the aluminum alloy, thereby improving the aluminum alloy bending into a U shape, and two sets of clamping plates 403 are arranged, which can also clamp and limit the two sides of the aluminum alloy, thereby further improving the position of the limited aluminum alloy;

[0051] In order to better achieve the adsorption of aluminum alloy, the following specific structures need to be disclosed in detail: springs are arranged inside the sliding column 503 and the fixed plate 504; two groups of swing rods 505 connected by pins are arranged on the surface of the sliding column 503; a second sliding plate 506 connected by a pin on the side of the swing rod 505 away from the sliding column 503 is slidably connected to a slide groove opened at the bottom of the first sliding plate 401; the second sliding plate 506 close to the side of the first sliding plate 401 is fixedly connected to the piston rod 508; and two groups of piston rods 508 and piston cylinders 507 are arranged, and both are fixedly connected to the wave block 402 through penetration;

[0052] When the anti-slip plate 501 moves toward the bottom of the shell 1, the two groups of swing rods 505 will swing and drive the second sliding plate 506 to move in the sliding groove opened at the bottom of the first sliding plate 401 and also move in the sliding groove opened on the surface of the limiting plate 509. Therefore, when the second sliding plate 506 moves, it will drive the two groups of piston rods 508 to slide inside the piston cylinder 507, so that suction is gradually generated on the surface of the wave block 402, thereby improving the adsorption effect of the wave block 402.
