Description

Technical Field

[0001] This invention relates to the field of metal material processing technology, specifically to a metal material frame bending and stamping equipment. Background Technology

[0002] Metal frame bending and stamping equipment is a processing technology that integrates the stamping, bending, and shaping processes of metal sheets into a single process through an integrated bending and stamping machine. The core technology uses a single positioning reference to achieve continuous processing of multiple features, effectively avoiding the positioning errors and cumbersome process connections of traditional sequential processing. At the same time, it is suitable for the integrated molding requirements of complex frame structures and is widely used in industrial equipment frames, automotive parts frames, home appliance frames, and other fields. It is a core processing equipment that takes into account both mass production and customized research and development.

[0003] During use, after stamping, the frame body undergoes elastic rebound or plastic deformation in whole or in part, resulting in a tight seal between the frame body's outline and the mold surface. A negative pressure adsorption effect is formed in the sealed cavity. At the same time, the local protrusions and corner squeezing caused by deformation further increase the frictional resistance of the contact surface, causing the frame body to get stuck on the mold surface and making it difficult to remove manually.

[0027] Preferably, the sliding tooth assembly includes two sliding tooth rings 2 that are rotatably connected to the outer wall of the fixed shaft, two rotating rings 2 that are rotatably connected to the outer wall of the fixed shaft, two telescopic rods 2 that are fixedly connected to the outer wall of each of the two rotating rings 2, two spring pieces that are rotatably connected to the outer wall of the fixed shaft, and limit grooves that are formed on the outer wall of each of the two sliding tooth rings 2.

[0028] Among them, the two sliding tooth rings 2 are provided with sliding teeth on the side close to the sliding tooth ring 1. The sliding teeth on the sliding tooth ring 1 are adapted to the sliding teeth on the sliding tooth ring 2. The telescopic rod 2 is adapted to the limiting groove respectively. The sliding tooth ring 2 slides on the outer wall of the rotating ring 2. The spring piece is located between the rotating ring 2 and the sliding tooth ring 2.

[0029] Preferably, the lifting assembly includes a top block slidably connected to the inner wall of the fixed housing, and two springs are fixedly connected to the bottom of the top block;

[0030] Among them, the two springs are fixedly connected to the fixed shell on the side away from the top block, and the two springs are set in a mirror image. The telescopic rod is rotatably connected to the top block on the side away from the fixed axis.

[0031] Preferably, the friction assembly includes two push rods fixedly connected to the outer wall of the top block, a rotating shaft rotatably connected to the outer wall of the top block, and a friction plate rotatably connected to the outer wall of the rotating shaft;

[0032] The two push rods are set in a mirror image, and the inclined surface of the friction plate is set as the friction surface.

[0033] The present invention has the following beneficial effects:

[0034] (1) When the bending machine bends the frame material, the two sides of the frame material present an arc-shaped movement trajectory. When the two sides of the frame material are bent, the sliding plate is pressed to slide downward. The sliding plate drives the rotating ring one to rotate counterclockwise on the fixed shaft, which drives the sliding tooth ring one to rotate clockwise. The sliding tooth ring one drives the sliding tooth ring two to rotate clockwise in the same direction, which will drive the rotating ring two to rotate clockwise, thereby driving the top block to move downward. When the frame completely passes the sliding plate, the sliding plate can move upward to lift the frame, so that the frame is separated from the mold. Through the application of the above components, the problem of elastic rebound or plastic deformation of the frame as a whole or part after stamping is effectively reduced, which causes the outline of the frame after forming to form a tight seal with the mold surface, and the frame stuck on the mold surface.

[0035] (2) This invention utilizes the characteristic of the above-mentioned device that the sliding tooth ring one drives the sliding tooth ring two to rotate. When the sliding tooth ring one rotates clockwise, the sliding teeth between the sliding tooth ring one and the sliding tooth ring two do not slip. When the frame passes the sliding plate, the limit plate moves up, thereby driving the rotating ring one to rotate clockwise, and then driving the sliding tooth ring one to rotate counterclockwise. At this time, the sliding teeth between the sliding tooth ring one and the sliding tooth ring two will slip, and the sliding tooth ring one cannot drive the sliding tooth ring two to rotate. When the top block moves upward, such as Figure 7 As shown, at this time, the sliding ring 2 moves to the left under the influence of the sliding teeth, slides on the outer wall of the rotating ring 2, and presses the spring piece to change from a free state to a compressed state, and then from a compressed state to a free state. This state change is affected by the sliding teeth, and this state cycle is repeated. That is, when the slide plate moves upward and the top block moves upward, they are independent. The upward movement of the slide plate will not affect the upward movement of the top block. Through the application of the above components, the problem of the slide plate moving upward and causing the top block to move upward after completing its work is effectively prevented from impacting the frame and causing the frame to be scratched and deformed.

[0036] (3) This invention utilizes the characteristic of the top block of the above-mentioned device moving up and down. Since the friction plate is set with an included angle between its two sides, when the second spring moves downward, the friction surface of the friction plate does not contact the limiting plate, and the smooth surface of the friction plate contacts the top block. At this time, the friction surface only has a very small area in contact with the limiting plate. When the top block moves upward, since the friction surface of the friction plate has a very small area in contact with the limiting plate, the friction plate will rotate on the rotating shaft with this contact surface as the fulcrum. The friction surface of the friction plate is always in contact with the limiting plate, and the smooth surface of the friction plate does not contact the top block. At this time, the top block will move upward at a slower speed than downward, so that when the press presses the frame, the top block will not quickly contact the frame. Through the application of the above components, the problem of the top block quickly contacting the frame and pressing against the frame when the press presses the frame, and the bending part of the frame being deformed by the pressure of the top block is effectively prevented.

[0037] (4) The present invention utilizes the feature of the top block of the above-mentioned equipment moving upward. When the top block contacts the frame, the top rod simultaneously contacts the bent part of the frame. After the press leaves the frame and maintains a certain distance from the frame, the top block begins to lift the bent part of the frame, and the part of the top rod away from the top block lifts the corner of the bent part of the frame. Through the application of the above components, the problem of the frame bending part being subjected to additional force from the top block when the top block lifts the frame due to the springback at the bent part of the frame, and the springback being strengthened, is effectively prevented. After the stress is released, the product does not meet the bending angle requirements. Attached Figure Description

[0050] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0051] Example 1, please refer to Figures 1-3 This invention relates to a metal frame bending and stamping equipment, comprising a machine base 13, a stamping machine 14 fixedly connected to the top of the machine base 13, a bending machine 15 fixedly connected to the outer wall of the stamping machine 14, and a fixed platform 16 fixedly connected to the inner wall of the machine base 13, and further comprising:

[0054] Lifting mechanism 3 is slidably disposed inside fixed component 11;

[0055] The workers place the frame material on the machine 13, then start the stamping machine 14. When the stamping machine 14 is close to the frame material and completes the stamping of part of the position, the two bending machines 15 are started to bend the frame material at the required position. After the bending is completed, the stamping machine 14 and the bending machine 15 are lifted and the finished product is removed.

[0056] Fixed mechanism 1 includes:

[0057] Fixing component 11 is fixedly connected to the top of the fixing platform 16;

[0058] The sliding component 12 is slidably connected to the inner wall of the fixed component 11.

[0059] Rotating mechanism 2 includes:

[0061] The sliding tooth assembly 22 is rotatably connected to the outer wall of the sliding assembly 12.

[0063] Lifting component 31 is slidably connected to the inner wall of fixed component 11;

[0064] Friction assembly 32 is rotatably connected to the outer wall of lifting assembly 31.

[0065] Example 2, please refer to Figures 4-8 The present invention is a metal frame bending and stamping equipment. Based on Example 1, the fixing component 11 includes two fixing shells 111 fixedly connected to the top of the fixing platform 16, two limiting plates 112 fixedly connected to the top of the fixing platform 16, and a sliding plate 113 slidably connected to the inner wall of the fixing shell 111.

[0066] The two fixed shells 111 are arranged in a mirror image, and a limit plate 112 is fixedly connected to the side of the two fixed shells 111 that is close to each other.

[0067] The sliding assembly 12 includes a fixed shaft 121 fixedly connected to the inner wall of the fixed housing 111. Two rotating rings 122 are rotatably connected to the outer wall of the fixed shaft 121. Telescopic rods 123 are fixedly connected to the outer walls of the two rotating rings 122. The side of the two telescopic rods 123 away from the rotating rings 122 is rotatably connected to the slide plate 113. Two springs 124 are fixedly connected to the bottom of the slide plate 113.

[0068] Among them, the two rotating rings 122 are arranged in a mirror image, the telescopic rod 123 is fixed to the rotating ring 122, the telescopic joint rotates with the limiting plate 112, and the side of the spring 124 away from the slide plate 113 is fixedly connected to the fixed shell 111.

[0069] The lever assembly 21 includes two sliding toothed rings 211 rotatably connected to the outer wall of the fixed shaft 121. The outer wall of the fixed shaft 121 is provided with several connecting plates 212. The outer wall of the rotating ring 212 is fixedly connected to the two connecting plates 212. The outer wall of the sliding toothed ring 211 is fixedly connected to the two connecting plates 212. The outer walls of the several connecting plates 212 are rotatably connected to two telescopic connecting rods 213. The outer wall of the fixed shaft 121 is fixedly connected to two telescopic connecting rods 214.

[0070] Among them, the sliding tooth ring 211 is provided with sliding teeth on the side away from the rotating ring 122, the two telescopic connecting rods 214 are arranged in a circumferential array, the two connecting plates 212 on the outer wall of the rotating ring 122 correspond to the two connecting plates 212 on the outer wall of the sliding tooth ring 211, the two ends of the telescopic connecting rod 213 are ball-jointed with the connecting plates 212, the fixed cylinder of the telescopic connecting rod 214 is fixedly connected to the fixed shaft 121, and the telescopic joint of the telescopic connecting rod 213 is ball-jointed with the fixed cylinder of the connecting plate 212.

[0071] The sliding tooth assembly 22 includes two sliding tooth rings 221 rotatably connected to the outer wall of the fixed shaft 121, two rotating rings 222 rotatably connected to the outer wall of the fixed shaft 121, telescopic rods 223 fixedly connected to the outer walls of the two rotating rings 222, two spring pieces 224 rotatably connected to the outer wall of the fixed shaft 121, and limit grooves 225 formed on the outer walls of the two sliding tooth rings 221.

[0072] Among them, the two sliding tooth rings 221 are provided with sliding teeth on the side near the sliding tooth ring 211. The sliding teeth on the sliding tooth ring 211 are adapted to the sliding teeth on the sliding tooth ring 221. The telescopic rod 223 is adapted to the limiting groove 225 respectively. The sliding tooth ring 221 slides on the outer wall of the rotating ring 222. The spring piece 224 is located between the rotating ring 222 and the sliding tooth ring 221.

[0073] When the bending machine 15 bends the frame material, the two sides of the frame material exhibit an arc-shaped movement trajectory. As the frame material bends, it first contacts the sliding plate 113. Because the top of the sliding plate 113 is arc-shaped, the frame material compresses the sliding plate 113 downwards, thereby compressing the two springs 124, causing the springs 124 to change from a free state to a compressed state. Figure 6 As shown, when the slide plate 113 moves downward, the slide plate 113 drives the rotating ring 122 to rotate counterclockwise on the fixed shaft 121. Since the telescopic connecting rod 213 is ball-connected to the connecting plate 212, when the rotating ring 122 rotates counterclockwise, the left connection point of the telescopic connecting rod 213 rotates clockwise relative to the fixed shaft 121. This causes the telescopic connecting rod 213 to rotate with the connection point of the telescopic connecting rod 214 and the telescopic connecting rod 213 as the fulcrum, thereby lifting the sliding tooth ring 211 to rotate clockwise. Since the telescopic connecting rod 214 and the telescopic connecting rod 213 are fixed... The fixed cylinder is connected, and the distance between this connection point and the rotating ring 122 is greater than the distance between the connection point and the sliding ring 211. Therefore, when the rotating ring 122 rotates at a certain angle, the sliding ring 211 can rotate at a faster speed and a larger angle. During rotation, the telescopic joint of the telescopic link 123 is stretched, and the telescopic link 214 is compressed. When the sliding ring 211 rotates clockwise, the sliding teeth on the sliding ring 121 and the sliding teeth on the sliding ring 221 will not slide. Therefore, the sliding ring 121 drives the sliding ring 221 to rotate clockwise in the same direction.

[0074] When the first sliding ring 211 rotates clockwise, the sliding teeth between the first sliding ring 211 and the second sliding ring 221 do not slip. When the frame passes the slide plate 113, the limiting plate 112 moves upward, thereby causing the first rotating ring 122 to rotate clockwise, and then causing the first sliding ring 211 to rotate counterclockwise. At this time, the sliding teeth between the first sliding ring 211 and the second sliding ring 221 will slip, and the first sliding ring 211 cannot drive the second sliding ring 221 to rotate. When the top block 311 moves upward, it causes the second telescopic rod 223 and the second rotating ring 222 to rotate counterclockwise. The telescopic rod 223 moves within the limiting groove 225, which in turn causes the second sliding ring 221 to rotate counterclockwise. Because the sliding teeth between the second sliding ring 221 and the connecting plate 212 slip, ... Figure 7As shown, at this time, the sliding ring 221 moves to the left due to the influence of the sliding teeth, slides on the outer wall of the rotating ring 222, and presses the spring piece 224 to change from a free state to a compressed state, and then from a compressed state to a free state. This state change is affected by the sliding teeth, and this state cycle is generated repeatedly.

[0075] The lifting assembly 31 includes a top block 311 that is slidably connected to the inner wall of the fixed shell 111, and two springs 312 are fixedly connected to the bottom of the top block 311.

[0076] Among them, the two springs 312 are fixedly connected to the fixed shell 111 on the side away from the top block 311, and the two springs 312 are arranged in a mirror image. The telescopic rod 223 is rotatably connected to the top block 311 on the side away from the fixed shaft 121.

[0077] The friction assembly 32 includes two push rods 321 fixedly connected to the outer wall of the top block 311, a rotating shaft 322 rotatably connected to the outer wall of the top block 311, and a friction plate 323 rotatably connected to the outer wall of the rotating shaft 322.

[0078] Among them, the two push rods 321 are arranged in a mirror image, and the inclined surface of the friction plate 323 is set as the friction surface;

[0079] Because the friction plate 323 is designed with an included angle on both sides, when the second spring 312 moves downward, the friction surface of the friction plate 323 does not contact the limiting plate 112, and the smooth surface of the friction plate 323 contacts the top block 311. At this time, only a very small area of ​​the friction surface contacts the limiting plate 112. When the top block 311 moves downward, the smooth surface of the friction plate 323 can always contact the top block 311. When the top block 311 moves upward, because the friction surface of the friction plate 323 has a very small area of ​​contact with the limiting plate 112, the friction plate 323 will rotate on the rotating shaft 322 with this contact surface as the fulcrum. The friction surface of the friction plate 323 will always contact the limiting plate 112, and the smooth surface of the friction plate 323 will not contact the top block 311. At this time, the top block 311 will move upward at a slower speed than downward, so that when the press 14 presses the frame, the top block 311 will not quickly contact the frame.

[0080] When the top block 311 contacts the frame, the top rod 321 simultaneously contacts the bent part of the frame. After the press 14 leaves the frame and maintains a certain distance from the frame, the top block 311 begins to lift the bent part of the frame, and the part of the top rod 321 away from the top block 311 lifts the corner of the bent part of the frame.

[0081] A specific application of this embodiment is as follows: When in use, the staff places the frame material on the machine table 13, and then starts the stamping machine 14. When the stamping machine 14 is close to the frame material and completes the stamping of part of the position, the two bending machines 15 are started to bend the frame material at the required position.

[0082] When the bending machine 15 bends the frame material, the two sides of the frame material exhibit an arc-shaped movement trajectory. As the frame material bends, it first contacts the sliding plate 113. Because the top of the sliding plate 113 is arc-shaped, the frame material compresses the sliding plate 113 downwards, thereby compressing the two springs 124, causing the springs 124 to change from a free state to a compressed state. Figure 6 As shown, when the slide plate 113 moves downward, it causes the rotating ring 122 to rotate counterclockwise on the fixed shaft 121. Since the telescopic connecting rod 213 is ball-connected to the connecting plate 212, when the rotating ring 122 rotates counterclockwise, the left connection point of the telescopic connecting rod 213 rotates clockwise relative to the fixed shaft 121. This causes the telescopic connecting rod 213 to rotate with the connection point of the telescopic connecting rod 214 and the telescopic connecting rod 213 as the fulcrum, thereby lifting the sliding ring 211. When rotating clockwise, because the telescopic link 214 is connected to the fixed cylinder of the telescopic link 213, and the distance between this connection point and the rotating ring 122 is greater than the distance to the sliding ring 211, when the rotating ring 122 rotates a certain angle, the sliding ring 211 can rotate at a faster speed and a larger angle. During rotation, the telescopic joint of the telescopic link 213 is stretched, and the telescopic link 214 is compressed. When the sliding ring 211 rotates clockwise, the sliding ring 211... The sliding teeth on the sliding tooth ring 221 will not slide, so the sliding tooth ring 211 drives the sliding tooth ring 221 to rotate clockwise. Since the limiting groove 225 restricts the telescopic rod 223, the sliding tooth ring 221 will also drive the rotating ring 222 to rotate clockwise, which will drive the top block 311 to move downward. The two springs 312 change from free state to compressed state. When the frame completely passes the slide plate 113, the spring 124 changes from compressed state to free state, and the slide plate 113 can move upward. The bent part of the frame is completely above the top block 311. At this time, the two springs 312 change from compressed state to free state, and the top block 311 lifts the frame, so that the frame is separated from the mold. This effectively reduces the problem that after stamping, the frame as a whole or part will have elastic rebound or plastic deformation, which will cause the frame to form a tight seal with the mold surface after forming, and the frame will be stuck on the mold surface.

[0083] Utilizing the characteristic of the aforementioned device that the sliding tooth ring 211 drives the sliding tooth ring 221 to rotate, when the sliding tooth ring 211 rotates clockwise, the sliding teeth between the sliding tooth ring 211 and the sliding tooth ring 221 do not slip. When the frame passes the sliding plate 113, the limiting plate 112 moves upward, thereby driving the rotating ring 122 to rotate clockwise, and then driving the sliding tooth ring 211 to rotate counterclockwise. At this time, the sliding teeth between the sliding tooth ring 211 and the sliding tooth ring 221 will slip, and the sliding tooth ring 211 cannot drive the sliding tooth ring 221 to rotate. When the top block 311 moves upward, it drives the telescopic rod 223 and the rotating ring 222 to rotate counterclockwise. The telescopic rod 223 moves within the limiting groove 225, which in turn drives the sliding tooth ring 221 to rotate counterclockwise. Because the sliding teeth between the sliding tooth ring 221 and the connecting plate 212 slip, ... Figure 7 As shown, at this time, the sliding ring 221 moves to the left due to the influence of the sliding teeth, slides on the outer wall of the rotating ring 222, and presses the spring 224 to change from a free state to a compressed state, and then from a compressed state to a free state. This state change is affected by the sliding teeth, and this state cycle is repeated. That is, when the slide plate 113 moves upward, it is independent of the upward movement of the top block 311. The upward movement of the slide plate 113 will not affect the upward movement of the top block 311, which effectively prevents the slide plate 113 from moving upward and causing the top block 311 to move upward after completing its work, thus preventing the frame from being scratched and deformed.

[0084] Utilizing the characteristic of the top block 311 moving up and down, and because the friction plate 323 is designed with an included angle on both sides, when the spring 312 moves downward, the friction surface of the friction plate 323 does not contact the limiting plate 112, but the smooth surface of the friction plate 323 contacts the top block 311. At this time, only a very small area of ​​the friction surface contacts the limiting plate 112. When the top block 311 moves downward, the smooth surface of the friction plate 323 can always contact the top block 311. When the top block 311 moves upward, the friction surface of the friction plate 323 has a very small contact area with the limiting plate 112. At this time, the friction plate 323 will rotate on the rotating shaft 322 with this contact surface as the fulcrum. The friction surface of the friction plate 323 is always in contact with the limiting plate 112, and the smooth surface of the friction plate 323 does not contact the top block 311. At this time, the top block 311 will move upward at a slower speed than downward, so that when the press 14 presses the frame, the top block 311 will not quickly contact the frame. This effectively prevents the problem that when the press 14 presses the frame, the top block 311 will quickly contact the frame and press against the frame, and the bent part of the frame will be deformed due to the pressure of the top block 311.

[0085] Utilizing the upward movement of the top block 311 in the aforementioned equipment, when the top block 311 contacts the frame, the top rod 321 simultaneously contacts the bent portion of the frame. After the press 14 moves away from the frame and maintains a certain distance from it, the top block 311 begins to lift the bent portion of the frame, and the portion of the top rod 321 away from the top block 311 lifts the corner of the bent portion of the frame. This effectively prevents the problem that due to the springback at the bent portion of the frame, when the top block 311 lifts the frame, the bent portion of the frame is subjected to additional force from the top block 311, the springback is strengthened, and the product fails to meet the bending angle requirements after the stress is released.
