Description

Technical Field

[0001] The invention relates to the technical field of automobile hinge production, in particular to a non-indentation bending device for automobile hinge processing. Background Art

[0002] A car hinge is a mechanical device used to connect two solid bodies and allow them to rotate relative to each other. It is mainly used to connect car doors, engine hoods, trunk lids, fuel tank caps and other parts.

[0003] The main function of automobile hinges is to ensure that car doors, engine hoods and other parts can be opened and closed smoothly, and at the same time have a buffering effect to reduce the noise generated by the collision with the car body when closing. This type of hinge plays a vital role in automobiles, not only ensuring the normal use of vehicle components, but also improving the driving and riding comfort. Depending on the structural design, automobile hinges have two common styles: stamping and casting. Among them, cast hinges are usually thicker than stamped hinges. In addition, there is also an elastic hinge, which consists of an outer tube, a rubber bushing and an inner tube. It has the functions of mitigating impact, isolating vibration and not transmitting noise. This type of hinge is often used in the suspension position of the car.

[0004] At present, since different automobile hinge models require different material sheet models, it is necessary to adjust the distance between the clamping devices according to the material sheet model during stamping and bending to clamp the material sheet to prevent tilting during stamping and bending, which may cause deformation of the material sheet. Summary of the invention

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: a non-indentation bending device for automobile hinge processing, comprising an operating table, the operating table is used for stably placing the bending member, a fixing frame is fixedly connected to one side of the outer surface of the operating table, a support seat is fixedly connected to the outer surface of the fixing frame, and an extension frame is fixedly connected to the upper surface of the fixing frame; A forming component, which is used for positioning and bending the sheet; A stamping part, which is used for bending and forming materials, a hydraulic cylinder is fixedly installed on the top of the stamping part, a collar is fixedly installed on the top of the hydraulic cylinder, support blocks are fixedly installed on both sides of the outer surface of the collar, and a clamping frame is fixedly installed on the top of the support block; A stabilizing component, which is used to clamp and fix the molding component and the material plate; The forming component is fixedly installed in the middle of the interior of the operating table, the stabilizing component is mounted on the outer surface of the forming component, and the stabilizing component is fixedly connected to the operating table, and the stamping part and the forming component are arranged on the same central axis; the staff places the material plate above the connecting block, and then adjusts the position of the pushing frame so that the material plate and the two sides of the arc pressing plate are against each other. Since the arc pressing plate is arranged as a structural fruit, the material plate can be stably clamped between the arc pressing plates, and the hydraulic cylinder drives the stamping part to punch downward as a transmission. Before stamping and bending, the staff pushes the pushing frame to slide on the surface of the operating table, so that the pushing frame drives the card plate and the forming component to be squeezed, and the push rod pushes the outer side of the arc pressing plate to slide on the surface of the connecting block, and adjusts the sliding position according to the width of the material plate, thereby fixing the material plate to prevent tilting during stamping and bending.

[0006] The stabilizing assembly includes a pad, and the upper surface of the pad is threaded with fixed short rods on both sides, the pad is slidably connected to the surface of the external rod, the surface of the pad is fixedly connected to a fixed seat, the outer surface of the fixed seat is rotatably connected to a rotating block on both sides, and the inner surface of the pad is rotatably connected to a spring push block. After the stamping and bending is completed, the staff rotates the rotating block to make the extension block in the pad move the spring sheet. Since the spring sheet is connected to the pushing frame, when the spring sheet bounces upward and generates friction with the rotating slider, the fitting position between the fitting groove and the sliding shaft changes, so that the fitting groove is away from the surface of the sliding shaft, and the top rod cancels the pushing of the arc pressure plate, so that the arc pressure plate is reset.

[0007] The forming assembly includes a bottom block, which is fixedly connected to the inside of the operating table. Positioning holes are provided on the surface of the bottom block. Arc pressure plates are frictionally connected on both sides of the outer surface of the bottom block. A connecting block is slidably connected between the opposite surfaces of the arc pressure plates. A center groove is provided on the surface of the connecting block. The material plate is clamped between the arc pressure plates, and the arc pressure plates are pushed from the outside and slide on the surface of the connecting block. At this time, the arc pressure plates are clamped on the surface of the material plate from both sides. Since the arc pressure plates are connected to the external connecting rods, when the position of the arc pressure plates moves, the external connecting rods are affected by the arc pressure plates to retract inward, causing the middle part to bend downward, and the bending angle is affected by the width of the material plate, so that different types of material plates can be fixed, which is convenient for processing, stamping and bending of different types of material plates, thereby improving the flexibility of the equipment. Since the plates are restricted by the arc pressure plates on both sides, the middle part of the material is concave downward when the plate is stamped. At this time, the V-shaped arc pressure plate is affected by the deformation of the material plate and slides on the surface of the connecting block, and the lower part of the arc pressure plate expands outward, so that the bent material plate falls into the bottom block, so that the material plate can be taken out after forming.

[0008] External connecting rods are fixedly connected to both sides of the outer surface of the arc pressing plate, and the surface of the external connecting rod is fixedly connected to a connecting shaft, and a sliding shaft is rotatably connected between the opposite surfaces of the connecting shaft. When the pushing frame drives the card plate to move, the fitting groove fits on the surface of the sliding shaft. Since the fitting groove has a card slot shape and the inside is made of elastic material, it can be tightly clamped on the surface of the sliding shaft, thereby limiting the position of the card plate after pushing, improving the stability of the stamping and bending equipment, fixing the arc pressing plate during stamping and bending, and preventing the material plate from sliding and deviating during stamping and bending.

[0009] The lower surface of the push block is fixedly connected with a pushing frame, and the inner surface of the pushing frame is fixedly connected with a clamping plate, and the clamping plate is slidably connected to the surface of the operating table. The surface of the pushing frame is penetrated by a push rod, and the push rod extends to the surface of the clamping plate. The pushing frame is slidably arranged on the surface of the operating table, and the staff pushes and squeezes from both sides to make the pushing frame drive the clamping plate to slide toward the surface of the sliding shaft, and uses the push rod to squeeze the arc pressing plate during the sliding process, so that the arc pressing plate slides on the surface of the connection block, and the pushing frame stops sliding after being limited by the material plate and clamps the clamping plate on the surface of the sliding shaft.

[0010] The pushing frame comprises a slide plate, the surface of the slide plate is fixedly connected with a slide frame, the surface of the slide frame is provided with a through hole, and the through hole is sleeved on the surface of the push rod.

[0011] The surface of the slide close to the slide plate is rotatably connected to a first round rod, and the surface of the slide away from the first round rod is rotatably connected to a second round rod. The first round rod and the second round rod are adapted to the clamping plate.

[0012] The cushion block includes a circular plate, the inner surface of which is fixedly connected to a rotating rod, the surface of which is fixedly connected to a limit block, and the outer surface of the limit block is provided with extension blocks on both sides, and the extension blocks are fixedly connected to the surface of the rotating block. When the staff rotates the rotating block, the rotating block is connected to the extension block, and the rotating block rotates upward from bottom to top, thereby causing the extension block to be pushed upward, so that the push block is lifted upward by the extension block, and a slide plate is connected below the push block, so when the push block is lifted upward, it drives the slide plate to move upward.

[0013] The surface of the limit block away from the rotating rod is fixedly connected with an external groove, and the inner surface of the external groove is slidably connected with a rotating slider, and the rotating slider is adapted to the elastic push block.

[0014] The push block includes a sleeve block, which is rotatably connected to the surface of the rotating rod, a spring sheet is fixedly connected to the surface of the sleeve block, and bending blocks are frictionally connected to the outer surfaces of the spring sheet on both sides, and an arc sheet is fixedly connected to the surface of the spring sheet, and a connecting plate is fixedly connected to the surface of the arc sheet, and the connecting plate is slidably connected to the surface of the slide plate. The sleeve block is sleeved on the surface of the rotating rod. When the extension block moves the bending block, the bending block is pushed and deformed, and the spring sheet is lifted upward, and the arc sheet and the connecting plate are moved upward. Since the arc sheet is made of elastic material, the pushing frame will drop the arc sheet downward when moving upward, so that the pushing frame will be slightly lifted, so that the fitting point between the fitting groove and the sliding shaft is changed, which is convenient for resetting the stable component. After the stamping and bending are completed, the clamping of the material sheet is relaxed, which is convenient for taking out the material sheet.

[0015] The present invention provides a non-indentation bending device for automobile hinge processing, which has the following beneficial effects: 1. The indentation-free bending equipment for automobile hinge processing is that the staff places the material plate on the top of the connecting block, and then the staff adjusts the position of the pushing frame so that the material plate and the two sides of the arc pressing plate are against each other. Since the arc pressing plate is set as a V-shaped structure, the material plate can be stably clamped between the arc pressing plates. The hydraulic cylinder drives the stamping parts to punch downward as a transmission. Before stamping and bending, the staff pushes the pushing frame to slide on the surface of the operating table, so that the pushing frame drives the card plate and the forming component to produce extrusion. The push rod pushes the outer side of the arc pressing plate to slide on the surface of the connecting block, and adjusts the sliding position according to the width of the material plate, so as to fix the material plate to prevent it from tilting during stamping and bending.

[0016] 2. The indentation-free bending equipment for automobile hinge processing drives the card plate to move through the pushing frame, and the fitting groove fits on the surface of the sliding shaft. Since the structure of the fitting groove is in the shape of a card slot and the interior is made of elastic material, it can be tightly clamped on the surface of the sliding shaft, thereby limiting the position of the card plate after pushing, improving the stability of the stamping and bending equipment, fixing the arc pressure plate during stamping and bending, and preventing the material plate from sliding and deviating during stamping and bending.

[0017] 3. The indentation-free bending equipment for automobile hinge processing inserts the material plate into the positioning hole in the bottom block. The arc pressing plate is pushed from the outside and slides on the surface of the connecting block. At this time, the arc pressing plate is clamped on the surface of the material plate from both sides. Since the arc pressing plate is connected to the external connecting rod, when the position of the arc pressing plate moves, the external connecting rod is affected by the inward contraction of the arc pressing plate and bends downward in the middle. The bending angle is affected by the width of the material plate, so that different types of material plates can be fixed, which is convenient for processing, stamping and bending of different types of material plates, and improves the flexibility of the equipment.

[0018] 4. The indentation-free bending equipment for automobile hinge processing, after the stamping and bending is completed, the staff rotates the rotating block to make the extension block in the pad block move the spring piece. Since the spring piece is connected to the pushing frame, when the spring piece bounces upward and generates friction with the rotating slider, the fitting position between the fitting groove and the sliding shaft changes, so that the fitting groove is away from the surface of the sliding shaft, and the push rod cancels the pushing of the arc pressure plate, so that the arc pressure plate is reset.

[0019] 5. The indentation-free bending equipment for automobile hinge processing is installed on the surface of the rotating rod through the sleeve block. When the extension block moves the bending block, the bending block is pushed and deformed, and drives the spring piece to lift upward, and drives the arc piece and the connecting plate to move up. Since the arc piece is made of elastic material, the pushing frame will drop the arc piece downward when moving upward, so that the pushing frame will be slightly lifted, so that the fitting point between the fitting groove and the sliding shaft will change, which is convenient for resetting the stable component. After the stamping and bending are completed, the clamping of the material plate is relaxed to facilitate the removal of the material plate. BRIEF DESCRIPTION OF THE DRAWINGS

Many modifications and changes are obvious to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and design various embodiments with various modifications suitable for specific purposes.

[0023] The first embodiment, as Figure 1-Figure 2 As shown, the present invention provides a technical solution: a non-indentation bending device for automobile hinge processing, comprising an operating table 5, the operating table 5 is used for stably placing the bending member, a fixing frame 10 is fixedly connected to one side of the outer surface of the operating table 5, a supporting seat 11 is fixedly connected to the outer surface of the fixing frame 10, and an extension frame 9 is fixedly connected to the upper surface of the fixing frame 10; A forming component 6, which is used for positioning and bending the sheet; A stamping part 8, which is used for bending and forming a sheet metal, a hydraulic cylinder 2 is fixedly installed on the top of the stamping part 8, a collar 7 is fixedly installed on the top of the hydraulic cylinder 2, support blocks 3 are fixedly installed on both sides of the outer surface of the collar 7, and a clamping frame 1 is fixedly installed on the top of the support block 3; A stabilizing component 4, which is used to clamp and fix the forming component 6 and the material plate; The forming component 6 is fixedly installed in the middle of the inner part of the operating table 5, the stabilizing component 4 is mounted on the outer surface of the forming component 6, and the stabilizing component 4 is fixedly connected to the operating table 5, and the stamping part 8 and the forming component 6 are arranged on the same central axis; the staff places the material plate above the connecting block 65, and then the staff adjusts the position of the pushing frame 45 so that the material plate and the arc pressing plate 63 are against each other on both sides. As the arc pressing plate 63 is set in a V-shape, the material plate can be stably clamped between the arc pressing plates 63. The hydraulic cylinder 2 is used as a transmission to drive the stamping part 8 to punch downward. Before stamping and bending, the staff pushes the pushing frame 45 to make the pushing frame 45 slide on the surface of the operating table 5, so that the pushing frame 45 drives the card plate 43 and the forming component 6 to produce extrusion, and the push rod 44 pushes the outer side of the arc pressing plate 63 to make the arc pressing plate 63 slide on the surface of the connecting block 65, and adjusts the sliding position according to the width of the material plate, thereby fixing the material plate to prevent tilting during stamping and bending.

[0024] The second embodiment, as Figure 3-Figure 4 As shown, the forming assembly 6 includes a bottom block 62, which is fixedly connected to the inside of the operating table 5. A positioning hole 68 is provided on the surface of the bottom block 62. The outer surface of the bottom block 62 is frictionally connected with arc-pressing plates 63 on both sides. A connecting block 65 is slidably connected between the opposite surfaces of the arc-pressing plates 63. A middle groove 61 is provided on the surface of the connecting block 65. The material plate is clamped between the arc-pressing plates 63. The arc-pressing plates 63 slide on the surface of the connecting block 65 under the pressure of the outer side. At this time, the arc-pressing plates 63 are clamped on the surface of the material plate from both sides. Since the arc-pressing plates 63 are connected to the external connecting rods 64, the position of the arc-pressing plates 63 is When movement occurs, the outer connecting rod 64 is compressed by the arc plate 63 to retract inward, causing the middle part to bend downward, and the bending angle is affected by the width of the material plate, so that different types of material plates can be fixed, which is convenient for processing, stamping and bending of different types of material plates, and improves the flexibility of the equipment; because the two sides of the plate are restricted by the arc plate 63, the middle part of the material is concave downward when the material plate is stamped. At this time, the V-shaped arc pressure plate 63 is affected by the deformation of the material plate and slides on the surface of the connecting block 65, and the lower part of the arc pressure plate 63 expands outward, so that the bent material plate falls into the bottom block 62, so that the material plate can be taken out after forming.

[0025] External connecting rods 64 are fixedly connected to both sides of the outer surface of the arc pressing plate 63, and connecting shafts 66 are fixedly connected to the surface of the external connecting rods 64. The opposite surfaces of the connecting shafts 66 are rotatably connected to the sliding shafts 67. When the pushing frame 45 drives the card plate 43 to move, the fitting groove 433 fits on the surface of the sliding shaft 67. Since the fitting groove 433 is in the shape of a card slot and the inside is made of elastic material, it can be tightly clamped on the surface of the sliding shaft 67, thereby limiting the position of the card plate 43 after pushing, improving the stability of the stamping and bending equipment, fixing the arc pressing plate 63 during stamping and bending, and preventing the material plate from sliding and deviating during stamping and bending.

[0026] The third embodiment, as Figure 5-Figure 8 As shown, the stabilizing assembly 4 includes a cushion block 41, and the upper surface of the cushion block 41 is threadedly connected with a fixed short rod 42 on both sides, the cushion block 41 is slidably connected to the surface of the external rod 64, the surface of the cushion block 41 is fixedly connected with a fixed seat 47, the outer surface of the fixed seat 47 is rotatably connected with a rotating block 46 on both sides, and the inner surface of the cushion block 41 is rotatably connected with a spring push block 48. After the stamping and bending is completed, the staff rotates the rotating block 46 to make the extension block 414 in the cushion block 41 move the spring piece 481. Since the spring piece 481 is connected to the pushing frame 45, when the spring piece 481 bounces upward and generates friction with the rotating slider 413, the fitting position between the fitting groove 433 and the sliding shaft 67 changes, so that the fitting groove 433 is away from the surface of the sliding shaft 67, and the top rod 44 cancels the pushing of the arc pressing plate 63, so that the arc pressing plate 63 is reset.

[0027] The lower surface of the push block 48 is fixedly connected with a pushing frame 45, and the inner surface of the pushing frame 45 is fixedly connected with a clamping plate 43, which is slidably connected to the surface of the operating table 5. The surface of the pushing frame 45 is penetrated by a push rod 44, and the push rod 44 extends to the surface of the clamping plate 43. The pushing frame 45 is slidably arranged on the surface of the operating table 5. The staff pushes and squeezes from both sides, so that the pushing frame 45 drives the clamping plate 43 to slide toward the surface of the sliding shaft 67, and uses the push rod 44 to squeeze the arc pressing plate 63 during the sliding process, so that the arc pressing plate 63 slides on the surface of the connecting block 65. After being limited by the material plate, the pushing frame 45 stops sliding and clamps the clamping plate 43 on the surface of the sliding shaft 67.

[0028] The pushing frame 45 comprises a slide plate 454 , a slide frame 455 is fixedly connected to the surface of the slide plate 454 , a through hole 452 is formed on the surface of the slide frame 455 , and the through hole 452 is sleeved on the surface of the push rod 44 .

[0029] The surface of the slide 455 close to the slide plate 454 is rotatably connected to the first round rod 451 , and the surface of the slide 455 away from the first round rod 451 is rotatably connected to the second round rod 453 . The first round rod 451 and the second round rod 453 are adapted to the clamping plate 43 .

[0030] The cushion block 41 includes a circular plate 411, a rotating rod 415 is fixedly connected to the inner surface of the circular plate 411, a limiting block 416 is fixedly connected to the surface of the circular plate 411, and extension blocks 414 are arranged on both sides of the outer surface of the limiting block 416, and the extension blocks 414 are fixedly connected to the surface of the rotating block 46. The staff rotates the rotating block 46, and the rotating block 46 is connected to the extension block 414. Since the rotating block 46 rotates upward from bottom to bottom, the extension block 414 is pushed upward, so that the push block 48 is lifted upward by the extension block 414, and the slide plate 454 is connected below the push block 48, so when the push block 48 is lifted upward, it drives the slide plate 454 to move upward.

[0031] The surface of the limiting block 416 away from the rotating rod 415 is fixedly connected with an external groove 412 , and the inner surface of the external groove 412 is slidably connected with a rotating slider 413 , which is adapted to the elastic push block 48 .

[0032] The push block 48 includes a sleeve block 485, which is rotatably connected to the surface of the rotating rod 415, and a spring sheet 481 is fixedly connected to the surface of the sleeve block 485, and bending blocks 482 are frictionally connected to the outer surfaces of the spring sheet 481 on both sides, and an arc sheet 484 is fixedly connected to the surface of the spring sheet 481, and a connecting plate 483 is fixedly connected to the surface of the sliding plate 454. The sleeve block 485 is sleeved on the surface of the rotating rod 415. When the extension block 414 moves the bending block 482, the bending block 482 is pushed and deformed, and drives the spring piece 481 to lift upward, and drives the arc piece 484 and the connecting plate 483 to move upward. Since the arc piece 484 is made of elastic material, the pushing frame 45 will drop the arc piece 484 downward when moving upward, so that the pushing frame 45 is slightly lifted, so that the fitting point between the fitting groove 433 and the sliding shaft 67 is changed, which is convenient for the stabilizing component 4 to reset. After the stamping and bending are completed, the clamping of the material plate is relaxed to facilitate the removal of the material plate.

[0033] The card plate 43 includes an outer plate 432, a fitting groove 433 is provided on the surface of the outer plate 432, a second curved groove 434 is provided on the surface of the outer plate 432 near the fitting groove 433, and the second curved groove 434 is matched with the second round rod 453, and a first curved groove 431 is provided on the surface of the outer plate 432 away from the second curved groove 434, and the first curved groove 431 is matched with the first round rod 451. When the rotating block 46 rotates to drive the pushing frame 45 to be slightly lifted, since the card plate 43 is connected to the surface of the pushing frame 45, the card plate 43 moves upward at this time, the fitting groove 433 slides on the surface of the sliding shaft 67, and the sliding shaft 67 rotates between the connecting shaft 66, the fitting relationship between the fitting groove 433 and the sliding shaft 67 changes, and the pushing force of the top rod 44 on the arc pressing plate 63 changes, so that the arc pressing plate 63 rebounds and resets.

[0034] When in use, the staff places the material sheet on top of the connecting block 65, and then the staff adjusts the position of the pushing frame 45 so that the material sheet is against both sides of the arc pressing plate 63. Since the arc pressing plate 63 is set as a V-shaped structure, the material sheet can be stably clamped between the arc pressing plates 63, and the hydraulic cylinder 2 acts as a transmission to drive the stamping part 8 to punch downward. Before stamping and bending, the staff pushes the pushing frame 45 to make the pushing frame 45 slide on the surface of the operating table 5, so that the pushing frame 45 drives the clamping plate 43 and the forming component 6 to produce extrusion, and the push rod 44 pushes the outer side of the arc pressing plate 63 to make the arc pressing plate 63 slide on the surface of the connecting block 65, and adjusts the sliding position according to the width of the material sheet, so as to fix the material sheet to prevent it from tilting during stamping and bending.

[0035] The material sheet is clamped between the arc pressure plates 63, and the arc pressure plates 63 are pushed from the outside and slide on the surface of the connecting block 65. At this time, the arc pressure plates 63 are clamped on the surface of the material sheet from both sides. Since the arc pressure plates 63 are connected to the external connecting rods 64, when the position of the arc pressure plates 63 moves, the external connecting rods 64 are affected by the inward contraction of the arc pressure plates 63 and bend downward in the middle, and the bending angle is affected by the width of the material sheet, so that different types of material sheets can be fixed, which is convenient for processing, stamping and bending of different types of material sheets, thereby improving the flexibility of the equipment.

[0036] The pushing frame 45 is slidably set on the surface of the operating table 5. The staff pushes and squeezes from both sides, so that the pushing frame 45 drives the card plate 43 to slide toward the surface of the sliding shaft 67, and uses the push rod 44 to squeeze the arc pressing plate 63 during the sliding process, so that the arc pressing plate 63 slides on the surface of the connecting block 65. After being limited by the material plate, the pushing frame 45 stops sliding and clamps the card plate 43 on the surface of the sliding shaft 67.

[0037] When the pushing frame 45 drives the card plate 43 to move, the fitting groove 433 fits on the surface of the sliding shaft 67. Since the fitting groove 433 has a card slot shape and is made of elastic material inside, it can be tightly clamped on the surface of the sliding shaft 67, thereby limiting the position of the card plate 43 after being pushed.

[0038] After the stamping and bending is completed, the staff rotates the rotating block 46, so that the extension block 414 is pushed upward, so that the push block 48 is lifted upward by the extension block 414. The rotating block 46 is connected to the extension block 414. Since the rotating block 46 rotates upward from bottom to bottom, and a slide plate 454 is connected below the push block 48, the slide plate 454 is driven to move upward when the push block 48 is lifted upward, so that the extension block 414 in the cushion block 41 pushes the spring piece 481. Since the spring piece 481 is connected to the pushing frame 45, when the spring piece 481 bounces upward and generates friction with the rotating slider 413, the fitting position between the fitting groove 433 and the sliding shaft 67 changes, so that the fitting groove 433 is away from the surface of the sliding shaft 67, and the push rod 44 cancels the push on the arc pressing plate 63, so that the arc pressing plate 63 is reset.

[0039] When the rotating block 46 rotates and drives the pushing frame 45 to be slightly lifted, since the clamping plate 43 is connected to the surface of the pushing frame 45, the clamping plate 43 moves upward at this time, and the fitting groove 433 slides on the surface of the sliding shaft 67, and the sliding shaft 67 rotates between the connecting shaft 66, and the fitting relationship between the fitting groove 433 and the sliding shaft 67 changes, and the pushing force of the push rod 44 on the arc pressure plate 63 changes, so that the arc pressure plate 63 rebounds and resets.

[0040] The sleeve block 485 is sleeved on the surface of the rotating rod 415. When the extension block 414 moves the bending block 482, the bending block 482 is pushed and deformed, and drives the spring piece 481 to lift upward, and drives the arc piece 484 and the connecting plate 483 to move upward. Since the arc piece 484 is made of elastic material, the pushing frame 45 will drop the arc piece 484 downward when moving upward, so that the pushing frame 45 is slightly lifted, so that the fitting point between the fitting groove 433 and the sliding shaft 67 is changed, which is convenient for the stabilizing component 4 to reset. After the stamping and bending are completed, the clamping of the material plate is relaxed to facilitate the removal of the material plate.
