Description

Technical Field

[0001] This utility model relates to the field of hardware processing equipment technology, specifically a continuous hardware stamping die. Background Technology

[0002] In the field of hardware processing, continuous stamping dies are widely used in the production of small and medium batches of hardware sheets, such as small connectors and gaskets, because they can realize multi-process continuous processing. They are especially suitable for small-scale enterprises with limited investment in automation equipment, such as hardware accessory factories and mechanical parts workshops. Operators usually need to manually cooperate with the dies to complete the loading, positioning and unloading processes. The ease of operation of the unloading process directly affects the overall production efficiency.

[0003] Currently, most mainstream progressive stamping dies use closed or semi-closed grooves for storing workpieces. After stamping, the metal sheet adheres to the inner wall of the groove due to the dimensional adaptability of the stamped part. Furthermore, some parts have slight flanges at the edges. This structure means that operators cannot directly remove the parts with their fingers during unloading; they must use tweezers, flathead screwdrivers, or other tools to carefully pry the workpiece out of the groove. This operation is not only time-consuming but also carries the risk of scratching the workpiece surface or even injuring fingers. Therefore, we need to provide a progressive metal stamping die. Utility Model Content

[0004] The purpose of this utility model is to provide a continuous metal stamping die with a discharge mechanism in the placement slot. After the stamping press presses the metal plate, the stamped metal plate can be easily pushed out. The operator does not need to use tools to pick up the workpiece. He only needs to manually push the pusher block, and the metal plate can be directly pushed out of the placement slot by the sliding of the pusher block. The whole process does not require adjusting the angle or prying the workpiece, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a continuous metal stamping die, comprising:

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5 This utility model provides a technical solution: a continuous metal stamping die, comprising:

[0025] The workbench 1, the tray 2, the placement slot 3 and the stamping device 4 are provided. A column 5 is fixedly installed at the bottom of the tray 2 and is rotatably installed on the top of the workbench 1. Multiple placement slots 3 are opened on the top of the tray 2. The placement slots 3 are used to store hardware plates. The stamping device 4 is installed on the top of the workbench 1 and is used to stamp the hardware plates in the placement slots 3. A material discharge mechanism 6 is provided on one side of the placement slot 3 for stamping.

[0026] The discharge mechanism 6 includes a trough 61, a spring 62 and a pusher block 63. The trough 61 is connected to one side of the placement trough 3. The pusher block 63 is slidably installed in the trough 61. A spring 62 is provided between the pusher block 63 and the trough 61.

[0027] Specifically, a discharge mechanism 6 is provided in the placement groove 3. After the stamping press 4 stamps the metal plate, the stamped metal plate can be easily pushed out. The operator does not need to use tools to pick up the workpiece. He only needs to manually push the pusher block 63. The metal plate can be directly pushed out of the placement groove 3 by the sliding of the pusher block 63. The whole process does not require adjusting the angle or prying the workpiece. The pusher block 63 pushes the discharge to avoid contact friction between the tool and the workpiece surface, which can prevent scratches and deformation on the workpiece surface and ensure the appearance and dimensional accuracy of the stamped parts. At the same time, it eliminates the risk of pricking fingers when the tool is inserted into the groove, improving the safety of operation.

[0028] A slide rod 7 is fixedly installed on one side of the trough 61, and a slide groove 8 is provided in the pusher block 63 to slide with the slide rod 7. A spring 62 is movably sleeved on the surface of the slide rod 7.

[0029] Furthermore, a sliding rod 7 is welded and fixed to the inner wall of the trough 61 facing the placement trough 3, and the axis of the sliding rod 7 is consistent with the length direction of the trough 61; a through-type sliding groove 8 is opened on the pusher block 63 near the bottom of the trough 61, and the inner diameter of the sliding groove 8 is adapted to the outer diameter of the sliding rod 7. The pusher block 63 is sleeved on the surface of the sliding rod 7 through the sliding groove 8 and slides along the length direction of the sliding rod 7; the spring 62 is a cylindrical helical compression spring 62, which is movably sleeved in the area of ​​the sliding rod 7 between the pusher block 63 and the inner wall of the trough 61 on the side away from the placement trough 3. The cooperation between the sliding rod 7 and the sliding groove 8 restricts the sliding direction of the pusher block 63 and prevents the pusher block 63 from deviating and causing the discharge position deviation; the spring 62 automatically resets after the pusher block 63 pushes, without the need for manual adjustment of the position of the pusher block 63.

[0030] A pusher block 9 is fixedly installed on the top of the pusher block 63, and a guard plate 10 is fixedly installed on the surface of the pusher block 9. The guard plate 10 is used to cover the tank 61.

[0031] Specifically, the push block 9 is a rectangular block structure, fixed to the top of the push block 63, and the height of the push block 9 is higher than the depth of the groove 61; the guard plate 10 is an arc-shaped thin plate, one end of which is welded and fixed to the side wall of the push block 9 near the groove 61, and the other end extends to the top of the opening of the groove 61. The width of the guard plate 10 is adapted to the width of the opening of the groove 61, completely covering the opening of the groove 61. The push block 9 increases the hand force application point, avoiding direct contact between the operator's fingers and the slide bar 7 or spring 62 when pushing, thus improving the ease of operation; the guard plate 10 covers the opening of the groove 61 to prevent metal debris generated during the stamping process from falling into the interior of the groove 61.

[0032] It also includes a stop 11 that limits the position of the metal plate in the placement groove 3. The stop 11 includes a circular groove 111, an elastic block 112 and a stop block 113. Circular grooves 111 are provided on both sides of the placement groove 3. The stop block 113 is slidably installed in the circular groove 111. The elastic block 112 is installed between the stop block 113 and the circular groove 111.

[0033] It is worth noting that the circular groove 111 is opened on both sides of the inner wall of the placement groove 3 along the width direction of the placement groove 3, and the opening of the circular groove 111 faces the center of the placement groove 3; the abutment block 113 is a cylindrical structure, one end of which extends into the circular groove 111 and slides with the inner wall of the circular groove 111, and the other end extends out of the circular groove 111; the elastic block 112 is an elastic body structure, which is fixedly embedded between the bottom of the circular groove 111 and the end of the abutment block 113 that extends into the circular groove 111. When the abutment block 113 is squeezed, the elastic block 112 contracts. After the squeezing is released, the elastic block 112 resets and drives the abutment block 113 to extend. Under the action of the elastic block 112, the abutment block 113 always abuts against the side wall of the hardware plate, and works with the placement groove 3 to achieve bidirectional positioning of the hardware plate and prevent the hardware plate from shifting when the disc 2 rotates or is stamped.

[0034] A ball bearing 12 is rotatably mounted on the side of the contact block 113 away from the elastic block 112, and the ball bearing 12 is in contact with the hardware plate.

[0035] It should be noted that the end face of the contact block 113 extending out of the circular groove 111 has a spherical groove, the inner diameter of which is adapted to the outer diameter of the ball 12; the ball 12 is a solid spherical structure, which is embedded in the spherical groove, with part of the ball 12 protruding from the groove and fitting against the side wall of the hardware plate. When the hardware plate moves, the ball 12 rotates around its own axis. The ball 12 converts the sliding friction between the contact block 113 and the hardware plate into rolling friction, reducing the resistance when the hardware plate is placed into the placement slot 3 or pushed out, and avoiding scratches on the surface of the hardware plate due to friction.

[0036] The elastic block 112 is configured as a rubber layer block, which is cylindrical and has multiple holes 13 inside;

[0037] Specifically, the elastic block 112 is a cylindrical adhesive block with multiple evenly distributed circular holes 13 along its axial direction, the holes 13 penetrating both ends of the elastic block 112; one end of the elastic block 112 is bonded to the bottom of the circular groove 111, and the other end is bonded to the end face of the contact block 113. When the contact block 113 is squeezed, the holes 13 shrink, and the elastic block 112 as a whole deforms along the axial direction of the circular groove 111. The elastic block 112 is made of polyurethane elastomer.

[0038] The workbench 1 is equipped with a drive component that drives the column 5 to rotate;

[0039] The driving components include a stepper motor, drive teeth, and a gear ring. The gear ring is fixed to the surface of the column 5 via a key connection. The drive teeth mesh with the internal teeth of the gear ring. The stepper motor is fixed inside the cavity of the worktable 1 via a motor bracket. The motor output shaft is connected to the central shaft of the drive teeth via a coupling. When the stepper motor drives the drive teeth to rotate, it drives the gear ring and the column 5 to rotate synchronously. The stepper motor can precisely control the rotation angle, driving the disc 2 to rotate by a fixed angle each time, so that the placement slot 3 is accurately aligned with the bottom of the stamping press 4, improving the stamping positioning accuracy. The meshing transmission between the gear ring and the drive teeth is stable, preventing slippage when the column 5 rotates, and ensuring the continuity of the continuous stamping process.

[0040] The top of the workbench 1 is provided with a ring-shaped reinforcement 14 that supports the disk body 2;

[0041] Furthermore, the support ring has a circular structure, with its top fitting against the bottom of the disc 2. The inner diameter of the support ring is slightly larger than the outer diameter of the column 5, so as not to affect the rotation of the column 5. Four support plates are evenly distributed radially at the bottom of the support ring. One end of the support plate is slidably installed with the bottom of the support ring, and the other end is fixed to the top surface of the worktable 1. The extension direction of one of the support plates is directly below the stamper 4. The support ring is in full contact with the disc 2, dispersing the weight of the disc 2 and the impact force during stamping, and preventing the disc 2 from deforming due to excessive local stress. The support plate transmits the force of the support ring to the worktable 1, forming a stable support structure and preventing the disc 2 from shaking when rotating.

[0042] The stamping device 4 and the motor in the drive unit involved in this application are both implemented using existing mature technologies and connected to an external PLC controller and power supply. This is a conventional technical means in this field, so the specific circuit connection, control logic and working process will not be described in detail.

[0043] This device has multiple placement slots 3 on the top of the disc body 2. The metal plate to be stamped is placed in the placement slots 3. Due to the setting of the abutment member 11, two balls 12 contact the metal plate. Under the pressure of the metal plate, the abutment block 113 can be driven to slide in the circular groove 111, and the abutment block 113 is pressed to form an auxiliary limit. The drive member can drive the disc body 2 to rotate, rotating the placement slots 3 to below the stamper 4. The lower end of the hydraulic rod in the stamper 4 is equipped with an upper mold, which is placed with the placement slots 113. The lower mold in groove 3 is adapted, and both the lower and upper molds can be removed and replaced by bolts. After the stamping press 4 stamps the metal plate, as the disc 2 rotates, the stamped metal plate rotates and moves away from below the stamping press 4. At this time, the push block 9 can be manually pulled to move the pusher block 63. The pusher block 63 moves in the groove 61 and stretches the spring 62. The end of the pusher block 63 that contacts the metal plate is provided with a rubber layer block. The rubber layer block presses the metal plate and pushes it out. At this time, the ball bearing 12 is in contact with the block. The inner rolling of block 113 results in low friction between the block and the metal plate, protecting the metal plate. Block 113 also compresses the elastic block 112, causing the cylindrical elastic block 112 to deform. The internal hole 13 facilitates easy deformation without affecting the ejection of the metal parts. After the pusher block 63 pushes out the metal plate, the spring 62 pulls the pusher block 63 back, placing the unpressed metal plate into the placement slot 3. The driving components include a stepper motor, drive teeth, and a toothed ring. The toothed ring is fixed to the surface of the column 5, and the surface is meshed with drive teeth. The stepper motor is fixed to the bottom of the worktable 1 to drive the drive teeth to rotate. The bottom of the opening of the placement slot 3 is inclined to facilitate the unloading of the metal plate. The annular reinforcement 14 supports the disc 2. The annular reinforcement 14 includes a support ring and four support plates located at the bottom of the support ring. One of the support plates is located below the punch 4 to provide support. Since the metal plate is relatively thin, the punching force of the punch will not be too large and will not damage the equipment.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
