Description

Technical Field

[0001] This utility model relates to the field of stamping forming equipment technology, and in particular to a multi-directional stamping forming equipment. Background Technology

[0002] A stamping forming device is a mechanical device that uses molds and pressure to apply external force to metal or non-metal sheets, causing them to undergo plastic deformation or separation, thereby obtaining parts or products with the required shape, size and performance. A multi-directional stamping forming device is an advanced stamping equipment that can apply stamping force simultaneously or sequentially, causing multiple metal sheets or blanks to undergo plastic deformation, thereby forming parts with complex geometric structures. To address this, patent CN221848279U discloses a multi-directional bending and flanging integrated forming device, including a base, side plates on both sides of the base, a transmission mechanism on one side of each side plate, a horizontal plate on the top of both side plates, and a stamping mechanism at the bottom of the horizontal plate. The stamping mechanism includes two symmetrically arranged grooves at the bottom of the horizontal plate, each groove containing a horizontal rod. Both ends of the horizontal rod are fixedly connected to the inner wall of the groove. Three sliding blocks are movably sleeved on the outside of each horizontal rod. Hydraulic rods are fixedly mounted at the bottom of each of the three sliding blocks. A connecting plate is shared at the bottom of every two hydraulic rods, and a stamping head is located at the bottom of the connecting plate. This invention enables the simultaneous production of multiple channel steels using multiple stamping heads, thereby effectively improving production efficiency. The multi-directional bending and flanging integrated forming device mentioned above adjusts its position by sliding a sliding block on a crossbar during use. This makes it difficult to achieve precise positioning and can easily cause the stamping head to shift due to the movement of the sliding block, thus affecting the stamping accuracy. Utility Model Content

[0003] The purpose of this invention is to provide a multi-directional stamping forming device to solve the problem that existing multi-directional bending and flanging integrated forming devices are not easy to position.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a multi-directional stamping forming device, including a base; Support rods are fixed at the top edge of the base, and a top plate is fixed at the top of each support rod. A stamping seat is fixed at the top of the base, and a positioning structure is fixed at the top of the top plate. The positioning structure includes a hydraulic push rod fixed to the top of the top plate, a lifting plate installed at the bottom of the hydraulic push rod, a sliding hole provided on the outer side of the support rod inside the lifting plate, a mold core installed at the bottom of the lifting plate, a mold cavity provided at the top of the stamping seat, positioning rods fixed on both sides of the bottom of the lifting plate, springs provided on the outer side of the positioning rods, a slider fixed at the bottom of the springs, and connecting plates fixed on both sides of the stamping seat. Positioning holes are provided inside the connecting plates. The stamping base is equipped with an ejection structure inside.

[0005] Preferably, the lifting plate and the support rod are slidably connected through sliding holes, the mold cores are evenly distributed at the bottom end of the lifting plate, and the mold cavities are evenly distributed at the top end of the stamping seat, with each mold core and mold cavity corresponding to the other.

[0006] The aforementioned structure constrains the movement direction of the lifting plate via the sliding holes during use. This ensures that the lifting plate, driven by the hydraulic push rod, can only move up and down along the axis of the support rod, preventing deviation, swaying, or tilting during lifting. This guarantees smooth and precise lifting action, and allows multiple die cores to simultaneously align and act on the workpieces within their respective cavities when the lifting plate descends. Consequently, multiple workpieces can be stamped simultaneously, improving stamping efficiency and making it suitable for mass production scenarios.

[0007] Preferably, the positioning rods are symmetrically distributed on both sides of the bottom end of the lifting plate, the top end of the spring is fixedly connected to the bottom end of the lifting plate, and the slider is slidably connected to the outside of the positioning rods.

[0008] With the above structure, when the lifting plate moves down to the positioning rod and positioning hole during use, the spring will undergo elastic deformation due to the contact between the slider and the connecting plate. The elasticity of the spring will offset part of the impact force, thereby reducing the wear rate of the components and extending the service life of the device.

[0009] Preferably, the connecting plates are symmetrically distributed on both sides of the stamping seat, the positioning holes correspond one-to-one with the positioning rods, and the positioning rods and connecting plates form a telescopic structure through springs.

[0010] With the above structure, the positioning holes and positioning rods correspond one-to-one during use, ensuring that the positioning rods can be accurately inserted into the corresponding positioning holes during the downward movement of the lifting plate. This further avoids lateral displacement of the lifting plate, ensures the alignment accuracy of the mold core and mold cavity during stamping, and provides a reliable guarantee for the precise forming of multi-directional stamping.

[0011] Preferably, the ejection structure includes an internal cavity disposed inside the stamping seat. A motor is fixed to one side of the internal cavity, and a rotating shaft is fixed to the output end of the motor. Support plates are fixed to both sides of the internal cavity outside the rotating shaft. A worm gear is fixed to the outside of the rotating shaft between the support plates. A threaded rod is installed at the middle position inside the internal cavity. A worm wheel is fixed to the outside of the threaded rod on one side of the worm gear. A limit block is fixed to the top of the threaded rod. A movable plate is installed on the outside of the threaded rod. A threaded hole is provided on the outside of the threaded rod inside the movable plate. An ejector rod is fixed at the edge of the top of the movable plate. An ejector plate is fixed to the top of the ejector rod. A reserved groove is provided at the bottom end of the mold cavity outside the ejector plate.

[0012] Preferably, one end of the rotating shaft passes through one side of the built-in cavity and is rotatably connected to the interior of the stamping seat; the worm gear is meshed with the worm wheel; and the bottom end of the threaded rod passes through the bottom end of the interior of the stamping seat and is fixed with a stop block.

[0013] With the above structure, during use, one end of the rotating shaft passes through one side of the internal cavity and forms a rotatable connection with the interior of the stamping seat, thus providing a stable support point for the rotating shaft. This prevents the shaft from shifting or shaking when driven by the motor, ensuring the stability of power transmission. Furthermore, the bottom end of the threaded rod passes through the bottom of the stamping seat and is fixed with a stop block, which restricts the axial displacement of the threaded rod.

[0014] Preferably, the outer side of the movable plate is fitted into the interior of the built-in cavity, the movable plate and the threaded rod are connected by a threaded hole, the ejector rods are evenly distributed at the top of the movable plate, the ejector rods correspond one-to-one with the mold cavity, the top of the ejector rods penetrates the interior of the stamping seat and extends into the interior of the mold cavity and is fixedly connected to the bottom of the ejector plate, and the outer side of the ejector plate is fitted into the interior of the reserved groove.

[0015] With the above structure, the outer side of the moving plate fits into the inside of the inner cavity during use, which can constrain the moving direction of the moving plate, so that it can only move smoothly up and down along the inner wall of the inner cavity. When the moving plate moves up, multiple ejector plates can simultaneously eject the molded workpieces in multiple mold cavities, which greatly improves the efficiency of picking up parts in mass production.

[0016] The multi-directional stamping forming device provided by this utility model has the following advantages: With a positioning structure, the lifting plate is moved down steadily by activating the hydraulic push rod. Combined with the one-to-one correspondence between the mold core and the mold cavity, it can simultaneously perform stamping operations on multiple workpieces or different positions of the same workpiece, reducing the time interval between single stamping operations and greatly improving the overall stamping efficiency. It is suitable for mass production scenarios. In addition, during the cooperation between the positioning rod and the connecting plate, the buffering effect of the spring can reduce the impact and vibration during the stamping process, making the device operate more smoothly. By incorporating an ejection structure, the ejector rod and ejector plate are automatically ejected via a motor, eliminating the need for manual removal of the molded workpiece from the mold cavity. This avoids potential damage to the workpiece or hand injuries that could result from manual removal, thus improving the convenience and reliability of the removal process.

[0019] 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.

[0020] Please see Figure 1-5 The present invention provides a multi-directional stamping forming device, including a base 1.

[0021] Reference Figures 1-3As shown, support rods 2 are fixed at the edge of the top of the base 1, and a top plate 3 is fixed at the top of the support rods 2. A stamping seat 4 is fixed at the top of the base 1, and a positioning structure 5 is fixed at the top of the top plate 3. The positioning structure 5 includes a hydraulic push rod 501 fixed to the top of the top plate 3. A lifting plate 502 is installed at the bottom of the hydraulic push rod 501. A sliding hole 503 is provided on the outside of the support rod 2 inside the lifting plate 502. A mold core 504 is installed at the bottom of the lifting plate 502. A mold cavity 505 is provided at the top of the stamping seat 4. Positioning rods 506 are fixed on both sides of the bottom of the lifting plate 502. A spring 507 is provided on the outside of the positioning rod 506. A slider 508 is fixed at the bottom of the spring 507. Connecting plates 5 are fixed on both sides of the stamping seat 4. 09. The connecting plate 509 has a positioning hole 510 inside. The lifting plate 502 and the support rod 2 are slidably connected through the sliding hole 503. The mold cores 504 are evenly distributed at the bottom of the lifting plate 502. The mold cavities 505 are evenly distributed at the top of the stamping seat 4. The mold cores 504 and the mold cavities 505 correspond one-to-one. The positioning rods 506 are symmetrically distributed on both sides of the bottom of the lifting plate 502. The top of the spring 507 is fixedly connected to the bottom of the lifting plate 502. The slider 508 is slidably connected to the outside of the positioning rods 506. The connecting plate 509 is symmetrically distributed on both sides of the stamping seat 4. The positioning hole 510 corresponds one-to-one with the positioning rod 506. The positioning rod 506 and the connecting plate 509 are telescopically connected through the spring 507.

[0022] By activating the hydraulic push rod 501, the lifting plate 502 moves downward along the support rod 2. The lifting plate 502 is slidably connected to the support rod 2 through the sliding hole 503 on the outer side of the inner support rod 2, ensuring the stable lifting and lowering of the lifting plate 502. During the downward movement of the lifting plate 502, the mold core 504 performs a stamping operation on the workpiece placed in the mold cavity 505. At the same time, the positioning rods 506 symmetrically distributed on both sides of the bottom end of the lifting plate 502 cooperate with the positioning holes 510 in the connecting plates 509 symmetrically distributed on both sides of the stamping seat 4 to ensure the precise positioning of the lifting plate 502 during downward movement, ensuring stamping accuracy and achieving multi-directional precision stamping. Under the action of the spring 507, the elastic characteristics of the spring 507 can play a certain buffering role, reducing the rigid collision between the positioning rods 506 and the connecting plates 509, reducing component wear, and extending the service life of the device.

[0023] Reference Figures 3-5As shown, the stamping base 4 is internally equipped with an ejector structure 6. The ejector structure 6 includes an internal cavity 601 inside the stamping base 4. A motor 602 is fixed to one side inside the internal cavity 601. A rotating shaft 603 is fixed to the output end of the motor 602. Support plates 604 are fixed to both sides of the internal cavity 601 outside the rotating shaft 603. A worm gear 605 is fixed to the outside of the rotating shaft 603 between the support plates 604. A threaded rod 606 is installed at the middle position inside the internal cavity 601. A worm wheel 607 is fixed to the outside of the threaded rod 606 on one side of the worm gear 605. A limit block 608 is fixed to the top of the threaded rod 606. A moving plate 609 is installed to the outside of the threaded rod 606 inside the moving plate 609. A threaded hole 610 is provided on the outside of the threaded rod 606 inside the moving plate 609. Ejector rods 611 are fixed at the edge of the top of the moving plate 609. An ejector plate 612 is fixed at the top of the mold. A pre-reserved groove 613 is provided at the bottom of the outer mold cavity 505 of the ejector plate 612. One end of the rotating shaft 603 passes through one side of the inner cavity 601 and is rotatably connected to the inside of the stamping seat 4. The worm 605 is meshed with the worm wheel 607. The bottom end of the threaded rod 606 passes through the bottom of the inside of the stamping seat 4 and is fixed with a stop block. The outer side of the moving plate 609 is fitted into the inside of the inner cavity 601. The moving plate 609 and the threaded rod 606 are threadedly connected through the threaded hole 610. The ejector rods 611 are evenly distributed at the top of the moving plate 609. The ejector rods 611 correspond one-to-one with the mold cavity 505. The top end of the ejector rod 611 passes through the inside of the stamping seat 4 and extends into the inside of the mold cavity 505 and is fixedly connected to the bottom of the ejector plate 612. The outer side of the ejector plate 612 is fitted into the inside of the pre-reserved groove 613.

[0024] After stamping, the formed workpiece needs to be removed from the mold cavity 505. The motor 602 is started to drive the rotating shaft 603 to rotate, which in turn drives the worm gear 605 to rotate. The worm gear 605 meshes with the worm wheel 607. The rotation of the worm gear 605 drives the worm wheel 607 to rotate, thereby rotating the threaded rod 606 connected to the worm wheel 607. The rotation of the threaded rod 606 causes the moving plate 609 to move upward under the action of the threaded hole 610. This causes the ejector rod 611 at the top of the moving plate 609 to move upward along with the moving plate 609, causing the ejector plate 612 to move upward within the reserved slot 613, ejecting the formed workpiece from the mold cavity 505, completing the entire stamping and removal process.

[0025] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
