Description

Technical Field

[0001] This invention relates to the field of stamping die technology, specifically to a metal stamping die. Background Technology

[0002] Metal stamping dies are process equipment that uses molds and presses to apply pressure to metal sheets and strips, causing them to undergo plastic deformation or separation, thereby obtaining parts of the desired shape and size. Their core function is to achieve efficient, high-precision, and high-volume production of metal parts. Application areas include: Automotive: engine seals, bearing housings, wheel hub trim parts; Electronics: battery casings, heat sinks, connector terminals; Packaging: metal bottle caps, food can lids; Hardware: gaskets, badges, lock components; Medical; Aerospace: implant parts, aircraft seals, etc.

[0003] Metal stamping is a common processing method in the production of workpieces and accessories. It usually uses special molds to limit the workpieces and then uses hydraulic equipment to stamp them into shape. Metal stamping dies are often used in this process to ensure the stamping operation. When producing round and sheet metal workpieces, metal stamping dies usually need to stamp accessories of different sizes. However, existing metal stamping dies cannot be adjusted in size as needed, and the force and height of springback after stamping are usually not adjustable. Therefore, it is necessary to open and design dies of various sizes and specifications, which increases the cost and reduces the efficiency due to the cumbersome replacement process. Based on this, a metal stamping die is proposed. Summary of the Invention

The specifications and dimensions of the outer forming mold and the mounting base three are adapted to the specifications and dimensions of the lower mold base assembly and the upper mold base assembly.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. When the mold is in use, the operator installs the lower template and base mechanism on the installation position of the stamping equipment with bolts, and installs the movable mounting seat and hydraulic end mounting mechanism on the support surface and hydraulic output end of the stamping equipment. Before operation, the mold to be used is adjusted. Then, during stamping, the metal panel is placed on the opposite side of the lower mold base mechanism and the upper mold base mechanism, and stamping is performed by hydraulic extension. After stamping, the upper mold base mechanism retracts and separates from the lower mold base mechanism. At this time, the metal plate is formed. The spring recovery effect of the spring mechanism lifts the lower mold base mechanism, thereby demolding the metal panel when it needs to be stamped, so that the operator can take it out and transfer it for the next stamping forming operation. The overall use effect is good, it is easy to adjust, and it can adapt to different stamping operation needs. The spring position can be changed, thereby increasing the multiple use effects of the structure.

[0017] 2. The main body of the lower die base mechanism is a circular shape composed of multiple lower die base components that are precision machined and closely arranged. During adjustment, the outer and inner layers are separated, allowing adjustment of the different heights of multiple lower die base components to change the circular size for stamping. Furthermore, when a single lower die base component is raised or lowered relative to the entire lower die base assembly, it can perform punching or groove stretching, thus adapting to various workpiece operations. A single adjustment can be used to perform stamping operations in conjunction with the production process, facilitating equipment and production and further enhancing the usability.

[0018] 3. The springback mechanism lifts and demolds the metal sheet after stamping. Rotating the limit adjustment bolt changes the threaded connection position of the limit adjustment bolt relative to the nut fixing part, thereby changing the limiting position of one end of the limit adjustment bolt against the sealing piston. As the sealing piston moves backward, the movement space of the hydraulic oil in the springback mechanism's connecting pipe expands. Consequently, the hydraulic oil lifting position of the hydraulic piston head and the inside of the hydraulic piston cylinder will decrease due to insufficient pressure, thus adjusting the lifting height of the lower mold base assembly. This facilitates adjustment. When combined with the height adjustment of the lower mold base assembly, various lifting effects can be combined, making it easy to adjust the lifting and demolding height and increasing the effectiveness of auxiliary operations.

Detailed Implementation

[0031] 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.

[0032] Please see Figures 1-11 This invention provides a technical solution: a metal stamping die, including a lower template 1 and an outer module 10. The lower template 1 has several mounting slots 101 and several mounting holes 102. Several support columns 2 are fixedly installed on the top of the lower template 1. Each support column 2 has a movable mounting seat 201 installed through bolts on its top. An upper template 3 is slidably sleeved on the outside of the support columns 2. The upper template 3 has several mounting holes 301. An upper die base mechanism 9 is installed on the bottom of the upper template 3 through bolts. Several upper die adjustment groups 4 are movably arranged on the top of the upper die base mechanism 9. A lower die base mechanism 6 is installed on the top of the lower template 1 through bolts. A base mechanism 7 is arranged on the bottom of the lower template 1. A springback mechanism 8 is movably installed inside the base mechanism 7.

[0033] The lower mold base mechanism 6 includes a mounting base 601. A limiting guide seat 602 is fixedly installed on the inner side of the mounting base 601. A limiting ring seat 605 is movably sleeved on the inner side of the limiting guide seat 602. Several lower mold base assemblies 603 are movably installed on the inner side of the limiting ring seat 605. A metal sealing plate 604 is movably sleeved on the inner surface of the top surface of the lower mold base assembly 603 through a groove. A movable sleeve 606 is movably sleeved on the top of the inner cavity of the lower mold base assembly 603. A lower bolt hole 608 is opened through the movable sleeve 606 and the top of the lower mold base assembly 603. A mounting bolt 613 is threadedly connected inside the lower bolt hole 608.

[0034] The working principle of the above technical solution is as follows: During use, the operator installs the lower template 1 and the base mechanism 7 at the mounting location of the stamping equipment using bolts, and installs the movable mounting base 201 and the hydraulic end mounting mechanism 5 on the support surface and hydraulic output end of the stamping equipment. Before operation, the required mold is adjusted. Then, during stamping, the metal panel is placed on the opposite side of the lower mold base mechanism 6 and the upper mold base mechanism 9, and stamping is performed by hydraulic extension. After stamping, the upper mold base mechanism 9 retracts and separates from the lower mold base mechanism 6. At this time, the metal plate is formed, and the elastic recovery effect of the spring mechanism 8 lifts the lower mold base mechanism 6, thereby demolding the metal panel when it needs to be stamped, so that the operator can take it out and transfer it for the next stamping forming operation. The overall use effect is good, it is easy to adjust, and it can adapt to different stamping operation needs. The spring position can be changed, thereby increasing the multiple uses of the structure.

[0035] In another implementation scheme, such as Figures 1-9 As shown, the lower mold base assembly 603 is arranged in a ring array, uniformly arranged in a circular shape around the central area of ​​the mold. Its shape is a fan ring with a circular center. Each fan ring structure is arranged in an orderly manner along the outer circumference of the circular ring, together forming the ring functional area of ​​the mold.

[0036] The main body of the lower die holder mechanism 6 is a circular shape composed of multiple lower die holder components 603 that are precisely machined by a machine tool and then tightly arranged and seamlessly joined. The size of this circular shape can be configured in multiple specifications according to the different workpieces to be processed, making it convenient to adapt to stamping of products of various sizes. During adjustment, the outer and inner layers are separated, allowing adjustment of the different heights of multiple lower die holder components 603 to change the circular size for suitability for stamping. Furthermore, when a single lower die holder component 603 is raised or lowered relative to the entire assembly of lower die holder components 603, it can perform punching or groove stretching, thus adapting to various workpiece operations. A single adjustment can be coordinated with the production process for stamping operations, facilitating equipment and production, and further enhancing the effectiveness of use.

[0037] In another implementation scheme, such as Figures 1-9 As shown, mounting base 601 is fixed to the top of the lower template 1 by bolts passing through mounting slot 102, and the bottom of metal sealing plate 604 is fixedly installed with the top of mounting bolt 613.

[0038] Mounting base 601 is installed on top of mounting slot 102 to fix and limit the position of the base of the lower die holder mechanism 6 for local adjustment. Metal sealing plate 604 is fixed to mounting bolt 613, facilitating a tight seal between the metal sealing plate 604 and the slot at the top of the lower die holder assembly 603. The metal sealing plate 604 and the slot of the lower die holder assembly 603 are machined seamlessly to avoid impact on the sheet metal during stamping. Furthermore, the fixed installation of the metal sealing plate 604 and mounting bolt 613 facilitates... The metal sealing plate 604 is fixedly positioned in the groove at the top of the lower mold base assembly 603 by the threaded connection of the mounting bolt 613, thus ensuring a stable connection and preventing it from falling off. When it is necessary to disassemble or assemble the metal sealing plate 604 and the mounting bolt 613, simply use a strong magnet such as a neodymium magnet to adhere to the top of the metal sealing plate 604, and gradually and slowly rotate the metal sealing plate 604 to drive the mounting bolt 613 to rotate, thereby disengaging the mounting bolt 613 from the lower bolt hole 608, thus achieving the disassembly and assembly effect, which is convenient for cooperative operations.

[0039] In another implementation scheme, such as Figures 1-9As shown, the inner side of the movable sleeve 606 is movably fitted with a limiting movable ring 607 via an adapter slot. A lower adjusting bolt 609 is fixedly fitted on the inner side of the limiting movable ring 607. The lower adjusting bolt 609 movably passes through the movable sleeve 606 and extends to the outer side of the movable sleeve 606. An adjusting screw 610 is threadedly fitted on the outer side of the lower adjusting bolt 609. The adjusting screw 610 movably passes through the lower template 1 and the mounting base 601 and extends to the inner side of the base mechanism 7. Several limiting anti-loosening nuts 611 are connected to the outer thread at the bottom end of the lower adjusting bolt 609. A fixed adjusting nut 612 is fixedly installed at the bottom of the lower adjusting bolt 609.

[0040] When adjusting the components of the lower mold base mechanism 6, the position of the lower mold base assembly 603 needs to be adjusted. Rotating the limiting anti-loosening nut 611 releases the limiting on the lower adjusting bolt 609. Rotating the fixing adjusting nut 612 then drives the threaded connection between the lower adjusting bolt 609 and the adjusting screw cylinder 610. The adjusting screw cylinder 610 is stabilized under the limiting position of the limiting movable plate 704. The lower adjusting bolt 609 rotates and engages with the movable sleeve 606 through the limiting movable ring 607, thus pulling the movable sleeve 606. The movable sleeve 606 and the outer shell of the lower mold base assembly 603 are stabilized through the threaded connection between the mounting bolt 613 and the lower bolt hole 608. This allows the movable sleeve 606 to maintain its position. The displacement of the lower die base assembly 603 is changed, thereby adjusting the height position of the lower die base assembly 603. After the adjustment is completed, the limit anti-loosening nut 611 and the lower adjusting bolt 609 are rotated to release the thread position limit at the bottom. Then, the limit is set by double nuts or multiple nuts and anti-loosening nuts to reduce loosening and extend the stamping time so that different lower die base assemblies 603 can be adjusted point by point. If the lower die base assemblies 603 are to be gradually unified, a flat metal panel needs to be laid on the top of the lower die base assembly 603 to facilitate the adjustment and positioning of the bottom bolts. Scale lines can be coated on the outside of the lower adjusting bolt 609 and the adjusting screw 610 to make it easy for operators to observe the adjustment position and adjust the height.

[0041] In another implementation scheme, such as Figures 1-4 , Figure 10 and Figure 11As shown, the base mechanism 7 includes a lower mounting frame 701, which is fixedly mounted on the bottom of the lower template 1. A limiting movable plate 704 is movably sleeved on the inner side of the lower mounting frame 701. An adjusting screw 610 is fixedly sleeved inside the limiting movable plate 704. A disassembly and assembly limiting plate 705 is movably sleeved on the inner side of the bottom end of the lower mounting frame 701. Several fixing bolts 702 are threaded through the internal threads of the disassembly and assembly limiting plate 705. The fixing bolts 702 are threaded and extend to the outer side of the lower mounting frame 701. The fixing bolts 702 are circumferentially distributed on the outer side of the disassembly and assembly limiting plate 705 and the lower mounting frame 701. A fixed base plate 703 is movably mounted on the bottom of the lower mounting frame 701. Several support columns 706 are fixedly mounted on the top of the fixed base plate 703. The top of the support columns 706 is in movable contact with the bottom of the disassembly and assembly limiting plate 705. The specifications and dimensions of the support columns 706 and the lower mounting frame 701 are adapted to the specifications and dimensions of the lower template 1.

[0042] During adjustment, the base mechanism 7 provides support and stable installation for the internal structure. For example, the limiting movable plate 704 fixes and limits the lower adjusting bolt 609, while the movable sleeve itself is limited inside the limiting movable plate 704. The top mounting seat 806 provides fixed support for the spring mechanism 8, and the spring mechanism 8 is bolted to the disassembly and assembly limiting plate 705. The disassembly and assembly limiting plate 705 itself is fixed by the fixing bolt 702, which facilitates the disassembly and assembly of the structure and the adjustment of its position, making it convenient for subsequent maintenance and position adjustment. The fixed base plate 703 and the support column 706 are bolted to the support surface to support the bottom of the disassembly and assembly limiting plate 705, thereby increasing the support effect of the structure and providing structural support for the position of the spring mechanism 8, ensuring the stability of the structure.

[0043] In another implementation scheme, such as Figures 1-11As shown, the rebound mechanism 8 includes several hydraulic piston cylinders 804. Each hydraulic piston cylinder 804 is movably sleeved inside the disassembly / removal limiting plate 705. A bottom mounting ring seat 807 is fixedly installed at the bottom of each hydraulic piston cylinder 804, and the bottom mounting ring seat 807 is fixedly installed at the bottom of the disassembly / removal limiting plate 705 by bolts. A hydraulic piston head 805 is movably and sealingly sleeved inside the hydraulic piston cylinder 804. A top mounting seat 806 is fixedly installed at the top of the hydraulic piston head 805. The top mounting seat 806... The hydraulic piston cylinder 804 is bolted to the bottom of the limiting movable plate 704. The top mounting seat 806 is sized to match the hydraulic piston cylinder 804. The hydraulic piston cylinders 804 are evenly distributed circumferentially on opposite sides of the limiting movable plate 704 and the disassembly limiting plate 705, and are located circumferentially outside the limiting ring seat 605. The bottom end of the hydraulic piston cylinder 804 is connected to a hydraulic oil transmission pipe 808, which extends movably through to the disassembly limiting plate 705. At the bottom, the opposite end of the hydraulic oil transmission pipe 808 is connected to a pressure equalizing hollow disc 809. The bottom end of the pressure equalizing hollow disc 809 is connected to a connecting pipe 801. The connecting pipe 801 extends movably to the bottom of the fixed base plate 703. Two sealing pistons 811 are movably sleeved on the inner side of the connecting pipe 801. A return spring 812 is fixedly installed on the opposite side of the two sealing pistons 811. The return spring 812 is movably sleeved inside the connecting pipe 801. The connecting pipe 801 and the pressure equalizing... Hydraulic oil is installed inside the hollow disc 809, the hydraulic oil transmission pipe 808, and the hydraulic piston cylinder 804. A nut fixing device 802 is fixedly installed at the end of the connecting pipe 801 away from the pressure equalizing hollow disc 809. A limit adjusting bolt 803 is threaded on the inner side of the nut fixing device 802. A hexagonal groove 810 is opened inside the limit adjusting bolt 803. The end of the limit adjusting bolt 803 away from the hexagonal groove 810 is movably connected to one side of the sealing piston 811.

[0044] After the lower die holder mechanism 6 completes the stamping, the upper die holder mechanism 9 and the lower die holder mechanism 6 disengage, releasing the limiting pressure. At this time, the return spring 812 returns to its original compressed state. Since one side of the sealing piston 811 is stably supported by the limiting adjusting bolt 803 and the nut fixing mounting part 802, the elastic force of the return spring 812 can only be transmitted through the sealing piston 811 at the other end. At this time, the sealing piston 811 moves and pushes the hydraulic oil inside the connecting pipe 801 to move. The hydraulic oil is equalized by the pressure equalizing hollow plate 809 and enters the hydraulic oil transmission pipe 808. Then, it is transmitted to the hydraulic piston cylinder 804 through the hydraulic oil transmission pipe 808, thereby lifting the hydraulic piston head 805 through the hydraulic oil. The top of the hydraulic piston head 805 lifts the limiting movable plate 704. Since the limiting movable plate 704 is movably sleeved inside the lower mounting frame 701 and is connected to the adjusting screw cylinder The 610 fixed sleeve then transmits the lifting force to the lower mold base assembly 603, thereby achieving the function of lifting and demolding the metal sheet after stamping. Rotating the limit adjustment bolt 803 changes the threaded connection position of the limit adjustment bolt 803 relative to the nut fixing mounting part 802, thereby changing the position of the sealing piston 811 by one end of the limit adjustment bolt 803. As the sealing piston 811 moves backward, the movement space of the hydraulic oil in the connecting pipe of the spring mechanism 8 expands. Consequently, the lifting position of the hydraulic oil inside the hydraulic piston head 805 and the hydraulic piston cylinder 804 will decrease due to insufficient pressure, thereby adjusting the lifting height of the lower mold base assembly 603 for easy adjustment. If combined with the height adjustment of the lower mold base assembly 603, various lifting height effects can be combined to facilitate the adjustment of the lifting and demolding height, increasing the effect of auxiliary operation.

[0045] In another implementation scheme, such as Figures 1-9As shown, the upper mold base mechanism 9 includes a second limiting ring seat 904, which is fixed to the bottom of the upper template 3 by bolts passing through the mounting slot 301. A threaded strip 903 is provided on the outer side of the second limiting ring seat 904, and an upper cutting ring 901 is threadedly sleeved onto the outer side of the second limiting ring seat 904 via the threaded strip 903. Several upper mold base assemblies 905 are movably mounted on the inner side of the second limiting ring seat 904. A through slot is provided inside each upper mold base assembly 905, and an upper bolt hole 907 is provided at the bottom of each upper mold base assembly 905. A mounting bolt 90 is threadedly connected inside the upper bolt hole 907. 8. A metal sealing plate 2 906 is fixedly installed at the bottom of the mounting bolt 3 908. The metal sealing plate 2 906 is movably sleeved on the inner side of the bottom end of the upper mold base assembly 905 through a groove. A limiting rubber post 902 is movably installed on the top of the upper cutting ring 901. The limiting rubber post 902 is distributed in a circle on the opposite side of the upper cutting ring 901 and the upper template 3. The upper mold base assembly 905 is arranged in a ring array, evenly arranged in a circle around the central area of ​​the mold. Its shape is a fan ring with a circular center. Each fan ring structure is arranged in an orderly manner along the outer circumference of the circular ring, together forming the ring functional area of ​​the mold.

[0046] The upper die base mechanism 9 has a similar function and shape to the lower die base mechanism 6, and the same specifications and dimensions. The only difference is the adjustment and installation methods. It adds two convenient adjustment functions. When trimming the metal round plate, the threaded connection between the upper cutting ring 901 and the threaded strip 903 is rotated to change the position of the second limiting ring seat 904. The corresponding size limiting rubber post 902 is inserted into the gap between the upper template 3 and the upper cutting ring 901 to assist in stabilization. This causes the upper cutting ring 901 to protrude a few threads from the bottom of the upper die base assembly 905, which is convenient for stamping and cutting off the excess edge during stamping. The limiting guide seat 602 supports the bending and cutting after the limit is cut. The positions of the first limiting ring seat 605 and the second limiting ring seat 904 correspond to each other, which plays a role in limiting and stabilizing, and also plays a role in trimming and removing the edges. The position can be adjusted according to the process during stamping to facilitate stability.

[0047] In another implementation scheme, such as Figures 1-9 As shown, the hydraulic end mounting mechanism 5 includes a mounting bridge 501. Mounting bases 502 are fixedly mounted on the bottom of both ends of the mounting bridge 501. The mounting bases 502 are fixedly mounted on the top of the upper template 3 by bolts. A hydraulic cylinder mounting seat 503 is fixedly mounted in the middle of the top surface of the mounting bridge 501.

[0048] The mounting cable tray 501 and mounting base 502 are connected to the top of the upper template 3, and connected to the output end of the hydraulic cylinder through the hydraulic cylinder mounting seat 503, so that the hydraulic end can extend and drive the hydraulic end mounting mechanism 5 to move down, thereby driving the upper template 3 to move down, so as to facilitate the connection of the hydraulic telescopic position.

[0049] In another implementation scheme, such as Figures 1-9 As shown, the upper mold adjustment group 4 includes an upper adjustment bolt 401. A limiting ring 405 is fixedly sleeved on the outer side of the bottom end of the upper adjustment bolt 401. The limiting ring 405 and the upper adjustment bolt 401 are rotatably sleeved on the inner side of the upper mold base assembly 905 through a through groove. A fixed adjustment nut 403 is threadedly connected to the outer side of the upper adjustment bolt 401. The fixed adjustment nut 403 is fixedly installed on the top of the upper template 3. The outer side of the upper adjustment bolt 401 is threadedly connected to the inner side of the upper template 3. Several limiting anti-disengagement nuts 402 are threadedly sleeved on the outer side of the top end of the upper adjustment bolt 401. A hexagonal groove 404 is opened on the top of the upper adjustment bolt 401.

[0050] If the upper mold base assembly 905 is adjusted to match the position of the lower mold base assembly 603, then the threaded connection of the limit anti-loosening nut 402 on the outside of the upper adjusting bolt 401 is rotated. The limit anti-loosening nut 402 releases the anti-loosening limit on the fixed adjusting nut 403. Then, by inserting a hexagonal wrench into the hexagonal slot 404, the upper adjusting bolt 401 is rotated. Under the action of the threaded connection between the upper adjusting bolt 401 and the fixed adjusting nut 403 and the threaded connection between the upper mold plate 3, the position of the upper adjusting bolt 401 is changed. The upper adjusting bolt 401 and the limit movable ring... 405 rotates and is limited inside the upper mold base assembly 905 through the through slot, thereby changing the support position of the upper mold base assembly 905. Due to the precise and seamless structure of the upper mold base assemblies 905, multiple upper mold base assemblies 905 are limited, so the rotation of the upper adjusting bolt 401 only affects the upper mold base assembly 905 by changing its position and height. When the height of the upper mold base assembly 905 changes, the limiting anti-loosening nut 402 is rotated again to squeeze and limit the adjusting nut 403 to prevent it from being dislodged, thereby changing the adjustment position of the upper mold base assembly 905.

[0051] In another implementation scheme, such as Figures 1-9 As shown, the external module 10 includes an outer forming mold 1001, a mounting base 3 1002, and a printing mold 1003. The printing mold 1003 is movably sleeved inside the outer forming mold 1001. The outer forming mold 1001 is fixedly installed on the top of the mounting base 3 1002. The mounting base 3 1002 has several mounting bolt holes 1004 inside. The specifications and dimensions of the mounting bolt holes 1004 are adapted to the specifications and dimensions of the upper bolt hole 907 and the lower bolt hole 608. The specifications and dimensions of the outer forming mold 1001 and the mounting base 3 1002 are adapted to the specifications and dimensions of the lower mold base assembly 603 and the upper mold base assembly 905.

[0052] When additional stamping dies are required, neodymium magnet strong magnetic wrenches are used to attach metal sealing plates 906 and 604 respectively. After inserting metal sealing plates 906 and 604, the corresponding external die assembly 10 is connected by inserting bolts into the upper bolt hole 907 and lower bolt hole 608 through the mounting bolt hole 1004, thus fixing the connection position. This facilitates the addition of additional small dies to the outside of the lower die base mechanism 6 and the upper die base mechanism 9 for position adjustment, allowing for simultaneous completion of stamping and printing processes. This reduces additional processing time, enhances the overall usability of the structure, and improves the overall usability of the structure. The dimensions of the multiple external dies 10 are adapted to the multi-layered adjustable annular dies of the lower die base assembly 603 and the upper die base assembly 905, facilitating different uses and further enhancing the overall usability of the structure.

[0053] Although embodiments of the 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 invention, the scope of which is defined by the appended claims and their equivalents.
