Before the operation, the mold to be used is adjusted, and then the metal panel is placed on the opposite sides of the lower die seat mechanism and the upper die seat mechanism during stamping, and the stamping is performed by hydraulic extension. After the stamping is completed, the upper die seat mechanism retracts and separates from the lower die seat mechanism.

[0018] 3. The rebound mechanism is set up to lift and demould the metal sheet after stamping, and rotating the limit adjustment bolt will change the threaded connection position of the limit adjustment bolt relative to the nut fixing mounting part, thereby changing the limit position of the sealing piston squeezed by one end of the limit adjustment bolt. As the sealing piston moves backward, the movement space of the hydraulic oil in the pipeline connected to the rebound mechanism is expanded, and then the hydraulic oil lifting position on the hydraulic piston head and the inner side of the hydraulic piston cylinder is insufficient due to insufficient pressure, which will reduce the lifting height, thereby adjusting the lifting height of the lower die base assembly, which is convenient for adjustment. For example, in conjunction with the height adjustment of the lower die base assembly, a variety of height lifting effects can be combined, which is convenient for adjusting the height of lifting and demoulding, and increases the effect of auxiliary operation.

[0033] The lower die base mechanism 6 includes a mounting base 601, on the inner side of which a limiting guide base 602 is fixedly mounted, on which the limiting guide base 602 is movably sleeved, on the inner side of which a limiting ring base 605 is movably mounted, on the inner side of which a plurality of lower die base assemblies 603 are tightly fitted and movably mounted, a metal sealing plate 604 is movably sleeved through a groove on the top surface of the lower die base assembly 603, on the top of the inner cavity of the lower die base assembly 603 a movable sleeve base 606 is movably sleeved, a lower bolt hole 608 is formed through the movable sleeve base 606 and the top of the lower die base assembly 603, and the inner thread of the lower bolt hole 608 is connected with a mounting bolt 613.

[0034] The working principle of the above technical solution is as follows: when in use, the operator installs the lower template 1 and the base mechanism 7 at the installation position of the stamping equipment through bolts, and installs the movable mounting seat 201 and the hydraulic end mounting mechanism 5 on the support surface and hydraulic output end of the stamping equipment. The required mold is adjusted before the operation. Then, the metal panel is placed on the opposite sides of the lower die seat mechanism 6 and the upper die seat mechanism 9 during stamping, and stamped by hydraulic extension. After the stamping is completed, the upper die seat mechanism 9 retracts and disengages from the lower die seat mechanism 6. At this time, the metal plate is formed, and the elastic recovery effect of the rebound mechanism 8 lifts up the lower die seat mechanism 6, so that the metal panel needs to be demolded when stamping, so that the operator can take it out and transfer it for the next stamping and forming operation process. The overall use effect is good, it is easy to adjust, and can adapt to different stamping operation needs. The rebound position can be changed, thereby increasing the various use effects of the structure.

[0035] In another embodiment, Figure 1-Figure 9 As shown, the lower mold base assembly 603 is distributed in a ring array and is evenly arranged in a circle around the center area of ​​the mold. Its shape is fan-shaped with a circular ring at the center. The fan-shaped structures are arranged in an orderly manner along the outer circumference of the circular ring, together forming an annular functional area of ​​the mold.

[0036] The main part of the lower die base mechanism 6 is a circular shape formed by a plurality of lower die base components 603 which are closely arranged and fit seamlessly after being processed by a precision machine tool, and the size of the circular shape is set in multiple specifications according to the different production of the workpieces to be processed, so as to facilitate the stamping of products of various specifications and sizes, and the outer and inner layers are separated during adjustment, so that the different heights of the plurality of lower die base components 603 can be adjusted to change the circular size for adaptive stamping, and when a single lower die base component 603 is lifted or lowered from the entire lower die base component 603 assembly, punching or groove stretching can be performed, so as to adapt to various workpiece operations, and one-time adjustment can be carried out in coordination with the production process for stamping operations, so as to facilitate coordination with equipment and production, and further increase the use effect.

[0037] In another embodiment, Figure 1-Figure 9 As shown, the mounting seat 1 601 is fixed to the top of the lower template 1 by bolts passing through the mounting slot 102 , and the bottom of the metal sealing plate 1 604 is fixedly installed with the top of the mounting bolt 2 613 .

[0038] The mounting seat 601 is installed on the top of the mounting slot hole 102 to fix and limit and partially adjust the base position of the lower die base mechanism 6. The metal sealing plate 604 is fixed with the mounting bolt 613 to facilitate the metal sealing plate 604 to tightly seal the slot on the top of the lower die base assembly 603. The metal sealing plate 604 and the slot of the lower die base assembly 603 are processed closely and seamlessly to avoid the impact on the plate during stamping. The metal sealing plate 604 and the mounting bolt 613 are fixedly installed to facilitate The metal sealing plate 604 is fixed and limited in the groove at the top of the lower mold base assembly 603 by the threaded connection of the mounting bolt 613, so as to ensure a stable connection and prevent it from falling off. When the metal sealing plate 604 and the mounting bolt 613 need to be disassembled and assembled, it is only necessary to fit the top of the metal sealing plate 604 through a strong magnet such as a neodymium magnet, and drive the mounting bolt 613 to rotate by gradually and slowly rotating the metal sealing plate 604, so that the mounting bolt 613 is disengaged from the lower bolt hole 608, thereby achieving the disassembly and assembly effect, which is convenient for coordinated operation.

[0039] In another embodiment, Figure 1-Figure 9As shown, the inner side of the movable sleeve 606 is movably sleeved with a limiting movable ring 607 through an adapting groove, and the inner side of the limiting movable ring 607 is fixedly sleeved with a lower adjusting bolt 609, which movably penetrates the movable sleeve 606 and extends to the outside of the movable sleeve 606, and the outer side of the lower adjusting bolt 609 is threadedly sleeved with an adjusting screw barrel 610, which movably penetrates the lower template 1 and the mounting seat 1 601 and movably extends to the inner side of the base mechanism 7, and the outer side of the bottom end of the lower adjusting bolt 609 is threadedly connected with a plurality of limiting anti-slip nuts 611, and the bottom of the lower adjusting bolt 609 is fixedly installed with a fixed adjusting nut 612.

[0040] When the components of the lower die base mechanism 6 are adjusted, the position of the lower die base component 603 needs to be adjusted, and the limiting anti-slip nut 611 is rotated. At this time, the limit on the lower adjusting bolt 609 is released. At this time, the fixed adjusting nut 612 is rotated to drive the threaded connection between the lower adjusting bolt 609 and the adjusting screw barrel 610, and the adjusting screw barrel 610 is in a stable position under the limit of the limiting movable plate 704. At this time, the lower adjusting bolt 609 is rotated through the limiting movable ring 607 and the movable sleeve 606, thereby achieving the pulling displacement of the movable sleeve 606, and the movable sleeve 606 and the outer shell of the lower die base component 603 are connected to a stable position through the threaded penetration between the mounting bolt 613 and the lower bolt hole 608, thereby through the movable sleeve 606 Drive the lower die base assembly 603 to achieve a change in displacement, and then adjust the height position of the lower die base assembly 603. After the adjustment is completed, rotate the limit anti-slip nut 611 and the lower adjusting bolt 609 to release the limit on the bottom thread position, and then limit it through double nuts or multiple nuts and anti-slip nuts to reduce looseness and extend the stamping time, so as to achieve point-to-point adjustment of different lower die base assemblies 603. If the lower die base assembly 603 is gradually unified, it is necessary to use a flat metal panel to lay it on the top of the lower die base assembly 603, so as to facilitate the adjustment and positioning of the bottom bolts, and scale lines can be coated on the outside of the lower adjusting bolt 609 and the adjusting screw barrel 610, so that the operator can observe the adjustment position during adjustment, thereby facilitating the adjustment of the height.

[0041] In another embodiment, Figure 1-Figure 4 , Fig.10 and Fig.11As shown, the base mechanism 7 includes a lower mounting frame 701, which is fixedly mounted on the bottom of the lower template 1, and the inner side of the lower mounting frame 701 is movably sleeved with a limiting movable plate 704, and the adjusting screw barrel 610 passes through and is fixedly sleeved inside the limiting movable plate 704. The inner side of the bottom end of the lower mounting frame 701 is movably sleeved with a disassembly and assembly limiting plate 705, and the internal thread of the disassembly and assembly limiting plate 705 passes through a plurality of fixing bolts 702, which are threadedly connected and pass through the outer side of the lower mounting frame 701, and the fixing bolts 702 are circumferentially distributed on the outer sides of the disassembly and assembly limiting plate 705 and the lower mounting frame 701, and a fixed bottom plate 703 is movably mounted on the bottom of the lower mounting frame 701, and a plurality of support columns 706 are fixedly mounted on the top of the fixed bottom plate 703, and the top of the support column 706 is movably contacted with the bottom of the disassembly and assembly limiting plate 705, and the specifications and dimensions of the support column 706 and the lower mounting frame 701 are adapted to the specifications and dimensions of the lower template 1.

[0042] When making adjustments, the base mechanism 7 supports and stabilizes the internal structure. For example, the limiting movable plate 704 fixes and limits the lower adjusting bolt 609, and the movable sleeve itself is limited inside the limiting movable plate 704. The rebound mechanism 8 is fixedly supported by the top mounting seat 806, and the rebound mechanism 8 is bolted by the disassembly and assembly limit plate 705. The disassembly and assembly limit plate 705 itself is fixed by the fixing bolts 702, so as to facilitate the disassembly and assembly and adjustment of the position of the structure, and facilitate subsequent maintenance and adjustment of the position. After the fixed bottom plate 703 and the support column 706 are installed on the supporting surface by bolts, the bottom of the disassembly and assembly limit plate 705 is supported to increase the support effect on the structure, provide structural support for the position of the rebound mechanism 8, and ensure the stability of the structure.

[0043] In another embodiment, Figure 1-Figure 11As shown, the rebound mechanism 8 includes a plurality of hydraulic piston cylinders 804, the hydraulic piston cylinders 804 are movably sleeved on the inner side of the disassembly and assembly limit plate 705, the bottom of the hydraulic piston cylinder 804 is fixedly installed with a bottom mounting ring seat 807, the bottom mounting ring seat 807 is fixedly installed on the bottom of the disassembly and assembly limit plate 705 by bolts, the inner side of the hydraulic piston cylinder 804 is sealed and movably sleeved with a hydraulic piston head 805, the top of the hydraulic piston head 805 is fixedly installed with a top mounting seat 806, and the top mounting seat 806 is connected to the hydraulic piston head 805. The hydraulic piston cylinder 804 is fixedly mounted on the bottom of the limit movable plate 704 by bolts, and the specifications and dimensions of the top mounting seat 806 are adapted to the specifications and dimensions of the hydraulic piston cylinder 804. The hydraulic piston cylinder 804 is evenly distributed on the opposite sides of the limit movable plate 704 and the disassembly limit plate 705 in a circular manner, and the hydraulic piston cylinder 804 is circumferentially located on the outside of the limit ring seat 605. The bottom end of the hydraulic piston cylinder 804 is connected to a hydraulic oil transmission pipe 808, and the hydraulic oil transmission pipe 808 is movable and penetrates to the disassembly limit plate 705. The bottom of the hydraulic oil transmission pipe 808 is connected to the pressure equalizing hollow disk 809 at the opposite end, and the bottom end of the pressure equalizing hollow disk 809 is connected to the connecting pipe 801, which movably penetrates to the bottom of the fixed bottom plate 703. Two sealing pistons 811 are movably sleeved on the inner side of the connecting pipe 801. Reset springs 812 are fixedly installed on the opposite sides of the two sealing pistons 811. The reset spring 812 is movably sleeved inside the connecting pipe 801, and the connecting pipe 801 and the pressure equalizing hollow disk 809 are connected to the connecting pipe 801. Hydraulic oil is arranged inside the hollow disk 809, the hydraulic oil transmission pipe 808 and the hydraulic piston cylinder 804. A nut fixing mounting part 802 is fixedly installed at one end of the connecting pipeline 801 away from the pressure-equalizing hollow disk 809. The inner thread of the nut fixing mounting part 802 is sleeved with a limit adjustment bolt 803. A hexagonal groove 810 is provided inside the limit adjustment bolt 803. The end of the limit adjustment bolt 803 away from the hexagonal groove 810 is movably connected to one side of the sealing piston 811.

[0044] After the stamping of the lower die seat mechanism 6 is completed, the upper die seat mechanism 9 and the lower die seat mechanism 6 are separated, and the limiting pressure is released. At this time, the extrusion state of the return spring 812 is reset. Since one side of the sealing piston 811 is stably supported by the limiting adjustment 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 pipeline 801 to move. The hydraulic oil is pressure-equalized by the pressure-equalizing hollow disk 809 and enters the hydraulic oil transmission pipe 808, and then is transmitted to the inside of the hydraulic piston cylinder 804 through the hydraulic oil transmission pipe 808, thereby lifting the hydraulic piston head 805 through the hydraulic oil, and the top of the hydraulic piston head 805 lifts the limiting movable plate 704.
