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.
[0031] Example 1
[0032] Please see Figures 1-7 A sheet metal stamping die clamping device includes a stamping table 1, a top seat 2 above the stamping table 1, a telescopic stamping device 3 fixedly mounted on the top seat 2, an upper stamping die 4 fixedly mounted at the lower telescopic end of the telescopic stamping device 3, a lower stamping die 5 on the stamping table 1, a circular positioning ring 6 located on the side of the lower stamping die 5, a sliding block 7 slidably connected to the side of the positioning ring 6, a sliding groove 8 adapted to the sliding block 7 penetrating the side of the positioning ring 6, a tightening bolt 9 threaded through and connected to the sliding block 7, and one end of the tightening bolt 9 located inside the positioning ring 6 having a fitting adapted to the side of the lower stamping die 5. The clamping plate 10 has a first limiting nut 11 threadedly connected to the side of the tightening bolt 9. The upper part of the positioning ring 6 has a moving groove 12 that communicates with the sliding groove 8. A positioning bolt 13 with one end threadedly connected to the upper side of the sliding block 7 passes through the moving groove 12. The side of the positioning ring 6 has several clearance openings 25 that are adapted to the sliding groove 8 and are adapted to the sliding block 7. The side of the positioning ring 6 has a mounting plate 26 fixedly installed. The mounting plate 26 has several arc-shaped grooves 27. The lower part of the lower stamping die 5 has a positioning seat 30 fixedly installed. The upper part of the stamping table 1 has a positioning groove 31 that is adapted to the positioning seat 30.
[0033] In this specific embodiment, when installing the lower stamping die 5, the positioning seat 30 at the bottom of the lower stamping die 5 is inserted into the positioning groove 31. One end of the fastener passes through the arc-shaped groove 27 and is threaded to the stamping table 1. The positioning ring 6 can rotate by sliding along the side of the fastener via the arc-shaped groove 27. The sliding block 7 moves within the sliding groove 8 according to the side position of the lower stamping die 5. The positioning bolt 13 slides within the moving groove 12, aligning the clamping plate 10 with the side position of the lower stamping die 5. The positioning bolt 13 is then tightened to limit and fix the position of the sliding block 7. Finally, the clamping plate 10 is pressed against the side position of the lower stamping die 5 by rotating the tightening bolt 9. The position of the clamping plate 10 is adjusted by tightening the first limiting nut 11 to limit and fix the position of the top bolt 9. The sliding block 7, which can slide in the sliding groove 8, and the top bolt 9 are used to adjust the position of the clamping plate 10, so that the lower stamping die 5 of different shapes can be clamped and fixed, thereby improving the applicability of the stamping clamping device. The sliding block 7 can be taken out or inserted into the sliding groove 8 through the clearance port 25. The number of clamping plates 10 can be selected according to the actual situation. When stamping sheet metal parts, the sheet metal parts are placed on the upper part of the lower stamping die 5, and the telescopic stamping device 3 is opened. The telescopic end of the telescopic stamping device 3 drives the upper stamping die 4 to move down, thereby completing the stamping of the sheet metal parts.

[0035] Please see Figure 6 This embodiment includes the above-described embodiments, and further includes: an adjusting seat 15 on one side of the clamping plate 10; a positioning plate 14 on the side of the adjusting seat 15 facing the downward stamping die 5; a first adjusting threaded rod 16 threaded through and connected to the adjusting seat 15, with one end rotatably connected to the positioning plate 14; a second limiting nut 17 threadedly connected to the side of the first adjusting threaded rod 16; a limiting rod 21 threaded through the adjusting seat 15 fixedly installed on one side of the positioning plate 14; an adjusting groove 18 adapted to the adjusting seat 15 threaded through the opposite side of the clamping plate 10; a second adjusting threaded rod 19 threaded through and connected to the upper end of the clamping plate 10, with one end rotatably connected to the upper part of the adjusting seat 15; a third limiting nut 20 threadedly connected to the side of the second adjusting threaded rod 19; a clearance step 28 adapted to the positioning plate 14 on the side of the clamping plate 10 facing the downward stamping die 5; and an abutment groove 29 adapted to the tightening bolt 9 on the side of the clamping plate 10 facing the positioning ring 6.
[0036] In this specific embodiment: After the clamping plate 10 clamps the lower stamping die 5, the second adjusting threaded rod 19 is rotated, causing the adjusting seat 15 to slide within the adjusting groove 18, thus adjusting the position of the positioning plate 14 to match the upper position of the lower stamping die 5. The positioning plate 14 can then position the sheet metal part to be stamped. The third limiting nut 20 is tightened to fix the position of the adjusting seat 15. The first adjusting threaded rod 16 is rotated, driving the positioning plate 14 to move. The positioning plate 14 is positioned by the limiting rod 21, which can adjust the position of the positioning plate 14 and position sheet metal parts of different sizes to be stamped. The second limiting nut 17 is locked to limit and fix the position of the positioning plate 14. The clearance step 28 is used to make way for the positioning plate 14, thereby increasing the positioning range of the positioning plate 14 for the sheet metal parts to be stamped. One end of the tightening bolt 9 abuts in the abutment groove 29, which allows for the replacement of clamping plates 10 of different heights or tightening bolts 9 of different lengths, further improving the applicability of the sheet metal parts to be stamped.
