One side of the first sliding groove 161 is fixedly connected with a first tension spring 163. The other end of the first tension spring 163 is fixedly connected with one side of the sliding block 168. The insertion rod 167 is inserted with one side of the clamping block 18. An extrusion rod 165 is slidably connected in the second sliding groove 162. One end of the extrusion rod 165 penetrates through the fixed cylinder 10 and is slidably connected. One end of the extrusion rod 165 is in contact with the upper surface of the threaded ring 17. The top of the extrusion rod 165 is fixedly connected with an extrusion block 166.

[0033] The bottom of the extrusion block 166 is fixedly provided with a second tension spring 164, the other end of the second tension spring 164 is fixedly connected with the inner wall of the bottom of the second sliding groove 162, and the second tension spring 164 is sleeved outside the extrusion rod 165.

[0034] It should be noted that, through the linkage design of the thread ring 17 in the clamping mechanism 16 and the extrusion rod 165 and the extrusion block 166, the quick plug-in fixing of the clamping block 18 and the plug rod 167 is realized, without manual fastening;

[0035] Compared with the problem that the punch core 11 in the traditional ton barrel bottom plate stamping forming device needs to be manually fastened and disassembled and takes a long time, the installation and disassembly time of the punch core 11 is significantly shortened, the production efficiency is improved, the equipment downtime is reduced, and the production line can more flexibly cope with the production needs of ton barrel bottom plates of different specifications.

[0037] The cooperation design of the clamping block 18 and the clamping groove of the fixing cylinder 10, combined with the rotation control of the thread ring 17, realizes the quick replacement of the punch core 11, compared with the problem that the punch core 11 in the traditional ton barrel bottom plate stamping forming device is fixed and cannot be adjusted and cannot adapt to products of multiple specifications, so that the same equipment can quickly switch punch cores 11 of different specifications, improve the equipment utilization rate, greatly reduce the equipment investment cost of enterprises, at the same time, reduce the production interruption caused by replacing the mold, and improve the overall production efficiency.

[0038] As shown in Figures 1-3 The upper surface of the workbench 1 is provided with a concave die core 12, the two sides of the concave die core 12 are fixedly connected with connecting blocks 13, the upper surface of the connecting block 13 is provided with a through hole, the through hole is rotatably connected with a threaded rod 14, and the upper surface of the workbench 1 is provided with a plurality of adjusting screw holes 15, and the threaded rod 14 is threadedly connected with the adjusting screw hole 15.

[0039] It should be noted that, through the setting of the concave die core 12, the connecting block 13 and the threaded rod 14, the quick adjustment of the concave die width is realized, only the threaded rod 14 needs to be rotated, so that it is threadedly connected with the adjusting screw hole 15 on the workbench 1, so as to change the position of the concave die core 12, adapt to the production needs of ton barrel bottom plates of different specifications;

[0040] Compared with the problem that the die fixed in the traditional ton barrel bottom plate stamping forming device cannot be adjusted and cannot adapt to multiple specifications of products, the specification switching time is greatly shortened, the production flexibility is improved, and the device can quickly respond to different order demands.

[0041] The cooperation of the threaded rod 14 and the adjusting threaded hole 15 ensures the position control of the die core 12 during the adjustment process. This design avoids the decline of stamping precision caused by position deviation and ensures the forming quality of the ton barrel bottom plate. Compared with the problem that the die adjustment is not uniform and the product consistency is poor in the prior art, the stamping precision is effectively improved, the product qualification rate is significantly improved, and the waste rate caused by size mismatch is reduced.

[0042] The adjustable setting of the die core 12 enables the same device to produce ton barrel bottom plates of multiple specifications, greatly improves the utilization rate of the device, eliminates the need to prepare multiple dies for different specifications of products, reduces the equipment investment cost of the enterprise, and reduces the production interruption caused by die replacement;

[0043] Compared with the problem that multiple dies need to be prepared for different specifications of products in the traditional ton barrel bottom plate stamping forming device, the utilization rate of the device is significantly improved, economic benefits are brought to the enterprise, and the production line can more efficiently meet the diversified market demand.

[0044] As shown in Figures 1-3 The circumferential outer wall of the fixed cylinder 10 is fixedly connected with two limiting rods 9, one end of each of the two limiting rods 9 is fixedly connected with a limiting sleeve 8, the circumferential inner wall of each of the two limiting sleeves 8 is slidably connected with the circumferential outer wall of a fixed rod 2, the circumferential outer wall of each of the two fixed rods 2 is fixedly connected with a limiting plate 5, and the limiting sleeve 8 on the same side is located between the mounting plate 3 and the limiting plate 5. The circumferential outer wall of each of the two fixed rods 2 is fixedly connected with two support rods 4, and the bottom of each of the two support rods 4 is fixedly connected with the upper surface of the workbench 1.

[0045] It should be noted that the fixed cylinder 10 moves up and down under the drive of the hydraulic rod 7 through the cooperation of the limiting rod 9 and the limiting sleeve 8, the limiting sleeve 8 slides on the fixed rod 2, and forms a double limiting structure with the limiting plate 5, effectively preventing the lateral deviation of the fixed cylinder 10 during movement;

[0046] Compared with the problem that the fixed cylinder 10 lacks an effective limiting device and is prone to shaking during movement in the prior art, the stamping precision is significantly improved, the size consistency of the ton barrel bottom plate is ensured, and the wear between the fixed cylinder 10 and the hydraulic rod 7 is reduced, prolonging the service life of the device.

[0047] The limiting sleeve 8 is located between the mounting plate 3 and the limiting plate 5, providing an accurate movement trajectory for the fixed cylinder 10, which ensures that the fixed cylinder 10 always maintains the correct vertical position during upward and downward movement, avoiding stamping position deviation caused by lateral displacement;

[0048] Compared with the problem of inconsistent product size caused by the shaking of the fixed cylinder 10 in the traditional ton barrel bottom plate stamping forming device, the product qualification rate is effectively improved, the waste product generation is reduced, and the production line can more efficiently meet the production demand.

[0049] The support rod 4 stably connects the fixed rod 2 to the workbench 1, and together with the limiting rod 9, the limiting sleeve 8 and the limiting plate 5, forms a complete limiting system, enhances the structural strength and stability of the whole device, and makes the fixed cylinder 10 highly stable during high-speed stamping;

[0050] Compared with the problem of unstable fixed structure and easy loosening after long-term use in the prior art, the equipment failure rate is greatly reduced, the maintenance downtime is reduced, and the continuous operation capacity and production efficiency of the equipment are improved.

[0051] When the punch core 11 is replaced, the clamping block 18 is clamped with the clamping groove at the bottom of the fixed cylinder 10, and then the threaded ring 17 is screwed with the bottom of the fixed cylinder 10. During screwing, the threaded ring 17 moves upward, so that the upper surface of the threaded ring 17 contacts and extrudes the rod 165, so that the extrusion block 166 is driven upward by the extrusion block 166. When the extrusion block 166 rises, the upper surface of the extrusion block 166 is a slope, which contacts the bottom of the sliding block 168, so that the sliding block 168 moves towards the clamping block 18, so that the insertion rod 167 on one side of the sliding block 168 is inserted with the clamping block 18, thereby fixing the punch core 11.

[0052] When the punch core 11 is replaced, the threaded ring 17 is separated from the fixed cylinder 10, and the first tension spring 163 and the second tension spring 164 are arranged to reset the sliding block 168 and the extrusion block 166, so that the insertion rod 167 is separated from the clamping block 18.

[0053] When the hydraulic cylinder 6 drives the hydraulic rod 7 to move the fixed cylinder 10, the fixed cylinder 10 drives the limiting rod 9 to move, and the limiting rod 9 drives the limiting sleeve 8 to slide on the outer wall of the fixed rod 2, thereby limiting the movement of the fixed cylinder 10.

[0054] When the concave die core 12 is replaced, the threaded rod 14 on the connecting block 13 is screwed with the corresponding adjusting threaded hole according to the width of the concave die core 12.

[0055] According to the ideal embodiment of the utility model, the related personnel can make various changes and modifications without deviating from the technical idea of the utility model. The technical scope of the utility model is not limited to the content of the specification, and must be determined by the scope of claims.
