It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0025] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0026] See also Figures 1 to 5 The embodiment of the utility model provides a fast positioning stamping die, which includes: a lower die frame 1, the upper surface of the lower die frame 1 is fixedly installed with guide columns 11 at four corners, the four guide columns 11 are slidably installed with guide sleeves 12, the four guide sleeves 12 are commonly fixedly installed with an upper die frame 2, the bottom of the upper die frame 2 is fixedly installed with an upper template 3, and the bottom end of the upper template 3 is fixedly installed with a punch head 4;

[0027] Two T-shaped frames 13 are provided, and the two T-shaped frames 13 are symmetrically mounted on the lower mold frame 1, and the two T-shaped frames 13 are mounted with a clamping mechanism 5, and the clamping mechanism 5 includes a bidirectional threaded rod 51, and the bidirectional threaded rod 51 is rotatably mounted on the two T-shaped frames 13, and a clamping plate 52 is symmetrically threadedly mounted on the bidirectional threaded rod 51, and a pre-clamping piece 7 is symmetrically mounted on the top of the clamping plate 52, and a bearing plate 6 is clamped between the two clamping plates 52;

[0028] The floating pressure mechanism 8, which is used for stamping buffer pre-pressure positioning, is installed on four guide columns 11, and the floating pressure mechanism 8 includes a floating frame 81, the floating frame 81 is slidably installed on the four guide columns 11, and the four corners of the floating frame 81 are fixedly connected with reset springs 82, the four reset springs 82 are respectively sleeved on the four guide columns 11, and the four reset springs 82 are fixedly connected to the lower mold frame 1 at one end away from the floating frame 81, and an intermediate plate 83 is symmetrically installed on the floating frame 81, and two guide rods 84 are symmetrically installed at the bottom end of the intermediate plate 83, and the two guide rods 84 are both sleeved with a connecting spring 85, and a pressure plate 86 is installed at the bottom end of the two connecting springs 85, and the pressure plate 86 is slidably matched with the two guide rods 84, and the bottom end of the pressure plate 86 is symmetrically installed with a lower pressure piece 9 that cooperates with the pre-clamp 7 for transmission.

[0029] Among them, the pre-clamp 7 includes a wedge-shaped clamp block 71, which is slidably installed on the top of the clamp plate 52 and is located directly below the pressing piece 9. An L-shaped plate 72 is installed at the end of the wedge-shaped clamp block 71 away from the T-frame 13, and connecting springs 73 are symmetrically installed on the L-shaped plate 72. The end of the connecting spring 73 away from the L-shaped plate 72 is fixedly connected to the clamp plate 52. The pressing piece 9 includes an extrusion spring 91, and the top of the extrusion spring 91 is fixedly connected to the pressure plate 86.

The wedge block 71 is provided with an inclined surface that slidably cooperates with the pressing wedge block 92.

[0030] It should be noted that: when in use, the material plate is placed on the punch plate 6 and located between the wedge-shaped clamping blocks 71 of the two clamping plates 52. Then, when punching, the upper die frame 2 moves along the guide column 11 to the lower die frame 1, driving the upper die plate 3 and the punch head 4 to approach the punch plate 6. Before approaching, the upper die plate 3 first contacts the floating frame 81, so that during the movement, the floating frame 81 is synchronously pressed to slide downward on the four guide columns 11. During the sliding process, the pressing plate 86 is synchronously moved downward through the middle plate 83. When the stamping is completed, the upper mold frame 2 moves upward, and the reset spring 82 drives the floating frame 81 to automatically reset upward, thereby automatically releasing the clamping and pressing of the material sheet, and stamping the material.

[0031] In the embodiments of the present invention, please refer to Figure 1 , Figure 3 and Figure 4 The bottom end of the clamping plate 52 is fixedly mounted with an insertion rod 521, and one end of the insertion rod 521 away from the clamping plate 52 is movably inserted on the T-shaped frame 13;

[0032] It should be noted that: when installing the impact plate 6, when the bidirectional threaded rod 51 is rotated, the clamping plate 52 is movably connected with the T-frame 13 using the insertion rod 521, thereby limiting the clamping plate 52 from rotating with the bidirectional threaded rod 51, thereby achieving centering and clamping the impact plate 6. When disassembly is required, it is only necessary to twist the bidirectional threaded rod 51 in the opposite direction.

[0033] In the embodiments of the present invention, please refer to Figure 3 and Figure 4 A positioning pin 522 is fixedly installed on one side of the top of the clamping plate 52, and a pin hole that cooperates with the positioning pin 522 is opened on the outer side of the impact plate 6;

[0034] It should be noted that when the clamping plate 52 is used to center and clamp the punching plate 6, the positioning pin 522 cooperates with the pin hole plug pin to achieve precise positioning and clamping, thereby ensuring the stamping accuracy.

[0035] In the embodiments of the present invention, please refer to Figure 3 and Figure 4 A through hole 501 slidably matched with the guide rod 84 is symmetrically opened on the other side of the top of the clamping plate 52.

[0036] It should be noted that: when the floating frame 81 moves downward, the sliding cooperation between the middle plate 83 on the guide rod 84 and the through hole 501 can further improve the stability of the floating frame 81 moving up and down, which is beneficial to improving the stamping accuracy.

[0037] The working principle of the fast positioning stamping die provided by the utility model is as follows:

[0038] When in use, the material plate is placed on the receiving plate 6 and located between the wedge-shaped clamping blocks 71 of the two clamping plates 52. Then, during stamping, the upper mold frame 2 moves along the guide column 11 to the lower mold frame 1, driving the upper mold plate 3 and the punch head 4 to approach the receiving plate 6. Before approaching, the upper mold plate 3 preferentially contacts the floating frame 81, so that during the movement, the floating frame 81 is synchronously pressed to slide downward on the four guide columns 11. During the sliding process, the pressure plate 86 is driven to move downward synchronously through the middle plate 83. When moving downward, under the transmission of the extrusion spring 91, the downward pressing wedge block 92 is driven to slide along the inclined surface opened by the wedge-shaped clamping block 71, thereby driving the wedge clamping block 71 to approach the material plate and automatically position and clamp the material plate. Then, the middle pressure plate 86 is moved downward to synchronously contact and squeeze the material plate, thereby completing the stamping pre-fixation, and then continues to move until the stamping is completed. When the stamping is completed, the upper mold frame 2 moves upward, and the reset spring 82 drives the floating frame 81 to automatically reset upward, thereby automatically releasing the clamping and pressing of the material plate, and stamping the material.

[0039] The circuits and controls involved in the present invention are all prior art and will not be described in detail here.

Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
