Moreover, the screws are also easily damaged by the shear force caused by the jerks, reducing their service life. Secondly, it is not convenient for the fixing seat to clamp and fix stamping dies of different sizes, thus reducing its actual application effect. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1-5 , the present utility model provides a technical solution for a stamping die fixing seat: including a mounting plate 1 and a buffer frame 2. A plurality of movable grooves 11 are provided on the upper surface of the mounting plate 1. The buffer frame 2 is connected to two symmetrical clamping components 4. A plurality of inner sleeve plates 21 are fixedly connected to the bottom surface of the buffer frame 2, and the plurality of inner sleeve plates 21 are respectively sleeved inside the plurality of movable grooves 11.

[0025] The multiple inner sleeve plates 21 are all set in an n-shaped configuration. The left and right side surfaces of each inner sleeve plate 21 are fixedly connected to the first elastic members 22 respectively, and the two first elastic members 22 are fixedly connected to the left and right side surfaces inside the same movable slot 11 respectively.

[0026] Four second elastic members 23 are fixedly connected to the inner bottom surface of each inner sleeve plate 21, and the four second elastic members 23 are all fixedly connected to the inner bottom surface of the same movable slot 11. For the jerky force generated during the stamping operation, the stamping die can drive the clamping assembly 46 and the clamping component 4 to drive the buffer frame 2 to buffer and dilute the first elastic members 22 and the second elastic members 23. At the same time, the movable plate 3 and the third elastic members 31 inside the buffer frame 2 can respond to the lateral downward jerky force of the stamping die clamped on its upper surface. In this way, the mounting plate 1 can be buffered and protected, thereby increasing the service life of this fixing seat.

[0027] The upper surface inside the buffer frame 2 is sleeved with the movable plate 3. A plurality of third elastic members 31 are fixedly connected to the front and rear side surfaces of the movable plate 3 respectively. The plurality of third elastic members 31 are divided into two groups and are fixedly connected to the front and rear side surfaces inside the buffer frame 2 respectively. By arranging the movable plate 3, when the clamped and fixed die generates a lateral jerky force, it can be buffered and diluted through the third elastic members 31 and the second elastic members 23. In this way, the protective effect of this fixing seat on the mounting plate 1 can be improved, thereby increasing the service life.

[0028] The two clamping components 4 both include fixing plates 41. The fixing plates 41 are set in an L-shaped configuration and are fixedly connected to the side surface of the buffer frame 2. The fixing plates 41 are respectively sleeved with two movable columns 42 through two first round holes opened. One ends of the two movable columns 42 are fixedly connected to a linkage plate 43. The linkage plate 43 is rotatably connected to a first threaded rod 45 through a bearing. The first threaded rod 45 is threadedly connected to the fixing plate 41. One end of the first threaded rod 45 is fixedly connected to a pushing disk 451, and the other end of the first threaded rod 45 is fixedly connected to a first handwheel. By rotating the first handwheel, the first handwheel drives the first threaded rod 45 to rotate synchronously, so that the first threaded rod 45 moves under the fixed support of the fixing plate 41. In this way, the moving first threaded rod 45 can push the pushing disk 451 against the clamping plate 461 on the clamping assembly 46, thereby pushing the clamping plate 461 to move. At the same time, the clamping plate 461 drives the two movable columns 42 to move synchronously and squeezes the fourth elastic member 44 to generate a reverse elastic thrust. In this way, the two clamping plates 461 can move relatively to clamp and fix the stamping die. Then, by rotating the second handwheel in the reverse direction, the two clamping plates 465 can perform secondary clamping and fixing on the die. Then, the stamping operation can be carried out.

[0029] The opposite sides of the linkage plate 43 and the fixed plate 41 are fixedly connected to two fourth elastic members 44. The two fourth elastic members 44 are respectively sleeved on two movable columns 42. The other ends of the two movable columns 42 are both connected to the clamping assembly 46. By providing the fourth elastic members 44, when the clamping plate 461 moves reversely and expands, it can rely on the pushing of the fourth elastic members 44 to drive the movement. In this way, it is convenient to release the fixed mold.

[0030] The clamping assembly 46 includes a clamping plate 461, two synchronous shafts 463 and two clamping plates 465. The clamping plate 461 is fixedly connected to the other ends of the two movable columns 42. The clamping plate 461 is respectively sleeved on the two synchronous shafts 463 through two second circular holes opened.

[0031] The opposite ends of the two synchronous shafts 463 are respectively fixedly connected to the two clamping plates 465. The opposite ends of the two synchronous shafts 463 are both fixedly connected with limiting rings 466. The two limiting rings 466 are respectively vertically offset from the two clamping plates 465. By providing the synchronous shafts 463, the rotation of the two clamping plates 465 can be restricted. In this way, the second threaded rod 462 and the internal threaded rod 464 can drive the clamping plates 465 to move relatively or away from each other synchronously, so as to facilitate dealing with punching molds of different sizes.

[0032] The clamping plate 461 is rotationally connected to the second threaded rod 462 through a bearing. The second threaded rod 462 is threadedly connected to the internal threaded rod 464 through a spiral hole opened. The internal threaded rod 464 is fixedly connected to one of the clamping plates 465. The second threaded rod 462 is rotationally connected to the other clamping plate 465 through a bearing. A second handwheel is fixedly connected to the end of the second threaded rod 462. By rotating the second handwheel, the second handwheel drives the second threaded rod 462 to rotate. At the same time, the second threaded rod 462 drives the other clamping plate 465 to move. At the same time, the second threaded rod 462 drives the internal threaded rod 464 that is restricted from rotating to move synchronously in the direction opposite to the other clamping plate 465, so that the internal threaded rod 464 pushes one of the clamping plates 465 to move reversely. In this way, the distance between the two clamping plates 465 can be expanded, so as to facilitate dealing with the size of the punching mold to be processed.

[0033] The operation steps of the present utility model are as follows:

[0034] By rotating the second handwheel, the second handwheel drives the second threaded rod 462 to rotate. At the same time, the second threaded rod 462 drives the other clamping plate 465 to move. At the same time, the second threaded rod 462 drives the internal threaded rod 464 that is restricted from rotating to move synchronously in the direction opposite to the other clamping plate 465, so that the internal threaded rod 464 pushes one of the clamping plates 465 to move reversely. In this way, the distance between the two clamping plates 465 can be expanded, so as to facilitate dealing with the size of the punching mold to be processed;

[0035] Then rotate the first handwheel on the two clamping assemblies 4. The first handwheel drives the first threaded rod 45 to rotate synchronously, so that the first threaded rod 45 moves under the fixed support of the fixing plate 41. In this way, the moving first threaded rod 45 can push the pushing disc 451 against the clamping plate 461 on the clamping assembly 46, thereby driving the clamping plate 461 to move. At the same time, the clamping plate 461 drives the two movable columns 42 to move synchronously and squeezes the fourth elastic member 44 to generate a reverse elastic thrust. In this way, the two clamping plates 461 can move relatively to clamp and fix the stamping die. Then rotate the second handwheel in the reverse direction, so that the two clamping plates 465 perform secondary clamping and fixing on the die, and then the stamping operation can be carried out;

[0036] During the stamping operation, the jerks generated can cause the stamping die to drive the clamping assembly 46 and the clamping assembly 4 to drive the buffer frame 2 to buffer and dilute the first elastic member 22 and the second elastic member 23. At the same time, the movable plate 3 and the third elastic member 31 inside the buffer frame 2 can respond to the lateral downward jerks of the stamping die clamped on its upper surface. In this way, the mounting plate 1 can be buffered and protected, thereby increasing the service life of the fixing seat.
