[0026] A lower template 1, the top of which is provided with a sliding mechanism, and a stamping seat 8 is provided on the sliding mechanism;

[0027] The sliding mechanism comprises:

[0028] A groove is provided on the lower template 1, a threaded rod 16 is provided inside the groove, one end of the threaded rod 16 is provided on the output end of the motor 17, a movable block 18 is provided in the middle of the threaded rod 16, a threaded hole is provided on the side of the movable block 18, the threaded rod 16 passes through the movable block 18, the threaded rod 16 and the movable block 18 are screwed together, a connecting block 19 is fixed on the top of the movable block 18, a stamping seat 8 is provided on the top of the connecting block 19, and positioning rods 6 are provided at the four corners of the top of the stamping seat 8;

[0029] A top mounting seat 2 is arranged above the punching seat 8, an upper template 13 is arranged below the top mounting seat 2, a slide groove 14 is opened on one side of the upper template 13, a slidable slider 22 is arranged in the slide groove 14, a main hydraulic cylinder 15 is arranged on the slider 22, the telescopic end of the main hydraulic cylinder 15 passes through the bottom of the slider 22, and an upper pressing plate 4 is fixed, and positioning sleeves 5 are arranged at the four corners of the bottom of the upper pressing plate 4, and two auxiliary hydraulic cylinders 12 are symmetrically arranged on the upper template 13, and the telescopic ends of the two auxiliary hydraulic cylinders 12 are connected to the slider 22;

[0030] Specifically, when in use, the upper template and the lower template are installed. After the installation is completed, the positioning sleeve and the positioning rod are used to detect the installation position. The laser light above the positioning sleeve is used to penetrate the central opening of the partition 20 and illuminate the top of the buffer block 7. Because a positioning point is provided above the buffer block 7, the user can observe whether the light spot coincides with the positioning point above the buffer block 7 to determine whether the installation position is offset. If the position is offset, the adjustment function of the sliding mechanism and the auxiliary hydraulic cylinder 12 is used to adjust it. The threaded rod 16 is driven to rotate by the motor 17 to move the movable block 18 and drive the stamping seat 8 to move forward and backward. When the left and right position deviation occurs, the auxiliary hydraulic cylinder 12 on the inner side of the upper template 13 is used to adjust the main hydraulic cylinder 15. Push to make the main hydraulic cylinder 15 move the upper pressure plate 4 below to the left and right. With the cooperation of the upper and lower sets of templates, the deviation position can be adjusted after the installation is completed. During processing, the stamping object is placed above the stamping seat 8, and the pushing effect of the telescopic rod 11 is used to make the clamp 10 clamp the object and limit it to ensure the stability of the object during the stamping process. When the upper pressure plate 4 falls, the positioning sleeve 5 contacts the positioning rod 6 in advance due to the position relationship. If there is no deviation in the position, the positioning rod 6 will be inserted into the interior of the positioning sleeve 5. If there is a deviation in the position, the positioning rod 6 will not be able to engage with the bottom of the positioning sleeve 5, so that the upper pressure plate 4 cannot fall, thereby preventing the stamping object from being in the wrong stamping position, resulting in the finished product not meeting expectations and causing material waste.

[0031] In some examples, a laser lamp 21 is disposed on the upper inner side of the positioning sleeve 5, a partition 20 is disposed on the inner side of the positioning sleeve 5, a hole is opened in the center of the partition 20, and the partition 20 is located below the laser lamp 21;

[0032] Specifically, the laser light 21 can shine downward through the hole opened in the center of the partition 20 to illuminate the position of the light spot, so as to preliminarily determine whether the installation position is deviated so as to make timely adjustments to prevent errors.

[0034] Specifically, the slide groove 14 can achieve a stabilizing effect when the main hydraulic cylinder 15 drives the upper pressure plate 4 to move, thereby preventing shaking that may cause poor adjustment effect.

[0035] In some examples, telescopic rods 11 are provided on both sides of the punching seat 8, and a clamping plate 10 is provided on one side of the telescopic rod 11, and the width of the clamping plate 10 is the same as the width of the punching seat 8;

[0036] Specifically, the clamping plate 10 can clamp the inner object under the push of the telescopic rod 11 to prevent the object from being displaced during the stamping process, and limit the object to ensure that the object is within the range of the stamping work area.

[0037] In some examples, a buffer block 7 is disposed above the positioning rod 6, a positioning point is disposed above the buffer block 7, the positioning rod 6 is located directly below the positioning sleeve 5, and the diameter of the positioning rod 6 is smaller than the inner diameter of the positioning sleeve 5;

[0038] Specifically, the buffer block 7 can provide a buffering force for the contact between the two components when the positioning rod 6 and the positioning sleeve 5 are sleeved, thereby preventing damage to the equipment due to collision during the stamping process.

[0039] In some examples, a protective shell 3 is provided between the upper template 13 and the top mounting seat 2, and a buffer spring 9 is provided on the bottom surface of the connecting block 19;

[0040] Specifically, the upper pressing plate 4 can perform stamping processing on the object by cooperating with the stamping seat 8. Because the bottom surface size of the pressing plate 4 is the same as that of the stamping seat 8, when the installation position is correct, the area can be reduced to facilitate loading of other components.

[0041] Through the above technical solution:

[0042] When in use, the upper template and the lower template are installed. After the installation is completed, the positioning sleeve and the positioning rod are used to detect the installation position. The laser light above the positioning sleeve is used to penetrate the central opening of the partition 20 and illuminate the top of the buffer block 7. Because a positioning point is provided above the buffer block 7, the user can observe whether the light spot coincides with the positioning point above the buffer block 7 to determine whether the installation position is offset. If the position is offset, the adjustment function of the sliding mechanism and the auxiliary hydraulic cylinder 12 is used to adjust it. The motor 17 drives the threaded rod 16 to rotate, so that the movable block 18 moves and drives the stamping seat 8 to move forward and backward. When the left and right position deviation occurs, the auxiliary hydraulic cylinder 12 on the inner side of the upper template 13 is used to push the main hydraulic cylinder 15. , so that the main hydraulic cylinder 15 moves the upper pressing plate 4 below to the left and right. With the cooperation of the upper and lower sets of templates, the deviation position can be adjusted after the installation is completed. During processing, the stamping object is placed above the stamping seat 8, and the pushing effect of the telescopic rod 11 is used to clamp the object and limit it, ensuring the stability of the object during the stamping process. When the upper pressing plate 4 falls, the positioning sleeve 5 contacts the positioning rod 6 in advance due to the position relationship. If there is no deviation in the position, the positioning rod 6 will be inserted into the interior of the positioning sleeve 5. If there is a deviation in the position, the positioning rod 6 will not be able to engage with the bottom of the positioning sleeve 5, so that the upper pressing plate 4 cannot fall, thereby preventing the stamping object from being in the wrong stamping position, resulting in the finished product not meeting expectations and causing material waste.
