[0023] Furthermore, the lower end of the lower mold 6 is inserted into the first rectangular limiting groove 101 for limiting connection, the upper end of the lifting tube 2 passes through the upper end of the first circular groove 103 and is inserted into the second circular groove 602 on the lower mold 6, and the lower end of the lifting tube 2 passes through the lower end of the first circular groove 103 and extends to the inside of the transmission groove 102. Rectangular limiting grooves 104 are provided on both sides of the inner end surface of the first circular groove 103, and rectangular limiting plates 201 are fixedly connected on both sides of the middle part of the lifting tube 2. The two rectangular limiting plates 201 on the lifting tube 2 are respectively inserted into the two rectangular limiting grooves 104 for limiting connection, and the rectangular limiting plates 201 slide up and down in the rectangular limiting grooves 104 to prevent the lifting tube 2 from rotating.

[0024] Furthermore, an internal threaded tooth 202 is provided on the middle end face inside the lifting tube 2, and an external threaded portion 301 is provided on the middle end face of the transmission shaft 3. The external threaded portion 301 on the transmission shaft 3 is meshed and connected with the internal threaded tooth 202 inside the lifting tube 2. Since the lifting tube 2 cannot rotate, when the transmission shaft 3 rotates, it pushes the lifting tube 2 to rise and fall.

[0025] Furthermore, rectangular cross-section annular limiting grooves 203 are provided on both side end faces of the upper end of the lifting tube 2, and a rectangular cross-section limiting ring 401 is fixedly connected to the middle part of the outer side of the circular tap seat 4. The rectangular cross-section limiting ring 401 on the circular tap seat 4 is inserted into the rectangular cross-section annular limiting groove 203 inside the lifting tube 2 for limiting connection, and the circular tap seat 4 is driven to be lifted and lowered by lifting and lowering the lifting tube 2.

[0026] Furthermore, a rectangular limiting plug plate 402 is fixedly connected to the lower end of the circular tap seat 4, and a rectangular limiting slot 302 is provided between the middle part of the transmission shaft 3 and the upper end surface of the transmission shaft 3. The rectangular limiting plug plate 402 on the circular tap seat 4 is inserted into the rectangular limiting slot 302 on the transmission shaft 3 for limiting connection. When the lifting tube 2 is lifted and lowered by the transmission shaft 3, the circular tap seat 4 is also driven to rotate.

[0027] Furthermore, the lower end of the transmission shaft 3 passes through the lower end of the lifting tube 2 and extends to the inside of the transmission groove 102 and is fixedly connected to the worm wheel 303. A worm 5 is rotatably connected to one side of the middle part of the transmission groove 102. The worm 5 is meshed with the teeth of the worm wheel 303. One end of the worm 5 passes through the inside of the base 1 and extends to one side and is fixedly connected to a turntable 501. The worm 5 is driven to rotate by rotating the turntable 501, and the worm 5 drives the transmission shaft 3 to rotate.

[0028] Furthermore, a fixing ring 603 is fixedly connected to the upper end of the second circular groove 602 of the lower mold 6, and the upper end of the tapping tap 403 passes through the upper end of the lifting tube 2 and is inserted into the middle of the fixing ring 603. When the lifting tube 2 rises, the circular tap seat 4 is driven to rise, so that the upper end of the tapping tap 403 passes through the middle of the fixing ring 603 and is inserted into the lower mold groove 601. At the same time, the circular tap seat 4 is driven to rotate through the transmission shaft 3, and then the tapping tap 403 is driven to rotate, so that the tapping tap 403 is inserted into the lower mold groove 601 and rotates synchronously to tap the product.

[0029] Working principle: When in use, put the product raw material into the lower die groove 601, and use the stamping device to close the upper die and the lower die 6 to stamp the product raw material. After closing, turn the turntable 501 to drive the worm 5 to rotate, and then the worm 5 drives the transmission shaft 3 to rotate. The external threaded part 301 on the transmission shaft 3 is meshed with the internal threaded teeth 202 inside the lifting tube 2. The two rectangular limit pieces 201 on the lifting tube 2 are respectively inserted into the two rectangular limit sliding grooves 104 for limit connection. When the lifting tube 2 is lifted, the rectangular limit piece 201 is in the rectangular limit position. The lifting tube 2 can slide up and down in the slide groove 104 to prevent the lifting tube 2 from rotating. Since the lifting tube 2 cannot rotate, the transmission shaft 3 pushes the lifting tube 2 to rise when it rotates. The lifting and lowering of the lifting tube 2 drives the circular tap seat 4 to lift and lower, so that the upper end of the tapping tap 403 passes through the middle of the fixing ring 603 and is inserted into the lower die groove 601. At the same time, the circular tap seat 4 is driven to rotate by the transmission shaft 3, and then the tapping tap 403 is driven to rotate. When the tapping tap 403 is inserted into the lower die groove 601, it rotates synchronously to tap the product, so that the tapping operation is completed synchronously when the product is stamped.

[0030] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
