DETAILED DESCRIPTION

[0025] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0026] Example 1, reference Figure 1-Figure 5, which is the first embodiment of the present invention, provides a fastener stamping die with a fine-tunable die punch, which can achieve the effect of being suitable for nuts of different sizes without disassembling the lower die 102, and includes a stamping component 100, including an upper die 101 and a lower die 102, a bearing ring 103 arranged on the lower die 102, a replacement die 104 arranged in the bearing ring 103, a punch body 105 arranged on the upper die 101, a screw hole arranged on the upper die 101, and a stud 107 arranged on the punch body 105; a switching component 200, including a stud 107 arranged on the bearing ring 103, a punch body 105 arranged on the upper die 101, and a screw hole arranged on the upper die 101. The bearing component 201 on the ring 103, the locking component 202 arranged on the bearing ring 103, the pushing component 203 arranged on the locking component 202, and the toggle component 204 arranged on the pushing component 203; the adjusting component 300, including the guiding component 301 arranged on the toggle component 204, and the pulling component 302 arranged on the guiding component 301; the lifting component 400, including the sliding component 401 arranged in the bearing component 201, the threaded component 402 arranged on the sliding component 401, and the gear component 403 arranged on the threaded component 402.

[0027] Specifically, the lower die 102 is provided with a plurality of threaded holes 106 so that the lower die 102 can be fixed by bolts. The replacement die 104 is a regular hexagonal frame. When different nuts need to be processed, only the replacement die 104 needs to be replaced. The setting of the stud 107 here can adjust the height of the punch body 105, so that nuts of different thicknesses can be punched. Here, only the height of the punch body 105 is changed. It is not limited to being completed by a threaded method, but can also be a method of matching a pin and a socket. As long as the height of the punch body 105 can be changed and the method is stable during stamping, it is acceptable. It is worth noting that in the stamping process of the nut, the nut is first a cylinder, which is placed in a replacement mold, and then extruded by the upper die 101. The replacement mold restricts the nut so that the outer end of the nut is a regular hexagon. At the same time, the punch body 105 punches the nut, thereby completing the initial forming of the nut.

[0028] Furthermore, the bearing component 201 includes six fan-shaped grooves 201a arranged on the bearing ring 103, and the six fan-shaped grooves 201a are each provided with a fan-shaped block 201b that cooperates with the replacement mold 104, and the lower end surface of the replacement mold 104 is abutted against the upper end surface of the fan-shaped block 201b; the locking component 202 includes an installation cavity 202a arranged on the bearing ring 103, and the inner wall of the installation cavity 202a is provided with six strip grooves 202b, and the six strip grooves 202b are each slidably connected with a slider 202c, the slider 202c is elastically connected to the inner wall of the strip groove 202b through a first spring 202d, and a connecting block 202e is fixedly connected to the slider 202c, and a mounting port 202f extending into the wall of the replacement mold is provided on the inner wall of the installation cavity 202a, and an insertion rod 202g that cooperates with the mounting port 202f is fixedly connected to the connecting plate 301a.

[0029] Among them, the inner walls of the six fan-shaped blocks 201b here are always at the inner end of the replacement mold 104, so that the replacement mold 104 can always be supported. The insertion rod 202g here pushes the replacement mold 104 from six directions at the same time, so that the replacement mold 104 can be calibrated to ensure that the center point of the replacement mold 104 is directly opposite to the center point of the punch body 105.

[0030] Preferably, the pushing assembly 203 includes a circular ring 203a rotatably connected to the inner wall of the mounting cavity 202a, a plurality of groups of trapezoidal blocks 203b are fixedly connected to the circular ring 203a, a cutting edge 203c cooperating with the trapezoidal blocks 203b is provided on the insert rod 202g, a plurality of trapezoidal blocks 203b are provided for each group, and the heights of the plurality of trapezoidal blocks 203b for each group are different; the toggle assembly 204 includes a first arc-shaped opening 204a provided on the supporting ring 103, the width of the first arc-shaped opening 204a is smaller than the thickness of the circular ring 203a, a T-shaped toggle block 204b is slidably connected in the first arc-shaped opening 204a, a reference line 204c is provided on the side wall of the toggle block 204b and the supporting ring 103, the toggle block 204b is fixedly connected to the circular ring 203a, and a fastening bolt 204d is threadedly connected to the toggle block 204b.

[0031] It should be noted that the height of each group of multiple trapezoidal blocks 203b is different, so the distance that the insertion rod 202g can be pushed outward is also different, and thus different sizes of replacement molds 104 are suitable for the production of nuts of different sizes. Here, multiple reference lines 204c are set on the side wall of the supporting ring 103, and the multiple reference lines 204c respectively correspond to the replacement molds 104 for common nut processing on the market.

[0032] When in use, when there is no need to replace the nut, the longer trapezoidal block 203b is against the insertion rod 202g, so that the outer end of the insertion rod 202g enters the installation port 202f of the replacement mold 104. At this time, the first spring 202d is extended, and the fastening bolt 204d is against the side wall of the load-bearing ring 103 to limit the shift block 204b and prevent the shift block 204b from self-slipping. Here, a plurality of inner grooves can be provided on the load-bearing ring 103 to facilitate the insertion of the fastening bolt 204d, so as to further ensure the stability of the shift block 204b. When it is necessary to process nuts of different sizes, the fastening bolt 204d is first rotated so that the shift block 204b can be shifted, and then the shift block 204b is shifted so that the ring 203a rotates counterclockwise, so that the smaller trapezoidal block 203b is opposite to the insertion rod 202g. At this time, under the action of the first spring 202d, the slider 202c is reset. The insertion rod 202g is reset and disengaged from the installation opening 202f, so that the replacement mold 104 can be taken out, and then a larger replacement mold 104 can be replaced (the same applies to a smaller replacement mold 104). After the replacement mold 104 is placed on the curved plate, the installation opening 202f on the replacement mold 104 is aligned with the insertion rod 202g, and then the shift block 204b is moved to make the ring 203a rotate, so that the trapezoidal block 203b is aligned with the insertion rod 202g. The setting of the cutting edge 203c avoids the trapezoidal block 203b and the insertion rod 202g from getting stuck. The reference line 204c is set here, and the shift block 204b can be moved to the required position according to the size of the replacement mold 104, thereby ensuring that the installation opening 202f can cooperate with the insertion rod 202g. When multiple insertion rods 202g are inserted into the installation opening 202f of the replacement mold 104, the replacement mold 104 is fixed.

[0033] In summary, by setting up a replacement mold 104 and a switching component 200, the processing of nuts of different sizes can be adapted by replacing the replacement mold 104, so there is no need to disassemble the entire lower mold 102, which is more convenient to use. When replacing the replacement mold 104, only the shift block 204b needs to be turned to loosen and tighten the replacement mold 104, which is convenient to operate.

[0034] Example 2, reference Figure 1-Figure 5, which is the second embodiment of the present invention. Different from the previous embodiment, this embodiment provides an adjustment component 300 of a fastener stamping die with a fine-tunable die punch, which solves the problem of how to adjust the position of the fan-shaped block 201b so that it will not block the punching of the punch body 105 while ensuring support. It includes a guide assembly 301, including a connecting plate 301a fixedly connected to the shift block 204b, a support ring 301b fixedly connected to the connecting plate 301a, and a plurality of arc grooves 301c are provided on the support ring 301b; a pulling assembly 302 includes a guide opening 302a passing through the load-bearing ring 103, an L-shaped rod 302b is slidably connected in the guide opening 302a, the L-shaped rod 302b cooperates with the arc groove 301c, and the L-shaped rod 302b is fixedly connected to the side wall of the fan-shaped block 201b.

[0035] Specifically, when replacing a different replacement mold 104, the punch body 105 thereon also needs to be replaced. Since when the nut becomes larger, the diameter of its inner ring will also become larger, and thus a larger punch body 105 is required (similarly when the nut becomes smaller, the punch body 105 becomes smaller). After the nut becomes larger, although the sector block 201b can also provide support, since the diameter of the circle formed by the inner ring of the sector block 201b is smaller, the punch body 105 will collide with the arc block, and thus the position of the sector block 201b needs to be changed.

[0036] When in use, when the shift block 204b is shifted, the connecting plate 301a is also driven to move, thereby driving the support ring 301b to rotate. When the support ring 301b rotates, the arc groove 301c can cooperate with the L-shaped rod 302b, thereby driving the fan-shaped block 201b to move inward or outward, so that the positions of multiple fan-shaped blocks 201b are changed to avoid collision with the punch body 105. The distance between the arc groove 301c and the side wall of the supporting ring 103 here gradually increases counterclockwise with the support ring 301b. It is worth noting that when removing the replacement mold 104, it is necessary to hold the replacement mold 104 by hand to avoid the situation where the fan-shaped block 201b moves outward a large distance when the shift block 204b is shifted, causing the insertion rod 202g to leave the installation port 202f, and the replacement mold 104 falls into the supporting ring 103.

[0037] In summary, by setting the adjustment component 300, when the shift block 204b is moved to fix the replacement mold 104 after replacement, the multiple fan-shaped blocks 201b can also be driven to move, thereby adjusting the diameter of the circle formed by the inner circles of the six fan-shaped blocks 201b, while ensuring that the replacement mold 104 is supported, the punching of the punch body 105 will not be blocked.

[0038] Example 3, reference Figure 1-Figure 6, which is the third embodiment of the present invention. Different from the previous embodiment, this embodiment provides a lifting component 400 of a fastener stamping die with a fine-adjustable die punch, which solves the problem of how to place nuts of different thicknesses. It includes a sliding assembly 401, including a lifting plate 401a slidably connected to the fan-shaped groove 201a, a sliding groove 401b is provided on the lifting plate 401a, a moving block 401c is slidably connected in the sliding groove 401b, and the moving block 401c is fixedly connected to the bottom of the fan-shaped block 201b. The threaded assembly 402 includes a rotating shaft 402a rotatably connected to the bottom of the fan-shaped groove 201a, and a threaded rod 40 is fixedly connected to the rotating shaft 402a. 2b, a threaded sleeve 402c is threadedly connected to the threaded rod 402b, and the threaded sleeve 402c is fixedly connected to the bottom of the lifting plate 401a; the gear assembly 403 includes a gear 403a fixedly connected to the rotating shaft 402a, an annular opening 403b is provided on the fan-shaped groove 201a, a gear ring 403c meshing with the gear 403a is provided in the annular opening 403b, a second arc-shaped opening 403d with a width smaller than the thickness of the gear ring 403c is provided on the side wall of the load-bearing ring 103, a lever 403e fixed to the gear ring 403c is slidably connected in the second arc-shaped opening 403d, and a reference line 403f is provided on the side wall of the load-bearing ring 103 and on the lever 403e.

[0039] Specifically, the width of the second arc-shaped opening 403d here is smaller than the width of the gear ring 403c, so as to prevent the gear ring 403c from being separated from the second arc-shaped opening 403d, and ensure the stability of the movement of the gear ring 403c (the first arc-shaped opening 204a is the same, in order to ensure the stability of the rotation of the ring 203a), and the lifting plate 401a here is completely in the fan-shaped groove 201a, so as not to collide with the punch body 105, and the gear ring 403c here is meshed with multiple gears 403a, so as to allow six fan-shaped blocks 201b to move upward at the same time, avoiding the phenomenon of inconsistent height of any fan-shaped block 201b, and the slide groove 401b and the moving block 401c here are both T-shaped, so as to prevent the fan-shaped block 201b from being separated from the lifting plate 401a.

[0040] During use, when it is necessary to process nuts of different thicknesses, it is necessary to adjust the height of the arc block. At the same time, when the nut is thicker, its installation port 202f is at the upper end of the nut, so there is no need to adjust the position of the insertion rod 202g. When making adjustments, it is only necessary to move the lever 403e to rotate the gear ring 403c, thereby driving the gear 403a to rotate, causing the rotating shaft 402a to rotate, and then the threaded rod 402b to rotate, driving the threaded sleeve 402c to move downward, causing the lifting plate 401a to move downward. A plurality of reference lines 403f are set on the side wall of the load-bearing ring 103, and the plurality of reference lines 403f correspond to nuts of different thicknesses respectively. The lever 403e can be moved according to the reference lines 403f, and damping is set on the rotating shaft 402a to prevent the threaded rod 402b from self-rotating, thereby ensuring the height stability of the lifting plate 401a.

[0041] In summary, by setting the lifting component 400, the lifting plate 401a can be lifted and lowered by toggling the lever 403e, so that the fan-shaped block 201b can be lifted and lowered, thereby being suitable for nuts of different thicknesses and having a wider range of uses.

[0042] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
