Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skilled in the art without creative labor are within the protection scope of the utility model.

[0031] Please refer to Figures 1-6 The utility model discloses an embodiment, propose a kind of punch position adjustable stamping die, including mutually stamping cooperation's upper die main body 10 and lower die main body 20, upper die main body 10 is provided with upper backing plate 11, fixedly connected on upper backing plate 11 upper blank holder 12, and slidingly connected on upper backing plate 11 male die fixing plate 13, on male die fixing plate 13 inlay setting has the male die cutter 14 for stamping workpiece;Male die fixing plate 13 is provided with first locking mechanism 30, and upper backing plate 11 is provided with multiple first detent groove 15 corresponding to first locking mechanism 30, male die fixing plate 13 is adjusted position by with upper backing plate 11 slidingly cooperated, male die fixing plate 13 is fixed by the clamping of first locking mechanism 30 and first detent groove 15;

[0032] Lower die main body 20 is provided with lower backing plate 21, fixedly connected on lower backing plate 21 lower blank holder 22, and slidingly connected on lower backing plate 21 female die fixing plate 23, on female die fixing plate 23 inlay setting has the female die cutter 24 for stamping workpiece;Female die fixing plate 23 is provided with second locking mechanism 40, and lower backing plate 21 is provided with multiple second detent groove 25 corresponding to second locking mechanism 40, female die fixing plate 23 is adjusted position by with lower backing plate 21 slidingly cooperated, female die fixing plate 23 is fixed by the clamping of second locking mechanism 40 and second detent groove 25;

[0033] Among them, upper blank holder 12 and lower blank holder 22 are mutually matched for being pressed to workpiece, male die cutter 14 and female die cutter 24 are mutually matched for being stamping to workpiece.

[0034] In the above technical solution, the punch fixed plate 13 can adjust the position under the sliding cooperation with the upper die plate 11, the first locking mechanism 30 arranged on the punch fixed plate 13 can be clamped and cooperated with the corresponding first detent slot 15 on the upper die plate 11 to realize the fixation, when the position of the punch die 14 needs to be adjusted, the first locking mechanism 30 is loosened first, so that the punch fixed plate 13 can slide along the upper die plate 11 to the required position, and then the first locking mechanism 30 is clamped with the corresponding first detent slot 15 to fix the punch fixed plate 13, so as to determine the new position of the punch die 14. The die fixed plate 23 can also adjust the position through the sliding cooperation with the lower die plate 21, the second locking mechanism 40 arranged on the die fixed plate 23 can be clamped and cooperated with the corresponding second detent slot 25 on the lower die plate 21 to realize the fixation, when the position of the die punch 24 needs to be adjusted, the second locking mechanism 40 is unlocked first, so that the die fixed plate 23 can slide on the lower die plate 21 to the appropriate position, and then the second locking mechanism 40 is clamped with the corresponding second detent slot 25 to fix the die fixed plate 23, so as to determine the new position of the die punch 24.

[0035] The upper pressure plate 12 cooperates with the lower pressure plate 22 during the stamping process to press the workpiece, so that the workpiece can maintain a stable state during the stamping of the punch die 14.

[0036] Therefore, for those products with only slight differences in size or slight changes in processing position, it is no longer necessary to replace the punch fixed plate 13, the punch die, the die fixed plate 23, the die, and other components as in the traditional die, but only to adjust the positions of the punch fixed plate 13 and the die fixed plate 23, so that the die can adapt to the processing needs of different products, greatly improving the versatility of the die and making it better cope with diversified production needs.

[0037] When the traditional die needs to adjust the die structure to face the product change, the replacement of the related components not only consumes time and effort, but also generates labor cost and material cost, while the position-adjustable stamping die only needs to be adjusted and locked, without the need to replace a large number of components, effectively saving the time spent on adjusting the die, reducing the labor and material costs, and thus improving the production efficiency.

[0038] Since the positions of the punch die 14 and the die punch 24 can be accurately adjusted and fixed by the locking mechanism, the relative position accuracy of the two can be better guaranteed during the stamping process, thereby ensuring the processing accuracy of the workpiece and helping to produce higher quality products.

[0039] Please refer to Figures 5-6The utility model technical scheme, propose first locking mechanism 30 and second locking mechanism 40 all include knob adjusting part 50, adjusting push rod 61 connected on knob adjusting part 50, slope push slide 62 set on adjusting push rod 61, and with the slope push slide 62 carry out slope abutment cooperation's slope clamping slide 63, the knob adjusting part 50 of first locking mechanism 30 is set on the male die fixed plate 13, the knob adjusting part 50 of second locking mechanism 40 is set on the female die fixed plate 23, and in male die fixed plate 13 and female die fixed plate 23 inside all are provided with the right angle slide groove 64 through its back and side, adjusting push rod 61 is driven by adjusting knob to drive slope push slide 62;

[0040] Slope clamping slide 63 and slope push slide 62 are slidably connected at both ends of right angle slide groove 64, and realize slope abutment cooperation in right angle slide groove 64, and first compression spring 65 for bearing against slope clamping slide 63 is also set in right angle slide groove 64, one end of slope clamping slide 63 is stretched out in right angle slide groove 64 and is clamped into first detent slot 15 or second detent slot 25 by the elastic force of first compression spring 65, and one end of slope clamping slide 63 is driven by the slope abutment of slope push slide 62 and is separated from first detent slot 15 or second detent slot 25 by overcoming the elastic force of first compression spring 65.

[0041] By the rotation of knob adjusting part 50, adjusting push rod 61 is moved, and then makes slope push slide 62 slide in right angle slide groove 64, and slope push slide 62 and slope clamping slide 63 realize force transmission and conversion by slope abutment cooperation. Meanwhile, by the elastic force of first compression spring 65, slope clamping slide 63 keeps the state of stretching out in normal state, to realize the clamping with first detent slot 15 or second detent slot 25.

[0042] When it is needed to fix male die fixed plate 13 or female die fixed plate 23 at corresponding position, for example, male die fixed plate 13 is fixed at a detent slot of upper pad plate 11, by rotating knob adjusting part 50 of first locking mechanism 30. Knob adjusting part 50 drives adjusting push rod 61 to move, and adjusting push rod 61 pushes slope push slide 62 to slide in right angle slide groove 64.

[0043] Because of the slope abutment relation of slope push slide 62 and slope clamping slide 63, slope push slide 62 will exert a thrust on slope clamping slide 63, so that slope clamping slide 63 slides to the inside of right angle slide groove 64 by overcoming the elastic force of first compression spring 65, until the slope of slope push slide 62 moves to the appropriate position, at this time, one end of slope clamping slide 63 is stretched out in right angle slide groove 64 and clamped into corresponding first detent slot 15 or second detent slot 25 under the elastic force of first compression spring 65, thereby realizing the fixation of male die fixed plate 13 or female die fixed plate 23.

[0044] When it is necessary to adjust the position of the punch fixing plate 13 or the die fixing plate 23, that is, to release the fixed state, the knob adjusting part 50 of the first locking mechanism 30 or the second locking mechanism 40 is rotated in the opposite direction. The knob adjusting part 50 drives the adjusting push rod 61 to move in the opposite direction, the adjusting push rod 61 drives the inclined surface pushing block 62 to slide in the opposite direction, and the inclined surface pushing block 62 again applies a pushing force to the inclined surface clamping block 63 through the inclined surface, which is opposite to the previous pushing force. The inclined surface clamping block 63 further overcomes the elastic force of the first compression spring 65 and slides into the straight slot 64 until one end of the inclined surface clamping block 63 is completely separated from the first stop slot 15 or the second stop slot 25. At this time, the punch fixing plate 13 or the die fixing plate 23 can be freely adjusted in position.

[0045] The design of the first locking mechanism 30 and the second locking mechanism 40 realizes reliable fixing and convenient unlocking of the punch fixing plate 13 and the die fixing plate 23 after adjusting the position through the ingenious inclined surface cooperation and spring elastic force, and further improves the practicability and flexibility of the punch position adjustable stamping die.

[0046] Please refer to Figures 5-6 In the technical scheme of the utility model, the knob adjusting part 50 comprises a threaded rod 51 fixedly connected to the side of the punch fixing plate 13 or the die fixing plate 23, a knob main body 52 threadedly connected to the threaded rod 51, and a second compression spring 53 sleeved on the threaded rod 51. The adjusting push rod 61 is movably arranged on the threaded rod 51 and abuts against the knob main body 52 and the second compression spring 53.

[0047] The adjusting push rod 61 is movably provided on the threaded rod 51, and is tightly connected between the knob body 52 and the second compression spring 53. This connection mode makes it possible for the knob body 52 to directly push or pull the adjusting push rod 61 when it rotates and moves axially along the threaded rod 51. Specifically, the axial movement of the knob body 52 during rotation will transmit force to the adjusting push rod 61 through the tight relationship with the adjusting push rod 61, thereby driving the adjusting push rod 61 to move accordingly, and then realizing the subsequent movement of components such as the inclined surface pushing the slider 62, and finally completing the locking or unlocking operation of the punch fixing plate 13 or the die fixing plate 23. In the initial state, the second compression spring 53 is in a certain compression state, and it applies an elastic force to both the knob body 52 and the adjusting push rod 61. When the knob body 52 rotates and moves in a certain direction, the second compression spring 53 will be further compressed or gradually relax, depending on the movement direction of the knob body 52. ​​For example, during the unlocking process, the knob body 52 moves in the direction away from the adjusting push rod 61, and the second compression spring 53 will be further compressed. At the same time, its elastic force will have a certain hindering effect on the knob body 52, so that the movement of the knob body 52 will not be too rapid, thereby ensuring the smoothness of the adjustment process. During the locking process, the knob body 52 moves in the direction close to the adjusting push rod 61, and the second compression spring 53 will gradually relax. Its elastic force will assist the knob body 52 in pushing the adjusting push rod 61, which helps to complete the locking operation more accurately.

[0048] Therefore, the structural design of the knob adjustment member 50 achieves effective control of the adjustment push rod 61 through reasonable component connection and clever use of the elastic force of the second compression spring 53, thereby providing a reliable adjustment means for the normal operation of the entire first locking mechanism 30 and the second locking mechanism 40, ensuring the flexibility and stability of the stamping die with adjustable punch position during use.

[0049] See also Figure 1 In the technical solution of the present utility model, it is proposed that two inclined-surface push sliders 62 and inclined-surface clamping sliders 63 of the first locking mechanism 30 and the second locking mechanism 40 are provided, and two right-angle slide grooves 64 and first compression springs 65 are provided accordingly, wherein the two inclined-surface push sliders 62 are respectively fixedly connected to the two ends of the adjusting push rod 61, and the threaded rod 51 is passed through the middle of the adjusting push rod 61; this paired arrangement can effectively improve the stability, reliability and smoothness of the mold during the locking and unlocking process, and further optimize the performance of the stamping mold with adjustable punch position.

[0050] See also Figure 1The utility model technical scheme, propose that both sides of upper bolster plate 11 and lower bolster plate 21 set up limit sliding slot 70, both sides of male die fixed plate 13 and female die fixed plate 23 set up slide strip 80, male die fixed plate 13 is connected in sliding on upper bolster plate 11 through the cooperation of slide strip 80 and limit sliding slot 70, female die fixed plate 23 is connected in sliding on lower bolster plate 21 through the cooperation of slide strip 80 and limit sliding slot 70.

[0051] The cooperation of slide strip 80 and limit sliding slot 70 provides clear guidance for the sliding of male die fixed plate 13 and female die fixed plate 23 on the bolster plate, and during the adjustment of the positions of male die fixed plate 13 and female die fixed plate 23, slide strip 80 slides along limit sliding slot 70, which can ensure that the moving directions of male die fixed plate 13 and female die fixed plate 23 always remain consistent and accurate, avoiding unstable conditions such as deviation or shaking during sliding, thereby ensuring the working accuracy of the stamping die under different position adjustments

[0052] Limit sliding slot 70 limits slide strip 80, which indirectly limits the sliding range of male die fixed plate 13 and female die fixed plate 23, and appropriate limiting structures can be specially provided to further limit the sliding stroke of male die fixed plate 13 and female die fixed plate 23, which ensures that they do not exceed the pre-set reasonable range during position adjustment, preventing problems such as die structure damage or failure to work normally due to excessive sliding, and further ensuring the normal use and service life of the die.

[0053] This structure design of setting limit sliding slot 70 on upper bolster plate 11 and lower bolster plate 21, and setting slide strip 80 on male die fixed plate 13 and female die fixed plate 23 and cooperating with each other effectively improves the accuracy, stability and protection of the overall die structure during the position adjustment process of the stamping die with adjustable punch position, laying a solid foundation for the die to better adapt to diversified production needs.

[0054] Please refer to Figures 2-4 The utility model technical scheme, propose that male die fixed plate 13 and female die fixed plate 23 set up two, two male die fixed plate 13 correspond respectively at the both sides of upper pressure plate 12, two female die fixed plate 23 correspond respectively at the both sides of lower pressure plate 22.This setting mode of double male die fixed plate 13 and double female die fixed plate 23 can provide more adjustment possibilities when facing workpieces of different sizes, shapes or processing requirements, and for some workpieces with complex shapes or requiring special stamping process, the positions of male die cutter 14 and female die cutter 24 on the two male die fixed plate 13 and the two female die fixed plate 23 can be adjusted respectively to better adapt to the processing needs of the workpiece, thereby improving the versatility of the die and enabling it to be more widely applied to diversified production scenarios.

[0055] Please refer to Figure 2The utility model technical scheme, propose in the male die fixed plate 13 on the position department close to upper pressing plate 12 set up for the pre -pressing block 16 that workpiece is pressed in female die fixed plate 23 in advance, wherein, set up in male die fixed plate 13 inside pre -pressing limit slot 17, pre -pressing block 16 is movably connected in pre -pressing limit slot 17, pre -pressing spring 18 is arranged between the upper end of pre -pressing block 16 and the inside of pre -pressing limit slot 17, and pre -pressing block 16 lower end is through pre -pressing spring 18 to the workpiece with punching and cutting exert pre -pressing force.

[0056] When the mould starts to work, before male die fixed plate 13 is not completely pressed down to carry out formal stamping, because pre -pressing block 16 lower end is contacted with workpiece, with the gradual down pressure of male die fixed plate 13, pre -pressing block 16 will move upwards in pre -pressing limit slot 17, at this time, pre -pressing spring 18 is compressed, and the elastic potential energy is stored, when male die fixed plate 13 continues to press down to a certain degree, pre -pressing block 16 lower end will exert pre -pressing force to the workpiece with punching and cutting under the action of the elastic force of pre -pressing spring 18, and workpiece is pressed in female die fixed plate 23 in advance.

[0057] The pre -pressing force of pre -pressing block 16 to workpiece can make workpiece be in a pre -deformation state before stamping, so that in the subsequent formal stamping process, when male die cutter 14 and female die cutter 24 stamp workpiece, workpiece can more evenly bear pressure, reduce the situation of partial deformation too large or uneven, and then improve the stamping effect and improve the quality of workpiece after stamping.

[0058] Please refer to Figures 3-4The utility model technical scheme, still be provided with guide column 19 on male die fixed plate 13, the female die fixed plate 26 of being provided with the guide sleeve of butt joint in guide column 19 on 23, make male die fixed plate 13 and female die fixed plate 23 in the process of adjusting position through the cooperation of guide column 19 and guide sleeve 26 keep in step. In the process of adjusting position of male die fixed plate 13 and female die fixed plate 23, the cooperation of guide column 19 and guide sleeve 26 plays a vital role, when male die fixed plate 13 moves, the guide column 19 on it will move together, and guide column 19 will be inserted into the guide sleeve 26 on female die fixed plate 23, because of the guide and restriction of guide sleeve 26 to guide column 19, make male die fixed plate 13 and female die fixed plate 23 can keep in step in the movement process, that is, their moving direction, speed etc. can keep consistent, avoid the die structure deformation, stamping precision decline etc. caused by the inconsistent movement of both. By keeping in step and improving the adjustment precision, the cooperation of guide column 19 and guide sleeve 26 further enhances the overall stability of the die, in the stamping process, stable die structure is crucial to guarantee the stamping quality and die service life, this cooperation mode makes male die fixed plate 13 and female die fixed plate 23 in the working process of entire stamping die, whether in the adjustment position stage or in the subsequent stamping operation stage, can keep good stability, thereby ensure the smooth progress of stamping work and the stable output of product quality.

[0059] It will be apparent to those skilled in the art that the utility model is not limited to the details of the above-exemplified embodiments, but that the utility model can be implemented in other concrete forms without departing from the spirit or essential characteristics of the utility model.
