Description

Technical Field

[0001] The present application relates to the field of stamping dies, and in particular to a punch structure and a stamping die. Background Art

[0002] The punch is a crucial component of a stamping die. Its function is to contact the product being stamped, applying force to it and causing it to bend. By adjusting the position of the punch relative to the upper die of the die, the amount of deformation of the product can be adjusted.

[0003] When a product to be stamped has multiple parts to be stamped, the die used to stamp the product is generally equipped with multiple punches so that the multiple parts to be stamped on the product can be stamped simultaneously to improve the stamping efficiency of the product. However, when the deformation of multiple stamped parts of the product needs to be adjusted, the position of each punch needs to be adjusted in turn, which takes a lot of time and results in low efficiency of punch position adjustment. Utility Model Content

[0004] In view of this, the present application provides a punch structure that can quickly adjust the positions of multiple punches.

[0005] An embodiment of the present application provides a punch structure, comprising a mounting seat, a plurality of punches, a plurality of drive rods, a sliding seat, a first adjustment mechanism, and a plurality of second adjustment mechanisms. A plurality of punches are slidably arranged on the mounting seat along a first direction. A plurality of drive rods are slidably arranged on the mounting seat along a second direction, and each drive rod is configured to correspond to a punch. The sliding seat is slidably arranged on the mounting seat along the second direction. The first adjustment mechanism connects the sliding seat and the mounting seat, and the first adjustment mechanism is configured to drive the sliding seat to move along the second direction. A plurality of second adjustment mechanisms connect the sliding seat and the drive rod, and each second adjustment mechanism is configured to drive a drive rod to move along the second direction, so that the drive rod pushes against the corresponding punch, causing the punch to slide relative to the mounting seat along the first direction.

[0006] In the above embodiment, when the first adjustment mechanism drives the sliding seat to move in the positive second direction, the plurality of second adjustment mechanisms drive the corresponding plurality of drive rods to move synchronously in the positive second direction, thereby causing the drive rods to push against the punches, causing the corresponding plurality of punches to move synchronously in the positive first direction. Each second adjustment mechanism is then sequentially operated to further adjust the position of each drive rod relative to the sliding seat in the second direction. When the drive rods further move relative to the sliding seat in the positive second direction, the punches can further move in the positive first direction. When the drive rods further move relative to the sliding seat in the negative second direction, the punches can move in the negative first direction under their own weight or other external forces. This allows the position of each punch to be further adjusted after the sliding seat is fixed, allowing each punch to be moved to a desired position. This punch structure allows the positions of the plurality of punches to be synchronously adjusted first by the first adjustment mechanism, and then further adjusted by each second adjustment mechanism. This reduces the total time required to adjust the position of each punch, thereby achieving the effect of rapidly adjusting the positions of the plurality of punches.

[0007] In some embodiments of the present application, the second adjustment mechanism includes a rotating member rotatably mounted on a sliding seat, the rotating member being provided with a driving portion. In a direction opposite to the rotation direction of the rotating member, the distance between the driving portion and the rotating axis of the rotating member, along the radial direction of the rotating axis of the rotating member, gradually increases. The driving rod is provided with a mating portion, and the driving portion abuts the mating portion to drive the corresponding driving rod.

[0008] In the above embodiment, since the distance between the driving portion and the rotational axis of the rotating member gradually increases in the direction opposite to the rotational direction of the rotating member, when the rotating member rotates in the forward direction, the distance between the engaging portion and the rotational axis of the rotating member gradually increases, thereby causing the driving rod to move away from the rotating member in the forward direction of the second direction to push against the punch, causing the punch to move in the forward direction of the first direction. When the rotating member rotates in the reverse direction, the distance between the engaging portion and the rotational axis of the driving rod decreases, allowing the driving rod to approach the rotating member in the reverse direction of the second direction, thereby causing the punch to move in the reverse direction of the first direction.

[0009] In some embodiments of the present application, the rotating member is an eccentric ratchet, which includes a plurality of continuously arranged tooth grooves, and the plurality of continuously arranged tooth grooves form a driving portion. The mating portion is provided with a convex tooth, and the convex tooth is configured to abut against an inner wall of at least one tooth groove.

[0010] In the above embodiment, rotating the eccentric ratchet sequentially aligns tooth grooves at different positions with the protruding teeth. As the protruding teeth are inserted into different tooth grooves, the distance between the protruding teeth and the rotation axis of the eccentric ratchet changes, causing the position of the drive rod to change, thereby adjusting the position of the punch. The protruding teeth are inserted into the tooth grooves and abut against the inner walls of the tooth grooves, which can limit the rotation of the eccentric ratchet to a certain extent, thereby improving the stability of the eccentric ratchet and the stability of the drive rod after adjustment.

[0011] In some embodiments, the end of the convex tooth is inclined relative to the second direction, and / or the tooth groove opening is inclined relative to the second direction, so that when the rotating member rotates forward and reverse, the inner wall of the tooth groove has a driving force on the convex tooth to move the convex tooth toward the outside of the corresponding tooth groove.

[0012] In the above embodiment, since the inner wall of the tooth groove or the side wall of the protruding tooth is inclined relative to the second direction, when the eccentric ratchet is rotated with force, the inner wall of the tooth groove pushes the protruding tooth, so that the protruding tooth is subjected to a force along the second direction and away from the eccentric ratchet, thereby causing the protruding tooth to disengage from the current tooth groove; when another tooth groove is aligned with the protruding tooth as the eccentric ratchet rotates, the protruding tooth can be inserted into the corresponding tooth groove and remain in contact with the inner wall of the tooth groove.

[0013] In some embodiments of the present application, the second adjustment mechanism further includes an elastic component, which is disposed on the sliding seat and connected to the corresponding driving rod to provide an elastic force to the corresponding driving rod to cause the corresponding mating portion to abut against the driving portion.

[0014] In the above embodiment, the elastic component has an elastic force on the driving rod to keep the matching portion and the driving portion in contact, so that the driving rod can automatically reset in the opposite direction of the second direction, so that the punch can reset in the opposite direction of the first direction.

[0015] In some embodiments of the present application, the elastic assembly includes an abutment column, an abutment rod, and a reset elastic member. The abutment column is slidably disposed on the sliding seat along the second direction. The abutment rod protrudes from the end wall of one end of the abutment column along the second direction, and the end of the abutment rod away from the abutment column is configured to be connected to the drive rod. The reset elastic member is disposed on the sliding seat and connected to the abutment column. The reset elastic member exerts an elastic force on the abutment column along the second direction, so that the abutment rod exerts an elastic force on the drive rod to move the drive rod toward the driving portion.

[0016] In the above embodiment, the elastic force of the reset elastic member is transmitted to the corresponding driving rod in turn through the abutment column and the abutment rod. Compared with the reset elastic member and the abutment column, the cross-sectional area of ​​the abutment rod perpendicular to the second direction is smaller. When the distance between two adjacent driving rods is small, the possibility of the abutment rod contacting and interfering with another driving rod can be reduced.

[0017] In some embodiments of the present application, the elastic component also includes a swing arm, which is rotatably arranged on a sliding seat. The swing arm has a first end and a second end, and the first end and the second end are respectively located on both sides of the rotation axis of the swing arm. The second end is connected to the driving rod, and the abutment rod is connected to the first end.

[0018] In the above embodiment, by setting a swing arm, the reset elastic member, the abutment column and the abutment rod can all be located on one side of the driving rod along a direction perpendicular to the second direction, so that the reset elastic member, the abutment column and the abutment rod are away from the sliding path of the driving rod, which can increase the installation space of the reset elastic member, the abutment column and the abutment rod, thereby facilitating the installation or debugging of the reset elastic member.

[0019] In some embodiments of the present application, the punch structure also includes a reset member, which is arranged on the mounting seat and is configured to provide a force to each punch along a first direction and toward the corresponding drive rod, so that each punch remains in contact with the corresponding drive rod.

[0020] In the above embodiment, the reset member can keep each punch in contact with the corresponding driving rod, which can improve the accuracy of the position of the punch changing with the position of the driving rod, thereby improving the accuracy of the punch position adjustment.

[0021] In some embodiments of the present application, the driving rod is provided with a driving surface for pushing against the corresponding punch, and the punch is provided with an abutting surface that contacts the corresponding driving surface. The second direction intersects the first direction, the driving surface is inclined relative to the second direction, and the abutting surface is parallel to the driving surface.

[0022] In the above embodiment, the second direction intersects the first direction, causing the drive rod to be tilted relative to the punch, thereby reducing the size of the punch structure along the first direction. Because the drive surface is tilted relative to the second direction, when the drive surface abuts the abutment surface and moves relative to the abutment surface, the drive surface exerts a force along the first direction on the abutment surface, causing the punch to move along the first direction. The abutment surface is parallel to the drive surface, ensuring full contact between the abutment surface and the drive surface, thereby improving the stability of the contact connection between the drive rod and the punch.

[0023] An embodiment of the present application also provides a stamping die, comprising an upper die, a lower die, and a punch structure provided in any of the above embodiments, wherein the mounting seat of the punch structure is connected to the upper die or the lower die.

[0024] In the above embodiment, the positions of multiple punches can be quickly adjusted to shorten the time for adjusting the stamping die and increase the time the stamping die remains in operation, which is beneficial to improving the efficiency of stamping products with the stamping die.

[0099] The following embodiments of the present application are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features therein may be combined with each other.

[0100] Reference Figure 1 One embodiment of the present application provides a punch structure 100, including a mounting seat 11, a plurality of punches 12, a plurality of driving rods 13, a reset member 14, a sliding seat 15, a first adjustment mechanism 16 and a plurality of second adjustment mechanisms 17.

[0101] Reference Figure 1 and Figure 2 In some embodiments, the mounting base 11 includes a mounting plate 111, a connecting plate 112, and a fixing plate 113. The mounting plate 111 has an installation area 1111 and an operating area 1112. The connecting plate 112 and the fixing plate 113 are sequentially stacked in the installation area 1111 of the mounting plate 111, with the connecting plate 112 located between the fixing plate 113 and the mounting plate 111. The mounting plate 111, the connecting plate 112, and the fixing plate 113 are fixedly connected to each other. In other embodiments, the fixing plate 113, the connecting plate 112, and the mounting plate 111 may also be integrally formed.

[0102] In some embodiments, the stacking direction of the fixing plate 113 and the connecting plate 112 is defined as a first direction X, and the direction from the mounting plate 111 toward the fixing plate 113 is defined as the positive direction of the first direction X. The direction of the line connecting the operating area 1112 and the mounting area 1111 is defined as a second direction Y, and the direction from the operating area 1112 toward the mounting area 1111 is defined as the positive direction of the second direction Y, with the second direction Y being perpendicular to the first direction X. The third direction Z is defined as a direction perpendicular to the first direction X and the second direction Y. In other embodiments, the second direction Y can be defined as a direction inclined relative to the first direction X. In still other embodiments, the second direction Y can be defined as a direction parallel to the first direction X.

[0103] In some embodiments, multiple punches 12 are slidably mounted on the mounting base 11 along a first direction X. A guide hole 1131 is defined along the first direction X on the sidewall of the fixing plate 113 facing away from the connecting plate 112. The guide hole 1131 extends through the sidewall of the fixing plate 113 and faces the connecting plate 112. A guide groove 1121 is defined along the sidewall of the connecting plate 112 facing the operating area 1112 along the second direction Y. The guide groove 1121 extends along the second direction Y and communicates with the guide hole 1131. Multiple punches 12 are sequentially arranged along a third direction Z, each inserted into and extending into the guide hole 1131. The ends of the punches 12 facing away from the guide groove 1121 protrude from the outside of the guide hole 1131 to engage the product to be processed. The peripheral wall of each punch 12 is in contact with the inner wall of the guide hole 1131, allowing the punches 12 to slide relative to the mounting plate 111 along the first direction X. In other embodiments, multiple punches 12 can be dispersedly arranged. It can be understood that the fixing plate 113 has multiple guide holes 1131 and the connecting plate 112 has multiple guide grooves 1121 correspondingly. Each punch 12 is inserted into a guide hole 1131 and extends into a corresponding guide groove 1121.

[0104] In other embodiments, the punch 12 may also be slidably connected to the mounting seat 11 along the first direction X via a slide rail or other structures.

[0105] In some embodiments, an end wall of each punch 12 adjacent to the guide groove 1121 is provided with an abutting surface 121 .

[0106] In some embodiments, a plurality of drive rods 13 are slidably arranged on the mounting base 11 along the second direction Y, and each drive rod 13 is configured to correspond to a punch 12. One end of the plurality of drive rods 13 is inserted into the guide groove 1121, and the other end extends to the operating area 1112. The peripheral wall of each drive rod 13 is in contact with the inner wall of the guide groove 1121, and the drive rod 13 can slide relative to the mounting plate 111 along the second direction Y. In some embodiments, a drive surface 131 is provided at one end of each drive rod 13 close to the guide groove 1121, and the drive surface 131 is located on the side wall of the drive rod 13 along the first direction X and facing the corresponding punch 12, and the drive surface 131 abuts against the abutment surface 121 of the corresponding punch 12.

[0107] In other embodiments, the driving rod 13 may also be slidably connected to the mounting base 11 along the second direction Y through a slide rail or other structure.

[0108] In some embodiments, the reset member 14 is disposed on the mounting seat 11 , and the reset member 14 is configured to provide a force to each punch 12 along the first direction X and toward the driving surface 131 of the corresponding driving rod 13 .

[0109] In some embodiments, each punch 12 is provided with an abutting groove 122 , which passes through a side wall of the punch 12 along one side of the second direction Y. The reset member 14 is inserted into the abutting groove 122 to connect with the punch 12 .

[0110] In some embodiments, the reset member 14 is comb-shaped and has a plurality of elastic pieces 141. The main body of the reset member 14 is fixedly connected to the fixing plate 113 by screws. Each elastic piece 141 corresponds to a punch 12, and each elastic piece 141 is inserted into the corresponding abutment groove 122 and abuts against the inner wall of the abutment groove 122 along the first direction X and close to the abutment surface 121. Each elastic piece 141 has an elastic force in the opposite direction of the first direction X on the inner wall of the corresponding abutment groove 122, so that the abutment surface 121 of the corresponding punch 12 remains in abutment with the driving surface 131. In other embodiments, the reset member 14 may also include a plurality of springs or a plurality of other elastic structural members. In other embodiments, the reset member 14 may also be a fixed structure for maintaining the abutment between the punch 12 and the drive rod 13. For example, the reset member 14 may be a plurality of abutment bolts threadedly connected to the fixing plate 113. After the position of the drive rod 13 is adjusted, the abutment bolts are rotated to tighten against the inner wall of the abutment groove 122, so that the abutment surface 121 maintains abutment with the drive surface 131. In other embodiments, the reset member 14 may also be connected to the connecting plate 112 or the mounting plate 111.

[0111] In other embodiments, the reset member 14 may be omitted, and the reset member 14 may keep the abutment surface 121 and the driving surface 131 in abutment by its own gravity, or, when stamping the product, the reset member 14 may keep the abutment surface 121 and the driving surface 131 in abutment under the action of the reverse force of the product.

[0112] In some embodiments, the sliding seat 15 is slidably disposed on the mounting seat 11 along the second direction Y. The first adjustment mechanism 16 connects the sliding seat 15 and the mounting seat 11 and is configured to drive the sliding seat 15 to move along the second direction Y. The second adjustment mechanism 17 connects the sliding seat 15 and the drive rod 13, and each second adjustment mechanism 17 is configured to drive a drive rod 13 to move along the second direction Y so that the drive surface 131 of the drive rod 13 pushes against the corresponding abutment surface 121. It can be understood that the sliding seat 15 and the first adjustment mechanism 16 are both disposed in the operating area 1112, and the sliding seat 15 is slidably connected to the mounting plate 111 along the second direction Y, and the first adjustment mechanism 16 connects the sliding seat 15 and the mounting plate 111.

[0113] In some embodiments, the driving surface 131 is inclined relative to the second direction Y, and the abutting surface 121 is parallel to the driving surface 131. In some embodiments, the driving surface 131 extends in the positive direction of the second direction Y and is inclined in the opposite direction of the first direction X. When the sliding seat 15 is driven to move in the positive direction of the second direction Y by the first adjustment mechanism 16, the plurality of second adjustment mechanisms 17 drive the corresponding plurality of driving rods 13 to move synchronously in the positive direction of the second direction Y, thereby causing the driving surface 131 to push against the abutting surface 121, thereby causing the corresponding plurality of punches 12 to move synchronously in the positive direction of the first direction X relative to the mounting seat 11. In some embodiments, when the punch 12 moves synchronously relative to the mounting seat 11 in the positive direction of the first direction X, the elastic sheet 141 of the reset member 14 undergoes elastic deformation; when the first adjustment mechanism 16 drives the sliding seat 15 to move in the reverse direction of the second direction Y, under the elastic action of the elastic sheet 141, the abutment surface 121 pushes the driving surface 131, so that the driving rod 13 can be subjected to the reverse force of the abutment surface 121 along the second direction Y, so as to prompt the driving rod 13 to move relative to the mounting seat 11 in the reverse direction of the second direction Y, so that the punch 12 can be moved relative to the mounting seat 11 in the reverse direction of the first direction X, thereby realizing the preliminary adjustment of the positions of multiple punches 12.

[0114] Then, by operating each second adjustment mechanism 17 in sequence, the second adjustment mechanism 17 drives the corresponding driving rod 13 to move in the forward or reverse direction of the second direction Y, so that the position of each punch 12 can be further adjusted to achieve precise adjustment of the position of each punch 12.

[0115] In other embodiments, the driving surface 131 may also extend in the opposite direction of the second direction Y and tilt in the opposite direction of the first direction X. In this case, when the driving rod 13 moves in the opposite direction, the driving surface 131 pushes the abutting surface 121, so that the punch 12 moves relative to the mounting seat 11 in the positive direction of the first direction X. When the driving rod 13 moves in the positive direction, the abutting surface 121 pushes the driving surface 131, so that the punch 12 moves relative to the mounting seat 11 in the opposite direction of the first direction X.

[0116] In some embodiments, the mounting base 11 further includes a guide block 114, which is fixedly mounted to the operating area 1112 of the mounting plate 111 via bolts. The guide block 114 defines a sliding groove 1141 along the second direction Y. The sliding base 15 includes a sliding frame 151, which is positioned within the sliding groove 1141, with the sidewalls of the sliding frame 151 abutting against the inner wall of the sliding groove 1141. The sliding frame 151 can slide relative to the mounting plate 111 along the second direction Y.

[0117] In some embodiments, the inner walls of both sides of the sliding groove 1141 along its width direction are provided with limiting grooves 1142 along the second direction Y. Limiting bars 1511 are provided on both sides of the sliding frame 151. The limiting bars 1511 are integrally formed with the sliding frame 151, and each limiting bar 1511 is inserted into a limiting groove 1142. The limiting bars 1511 cooperate with the limiting grooves 1142 to constrain the position of the sliding frame 151 relative to the mounting plate 111 along the first direction X.

[0118] In some embodiments, the first adjustment mechanism 16 includes a driving member 161 and a fastener 162, the driving member 161 connects the sliding seat 15 and the mounting seat 11 and is configured to drive the sliding seat 15 to slide, and the fastener 162 is arranged on the sliding seat 15 and is configured to fix the sliding seat 15 relative to the mounting seat 11.

[0119] In some embodiments, the drive member 161 includes an adjustment screw 1611 and a drive head 1612. The drive head 1612 is disposed at one end of the adjustment screw 1611 and is integrally formed with the adjustment screw 1611. The adjustment screw 1611 is rotatably connected to the sliding seat 15 and is threadedly connected to the mounting seat 11. In some embodiments, the sliding seat 15 also includes a sliding block 152. The sliding block 152 is located on the rear side of the guide block 114 in the positive direction of the second direction Y, and the sliding block 152 is integrally formed with the sliding frame 151. The mounting plate 111 is provided with an avoidance groove 1113 along the second direction Y, and the sliding block 152 is slidably engaged with the avoidance groove 1113 along the second direction Y. The sliding block 152 is provided with a mounting hole 1521 along the second direction Y. The avoidance groove 1113 is provided with an adjustment screw hole 1114 on its inner end wall along the second direction Y and near one end of the guide block 114. The adjusting screw 1611 is inserted into the mounting hole 1521 and threadedly connected to the adjusting screw hole 1114 , and the driving head 1612 is configured to abut against the side wall of the sliding block 152 away from the guide block 114 . In other embodiments, the adjusting screw hole 1114 may be provided in the guide block 114 .

[0120] Rotating the adjustment screw 1611 causes the adjustment screw 1611 to move in the positive direction of the second direction Y, causing the drive head 1612 to drive the sliding block 152 and the sliding frame 151 to move synchronously in the positive direction of the second direction Y. When the adjustment screw 1611 moves in the negative direction of the second direction Y, under the elastic action of the elastic piece 141, the drive rod 13 exerts a force on the sliding frame 151 in the negative direction of the second direction Y through the second adjustment mechanism 17, causing the sliding frame 151 to move synchronously with the adjustment screw 1611 in the negative direction of the second direction Y, and maintaining contact between the sliding frame 151 and the drive head 1612. In other embodiments, the adjustment screw 1611 can be rotatably connected to the mounting base 11 and threadedly connected to the sliding base 15.

[0121] In some embodiments, the fastener 162 comprises a fastening screw. In some embodiments, the carriage 151 is provided with a fastening screw hole 1512 extending along the first direction X, and the fastener 162 is threadedly engaged with the fastening screw hole 1512. By rotating the fastener 162, the fastener 162 abuts against the mounting plate 111, restricting movement of the carriage 151 along the second direction Y and thereby securing the carriage 151. By maintaining the fixed position of the carriage 151, the drive rod 13 remains fixed, thereby maintaining the fixed position of the punch 12 and improving the accuracy of adjustment of the position of the punch 12.

[0122] In other embodiments, a through hole may be opened on the sliding frame 151, and a plurality of threaded holes may be opened on the mounting plate 111 in sequence along the second direction Y, so that the fastener 162 is inserted into the through hole on the sliding frame 151 and threadedly engaged with the threaded hole on the mounting plate 111 to achieve the effect of fixing the sliding frame 151.

[0123] In other embodiments, the fastener 162 may also be provided on the mounting base 11 . For example, the fastening screw hole 1512 may be opened on the mounting plate 111 , and the fastener 162 is pressed against the sliding frame 151 to fix the sliding frame 151 .

[0124] Reference Figure 2 In some embodiments, the second adjustment mechanism 17 includes a rotating member 171, which is rotatably mounted on the sliding base 15. It is understood that multiple rotating members 171 are rotatably connected to the sliding frame 151 via the same rotating shaft, and the corresponding rotating shafts are fixedly connected to the sliding frame 151. In other embodiments, each rotating member 171 may be rotatably connected to the sliding frame 151 via a separate rotating shaft.

[0125] Reference Figure 2 and Figure 3 The rotating member 171 is provided with a driving portion 1711 , and in the opposite direction of the rotation direction R of the rotating member 171 , the distance between the driving portion 1711 and the rotating axis of the rotating member 171 along the radial direction of the rotating axis of the rotating member 171 gradually increases.

[0126] In some embodiments, the drive rod 13 is provided with a mating portion 132, and the drive portion 1711 abuts against the mating portion 132 to drive the corresponding drive rod 13. It is understood that the mating portion 132 is located at one end of the drive rod 13 along the second direction Y and away from the drive surface 131. In some embodiments, the second adjustment mechanism 17 further includes an elastic component 172, which is disposed on the sliding seat 15 and connected to the corresponding drive rod 13 to provide the corresponding drive rod 13 with an elastic force that causes the corresponding drive portion 1711 to abut against the mating portion 132. It is understood that the elastic component 172 is disposed on the sliding frame 151. The elastic component 172 provides an elastic force on the drive rod 13 to keep the mating portion 132 and the drive portion 1711 in abutment, which can further ensure that the mating portion 132 and the drive portion 1711 remain in abutment.

[0127] Because the distance between the driving portion 1711 and the rotation axis of the rotating member 171 gradually increases in the direction opposite to the rotation direction R of the rotating member 171, when the rotating member 171 rotates in the forward direction, the distance between the engaging portion 132 and the rotation axis of the rotating member 171 gradually increases, thereby causing the driving rod 13 to move away from the rotating member 171 in the forward direction of the second direction Y. When the rotating member 171 rotates in the reverse direction, the distance between the engaging portion 132 and the rotation axis of the driving rod 13 decreases, causing the driving rod 13 to move closer to the rotating member 171 in the reverse direction of the second direction Y.

[0128] In other embodiments, the elastic component 172 can be omitted, and under the action of the reset member 14, the abutment surface 121 of the punch 12 and the driving surface 131 remain in abutment, and there is an interaction force between the abutment surface 121 and the driving surface 131, so that the matching portion 132 of the driving rod 13 and the driving portion 1711 can always remain in abutment.

[0129] In some embodiments, the rotating member 171 is an eccentric ratchet, which includes a plurality of continuously arranged tooth grooves 1712. It is understood that the plurality of continuously arranged tooth grooves 1712 of the eccentric ratchet form a driving portion 1711, and that the radial distance between each tooth groove 1712 and the rotation axis of the eccentric ratchet gradually increases in the direction opposite to the rotation direction R of the eccentric ratchet. In other embodiments, the rotating member 171 may be a cam, and the peripheral wall of the cam forms the driving portion 1711. It is understood that the driving portion 1711 is an arcuate surface, and the mating portion 132 is configured to abut the peripheral wall of the cam.

[0130] In some embodiments, the mating portion 132 is provided with a protruding tooth 1321, which is configured to abut against the inner wall of at least one tooth groove 1712. The protruding tooth 1321 is inserted into the tooth groove 1712 to limit the rotation of the eccentric ratchet to a certain extent, thereby improving the stability of the eccentric ratchet in maintaining its fixed position, thereby improving the stability of maintaining the position of the adjusted drive rod 13.

[0131] In some embodiments, the end of the protruding tooth 1321 is inclined relative to the second direction Y, and / or the opening of the tooth groove 1712 is inclined relative to the second direction Y. Specifically, the sidewalls of the protruding tooth 1321 on both sides along the rotational direction R of the eccentric ratchet are inclined relative to the second direction Y, and the inner walls of the tooth groove 1712 on both sides along the rotational direction R of the rotating member 171, into which the protruding tooth 1321 is inserted, are inclined relative to the second direction Y. Thus, during forward and reverse rotation of the eccentric ratchet, the inner walls of the tooth groove 1712 exert a driving force on the protruding tooth 1321, causing the protruding tooth 1321 to move toward the outside of the corresponding tooth groove 1712. In some embodiments, the sidewalls on each side of the protruding tooth 1321 are parallel to the inner walls of the corresponding tooth groove 1712. It can be understood that the side wall located on the front side of the protruding tooth 1321 along the positive direction of rotation R of the eccentric ratchet extends along the positive direction of the second direction Y and tilts in the reverse direction of the first direction X, and the side wall located on the rear side of the protruding tooth 1321 along the positive direction of rotation R of the eccentric ratchet extends along the positive direction of the second direction Y and tilts in the positive direction of the first direction X, so that the protruding tooth 1321 is conical.

[0132] When the eccentric ratchet rotates in the forward direction, the inner wall of the tooth groove 1712 along the positive direction of rotation R of the rotating member 171 in which the convex tooth 1321 is inserted pushes the convex tooth 1321, so that the convex tooth 1321 drives the driving rod 13 to move in the positive direction of the second direction Y, so that the convex tooth 1321 disengages from the current tooth groove 1712; when the eccentric ratchet rotates in the reverse direction, the inner wall of the tooth groove 1712 along the positive direction of rotation R of the rotating member 171 in which the convex tooth 1321 is inserted pushes the convex tooth 1321, so that the convex tooth 1321 drives the driving rod 13 to move in the positive direction of the second direction Y, so that the convex tooth 1321 disengages from the current tooth groove 1712. During the rotation of the eccentric ratchet, when the protruding tooth 1321 is aligned with any tooth groove 1712, under the joint action of the elastic component 172 and the reset member 14, the driving rod 13 moves in the opposite direction of the second direction Y, so that the protruding tooth 1321 is inserted into the corresponding tooth groove 1712.

[0133] In other embodiments, the side walls of the protruding tooth 1321 may be inclined relative to the second direction Y, and the inner wall of the tooth groove 1712 inserted in the protruding tooth 1321 may be parallel to the second direction Y. In other embodiments, the inner wall of the tooth groove 1712 in which the protruding tooth 1321 is inserted may be inclined relative to the second direction Y, and the side walls of the protruding tooth 1321 may be parallel to the second direction Y. It is sufficient as long as the inner wall of the tooth groove 1712 exerts a force on the protruding tooth 1321 to move the protruding tooth 1321 toward the outside of the corresponding tooth groove 1712 when the eccentric ratchet rotates.

[0134] When the eccentric ratchet is released, the rotating member 171 can automatically remain stationary due to the friction between the protruding teeth 1321 and the inner wall of the tooth groove 1712 and the friction between the eccentric ratchet and its own rotating shaft, so that the driving rod 13 remains fixed.

[0135] In other embodiments, the engaging portion 132 can be substantially aligned with the rotation axis of the rotating member 171 along the second direction Y, so that after the rotating member 171 is released, the torque exerted by the driving rod 13 on the rotating member 171 through the engaging portion 132 is zero, thereby keeping the rotating member 171 stationary. In other embodiments, a fixing member can be provided to fix the rotating member 171, so that the rotating member 171 can remain stationary after the rotating member 171 is released.

[0136] Reference Figure 3 and Figure 4 In some embodiments, the elastic component 172 includes an abutment column 1721 , an abutment rod 1722 , a reset elastic member 1723 and a swing arm 1724 .

[0137] In some embodiments, the swing arm 1724 is rotatably mounted on the sliding base 15. The swing arm 1724 has a first end 17241 and a second end 17242, with the first end 17241 and the second end 17242 respectively located on either side of the rotation axis of the swing arm 1724. The sliding base 15 also includes a mounting bracket 153, which is fixedly connected to the sliding bracket 151. It is understood that the swing arm 1724 is located forward of the drive rod 13 in the positive direction of the first direction X. The swing arm 1724 is rotatably connected to the mounting bracket 153 via the rotation axis, and in the positive direction of the first direction X, the first end 17241 of the swing arm 1724 is located forward of the second end 17242. In other embodiments, the swing arm 1724 may be located on one side of the drive rod 13 in the third direction Z.

[0138] In some embodiments, the mating portion 132 protrudes from the main body of the driving rod 13 in the positive direction of the first direction X, and the second end 17242 of the swing arm 1724 abuts against a side of the mating portion 132 in the second direction Y that faces away from the driving portion 1711. In other embodiments, the driving rod 13 may include a groove, allowing the second end 17242 of the swing arm 1724 to be inserted into the groove and configured to abut against the inner wall of the groove in the second direction Y that is closer to the driving portion 1711. In other embodiments, a protrusion may be provided on the driving rod 13, allowing the second end 17242 to abut against the protrusion, thereby enabling the second end 17242 to generate a force on the driving rod 13 in the opposite direction of the second direction Y.

[0139] In some embodiments, the abutment post 1721 is slidably disposed on the sliding seat 15 along the second direction Y. An abutment rod 1722 is protruding from an end wall of one end of the abutment post 1721 along the second direction Y. The end of the abutment rod 1722 distal from the abutment post 1721 is configured to connect to the drive rod 13. It will be appreciated that the cross-sectional area of ​​the abutment rod 1722 perpendicular to the second direction Y is smaller than the cross-sectional area of ​​the abutment post 1721 perpendicular to the second direction Y. In some embodiments, the abutment rod 1722 and the abutment post 1721 are integrally formed.

[0140] In some embodiments, the sliding seat 15 is provided with a sliding hole 1531, the abutting column 1721 slides and cooperates with the sliding hole 1531 along the second direction Y, the sliding seat 15 is provided with a supporting member 1532, the reset elastic member 1723 is provided in the sliding hole 1531, and the two ends of the reset elastic member 1723 respectively abut against the abutting column 1721 and the supporting member 1532.

[0141] It is understood that the mounting bracket 153 defines a sliding hole 1531 along the second direction Y. The sliding hole 1531 and the engaging portion 132 are both located on the same side of the swing arm 1724 along the second direction Y. The sliding hole 1531 extends through the side wall of the mounting bracket 153 at one end thereof, away from the swing arm 1724, along the second direction Y. A clearance hole 1533 is defined through the bottom wall of the other end of the sliding hole 1531 along the second direction Y. The abutment post 1721 is inserted into the sliding hole 1531 and slidably engages with the sliding hole 1531 along the second direction Y. The abutment rod 1722 is inserted into the clearance hole 1533 and abuts against the first end 17241 of the swing arm 1724. Reset elastic member 1723 is disposed within sliding hole 1531 and located on the side of abutting post 1721 facing away from abutting rod 1722. Abutting member 1532 is plate-shaped and blocks the opening of sliding hole 1531. Abutting member 1532 is fixedly connected to mounting bracket 153 via screws, so that the ends of reset elastic member 1723 respectively abut against abutting member 1532 and abutting post 1721. In some embodiments, the abutting posts 1721 of multiple elastic assemblies 172 are staggered so that each abutting rod 1722 can abut against the first end 17241 of a corresponding swing arm 1724 without contacting another adjacent swing arm 1724.

[0142] By causing the reset elastic member 1723 to undergo elastic compression deformation, the abutment rod 1722 has an elastic effect on the first end 17241, so that the second end 17242 has a reverse force on the matching portion 132 along the second direction Y, so that the matching portion 132 can maintain abutment with the driving portion 1711.

[0143] In other embodiments, the sliding hole 1531 may be omitted, and the abutting post 1721 may be slidably connected to the sliding seat 15 via a sliding rail, so that the reset elastic member 1723 can provide an elastic force to the second end 17242 via the abutting post 1721 and the abutting rod 1722. In other embodiments, the two ends of the reset elastic member 1723 may be fixedly connected to the sliding seat 15 and the abutting post 1721, respectively, and the abutting rod 1722 may be rotatably connected to the first end 17241. The reset elastic member 1723, the abutting post 1721, and the abutting rod 1722 may be disposed on a side of the swing arm 1724 that is away from the mating portion 132 along the second direction Y. By causing the reset elastic member 1723 to be stretched and deformed, the first end 17241 is subjected to an elastic force in the positive direction of the second direction Y, thereby causing the second end 17242 to be subjected to a force in the negative direction of the second direction Y.

[0144] In other embodiments, the swing arm 1724 may be omitted, and the abutting rod 1722 may abut against the side of the matching portion 132 along the second direction Y and away from the driving portion 1711, and the reset elastic member 1723 may abut against the sliding seat 15. When the reset elastic member 1723 is compressed and deformed, the reset elastic member 1723 exerts an elastic force on the matching portion 132 in the opposite direction of the second direction Y via the abutting column 1721 and the abutting rod 1722, thereby maintaining the matching portion 132 in abutment with the driving portion 1711. In other embodiments, the abutting column 1721 and the abutting rod 1722 may be omitted, and the two ends of the reset elastic member 1723 may abut against the matching portion 132 and the sliding seat 15, respectively, so that the reset elastic member 1723 provides a force in the opposite direction of the second direction Y to the matching portion 132.

[0145] In some embodiments, the position of the punch 12 is adjusted as follows:

[0146] First, the position of the sliding base 15 is adjusted by the first adjustment mechanism 16, so that the sliding base 15 drives the driving rod 13 to move along the second direction Y through the second adjustment mechanism 17, thereby preliminarily adjusting the positions of the plurality of punches 12. Then, the position of each driving rod 13 is further adjusted by each second adjustment mechanism 17 in turn, thereby further accurately adjusting the position of each punch 12. As described above, the positions of the plurality of punches 12 can be adjusted synchronously by the first adjustment mechanism 16, which can shorten the time required to adjust the positions of the plurality of punches 12, thereby improving the efficiency of adjusting the positions of the punches 12.

[0148] In some embodiments, the upper die 200 includes a die base 21, a pad 22, a template 23, and a stripper plate 24. The die base 21, the pad 22, the template 23, and the stripper plate 24 are stacked in sequence and connected to each other. The mounting plate 111 of the mounting seat 11 of the punch structure 100 is integrally formed with the die base 21, the connecting plate 112 of the mounting seat 11 is integrally formed with the pad 22, and the fixing plate 113 of the mounting seat 11 is integrally formed with the template 23. The first direction X is parallel to the direction of movement of the upper die 200 toward the lower die 300. The stripper plate 24 is provided with an avoidance hole 241 along the first direction X. The punch 12 is inserted into the avoidance hole 241 and protrudes from the surface of the stripper plate. In other embodiments, the mounting seat 11 of the punch structure 100 can also be fixedly connected to the die base 21 by bolts.

[0149] It should be noted that Figure 5 The dashed lines in the figure are used to separate the mounting plate 111 and the die base 21, the connecting plate 112 and the backing plate 22, and the fixing plate 113 and the template 23. However, the dividing lines between the mounting plate 111 and the die base 21, between the connecting plate 112 and the backing plate 22, and between the fixing plate 113 and the template 23 are not limited to the positions of the dashed lines in the figure. As long as the mounting plate 111 of the mounting base 11 is connected to the die base 21 and the punch 12 can abut against the corresponding part of the product to be processed, any boundary line can be used.

[0150] In other embodiments, the punch structure 100 can also be connected to the lower mold 300 as needed. The corresponding installation method can refer to the specific description of the connection between the punch structure 100 and the upper mold 200, as long as the punch 12 can abut against the corresponding part of the product to be processed.
