[0046] In view of this, the utility model proposes a stamping mechanism and a stamping device to reduce the phenomenon of clogging of the leakage hole.

[0047] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are intended only to explain the relevant utility model and are not intended to limit the utility model. The embodiments described herein are merely a portion of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort shall fall within the scope of protection of the present invention.

[0048] See also Figures 1 to 3 The embodiment of the present invention discloses a stamping mechanism, including a wedge push rod 1, a splint block 2, a conversion assembly 3 and a punching needle 25, wherein: the conversion assembly 3 is in transmission cooperation with one end of the wedge push rod 1 to output a lateral thrust to the wedge push rod 1; the wedge push rod 1 is slidably cooperated with the wedge-shaped surface of the splint block 2 and moves back and forth in the lateral direction; when the wedge push rod 1 moves a preset distance in the lateral direction under the action of the lateral thrust, it pushes the splint block 2 in the vertical direction to move the top material distance, thereby causing the punching needle 25 connected to the splint block 2 to move the top material distance.

[0049] The punching mechanism of the present invention is mounted on the punching equipment via fasteners. The conversion assembly 3 cooperates with the mold closing action of the punching equipment to cause the wedge push rod 1 to output a lateral thrust. The wedge push rod 1 moves laterally and pushes the clamping plate entry block 2 to move an additional distance in the vertical direction to push out the material, thereby causing the punching needle 25 connected to the clamping plate entry block 2 to move an additional distance in the vertical direction to push out the material, thereby ejecting the waste material at the leakage hole at the blade edge. It can be seen that the punching mechanism of the present invention can clean up the waste material at the leakage hole at the blade edge in a timely manner, thereby reducing the blockage of the leakage hole and extending the service life of the punch without affecting normal production and reducing the cost of mold repair.

[0050] In some examples, the splint block 2 includes a splint block body 21, a reset member 211, a first fastener 212, a stopper 24, a punch 25 and a punching block 22, wherein: one end of the splint block body 21 cooperates with the wedge push rod 1; the first fastener 212 positions the splint block body 21 in the vertical direction; the reset member 211 is located between the first fastener 212 and the splint block body 21 to provide a moving space for the splint block body 21 in the vertical direction; the stopper 24 is located in the middle of the splint block body 21; the punching block 22 is installed on the splint block body The other end of the body 21; one end of the punch 25 abuts against the stop block 24, and the other end extends out of the splint block body 21, and pushes out the waste material at the cutting edge during the vertical movement; the conversion assembly 3 is in transmission cooperation with one end of the wedge push rod 1 to output a lateral thrust to the wedge push rod 1; the wedge push rod 1 slides with the wedge surface of the splint block 2 and moves back and forth in the horizontal direction; when the wedge push rod 1 moves a preset distance in the horizontal direction under the action of the lateral thrust, it pushes the splint block 2 in the vertical direction to move the material pushing distance, thereby causing the punch 25 connected to the splint block 2 to move the material pushing distance.

[0051] The punching mechanism of the present invention is mounted on the punching equipment via fasteners. The conversion assembly 3 cooperates with the mold closing action of the punching equipment to cause the wedge push rod 1 to output a lateral thrust. The wedge push rod 1 moves laterally and pushes the clamping plate into the block body 21, the reset member 211, the stopper 24, and the punching needle 25 to move an additional ejection distance in the vertical direction. The punching needle 25 ejects the waste material at the leakage hole at the blade edge. It can be seen that the punching mechanism of the present invention can clean up the waste material at the leakage hole at the blade edge in a timely manner, thereby reducing the blockage of the leakage hole and extending the service life of the punching knife without affecting normal production and reducing the cost of mold repair.

[0052] It should be noted that, for the convenience of description, the present invention defines the vertical direction of movement of the splint block 2 as the Z-axis direction, the lateral direction of movement of the wedge push rod 1 as the X-axis direction, and the arrangement direction of the conversion component 3 as the Y-axis direction, wherein the Z-axis direction, the X-axis direction and the Y-axis direction are perpendicular to each other.

[0053] In some examples, the splint block body 21 is installed on the upper die 20 of the stamping equipment through a first fastener 212, and the punching plate block 22 is installed on the upper die 20 of the stamping equipment through a second fastener 221, and the splint block body 21 slides relative to the punching plate block 22 to drive the punching needle 25 installed on the splint block body 21 to make additional movements.

[0054] The above-mentioned first fastener 212 and second fastener 221 can both be understood as fasteners, and the fasteners are structures for realizing the connection between the above-mentioned stamping mechanism and the stamping equipment. In the embodiment of the present utility model, for the convenience of understanding, the fasteners for realizing the connection between different components of the stamping mechanism and the stamping equipment are defined as the first fastener 212 and the second fastener 221, as well as the third fastener 231, the fourth fastener 441 and the fifth fastener 442 mentioned below.

[0055] The splint block body 21 can move downward in the Z-axis direction under the push of the wedge push rod 1. In order to drive the splint block body 21 to be reset in time after the thrust of the wedge push rod 1 is withdrawn, in this example, it is reset by the reset member 211, and the reset member 211 pushes the entire splint block body 21 to move upward in the Z-axis direction.

[0056] Specifically, the main body 21 of the splint insert is provided with a guide hole for installing the reset member 211. The guide hole is open at the bottom. The reset member 211 is installed in the guide hole after being sleeved on the first fastener 212, and is then installed on the upper die 20 of the stamping equipment through the guide hole. In this example, the first fastener 212 not only realizes the connection between the main body 21 of the splint insert and the stamping equipment, but also positions the reset member 211 and realizes the installation of the reset member 211 and the main body 21 of the splint insert.

[0057] In some examples of the present invention, different fasteners are used for the installation of the clamping plate block body 21 and the installation shell of the reset member 211.

[0058] The clamping plate entry block body 21 can slide relative to the punching plate entry block 22 to guide the punching plate entry block 22. Specifically, the clamping plate entry block body 21 can also include a guide groove 222. The portion where the clamping plate entry block body 21 cooperates with the guide groove 222 is consistent with the shape of the guide groove 222. The punching needle 25 passes through the punching plate entry block 22 to perform the punching action.

[0059] Furthermore, the punch pin 25 is positioned on the splint block body 21 through a baffle, and the number of the punch pins 25 can be adjusted according to the requirements of the workpiece 10. In order to achieve the positioning of multiple punch pins 25, in the example of the present invention, the splint block 2 can also include a positioning pin 26, which separates adjacent punch pins 25.

[0060] In the above-mentioned stamping mechanism, the stamping mechanism also includes a lower cutting edge 23 corresponding to the punching needle 25, and the lower cutting edge 23 is arranged on the lower die 30. Specifically, the lower cutting edge 23 is installed on the lower die 30 through a third fastener 231 to cooperate with the punching needle 25 of the splint block 2 to punch the material.

[0061] See also Figure 4In some examples, the first wedge surface 11 is where the wedge push rod 1 engages with the plate insert 2, and the second wedge surface 213 is where the plate insert 2 engages with the wedge push rod 1. As the wedge push rod 1 moves laterally toward the plate insert 2, the first wedge surface 11 contacts the second wedge surface 213, converting the lateral movement of the wedge push rod 1 into vertical downward movement of the plate insert body 21, thereby enabling the plate insert body 21 to move downward according to the material-lifting distance.

[0062] See also Figure 5 The portion where the wedge push rod 1 and the conversion assembly 3 meet is provided with a raised portion 12, which is in driving engagement with the conversion assembly 3. Furthermore, to reduce friction between the raised portion 12 and the wedge push rod 1, the raised portion 12 has a rolling element 13. When the rolling element 13 contacts the conversion assembly 3, the rolling element 13 rolls, thereby converting into a rolling pair.

[0063] The conversion assembly 3 may include a cam 31, and the wedge push rod 1 cooperates with the cam 31. Under the action of the reset member 211 of the clamping plate insert 2, the wedge push rod 1 always fits with the cam 31 of the conversion assembly 3. The cam 31 is provided with a protrusion. When the protrusion contacts the wedge push rod 1, the cam 31 can push the wedge push rod 1 to move closer to the clamping plate insert 2.

[0064] The conversion assembly 3 may also include a rotating shaft 32, on which a cam 31 is mounted and in transmission engagement. The cam 31 lifts the wedge push rod 1, providing lateral thrust to the wedge push rod 1. In some embodiments of the present invention, the rotating shaft 32 is a splined shaft. The cam 31 includes an internal gear 42 that mates with the splined shaft.

[0065] It should be noted that the above description only describes the case where one cam 31 is mounted on one shaft 32 and one cam 31 cooperates with one wedge push rod 1. In some other examples of the present invention, multiple cams 31 may be mounted on one shaft 32, each cam 31 corresponding to one wedge push rod 1, and one wedge push rod 1 corresponding to one clamping plate insert 2.

[0066] The conversion assembly 3 may further include a bracket 33, on which the rotating shaft 32 is rotatably disposed, so that the conversion assembly 3 can be mounted on the upper die 20 of the stamping device. In order to reduce the friction between the bracket 33 and the rotating shaft 32, in some examples, the conversion assembly 3 may further include a bearing disposed between the bracket 33 and the rotating shaft 32. The bearing can reduce the friction between the bracket 33 and the rotating shaft 32 on the one hand, and improve the smoothness of the rotating shaft 32 during movement on the other hand.

[0067] Furthermore, in order to ensure the stable rotation of the rotating shaft 32 on the bracket 33, in some examples of the present invention, the conversion assembly 3 may also include a nut 34 arranged on the rotating shaft 32, and the nut 34 is threadedly engaged with the rotating shaft 32 to limit the axial movement of the rotating shaft 32 relative to the bracket 33, thereby improving the stability of the movement process of the rotating shaft 32.

[0068] The above punching mechanism conversion assembly 3 can convert its own rotational motion into the lateral movement of the wedge push rod 1. To this end, the punching mechanism in the present utility model also includes a drive assembly 4, see Figures 6 to 11 The drive assembly 4 is in transmission connection with the conversion assembly 3 to provide power support for the conversion assembly 3. The drive assembly 4 can be manually driven, electrically driven, hydraulically driven, etc. The drive assembly 4 of the example of the present utility model can also convert the motion of the stamping equipment itself into the rotation of the conversion assembly 3.

[0069] The driving assembly 4 includes a gear 42 and a rack 41. The gear 42 is in transmission connection with the conversion assembly 3. When the rack 41 is engaged with the gear 42, the gear 42 can be driven to rotate.

[0070] In some examples of the present invention, the rack 41 of the driving assembly 4 is arranged on the lower die 30 of the stamping equipment, and the gear 42 of the driving assembly 4 is arranged on the conversion assembly 3. When the rack 41 moves following the lower die 30, the rack 41 is engaged with the gear 42 to drive the gear 42 to rotate. The rotation of the gear 42 drives the rotating shaft 32 of the conversion assembly 3 to rotate around its own axis. The rotating shaft 32 drives the cam 31 to rotate, thereby pushing the wedge push rod 1 to move in the direction close to the splint entry block 2, thereby further pushing the splint entry block body 21 of the splint entry block 2 to move in the vertical direction according to the ejection distance.

[0071] The drive assembly 4 may further include a fixed base 44, with the rack 41 extending in the vertical direction. The rack 41 is mounted on the fixed base 44. The fixed base 44 is mounted on the lower die 30 of the stamping equipment via a fourth fastener 441. Furthermore, to reduce the difficulty of installing the fixed base 44 and the lower die 30, in this example of the utility model, the fixed base 44 may also include a positioning pin 443. The positioning pin 443 is used to achieve preliminary positioning of the fixed base 44 and the lower die 30, and the fourth fastener 441 is used to achieve installation of the fixed base 44 and the lower die 30.

[0072] The rack 41 and the fixing seat 44 are an integrated structure or a split structure. The split structure is a detachable connection or a non-detachable connection. Specifically, the rack 41 is fixed to the fixing seat 44 by a fifth fastener 442 .

[0073] To further enhance the stability of the transmission between gear 42 and conversion assembly 3, in this embodiment of the present invention, a one-way transmission assembly 43 is provided between gear 42 and conversion assembly 3. This one-way transmission assembly 43 transmits the rotational force of gear 42 in the target direction to conversion assembly 3. When rack 41 moves toward gear 42 and engages with it, gear 42, driven by one-way transmission assembly 43, drives shaft 32 to rotate in the first direction. When rack 41 and gear 42 move from the engaged state toward gear 42, the one-way transmission assembly 43 between gear 42 and shaft 32 causes gear 42 to disengage from shaft 32. Consequently, only gear 42 rotates relative to shaft 32 in the second direction, while shaft 32 does not rotate.

[0074] It can be seen that the function of the one-way transmission component 43 is to realize transmission between the gear 42 and the rotating shaft 32 in a preset direction, while the gear 42 and the rotating shaft 32 do not transmit in the direction opposite to the preset direction.

[0075] See also Figure 11 The one-way transmission assembly 43 shown in the figure includes a fixed sleeve 431, a claw 432, an elastic member 433 and a connecting member (not shown), wherein the fixed sleeve 431 is fixedly connected to the conversion assembly 3 through the connecting member, one end of the claw 432 is rotatably set on the fixed sleeve 431, and the other end of the claw 432 is matched with the ratchet 421 inside the gear 42; the elastic member 433 is located between the claw 432 and the fixed sleeve 431, so that when the gear 42 rotates in the target direction, the claw 432 of the gear 42 is matched with the ratchet transmission, and when the gear 42 rotates in the opposite direction of the target direction, the claw 432 of the gear 42 is disengaged from the ratchet transmission.

[0076] In order to facilitate the understanding of the above scheme, Figure 11 The target direction is clockwise, and the opposite direction of the target direction is counterclockwise.

[0077] When the rack 41 moves upward relative to the gear 42, the rack 41 drives the gear 42 to rotate clockwise. At this time, the claw 432 and the fixed sleeve 431 are in transmission cooperation, and the fixed sleeve 431 is fixedly connected to the rotating shaft 32, so that the rotating shaft 32 rotates clockwise, thereby converting the linear motion of the rack 41 into the rotational motion of the rotating shaft 32.

[0078] When the rack 41 moves downward relative to the gear 42, the rack 41 drives the gear 42 to rotate counterclockwise. At this time, the transmission between the claw 432 and the fixing sleeve 431 is disconnected, and the rotating shaft 32 will not rotate with the gear 42, thereby achieving the transmission disconnection between the rack 41 and the rotating shaft 32.

[0079] See also Figure 12 and Figure 13 , Figure 12 The stamping equipment in the open mode is shown in Figure 13The stamping device in the closed state is shown in FIG. The stamping device includes an upper die 20, a lower die 30 and a stamping mechanism as described above, wherein the stamping mechanism wedge push rod 1, clamping plate insert 2 and conversion assembly 3 are located in the upper die 20.

[0080] When the stamping equipment is in the open mode, the upper die 20 and the lower die 30 are separated, and the wedge push rod 1, the clamping plate block body 21, the punching plate block 22 and the conversion assembly 3 located in the upper die 20 are also separated from the lower die 30.

[0081] When the stamping equipment is in the closed mode, the upper die 20 and the lower die 30 are closed, and the wedge push rod 1, the clamping plate block body 21, the punching plate block 22 and the conversion assembly 3 located in the upper die 20 are also closed with the lower die 30.

[0082] In the process of moving from the open mold state to the closed mold state, the punch needle 25 of the punching device of the present invention first contacts the workpiece 10 on the lower mold 30 to punch the material. The rotational motion of the conversion assembly 3 is converted into the lateral movement of the wedge push rod 1, which is converted into the vertical movement of the clamping plate insert body 21, and further converted into additional movement of the punch needle 25 to flush away the waste material on the workpiece 10.

[0083] Furthermore, under the premise that the stamping mechanism includes the driving assembly 4 , the rack 41 of the driving assembly 4 is arranged on the lower die 30 , and the gear 42 of the driving assembly 4 is arranged on the conversion assembly 3 .

[0084] When the stamping equipment moves from the open mode to the closed mode, the punch 25 first contacts the workpiece 10 on the lower die 30 to punch the material. In the above process, the rack 41 and the gear 42 cooperate to drive the conversion assembly 3 to rotate. The rotational motion of the conversion assembly 3 is converted into the lateral movement of the wedge push rod 1. The lateral movement of the wedge push rod 1 is converted into the vertical movement of the clamping plate insert body 21, which is further converted into additional movement of the punch 25 to flush away the waste material on the workpiece 10.

[0085] The stamping equipment is not prone to small hole blockage; since blockage is not prone to occur, the continuity of production is guaranteed and the stamping production efficiency is greatly improved.
