[0027] The terms "first", "second", and the like are only used to distinguish different objects, and cannot be understood as indicating or implying relative importance or implying the number, specific order or primary and secondary relationship of the indicated technical features.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs. The terms used in the specification of the present application are only for the purpose of describing specific embodiments and are not intended to limit the present application.

[0029] Punching is a forming process that applies external force to sheet, strip, pipe and profile, etc. to produce plastic deformation or separation, thereby obtaining the desired shape and size of the workpiece (punched part). A general punch press moves the punch head towards the upper die to press the workpiece together with the upper die, and the punch head ejects the workpiece from the upper die.

[0030] Some workpieces have requirements for the collapse and burr generated when they are punched, so the upper die needs to move towards the punch head. This punching method will cause the workpiece to be embedded in the die.

[0031] The present embodiment is illustrated by a workpiece punched and formed.

[0032] The embodiment of the present application provides a stripping mechanism, which comprises a main body, a stripping piece and a linkage assembly. The main body is provided with a cavity penetrating through the main body, and the main body is configured to move under the driving of a processing device. One end of the stripping piece is provided with a stripping guide column. The stripping piece and the linkage assembly are arranged in the cavity, and the stripping piece and the linkage assembly are respectively in sliding connection with the main body. The linkage assembly is located on one side of the stripping piece, and the linkage assembly is configured to move under the action of the main body and synchronously drive the stripping piece to move relative to the main body. The stripping guide column moves in the cavity until the linkage assembly is separated from the stripping piece. The stripping piece is configured to move from the cavity to the outside of the cavity under the action of an external force, so that the stripping guide column ejects the workpiece.

[0033] When the main body synchronously drives the stripping piece and the linkage assembly to move, the linkage assembly also drives the stripping piece to move relative to the main body, and the stripping piece drives the stripping guide column to move from the outside of the cavity to the inside of the cavity and away from the workpiece. When the main body moves a specified distance, the linkage assembly is separated from the stripping piece, the stripping piece moves relative to the main body to the outside of the cavity, and the stripping guide column acts on the workpiece outside the cavity to achieve the effect of stripping the workpiece.

[0034] Some embodiments of the present application will be described below in conjunction with the accompanying drawings. In the case of no conflict, the following embodiments and features in the embodiments can be combined with each other.

[0035] Please refer to Figures 1 to 5 An embodiment of the present application provides a stamping device 100 which comprises a lower die 11, an upper die 13 and a stamping head 12. The upper die 13 is connected with a stripping mechanism 14, the lower die 11 is arranged on one side of the upper die 13, and the lower die 11 and the upper die 13 have a certain interval. The stamping head 12 is arranged on the lower die 11, the free end of the stamping head 12 is higher than the lower die 11, and the upper die 13 is provided with a stamping hole 1413 facing the stamping head 12. Before work, the upper die 13 has a certain distance from the stamping head 12. During work, the upper die 13 moves to the lower die 11 under the action of a driving mechanism (not shown) of the stamping device 100, the upper die 13 cooperates with the stamping head 12 to stamp the material 20, part of the material 20 is trapped in the stamping hole 1413 and forms a workpiece 21. The stripping mechanism 14 is arranged on the upper die 13, the workpiece 21 is pushed out of the upper die 13 from the stamping hole 1413 through the stripping mechanism 14, so that automatic stripping is realized.

[0036] The upper die 13 and the lower die 11 are arranged opposite to each other along the Z-axis direction, and the X-axis, the Y-axis and the Z-axis are perpendicular to each other.

[0037] In some embodiments, please refer to Figures 2 to 5 The stripping mechanism 14 comprises a main body 141, a stripping piece 142 and a linkage assembly 140, please refer to Figures 4 to 6The main body 141 is detachably connected with the upper die 13. The main body 141 is provided with a cavity 1414 penetrating along the Z-axis direction. The cavity 1414 is in communication with one end of the punching hole 1413. The stripper 142 and the linkage assembly 140 are arranged in the cavity 1414. The stripper 142 and the linkage assembly 140 are slidably connected with the main body 141. One end of the stripper 142 is provided with a stripper guide column 1421. Part of the stripper guide column 1421 can extend from the cavity 1414 to outside of the cavity 1414. The linkage assembly 140 is located at one side of the stripper 142 along the X-axis direction.

[0038] It can be understood that when the stripper mechanism 14 is applied to the punching device 100, part of the stripper guide column 1421 can extend from the cavity 1414 to the punching hole 1413.

[0039] When the upper die 13 drives the main body 141 to move downward until the upper die 13 cooperates with the punching head 12, the punching head 12 punches and breaks part of the material 20 to form a workpiece 21, and the workpiece 21 is located in the punching hole 1413. After the punching is completed, the upper die 13 drives the main body 141 and the workpiece 21 to move upward away from the lower die 11.

[0040] When the upper die 13 drives the main body 141 to move upward, the linkage assembly 140 moves under the action of the main body 141. The linkage assembly 140 synchronously drives the stripper 142 to move upward relative to the main body 141, and moves the free end of the stripper guide column 1421 from the punching hole 1413 to the cavity 1414. When the main body 141 moves upward by a certain distance, the linkage assembly 140 is separated from the stripper 142. The stripper 142 moves downward from the cavity 1414 to the punching hole 1413 relative to the main body 141 and the linkage assembly 140 under the action of gravity, until the stripper guide column 1421 pushes the workpiece 21 in the punching hole 1413 out of the punching hole 1413, thereby achieving the effect of automatically stripping the workpiece 21 in the punching hole 1413.

[0041] The main body 141 is moved by the upper die 13, and the linkage assembly 140 and the stripper 142 are synchronously moved, so that the upper die 13 drives the stripper mechanism 14 to perform stripping work in a linkage manner without adding additional power equipment, to realize automatic stripping.

[0042] It can be understood that when the stripper mechanism 14 is applied to other processing equipment, the main body 141 is fixedly connected with a moving component of the other processing equipment. The main body 141 is moved synchronously by the other processing equipment, so that the moving component of the other processing equipment drives the stripper mechanism 14 to perform stripping work in a linkage manner without adding additional power equipment.

[0043] In other embodiments, the stripping mechanism 14 is also applied to an automatic delay device. By moving a certain distance in the stripping mechanism 14, the linkage assembly 140 is separated from the stripping member 142, and the stripping member 142 performs the stripping work to realize the delay function of the automatic delay device.

[0044] In some embodiments, the automatic delay device is arranged in a processing equipment such as a stamping equipment that needs stripping, so as to delay the stripping of the material 20 on the processing equipment according to the processing requirements of the processing equipment.

[0045] In some embodiments, the automatic delay device further comprises a driver for driving the movement of the main body 141, so as to actively control the stripping mechanism 14 of the automatic delay device, thereby improving the flexibility and controllability of the automatic delay device in operation.

[0046] In some embodiments, please refer to Figures 2 to 5 , the stripping mechanism 14 further comprises a fixed rack 143 extending along the Z-axis direction, the fixed rack 143 is arranged on one side of the main body 141 along the X-axis direction, and the bottom end of the fixed rack 143 is fixedly connected with the lower die 11. The linkage assembly 140 comprises a movable rack 1401 and a gear 1402, the movable rack 1401 extends along the Z-axis direction, and the movable rack 1401 is slidably connected with the main body 141. In the X-axis direction, the stripping member 142, the movable rack 1401, the gear 1402 and the fixed rack 143 are arranged in sequence.

[0047] Please refer to Figure 4 and Figure 5 , the movable rack 1401 is provided with a protruding portion 1403 extending towards the stripping member 142, and the gear 1402 is rotatably connected with the main body 141 and engaged with the movable rack 1401. The stripping mechanism 14 further comprises a movable block 144 slidably connected with the stripping member 142 and telescopically arranged towards the fixed rack 143, and part of the movable block 144 is configured to be telescopically arranged outside the stripping member 142 along the X-axis direction.

[0048] When the upper die 13 drives the main body 141 to move upward relative to the punch head 12, the main body 141 synchronously drives the gear 1402, the moving rack 1401, the stripping part 142 and the movable block 144 to move relative to the fixed rack 143. The gear 1402 is engaged with the fixed rack 143 and rotates relative to the main body 141 under the action of the fixed rack 143. The gear 1402 drives the moving rack 1401 to move upward relative to the main body 141, so that the protruding part 1403 contacts the side of the movable block 144 facing downward and supports the movable block 144. The moving rack 1401 drives the movable block 144 to move upward relative to the main body 141 through the protruding part 1403 and synchronously drives the stripping part 142 to move, so as to realize the relative movement of the stripping part 142 relative to the main body 141 driven by the linkage assembly 140.

[0049] When the moving rack 1401 drives the movable block 144 and the stripping part 142 to move upward relative to the main body 141 by a certain distance, the movable block 144 retracts from the moving rack 1401 to the stripping part 142 and separates from the protruding part 1403. The stripping part 142 drives the movable block 144 to move downward relative to the main body 141 and the moving rack 1401 under the action of gravity.

[0050] In some embodiments, referring to Figure 4 , the movable block 144 is provided with a first inclined surface 1441 facing the extending end of the moving rack 1401. The first inclined surface 1441 extends from the top left to the bottom right. Figure 4 The stripping mechanism 14 further comprises a stop block 145 which is arranged in the cavity 1414 and fixedly connected with the main body 141. Along the X-axis direction, the stop block 145 is located between the movable block 144 and the moving rack 1401 and above the movable block 144. The side of the stop block 145 facing the movable block 144 is provided with a second inclined surface 1451 which extends from the top left to the bottom right. Figure 4

[0051] When the moving rack 1401 drives the movable block 144 to move upward relative to the main body 141 by a certain distance through the protruding part 1403, the first inclined surface 1441 of the movable block 144 contacts the second inclined surface 1451. The second inclined surface 1451 exerts a force on the movable block 144 and makes the movable block 144 retract along the X-axis direction to the stripping part 142 and away from the protruding part 1403, so as to realize the separation of the movable block 144 from the protruding part 1403.

[0052] ​In other embodiments, the stripping mechanism 14 further comprises a connecting member (not shown) located on the side of the movable block 144 away from the moving rack 1401, one end of the connecting member is connected with the main body 141, and the other end is connected with the movable block 144. During the upward movement of the stripping member 142 and the movable block 144 driven by the moving rack 1401, due to the fixed length of the connecting member, when the movable block 144 moves away from the other end of the connecting rope, the movable block 144 moves away from the moving rack 1401 along the X-axis direction under the restriction of the connecting member until the movable block 144 is separated from the protruding part 1403. The connecting member is in a rope structure, and the material thereof can also be an elastic material. For example, the connecting member is a rubber band.

[0053] In some embodiments, referring to Figures 3 to 5 , the stripping mechanism 14 further comprises a first elastic member 146 connected with the stripping member 142 and the movable block 144 respectively. When the movable block 144 moves away from the moving rack 1401, the movable block 144 compresses the first elastic member 146. After the movable block 144 is separated from the protruding part 1403, the first elastic member 146 elastically resets and pushes the movable block 144 to move close to the moving rack 1401 along the X-axis direction, so as to reset the movement of the movable block 144, thereby improving the automatic function of the stripping member 142.

[0054] In some embodiments, relative to the downward movement of the stripping member 142 under the action of gravity, the force storage element can be used to store force, and then the force storage element is connected to drive the stripping member 142 to move downward. Referring to Figure 4 and Figure 5 , the stripping mechanism 14 further comprises a second elastic member 147 located on the top of the stripping member 142, and the second elastic member 147 is connected with the main body 141 and the stripping member 142 respectively. When the stripping member 142 moves upward relative to the main body 141, the stripping member 142 compresses the second elastic member 147. When the movable block 144 is separated from the protruding part 1403, the second elastic member 147 applies a force to the stripping member 142 and pushes the stripping member 142 to move downward relative to the main body 141.

[0055] In some embodiments, the stripping member 142 and the stripping guide column 1421 are detachably connected, so as to replace different stripping guide columns 1421 corresponding to different punching holes 1413.

[0056] In the horizontal direction, the cross-sectional area of the punching hole 1413, the cross-sectional area of the stripper 142, and the cross-sectional area of the cavity 1414 increase in turn to avoid the stripper 142 entering the punching hole 1413 together with the stripper guide pillar 1421, so that the stripper 142 can be in contact with the upper die 13 to support the stripper 142 in the cavity 1414 by the upper die 13 and limit the downward movement distance of the stripper 142.

[0057] It can be understood that the side of the cavity 1414 facing the upper die 13 is provided with a limiting piece, which supports the stripper 142 and also limits the downward movement distance of the stripper 142 in the cavity 1414.

[0058] In some embodiments, referring to Figures 3 to 5 , the part of the fixed rack 143 close to the lower die 11 is toothless. When the upper die 13 drives the main body 141 to drive the gear 1402 to move downward by a certain distance, the gear 1402 is separated from the fixed rack 143, the fixed rack 143 cancels the force generated by the gear 1402 on the moving rack 1401, the moving rack 1401 drives the protruding part 1403 to move downward relative to the main body 141, the fixed rack 143, and the stripper 142 under the action of gravity, and makes the protruding part 1403 act on the first inclined surface 1441, the protruding part 1403 pushes the movable block 144 to compress the first elastic piece 146 in the X-axis direction, and makes the movable block 144 move away from the moving rack 1401, until the moving rack 1401 drives the protruding part 1403 to move below the movable block 144, so that the protruding part 1403 can support the movable block 144 to move upward again. It can be understood that the speed of the main body 141 at this time is less than the acceleration of gravity.

[0059] In some embodiments, instead of the moving rack 1401 descending by gravity, the moving rack 1401 can be driven to move downward by a force storage element after storing force. Referring to Figure 4 and Figure 5 , the stripper mechanism 14 further comprises a third elastic piece 148, the third elastic piece 148 is located at the top of the moving rack 1401, and the third elastic piece 148 is connected with the main body 141 and the moving rack 1401 respectively. When the moving rack 1401 moves upward relative to the main body 141, the moving rack 1401 compresses the third elastic piece 148. When the gear 1402 is separated from the fixed rack 143, the third elastic piece 148 exerts a force on the moving rack 1401, and makes the moving rack 1401 drive the protruding part 1403 to move downward relative to the main body 141, the fixed rack 143, and the stripper 142, and drive the protruding part 1403 to act on the first inclined surface 1441.

[0060] In some embodiments, when the mobile rack 1401 is lowered by a certain distance relative to the main body 141, the main body 141 limits the mobile rack 1401 to inhibit the mobile rack 1401 from continuing to move downward relative to the main body 141, which helps to reduce the risk of collision between the mobile rack 1401 and the lower die 11 or the upper die 13.

[0061] In some embodiments, referring to Figure 6 , the stamping device 100 further comprises a floating member 15 movably arranged on the lower die 11, the floating member 15 is provided with a through hole 151 along the Z axis, and a fourth elastic member 16 connected with the floating member 15 and the lower die 11 respectively. The part of the stamping head 12 close to the upper die 13 is located in the through hole 151, and the distance between the floating member 15 and the upper die 13 is less than the distance between the stamping head 12 and the upper die 13, that is, the top surface of the floating member 15 is higher than the top surface of the stamping head 12 in the vertical direction of gravity.

[0062] When the material 20 is conveyed between the lower die 11 and the upper die 13, the material 20 is located on the floating member 15, and the material 20 does not contact the stamping head 12.

[0063] When the upper die 13 drives the main body 141 to move downward and close to the main body 141, the upper die 13 acts on the material 20 towards the floating member 15, and moves the floating member 15 relative to the stamping head 12 through the material 20, the fourth elastic member 16 is compressed, the fourth elastic member 16 exerts an upward force on the floating member 15, and the floating member 15 and the upper die 13 jointly clamp the material 20, which helps to reduce the risk of displacement of the material 20, the upper die 13 continues to push the material 20 and the floating member 15 downward, until the material 20 contacts the stamping head 12, and then the upper die 13 cooperates with the stamping head 12 to stamp the material 20.

[0064] In some embodiments, the first elastic member 146, the second elastic member 147, the third elastic member 148 and the fourth elastic member 16 are compression springs or elastic members such as rubber with elasticity.

[0065] In some embodiments, when the upper die 13 drives the main body 141 to move downward, the stripping guide column 1421 extends downward in the stamping hole 1413 to the outside of the stamping hole 1413, and before the upper die 13 contacts the material 20, the stripping guide column 1421 contacts the material 20, and the material 20 supports the stripping member 142 to compress the first elastic member 146 through the stripping guide column 1421, the first elastic member 146 exerts a downward force on the stripping member 142, and the stripping member 142 presses the material 20 through the stripping guide column 1421, which helps to reduce the risk of displacement of the material 20.

[0066] In some embodiments, the stripper guide post 1421 and the floating member 15 can simultaneously elastically act on the material 20 before the upper die 13 cooperates with the punch head 12 to punch the material 20.

[0067] In addition, those skilled in the art should understand that the above-mentioned embodiments are only used to illustrate the present application, but not as a limitation to the present application, and as long as the above-mentioned embodiments are appropriately changed and changed within the essential scope of the present application, they fall within the scope of the present application.
