[0002] At present, in metal stamping processing, the forming of shell-shaped parts often requires the formation of inclined bosses and inclined holes at a certain angle to the horizontal or vertical direction on the surface of the parts. When it is necessary to form an inclined boss and an inclined hole at a preset position on the same shell-shaped part at the same time, the first stamping die is usually used to stamp out the inclined boss at the preset position of the shell part, and then the second stamping die is used to stamp out the inclined boss at the preset position of the shell to stamp out the inclined hole on the inclined boss. Therefore, the shell part needs to be positioned and stamped twice, which not only increases the production process, but also easily leads to positioning errors, making it difficult to accurately control the size of the shell part after forming, and reducing the stamping accuracy.

[0048] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0049] See also Figure 1 and Figure 2 The embodiment of the present application provides a stamping die 100, which includes a lower die assembly 10 carrying a workpiece 200, an upper die assembly 20 movably disposed on the lower die assembly 10, and a movable assembly 30 movably connected to the upper die assembly 20. The stamping die 100 can simultaneously form an inclined boss 201 and an inclined hole 202 at a preset position of the workpiece 200, thereby improving stamping accuracy. The workpiece 200 may be a computer back panel.

[0050] Please refer to Figure 3 , Figure 4 and Figure 5 The lower die assembly 10 includes a carrier 11 that carries a workpiece 200, a blade 12 that is movably disposed in the carrier 11, and a third elastic member 13 that elastically abuts against the carrier 11 and the blade 12. The carrier 11 carries the workpiece 200 and is arranged opposite to the upper die assembly 20, and the upper die assembly 20 punches the workpiece 200 carried by the carrier 11 to form an inclined boss 201 on the upper surface of the workpiece 200. The blade 12 is arranged obliquely to the mold closing direction of the upper die assembly 20 and the lower die assembly 10 and is movably disposed in the carrier 11. The blade 12 cooperates with the movable assembly 30 to punch the inclined boss 201 and forms an inclined hole 202 on the inclined boss 201. The elastic force direction of the third elastic member 13 is parallel to the mold closing direction, one end of the third elastic member 13 is connected to the blade 12, and the other end of the third elastic member 13 abuts against the carrier 11. In this embodiment, the third elastic member 13 can be a spring.

[0051] In this way, by setting the above-mentioned lower mold assembly 10, when the upper mold assembly 20 stamps and forms the inclined boss 201, the upper mold assembly 20 presses the blade piece 12 extending out of the carrier 11 through the workpiece 200 placed on the carrier 11, so that the blade piece 12 compresses the third elastic piece 13 into the carrier 11, so that the compressed third elastic piece 13 provides elastic force to drive the blade piece 12 to reset and drive the stamped workpiece 200 to separate from the carrier 11 after the stamping operation is completed, which is beneficial for the stamping die 100 to repeat the stamping operation.

[0052] See also Figure 4The carrier 11 is provided with a limiting groove 111 and an accommodating groove 112 which are connected to each other in sequence along the direction from the pressing member 21 to the carrier 11 , and the accommodating groove 112 receives the third elastic member 13 . The blade member 12 includes a blade body 121 movably inserted into the carrier 11 and a limiting body 122 connected to the blade body 121. The blade body 121 is roughly cylindrical. The blade body 121 is movably inserted into the carrier 11 and extends into the limiting groove 111. The blade body 121 is provided with a through groove 1211. The through groove 1211 penetrates both sides of the blade body 121 along the axial direction of the blade body 121. The through groove 1211 cooperates with the movable component 30 to form an inclined hole 202. One end of the limiting body 122 is located in the limiting groove 111 and is connected to the blade body 121. The other end of the limiting body 122 extends into the accommodating groove 112 and abuts against the third elastic member 13. The limiting body 122 abuts against the bottom of the limiting groove 111 adjacent to the clamping member 21 to limit the blade body 121.

[0053] In this way, the limiting body 122 is driven by the third elastic member 13 to abut against the bottom of the limiting groove 111 adjacent to the upper mold assembly 20, thereby limiting the movement distance of the blade body 121, preventing the blade body 121 from extending too long from the carrier 11 and causing the blade body 121 to detach from the carrier 11, thereby facilitating repeated stamping operations of the blade body 121.

[0054] Please continue reading Figure 4 The number of the third elastic members 13 is multiple, that is, two, three, four, etc. In this embodiment, the number of the third elastic members 13 is specifically two, and the two third elastic members 13 are spaced apart in the vertical direction of the mold closing direction of the upper mold assembly 20 and the lower mold assembly 10, that is, Figure 4 The X-axis direction shown. The limiting body 122 includes a limiting portion 1221 and two connecting portions 1222 respectively connected to the limiting portion 1221. The limiting portion 1221 is roughly block-shaped. The limiting portion 1221 is arranged in the limiting groove 111 and connected to the blade body 121. Each connecting portion 1222 is roughly rod-shaped. The two connecting portions 1222 are arranged at intervals on the side of the limiting portion 1221 away from the blade body 121 and respectively abut the corresponding third elastic member 13. It can be understood that the third elastic member 13 and the limiting portion 1221 can be adaptively adjusted according to the use requirements, and always maintain a one-to-one corresponding setting. For example, when the number of the third elastic members 13 is three, the number of the limiting portions 1221 is also three.

[0055] In this way, by setting the limit body 122, the two connecting parts 1222 can be simultaneously abutted against the corresponding third elastic member 13, thereby increasing the contact area between the limit body 122 and the third elastic member 13, and then the third elastic member 13 can stably drive the limit body 122 to extend out of the supporting member 11 after the stamping operation is completed, so as to push the workpiece 200 away from the supporting member 11.

[0056] The carrier 11 includes a carrier 113 disposed opposite to the upper mold assembly 20, and a contoured body 114 embedded in the carrier 113. The carrier 113 is generally block-shaped, and the upper mold assembly 20 is movably disposed on the carrier 113. The limiting groove 111 is disposed on the side of the carrier 113 facing the pressing member 21. The contoured body 114 is generally block-shaped, and is embedded in the carrier 113 and adapted to the workpiece 200. The limiting groove 111 is disposed on the side of the contoured body 114 away from the pressing member 21. The blade body 121 is movably disposed through the contoured body 114, and the contoured body 114 positions the workpiece 200 and cooperates with the carrier 113 to carry the workpiece 200.

[0057] In this way, by setting the above-mentioned contoured body 114, the contoured body 114 can be adapted to the workpiece 200 to be punched, so as to position the workpiece 200 and cooperate with the carrier 113 to support the workpiece 200, so that the workpiece 200 maintains the preset orientation and placement position under the support of the contoured body 114, which is beneficial to ensure the bearing stability of the carrier 11.

[0058] Please also read Figure 4 , Figure 5 and Figure 6 The upper die assembly 20 includes a clamping member 21 movably disposed on the carrier 11, a stamping member 22 movably penetrated through the clamping member 21, and a first elastic member 23 elastically abutting against the clamping member 21 and the stamping member 22. The clamping member 21 is arranged opposite to the carrier 11 and is provided with an inclined guide hole 211. The inclined guide hole 211 is arranged obliquely to the mold closing direction of the upper die assembly 20 and the lower die assembly 10. The clamping member 21 presses the workpiece 200 to the carrier 11. The stamping member 22 is movably penetrated through the inclined guide hole 211 and extends out from the inclined guide hole 211 to stamp the workpiece 200 and form an inclined boss 201 on the surface of the workpiece 200. There are two first elastic members 23, and the two first elastic members 23 are spaced apart from each other on the clamping member 21 in a direction perpendicular to the mold closing direction of the upper die assembly 20 and the lower die assembly 10, that is, Figure 6 In the X-axis direction shown, the elastic force direction of the first elastic member 23 is parallel to the closing direction of the upper mold assembly 20 and the lower mold assembly 10, and the two ends of the first elastic member 23 elastically abut the pressing member 21 and the stamping member 22. In this embodiment, the first elastic member 23 can be a spring.

[0059] In this way, the workpiece 200 is pressed against the carrier 11 by the pressing member 21, so that the workpiece 200 can maintain the preset orientation and placement position, which facilitates the stamping member 22 to accurately stamp the workpiece 200 to form the inclined boss 201 on the surface of the workpiece 200, thereby improving the stamping accuracy. In addition, when the stamping member 22 moves close to the workpiece 200 under the guidance of the inclined guide hole 211, the first elastic member 23 is compressed by the stamping member 22 to the pressing member 21. When the stamping operation is completed, the compressed first elastic member 23 provides elastic force to drive the stamping member 22 to reset, so that the stamping member 22 can repeat the stamping operation.

[0060] See also Figure 6 and Figure 7 The stamping member 22 includes a sliding body 221 movably connected to the pressing member 21 and a stamping body 222 detachably connected to the sliding body 221. The sliding body 221 is roughly block-shaped, and the sliding body 221 is slidably disposed in the inclined guide hole 211 and has two receiving grooves 2211. The two receiving grooves 2211 are spaced apart and disposed on one side of the sliding body 221 facing the carrier 113 of the carrier 11 and respectively accommodate the corresponding first elastic member 23. The stamping body 222 is roughly rod-shaped, and the stamping body 222 is disposed at one end of the sliding body 221 facing the carrier 113 of the carrier 11 and detachably connected to the sliding body 221. The stamping body 222 is movably penetrated in the inclined guide hole 211. Driven by the sliding body 221, the stamping body 222 extends out of the inclined guide hole 211 and stamps the workpiece 200.

[0061] In this way, by providing the receiving groove 2211 to accommodate the first elastic member 23, the receiving groove 2211 can limit the elastic force direction of the first elastic member 23, so that the first elastic member 23 always provides elastic force along the extension direction of the receiving groove 2211, thereby improving the stability of the elastic force provided by the first elastic member 23. In addition, the stamping body 222 and the sliding body 221 are detachably connected, so that the operator can easily replace different types of stamping bodies 222 to form different types of inclined bosses 201.

[0062] Please continue reading Figure 6 and Figure 7The pressing member 21 includes a pressing body 212 abutting against the first elastic member 23 and a guide body 213 embedded in the pressing body 212 . The clamping body 212 is roughly plate-shaped, and the clamping body 212 abuts against the first elastic member 23. The guide body 213 is roughly block-shaped. The guide body 213 is embedded in the clamping body 212 and is provided with a first guide hole 2131 and a second guide hole 2132. The second guide hole 2132 is adjacent to the supporting member 11 relative to the first guide hole 2131, and the inner diameter of the first guide hole 2131 is larger than the inner diameter of the second guide hole 2132. The first guide hole 2131 and the second guide hole 2132 are both inclined to the clamping direction of the upper mold assembly 20 and the lower mold assembly 10 and are connected to form an inclined guide hole 211. The first guide hole 2131 and the second guide hole 2132 respectively accommodate and guide the sliding body 221 and the stamping body 222. The guide body 213 and the clamping body 212 cooperate to clamp the workpiece 200 to the supporting body 113 of the supporting member 11.

[0063] In this way, by setting the inner diameter of the first guide hole 2131 to be larger than the inner diameter of the second guide hole 2132, when the sliding body 221 moves toward the supporting body 113 of the supporting member 11, it can abut against the bottom wall of the first guide hole 2131, thereby limiting the movement distance of the sliding body 221 and preventing the sliding body 221 from moving too far and causing the stamping part 22 to separate from the clamping part 21.

[0064] See also Figure 4 and Figure 8 The movable assembly 30 includes a movable member 31 movably connected to the clamping member 21, a second elastic member 32 connected to the movable member 31, a driving member 33 connected to the movable member 31, a fixing member 34 spaced apart from the driving member 33 and the punching member 35 movably connected to the fixing member 34. The movable member 31 is disposed on the side of the upper mold assembly 20 away from the lower mold assembly 10 and is movably connected to the clamping member 21. There are three second elastic members 32, and the three second elastic members 32 are spaced apart on the side of the movable member 31 facing the clamping member 21. One end of the second elastic member 32 is connected to the movable member 31, and the other end of the second elastic member 32 abuts against the clamping member 21. There are two driving members 33, and the two driving members 33 are spaced apart on both sides of the fixing member 34 along the vertical direction of the clamping direction of the upper mold assembly 20 and the lower mold assembly 10, that is, Figure 8In the X-axis direction shown, each driving member 33 is connected to the movable member 31 and drives the stamping member 22 to move close to the supporting member 11. The fixed member 34 is roughly block-shaped. The fixed member 34 and the driving member 33 are spaced apart on the movable member 31. The fixed member 34 is provided with an inclined guide groove 341. The inclined guide groove 341 is inclined to the clamping direction of the upper mold assembly 20 and the lower mold assembly 10, and the extension direction of the inclined guide groove 341 intersects with the extension direction of the inclined guide hole 211. One end of the punching member 35 abuts against the inclined surface of the bottom of the inclined guide groove 341, and the other end of the punching member 35 movably penetrates into the stamping member 22 and is coaxially arranged with the stamping member 22. The movable member 31 moves close to the supporting member 11, so that the punching member 35 slides relative to the fixed member 34 in the inclined guide groove 341 and extends out of the stamping member 22 to stamp out the inclined boss 201, so as to form an inclined hole 202 on the inclined boss 201. Exemplarily, the movable member 31 is connected to an external driving member 33, which enables the movable member 31 to move close to the lower mold assembly 10. The driving member 33 may be a cylinder or a nitrogen spring.

[0065] In this way, when the pressing member 21 is arranged on the carrier 11, the movable member 31 moves in the direction close to the carrier 11, so that the second elastic member 32 can apply a thrust to the pressing member 21, so that the pressing member 21 presses the workpiece 200 onto the lower die assembly 10, and the second elastic member 32 and the pressing member 21 are flexibly abutted, so as to avoid excessive thrust applied to the pressing member 21 by the movable assembly 30, so as to cause damage to the workpiece 200 by the pressing member 21, which is conducive to ensuring the quality of the workpiece 200. In addition, the driving member 33 drives the stamping member 22 to move close to the carrier 11, so that the stamping member 22 quickly stamps the workpiece 200 to form the inclined boss 201, thereby improving the stamping efficiency. In addition, by setting one end of the punching member 35 to abut against the inclined surface of the bottom of the inclined guide groove 341, when the stamping member 22 completes the forming operation of the inclined boss 201, the movable member 31 drives the fixed member 34 to continue to move toward the supporting member 11, so that the punching member 35 slides relative to the fixed member 34 in the inclined guide groove 341 and extends out of the stamping member 22, and then the punching member 35 punches out the inclined hole 202 on the inclined boss 201.

[0066] See also Figure 8 and Fig. 9The movable member 31 includes a connecting body 311 movably connected to the pressing member 21 and a movable body 312 detachably connected to the connecting body 311. The connecting body 311 is roughly plate-shaped, and the connecting body 311 is movably connected to the pressing member 21. The driving member 33 and the fixing member 34 are arranged at intervals on the side of the connecting body 311 facing the pressing member 21. The connecting body 311 is provided with a connecting groove 3111 and a receiving groove 3112 in sequence along the direction from the upper mold assembly 20 to the lower mold assembly 10. The inner diameter of the connecting groove 3111 is larger than the inner diameter of the receiving groove 3112. One end of the second elastic member 32 is arranged in the connecting groove 3111, and the other end of the second elastic member 32 extends out of the receiving groove 3112. The movable body 312 is roughly plate-shaped, and the movable body 312 is detachably connected to the connecting body 311.

[0067] In this way, by providing a detachable connection between the movable body 312 and the connecting body 3311 , it is convenient for the operator to assemble the second elastic member 32 into the connected connecting groove 3111 and the receiving groove 3112 , thereby simplifying the mechanical structure of the movable component 30 .

[0068] See also Figure 8 The second elastic member 32 includes a supporting body 321 movably provided in the receiving groove 3112 and an elastic body 322 abutting against the supporting body 321. The supporting body 321 includes a supporting portion 3211 movably provided in the receiving groove 3112 and a stopper 3212 connected to the supporting portion 3211. The supporting portion 3211 is generally rod-shaped, the supporting portion 3211 is movably provided in the receiving groove 3112 and abuts against the pressing member 21, the stopper 3212 is generally disc-shaped, the stopper 3212 is located in the connecting groove 3111 and connected to one end of the supporting portion 3211 away from the pressing member 21, and the stopper 3212 abuts against the bottom of the connecting groove 3111 to limit the supporting portion 3211. The elastic force direction of the elastic body 322 is parallel to the mold closing direction, and the two ends of the elastic body 322 elastically resist the stopper 3212 and the movable body 312 respectively. Exemplarily, the elastic body 322 can be a spring.

[0069] In this way, by setting the two ends of the elastic body 322 to elastically resist the stop part 3212 and the movable body 312 respectively, when the thrust applied by the movable body 312 to the clamping member 21 through the second elastic member 32 is too large, the clamping member 21 applies a force to the resisting part 3211 in the reverse direction, so that the resisting part 3211 drives the stop part 3212 to compress the elastic body 322 to the movable body 312, so that the elastic body 322 eliminates the excessive thrust applied by the movable body 312 to the clamping body 212, which is beneficial to ensure the quality of the workpiece 200. In addition, since the inner diameter of the connecting groove 3111 is larger than the inner diameter of the receiving groove 3112, by respectively receiving the supporting portion 3211 and the stopping portion 3212 into the receiving groove 3112 and the connecting groove 3111, when the compressed elastic body 322 provides elastic force to drive the supporting body 321 to reset, the stopping portion 3212 can be abutted against the bottom of the connecting groove 3111, thereby limiting the supporting body 321 and preventing the supporting body 321 and the movable body 312 from loosening from each other, thereby ensuring the stable operation of the movable component 30.

[0070] Please continue reading Figure 8 The punching member 35 includes a moving body 351 slidably disposed in the oblique guide groove 341 and a punching body 352 connected to the moving body 351. The moving body 351 is roughly block-shaped, and is slidably disposed in the oblique guide groove 341 and abuts against the groove bottom oblique surface of the oblique guide groove 341. When the movable member 31 moves toward the direction of the carrier 11, the moving body 351 moves along the oblique direction of the oblique guide groove 341. The punching body 352 is roughly rod-shaped, and is arranged obliquely to the mold closing direction of the upper mold assembly 20 and the lower mold assembly 10. One end of the punching body 352 is connected to the moving body 351, and the other end of the punching body 352 is movably penetrated in the stamping member 22 and is coaxially arranged with the stamping body 222 of the stamping member 22. The punching body 352 extends out of the stamping member 22 under the drive of the moving body 351 and stamps and forms the oblique boss 201, so as to form the oblique hole 202 on the oblique boss 201.

[0071] In this way, by setting the movable body 351 to abut against the inclined surface of the bottom of the inclined guide groove 341, when the movable part 31 moves toward the supporting part 11, the movable body 351 can move in the inclined direction of the inclined guide groove 341, thereby driving the punching body 352 to extend out of the stamping part 22 and punch the inclined boss 201, thereby forming the inclined hole 202 on the inclined boss 201.

[0072] The working process of the above-mentioned stamping die 100 is roughly as follows:

[0073] First, the workpiece 200 is placed on the carrier 11, the pressing member 21 is arranged on the carrier 11 and abuts against the workpiece 200, the movable member 31 moves close to the carrier 11 and flexibly presses the pressing member 21 through the second elastic member 32, so that the pressing member 21 presses the workpiece 200 to the carrier 11, preventing the workpiece 200 from shaking or deflecting during the subsequent stamping operation, thereby improving the stamping accuracy;

[0074] Then, the driving member 33 drives the punching member 22 to move in a direction close to the carrier 11 under the guidance of the inclined guide hole 211, so that the punching member 22 quickly punches the workpiece 200 to form an inclined boss 201 on the surface of the workpiece 200, and the blade member 12 is pressed against the workpiece 200 to retract into the carrier 11 and compress the third elastic member 13 to the carrier 11;

[0075] Next, the movable member 31 drives the fixed member 34 to continue to move closer to the bearing member 11, so that the punching member 35 slides relative to the fixed member 34 in the inclined guide groove 341 and extends out of the stamping member 22, and then the punching member 35 is inserted into the blade member 12, and cooperates with the blade member 12 to punch out the inclined hole 202 on the inclined boss 201, so that the stamping and forming operation of the inclined boss 201 and the inclined hole 202 is completed at one time, without the need for secondary positioning and forming, thereby improving the stamping accuracy;

[0076] Finally, the movable member 31 drives the pressing member 21 to move in a direction away from the carrier 11 , and the compressed third elastic member 13 provides elastic force to drive the blade member 12 to push the workpiece 200 away from the carrier 11 , so as to complete the demoulding operation.

[0077] In the above-mentioned stamping die 100, the second elastic member 32 is driven by the movable member 31 to push the clamping member 21 to the carrier 11, so that the clamping member 21 flexibly presses the workpiece 200 to the carrier 11, avoids damage to the workpiece 200 and fixes the workpiece 200 on the carrier 11, prevents the workpiece 200 from shaking or shifting during the subsequent stamping process, and then the workpiece 200 is stamped and formed with the inclined boss 201 and the inclined hole 202 in turn through the stamping member 22 and the punching member 35, so that the stamping and forming operation of the workpiece 200 can be completed in one time, without the need for secondary positioning and forming, thereby improving the stamping accuracy.
