Description

Technical Field

[0001] This application relates to the field of stamping tooling technology, and more specifically, to stamping apparatus. Background Technology

[0002] The stamping devices in related technologies have technical problems such as complex structure and inconvenient operation. Utility Model Content

[0003] This application provides a stamping device to solve the technical problems of complex structure and inconvenient operation of stamping devices in related technologies.

[0004] The embodiments of this application are implemented as follows: In a first aspect, this application provides a stamping apparatus, including a lower die, an upper die, a locking assembly, and a stamping assembly. The lower die has a first clamping portion with a first through hole. The upper die and the lower die are spaced apart along a first direction. The upper die has a second clamping portion on its side facing the lower die, with a second through hole. A receiving space is formed between the first clamping portion and the second clamping portion, the receiving space connecting the first through hole and the second through hole, and the receiving space is used to receive a product. The locking assembly connects the upper die and the lower die, and the locking assembly is used to move the upper die toward the lower die so that the first clamping portion and the second clamping portion clamp the product. The stamping assembly includes a stamping rod and a stamping head. The stamping rod is rotatably connected to the upper die or the lower die, and the stamping head is connected to the stamping rod. The stamping head is movably inserted through the second through hole along the first direction, and the stamping rod is used to drive the stamping head through the second through hole to stamp the product.

[0005] According to the stamping apparatus of this application, before stamping begins, the workpiece is placed in the first clamping part of the lower die. A locking assembly moves the upper die toward the lower die, causing the first and second clamping parts to engage and fix the workpiece within the receiving space, thus maintaining its position. After stamping begins, applying a force to the end of the stamping rod away from the stamping head moves the stamping head toward the second through hole in a first direction. During this movement, the stamping head is pressed, and after passing through the receiving space, it reaches the second through hole, separating the part of the workpiece corresponding to the second through hole from the workpiece body, thus completing the stamping of the workpiece. Subsequently, applying a force in the opposite direction to the stamping rod moves the stamping head to the position received within the second through hole. The locking assembly then unlocks the upper and lower dies to install the next workpiece, or moves the next position of the workpiece to be stamped into the receiving space.

[0006] Thus, the stamping device of this application can reliably lock the upper and lower dies through the locking assembly, improving stamping accuracy; simultaneously, the second through hole can guide the stamping head, further improving the stamping accuracy of the stamping head. The cooperation between the stamping head, the first through hole, and the second through hole improves the mutual coordination between the various components, achieving a compact structure for the stamping device. The connection and cooperation between the stamping rod and the upper or lower die further enhances the overall ease of operation of the stamping device.

[0007] In one possible implementation: The locking assembly includes a support member and a handle. One end of the support member is connected to the lower mold, and the other end of the support member passes through the upper mold along a first direction and forms a connecting end. The handle has an abutment end and a gripping end spaced apart along its length. The abutment end is rotatably connected to the connecting end via a first pivot, and the outer peripheral surface of the abutment end abuts against the upper mold. The outer peripheral surface of the abutment end has a first contact point and a second contact point, which are spaced apart along the outer peripheral surface of the abutment end. From the first contact point to the second contact point, the distance between the outer peripheral surface of the abutment end and the first pivot gradually decreases.

[0008] In one possible implementation: The upper mold has a top surface on the side opposite to the lower mold along the first direction; when the second contact point abuts against the top surface, the tangent of the outer peripheral surface of the abutting point at the second contact point is parallel to the top surface.

[0009] In one possible implementation: The locking assembly includes a first limiting portion, one end of which is connected to the handle, and the other end of which extends in a direction away from the handle. When the first contact point abuts against the upper mold, the first limiting portion abuts against the upper mold in a first direction; and / or, the locking assembly includes a second limiting portion, one end of which is connected to the handle, and the other end of which extends in a direction away from the handle. When the second contact point abuts against the upper mold, the second limiting portion abuts against the upper mold in a first direction.

[0010] In one possible implementation: The stamping device further includes a first reset member, which is connected to the upper die and the lower die. The first reset member is used to drive the upper die to move away from the lower die in a first direction, and push the abutment to rotate through the upper die, so that the contact point between the abutment and the upper die moves from the first contact point toward the second contact point.

[0011] In one possible implementation: The stamping device further includes a limiting member that extends along a first direction. One end of the limiting member is connected to the lower die, and the limiting member passes through the upper die. The other end of the limiting member is located on the side of the upper die away from the lower die. When the second contact point abuts against the upper die, the upper die abuts against the end of the limiting member away from the lower die.

[0012] In one possible implementation: The stamping device further includes a third limiting part, which is disposed on the lower die and extends toward the upper die along a first direction. The third limiting part is used to abut against the upper die to limit the minimum distance between the upper die and the lower die.

[0013] In one possible implementation: One end of the stamping rod along its length is rotatably connected to the upper die or the lower die. A groove is formed in the middle of the stamping rod, and the groove extends along the length of the stamping rod. The stamping assembly also includes a second pivot, which is movably disposed in the groove along the length of the groove. The second pivot is connected to the stamping head.

[0014] In one possible implementation: The stamping head also includes a connecting block, one end of which is connected to the upper die, and the other end of which extends away from the lower die. The end of the stamping rod connected to the stamping head is rotatably connected to the portion of the connecting block that extends out of the upper die.

[0015] In one possible implementation: The stamping head has an initial position and a limit position. When the stamping head is in the initial position, it is completely received in the second through hole. When the stamping head is in the limit position, one end of the stamping head extends into the first through hole. The stamping device also includes a second reset member, which connects the upper die and the stamping head. The second reset member is used to apply a force to the stamping head in a first direction away from the lower die, so that the stamping head moves from the limit position to the initial position.

The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.

[0028] Some embodiments of this application are described in detail. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0029] See Figure 1 and Figure 2 This embodiment provides a stamping device 100, including a lower die 10, an upper die 20, a locking assembly 30, and a stamping assembly 40. The lower die 10 is provided with a first clamping part 11, and the first clamping part 11 has a first through hole K1. The upper die 20 and the lower die 10 are spaced apart along a first direction X. The side of the upper die 20 facing the lower die 10 is provided with a second clamping part 21, and the second clamping part 21 has a second through hole K2. A receiving space Q is formed between the first clamping part 11 and the second clamping part 21, and the receiving space Q connects the first through hole K1 and the second through hole K2. The receiving space Q is used to receive a product 200. The locking assembly 30 connects the upper die 20 and the lower die 10. The locking assembly 30 is used to drive the upper die 20 to move toward the lower die 10 so that the first clamping part 11 and the second clamping part 21 clamp the product 200. The stamping assembly 40 includes a stamping rod 41 and a stamping head 42. The stamping rod 41 is rotatably connected to the upper die 20 or the lower die 10. The stamping head 42 is connected to the stamping rod 41 and is movably inserted into the second through hole K2 along the first direction X. The stamping rod 41 is used to drive the stamping head 42 through the second through hole K2 to stamp the product 200.

[0030] According to the stamping device 100 of this embodiment, see [link to embodiment 100]. Figure 1 Before stamping begins, the workpiece is placed in the first clamping part 11 of the lower die 10. The locking assembly 30 moves the upper die 20 toward the lower die 10, causing the first clamping part 11 and the second clamping part 21 to engage and fix the workpiece within the accommodating space Q, thus maintaining the workpiece in a fixed position. (See also...) Figure 3 and Figure 4After stamping begins, applying a force to the end of the stamping rod 41 away from the stamping head 42 causes the stamping head 42 to move along the first direction X towards the second through hole K2. During this movement, stamping is performed, and the workpiece reaches the second through hole K2 after passing through the receiving space Q, thus separating the part of the workpiece corresponding to the second through hole K2 from the workpiece body, completing the stamping of the workpiece. Afterwards, applying a force in the opposite direction to the stamping rod 41 causes the stamping head 42 to move to the position received in the second through hole K2. Then, the upper die 20 and lower die 10 are unlocked by the locking assembly 30 to install the next workpiece, or to move the next position of the workpiece to be stamped into the receiving space Q.

[0031] Thus, the stamping device 100 of this application can reliably lock the upper die 20 and the lower die 10 through the locking assembly 30, improving stamping accuracy; at the same time, the second through hole K2 can guide the stamping head 42, further improving the stamping accuracy of the stamping head 42. The cooperation of the stamping head 42, the first through hole K1, and the second through hole K2 improves the mutual cooperation between the various components, achieving a compact structure for the stamping device 100. The connection and cooperation between the stamping rod 41 and the upper die 20 or the lower die 10 further improves the overall ease of operation of the stamping device 100.

[0032] In some embodiments, see Figure 4 and Figure 5 The locking assembly 30 includes a support member 31 and a handle 32. One end of the support member 31 is connected to the lower mold 10, and the other end of the support member 31 passes through the upper mold 20 along the first direction X and forms a connecting end 311. The handle 32 has an abutment end 321 and a gripping end 322 spaced apart along its length direction. The abutment end 321 is rotatably connected to the connecting end 311 via a first pivot 35, and the outer peripheral surface P2 of the abutment end 321 abuts against the upper mold 20. The outer peripheral surface P2 of the abutment end 321 has a first contact point P3 and a second contact point P4 (see [reference]). Figure 5 The first contact point P3 and the second contact point P4 are spaced apart along the outer peripheral surface P2 of the abutment tip 321. From the first contact point P3 to the second contact point P4, the distance between the outer peripheral surface P2 of the abutment tip 321 and the first pivot 35 gradually decreases. By operating the grip end 322 to rotate the handle 32, the abutment tip 321 rotates relative to the connecting end 311. As the handle 32 rotates and the contact point between the abutment tip 321 and the top surface P1 moves from the first contact point P3 to the second contact point P4, the upper mold 20 moves relative to the support member 31 towards the lower mold 10 along the first direction X, driven by the abutment tip 321. This allows the upper mold 20 to move closer to the lower mold 10 until the abutment tip 321 abuts against the upper mold 20 through the second contact point P4, thus achieving the pressing of the upper mold 20.

[0033] In some embodiments, see Figure 6 The upper mold 20 has a top surface P1 on the side opposite to the lower mold 10 along the first direction X. When the second contact point P4 abuts against the top surface P1, the tangent of the outer peripheral surface P2 of the abutment tip 321 at the second contact point P4 is parallel to the top surface P1. Thus, after the second contact point P4 contacts the top surface P1, a dead point is formed between the abutment tip 321 and the upper mold 20, thereby allowing the locking assembly 30 to keep the second contact point P4 abutting against the top surface P1, ensuring the locking effect.

[0034] In some embodiments, when the first contact point P3 abuts against the top surface P1, the tangent of the outer peripheral surface P2 of the abutment tip 321 at the first contact point P3 is parallel to the top surface P1. Thus, after the first contact point P3 contacts the top surface P1, a dead point is formed between the abutment tip 321 and the upper mold 20, thereby allowing the locking assembly 30 to keep the first contact point P3 abutting against the top surface P1, avoiding the risk of accidental contact causing the locking assembly 30 to rotate.

[0035] It is understood that in this embodiment, the outer peripheral surface P2 of the abutment 321 and the top surface P1 form a line contact. The first contact point P3 and the second contact point P4 are both any points on the contact line between the outer peripheral surface P2 of the abutment 321 and the top surface P1.

[0036] In some embodiments, see Figure 5 The handle 32 includes a connecting rod 323 and a cam 321a. One end of the connecting rod 323 is connected to the cam 321a. The cam 321a is configured as abutting point 321. The middle part of the cam 321a is rotatably connected to the connecting end 311 via a first pivot 35. The other end of the connecting rod 323 is configured as a gripping end 322. The cam 321a ensures that the abutting point 321 is in a dead position when the first contact point P3 abuts against the top surface P1 or the second contact point P4 abuts against the top surface P1.

[0037] In some embodiments, see Figure 1 The locking assembly 30 includes a first limiting portion 33. One end of the first limiting portion 33 is connected to the handle 32, and the other end of the first limiting portion 33 extends in a direction away from the handle 32. When the first contact point P3 abuts against the upper mold 20, the first limiting portion 33 abuts against the upper mold 20 along the first direction X. In this way, by the first limiting portion 33 abutting against the upper mold 20 along the first direction X, the abutting point 321 can be kept at the dead point position where the first contact point P3 contacts the top surface P1.

[0038] In some embodiments, see Figure 4The locking assembly 30 includes a second limiting portion 34. One end of the second limiting portion 34 is connected to the handle 32, and the other end of the second limiting portion 34 extends in a direction away from the handle 32. When the second contact point P4 abuts against the upper mold 20, the second limiting portion 34 abuts against the upper mold 20 in the first direction X. In this way, by the second limiting portion 34 abutting against the upper mold 20 in the first direction X, the abutting point 321 can be kept at the dead point position where the second contact point P4 contacts the top surface P1.

[0039] In some embodiments, see Figure 5 The connecting rod 323 includes a first rod segment 3231 and a second rod segment 3232. One end of the first rod segment 3231 is connected to the gripping end 322. One end of the second rod segment 3232 is connected to the other end of the first rod segment 3231. The other end of the second rod segment 3232 is connected to the abutment end 321. A first limiting part 33 is connected to the second rod segment 3232 and extends in a direction perpendicular to the length direction of the second rod segment 3232. A second limiting part 34 is connected to the second rod segment 3232 and extends in the opposite direction to the first limiting part 33.

[0040] Optionally, there are two second rod segments 3232. The two second rod segments 3232 are spaced apart. The first limiting part 33 and the second limiting part 34 are connected between the two second rod segments 3232. Each end of the two second rod segments 3232 opposite to the first rod segment 3231 is connected to a cam 321a. The two cams 321a together form the abutment 321. The support member 31 passes between the two cams 321a and is rotatably connected to the two cams 321a. In this way, the overall structural reliability of the locking assembly 30 can be improved.

[0041] In other embodiments, the locking assembly 30 may also employ a snap-locking structure, a threaded locking structure, or other locking structures.

[0042] In some embodiments, see Figure 2 The stamping device 100 also includes a first reset member 50. The first reset member 50 is connected to the upper die 20 and the lower die 10. The first reset member 50 is used to drive the upper die 20 to move away from the lower die 10 along the first direction X, and push the abutment 321 to rotate through the upper die 20, so that the contact point between the abutment 321 and the upper die 20 moves from the first contact point P3 toward the second contact point P4.

[0043] After the operator rotates handle 32 to disengage the contact point between the abutment tip 321 and the upper mold 20 from the second contact point P4, the first reset member 50 can push the upper mold 20 to move, thereby causing the abutment tip 321 to rotate around the first pivot 35, so that the abutment tip 321 rotates to the first contact point P3 and contacts the upper mold 20. This improves the ease of operation.

[0044] Optionally, there may be multiple first reset members 50. These multiple first reset members 50 are arranged circumferentially around the support member 31. This improves the uniformity of the force exerted by the multiple first reset members 50 on the upper mold 20.

[0045] Optionally, the first reset member 50 may be configured as a first elastic member. The two ends of the first elastic member are elastically connected to the upper mold 20 and the lower mold 10, respectively. In other embodiments, the first reset member 50 may also be configured as a motor or cylinder, etc.

[0046] Optionally, see Figure 2 The lower mold 10 has a first limiting groove C2. The upper mold 20 has a second limiting groove C3. One end of the first elastic member extends into the first limiting groove C2. The other end of the first elastic member extends into the second limiting groove C3. The first limiting groove C2 and the second limiting groove C3 can limit the first elastic member and guide the contraction direction of the first elastic member.

[0047] In some embodiments, see Figure 6 The stamping device 100 also includes a guide member 70. The guide member 70 extends along a first direction X. One end of the guide member 70 is connected to the lower die 10. The other end of the guide member 70 passes through the upper die 20. The guide member 70 can guide the movement of the upper die 20 along the first direction X.

[0048] Optionally, the upper mold 20 has a first guide hole K3 extending along the first direction X. The guide member 70 passes through the first guide hole K3.

[0049] In some embodiments, see Figure 6 The stamping device 100 also includes a limiting member 80. The limiting member 80 extends along the first direction X, one end of the limiting member 80 is connected to the lower die 10, the limiting member 80 passes through the upper die 20, and the other end of the limiting member 80 is located on the side of the upper die 20 away from the lower die 10; when the second contact point P4 abuts against the upper die 20, the upper die 20 abuts against the end of the limiting member 80 away from the lower die 10.

[0050] Optionally, the upper mold 20 has a second guide hole K4 extending along the first direction X. The limiting member 80 passes through the second guide hole K4.

[0051] Specifically, see Figure 6 The limiting member 80 includes a limiting post 81 and a limiting flange 82. The limiting post 81 passes through the upper mold 20. One end of the limiting post 81 is connected to the lower mold 10. The other end of the limiting post 81 is located on the side of the upper mold 20 opposite to the lower mold 10 and is connected to the limiting flange 82. The limiting flange 82 extends along the projection of the first direction X to the outside of the fifth guide hole. A limiting flange 82 is formed at one end.

[0052] Optionally, the limiting post 81 includes a first fixing post 811 and a second fixing post 812. One end of the first fixing post 811 abuts against the lower mold 10. The other end of the first fixing post 811 extends to the side of the upper mold 20 opposite to the lower mold 10. A limiting flange 82 connects to the end of the first fixing post 811 opposite to the upper mold 20. The second fixing post 812 passes through the first fixing post 811 and is fixedly connected to the lower mold 10.

[0053] Optionally, there may be multiple limiting members 80 and multiple guide members 70. Multiple limiting members 80 are arranged around the support member 31. Multiple guide members 70 are arranged around the support member 31. This improves the guiding effect of the limiting members 80 and guide members 70 on the movement of the upper mold 20 along the first direction X.

[0054] In some embodiments, see Figure 1 The stamping device 100 also includes a third limiting part 12. The third limiting part 12 is provided on the lower die 10 and extends toward the upper die 20 along the first direction X. The third limiting part 12 is used to abut against the upper die 20 to limit the minimum distance between the upper die 20 and the lower die 10. In this way, the movement stroke of the upper die 20 along the first direction X can be prevented from being too large and damaging the product 200, thereby ensuring the protection of the product 200.

[0055] Optionally, there may be multiple third limiting parts 12. Multiple third limiting parts 12 are arranged around the support member 31.

[0056] Optionally, when the second contact point P4 contacts the top surface P1, the third limiting part 12 abuts against the upper mold 20.

[0057] In some embodiments, see Figure 1 The stamping rod 41 is rotatably connected to the upper die 20 or the lower die 10 at one end along its length. A groove C1 is formed in the middle of the stamping rod 41, and the groove C1 extends along the length of the stamping rod 41. The stamping assembly 40 also includes a second pivot 43, which is movably disposed in the groove C1 along its length and is connected to the stamping head 42.

[0058] Thus, during the rotation of the stamping rod 41 relative to the upper die 20 or the lower die 10 under force, the second pivot 43 is driven to move along the length direction of the stamping rod 41 and along the first direction X through the surface of the slide groove C1, thereby driving the stamping head 42 to move along the first direction X, so that the stamping head 42 moves closer to or further away from the lower die 10.

[0059] In other embodiments, the slide C1 may also be provided on the stamping head 42, and the second pivot 43 is connected to the stamping rod 41. Therefore, there are various structures that convert the rotation of the stamping rod 41 into the movement of the stamping head 42 along the first direction X, and this embodiment provides specific limitations on such structures.

[0060] In some embodiments, the stamping device 100 further includes a connecting block 22. One end of the connecting block 22 is connected to the upper die 20, and the other end of the connecting block 22 extends in a direction away from the lower die 10. The end of the stamping rod 41 connected to the stamping head 42 is rotatably connected to the portion of the connecting block 22 that extends out of the upper die 20.

[0061] Specifically, the stamping rod 41 is rotatably connected to the connecting block 22 via the third pivot 44.

[0062] In some embodiments, the stamping head 42 has an initial position and a limit position. See also Figure 2 When the stamping head 42 is in its initial position, it is fully contained within the second through hole K2. (See also...) Figure 7 When the stamping head 42 is in its extreme position, one end of the stamping head 42 extends into the first through hole K1. The stamping device 100 also includes a second reset member 60. The second reset member 60 connects the upper die 20 and the stamping head 42, and is used to apply a force to the stamping head 42 in the first direction X away from the lower die 10, so that the stamping head 42 moves from the extreme position to the initial position.

[0063] Thus, after the locking assembly 30 releases the upper die 20 to the lower die 10 and the operator releases the stamping rod 41, the second reset component 60 can drive the stamping head 42 to move to the initial position so that the next product 200 can be placed in.

[0064] Optionally, there may be multiple second reset members 60. These multiple second reset members 60 are circumferentially spaced around the second through hole K2. This improves the uniformity of the force applied to the stamping head 42 by the multiple second reset members 60.

[0065] Optionally, the second reset member 60 can be configured as a second elastic member. The two ends of the second elastic member are elastically connected to the upper die 20 and the stamping head 42, respectively. In other embodiments, the second reset member 60 can also be configured as a motor or cylinder, etc.
