[0036] In the embodiments of the present application, with reference to Figures 1 to 10 , the present application provides a crimping die 100, which is applied to realize the crimping between bulk terminals and wires.

[0037] Specifically, the crimping die 100 has a first direction Z, a second direction X, and a third direction Y that intersect pairwise. Exemplarily, the crimping die 100 has a first direction Z, a second direction X, and a third direction Y that are perpendicular to each other pairwise. Herein, "perpendicular" refers to a state where the angle formed by a straight line and a straight line, a straight line and a plane, or a plane and a plane is 89° to 91°.

[0039] Specifically, the upper die assembly 110 includes: a first die base 111; the lower die assembly 120 includes: a second die base 121 and a guide post 122. The guide post 122 is disposed on the second die base 121 and extends along the first direction Z. The first die base 111 is movably inserted through the guide post 122, that is, the first die base 111 can move freely along the guide post 122, and the first die base 111 and the second die base 121 are oppositely disposed in the first direction Z; the first crimping unit 130 is detachably disposed on one side of the first die base 111 close to the second die base 121; the second crimping unit 140 is detachably disposed on one side of the second die base 121 close to the first die base 111.

[0040] It can be understood that the existing crimping die is of an integral design. When the die needs to be replaced, the entire set of dies needs to be disassembled, and then the new die needs to be transported and installed. As a result, the debugging steps during the production changeover process are very cumbersome, consuming a large amount of time in the debugging steps. Moreover, the die is relatively heavy (>7 kg), inconvenient to disassemble and assemble, and inconvenient for manual handling, with poor flexibility, resulting in a long die replacement cycle.

[0041] In this application, by detachably disposing the first crimping unit 130 on the first die base 111 and the second crimping unit 140 on the second die base 121, it is ensured that the first crimping unit 130 and the second crimping unit 140 can be quickly replaced according to production requirements without replacing the entire die, facilitating the die replacement operation for the staff, saving the die replacement time required for production changeover, improving the die replacement efficiency, enhancing the flexibility of the crimping die, and effectively reducing the total die cost during part production.

[0042] In one embodiment, refer to Figures 1 to 2 、 Figures 7 to 9, the first crimping unit 130 includes: a first template 131, a first plastic knife 132, and a first guide knife 133. The first template 131 is detachably arranged on one side of the first die base 111 close to the second die base 121 to ensure the overall disassembly of the first crimping unit 130 by disassembling the first template 131. The first plastic knife 132 and the first guide knife 133 are both connected to one side of the first template 131 close to the second crimping unit 140, and the first plastic knife 132 and the first guide knife 133 are arranged in sequence in the second direction X.

[0043] Among them, the first plastic knife 132 and the first guide knife 133 are fixedly connected to the first template 131 by bolts.

[0044] Refer to Figures 1 to 2 , Figure 10 , the second crimping unit 140 includes: a second template 141, a second plastic knife 142, and a second guide knife 143. The second template 141 is detachably arranged on one side of the second die base 121 close to the first die base 111 to ensure the overall disassembly of the second crimping unit 140 by disassembling the second template 141. The second plastic knife 142 and the second guide knife 143 are both connected to one side of the second template 141 close to the first crimping unit 130, and the second plastic knife 142 and the second guide knife 143 are arranged in sequence in the second direction X. The second plastic knife 142 and the first plastic knife 132 are arranged opposite to each other in the first direction Z, and the second guide knife 143 and the first guide knife 133 are arranged opposite to each other in the first direction Z to ensure that when the crimping die 100 performs a crimping operation on components, the second plastic knife 142 and the first plastic knife 132 cooperate with each other, and the second guide knife 143 and the first guide knife 133 cooperate with each other to realize the crimping of the components.

[0045] Specifically, when it is necessary to crimp a wire and a bulk terminal, the wire and the bulk terminal to be crimped can be placed on the second plastic knife 142 and the second guide knife 143, and the first die base 111 is controlled to move in the first direction Z towards the second die base 121, so as to drive the first plastic knife 132 to approach the second plastic knife 142 and drive the first guide knife 133 to approach the second guide knife 143 by using the first die base 111, so that the crimping cavities between the second plastic knife 142 and the first plastic knife 132 and between the second guide knife 143 and the first guide knife 133 are closed, and the crimping operation of the wire and the bulk terminal is realized.

[0046] After the crimping is completed, the first die base 111 is controlled to move in the first direction Z away from the second die base 121, so as to drive the first plastic knife 132 to move away from the second plastic knife 142 and drive the first guide knife 133 to move away from the second guide knife 143 by using the first die base 111, and the workpiece after crimping is taken out.

[0047] In an embodiment, refer to Figure 2, a first die holder 111 is provided with a first card slot 1111 that extends along a second direction X. A first card-connecting portion 1311 is provided on a first template 131, and the first card-connecting portion 1311 extends along the second direction X. The first card-connecting portion 1311 is engaged with the first card slot 1111 to detachably connect the first template 131 to the first die holder 111.

[0048] Specifically, when it is necessary to disassemble the first crimping unit 130, the staff can control the first card-connecting portion 1311 of the first template 131 to slide along the first card slot 1111, so as to engage the first template 131 with the first die holder 111, or separate the first template 131 from the first die holder 111.

[0049] In this application, the detachable connection between the first template 131 and the first die holder 111 is realized through the cooperation of the first card-connecting portion 1311 and the first card slot 1111. The structure is simple, which is convenient for the staff to perform die-changing operations, saves the die-changing time required for production changeovers, improves the die-changing efficiency, and is also convenient for processing and forming.

[0050] In one embodiment, referring to Figures 4 to 5 , the first die holder 111 is further provided with a first receiving groove 1112 and a first unlocking groove 1113, and the first receiving groove 1112 communicates with the first unlocking groove 1113; a first locking groove 1312 is provided on the first template 131, and the notch of the first locking groove 1312 and the notch of the first unlocking groove 1113 are oppositely arranged in a first direction Z.

[0051] The upper die assembly 110 further includes: a first rotating shaft 112 and a first cam 113. At least part of the first rotating shaft 112 is disposed in the first receiving groove 1112 to make the overall structure compact and occupy a small floor space; the first cam 113 is disposed at one end of the first rotating shaft 112 close to the first locking groove 1312.

[0052] The first rotating shaft 112 drives the first cam 113 to be selectively located in the first locking groove 1312 or the first unlocking groove 1113 to realize the locking and unlocking between the first template 131 and the first die holder 111, and further realize the locking and unlocking between the first crimping unit 130 and the first die holder 111.

[0053] Specifically, the first crimping unit 130 has two states of locking and unlocking. When the first template 131 is fixed on the first die holder 111, the staff can drive the first rotating shaft 112 to rotate clockwise to drive the first cam 113 to rotate clockwise synchronously. When the first cam 113 rotates to the first locking groove 1312, at this time, the first crimping unit 130 is in a locked state, and no relative displacement can occur between the first crimping unit 130 and the first die holder 111, and the crimping die 100 can perform crimping operations at this time.

[0054] When the die of the crimping die 100 needs to be changed, the staff can drive the first rotating shaft 112 to rotate counterclockwise, so as to drive the first cam 113 to rotate counterclockwise synchronously. When the first cam 113 rotates to the first unlocking groove 1113, at this time, the first crimping unit 130 is in the unlocking state, and the staff can control the first clamping portion 1311 of the first template 131 to slide along the first clamping groove 1111, so as to separate the first template 131 from the first die base 111, realizing the die change operation of the first crimping unit 130.

[0055] In one embodiment, the crimping die 100 further includes: a driving member 170, and the driving member 170 is detachably connected to the first rotating shaft 112. When the die of the crimping die 100 needs to be changed, the driving member 170 can be connected to the first rotating shaft 112, and the first rotating shaft 112 is driven to rotate by the driving member 170, so as to facilitate the staff to perform the die change operation and improve the die change efficiency.

[0056] In one embodiment, referring to Figures 1 to 4 , in order to ensure that the first crimping unit 130 is in the locked state, in the present application, a first sensing portion 1121 is provided at one end of the first rotating shaft 112 away from the first cam 113.

[0057] The upper die assembly 110 further includes: a first locking sensor 114, the first locking sensor 114 is disposed on a side of the first die base 111 close to the first sensing portion 1121, and the first locking sensor 114 is configured to sense the first sensing portion 1121.

[0058] Specifically, when the driving member 170 drives the first rotating shaft 112 to rotate clockwise, the first sensing portion 1121 rotates clockwise synchronously with the first rotating shaft 112. When the first locking sensor 114 senses the first sensing portion 1121, it indicates that the first cam 113 is located in the first locking groove 1312, and the first crimping unit 130 is in the locked state and does not need to be rotated continuously.

[0059] In the present application, through the cooperation between the first sensing portion 1121 and the first locking sensor 114, it is convenient for the staff to observe the real-time position of the first cam 113, so as to facilitate the staff to perform the die change operation and improve the die change efficiency.

[0060] Wherein, the first locking sensor 114 can be any one of a contact sensor or an infrared sensor, but is not limited thereto.

[0061] Specifically, in order to detect whether the first crimping unit 130 is installed in place, in the present application, the upper die assembly 110 further includes: a first limiting member 115 and a first position sensor 116; the first limiting member 115 is disposed on one side of the first die base 111 close to the first sensing portion 1121, and the first limiting member 115 is in contact connection with the first template 131; the first position sensor 116 is disposed on the first limiting member 115, and the first position sensor 116 is configured to sense whether the first crimping unit 130 is assembled in place.

[0062] Among them, the first locking sensor 114 can be a contact sensor, but is not limited thereto.

[0063] It can be understood that in the present application, the cooperation between the first limiting member 115 and the first template 131 is used to prevent the first crimping unit 130 from being over-installed, ensure that the first crimping unit 130 is installed in place, and at the same time, by arranging the first position sensor 116 on the first limiting member 115, when the first position sensor 116 senses the first template 131, it indicates that the first crimping unit 130 is installed in place, further improving the die change efficiency.

[0064] In an embodiment, referring to Figures 7 to 9 , a receiving groove 1313 is formed on the first template 131.

[0065] The first crimping unit 130 further includes: an adjusting knob 134, an adjusting member 135, and a pressing plate 136. The adjusting knob 134 and the adjusting member 135 are both disposed in the receiving groove 1313; a part of the adjusting member 135 passes through the adjusting knob 134 and is in transmission connection with the adjusting knob 134. Exemplarily, a part of the adjusting member 135 passes through the adjusting knob 134 and is screwed to the adjusting knob 134. Another part of the adjusting member 135 is in contact connection with the first plastic knife 132 and the first guide knife 133; the pressing plate 136 is connected to the notch of the receiving groove 1313, and the pressing plate 136 abuts against the adjusting knob 134;

[0066] Specifically, when it is necessary to adjust the positions of the first plastic knife 132 and the first guide knife 133, the staff can drive the adjusting knob 134. Since a part of the adjusting member 135 is screwed to the adjusting knob 134, and the pressing plate 136 limits the adjusting knob 134, a relative displacement occurs between the adjusting member 135 and the adjusting knob 134, and the adjusting member 135 moves in the first direction Z, thereby controlling the first plastic knife 132 and the first guide knife 133 to move in the first direction Z to adjust the relative positions of the first plastic knife 132 and the first guide knife 133 in the first direction Z, and adjusting the corresponding height according to the required wires and terminals, which is applicable to a variety of terminals and has versatility.

[0069] In this application, the second template 141 and the second die holder 121 are detachably connected through the cooperation of the second engaging portion 1411 and the second card slot 1211. The structure is simple, which is convenient for the staff to perform die change operations, saves the die change time required for production changeover, improves the die change efficiency, and is also convenient for processing and forming.

[0070] In an embodiment, referring to Figure 4 and Figure 6 , a second receiving groove 1212 and a second unlocking groove 1213 are formed on the second die holder 121, and the second receiving groove 1212 and the second unlocking groove 1213 are communicated; a second locking groove 1412 is formed on the second template 141, and the notch of the second locking groove 1412 and the notch of the second unlocking groove 1213 are oppositely arranged in the first direction Z.

[0071] The lower die assembly 120 further includes: a second rotating shaft 123 and a second cam 124. At least part of the second rotating shaft 123 is arranged in the second receiving groove 1212 to make the overall structure compact and occupy a small floor space; and the second cam 124 is arranged at one end of the second rotating shaft 123 close to the second unlocking groove 1213.

When the second cam 124 rotates to the second locking groove 1412, at this time, the second crimping unit 140 is in a locked state, and no relative displacement can occur between the second crimping unit 140 and the second die holder 121. The crimping die 100 can perform crimping operations at this time.

[0074] When the die of the crimping die 100 needs to be changed, the staff can drive the second rotating shaft 123 to rotate counterclockwise, so as to drive the second cam 124 to rotate counterclockwise synchronously. When the second cam 124 rotates to the second unlocking groove 1213, at this time, the second crimping unit 140 is in the unlocking state, and the staff can control the second clamping portion 1411 of the second template 141 to slide along the second clamping groove 1211, so as to separate the second template 141 from the second die base 121, and realize the die change operation of the second crimping unit 140.
