Description

Technical Field

[0001] The invention relates to the technical field of crimping die equipment, and in particular to a wire harness crimping die. Background Art

[0002] In the field of wire harness production, wire harness crimping dies are an indispensable and important tool. Their performance and efficiency directly affect the overall quality and production cost of the wire harness. Traditional wire harness crimping die designs often have problems such as complex control of multiple power sources, large equipment space, and difficulty in ensuring crimping accuracy.

[0003] Traditional wire harness crimping dies are usually designed to independently design various functional modules such as crimping, positioning, and transmission, and each module may require a separate power source for control. For example, a Chinese patent (application number: 202221648632.5) discloses a shell pre-pressing die suitable for FAKRA signal transmission, including a base plate, a fixed seat, a fixed plate, a conveying mechanism, and a pressing mechanism. The fixed seat is installed at the upper rear end of the base plate, the fixed plate is installed at one end of the fixed seat, and the conveying mechanism is arranged on the fixed plate. The conveying mechanism includes a positioning component for limiting the position of the center terminal, and the conveying mechanism device also includes a driving component for driving the position of the center pin terminal to move. The driving mechanism is arranged above the positioning component; the utility model uses a predetermined device to not only ensure that the outer conductor will not move forward and backward when the center terminal is transmitted to the outer conductor terminal, and ensure the consistency of the center terminal transmitted to the outer conductor, but also ensure that the shielding net is completely pressed into the core wire crimping area, and can also ensure that the terminal working area and the crimping area after crimping are highly coaxial, so as to achieve good shielding of external interference signals.

[0004] When using the equipment, the terminal blocks need to be fixed, and then the wires are placed on the terminal blocks, and the connection between the terminal blocks and the wires is achieved by pressing the upper and lower molds. This design needs to provide at least two power sources, one of which is a power source for driving the upper and lower molds to perform the pressing operation, and the other power source is a pushing power source for pushing the terminal blocks forward. The two need to be closely coordinated and debugged during use to complete a crimping operation together, that is, after the previous crimping operation is completed, the upper and lower molds are separated, and then the pushing power source is started to push the next terminal block to the lower mold. Precise program setting and debugging are required between the two to effectively achieve the coordinated operation of crimping and feeding, which increases the difficulty of use and debugging of the entire equipment, and is extremely difficult for the subsequent replacement of wearing parts and equipment maintenance, increasing the cost of equipment maintenance. Summary of the invention

[0005] In order to solve the above problems, an embodiment of the present invention provides a wire harness crimping mold that can synchronously realize crimping and terminal feeding through a single driving source. The overall equipment has a simple structure, is easy to debug and install, and can realize continuous crimping operations without complicated program settings. It can effectively improve work efficiency and reduce subsequent maintenance costs.

[0034] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

The feeding claw 7 slides along the length direction of the pressing plate 6, driving the terminal to move toward the crimping lower die 4, so as to facilitate the completion of the next crimping operation. A driving device for driving the feeding claw 7 to move back and forth is provided on the frame 2. A transmission assembly located between the lifting device and the driving device is provided on the frame 2. The transmission assembly can utilize the longitudinal movement of the crimping upper die 3 to drive the driving device to move synchronously, thereby realizing the feeding operation of the feeding claw 7, preparing for the next crimping operation, and realizing continuous crimping operation through a single driving source.

[0036] The transmission assembly includes a transmission shaft 8 that slides along the length direction of the frame 2. One end of the transmission shaft 8 is provided with a driving shaft 9 used in conjunction with the lifting device, and the other end is provided with a driven shaft 10 used in conjunction with the driving device. The driving shaft 9 will drive the transmission shaft 8 to move laterally under the action of the lifting device. At this time, the driven shaft 10 will slide laterally with the transmission shaft 8, thereby driving the driving device to operate and push the feeding claw 7 to move.

[0037] A sleeve 11 for mounting the transmission shaft 8 is provided on the frame 2. Avoidance grooves 12 corresponding to the positions of the driving shaft 9 and the driven shaft 10 are respectively provided at both ends of the sleeve 11. A return spring 13 sleeved on the outside of the transmission shaft 8 is provided in the middle of the sleeve 11. An adjusting sleeve 52 is provided on the outside of the end of the transmission shaft 11 close to the driving shaft 9. The adjusting sleeve is threadedly connected to the front half of the transmission shaft 8, and as the transmission shaft 8 slides in the sleeve 11, the end abuts against the return spring 13. The transmission shaft 8 is provided with an adjusting nut extending to the outside of the sleeve 11. The position of the transmission shaft 8 in the sleeve can be adjusted by using the adjusting nut 53, and then the position of the driven shaft 9 in the avoidance groove 12 can be fine-tuned to ensure that the feeding claw 7 can abut against the material and that the terminal can be accurately pushed to the crimping lower die 4 in preparation for the next crimping operation.

[0038] The lifting device includes a slider 14 for driving the crimping upper die 3 to move longitudinally, a hanging head 15 connected to an external power source is provided on the upper part of the slider 14, and the external power source adopts a lifting cylinder. A positioning hole 16 for installing the crimping upper die 3 is provided in the middle of the slider 14, and a bolt for fastening the crimping upper die 3 is provided in the positioning hole 16. A push plate 17 for driving the drive shaft 9 to move horizontally is provided on the back of the slider 14. The push plate 17 includes a translation part 36 and an extrusion part 37, and a push plate 17 is provided between the translation part 36 and the extrusion part 37. There is a transition portion 38, and the thickness of the push plate 17 gradually decreases from the extrusion portion 37 to the translation portion 36. When the entire device is in a stationary state, the drive shaft 9 fits the transition portion 38. At this time, the transmission shaft 8 moves to the left, driving the driven shaft 10 to slide to the left, and the feeding claw 7 abuts against the material. The terminal is located on the crimping lower die 4. At this time, the terminal will be placed on the terminal. The driving source drives the slider 14 to descend to start the crimping operation. At this time, the push plate 17 descends with the slider 14, and the drive shaft 9 moves from the extrusion portion 37 to the translation portion. At this time, the transmission shaft 8 moves to the right and resets under the action of the reset spring 13, and the feeding claw 7 moves to the left. After the crimping operation is completed, the slider 14 drives the push plate 17 to move upward. During the rising process of the slider 14, the contact position of the driving shaft 9 and the push plate 17 moves from the translation part 36 to the extrusion part 37. At this time, the transmission shaft 8 drives the driven shaft 10 to move to the left. Through the transmission of the driving device, the feeding claw 7 moves to the right, and the next terminal is pushed to the crimping lower die 4 to prepare for the next crimping operation. The driving source is used to drive the slider 14 to rise and fall, and the crimping operation is completed during the lifting process. At the same time, the cooperation of the transmission component is used to complete the pushing operation of the next terminal. Compared with the traditional material pushing and crimping operation completed by two driving sources, the present device only needs one driving source to complete it. While saving the driving source, it can also reduce the volume of the entire device, and there is no need to perform program debugging to complete the cooperation of multiple driving sources. The operation and adjustment operation are also simpler, and cost investment can be saved.

[0039] A lifting groove 18 corresponding to the position of the slider 14 is provided on the side wall of the frame 2, and pressure plates 19 are provided on both sides of the opening of the lifting groove 18. A storage groove 20 for installing the crimping upper mold 3 is reserved between the two pressure plates 19. The lifting groove 18 limits the two sides of the slider 14, and the pressure plate 19 can limit the front side of the slider 14 to ensure the smooth sliding of the slider 14 in the lifting groove 18.

[0040] The driving device includes a swing arm 21 and a driving arm 22. A rotating shaft 23 connected to the driven shaft 10 is provided in the middle of the swing arm 21. The upper part of the swing arm 21 is hinged to the driving arm 22. A card slot 24 is provided at the lower part of the swing arm 21. A pin located in the card slot 24 is provided on the side wall of the frame 2. The length of the card slot 24 is greater than the diameter of the pin. The lateral movement of the driven shaft 10 can drive the swing arm 21 to move left and right, and then drive the swing arm 21 to rotate with the driven shaft 10 in the middle as the fulcrum. A fixed seat 25 connected to the feeding claw 7 is provided at the lower part of the driving arm 22. A positioning plate 39 located outside the driving arm 22 is provided on the frame 2. An adjusting seat 40 connected to the driving arm 22 is provided on the positioning plate 39. The adjusting seat 40 includes a card shaft 41. The card shaft 41 is oriented toward the positioning A positioning shaft 42 is provided on one side of the plate 39, and the positioning shaft 42 is connected to the positioning plate 39 by a locking pin 43. One end of the locking pin 43 extends to the outside of the positioning plate and is provided with an indicator block 44. The positioning plate is provided with a scale 45 used in conjunction with the indicator block. A through groove 46 is provided on the side wall of the clamping shaft facing the driving arm 22, which is used to clamp the driving arm 22. The design of the adjustment seat can provide a rotating fulcrum in the middle when the driving arm 22 swings, and the height of the adjustment seat can be adjusted on the positioning plate. By adjusting the height of the rotating fulcrum, the ratio of the two rotating force arms of the driving arm 22 can be changed, and then the pushing distance of the lower end of the driving arm 22 can be adjusted, which is convenient for controlling the pushing distance of the material and ensuring that the terminal block can be pushed to the crimping lower die 4.

[0041] One end of the fixed seat 25 is hinged to the driving arm 22, and the other end is provided with a positioning groove 26 for installing the feeding claw 7. The fixed seat 25 can reciprocate with the swing of the driving arm 22, thereby driving the feeding claw 7 to move and push the material.

[0042] The feeding claw 7 includes a cross beam 27 installed in the positioning groove 26, a push plate 28 is provided at one end of the cross beam 27 facing outward, and a guide bracket 29 is provided at the other end to fit with the side wall of the pressing plate 6. The guide bracket 29 fits with the inner side wall of the pressing plate 6 to ensure the stability of the feeding claw 7 during movement.

[0043] The upper part of the push plate 28 is slidably connected to the cross beam 27, and a guide rod 48 is provided on the upper part of the push plate 28. A through hole 49 is provided at the end of the cross beam 27 for penetrating the guide rod 48, and a pressing spring 50 is provided in the middle of the through hole. A limiting boss 51 abutting against the upper end of the pressing spring is provided on the side wall of the guide rod, and a toggle tooth 30 for pushing the material forward is provided at the lower part. A guide roller 31 slidably connected to the pressure plate 6 is provided on the inner side wall of the middle part of the push plate 28, and a track groove 32 for raising the longitudinal height of the guide roller 31 is provided on the side wall of the pressure plate 6. By raising the height of the guide roller 31, the push plate 28 is lifted in height when it moves to the left, so as to avoid the next material from being deflected when moving toward the crimping lower die after being scratched with the material plate for installing the terminal block.

[0044] The track groove 32 includes a lifting section 33, a falling section 34 and a translation section 35 which are sequentially distributed along the movement trajectory of the guide roller 31. A reset gap 47 is provided at one end of the translation section 35 facing the lifting section 34. When the guide roller moves to the left to the end of the translation section 35, the guide roller 31 will move upward to the end of the lifting section 33 under the action of the pressing spring 50. The design of the reset gap 47 can ensure that the guide roller 31 can smoothly enter the lifting section 33, and avoid contact with the large mounting plate of the material when moving to the right, that is, there is a height lift in the process of the push plate moving to the right, so as to avoid scratching the material plate used to install the terminal block, thereby ensuring that the material will not be deflected, twisted, etc. due to external force intervention during the entire pushing process, thereby improving the stability of the feeding.
