Description

Technical Field

[0001] This utility model relates to the field of wire harness processing technology, specifically to a dual-gun split-type terminal wire harness forming device. Background Technology

[0002] In modern electronic equipment and automotive manufacturing industries, terminal wire harnesses are key components for achieving electrical connections, and their forming quality directly affects the stability and reliability of equipment operation. Currently, traditional wire harnesses have loose wires before forming, making it impossible to twist them into a neat bundle before forming. This leads to problems such as looseness and misalignment during subsequent forming, seriously affecting forming accuracy and product quality. Therefore, this application is hereby submitted. Utility Model Content

[0003] This application proposes a dual-gun split-type terminal wire harness forming device to solve the technical problem in the prior art where the wires of the wire harness are in a loose state before forming, making it impossible to twist the loose wires into a regular wire harness before forming, which leads to the wire harness being prone to loosening and misalignment during subsequent forming. The above-mentioned technical objective of this utility model is achieved through the following technical solution: A dual-gun split-type terminal wire harness forming device includes a worktable, a primary forming mechanism, a secondary forming mechanism, and a fixing mechanism. The primary forming mechanism includes a first slide rail, a first slider, a support plate, a first pressure block, a first rod-type cylinder, a first rodless cylinder, a second pressure block, and a second slider. The support plate is disposed on the worktable, the first slide rail is disposed on the support plate, the first slider is slidably disposed on the first slide rail, the first rod-type cylinder is disposed on the support plate, the first pressure block is disposed on the output end of the first rod-type cylinder, the first pressure block is connected to the first slider, the first rodless cylinder is disposed on the worktable, the second slider is disposed on the first rodless cylinder, the second pressure block is disposed on the top of the second slider, and the first pressure block is located directly above the second pressure block.

[0004] Preferably, the secondary forming mechanism includes a base, a third cylinder, a lateral limiting block, a support frame, a fourth cylinder, and a vertical pressing block. The base is disposed on the worktable, the third cylinder is symmetrically disposed on the worktable, the lateral limiting blocks are disposed on the third cylinder, and the lateral limiting blocks are located on both sides of the base. The support frame is disposed on the worktable near the base, the fourth cylinder is disposed on the support frame, and the vertical pressing block is disposed on the output end of the fourth cylinder.

[0005] Preferably, the fixing mechanism includes a second rodless cylinder, a third slider, and a gripper. The second rodless cylinder is disposed on the worktable, the third slider is disposed on the second rodless cylinder, and the gripper is disposed on the top of the third slider.

[0006] Preferably, the base is provided with guide rails on both the left and right sides, and the lateral limiting block is slidably connected to the guide rails.

[0007] Preferably, both the first pressing block and the second pressing block are rubber pads.

[0008] Preferably, the support frame is provided with a guide mechanism, and the vertical pressure block is connected to the guide mechanism.

[0009] Compared with the prior art, the beneficial effects of this utility model include: In the initial forming mechanism, the cooperation between the first slide rail and the first slider, along with the precise vertical drive of the first rod-mounted cylinder, ensures that the first pressure block can stably and accurately align and press down with the second pressure block, applying a uniform clamping force to the wire harness. When the first rodless cylinder drives the second slider and the second pressure block to reciprocate, this stable clamping ensures that all parts of the wire harness experience consistent force during twisting, resulting in a wire harness of uniform thickness and regular shape from loose wires. This provides a high-precision foundation for subsequent secondary forming, reduces adjustments needed during secondary forming due to errors in the initial forming, and further improves overall forming accuracy.

The primary forming mechanism can quickly twist the scattered parts of the wire harness into a regular shape, and the secondary forming mechanism further precisely shapes it. Compared with the traditional single forming method, this significantly improves the wire harness forming efficiency and can meet the needs of mass production. Attached Figure Description

[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0015] A dual-gun split-type terminal wire harness forming device, such as Figure 1-4The system includes a worktable 1, a primary forming mechanism, a secondary forming mechanism, and a fixing mechanism. The primary forming mechanism includes a first slide rail 2, a first slider 3, a support plate 4, a first pressure block 5, a first rod-mounted cylinder 6, a first rodless cylinder 7, a second pressure block 9, and a second slider 8. The support plate 4 is mounted on the worktable 1, the first slide rail 2 is mounted on the support plate 4, the first slider 3 is slidably mounted on the first slide rail 2, the first rod-mounted cylinder 6 is mounted on the support plate 4, the first pressure block 5 is mounted on the output end of the first rod-mounted cylinder 6, and the first pressure block 5 is connected to the first slider 3. The first rodless cylinder 7 is mounted on the worktable 1, the second slider 8 is mounted on the first rodless cylinder 7, and the second pressure block 9 is mounted on the top of the second slider 8. The first pressure block 5 is located directly above the second pressure block 9.

[0016] Using the above technical solution, the primary forming mechanism achieves the twisting and forming of the spread-out part of the wire harness through orderly mechanical movement. When the wire harness to be processed is placed on the second pressure block 9 at the top of the second slider 8, the first rod cylinder 6 starts to work. As the piston rod of the first rod cylinder 6 extends, it drives the first pressure block 5 to move vertically downward along the first slide rail 2, accurately pressing the wire harness on the second pressure block 9. The clamping force of the first pressure block 5 and the second pressure block 9 is used to fix the position of the wire harness and prevent the wire harness from shifting in subsequent operations. Subsequently, the first rodless cylinder 7 is activated, and the second slider 8 drives the second pressure block 9 and the clamped wire harness to reciprocate horizontally. During this process, as the wire harness is clamped by the first pressure block 5 and the second pressure block 9, under the action of horizontal reciprocating motion, the loose parts of the wire harness will be gradually twisted into a regular wire harness shape due to the interaction of friction and extrusion, completing the initial forming operation. After the initial forming is completed, the first rod cylinder 6 retracts its piston rod, driving the first pressure block 5 to rise and reset, while the first rodless cylinder 7 moves the second slider 8 and the formed wire harness to a suitable position, waiting for the fixing mechanism to perform the next operation.

[0017] The secondary forming mechanism includes a base 10, a third cylinder 11, a lateral limiting block 12, a support frame 13, a fourth cylinder 14, and a vertical pressing block 15. The base 10 is set on the worktable 1, the third cylinder 11 is symmetrically set on the worktable 1, the lateral limiting blocks 12 are all set on the third cylinder 11, and the lateral limiting blocks 12 are located on both sides of the base 10. The support frame 13 is set on the worktable 1 near the base 10, the fourth cylinder 14 is set on the support frame 13, and the vertical pressing block 15 is set on the output end of the fourth cylinder 14.

[0018] Using the above technical solutions, the secondary forming mechanism is mainly used to precisely shape the wire harness to ensure that it meets the final size and shape requirements. The fixing mechanism transfers the initially formed wire harness to the base 10, which serves as the supporting foundation for the secondary forming, providing a stable support plane for the wire harness. Then, the third cylinder 11 starts to operate. When the piston rod of the third cylinder 11 extends, it pushes the lateral limiting block 12 to move along the guide rail 19 towards the base 10, limiting and fixing the wire harness from both sides, precisely constraining the horizontal position of the wire harness and preventing lateral displacement during subsequent forming. As the piston rod of the fourth cylinder 14 extends, the vertical pressure block 15 moves vertically downward under the guidance of the guiding mechanism, gradually approaching and applying vertical pressure to the wire harness located on the base 10. The vertical pressure block 15 and the lateral limiting block 12 work together to squeeze the wire harness from multiple directions, further shaping the wire harness under pressure and completing the secondary forming process. After forming, the fourth cylinder 14 retracts its piston rod, driving the vertical pressure block 15 to rise and reset. The third cylinder 11 also retracts its piston rod, driving the lateral limiting block 12 to reset, making it convenient for the operator to remove the formed wire harness. The fixing mechanism includes a second rodless cylinder 16, a third slider 17, and a gripper 18. The second rodless cylinder 16 is mounted on the worktable 1, the third slider 17 is mounted on the second rodless cylinder 16, and the gripper 18 is mounted on the top of the third slider 17.

[0019] When the wire harness after the first forming needs to be transferred to the secondary forming mechanism, the second rodless cylinder 16 set on the worktable 1 is activated. The second rodless cylinder 16 drives the third slider 17 installed on it to move horizontally on the worktable 1. The gripper 18 installed on the top of the third slider 17 moves to the position of the wire harness that has been formed in the primary forming mechanism. The gripper 18 is existing technology and will not be described in detail here.

[0020] The base 10 has guide rails 19 on both the left and right sides, and the lateral limiting block 12 is slidably connected to the guide rails 19. When the third cylinder 11 is working, the extension and retraction of the piston rod is converted into the linear sliding of the lateral limiting block 12 along the guide rail 19, ensuring the smooth movement of the lateral limiting block 12.

[0021] Both the first pressure block 5 and the second pressure block 9 are rubber pads. The elasticity of the rubber pads allows them to fit tightly against the surface of the wire harness, preventing damage to the fragile outer sheath or internal conductors of the wire harness due to rigid compression while applying pressure. In addition, the surface of the rubber pad has a large frictional force. When the second pressure block 9 moves the wire harness horizontally back and forth under the drive of the first rodless cylinder 7, the frictional force between the rubber pad and the wire harness can effectively transmit the motion force, ensuring that the wire harness does not slip during twisting, thereby ensuring the smooth progress of the initial forming operation and improving the quality and efficiency of wire harness forming.

[0022] The support frame 13 is equipped with a guide mechanism, and the vertical pressure block 15 is connected to the guide mechanism. The guide mechanism provides vertical guidance for the vertical pressure block 15, making the wire harness more stable during the secondary forming process.
