Description

Technical Field

[0001] The utility model relates to the technical field of wire harness processing, in particular to a wire softening device for wire harness processing. Background Technique

[0002] The wire softening device in wire harness processing is a device specifically used for processing hardened wires. During wire production or processing, due to low temperature and low internal temperature in the factory, different processing methods are generally adopted according to needs during wire production and processing. For example, when stripping the wire, traditional stripping generally directly cuts and strips the wire. However, some wires are relatively hard and are not easy to cut open during cutting and stripping.

[0003] Currently, during wire harness processing, individual wires need to be processed, including wire stripping. To facilitate wire stripping, the wire is usually softened to reduce the hardness of the electrical outer skin. The common method is usually to pass the wire through the inside of the warm air box and heat the wire through the warm air box to soften the wire.

[0004] To ensure that the warm air box effectively heats the wire and achieves softening, one method is to slow down the transmission speed of the wire inside the warm air box, thereby prolonging its residence time in the warm air box. However, this method may reduce the efficiency of wire processing. Another method is to keep the wire transmission speed unchanged and increase the length of the warm air box to extend the heating time of the wire inside the warm air box. However, increasing the length of the warm air box will occupy more factory space. Content of the Utility Model

[0036] Please refer to Figure 1-2 , an electric wire softening device for wire harness processing in this embodiment, which is used to effectively soften the electric wire without reducing the transmission speed of the electric wire and without increasing the length of the warm air box 1, ensuring the efficiency of wire softening.

[0037] Specifically, it includes a warm air box 1, a cover plate 2, at least four guide wheels 3 and a heating mechanism 4; both the left and right sides of the warm air box 1 protrude outward from the inside to form a protruding part, and the warm air box 1 is provided with a heating cavity along the X-axis direction so that one end of the electric wire can extend from one side of the warm air box to the opposite side, and the cover plate 2 is hinged to the front side of the inner wall of the warm air box 1 through a hinge shaft;

[0038] During actual use, by opening the cover plate 2, the electric wire is inserted from the left side of the warm air box 1, and the electric wire passes through the heating mechanism 4 and then exits from the right side of the warm air box 1. In actual setting, a viewing window can also be provided inside the cover plate 2 to facilitate observing the use state inside the warm air box 1.

[0039] In addition, when the warm air box 1 in this embodiment is actually set, its length in the XZ-axis direction does not exceed 1.5 m and 0.8 m respectively.

[0040] Specifically, in order to increase the heating time of the electric wire inside the warm air box 1, at least four of the guide wheels 3 in this embodiment are symmetrically installed in groups of two at the top and bottom of the inner wall of the warm air box 1, so that the electric wire passes through at least four guide wheels 3 in sequence and is distributed in a Z-shape inside the warm air box 1; the heating mechanism 4 is arranged on the warm air box 1 to soften the electric wire.

[0041] During actual use, one end of the electric wire is inserted into the warm air box 1 from the left side of the warm air box 1, and one end of the electric wire passes through the inside of the two lower guide wheels 3 in sequence, and after passing through the rightmost guide wheel 3 at the lower side, one end of the electric wire passes through the inside of the two upper guide wheels 3 in sequence, so that the electric wire located inside the warm air box 1 is distributed in a Z-shape, thereby increasing the length of the electric wire inside the warm air box 1, so as to extend the heating time of the electric wire to be softened.

[0042] Please refer to Figure 3 and 4, in order to heat and soften the electric wires inside the warm air box 1, the heating mechanism 4 in this embodiment includes a heat supply component, at least one connecting pipe 401, at least three air cylinders 402 and a plurality of air outlets 403; the heat supply component is arranged outside the warm air box 1, at least three air cylinders 402 are communicated with the heat supply component through at least one connecting pipe 401, at least three air cylinders 402 are arranged at intervals up and down, and at least three air cylinders 402 are all sleeved outside the electric wire, and a plurality of air outlets 403 are respectively communicated inside at least three air cylinders 402.

[0043] During the actual use process, heat is generated by the heat supply component, and the connecting pipe 401 conveys the generated heat to the inside of the three air cylinders 402, and the hot air is evenly blown to the outer surface of the electric wire through the air outlets 403 inside the air cylinders 402, so as to heat and soften the electric wire passing through the warm air box 1, while ensuring the uniformity of heating, avoiding problems of local overheating or uneven temperature, and increasing the efficiency of heating and softening the electric wire.

[0044] It should be noted that, in order to ensure the stable installation of the air cylinders 402, the upper and lower air cylinders 402 in this embodiment are respectively installed at the top and bottom of the inner wall of the warm air box 1, and the middle air cylinder 402 is installed between the opposite sides of the upper and lower air cylinders 402 through a connecting plate 404, and the three air cylinders 402 and the guide wheels 3 are all located on the same ZX plane.

[0045] Furthermore, in order to adapt to the shape of the distribution of the electric wire inside the warm air box 1, preferably, the upper and lower air cylinders 402 in this embodiment are arranged in parallel, and the middle air cylinder 402 is arranged in a left-high and right-low inclined manner, that is, the upper and lower air cylinders 402 respectively heat the upper and lower parts of the electric wire inside the warm air box 1, while the middle air cylinder 402 heats the inclined part of the electric wire, and the three parts of the electric wire are respectively located on the axial lines of the three air cylinders 402.

[0046] Even further, in order to ensure that the hot air can be effectively conveyed to the inside of the air cylinder 402 and output from the inside of the air outlet 403, in this embodiment, a sandwich layer 405 is opened on the inner wall of the air cylinder 402, the connecting pipe 401 is communicated with the sandwich layer 405, and a plurality of air outlets 403 are distributed in an annular array on the inner peripheral wall of the air cylinder 402 and are communicated with the sandwich layer 405.

[0047] During the actual setting, the hot air inside the heat supply component is conveyed to the inside of the sandwich layer 405 through the connecting pipe 401 and output through the air outlets 403 inside the sandwich layer 405 to heat the electric wire inside it.

[0048] In addition, for the convenience of maintaining the interior of the interlayer 405, a plug 406 is threadedly connected inside the interlayer 405. During actual use, the plug 406 can be rotated to remove it from the inner wall of the interlayer 405, thereby maintaining the inner wall of the interlayer 405 to prevent the air outlet nozzle 403 from being blocked.

[0049] Specifically, to achieve the heating effect, the heating component in this embodiment includes a fan 407, a box body 408, and an electric heating element 409. The fan 407 and the box body 408 are both assembled on the warm air box 1, and the output end of the fan 407 is communicated with the box body 408. The electric heating element 409 is installed on the inner wall of the box body 408 to generate heat inside the box body 408. At least one connecting pipe 401 is communicated with the box body 408 to convey the generated hot air into the interiors of at least three air cylinders 402.

[0050] During actual use, the air inside the box body 408 is heated by the electric heating element 409, and the heat generated is carried and conveyed into the connecting pipe 401 by the operation of the fan 407. The hot air is respectively conveyed into the interiors of the three air cylinders 402 through the connecting pipe 401 and is output from the air outlet nozzle 403 inside the air cylinder 402 to heat and soften the wires inside.

[0051] Please refer to Figure 5 , to ensure that the wires inside the warm air box 1 are in a taut state during transmission and to ensure that the transmitted wires are always located on the axial line of the air cylinder 402, this embodiment further includes two clamping components 5, which are respectively installed on the left and right sides of the warm air box 1.

[0052] During actual installation, by installing the clamping components 5 on the left and right sides of the warm air box 1 and clamping the wires, the wires are kept in a taut state during transmission, ensuring that the wires are always located on the axial line of the air cylinder 402, making the wires heated evenly during the heating process, avoiding the problem of uneven heat distribution caused by position deviation, and improving the heating effect and safety.

[0053] Specifically, to clamp the two ends of the wire, the clamping component 5 in this embodiment includes four clamping arms 501, two clamping rollers 502, and two tension springs 503. Every two of the four clamping arms 501 are in a group and are respectively hinged on the upper and lower sides of the left end face of the warm air box 1 through a hinge shaft. The two clamping rollers 502 are respectively rotatably connected to the two groups of clamping arms 501, and the two clamping rollers 502 are in mutual contact. The two groups of clamping arms 501 are connected by at least two tension springs 503, and the included angles between the two groups of clamping arms 501 and the warm air box 1 are both less than ninety degrees.

[0054] During actual use, the wire is passed through between the two clamping rollers 502. Due to the elastic force of the two tension springs 503, the two clamping arms 501 are always provided with a force for rotating towards each other, so that the two clamping rollers 502 are closely attached to the outer side of the wire. Moreover, through the adaptive design of the tension springs 503, effective clamping effect can still be maintained when the wire diameter changes slightly, improving the stability and reliability during wire transmission.

[0055] Preferably, in order to adapt to wires of different diameters and achieve the clamping effect on wires of different diameters, in this embodiment, at least two annular grooves are formed on the outer side of the clamping roller 502, and the widths of at least two annular grooves in the Y-axis direction increase from back to front.

[0056] During actual setting, the setting of multiple annular grooves of different sizes enables the clamping roller 502 to flexibly adapt to wires of different diameters. For thicker wires, the wider groove part can be used for clamping; for thinner wires, the narrower groove part can be used to ensure the clamping effect and stability.

[0057] Finally, several points should be noted: First, in the description of the present application, it should be noted that unless otherwise specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense, which can be mechanical connection or electrical connection, and can also be the communication inside two components.
