Description

Technical Field

[0001] This utility model relates to the field of electrical control cabinet processing technology, and in particular to a multi-wire bending tool. Background Technology

[0002] When wiring electrical control cabinets, in order to facilitate the storage of wires and ensure the neatness of the cable layout, it is often necessary to fold the wire bundles in half, that is, bend the wire bundles into a U-shape. However, if the bundle contains a large number of wires, it is inconvenient to bend them. Folding each wire individually not only affects the neatness of the wires after bending, making it inconvenient to bundle them, but also reduces efficiency. Utility Model Content

[0003] This utility model provides a multi-wire bending tool to solve the shortcomings of the prior art, which is inconvenient for folding the entire wire bundle in half, and has strong practicality.

[0004] In order to achieve the purpose of this utility model, the following technology is proposed to be adopted:

[0005] A multi-wire bending tool includes an inner liner. One end of the inner liner has a semi-circular arc structure. A semi-circular arc plate is fitted onto the semi-circular arc end of the inner liner. The semi-circular arc plate is movably mounted on the inner liner. When bending the wire bundle, the inner liner supports the wire bundle, while the semi-circular arc plate acts on the wire bundle, causing the wire bundle to bend inward around the inner liner. This facilitates the overall bending of the wire bundle and improves the overall folding effect and efficiency of the wire bundle.

[0006] Furthermore, the inner liner has a groove with a pair of slotted holes at the bottom. A pair of movable screws are inserted into the slotted holes. The outer ends of the movable screws are connected to a movable plate via threads. A semi-circular arc plate is welded to the movable plate. One end of the inner liner is fixed to an end plate by screws. A movable lead screw is rotatably mounted on the end plate. One end of the movable lead screw has an end cap. A limit ring is connected to the movable lead screw via a pin. The limit ring is located on the upper side of the end plate. A threaded sleeve is connected to the movable lead screw via threads. A connecting plate is welded to the threaded sleeve. The connecting plate is welded to the movable plate. When the movable lead screw rotates, it can drive the semi-circular arc plate to move. During the movement, it can bend the wire harness into a U-shaped structure. This structural design is mainly for facilitating folding operations.

[0007] Furthermore, the two ends of the semi-circular arc plate are bent outwards to form quarter-circle arc plates. The arc plates can prevent damage to the insulation layer of the wire harness when folding the wire harness.

[0008] Furthermore, an end plate is welded to the movable plate, and an adjusting screw is rotatably mounted on the end plate. A rotating head is located at the upper end of the adjusting screw. A constraint ring is connected to the adjusting screw via a pin, and the constraint ring is located on the lower wall of the end plate. An adjusting push plate is threaded onto the adjusting screw, and an adjusting back plate is welded to the inner end of the adjusting push plate. A concave groove is formed on the adjusting back plate, and the end plate passes through the concave groove. A pair of guide holes are formed on the adjusting back plate, with the length direction of the guide holes parallel to the axial direction of the adjusting screw. A constraint screw passes through the guide holes, and the inner end of the constraint screw is threaded onto the movable plate. An opening is provided on the upper part, with the outer end of the opening extending upward at an angle. A moving rod passes through the opening, and a pair of transverse holes are provided on the moving plate. The moving rod passes through the transverse holes, and a pressure roller is provided at one end of the moving rod. The pressure roller is located on both sides of the inner liner. The outer end of the moving rod is connected to a limit nut by a thread. The limit nut is located on the outer side of the adjusting back plate. Through the provided pressure roller, when it moves with the moving plate, it can bend the wire harness into a V-shaped structure, thereby facilitating the bending of the U-shaped structure. At the same time, the spacing can be adjusted according to the amount of wire harness to expand the applicable range.

[0009] Furthermore, the outer periphery of the inner liner is provided with an embedded groove to limit and constrain the wire harness, so as to prevent the wire harness from detaching from the contact with the inner liner.

[0010] Furthermore, the inner wall of the semi-circular plate is equipped with a rubber pad to prevent damage to the insulation layer of the wires when folded.

[0011] The advantages of the above technical solution are:

[0012] This invention enables the folding of wire harnesses, reducing the difficulty of folding and improving the efficiency and effectiveness of folding. Attached Figure Description

[0013] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will provide a more detailed description of this utility model in conjunction with the accompanying drawings.

[0015] Figure 2 A three-dimensional structure of one embodiment is shown. Figure 2 . Detailed Implementation

[0016] like Figures 1-2As shown, a multi-wire bending tool includes an inner liner 1. An embedded groove 11 is provided on the outer periphery of the inner liner 1. One end of the inner liner 1 has a semi-circular arc structure. A semi-circular arc plate 27 is fitted on the semi-circular arc structure end of the inner liner 1. Both ends of the semi-circular arc plate 27 are bent outward to form quarter-circular arc plates 28. The semi-circular arc plate 27 is movably mounted on the inner liner 1. A rubber pad 42 is provided on the inner wall of the semi-circular arc plate 27.

[0017] The inner liner 1 has a groove 10, and a pair of strip holes 12 are formed at the bottom of the groove 10. A pair of movable screws 26 are inserted into the strip holes 12. The outer ends of the movable screws 26 are connected to a movable plate 25 by threads. A semi-circular plate 27 is welded to the movable plate 25. One end of the inner liner 1 is fixed to an end plate 2 by screws. A movable lead screw 20 is rotatably provided on the end plate 2. One end of the movable lead screw 20 is provided with an end cap 21. A limit ring 22 is connected to the movable lead screw 20 by a pin. The limit ring 22 is located on the upper side of the end plate 2. A threaded sleeve ring 23 is connected to the movable lead screw 20 by threads. A connecting plate 24 is welded to the threaded sleeve ring 23. The connecting plate 24 is welded to the movable plate 25.

[0018] An end plate 36 is welded onto the movable plate 25. An adjusting screw 34 is rotatably mounted on the end plate 36. A rotating head 35 is located at the upper end of the adjusting screw 34. A constraint ring is connected to the adjusting screw 34 via a pin. The constraint ring is located on the lower wall of the end plate 36. An adjusting push plate 33 is threaded onto the adjusting screw 34. An adjusting back plate 38 is welded to the inner end of the adjusting push plate 33. A concave groove 41 is formed on the adjusting back plate 38. The end plate 36 passes through the concave groove 41. A pair of guide holes 40 are formed on the adjusting back plate 38. The length direction of the guide holes 40 is parallel to the axial direction of the adjusting screw 34. A constraint screw 37 is inserted into the guide hole 40. The inner end of the constraint screw 37 is threaded to the moving plate 25. An opening oblique hole 39 is provided on the adjusting back plate 38. The outer end of the opening oblique hole 39 extends upward. A moving rod 30 is inserted into the opening oblique hole 39. A pair of transverse holes 29 are provided on the moving plate 25. The moving rod 30 is inserted into the transverse holes 29. One end of the moving rod 30 is provided with a pressure roller 32. The pressure roller 32 is located on both sides of the inner liner 1. The outer end of the moving rod 30 is threaded to a limit nut 31. The limit nut 31 is located on the outer side of the adjusting back plate 38.

[0019] In this embodiment, when performing the folding operation of the wire harness, the operator adjusts the distance between the two pressure rollers 32 according to the number of wires contained in the wire harness. During adjustment, the operator rotates the adjusting screw 34 by rotating the rotating head 35. When the adjusting screw 34 rotates, it drives the adjusting push plate 33 on it, so that the adjusting push plate 33 drives the adjusting back plate 38 to move relative to the moving plate 25. When the adjusting back plate 38 moves, it opens the oblique hole 39 and acts on the moving rod 30, thereby causing the moving rod 30 to move outward or inward along the transverse hole 29. The movement of the moving rod 30 will change the distance between the pressure rollers 32. The operator then places the wire harness between the arc-shaped end of the inner liner 1 and the pressure roller 32. Thus, when the pressure roller 32 moves, the inner liner 1 acts as a fulcrum, acting on the wire harness to bend it inwards around the inner liner 1. Furthermore, the movement of the pressure roller 32 causes the semi-circular arc plate 27 to act on the bend of the wire harness, further enhancing the U-shaped folding effect. While the pressure roller 32 moves, the operator rotates the moving screw 20 via the end cap 21. This rotation of the moving screw 20 drives the moving plate 25, its semi-circular arc plate 27, and the pressure roller 32 to act on the wire harness, thereby completing the U-shaped folding operation.
