Description

Technical Field

[0001] The utility model relates to the technical field of wire bending, in particular to a tool for bending a whole bundle of wires. Background Art

[0002] One end of the wire harness in the electrical control cabinet is connected to the busbar or partially connected to the neutral bar. In actual operation, in order to facilitate wiring, the wire harness needs to be bent. In essence, the wire harness is bent into a U-shaped structure. Currently, the bending is done by the operator's hands. Most electrical control cabinets use copper wires with larger diameters, and the wire harness formed by a combination of multiple copper wires will increase the difficulty of bending, and the desired effect is often not achieved after bending. Therefore, multiple bending is required to achieve the desired effect. Utility Model Content

[0003] The utility model provides a tool for bending a whole bundle of wires, which solves the deficiencies of the above-mentioned prior art and the problem that the wire bundle is inconvenient to bend, and has strong practicality.

[0004] In order to achieve the purpose of this utility model, the following technologies are proposed:

[0005] A tool for bending a whole bundle of wires includes a U-shaped plate, an inner plate is provided in the arc section of the U-shaped plate, a rotating plate is rotatably provided on the inner plate, and a bending wheel is provided at the outer end of the rotating plate. When the whole bundle of wires is bent, the provided U-shaped plate plays a supporting role in the U-shaped bending. When the rotatable rotating plate rotates, it can act on the wire bundle through the bending wheel, thereby bending the wire bundle into a U-shaped structure. In addition, this bending method can avoid damage to the wire bundle.

[0006] Furthermore, in order to limit the position of the wire harness, an arc-shaped plate is formed on the U-shaped plate.

[0007] Furthermore, in order to facilitate the bending operation, a rotating handle is provided at the outer end of the rotating plate.

[0008] Furthermore, in order to avoid limiting the position of the wire, an arc-shaped annular groove is formed on the outer periphery of the bending wheel.

[0009] Furthermore, in order to limit one end of the wire harness so that the wire harness can be bent quickly, a plurality of spring pins are provided on one of the vertical sections of the U-shaped plate, and the outer end of the spring pin is sleeved with a movable sleeve plate, the inner side of the movable sleeve plate is provided with an inner top vertical plate, the inner end of the inner top vertical plate is provided with an arc clamping plate, and the inner end of the spring pin is sleeved with a spring, which is located on the inner side of the movable sleeve plate, and outer convex plates are respectively provided on both sides of the inner top vertical plate. The inner end of the outer convex plate is provided on the U-shaped plate, and the outer end of the outer convex plate is rotatably provided with a rotating column, and an inner top screw rod is screwed on the rotating column, and the inner end of the inner top screw rod acts on the inner top vertical plate.

[0010] Furthermore, in order to guide the movement of the arc clamp, a pair of guide holes are opened on the outer convex plate, and a limit screw is passed through the guide hole. The inner end of the limit screw is provided with an L-shaped connecting arm, and the inner end of the L-shaped connecting arm is provided on both sides of the inner top vertical plate.

[0011] Furthermore, in order to facilitate the rotation operation of the inner push screw, the inner end of the inner push screw is formed into a hemispherical structure.

[0012] The advantages of the above technical solution are:

[0013] The utility model facilitates the U-shaped bending operation of the wire bundle, thereby ensuring the bending effect of the wire bundle and reducing the difficulty of the U-shaped bending. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention will be described in further detail below with reference to the accompanying drawings.

[0015] Figure 1 A three-dimensional structural diagram of one embodiment is shown.

[0016] Figure 2 An enlarged view of point A is shown. DETAILED DESCRIPTION

[0017] like Figure 1~Figure 2 As shown, a tool for bending a whole bundle of wires includes a U-shaped plate 1, an arc-shaped plate 10 is formed on the U-shaped plate 1, an inner plate 11 is provided in the arc section of the U-shaped plate 1, a rotating plate 2 is rotatably provided on the inner plate 11, a rotating shaft is provided on the rotating plate, the rotating shaft passes through the inner plate, and the length of the rotating shaft is relatively long, a rotating handle 20 is provided at the outer end of the rotating plate 2, a bending wheel 21 is provided at the outer end of the rotating plate 2, and an arc-shaped annular groove is formed on the outer periphery of the bending wheel 21.

[0018] A plurality of spring pins 3 are provided on one of the vertical sections of the U-shaped plate 1. The outer end of the spring pin 3 is sleeved with a movable sleeve plate 31. The inner side of the movable sleeve plate 31 is provided with an inner top vertical plate 32. The inner end of the inner top vertical plate 32 is provided with an arc clamping plate 33. The inner end of the spring pin 3 is sleeved with a spring 30. The spring 30 is located on the inner side of the movable sleeve plate 31. The two sides of the inner top vertical plate 32 are respectively provided with an outer convex plate 36. The inner end of the outer convex plate 36 is provided on the U-shaped plate 1. The outer end of the outer convex plate 36 is rotatably provided with a rotating column 38. An inner top screw rod 39 is screwed on the rotating column 38. The inner end of the inner top screw rod 39 is a hemispherical structure. The inner end of the inner top screw rod 39 acts on the inner top vertical plate 32. A pair of guide holes 37 are formed on the outer convex plate 36 , and a limit screw 35 is passed through the guide hole 37 . The inner end of the limit screw 35 is provided with an L-shaped connecting arm 34 , and the inner end of the L-shaped connecting arm 34 is provided on both sides of the inner top vertical plate 32 .

[0019] When operating this embodiment, the operator first passes the bundled wire bundle through the arc clamping plate 33 and the arc plate 10, and also needs to pass the wire bundle through the arc-shaped annular groove of the bending wheel 21.

[0020] Then the operator rotates the inner top screw 39 so that the inner end of the inner top screw 39 acts on the L-shaped connecting arm 34, thereby causing the arc clamp 33 to act on the wire bundle and complete the positioning operation on one end of the wire bundle. If the limiting effect of one end of the wire bundle is poor, the inner top screw 39 can be rotated to ensure the clamping and positioning effect of the arc clamp 33 on the wire bundle.

[0021] The operator then pre-bends the wire bundle. The operator then rotates the rotating plate 2 by turning the handle 20. As the rotating plate 2 rotates, the bending wheel 21 acts on the wire bundle, ultimately bending the wire bundle into a U-shape. The bending wheel 21 is then pulled outward, releasing the positioning of the wire bundle, and the wire bundle is finally removed.

[0022] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Therefore, if such modifications and variations fall within the scope of the claims and their equivalents, the present invention is intended to include such modifications and variations.
