Description

A bending device for folded cables Technical Field

[0001] This utility model relates to the field of electrical control cabinet processing technology, and in particular to a bending device for folded cables. Background Technology

[0002] When manufacturing electrical control cabinets, the wires of controller switches located at different heights are often bent into a folded structure for connection. This folded structure is advantageous because the connection ports of the controller switches at different heights are not aligned. It facilitates the connection operation between the controller switches. However, currently, for smaller diameter wires, bending is done with pliers. This bending method is usually performed during the wire connection process, which is difficult to operate and makes it hard to control the bending point. Furthermore, improper operation by the operator can damage the wire insulation. In addition, bending is also inconvenient when the wire diameter is large. Summary of the Invention

[0003] This utility model provides a bending device for folded cables to overcome the shortcomings of the prior art and solve the problem of inconvenience in bending wires, thus having strong practicality.

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

[0005] A folding cable bending device includes a base plate with a rectangular structure. A pair of clamping plates are provided on the base plate, with an angle between the length direction of the clamping plates and the length direction of the base plate. A pair of limiting blocks are provided on the base plate, with one side of the limiting blocks being an inclined surface. The limiting blocks are located at both ends of the clamping plates, and the length direction of the inclined surface is parallel to the length direction of the base plate. An L-shaped rotating seat is mounted on the base plate, and a hinge shaft is welded to the upper end of the L-shaped rotating seat. A rotating plate is rotatably mounted on the hinge shaft, and a lower extension rod is provided at each end of the rotating plate.

[0006] Furthermore, a locking nut is threadedly connected to the upper end of the hinge shaft, and the locking nut is located on the upper side of the rotating plate.

[0007] Furthermore, the rotating plate has waist-shaped holes at both ends, and an inner rod passes through the waist-shaped holes. The upper end of the inner rod is connected to a limit nut by a thread. The limit nut is located on the upper side of the rotating plate, and the lower end abuts against the upper side of the rotating plate. The lower end of the inner rod is located on the lower extension rod.

[0008] Furthermore, two pairs of movable holes are provided on the substrate. The length direction of the movable holes is perpendicular to the length direction of the card plate. Connecting screws are inserted into the movable holes. The lower end of each pair of connecting screws is connected to a limiting lower plate by a thread. The upper wall of the limiting lower plate abuts against the lower wall of the substrate. A wing plate is formed on the outer side of the card plate. The wing plate is located at the upper end of each pair of connecting screws.

[0009] Furthermore, two pairs of elongated holes are provided on the substrate. The length direction of the elongated holes is parallel to the length direction of the card plate. Locking screws are inserted into the elongated holes. The upper end of each pair of locking screws is located on the limiting block, and the lower end of each pair of locking screws is connected to a lower top plate by a thread. The upper wall of the lower top plate abuts against the lower wall of the substrate.

[0010] Furthermore, a rotating concave rod is welded onto the rotating plate.

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

[0012] This invention uses a pair of adjustable-spacing clamps to hold wires of different diameters. In addition, by setting the clamps to an inclined state, the wires can be tilted before bending, which facilitates the bending operation of the folded structure.

[0013] This invention uses a limiting block as a fulcrum during bending, allowing the wire to bend with the limiting block as the fulcrum. At the same time, the inclined surface ensures the bending effect of the wire.

[0014] This utility model uses a rotating plate. When the plate rotates, the lower extension rod on it acts on the wire, causing the wire to bend with the limiting block as the fulcrum. Attached Figure Description

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will provide a further detailed description of this utility model in conjunction with the accompanying drawings.

[0018] Figure 3 shows a three-dimensional structural diagram of one embodiment. Detailed Implementation

[0019] As shown in Figures 1-3, a folded cable bending device includes a base plate 1, which has a rectangular structure. A pair of clamping plates 22 are provided on the base plate 1, with an angle between the length direction of the clamping plates 22 and the length direction of the base plate 1. A pair of limiting blocks 31 are provided on the base plate 1, with one side of the limiting block 31 being an inclined surface. The limiting blocks 31 are located at both ends of the clamping plates 22, and the length direction of the inclined surface is parallel to the length direction of the base plate 1. An L-shaped rotating seat 40 is installed on the base plate 1, and a hinge shaft 41 is welded to the upper end of the L-shaped rotating seat 40. A rotating plate 43 is rotatably provided on the hinge shaft 41, and a rotating concave rod 48 is welded to the rotating plate 43. A lower extension rod 47 is provided at each end of the rotating plate 43, and a rotating sleeve is rotatably provided on the lower extension rod 47 to avoid damage to the wire when it is in operation. A locking nut 42 is threadedly connected to the upper end of the hinge shaft 41, and the locking nut 42 is located on the upper side of the rotating plate 43.

[0020] In this embodiment, a straight wire is placed between the clamping plates 22. After placement, the wire is moved as needed so that the limiting block 31 is located at the bending point of the wire. Then, the operator rotates the rotating plate 43. When the rotating plate 43 rotates, the lower extension rod 43 on it will act on the outside of the wire and make the wire bend into a folded structure.

[0021] In some embodiments, the rotating plate 43 has oblong holes 44 at both ends, and an inner rod 45 passes through the oblong holes 44. The upper end of the inner rod 45 is connected to a limit nut by a thread. The limit nut is located on the upper side of the rotating plate 43, and the lower end abuts against the upper side of the rotating plate 43. The lower end of the inner rod 45 is located on the lower extension rod 47. When adjusting the position of the lower extension rod according to the bending position of the wire, the operator first loosens the limit nut and then adjusts the position of the lower extension rod. This operation can further expand the scope of application.

[0022] In some embodiments, two pairs of movable holes 11 are provided on the substrate 1. The length direction of the movable holes 11 is perpendicular to the length direction of the clamping plate 22. A connecting screw 2 is inserted into the movable hole 11. The lower end of each pair of connecting screws 2 is connected to a limiting lower plate 20 by a thread. The upper wall of the limiting lower plate 20 abuts against the lower wall of the substrate 1. A wing plate 21 is formed on the outer side of the clamping plate 22. The wing plate 21 is located at the upper end of each pair of connecting screws 2. When adjusting the position of the clamping plate 22 to clamp and limit wires of different diameters, the operator first loosens the connecting screws 2 and then adjusts the spacing between the clamping plates 22. During the adjustment process, the clamping plates 22 are moved as far as possible by ensuring that they move the same distance. After moving to the appropriate position, the operator rotates the connecting screws 2 to make the upper wall of the limiting lower plate 20 abut against the lower wall of the substrate 1.

[0023] In some embodiments, the substrate 1 has two pairs of elongated holes 10, the length direction of which is parallel to the length direction of the clamping plate 22. Locking screws 3 are inserted into the elongated holes 10. The upper end of each pair of locking screws 3 is mounted on a limiting block 31, and the lower end of each pair of locking screws 3 is threadedly connected to a lower top plate 30. The upper wall of the lower top plate 30 abuts against the lower wall of the substrate 1. To facilitate adjustment of the distance or position of the bending point of the wire, the limiting block 31 is moved and positioned within the elongated hole 10. When adjustment is required, the operator first loosens the locking screws 3, then adjusts the position of the limiting block 31, and then tightens it again using the locking screws 3.

[0024] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations of this utility model fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
