Description

Technical Field

[0001] The invention belongs to the field of wires, and in particular relates to an electric wire bending tool. Background Art

[0002] The wires in the prior art refer to wires that transmit electrical energy. They are divided into bare wires, electromagnetic wires and insulated wires. Bare wires have no insulation layer, including copper and aluminum flat wires, overhead stranded wires and various profiles. They are mainly used for outdoor overhead and indoor busbars and switch boxes. Electromagnetic wires are insulated wires that generate a magnetic field or induce current in a magnetic field after being energized. They are mainly used for windings of motors and transformers and other related electromagnetic equipment. The conductor is mainly copper wire, which should have a thin insulation layer and good electrical and mechanical properties, as well as heat resistance, moisture resistance, solvent resistance and other properties. Different insulation materials can be used to obtain different characteristics.

[0003] The Chinese patent with publication number CN113351793A discloses a large-diameter insulated wire bending machine, which aims to provide a large-diameter insulated wire bending machine that is not only easy and quick to operate, but also can ensure the bending effect of large-diameter insulated wires and bend large-diameter insulated wires into a specific angle. It includes a bracket; a fixed roller group, the fixed roller group includes two left and right fixed rollers arranged side by side on the bracket, and the two fixed rollers are used to block the insulated wire to be bent; a wire bending mechanism, the wire bending mechanism includes a moving roller and a jack fixed on the bracket, and the jack is used to drive the moving roller to move, so as to bend the insulated wire between the two fixed rollers.

[0004] The jack in the above application is heavy and is usually fixed on a work surface for use. It is not suitable for use in aerial operations. However, wires are used very frequently in aerial operations and are usually bent in time according to on-site needs for better use. When encountering larger wires, it consumes a lot of physical strength, and the bending effect does not meet the use requirements, resulting in a significant reduction in work efficiency.

DETAILED DESCRIPTION

[0043] The present invention will now be described in further detail with reference to the accompanying drawings.

[0044] See also Figure 1-6As shown, in this embodiment, an electric wire bending tool is provided, including: a vertical bracket 1, a horizontal bracket 101 is fixed in the middle of the opposite sides of the vertical bracket 1, the vertical bracket 1 and the horizontal bracket 101 are combined into a cross structure, a slide rail 2 is opened in the middle of the front side of the vertical bracket 1, one end of the slide rail 2 is rotatably matched with a screw rod 5, the circumferential side thread of the screw rod 5 is matched with a sliding bracket 3, one end of the screw rod 5 passes through one end of the vertical bracket 1 and is equipped with an electric wrench 4, and the sliding bracket 3 is slidably matched in the slide rail 2; by arranging the sliding bracket 3 and the screw rod 5 in the vertical bracket 1, and using the electric wrench 4 to drive the screw rod 5 and the sliding bracket 3 to move, the use of manpower is effectively reduced.

[0045] A plurality of main wire-clamping posts 6 are fixed on the front side of the sliding bracket 3, and auxiliary wire-clamping posts 7 are fixed on the front sides of the opposite ends of the horizontal bracket 101. The main wire-clamping posts 6 and auxiliary wire-clamping posts 7 are respectively arranged on the front sides of the sliding bracket 3 and the horizontal bracket 101, and the wires are clamped between the main wire-clamping posts 6 and the auxiliary wire-clamping posts 7, and the movement of the main wire-clamping posts 6 is driven by the sliding bracket 3, so as to realize the bending function of the wires, greatly reduce the physical consumption, and can quickly bend wires of different specifications, effectively improving its working efficiency. The lower sides of the opposite ends of the horizontal bracket 101 are elastically slidably matched with telescopic plates 8, and the front sides of the telescopic plates 8 are rotatably matched with positioning wheels 15 corresponding to the auxiliary wire-clamping posts 7. A connecting plate 9 is fixed between the bottom of the rear sides of the two telescopic plates 8, and the connecting plate 9 is slidably matched with the rear part of the vertical bracket 1. By setting the telescopic plate 8 under the cross bracket 101 and the positioning wheel 15 on the front side of the telescopic plate 8, the positions of the telescopic plate 8 and the positioning wheel 15 can be adjusted according to the wires of different thicknesses, so that the positioning wheel 15 can position and clamp the two ends of the wire bending part, effectively reducing the occurrence of the wire slipping during the bending process, thereby better bending the wire and further improving the working efficiency of the bending tool.

[0046] The application of one aspect of this embodiment is: when using an electric bending tool, the part of the wire that needs to be bent is placed on the upper side of one of the main clamping posts 6, and then the two ends of the wire bending part are placed on the lower sides of the two auxiliary clamping posts 7. At this time, the connecting plate 9 is manually loosened, so that the two telescopic plates 8 elastically rebound and drive the two positioning wheels 15 to move synchronously to the side close to the two auxiliary clamping posts 7, thereby achieving the clamping and positioning of the two ends of the wire, and then the electric wrench 4 is started, and the output end of the electric wrench 4 drives the screw rod 5 to rotate, so that the screw rod 5 and the sliding bracket 3 are threadedly matched, thereby driving the sliding bracket 3 to slide and match in the slide rail 2 and move toward the end extending out of the slide rail 2. At this time, the main clamping post 6 moves synchronously to drive the wire to bend. During this bending process, since the two ends of the wire will be pulled synchronously, the two positioning wheels 15 rotate synchronously, thereby better achieving the bending work of the wire. It should be noted that all electrical equipment involved in this application can be powered by batteries or external power supplies.

The L-shaped plate 12 and the telescopic plate 8 are slidably matched in the groove 11, and a spring 13 is fixed between the top of the groove 11 and the inner side of the L-shaped plate 12. When the wire needs to be positioned, the elastic rebound force of the spring 13 drives the L-shaped plate 12 to retract into the groove 11, and at the same time, the L-shaped plate 12 drives the telescopic plate 8 to retract into the groove 11 synchronously, and then the telescopic plate 8 drives the positioning wheel 15 to move to the side close to the auxiliary clamping column 7, so as to realize the positioning and clamping of the wire between the positioning wheel 15 and the auxiliary clamping column 7.

[0050] like Figure 4-5 As shown, a fixed shaft 14 is fixed to the front side of the telescopic plate 8 of this embodiment, and one end of the fixed shaft 14 is rotatably matched with a positioning wheel 15. When the wire is in the bending process, both ends of the wire will move accordingly, and the wire will drive the positioning wheel 15 to rotate synchronously during the movement.

[0051] like Figure 1-2 As shown, a slide groove 10 is provided at the rear side of the vertical bracket 1 of this embodiment, and the connecting plate 9 slides up and down in the slide groove 10, and the slide groove 10 is located at the rear side of the two tracks 16, and the slide groove 10 is located below the horizontal bracket 101. When it is not necessary to position and clamp the wire, the connecting plate 9 is manually pulled downward so that the connecting plate 9 slides in the slide groove 10, and then the connecting plate 9 drives the two telescopic plates 8 to move downward synchronously and extend out of the groove 11, and at this time, the positioning wheel 15 moves to the side away from the auxiliary clamping column 7, canceling the positioning and clamping relationship of the wire.

[0052] The present invention is not limited to the above-mentioned embodiments. Anyone should be aware that any structural changes made under the enlightenment of the present invention, and any technical solutions that are the same or similar to the present invention, fall within the protection scope of the present invention.
