Description

Technical Field

[0001] This utility model relates to the technical field of wire bending, and in particular to a multi-wire bending device. Background Technology

[0002] Currently, large and medium-sized transformers are core equipment in power transmission and distribution systems, and coils are key components for power conversion. After the coil winding process is completed, the conductors at the input and output ends need to be bent at an arc. The core purpose is to adapt to the compact installation space inside the transformer, thereby meeting the docking requirements with the terminals and lead structures, and ensuring the neat arrangement of the conductors. However, the bending of the conductors at the input and output ends of the coil still generally adopts the traditional manual bending method. Specifically, operators need to use simple tools such as wrenches and hammers, relying on personal experience and physical strength to apply external force to the conductors, thereby gradually bending the conductors to the target shape. The whole process is time-consuming and labor-intensive. When bending multiple thick conductors, the combined stiffness of multiple thick conductors is large and the bending resistance is strong. Manual operation consumes even more manpower, resulting in extremely high labor intensity and low work efficiency. Utility Model Content

[0003] To address the above shortcomings, this utility model proposes a multi-wire bending device. It utilizes two adjustable mounting plates to accommodate wire groups with different numbers of wires, and uses the cooperation of a pressure plate and a waist-shaped hole to bend the wire groups, thereby reducing manual labor and shortening the operation time of the bending process.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A multi-wire bending device includes: a fixing plate, two mounting plates movably disposed on the fixing plate in a horizontal direction, each mounting plate having an oblong hole in a vertical direction, two limiting rods detachably disposed between the two mounting plates for supporting multiple wires, a pressure plate movably disposed between the two mounting plates, the pressure plate having an arcuate surface that mates with the oblong hole, and a driving mechanism connected to the pressure plate for driving the arcuate surface to move along the oblong hole, so that the arcuate surface bends the multiple wires downward.

[0005] Furthermore, the upper end of the mounting plate includes two L-shaped blocks arranged opposite each other, and a stepped hole with the small end facing upward is defined between the two L-shaped blocks. The stepped hole is located above the waist-shaped hole. The fixing plate is slidably engaged with the large end of the stepped hole, and the lateral part of the L-shaped block abuts against the upper end surface of the fixing plate.

[0006] Furthermore, the driving mechanism is a hydraulic cylinder mounted on the fixed plate, the telescopic rod of the hydraulic cylinder is connected to a mounting block, and the pressure plate is connected to the lower part of the mounting block.

[0007] Furthermore, the mounting plate is provided with two limiting strips opposite to each other, the waist-shaped hole is located between the two limiting strips, and a guide block is slidably provided between the two limiting strips. The guide block is provided with a guide hole through which the pressure plate can move.

[0008] Furthermore, there are two pressure plates, and the guide block is horizontally provided with a guide rod. The two pressure plates are symmetrically arranged with respect to the axis of the guide rod, and the guide block slides in cooperation with the pressure plate and the guide rod.

[0009] Furthermore, the mounting plate is provided with a first threaded hole, and the limiting strip is provided with a second threaded hole, the first threaded hole and the second threaded hole are connected by bolts.

[0010] Furthermore, each of the mounting plates has two mounting holes spaced horizontally at its lower part, the waist-shaped hole is located between the two mounting holes, and the limiting rod is movably inserted through the two opposite mounting holes along the moving direction of the mounting plate.

[0011] Furthermore, the mounting hole is a circular hole, the limiting rod is a circular rod-shaped structure that mates with the circular hole, and the line connecting the centers of the two mounting holes intersects perpendicularly with the axis of the waist-shaped hole.

[0012] Compared with existing technologies, this utility model has at least the following beneficial effects: 1.

[0013] 2. This utility model utilizes the cooperation of two limiting strips and guide blocks. The guide blocks are provided with guide holes through which the pressure plate can move, thereby regulating the translational movement of the pressure plate in the vertical direction, and making it easier for the pressure plate to press down and bend the wire assembly.

[0021] See Figures 1 to 3A multi-wire bending device includes: a fixing plate 100, two mounting plates 110 movably disposed on the fixing plate 100 in the horizontal direction, each mounting plate 110 having an oblong hole 111 in the vertical direction, two limiting rods 120 detachably disposed between the two mounting plates 110 for supporting multiple wires, and a pressure plate 130 movably disposed between the two mounting plates 110, the pressure plate 130 having an arcuate surface that mates with the oblong hole 111, the pressure plate 130 being connected to a driving mechanism for driving the arcuate surface to move along the oblong hole 111, so that the arcuate surface bends multiple wires downward.

[0022] In the multi-wire bending device with the above structure, the distance between the two mounting plates 110 is first adjusted according to the width of the wire group with different numbers of wires. Then, the wire group is placed above the two limiting rods 120. Finally, the drive mechanism drives the pressure plate 130 downward, thereby bending the wire group by utilizing the cooperation between the arc-shaped surface and the oblong hole 111. Through the above structure, the adjustable mounting plate 110 accommodates wire groups with different numbers of wires, and the cooperation between the pressure plate 130 and the oblong hole 111 bends the wire group, thereby reducing manual labor and shortening the bending process time.

[0023] See Figures 1 to 3 Furthermore, the upper end of the mounting plate 110 includes two L-shaped blocks arranged opposite each other, with a stepped hole 112 defined between the two L-shaped blocks, the smaller end of which faces upward. The stepped hole 112 is located above the waist-shaped hole 111. The fixing plate 100 slides with the larger end of the stepped hole 112, and the lateral portion of the L-shaped block abuts against the upper end surface of the fixing plate 100. Specifically, the two L-shaped blocks are integrally formed on the upper part of the mounting plate 110, and the two L-shaped blocks define the stepped hole 112 that slides with the fixing plate 100. This allows the lateral portion of the L-shaped block to form a planar contact with the upper end surface of the fixing plate 100, which is beneficial for regulating the translation of the mounting plate 110 relative to the fixing plate 100, and also for installing the mounting plate 110 from the side of the fixing plate 100. In some embodiments, the mounting plate 110 is provided with a first through hole, and the fixing plate 100 is provided with a plurality of second through holes at intervals along its length, so that a pin or a locking rod can be inserted into the corresponding second through hole and the first through hole, which is beneficial to quickly fix the position of the mounting plate 110 after it has been moved.

[0024] See Figures 1 to 3Furthermore, the driving mechanism is a hydraulic cylinder 140 mounted on the fixed plate 100. The telescopic rod of the hydraulic cylinder 140 is connected to the mounting block 150, and the pressure plate 130 is connected to the lower part of the mounting block 150. Specifically, the telescopic rod of the hydraulic cylinder 140 drives the mounting block 150 to move vertically, thereby facilitating the downward pressing or upward reset of the pressure plate 130. This provides a continuous and stable driving force through the hydraulic cylinder 140, replacing manual labor and effectively overcoming the bending resistance of multiple thick wires, significantly reducing manpower consumption. Simultaneously, the hydraulic drive responds quickly, enabling rapid synchronous bending of multiple wires, significantly shortening the operation time of a single process. It is understood that the pressure plate 130 and the mounting block 150 are integrally formed or welded into a single structure, and the driving mechanism can also be pneumatically driven, which will not be detailed here.

[0025] See Figures 1 to 3 Furthermore, the mounting plate 110 is provided with two limiting strips 160 opposite each other, and the oblong hole 111 is located between the two limiting strips 160. A guide block 170 is slidably arranged between the two limiting strips 160, and the guide block 170 is provided with a guide hole 171 through which the pressure plate 130 can move. Specifically, the limiting strips 160 and the guide block 170 are in planar sliding contact, which helps to prevent the pressure plate 130 from rotating in the horizontal direction, so as to regulate the translational movement of the pressure plate 130 in the vertical direction, thereby facilitating the downward bending of the wire assembly by the pressure plate 130. The cooperation between the pressure plate 130 and the guide hole 171 is beneficial to the simultaneous movement of the guide block 170 when the pressure plate 130 moves, and also to the displacement of the guide block 170 when the position of the mounting plate 110 is adjusted. In some implementations, the sidewall of the limiting strip 160 is provided with a groove along its height direction, one end of which passes through the lower end of the limiting strip 160. The sidewall of the guide block 170 is provided with a protrusion that is inserted upward into the groove, thereby facilitating the guide block 170 to always slide between the two limiting strips 160.

[0026] See Figures 1 to 3 Furthermore, two pressure plates 130 are provided, and a guide rod 172 is horizontally provided on the guide block 170. The two pressure plates 130 are symmetrically arranged with respect to the axis of the guide rod 172. The guide block 170 slides in cooperation with the pressure plate 130 and the guide rod 172, thereby using the upper pressure plate 130 and the guide rod 172 to further enhance the guiding effect on the lower pressure plate 130.

[0027] See Figures 1 to 3 Furthermore, the mounting plate 110 is provided with a first threaded hole, and the limiting strip 160 is provided with a second threaded hole 161. The first threaded hole and the second threaded hole 161 are connected by bolts, thereby simplifying the installation or removal of the limiting strip 160 from the mounting plate 110.

[0028] See Figures 1 to 3Furthermore, each mounting plate 110 has two horizontally spaced mounting holes 113 at its lower part, with a waist-shaped hole 111 located between the two mounting holes 113. A limiting rod 120 is movably inserted through the two opposing mounting holes 113 along the moving direction of the mounting plate 110. Specifically, when crimping the wire assembly, the two limiting rods 120 are inserted into the corresponding two mounting holes 113, and then the distance between the two mounting plates 110 is adjusted so that the wire assembly can be placed on the upper end of the two limiting rods 120. After the wire assembly is bent, the two limiting rods 120 are removed, facilitating the removal of the wire assembly from the lower end of the two mounting plates 110, thus simplifying the bending and disassembly time of the wire assembly.

[0029] See Figures 1 to 3 Furthermore, the mounting hole 113 is a circular hole, and the limiting rod 120 is a round rod-shaped structure that matches the circular hole. The line connecting the centers of the two mounting holes 113 intersects perpendicularly with the axis of the waist-shaped hole 111, which facilitates the wire assembly to bend away from the two limiting rods 120 under the action of the pressure plate 130, thereby quickly completing the bending of the wire assembly.

[0030] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0031] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
