Description

Technical Field

[0001] This utility model relates to the field of wire processing technology, specifically to a wire bending fixture. Background Technology

[0002] There is a type of wire, such as Figure 1 As shown, a wire needs to be divided into two connected wires, namely wire one and wire two. This involves stripping off the outer insulating layer in the middle to expose the conductive layer as the connection end. Then, another wire, known as wire three, is vertically connected to the connection end (i.e., the exposed conductive layer) behind it using a soldering process. After soldering, wire one needs to be bent forward 90°, and wire three needs to be bent upward 90°, to the right 90°, and downward 90° from the connection end position.

[0003] In existing technologies, wire bending is typically done manually by operators, requiring tools such as pliers and clamps. This process is cumbersome, time-consuming, labor-intensive, and inefficient. Furthermore, manual operation relies on personal experience, making it difficult to guarantee bending accuracy and often requiring multiple corrections, resulting in poor product consistency. This is especially true for complex wires requiring multiple bends, such as bending wire one forward 90° and bending wire three sequentially upward, rightward, and downward 90°, where manual operation is more prone to errors, impacting product quality and production efficiency. Therefore, a wire bending fixture has been designed to address these issues.

[0004] It should be noted that the above introduction to the technical background is only for the purpose of providing a clear and complete explanation of the technical solutions of this utility model and facilitating understanding by those skilled in the art. It should not be assumed that these technical solutions are known to those skilled in the art simply because they have been described in the background section of this utility model. Utility Model Content

[0005] To overcome the shortcomings of the prior art, the purpose of this utility model is to provide a wire bending fixture.

[0006] To achieve the above and other related objectives, the technical solution provided by this utility model is: a wire bending fixture for bending wire, wherein the wire includes wire body one, wire body two and wire body three, wire body three is connected to wire body one and wire body two by soldering and the connection point forms a T-shaped solder sleeve, wire body one is provided with a first bending area, and wire body three is provided with a second bending area, a third bending area and a fourth bending area in sequence; The fixture includes a work platform, on which a control console is mounted; the work platform also includes: A positioning block, wherein a T-shaped positioning groove is provided on the positioning block, and the positioning groove is adapted to the solder sleeve; The first bending unit is located to the left of the positioning block. The first bending unit includes a first clamp and a first pusher. The first clamp is correspondingly set to the first bending area to be bent on the first line body. The first pusher is located on one side of the first clamp. The movement direction of the first pusher is correspondingly set to the bending direction of the first line body. The second bending unit is located behind the positioning block. The second bending unit includes a second clamp, a second pusher, and a third pusher. The second clamp is correspondingly positioned to the second and third bending areas on the line body to be bent. The second pusher is located on one side of the second clamp. The movement directions of the second pusher and the third pusher are respectively set to correspond to the first bending direction and the second bending direction of the line body three; The third bending unit is located to the right of the second bending unit. The third bending unit includes a third clamp and a fourth pusher. The third clamp is corresponding to the fourth bending area to be bent on the third line body. The fourth pusher is located above the third clamp, and the movement direction of the fourth pusher is corresponding to the third bending direction of the third line body.

[0007] This solution achieves accurate positioning and orderly bending of wires through the cooperation of positioning blocks and three bending units, improving bending efficiency and accuracy, and ensuring product consistency.

[0008] Furthermore, the first, second, third, and fourth pushing components have identical structures, each including a connecting shaft that is driven by a driving component, and a pushing body is mounted on the connecting shaft. The pushing body is a rotating body with a smooth curved surface that is concave in the middle on its outer contour surface. In this design, the pushing components have a uniform structure, which facilitates manufacturing and maintenance. The concave curved surface of the pushing body is adapted to the line body, ensuring stable and reliable pushing and preventing the line body from slipping. Specifically, the pushing body is shaped like a waisted cylinder (the shape of the waisted portion is adapted to the line body). The waisted design better accommodates the line body, increases the contact area, improves pushing stability, and avoids bending deviations.

[0009] Furthermore, the pusher body and the connecting shaft are rotatably connected via bearings. In this design, the bearing connection ensures smooth rotation of the pusher body, reduces friction, extends service life, and ensures a stable bending process.

[0010] Furthermore, the second clamp includes a clamp body, on which a first pressing block for abutting the second bending area after forming and a second pressing block for abutting the third bending area after forming are provided; the clamp body is also provided with a wire-clamping block for clamping the wire, the wire-clamping block being located above the first pressing block. In this solution, the second clamp fixes the wire through the pressing blocks and the wire-clamping block, ensuring accurate positioning of the wire during bending and improving bending accuracy.

[0011] Furthermore, a support plate is provided between the second clamp and the third clamp, with one end of the support plate fixed to the second clamp. In this design, the support plate provides additional support to prevent deformation or movement of the line during bending, ensuring bending quality.

[0012] Furthermore, both the right side of the first clamp and the front side of the second clamp are provided with a flip-up wire-stopping block, and the lower end of the wire-stopping block has a contour groove adapted to the wire body. In this design, the wire-stopping block blocks the wire body during bending to prevent deviation, and the contour groove improves positioning accuracy and ensures bending consistency.

[0013] Furthermore, the upper end of the third clamp is provided with a wire-holding groove, and a flip-up wire-pressing device is provided above the wire-holding groove. In this solution, the wire-pressing device can press down the wire, ensuring the stability of the wire during bending, preventing loosening, and improving bending accuracy.

[0014] Furthermore, the upper end of the wire-blocking block is connected to an elbow clamp, and the wire-pressing device is an elbow clamp. In this solution, the elbow clamp can provide quick clamping and release, is easy to operate, improves production efficiency, and reduces setup time.

[0015] Furthermore, the control console is located at the front right corner of the work platform. The control console is equipped with a start button, a first control button for controlling the first pushing component, a second control button for controlling the second pushing component, a third control button for controlling the third pushing component, and a fourth control button for controlling the fourth pushing component. In this design, the control console has a reasonable layout, is intuitive to operate, and facilitates centralized control of the bending process by the user, thus improving operational convenience.

[0016] Furthermore, a safety cover is provided above the first bending unit. In this design, the safety cover protects the operator, prevents accidental injury during the bending process, and improves the safety of the working environment.

[0017] Due to the application of the above technical solution, the beneficial effects of this utility model compared with the prior art are as follows: This utility model's wire bending fixture achieves automation and standardization of the wire bending process through integrated positioning blocks and the coordinated operation of three bending units. The fixture uses a T-shaped positioning groove to precisely fix the tin sleeve connection end of the wire, ensuring accurate initial positioning. The first bending unit bends the wire forward by 90°, the second bending unit bends it upward and then to the right by 90° sequentially, and the third bending unit completes the final downward bend of 90°. Each pushing component adopts a unique waist-shaped pushing body design, combined with bearing rotation connection, making the bending process smooth and stable, effectively preventing wire slippage. Furthermore, the fixture is equipped with a wire stop block, wire pressing device, and support plate, further enhancing bending stability. Centralized control at the control console ensures easy operation. Compared to traditional manual bending, this fixture significantly improves production efficiency, reliably guarantees bending accuracy and product consistency, and is suitable for mass production environments, solving the long-standing technical problems of low bending efficiency and poor accuracy in the industry.
