Description
A pre-bending device for high-strength wire Technical Field
[0001] This utility model relates to the field of wire pre-bending technology, and in particular to a pre-bending device for high-strength wire. Background Technology
[0002] High-strength wire plays an indispensable role in many fields of modern industry due to its outstanding strength and toughness. In the construction industry, high-strength wire is widely used in the prestressed systems of large bridges and high-rise buildings. By applying prestress to the wire, the load-bearing capacity and crack resistance of the structure can be effectively improved, ensuring the safety and stability of the building during long-term use. In the machinery manufacturing industry, high-strength wire is often used to manufacture various springs, wire ropes, and other key components. These components require precise shapes and mechanical properties to meet the operational requirements of machinery under complex working conditions. In the automotive manufacturing industry, high-strength wire is widely used in components such as car seat adjustment mechanisms, engine valve springs, and suspension systems, directly affecting the comfort, power performance, and handling safety of the vehicle. With the continuous advancement of industrial technology, increasingly higher requirements are being placed on the processing precision and forming quality of high-strength wire. Many applications not only require the wire to have high strength but also require it to be bent and formed into specific shapes and angles to meet complex design and assembly needs. For example, in the aerospace field, some precision components require high-strength wires that need to be precisely pre-bent to specific angles to achieve perfect fit with other components and ensure the high-performance operation of the entire aerospace system. This need for precise control of the wire pre-bending angle has become an important driving force for the development of pre-bending technology.
[0003] Traditional pre-bending methods lack flexibility. Once the mold is determined, the achievable pre-bending angle is essentially fixed, making it difficult to quickly adapt to the diverse pre-bending angle requirements of different products. If the pre-bending angle needs to be changed, it is often necessary to remake the mold, which not only consumes a lot of time and money but also seriously affects production efficiency. Therefore, a pre-bending device for high-strength wire is proposed. Summary of the Invention
[0004] (a) Technical problems to be solved
[0005] The purpose of this invention is to provide a pre-bending device for high-strength wire, thereby solving the problem of poor flexibility in traditional pre-bending methods described in the background art. Once the mold is determined, the achievable pre-bending angle is basically fixed, making it difficult to quickly adapt to the diverse pre-bending angle requirements of different products. If the pre-bending angle needs to be changed, it is often necessary to remake the mold, which not only consumes a lot of time and money but also seriously affects production efficiency.

[0014] (III) Beneficial Effects
[0015] This utility model provides a pre-bending device for high-strength wire, which has the following beneficial effects:
[0016] 1. The high-strength wire pre-bending device, through the setting of the moving mechanism, allows for adjustment of the wire pre-bending degree during use. The hydraulic rod on the surface of the upright plate is activated, driving the telescopic rod at its end to move. This, in turn, pushes the pre-bending mold connected to one side of the telescopic rod within the positioning block at the bottom, thereby adjusting the gap between the pre-bending mold and the two mold plates. This achieves the effect of adjusting the wire pre-bending degree, improving the flexibility of the equipment during use.
[0017] 2. The high-strength wire pre-bending device, through the setting of a height adjustment mechanism, allows for height adjustment for operators of different heights. The top drive motor can be activated, causing the positive and negative lead screws at the end to rotate. This causes relative movement between the two threaded blocks connected to the threads on the surface of the lead screws, which in turn drives the rotating rod connected to the top of the threaded blocks to adjust the height of the placement plate at the top of the rotating rod. This achieves the effect of adjusting the device height, facilitating operation for personnel of different heights and providing convenience for operators. Attached Figure Description

[0025] The height adjustment mechanism 2 includes two fixed joints 201 fixedly connected to the bottom of the placement plate 1. A rotating rod 202 is rotatably connected to the surface of the fixed joint 201. A threaded block 203 is rotatably connected to the bottom of the rotating rod 202. A positive and negative screw 204 is threadedly connected inside the threaded block 203. A drive motor 205 is fixedly connected to one side of the positive and negative screw 204.
[0026] The moving mechanism 5 includes two telescopic rods 501 fixedly connected to one side of the pre-bending mold 4. A support plate 502 is fixedly connected to the middle of the surface of the telescopic rods 501, and a hydraulic rod 503 is fixedly connected to the surface of the support plate 502.
[0027] A vertical plate 6 is fixedly connected to one side of the hydraulic rod 503, and a placement plate 1 is fixedly connected to the bottom of the vertical plate 6. The placement plate 1 serves to support the vertical plate 6.
[0028] Two mold plates 7 are installed on one edge of the surface of the placement plate 1. The surface of the mold plate 7 is provided with positioning grooves that are compatible with the wire. The mold plate 7 serves as a pre-bending tool.
[0029] Two support blocks 8 are fixedly connected to the edges on both sides of the surface of the placement plate 1. The surface of the support blocks 8 is equipped with transmission wheels 9, which serve to transport the wire.
[0030] A transmission rod 10 is fixedly connected to the bottom of the transmission wheel 9, and a servo motor 11 is fixedly connected to the bottom of the transmission rod 10. The servo motor 11 drives the transmission wheel 9 to rotate.

[0033] In this invention, the working steps of the device are as follows:
[0034] First step: When using the wire, if it is necessary to adjust the degree of wire pre-bending, start the hydraulic rod 503 on the surface of the upright plate 6. The hydraulic rod 503 drives the telescopic rod 501 at the end to move, thereby pushing the pre-bending mold 4 connected to one side of the telescopic rod 501 to move inside the positioning block 3 at the bottom, so as to adjust the gap between the pre-bending mold 4 and the two mold plates 7.
