Description

Technical Field

[0001] This utility model relates to the field of wire straightening technology, and in particular to a nickel alloy wire straightening device. Background Technology

[0002] In modern industrial production and engineering construction, wire materials are widely used, especially metal wires such as nickel alloy wire. During production, transportation, or storage, nickel alloy wire often undergoes bending and deformation due to various factors. This bending and deformation can adversely affect the performance of the nickel alloy wire and the operation of related equipment during subsequent use.

[0003] Currently, there are various methods for straightening nickel alloy wires on the market. One method involves creating a guide hole inside a guide cylinder, through which the bent nickel alloy wire is passed to straighten it. However, when the bending radius of the nickel alloy wire is large, the angle between the wire and the guide hole is also large. This results in a large angle between the wire inside and outside the guide hole. Consequently, when the wire inside the guide hole is moved vertically, the friction between the wire outside the hole and the guide cylinder is significant, greatly increasing the resistance encountered during wire movement and exacerbating wear. Utility Model Content

[0004] To address the problem that existing straightening devices lack a guiding mechanism for nickel alloy wires, which easily leads to wear, this invention provides a nickel alloy wire straightening device. By setting a conical guide cover to control the straightening angle of the nickel alloy wire, the included angle between the nickel alloy wire and the guide hole is reduced, thereby reducing the resistance during the movement of the nickel alloy wire and thus reducing wear.

[0005] This invention provides a nickel alloy wire straightening device, including a main support and a straightening bracket mounted on top of the main support. A straightening wheel is rotatably mounted on the straightening bracket, and a guide cylinder is fixedly mounted at the wire inlet of the straightening wheel. A guide hole for the nickel alloy wire to pass through is opened at the center of the guide cylinder. A conical guide cover is mounted outside the guide cylinder, with the diameter of the conical guide cover decreasing from bottom to top. The conical guide cover confines the nickel alloy wire within the cover, preventing excessive straightening angles from causing wear on the wire.

[0006] Furthermore, a rotational straightening assembly is provided on the outside of the guide cylinder for adjusting the angle of the conical guide cover. The conical guide cover can rotate and adjust its position along with the wire.

[0007] Furthermore, the rotational straightening assembly includes a sphere and an annular support. The sphere is fixedly mounted at the bottom of the guide cylinder, and the annular support is rotatably mounted outside the sphere. A conical guide cover is fixedly connected to the annular support. Through the clearance fit between the sphere and the annular support, rotational adjustment in any direction can be performed.

[0008] Furthermore, the conical guide cover is connected to the guide cylinder by several springs, which are arranged circumferentially around the guide cylinder with the guide wire hole as the center. A certain pulling force is applied to the conical guide cover by the springs. When the force on the conical guide cover is greater than that of the springs, the conical guide cover will rotate.

[0009] Furthermore, a connecting ring that can move along the axis of the guide cylinder is provided on the guide cylinder. One end of the spring is fixedly connected to the connecting ring, and the other end is fixedly connected to the conical cover. The tension of the spring can be adjusted by adjusting the position of the connecting ring on the guide cylinder.

[0010] Furthermore, the outer surface of the guide cylinder is provided with a threaded section, and the connecting ring has an internally threaded hole that matches the threaded section. The spring tension is adjusted and self-locking is achieved through the cooperation of the threaded section and the internally threaded hole, resulting in good stability.

[0011] Furthermore, the conical cover includes a straightening ring and several support bars. The upper ends of the support bars are fixedly connected to an annular bracket, and several springs are correspondingly connected to the support bars. The lower ends of the support bars are inclined away from the axis of the guide wire hole and connected to the straightening ring. The straightening ring is supported by the inclined support bars, and the nickel alloy wire is in direct contact with the straightening ring.

[0012] Furthermore, a connecting piece is provided at the lower end of the support bar, and a through hole is opened on the connecting piece. A screw is fixedly installed on the upper surface of the straightening ring, opposite to the through hole. The screw passes through the through hole and is connected to a nut. The cooperation of the screw and nut facilitates the replacement of the severely worn straightening ring.

[0013] The beneficial effects of this utility model are as follows:

[0014] This invention provides a nickel alloy wire straightening device. By setting a conical guide cover to control the straightening angle of the nickel alloy wire, the included angle between the nickel alloy wire and the guide hole is reduced, thereby reducing the resistance encountered by the nickel alloy wire during movement. This ensures the straightening of the wire while reducing the wear of the wire. Attached Figure Description

[0020] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0021] To reduce the angle between the nickel alloy wire and the guide hole, thereby minimizing wire wear, a nickel alloy wire straightening device is designed, such as... Figure 1 As shown, the system includes a main support 1 and a straightening support 11 mounted on top of the main support 1. A straightening wheel 3 is rotatably mounted on the straightening support 11, and a guide cylinder 4 is fixedly mounted at the wire inlet of the straightening wheel 3. When the nickel alloy wire passes through the guide hole 41 of the guide cylinder 4, the nickel alloy wire can be initially straightened through the vertically opened guide hole 41. After initial straightening, the nickel alloy wire passes around the straightening wheel 3 and is adjusted again by the straightening wheel 3. Then, the straightened nickel alloy wire is wound up by a subsequent winding device.

[0022] like Figure 2 As shown, the core of this technical solution lies in the fact that the guide cylinder 4 has a guide hole 41 at its center for the nickel alloy wire to pass through, and a conical guide cover 2 is provided on the outside of the guide cylinder 4, with the diameter of the conical guide cover 2 decreasing from bottom to top. When the nickel alloy wire enters the guide hole 41, the entry angle of the nickel alloy wire is controlled by the conical guide cover 2, which can reduce the included angle between the nickel alloy wire and the guide hole 41, reduce the resistance between the nickel alloy wire and the guide cylinder 4 when the nickel alloy wire moves, and make the straightening operation smoother.

[0023] When the force on the conical guide cover 2 is less than the deformation value, the conical guide cover 2 is fixedly connected to the outside of the guide cylinder 4 and cannot be moved. When the force on the conical guide cover 2 is greater than the deformation value, the conical guide cover 2 can be rotated under force. The angle between the conical guide cover 2 and the nickel alloy wire can be adjusted by the conical guide cover 2, reducing the pressure on the conical guide cover 2 when the nickel alloy wire moves, and reducing the damage to the conical guide cover 2 when the nickel alloy wire moves.

[0024] A rotating straightening assembly is provided on the outside of the guide cylinder 4 for adjusting the angle of the conical guide cover 2. Specifically, the rotating straightening assembly includes a sphere 5 and an annular support 6. The sphere 5 is fixedly mounted on the bottom of the guide cylinder 4, and the annular support 6 is rotatably mounted on the outside of the sphere 5. The conical guide cover 2 is fixedly connected to the annular support 6. The conical guide cover 2 is connected to the guide cylinder 4 by several springs 7, which are arranged circumferentially around the guide wire hole 41.

[0025] The sphere 5 and the annular bracket 6 are fitted with a clearance, allowing rotation in any direction. The angle of the conical guide cover 2 can be adjusted by rotating the annular bracket 6. To prevent the conical guide cover 2 from moving when the force it receives is less than its deformation value, multiple springs 7 arranged in a circular array around the center of the guide wire hole 41 are mounted on the periphery of the guide cylinder 4. The lower ends of the multiple springs 7 are all connected to the annular bracket 6. The deformation value of the conical guide cover 2 is the value of the force when the spring 7 deforms under force. When the force on the conical guide cover 2 is less than the deformation value of the spring 7, the conical guide cover 2 can be stably fixed on the outside of the guide cylinder 4. When the force on the conical guide cover 2 is greater than the deformation value of the spring 7, the conical guide cover 2 can rotate.

[0026] like Figure 3 As shown, in order to adjust the tension of the spring 7, a connecting ring 8 that can move along the axis of the guide cylinder 4 is provided on the guide cylinder 4. One end of the spring 7 is fixedly connected to the connecting ring 8, and the other end is fixedly connected to the conical cover. The tension of the spring 7 can be adjusted by adjusting the position of the connecting ring 8 on the guide cylinder 4.

[0027] To adjust the position of the connecting ring 8, a threaded section is provided on the outer surface of the guide cylinder 4, and the connecting ring 8 has an internal threaded hole that matches the threaded section. By rotating the connecting ring 8, it can be moved and adjusted along the threaded section of the guide cylinder 4, and it can self-lock after adjustment, providing good stability.

[0028] The conical cover includes a straightening ring 21 and several support bars 22. The upper ends of the support bars 22 are fixedly connected to the annular bracket 6, and several springs 7 are correspondingly connected to the support bars 22. The lower ends of the support bars 22 are inclined away from the axis of the guide hole 41 and connected to the straightening ring 21. During the process of guiding the nickel alloy wire, the straightening ring 21 is in direct contact with the nickel alloy wire. When the straightening ring 21 is subjected to significant wear, it can be replaced to reduce the number of replacement parts and lower costs.

[0029] Specifically, a connecting piece 23 is provided at the lower end of the support bar 22, and a through hole is opened on the connecting piece 23. A screw 24 opposite to the through hole is fixedly provided on the upper surface of the straightening ring 21. The screw 24 passes through the through hole and is connected to a nut 25. With the setting of the screw 24 and the nut 25, the straightening ring 21 can be fixed relatively stably while being detachable.

[0030] The above description is illustrative only and not restrictive of this utility model. Those skilled in the art will understand that many modifications, variations or equivalents can be made without departing from the spirit and scope defined by the appended claims, and all such modifications, variations or equivalents will fall within the protection scope of this utility model.
