[0029] As Figures 1-3 shown, the present invention provides a ninety-degree arc bending tooling. Some specific embodiments are described below. In one specific embodiment of the ninety-degree arc bending tooling, it includes a bracket 1 for fixing a conductor and a side plate 5 hinged to the bracket 1 through a hinge shaft 4. Among them, the conductor can include material conductors such as copper conductors and superconducting tapes. This bending tooling can bend copper conductors and can also bend superconducting tapes. In this embodiment, a copper conductor is taken as an example for illustration:

[0030] The bracket 1 includes a base 101 and a support plate 102 formed on the base 101. A fixing channel 103 is provided on the base 101. The number of support plates 102 is two, which are respectively formed on both sides of the fixing channel 103. The copper conductor passes through the area formed between the two support plates 102 and reaches the fixing channel 103. The fixing channel 103 can pass through the copper conductor. When the conductor passes through the fixing channel 103, it is fixed by the fixing channel 103, achieving the purpose of fixing one end while bending the other end of the conductor. An arc surface 104 that bends downward is formed at the end of the base 101. The upper end of the arc surface 104 is flush with the bottom surface of the fixing channel 103. When the copper conductor reaches the arc surface 104 after passing through the fixing channel 103, the copper conductor can be bent downward closely attached to the arc surface 104 to complete the bending of the copper conductor.

[0031] To provide the bending force for the copper conductor, a rotating shaft 2 is rotatably mounted above the two support plates 102 through a third fixing member 10. The rotating shaft 2 is located above the fixing channel 103 and can rotate. A lead screw 3 is threadedly connected to the rotating shaft 2 (the threads on the lead screw 3 are omitted in Figure 1 , 2 ). The lead screw 3 is driven to rotate by an external force and can move forward or backward on the rotating shaft 2. The number of side plates 5 is two, which are respectively hinged to both sides of the bracket 1 through a hinge shaft 4. The shapes of the two side plates 5 are both L-shaped. A roller 6 and a limiting shaft 7 are rotatably mounted on the side plates 5. More specifically, the roller 6 is rotatably mounted between the two side plates 5 through a first fixing member 8. The limiting shaft 7 is rotatably mounted between the two side plates 5 through a second fixing member 9. The roller 6 is located at one end close to the arc surface 104, and the limiting shaft 7 is located between the roller 6 and the rotating shaft 2. The axis of the hinge shaft 4 is located at the center of the circle of the arc surface 104. The roller 6 cooperates with the arc surface 104, and the distance between the roller 6 and the arc surface 104 can pass through the copper conductor. During use, after the copper conductor passes through the fixing channel 103, a section to be bent is passed through the space between the roller 6 and the arc surface 104. The end of the lead screw 3 is rotatably connected to the limiting shaft 7. The lead screw 3 can rotate on the limiting shaft 7 and push the limiting shaft 7 to move when moving. When the lead screw 3 rotates, it pushes the limiting shaft 7 to move away from the rotating shaft 2 side. The limiting shaft 7 thus drives the roller 6 to rotate around the arc surface 104, bending the copper conductor along the arc surface 104 to achieve bending. The radian of the arc surface 104 is 90 degrees, so the device of the present application can achieve a 90-degree circular arc bending.

[0032] The fixed channel 103 can be set in various ways. One of the setting ways disclosed in this application is that a placement surface 105 is formed on the base 101, and a fixed cover 106 is fixed on the placement surface 105 by bolts. The area enclosed by the fixed cover 106 and the placement surface 105 is the fixed channel 103, and the longitudinal cross-sectional shape of the fixed channel 103 is the same as that of the conductor, so as to ensure that the fixed channel 103 can fix the conductor and prevent the conductor from shaking when bent. In this embodiment, the copper conductor is a long strip with a square longitudinal cross-section. Correspondingly, the placement surface 105 is a plane and is flush with the upper end of the arc surface 104, and the longitudinal cross-section of the inner cavity of the fixed cover 106 is square. The copper conductor can pass through the inner cavity of the fixed cover 106 by closely adhering to the placement surface 105, so that the fixed cover 106 fixes the copper conductor and prevents one end of the copper conductor from tilting during bending.

[0033] To facilitate the screwing of the lead screw 3, a screwing block 301 is formed at the free end of the lead screw 3, and the lead screw can be screwed by an external tool such as a wrench, so as to push the roller 6 forward, which is relatively labor-saving.

[0034] After considering the specification and the disclosure here in practice, those skilled in the art will easily think of other implementation schemes of the present invention. This application aims to cover any variations, uses or adaptive changes of the present invention, and these variations, uses or adaptive changes follow the general principles of the present invention and include the common general knowledge or conventional technical means in the technical field not disclosed in the present invention. The specification and embodiments are only regarded as exemplary, and the true scope and spirit of the present invention are pointed out by the following claims.

[0035] It should be understood that the present invention is not limited to the exact structure already described and shown in the drawings, and various modifications and changes can be made without departing from its scope. The scope of the present invention is only limited by the appended claims.
