[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] See also Figure 1-3 , for winding Figure 3The utility model provides a technical solution: a special-shaped torsion spring winding jig, including a block-shaped main body 5, except that the bottom surface of the main body 5 is used to stably place the main body 5, the other sides of the main body 5 can be provided with bending modules B1, bending modules D2, bending modules C3, spring winding modules A4, and bending and winding modules of various specifications and shapes can be provided on each side of the main body 5 as needed, so that a set of jigs can realize at least five parts of bending and winding operations, with a high degree of integration. The jig is used in winding Figure 3 In the embodiment of the special-shaped torsion spring shown in the figure, the bending module B1, the bending module D2, the bending module C3, and the spring winding module A4 are respectively used for Figure 3 Bending and forming the B, D and C positions of the special-shaped torsion spring, and winding and forming the spring at position A of the special-shaped torsion spring;

[0018] The raw material for winding special-shaped torsion springs is metal strips. Figure 3 When the special-shaped torsion spring is wound, the first step is to fix the metal strip in the clamping block 41, and clamp it by rotating the handle A42, and insert the mandrel into the mandrel hole A43 set on both sides of the clamping block 41, and then use the cylindrical tool to wind two springs with a fixed distance, and then turn the direction and wind two springs to complete. Figure 3 The four springs at the special-shaped torsion spring A are wound, one of the core shaft holes A43 is set on a movable adjustment block 45, and the adjustment block 45 is slidably installed in the adjustment slot 44. The relative position of the adjustment block 45 and the adjustment slot 44 is adjusted and fixed by the adjustment screw 46 on the main body 1 to achieve the purpose of adjusting the distance between the two springs;

[0019] In the second step, the semi-finished product with four springs wound is placed on the round table 11 of the bending module B1, and the handle B15 is adjusted to drive the clamping block 14 to clamp the middle of the semi-finished product. The limit column B13 forms the fulcrum of the bending at B, and the limit rod is inserted into the limit hole B12 to position the spring.

[0020] The third step is to insert the mandrel into the mandrel hole C32, then put the spring of the special-shaped torsion spring on the mandrel, insert the limit rod into the limit hole 33 to form a fulcrum, and cooperate with the limit column C31 to bend the C in the special-shaped torsion spring;

[0021] The fourth step is to place the semi-finished product in the placement groove 12, align the spring part with the mandrel hole D22, insert the mandrel into the mandrel hole D22 to play a positioning role, and then insert the limit rod into the limit hole D23 to form a bending fulcrum to achieve precise bending of the special-shaped torsion spring D;
