[0005] As a preferred technical solution of the present invention, the driving member is a disc that rotates and is eccentrically mounted on the base plate, and a handle is provided on the side of the disc.

[0006] As an optimal technical solution of the present invention, a reset groove is provided in the middle of the movable mold base, and a reset spring is placed in the reset groove. One end of the reset spring presses against the inner wall of the reset groove, and the other end presses against the top block provided at the bottom of the guide block.

[0007] As a preferred technical solution of the present invention, the bottoms of the end forming mold and the middle forming mold are both loading joints, and the tops are the mold bodies.

[0008] As an optimal technical solution of the present invention, the end forming mold is used in conjunction with a winding auxiliary component. The main body of the winding auxiliary component is a cylinder, and a positioning hole and a winding limit pin are provided at the end of the cylinder, and a rotary handle is provided at the other end.

[0009] Compared with the prior art, the beneficial effect of the present invention is that the high-precision manual forming jig set for special-shaped leaf springs can not only be used to process the special-shaped leaf springs in this embodiment, but can also be applied to other leaf spring processing and forming operations that require winding or press forming. It only requires redesigning a special pressing or winding mold and loading it, thereby achieving the purpose of low-cost and high-precision production of special-shaped leaf springs.

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

[0017] See also Figure 1-4The utility model provides a technical solution: a special leaf spring high-precision manual forming jig group, including a base plate 1, a fixed die seat 2, a guide block 5 and a driving member 4 are installed on the base plate 1 from left to right, the driving member 4 is a disc that is rotatable and eccentrically installed on the base plate 1, and a handle 6 is provided on the side of the disc. The handle 6 drives the disc to rotate, and the eccentrically arranged disc drives the movable die seat 3 to move left, so that the two parts of the end forming die 11 or the middle forming die 12 clamp or press the leaf spring raw material to be processed, and the movable die seat 3 is slidably provided in the guide groove of the guide block 5. A reset groove 7 is provided in the middle, and a reset spring 8 is placed in the reset groove 7. One end of the reset spring 8 presses on the inner wall of the reset groove 7, and the other end presses on the top block 9 provided at the bottom of the guide block 5. After the force on the handle 6 is withdrawn, the reset spring 8 drives the movable die seat 3 to move right, releasing the clamped workpiece.
