[0015] Figure 1 This is a schematic diagram of the forming tooling for the round cap-type TO packaged component of this utility model;

[0016] Figure 2 This is a schematic diagram of the forming tooling structure for the round cap-type TO packaged component of this utility model. Detailed Implementation

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments:

[0018] like Figure 1 , Figure 2 The diagram shows a schematic of the forming fixture for a round-cap type TO packaged component according to this utility model. It adopts a separate structure design, including a base 1, a first lead positioning module 2, a second lead positioning module 3, a pressure block 4, and a positioning post 5. A square groove is provided on the surface of the base 1, and a circular groove is provided at the center of the square groove. The component body is placed in the groove of the base 1. The depth of the circular groove is 4.0–5.0 mm, which serves to fix the component and prevent relative displacement during the forming process.

[0019] The first leg positioning module 2 and the second leg positioning module 3 have a symmetrical structure. After they are installed into the square groove of the base 1, their inner surfaces will fit tightly together to form two rings, one inner and one outer. The diameter of the inner ring on the lower surface is 5.5-6.5 mm, and the diameter of the outer ring on the upper surface is 19-22 mm. The pressure block 4 has a cylindrical structure with a sloping lower surface and a hollow center.

[0020] To ensure that the pressure block does not shift during the pressing process, a positioning post 5 is designed. The positioning post 5 can be inserted into the center hole of the pressure block 4 and gently press down against the center of the bottom surface of the component body to ensure that the pressure block 4 is pressed in an accurate position.

[0021] First, the to be shaped component body is put into the base 1 circular groove, the component should be completely embedded in the circular groove, so that the component bottom surface protruding platform with the base 1 upper surface flush, play a fixed component role, the circular groove depth is 4.0-5.0mm. The component is put into the base circular groove, the first leg positioning module 2 and the second leg positioning module 3 are loaded, the inner surface of the two is closely attached, forming an inner ring hole and an outer ring, the outer diameter of the inner ring hole is 5.5-6.5mm, the inner ring hole mainly plays a leg positioning role, so that the tool and the leg are closely attached, forming a package to the leg, the outer diameter of the outer ring is 19-22mm, which determines the bending shape of the leg. After the leg positioning module is loaded, the pressing block 4 and the positioning column 5 are loaded, the two are nested structure, can be loaded at the same time, the positioning column 5 is put vertically downward until it gently touches the component body surface. At this time, one hand holds the positioning column 5, the other hand presses the pressing block 4 downward, the lower surface of the pressing block 4 should be closely attached to the leg positioning module, so that the component leg changes from the vertical upward state to the upwardly inclined state, holds the pressing block 4 stable and holds the leg end to bend it upward, completes the whole action of leg forming.

[0022] The contents not described in detail in the utility model specification belong to the known technology of the person skilled in the art.
