Example Embodiment

[0027] Such as figure 2 As shown, the closing tooling of the present invention includes: compression sleeve 1, screw sleeve 2, spring 3, screw cover 4, top block 5, etc., in which:

[0028] Such as image 3 with Figure 4 As shown, the pressing sleeve 1 is the main part of the entire closing tool, which is a revolving body, and the remaining components of the closing tool are installed on the left side of the inner shape to ensure that the bottom plate is close to the shell during the closing process. The right side is matched with the closing end of the filling valve 8 shell, and an inclined surface and a plane are set to ensure that when closing, the closing end of the shell first contacts the inclined surface, shrinks slowly, and then touches the plane to complete the closing work, ensuring that the shell is in the closing process Will not deform sharply and cause fracture.

[0029] Such as Figure 5 As shown, the screw sleeve 2 and the pressing sleeve 1 are connected by thread...

Abstract

The invention discloses a necking tool and necking method of a filling valve. The necking tool comprises a pressing sleeve, a screw sleeve, a spring, a screw cap and a top block, wherein the pressingsleeve is a rotary body, the screw sleeve is arranged on the left side of the pressing sleeve, the top block is arranged at the right end of the screw sleeve, the screw cap is arranged at the left endof the screw sleeve, the spring is arranged between the screw cap and the top block, and an inclined edge and a plane are arranged on the right side of the pressing sleeve and used for being matchedwith the necking end of a shell of the filling valve. Compared with the prior art, the necking tool and necking method have the positive effects that in the using process of the necking tool, and thedisposable necking of the shell of the valve is realized by using a press machine through the inclined plane and the plane matching the shell in the inner cavity of the pressing sleeve. Compared withthe necking tool in the prior art, the necking tool is obviously improved in the outer shape, the necking mode and the necking strength, the machining quality and efficiency are greatly improved, andthe labor intensity of an operator is reduced.

Description

technical field [0001] The invention belongs to the field of tooling design, and in particular relates to a closing tooling and a closing method for shell parts whose main structure is a thin-walled cylinder. Background technique [0002] In the field of valves, thin-walled cylindrical shells are very common parts in valve products. In the valve assembly process, valve components and springs need to be loaded into the shell, and the bottom plate is fixed by closing the parts. The structure is as follows: figure 1 As shown, it includes: housing 11, valve assembly 12, spring 13, bottom plate 14, closing part 15, etc. It can be seen from the figure that the spring force must be overcome when closing the opening to ensure that the shape and position tolerance of the mating surface of the housing and the valve assembly is maintained. If it is not closed properly, it will cause the thin wall of the shell to break or the indentation of the valve core to be deflected, which will aff...
