Abstract
The utility model provides a ceramic shell inner shielding barrel reshaping tool of a vacuum arc-extinguishing chamber. The ceramic shell inner shielding barrel reshaping tool comprises a main body, wherein the lower part of the main body is a cylinder and a circular-platform-shaped groove is formed in the bottom face of the main body; the axis of the circular-platform-shaped groove is overlapped with the axis of the cylinder; the small end of the circular-platform-shaped groove is located in the main body. The ceramic shell inner shielding barrel reshaping tool is simple in structure, convenient to operate and safe and reliable to use; a ceramic shell is not easy to damage when a shielding barrel is overturned and reshaped and the shielding barrel is overturned and reshaped in a narrow space in the ceramic shell; the reshaping quality of the shielding barrel is guaranteed.
Description
Technical field
The utility model relates to a kind of flanging and restriking instrument, especially relates to a kind of vacuum arc-extinction porcelain shell inner shield cylinder shaping tool.
Background technology
In the time of existing thin-walled tubular piece shaping, especially when the shaping of vacuum arc-extinction porcelain shell inner shield cylinder, be difficult to ensure the quality of shaping, and in shaping process easy pressure break porcelain shell.
Utility model content
The utility model aims to provide a kind of vacuum arc-extinction porcelain shell inner shield cylinder shaping tool, its easy damaged porcelain shell not in shaping process, and can ensure the quality of upset.
The technical solution of the utility model is a kind of vacuum arc-extinction porcelain shell inner shield cylinder shaping tool, comprise main body, lower body part is cylinder, and there is truncated cone-shaped groove main body bottom surface, truncated cone-shaped recess axis overlaps with cylinder axis, and truncated cone-shaped groove small end is positioned at body interior.
Preferably, described truncated cone-shaped groove small end end face and sidewall junction are with round-corner transition.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As depicted in figs. 1 and 2, the utility model discloses a kind of vacuum arc-extinction porcelain shell inner shield cylinder shaping tool, comprise main body 1, main body 1 bottom is cylinder, there is truncated cone-shaped groove 9 main body 1 bottom surface, truncated cone-shaped groove 9 axis overlap with cylinder axis, truncated cone-shaped groove 9 small ends are positioned at main body 1 inside, the cylinder external diameter that ensures main body 1 bottom while specifically setting is less than porcelain shell 6 top internal diameters, ensures that the distance between the large end of truncated cone-shaped groove 9 and cylinder outer surface is less than the distance between shielding cylinder 4 upper port outsides and porcelain shell 6 inwalls simultaneously.
Preferably, the effect of shaping, with round-corner transition, can be realized better in truncated cone-shaped groove 9 small end end faces and sidewall junction.
Preferably, connecting portion 2 is arranged at main body 1 top, and connecting portion 2 connects external drive mechanism.
Preferably; also comprise clamping part; described clamping part comprises support claw 3; described support claw 3 is positioned at main body 1 below, on support claw 3 lateral surfaces, has cannelure, and shielding cylinder 4 lower port contact with the cannelure shaft shoulder; support claw 3 is fixed on the movable jaw 8 of chuck 7; can effectively clamp shielding cylinder 4, axial location shielding cylinder 4 in shaping process, protects porcelain shell 6 better simultaneously.
Preferably, truncated cone-shaped groove 9 buses are crossing with the bus of main body 1 lower cylindrical body, and the large end of truncated cone-shaped groove 9 and main body 1 lower cylindrical body junction are with round-corner transition.
As shown in Figure 3 and Figure 4, when use, get the shielding cylinder 4 that upper port climbs over limit, snap ring 5 is set in porcelain shell 6 and in shielding cylinder 4 upper port outsides, snap ring 5 and porcelain shell 6 inwall step place axial location, support claw 3 is fixed on the movable jaw 8 of chuck 7, regulate the distance between support claw 3, support claw 3 is stretched into from shielding cylinder 4 inside, while arriving desired location, regulate support claw 3 from inner fixed mask cylinder 4, make shielding cylinder 4 bottoms be positioned on the cannelure shaft shoulder of support claw 3 outer surfaces simultaneously, operating main body 1 moves downward, shielding cylinder 4 upper port are carried out to shaping, make to cover snap ring 5 tops after shielding cylinder 4 upper port shapings.When having ensured shielding cylinder 4 shaping, do not damage porcelain shell 6, can be smoothly by shielding cylinder 4 turning shapings in the inner narrow space of porcelain shell 6, and ensure the quality of shielding cylinder 4 shapings.
Certainly; the utility model also can have other various embodiments; in the situation that not deviating from the utility model spirit and essence thereof; those of ordinary skill in the art can make various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection range of the appended claim of the utility model.
