Abstract
The invention discloses a manual spinning former of a metal sheath. The former comprises a former body, wherein a coupling is arranged at one end of the former body, and a feeding mechanism is arranged at the other end of the former body. The feeding mechanism is connected with a rotating wheel bracket; a rotating wheel shaft is arranged on the rotating wheel bracket; the rotating wheel shaft is used for driving a rotating wheel to rotate. The metal sheath of a high-voltage cable, manufactured by using the former, has a perfect 'trumpet' curve at the end opening and a smooth and flat surface; the electric field intensity at the position of the end opening of the metal sheath can be reduced, so that hidden danger of accidents can be avoided.
Description
Technical field
The present invention relates to high-voltage cable metal sheath field, be specifically related to a kind of Manual spinning metallic sheath former.
Background technology
The metallic sheath port of high-tension cable, it is one of maximum position of electric field strength, mishandlingly will make this position insulation breakdown, cause the serious accident that ground short circuit explodes, by construction process requirement, metallic sheath port should neat level and smooth impulse-free robustness, most importantly port position is made " loudspeaker " shape of outwards evenly expansion, to reduce the electric field strength at this position, stop accident potential.Did " loudspeaker " in the past and pulled back similar " loudspeaker " shape by workmen with pliers, although play a role, but fundamentally failing thoroughly to deal with problems, moreover it is very lack of standardization to pull out with pliers " loudspeaker " that come, does not meet technological requirement.
Summary of the invention
In order to solve the problem, the invention provides a kind of Manual spinning metallic sheath former.
Object of the present invention is achieved through the following technical solutions:
A kind of Manual spinning metallic sheath former, comprise body, described body one end arranges clutch, and the body other end arranges feed mechanism, and feed mechanism connects runner support, and runner support arranges runner shaft, and runner shaft drives runner to rotate.
Described runner shaft is arranged runner handle.
Described feed mechanism is the feed screw support be arranged on body and the feed screw be connected with feed screw support, feed screw is arranged feeding handle.
The present invention, by the effect of cooperatively interacting of clutch, runner and feed mechanism, in the mode of spinning on metallic sheath, makes it produce plastic deformation to reach the object of making " loudspeaker " shape port." loudspeaker " shape of the metallic sheath port using the present invention to make, smooth surface is smooth, and " loudspeaker " curve is perfect, can reduce the electric field strength of metallic sheath port position, stop accident potential.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
A kind of Manual spinning metallic sheath former, comprise body 6, described body 6 one end arranges clutch 1, and body 6 other end arranges feed mechanism, and feed mechanism connects runner support 4, and runner support 4 is arranged runner shaft 3, runner shaft 3 drives runner 5 to rotate.Described runner shaft 3 arranges runner handle 2.Described feed mechanism is the feed screw support 8 be arranged on body 6 and the feed screw 7 be connected with feed screw support 8, feed screw 7 is arranged feeding handle 9.
During specific works, first clutch 1 is inserted between metallic sheath 10 and cable insulation 11 inside metallic sheath 10, clutch 1 major part top margin is withstood to metallic sheath 10, rotating feeding handle 9 makes runner 5 hold out against outside metallic sheath 10, then left hand holds body 6, right hand rotation runner handle make 2 its radially rotate, in continuous spinning, metallic sheath 10 is constantly to external expansion, measure after a few, see whether metallic sheath 10 maximum outside diameter reaches 1.2 times of original diameter, whether surface is smooth, whether " loudspeaker " curve is perfect, spinning can not be continued completely again if still had, until reach standard.
