utility model content:
Technical problem to be solved in the utility model is: overcome the deficiencies in the prior art, a kind of reasonable in design, simple in structure, stripping is effective and operating efficiency is high cross-linked power cable semi-conducting layer peeling tool outside is provided.
The technical solution of the utility model is: a kind of cross-linked power cable semi-conducting layer peeling tool outside, contain framework ring, guide cover and end cap, three is fixed together by connecting bolt, and, described framework ring is clamped between described guide cover and end cap, on described framework ring, be evenly provided with three moving cutteves, between described moving cutter and described framework ring, be provided with stage clip, on described framework ring, be set with a binding ring, on the inner ring surface of described binding ring, be evenly provided with three arc positioning grooves, the bottom surface of described arc positioning groove consists of the location cambered surface at two ends and middle connection cambered surface, the radius of curvature of two described location cambered surfaces is different, the outer end of three described moving cutteves is all stretched out described framework ring and is laid respectively in three described arc positioning grooves.
Described moving cutter consists of knife rest and cutter head, on described knife rest, be provided with bar hole, a connecting pin is set in described bar hole, and the two ends of described connecting pin are fixed on described framework ring, between the bottom surface, outer end of described connecting pin and described bar hole, are provided with described back-moving spring; Described cutter head is arranged on the inner of described knife rest.Described cutter head is that rib more than three is cone-shaped.Radially uniform three through holes on described framework ring, three described moving cutteves are separately positioned in three described through holes.On the outer ring surface of described binding ring, be evenly provided with three deep-slotted chip breakers, three described deep-slotted chip breakers and three described arc positioning groove interleaved arrange; The outer end of described moving cutter is provided with gland.
The beneficial effects of the utility model are:
1, the utility model is controlled the flexible of moving cutter by binding ring, thereby accurately cuts crosslinked cable, and ring cutting and rip cutting are coordinated to carry out, convenient and swift.
2, on the utility model binding ring, arc positioning groove is set, the inner surface of arc positioning groove is connected cambered surface and forms with one by two location cambered surfaces, the compression of the moving cutter of connection cambered surface realization and overhanging, location cambered surface realizes fixes the position of moving cutter, has guaranteed cutting accuracy.
3, three of the utility model binding ring inner ring surface arc positioning groove structures are identical, guarantee synchronized movement and the feeding accuracy of three moving cutteves, and firmly evenly, efficiency is high.
4, three arc positioning groove interleaved on three deep-slotted chip breakers on the outer ring surface of the utility model binding ring and inner ring surface arrange, and convenient operation person holds rotation.
5, the utility model is reasonable in design, simple in structure, stripping is effective and operating efficiency is high, and it is applied widely, is easy to promotion and implementation, has good economic benefit.

Fig. 2 is A-A cutaway view in Fig. 1;
Sectional structure chart when Fig. 3 is the not stripping of cross-linked power cable semi-conducting layer peeling tool outside;
Fig. 4 is the outline drawing of cross-linked power cable semi-conducting layer peeling tool outside shown in Fig. 1.
embodiment:
Embodiment: referring to Fig. 1-Fig. 4, in figure, 1-guide cover, 2-moves cutter, 3-gland, 4-framework ring, 5-connecting pin, 6-back-moving spring, 7-end cap, 8-binding ring, 9-arc positioning groove, 10-connecting bolt, 11-cross-linked power cable.
Cross-linked power cable semi-conducting layer peeling tool outside contains framework ring 4, guide cover 1 and end cap 7, three is fixed together by connecting bolt 10, and, framework ring 4 is clamped between guide cover 1 and end cap 7, wherein: radially uniform three through holes on framework ring 4, in each through hole, be all set with a moving cutter 2, moving cutter 2 consists of knife rest and cutter head, on knife rest, be provided with bar hole, a connecting pin 5 is set in bar hole, the two ends of connecting pin 5 are fixed on the hole wall of through hole, between the bottom surface, outer end of connecting pin 5 and bar hole, are provided with back-moving spring 6; Cutter head is arranged on the inner of knife rest.On framework ring 4, be set with a binding ring 8, on the inner ring surface of binding ring 8, be evenly provided with three arc positioning grooves 9, the bottom surface of arc positioning groove 9 consists of the location cambered surface at two ends and middle connection cambered surface, the radius of curvature of two location cambered surfaces is different, and the outer end of three moving cutteves 2 is all stretched out framework ring 4 and laid respectively in three arc positioning grooves 9.
Cutter head is that rib more than three is cone-shaped, can certainly be other shapes, determines as required, does not describe in detail one by one.In addition, be evenly provided with three deep-slotted chip breakers on the outer ring surface of binding ring 8, three deep-slotted chip breakers and three arc positioning groove 9 interleaved settings, be convenient to staff and grip rotation; The outer end of moving cutter 2 is provided with gland 3.
