summary of the invention:
Technical problem to be solved by this invention is: overcome the deficiencies in the prior art, provide a kind of reasonable in design, simple in structure, stripping is effective and the cross-linked power cable semi-conducting layer peeling tool outside of high efficiency.
Technical scheme of the present invention is: a kind of cross-linked power cable semi-conducting layer peeling tool outside, contain framework ring, guide cover and end cap, the three is fixed together by connecting bolt, and, described framework ring is clamped between described guide cover and end cap, evenly be provided with three moving cutteves on described framework ring, be provided with stage clip between described moving cutter and described framework ring, a binding ring of suit on described framework ring, evenly be provided with three arc positioning grooves on the inner ring surface of described binding ring, 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 difference of two described location cambered surfaces, 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, be provided with bar hole on described knife rest, 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.Evenly be provided with three deep-slotted chip breakers on the outer ring surface of described binding ring, 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 invention has the beneficial effects as follows:
1, the present invention controls 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 binding ring of the present invention, 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, connects cambered surface and realizes the compression of moving cutter and overhanging, and the location cambered surface realizes the fixing position of moving cutter, has guaranteed cutting accuracy.
3, three of binding ring inner ring surface of the present invention 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 binding ring of the present invention and inner ring surface arrange, and the convenient operation person holds rotation.
5, the present invention is reasonable in design, simple in structure, stripping is effective and high efficiency, and it is applied widely, is easy to promotion and implementation, has good economic benefit.
the accompanying drawing explanation:
Sectional structure chart during stripping that Fig. 1 is the cross-linked power cable semi-conducting layer peeling tool outside;
Fig. 2 is A-A cutaway view in Fig. 1;
Sectional structure chart during not stripping that Fig. 3 is the cross-linked power cable semi-conducting layer peeling tool outside;
The outline drawing that Fig. 4 is cross-linked power cable semi-conducting layer peeling tool outside shown in Fig. 1.
embodiment:
Embodiment: referring to Fig. 1-Fig. 4, in figure, the 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.
The cross-linked power cable semi-conducting layer peeling tool outside contains framework ring 4, guide cover 1 and end cap 7, the 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, all be set with a moving cutter 2 in each through hole, moving cutter 2 consists of knife rest and cutter head, be provided with bar hole on knife rest, 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.A binding ring 8 of suit on framework ring 4, evenly be provided with three arc positioning grooves 9 on the inner ring surface of binding ring 8, 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 difference of two location cambered surfaces, the outer end of three moving cutteves 2 is all stretched out framework ring 4 and is laid respectively in three arc positioning grooves 9.
