The modular cable cutter
Technical field
The present invention relates to a kind of modular cable cutter, be particularly useful for the modular cable cutter of twisted polyethylene cable head manufacturing process.
Background technology
At present, make in the engineering at the twisted polyethylene cable head, the stripping of main insulating layer and outer semiconducting layer is a very important and elaboration, and technological requirement is very high, particularly the section of outer semiconducting layer will link up, neatly very much, and any burr and uneven can not be arranged.This position electric field strength is the most concentrated, is the weakest place of cable end, and the common accident of cable end is caused by this position mostly.The quality of stripping quality directly influences the useful life of cable and the stability of safe operation.
At present, in construction, the quality of this link be by the workmen with common cable knife, control according to individual's technology and experience, how many technology quality, experiences of workmen differ greatly, uneven, be difficult to guarantee that a plurality of cable ends can both reach technological requirement.
Summary of the invention
The objective of the invention is in order to overcome the deficiency that existing traditional electrical cable end manufacture method is brought, a kind of modular cable cutter is provided, manufacture craft is low when having solved original manufacturing cable head, construction quality is uneven, thereby influences problems such as cable useful life and harm equipment safety operation stability.
For achieving the above object, the technical solution used in the present invention is as follows:
Modular cable cutter of the present invention, comprise upper bracket, lower carriage and blade, it is characterized in that: blade is packed on the swivelling tool-holder, the upper end of swivelling tool-holder and upper bracket flexibly connect, and are provided with screw in the upper bracket, are provided with screw rod in the screw, the screw rod upper end is connected with handwheel, the lower end is connected with the driving wheel support, and the driving wheel support is provided with driving wheel, and the position corresponding to driving wheel on lower carriage is provided with fast pulley.
Among the present invention, be provided with chute on upper bracket, swivelling tool-holder is slidingly connected by knife rest locking nut and upper bracket.
Among the present invention, also be provided with the moulding cutter on lower carriage, the moulding cutter is packed on the moulding cutter screw mandrel.
Because the present invention has adopted technique scheme, this modular cable cutter has fundamentally changed the scene, only need adjust the blade amount of feeding in the construction period and just can satisfy technological requirement fully, improved operating efficiency, reduced labour intensity, guarantee construction quality, obtained the effect of getting twice the result with half the effort.Particularly the personal safety to operating personnel plays a very good protection, and has really accomplished the work idea of " people-oriented, safety first ".

Embodiment
As shown in Figure 1 and Figure 2, modular cable cutter of the present invention comprises upper bracket 3, lower carriage 8 and blade 14, and blade 14 is packed on the swivelling tool-holder 13 by blade gland 16 and gland screw 15.Be provided with chute 18 on upper bracket 3, swivelling tool-holder 13 is slidingly connected by knife rest locking nut 12 and upper bracket 3, and the lower end of swivelling tool-holder 13 is connected with lower carriage 9 by blade carrier wheel 17.Be provided with screw in the upper bracket 3, be provided with screw rod 2 in the screw, screw rod 2 upper ends are connected with handwheel 1, and the lower end is connected with driving wheel support 4, and driving wheel support 4 is provided with driving wheel 5, and the position corresponding to driving wheel on lower carriage 9 is provided with fast pulley 7.
Among the present invention, also be provided with moulding cutter 6 on lower carriage 9, moulding cutter 6 is packed on the moulding cutter screw mandrel 11, and moulding cutter screw mandrel 11 is socketed in moulding knife rest 8 and the lower carriage 9.
The course of work of the present invention is as follows:
1, rotates adjustment screw rod 2, make driving wheel 5, fast pulley 7 suitably contact (compressing), can radially rotate in the cable outer semiconducting layer.
2, unclamp knife rest locking nut 12, adjust blade 14 feeding depths (deciding), must not injure main insulation on semi-conductive layer thickness.
3, this cutter is radially rotated the cut-out work of promptly finishing in a week, because the fastening effect of driving wheel 5 and fast pulley 7 can make the cutter seam dock fully to satisfy technological requirement.
4, in the time of need radially cutting off main insulation, can when cutter rotates, push down knife rest locking nut 12, make blade 14 ecto-entad feeding gradually, change and press in conjunction with finishing cut-out work.
5,, can finish the work of main insulation cut-out and the 45 ° of chamferings in end simultaneously, very efficient, safety by adjusting the amount of feeding of moulding cutter 6.
