Embodiment:
For further understanding content of the present utility model, Characteristic, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows.It should be noted that, the present embodiment is descriptive, is not determinate, can not limit thus protection range of the present utility model.
The special-purpose lead wire and earth wire hydraulic pressure of a kind of transmission line compression bonding apparatus, comprise that bar 2 is lifted on hydraulic tongs 6, left jig 5, right jig 8, a left side, bar 9 and U-bar guide rail 10 are lifted in the right side, hydraulic tongs passes through positioning seat 12 location and installation at U-bar guide rail middle part, at hydraulic tongs left and right side, be symmetrical arranged left jig and right jig, this left jig and right jig are respectively by the left coaster 13 sliding on U-bar guide rail, right coaster 11 sliding and runnings, and left jig, hydraulic tongs and right jig are distinguished made installing hole on same axis.Between left coaster and right coaster and groove steel rail, bearing 15 is all installed, left coaster and right coaster can be moved by slide block.On left coaster and right coaster, mirror image symmetry is all hinged with that bar is lifted on a left side, bar is lifted on the right side, and this left side is lifted bar, the right side and lifted Gan upper end and cut with scissors respectively and fill a binding ring 1, and this binding ring can be by pressing embedding locking mode by lead wire and earth wire 3 lockings.
Described left jig and right jig are all provided with locking clamp 14, and this locking clamp can be by its locking after left jig and right jig closure.For fear of the foreskin of injury lead wire and earth wire, in left jig and right jig are equal, be lined with rubber bushing (there is no label in figure).
Lead wire and earth wire in described left jig and right jig is coaxially separately installed with outward in left level divides minute restriction aluminum pipe 7 in restriction aluminum pipe 4 and right level, and these two aluminum pipes are the semi-circular tube that axis cuts, as the calibrator unit of steel pipe crimping.
The hydraulic tongs that the utility model does not describe in detail is prior art.
The utility model adopts the cross sectional shape of the as above lead wire and earth wire of connector presser crimping referring to Fig. 5, steel strand wire 20 joints of lead wire and earth wire adopt steel pipe 21 crimping to fix, the aluminum steel 18 of peelling off after foreskin 16 adopts 19 crimping of pressurized aluminum pipe to fix, and finally outside crimping point, puts rubber sleeve 17.
Working method of the present invention is:
1, install: before crimping, the U-bar guide rail that assembles the reinforcing of this device ，Jiang Zhong district lies on smooth location, and hydraulic tongs is put into U-bar guide rail, on guide rail, along guide-track groove, left and right coaster is installed, and on the coaster of left and right, jig is installed.
2, calibration: before putting lead wire and earth wire, pressurized aluminum pipe is penetrated to fluid die axle center, in left and right level, a minute restriction aluminum pipe is put into respectively left and right jig, pulls locking clamp and blocks respectively minute restriction aluminum pipe in left and right level, completes the centering leveling of jig.
3, steel pipe crimping: unclamp left and right jig, two need the lead wire and earth wire of crimping to peel off on request foreskin, in a lead wire and earth wire, be first set with sheath therein, then at pressurized aluminum pipe, then will after lead wire and earth wire, pass minute restriction aluminum pipe in the left and right level in left and right jig, the locking clamp of pulling left and right jig blocks respectively aluminum pipe. the steel strand wire of lead wire and earth wire are through steel pipe, after the mutual doubling of steel strand wire of two lead wire and earth wire articulates, be placed in the depressed position of hydraulic tongs; By steel pipe socket, at position, fold point, then Press Plier starts to press down; Due to the effect of lifting bar of two jigs, can make lead wire and earth wire remain level, steel pipe crimping process has displacement also can be eliminated along line slideway direction generation displacement.
4, aluminum pipe crimping: complete after steel pipe crimping, first remove minute restriction aluminum pipe in the level of left and right jig, the line of pressurized aluminum pipe is put into the depressed position of hydraulic tongs, pull the clamp spanner of right side jig, block the arranged on left and right sides of aluminum pipe, start to press a mould, unclamp rear to good left side two moulds that continue to exert pressure, when jig cannot block aluminum pipe on the left of overwhelming, add that in level, minute restriction aluminum pipe continues last mould of crimping left side.
5, suit sheath: sheath is sleeved on to the crimping position of aluminum pipe, and covers the foreskin of lead wire and earth wire, can complete the crimping of lead wire and earth wire.
