Description
Technical field
The utility model relates to lead wire and earth wire in work transmission line and continues with device, specifically earth wire linear splicing sleeve hydraulic die.
Background technology
Work transmission line path is longer, and spreading lead wire and earth wire construction need to be carried out the straight line construction that continues, and current earth wire linear pipe continues and all adopts the mode of hydraulic construction.
Adopt traditional hydraulic die to carry out hydraulic construction, pressing mold size is shorter, straight line splicing sleeve aluminum pipe is longer, and hydraulic pressure position and the operating sequence of the steel-core-aluminium of take hinge line steel core dock aluminum pipe are example, as shown in Figure 1, (in figure, 1-6 is according to the district that exerts pressure of the sequence notation of exerting pressure, 7 is aluminum steel, and 8 is steel pipe, and 9 is aluminum pipe, 10 for steel core) in have the aluminum pipe 9 of steel pipe 8 parts not press, this part is designated as not nip I; On aluminum pipe 9, have the N1 note place of printing to start to exert pressure, according to the order of exerting pressure of 1-6, a side pressure is pressed opposite side to the mouth of pipe again.In crimping work progress, easily cause stress to concentrate, edge unbalance stress, causes bending in straight line splicing sleeve aluminum pipe crimping process, reduces construction quality.
Utility model content
The shortcoming existing in order to overcome above-mentioned prior art, the purpose of this utility model is to provide a kind of lead wire and earth wire in transmission line straight line splicing sleeve hydraulic pressure anti-bending mould, effectively solve buckling problem in straight line splicing sleeve aluminum pipe crimping process, improved service quality and once become excellent rate.
In order to address the above problem, the utility model by the following technical solutions: the anti-bending mould of a kind of lead wire and earth wire in transmission line straight line splicing sleeve hydraulic pressure, comprises mold, bed die; In mold, be provided with in liner, bed die lower liner is installed; The lower surface of upper liner, the upper surface of lower liner are provided with the crimp groove of mutual correspondence;
The left and right sides of described bed die connects respectively a bracket, the upper surface of each bracket arranges respectively one for holding in the palm the bracket of putting splicing sleeve, described bracket is coaxial with the crimp groove of lower liner, and the bottom surface that lower liner is installed in the bottom surface of bracket and bed die is positioned at same plane
The left and right sides of described mold connects respectively a pressure rack, the lower surface of each pressure rack arranges respectively the indent that a pressure is put splicing sleeve, described indent is coaxial with the crimp groove of upper liner, and the end face of installing liner in the end face of indent and mold is positioned at same plane.
Further technical scheme: it is semicircular groove that described bracket, indent are cross section.
Further technical scheme: one end of described bracket is connected in the left and right both ends of the surface of bed die by high-strength bolt; One end of described pressure rack is connected in the left and right both ends of the surface of mold by high-strength bolt.
The beneficial effects of the utility model are: it respectively installs a bracket, pressure rack in original pressing mold both sides, increase the area contacting with splicing sleeve in crimping process, having solved earth wire linear splicing sleeve hydraulic pressure exerts pressure and causes crooked quality problems, effectively raise the quality that earth wire linear continues, improved the excellent rate of once one-tenth of construction, avoided doing over again, improved conductor compression jointing operating efficiency.And simple in structure, portably use conveniently.
