Description

Winding apparatus for joint of conducting wire

The utility model belongs to electric vehicle power supply trolley line joint fabrication tool.

When the contact net steel aluminum conductor of the electric vehicle power supply supply line that continues, China adopts the joint style of the curved butt joint of goat's horn usually.This joint style must curve goat's horn with the termination of two leads in the joint and bend.Adopt at present the manual winding apparatus of forming by the bolt of clamping lead as the upper and lower two clamping plates of moulded head and fixing cord.This manual winding apparatus, labour intensity height not only, it is curved nonstandard to bend the goat's horn that, and because the operation of this high labour intensity is the work high above the ground of being engaged on the tower wagon top, personal injury often takes place because of overexerting easily.

For reducing labor intensity, improve curved working (machining) efficiency of terminal goat's horn and quality, for guaranteeing operating personnel's personal safety, the utility model is proposed.

The utility model is made up of support, the working cylinder, moulded head and the alignment head that are installed on the support.Moulded head is made up of the mobile top that is installed in working cylinder piston bar external part, the locating wheel and the locating piece that are installed on the support.The alignment head is by being installed in the counterdie on the support and can moving under the effect of mobile top, and can take off The type patrix is formed. The top of type patrix has and moves the matrix face that the top shape matches, and is positioned on the same center line.

When the utility model is bent with the alignment operation in system, employing connects the working cylinder of power source, replace the hand active force with hydraulic action, thereby alleviated labour intensity, guarantee operating personnel's personal safety, the mobile top that is installed in during operation on the working cylinder piston bar external part can accurately reach the precalculated position, high efficiency, finishes the curved and alignment operation of system in high quality, thereby reaches the utility model purpose.

Below in conjunction with accompanying drawing the utility model is further elaborated.

The utility model is made up of support 1, working cylinder 2, moulded head 3 and the alignment 4 that be installed on the support 1.Moulded head 3 is made up of the mobile top 6 on the external part of the piston rod 5 that is installed in working cylinder 2, the locating wheel 7 and the locating piece 8 that are installed on the support 1, have the bottom 12 that matches with lead 11 top shape on 6 axial cross sections of mobile top, have periphery 13 and the top 14 that matches with lead 11 bottom shapes on locating wheel 7 and locating piece 8 axial cross sections; Alignment 4 is by being installed in the counterdie 15 on the support 1 and placing on demand or take away Type patrix 16 is formed,

Type patrix 16 has and moves top fulcrum 17 and two bottom fulcrums 19,20 that match with lead 18 bottom shapes that top 6 shapes match, and counterdie 15 has the top fulcrum 21 that matches with lead 18 top shape, working cylinder 2, move come directly towards 6, The center line of type patrix 16 and counterdie 15 is located along the same line.Back-moving spring 22 is installed in the working cylinder 2.When system is bent operation, make the mobile top 6 of piston rod 5 drives of working cylinder 2 be raised to peak, the need system bent-up end of lead 11 is placed on locating wheel 7 and the locating piece 8, and make the short end of lead 11 be positioned at locating wheel 7 sides, the push the work forward piston rod 5 of cylinder 2 of the pressure medium that enters through the hole 23 of working cylinder 2 drives and moves top 6 and move down, and compression reseting spring 22, when the bottom 12 of moving top 6 contacts with lead 11, and after coincideing with it, piston rod 5 drives mobile top 6 and continues to move down into the precalculated position, and it is curved that the end of lead 11 is made desired goat's horn, open oil return valve, make piston rod 5 and on mobile top 6 withdrawal under back-moving spring 22 effect, take out lead 11.

When the alignment operation, will there be the curved point of curved lead 18 to place on the counterdie 15, and the top 5 of lead 18 and the top fulcrum 21 of counterdie 15 are matched, will

Type patrix 16 places on the lead 18, makes The bottom fulcrum 19,20 of type patrix 16 and the bottom of lead 18 match, and make

Type patrix 16 and the center line that moves top 6 are located along the same line, and the push the work forward piston rod 5 of cylinder 2 of the pressure medium that enters through the hole 23 of working cylinder 2 drives and moves top 6 and move down, and compression reseting spring 22, when the bottom 12 of moving top 6 with The top fulcrum contact of type patrix 16, and after coincideing with it, piston rod 5 drive move top 6, Type patrix 16 continues mobile precalculated position down, and with lead 18 alignments, opens oil return valve, make piston rod 5 and on mobile top 6 withdrawal under back-moving spring 22 effects, take out Type patrix 16 and lead 18 are finished the alignment operation.
