Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the invention is elaborated.
The making processing of dropper generally comprises two steps, is first line sending, and concrete technology flow process is as follows:
Electrical controller (1) sends line sending signal and parameter information to other devices, left copper sleeve pusher (3) is moved to the left stop of left 300mm stroke straight-line motion module (3-4), dropper length control device (5) and right copper sleeve pusher (4) all move to left stop separately, start left copper sleeve clamping lever cylinder (3-1) and right copper sleeve clamping lever cylinder (4-1) and clamp respectively left copper sleeve (10) and right copper sleeve (11); The copper stranded conductor of outsourcing is cut (2-5) by paying out machine (2-1), swage (2-2), line sending motor (2-3), wire conduit (2-4), electric hydaulic and is delivered to left electrical turntable (8-1), between left reverse wheel (8-2) and left thimble (8-3), pass, move on, through the left copper sleeve (10) being positioned on left copper sleeve pusher.
Copper stranded conductor continues to move ahead through after left copper sleeve (10), when left sensor (3-3) detects after copper stranded conductor, left line ball lever cylinder (3-2) is pushed down copper stranded conductor, then, left copper sleeve pusher (3) starts to move right with the identical linear velocity of line sending motor (2-3), traction copper stranded conductor moves right to its right stop, then left line ball lever cylinder (3-2) is removed line ball, now copper stranded conductor continues to advance to the right by the thrust of line sending motor (2-3), by metallic channel (14), then through right copper sleeve (11), because right copper sleeve is now positioned at the left stop of right copper sleeve pusher (4), cannot ensure smooth threading, may need human assistance.
Copper stranded conductor is through after right copper sleeve (11), when the right sensor (4-3) that is arranged on right copper sleeve pusher (4) detects after copper stranded conductor, right line ball lever cylinder (4-2) is pushed down copper stranded conductor, 1500mm stroke straight-line motion module (5-1) action in dropper length positioning device (5) simultaneously, promoting dropper length locating platform (5-2) moves right, speed is consistent with line sending motor (2-3), traction copper stranded conductor moves right the preseting length to dropper, then right copper sleeve pusher (4) continuation traction copper stranded conductor moves right to its right stop, at this moment right line ball lever cylinder (4-2) is removed line ball, then copper stranded conductor continues to advance to the right by the thrust of line sending motor (2-3), between right thimble (9-3) and right steering wheel (9-2), pass (may need human assistance herein), continue to advance to another preseting length to the right, now line sending completes.
After line sending is complete, just start concrete dropper and make, concrete technology flow process is as follows:
Electrical controller (1) sends signal to paying out machine (2-1) and line sending motor (2-3), stop unwrapping wire and line sending, while electrical turntable (9-1) to the right, right copper sleeve pusher (4) sends signal, at this moment right copper sleeve pusher (4) carries right copper sleeve (11) and is moved to the left to distance right thimble (9-3) 300mm place, pass right copper sleeve (11) in order to other end copper stranded conductor, right electrical turntable (9-1) action simultaneously, drive copper stranded conductor around right thimble (9-3) clickwise 1800 by right reverse wheel (9-2), copper stranded conductor has commutated around right thimble.
Copper stranded conductor is after right thimble (9-3) has commutated, electrical controller sends signal to right copper sleeve pusher (4), promotes right copper sleeve (11) and moves right and make it pierce into other end copper stranded conductor (may need human assistance herein).Two strands of copper stranded conductors all penetrate after right copper sleeve (11), right copper sleeve pusher (4) continues to promote right copper sleeve (11) and moves right (may need human assistance so that sleeve pipe moves right smoothly therebetween), until right copper sleeve (11) distance right thimble (9-3) opening part 4mm left and right, at this moment right hydraulic actuating cylinder (6-2) action, completes the crimping of right-hand member sleeve pipe.
Electrical controller (1) is cut (2-5) to electric hydaulic and is sent signal, and hydraulic shear (2-5) is cut off the copper stranded conductor of left end; Then electrical controller (1) left electrical turntable (8-1) send signal, left electrical turntable (8-1) drives copper stranded conductor along left thimble (8-3) clickwise 1800 by left reverse wheel (8-2), and copper stranded conductor has commutated around left thimble (8-3).
Electrical controller (1) sends signal to left copper sleeve pusher (3), promotes left copper sleeve (10) and is moved to the left and makes it pierce into other end copper stranded conductor (may need human assistance herein).Two strands of copper stranded conductors all penetrate after left copper sleeve (10), left copper sleeve pusher (3) continues to promote sleeve pipe and is moved to the left (may need human assistance so that sleeve pipe is moved to the left smoothly therebetween), until conduit distance left thimble (8-3) opening part 4mm left and right, at this moment the reserved end of copper stranded conductor is put into dropper tension force preinstall apparatus (7) fastening by human assistance, then the reserved end of left copper sleeve pusher (3) traction copper stranded conductor moves right, make after its tension force that reaches setting, left crimping cylinder (6-1) action, complete left copper sleeve (10) crimping.Then, 1500mm stroke straight-line motion module (5-1) drives dropper length locating platform (5-2) to move right, the dropper with certain tensioning is loosened, then manually take out dropper, reserve the back works such as the installation of end line nose and crimping, now dropper is made and is all completed.
Above the invention embodiment is had been described in detail, but described content is only for the preferred embodiment of the invention, can not be considered to the practical range for limiting the invention.All equalization variation and improvement etc. of doing according to the invention application range, within all should still belonging to the patent covering scope of the invention.
