The garden node is no more than in 10 centimeters the distance outside distance alignment wheel and drop center wheel, is provided with the charging aperture parts, comprises handle, charging aperture base, charging aperture pressing plate.Just because of distance is near between charging aperture parts and the alignment wheel, so steel wire needn't knock alignment in advance by hand, just can directly enter material drag mechanism and aligning mechanism from the charging aperture parts, save time, reduce labor intensity.
On the charging aperture base, be provided with breach, inlayed the wear-resisting garden of carbide alloy cylinder on three directions of breach, be convenient to steel wire and pass through smoothly, prolong charging aperture service life.Also be provided with 2 screws, corresponding with the bayonet socket and the through hole of charging aperture pressing plate.Be provided with bayonet socket on the charging aperture pressing plate, the position of bayonet socket is corresponding and adaptive with the screw of charging aperture base, and another screw that also is provided with 1 through hole and charging aperture base is corresponding and adaptive.
During the steel wire threading, turn charging aperture parts handle, unclamp screw, the charging aperture pressing plate is removed, put into steel wire in charging aperture base breach, cover the charging aperture pressing plate, tighten handle, so just the breach that the steel wire position is limited in the charging aperture base has suffered.Steel wire is continued to drag forward, in the middle of alignment wheel and drop center wheel, passes, tighten the clamping screw mandrel, head on slide block and drive drop center wheel and push away forward, until steel wire till clamped in the middle of alignment wheel and the drop center wheel.Carried out the chromium plating processing to clamping the screw mandrel surface, it is stuck by slide block when promoting to avoid clamping screw mandrel.
Alignment wheel is a follower, is fixed on the bearing of machine platen to move.Drop center wheel is a driving wheel, is subjected to motor-driven by gear mechanism; Can move with the slide block of its cooperation, slide block one end is clamped screw mandrel and promotes and can move, and the slide block other end is subjected to the elastic force effect of reseting pressuring spring, can move to reset.The gear mechanism that drives drop center wheel is selected large module gear for use.During the debugging coiling machine, the locus of slide block is worthy of careful study very much, when just having deactivated state, should be arranged to the slide block side vertical with the axial connecting line of two meshing gears.Because slide block reach and after the distance of moving in ± 5 millimeters scopes, the centre-to-centre spacing of two meshing gears changes much smaller especially, thus slide block move the transmission that does not influence large module gear.
When steel wire is clamped in the middle of alignment wheel and drop center wheel, connect motor power, drop center wheel rotates, and steel wire is just being promoted to move forward by the torque of drop center wheel.When steel wire process aligning mechanism, enter the line sending clamp mechanism and can accept its torque when continuing to move ahead, close the material drag motor, loosen the clamping screw mandrel, slide block is open under spring action, distance in the middle of alignment wheel and the drop center wheel increases, and the material drag mechanism state of deactivating is in order to avoid steel wire drags gear mechanism and the material drag motor rotates at a high speed.But the alignment wheel cooperates other alignment wheels to continue performance alignment effect as a part of subsequent processing.In other words, another innovative point of the present utility model has been used alignment wheel exactly for the service of tugboat mechanism, has simplified mechanism, compactness the space, provide cost savings.
When steel wire used up, release handle was removed the bayonet socket of charging aperture pressing plate from screw, change new steel wire.If before steel wire uses up, need to change the steel wire kind, then behind the steel wire shearing, continue to start coiling machine, after being used up, old steel wire feeds new steel wire in charging again.Repeat the production that above-mentioned steps enters next circulation.
