An enameled wire unwinding device

Abstract

A varnished wire unreeling device comprises a wire reeling machine and a wire pressing frame. The wire pressing frame comprises a machine frame, a rectangular wire base, two guide rods and two guide bases. The varnished wire unreeling device is characterized in that the two guide rods of the wire pressing frame extend upwards, the height of each guide rod is larger than that of a wiring concave wheel of a shearing bending machine, and the upper ends of the two guide rods are sleeved with through holes in the two sides of a transverse board and fixed by the through holes; a supporting rod is fixed to one side of the machine frame of the wire pressing frame, a signal receiver of an approaching inductive switch is installed at the upper end of the supporting rod, and an inductor of the approaching inductive switch is fixed to the position, corresponding to the signal receiver of the inductive switch, of the side wall of the rectangular wire base; the output end of the signal receiver of the approaching inductive switch, a front relay, a time relay, a rear relay and a motor power switch of the wire reeling machine are sequentially connected from front to back through circuits. The varnished wire unreeling device has the advantages that the coil unreeling amount of a reel is even; when a wire is pulled, the friction force of the wire and the rectangular wire base and the friction force of the wire and the wiring concave wheel are reduced, and therefore friction and wire pulling power dissipation are reduced.

Description

Technical field: [0001] The invention relates to a linear unwinding mechanism, in particular to an enameled wire unwinding device. Background technique: [0002] In the production of motors, U-shaped wires should be inserted into the stator slots, and then the U-shaped wires should be welded to make the U-shaped wires form a loop in the stator. The U-shaped wire needs to be lengthened and bent first, and this treatment is carried out on a shearing and bending machine. The machine needs an enameled wire unwinder to supply the wire. The shearing and bending machine is equipped with an intermittent clamping and pulling mechanism, an intermittent shearing mechanism and an intermittent bending mechanism. That is to say, the clamping and pulling mechanism should quickly send a section of fixed-length wire to the cutting die, and then return to stand by. The shearing mechanism clamps the wire segment and cuts the next fixed-length wire, and then the winding mechanism bends the fi...

Problems solved by technology

[0004] The defect of this unwinding device is that: the intermittent rotation time of the wire reel machine is equal in length, when the diameter of the wire coil lead-out point on the reel is large, the amount of wire unwinding is large, the suspended lead wire is loose, and even the wires will be stacked; If the diameter of the lead-out point of the coil is small, the pay-off amount will be small and the lead wire will be tight, which will cause uneven pinch wire and affect the cutting length

[0005] The friction force and wear of the floating lead wire on the wire sleeve and the wiring concave wheel are large, which will increase the power consumption and wear the paint leather of the floating lead wire
