Description

A kind of enamel-covered wire unwinding device

Technical field:

The present invention relates to and linear broadcast mechanism, particularly a kind of enamel-covered wire unwinding device。

Background technology:

Motor to use U-shaped line to be inserted in stator slot in producing, and then U-shaped line stitch welds, and makes U-shaped line form loop in the stator。U-shaped line needs to take long, process of going for a stroll in advance, and this process carries out on bender in shearing。This machine needs a preposition enamel-covered wire unreeling machine for line。Shear and be provided with batch (-type) folder thread drawing mechanism around bender, batch (-type) cutting mechanism, batch (-type) go for a stroll mechanism。Namely folder thread drawing mechanism is wanted quickly to be delivered to by the line of one section of fixed length on shearing mould, then returns and awaits orders, and cutting mechanism shears next fixed length line after then clamping line segment, this fixed length line is gone for a stroll by the mechanism that then goes for a stroll, and completes a samsara running。Pressing from both sides and then do next samsara operation after thread drawing mechanism is return, so folder bracing wire is intermittent, then unreeling machine is also intermittent for line。

Unwinding device is made up of coil of wire machine, line ball frame。Coil of wire machine is made up of frame, reel, motor transmission mechanism。Spool spindle is enclosed within frame both walls bearing block, spool spindle is connected by shaft coupling transmission with the output shaft of motor transmission mechanism, motor control assembly controls motor and makes batch (-type) unwrapping wire, motor intermittent rotary time, rundown time are at regular time and quantity, in order to do synchronous operation with shearing around bender folder thread drawing mechanism。Line ball frame is made up of frame, rectangular lines seat, two guide rods, two guide brackets, two upper glands。Two guide rods are round bar shape, and its bottom is separately fixed in two guide bracket medium pores, and two guide brackets split frame both sides and position fixing。In rectangular lines seat medium pore, fit fixes a copper wire sleeve, and the curved cross section of wire sleeve inner circle is poroid, and rectangular lines seat is respectively provided on two sides with the longitudinal hole of symmetry, and two dynamic engagement sleeves of longitudinal hole are in the inner circle of two guide rods。Rectangular lines seat lower surface abuts in two guide bracket upper surfaces, and its upper surface is positioned by gland on axle sleeve type, and upper gland is withstood on by the radial bolts screwed up in radial screw bore to be implemented on guide rod cylindrical to fix。After enamel-covered wire is drawn from the coil of wire reel, in lower oblique line through after rectangular lines seat wire sleeve medium pore, more oblique up introduce that the preposition wiring sheared around bender is recessed to be taken turns。Enamel-covered wire the coil of wire, wire sleeve, wiring is recessed take turns between unsettled lead-in wire line V-shaped, it is therefore an objective in order to can be tight shape by enamel-covered wire, it is ensured that batch (-type) line sending。Take turns if coil of wire tieline is recessed, then the inertia after bracing wire makes aerial wire laying section in lax shape, then shear the thread drawing mechanism next round folder bracing wire around bender and take length for non-quantitative, cause U-shaped line Length discrepancy。

This unwinding device has the disadvantage that: the intermittent rotary time of coil of wire machine is isometric, and when the coil of wire leading point diameter on reel is big, then unwrapping wire amount lead-in wire big, unsettled is lax even can pile line；When coil of wire leading point diameter is little, then unwrapping wire amount is little, lead-in wire is tight, can cause that to pinch line uneven, affects sheared length。

Unsettled lead-in wire at wire sleeve, frictional force that wiring is recessed to be taken turns is big, abrasion is relatively big, power consumption can be made to strengthen, unsettled lead-in wire coat of paint exists abrasion。

Summary of the invention:

It is an object of the invention to overcome drawbacks described above, it is provided that a kind of enamel-covered wire unwinding device。

The solution of the present invention is: include coil of wire machine, line ball frame, line ball frame includes frame, rectangular lines seat, two guide rods, two guide brackets, it is characterized in that: two guide rods of line ball frame upwardly extend, two guide rod height are higher than shearing around the recessed height taken turns of bender wiring, and transverse plate two side through hole is linked in two guide rod upper ends and implements fixing；The frame side of line ball frame fixes a pole, installs the signal receiver of a proximity induction switch at pole upper end, fixes the induction apparatus of a proximity induction switch in rectangular lines seat sidewall orientation corresponding to inductive switch signal receiver；Proximity induction switching signal receptor outfan, front relay, the time relay, rear relay, coil of wire machine electric power switch connect from A-P successively circuit。

It is an advantage of the current invention that: the coil of wire unwrapping wire amount on reel is uniform；During bracing wire, lead-in wire reduces with rectangular lines seat wire sleeve, the recessed frictional force of taking turns of wiring, reduces abrasion and bracing wire power consumption。
