Description
Technical field
The utility model belongs to machine design and manufacture field and in particular to a kind of linear speed of steel wire winding or unwinding equipment
Degree balancer.
Background technology
Such as in accurate metal spring manufacturing process, after steel wire coiler has been wound around, with constant speed, the number of turns specified
Need to cut off steel wire, i.e. the action of wrapping machine is to be made up of frequently " constant speed winding+minibreak " two action compositions.
But steel wire unreels motor under set voltage, electric current drive, and its angular speed is constant, with the steel wire storage in reel
Fewer and feweri, the diameter of remaining wire loop is also less and less, and the linear velocity unreeling also decreases, and the linear velocity that steel wire unreels is
The linear velocity of wrapping machine can be less than afterwards, this has just broken the balance unreeling speed and speed of wrap, solve this problem in the past
Typical scenario has three kinds:
One is artificial process, is manually frequently changed and unreels one of frequency of input voltage, electric current or alternating current of motor
Regulation unreels linear velocity, so not only adjusts frequent, high labor intensive, and the time cycle adjusting, voltage, electric current or exchange
The Frequency and Amplitude of electricity is also uneven, lead to unreel linear velocity mathematically show as over time amplitude inconsistent,
Cycle uneven disorderly jaggies is it is impossible to meet the high accuracy quality requirement of steel wire winding product.
Two is dancing wheel method, and its agent structure is vertically to connect a level in the rotating shaft of a rotating potentiometer
" pendulum ", installs assembly pulley in the one end of " pendulum ", by the pipeline being wound multiple-turns wound on assembly pulley, constitutes a current potential
Degeneration factor, during operation, assembly pulley voluntarily can move back and forth up and down with the change of speed, precision can now unreel speed and twine in fact
Reach balance around speed in the error range allowing.But, dancing wheel method is only applicable to secant modulus 173 below mpa's
The high speed of soft pipeline unreels, and for secant modulus in the inclined rigid line product of 173 more than mpa and 100m/min
In following low unreel speed for, particularly with steel wire unreel speeds control for, dancing wheel method will appear as inferior position.
Three is magnetic powder cluth method, its agent structure be unreel connect between motor and unwrapping wire reel one magnetic powder clutched
Device, is previously set the electric current of magnetic powder cluth to control the moment of torsion being wound around axle, the minimum linear velocity concurrently setting wrapping machine is bigger
In the maximum line velocity unreeling, when unreeling linear velocity and not catching up with speed of wrap, magnetic powder cluth can skid thus keeping speed
Synchronous.But, constantly reduce with storage on reel for the steel wire, winding radius are less and less, be wound around traction moment of torsion also with
Change big, be easily caused the skidding relative with steel wire of winding traction running roller, also can break the balance unreeling speed and speed of wrap.Institute
Defect with magnetic powder cluth method is also obvious.
