Description

A kind of linear velocity equalizing device

Technical field

The invention belongs to machine design and manufacture field, a kind of linear velocity being specifically related to steel wire winding or unwinding equipment is equal Weighing apparatus device.

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 made up of " constant speed winding+minibreak " two action compositions frequently. But steel wire unreel motor set voltage, electric current drive under, its angular velocity is constant, along with the steel wire storage in reel Fewer and feweri, the diameter of residue wire loop is more and more less, and the linear velocity unreeled also decreases, and the linear velocity that steel wire unreels is After can be less than the linear velocity of wrapping machine, this has just broken the balance unreeling speed and speed of wrap, solves this problem in the past Typical scenario has three kinds:

One is artificial process, is manually frequently changed one of frequency of unreeling the input voltage of motor, electric current or alternating current and regulates Unreeling linear velocity, the most not only regulation is frequent, labor intensity is big, and the time cycle regulated, voltage, electric current or alternating current Frequency and Amplitude is also uneven, causes unreeling linear velocity and the most mathematically shows as that amplitude is inconsistent, the cycle Uneven disorderly jaggies, it is impossible to meet the high accuracy prescription of steel wire winding goods.

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, by the pipeline multiple-turns wound that is wound on assembly pulley, constitutes a current potential in the one end of " pendulum " Degeneration factor, during operation, assembly pulley can move back and forth the most up and down with the change of speed, precision can now unreel speed and twine in fact In the range of error allowed, balance is reached around speed.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 at the inclined rigid line goods of 173 more than MPa and 100m/min In Yi Xia low unreel speed for, particularly with steel wire unreel speed controlling for, dancing wheel method will appear as inferior position.

Three is magnetic powder cluth method, its agent structure be unreel connect between motor with unwrapping wire reel one magnetic powder clutched Device, the electric current that magnetic powder cluth is previously set controls to be wound around the moment of torsion of axle, and the minimum line speed concurrently setting wrapping machine is bigger In the maximum line velocity unreeled, keep speed when unreeling magnetic powder cluth when linear velocity does not catches up with speed of wrap and can skid Synchronize.But, along with steel wire storage on reel constantly reduces, winding radius is more and more less, be wound around traction moment of torsion also with Change big, be easily caused winding traction running roller be relative with steel wire and skid, also can break the balance unreeling speed and speed of wrap.Institute With the defect of magnetic powder cluth method it is also clear that.
