Description
(1) technical field
The invention belongs to a kind of spot dynamic balance technology, be specifically related to the dynamic balancing technics of 15 ° of inclination angle cantilevered complex profile revolving bodies.
(2) background technology
Be accompanied by the fast development of Chinese national economy, the building wire rod strengthens day by day with the steel demand, and the development of China's high speed wire rod finishing block equipment is very fast.20 beginnings of the century, my company actively cooperated with each big steel designing institute, and the 90m/s high speed wire rod finishing block group of producing is in leading domestic status, and domestic high line Equipment Market is in great demand.Laying head is one of visual plant in the high-speed rod-rolling mill production line, and main effect is a coil of stocking being told into 1050mm.
Laying head becomes horizontal layout, downward-sloping 15 °, is made up of a spinneret and a transmission device that is loaded on the rotation mandrel.The rotation mandrel is driven by dc speed-regulating motor by a pair of conical gear.Spinneret is to set the rotating speed rotation, and just can spue meets the stocking of external diameter requirement.Laying head rotation mandrel is made up of laying head and hollow shaft two parts, and laying head is used for fixing spinneret, and hollow shaft is in transmission case, by bevel gear driving.Because Laying head becomes 15 ° of inclination angles when finally installing with ground, and laying head partly is the expansion plate of archimedean space spiral, quickening along with rotating speed, the air drag that is subjected to is increasing, even if at Laying head output shaft assembly amount of unbalance on the dynamic balancing machine in the margin of tolerance, because the increase of air drag has caused the increase of centrifugal force, new imbalance has appearred, the Laying head vibration values is high, having had a strong impact on the mill speed of high-speed rod integral body, is spot dynamic balance and solve the above problem best bet that occurs.
(3) summary of the invention
The object of the present invention is to provide a kind of process that solves the Laying head spot dynamic balance with the Pu Lufu dynamic balance instrument.The present invention is safe and reliable, effectively improve Laying head dynamic balancing speed and precision, effectively reduces the vibration of Laying head and the process of noise.
Its processing step is: the balance quality that at first improves power shaft assembly, output shaft assembly; Use Pu Lufu VIBSCANNE type spot dynamic balance instrument again,, eliminate the inertia force and the inertia couple of rotor with the technology of two-sided spot dynamic balance.Spot dynamic balance technology concrete steps are as follows:
1, according to the architectural feature of Laying head, determine that two vibration measuring planes are selected on the bearings mounted height of output shaft, and sensor installation;
2, prediction: starter motor is measured vibration speed value, the phase value that original amount of unbalance causes by velocity sensor, vibration-measuring sensor;
3, calibration: test mass is fastened on (the A face is the laying head small end, and the B face is the inboard of weaving silk and coiling) on predetermined A, the B two sides respectively.Earlier the A face is calibrated, with quality, the phase value input dynamic balance instrument of test mass, vibration speed value, the phase value of Laying head take off A and interview heavy behind the starter motor measurement increase test mass; Again the B face is calibrated, heavy quality, the phase value of input B interview, starter motor measuring vibrations velocity amplitude, phase value take off the B interview and weigh.
4, at this moment on the dynamic balance instrument shown numerical value be exactly amount of unbalance size and phase place.According to showing, reality is increased quality, the phase place input dynamic balance instrument of counterweight respectively at A, the corresponding position of B face prewelding balancing weight.
5, start the Laying head dynamic balance instrument once more, test whether increase the weight of the position correct, how many remaining amount of unbalances is, the phase place that recomputates by dynamic balance instrument continues prewelding, reaches amount of unbalance in the margin of tolerance, finishes dynamic balancing.
Advantage of the present invention is: the balance quality height, vibration is low, noise is little, high efficiency, with strong points.
After adopting this process, avoided bad because of dynamic balancing, repeated disassembled and assembled equipment phenomenon has shortened the production cycle, has reduced dynamically balanced expense, has reduced the influence to producing and working, and also is the most effective scheme of field maintenance simultaneously.
