Description
Technical field
The utility model relates to cold rolling industry and even moves back or zinc-plated unit side cut equipment, particularly a kind of monoblock type volume ball machine rotating-table apparatus.
Background technology
Volume ball machine is that to handle the slitter edge silk that circle shear shears used; In branch company's cold rolling mill, have and used volume ball machine technology on many main line units; It is the visual plant of unit post processing section, but the stuck normal use of always seriously perplexing all volume ball machines of rotating disk inordinate wear and mandrel, after using very short a period of time; Just must once overhaul or the rotating disk replacing, have only about 3 months the service life of part rotating disk.Unusual or the fault of the rotating disk of the volume ball machine material that can cause cutting edge must be reprocessed to road, back unit, and the road unit has strengthened pressure after giving, and causes seriously disorder of coil of strip logistics, and has increased cost.So the quality of volume ball machine directly has influence on the ordinary production of unit.
Volume ball machine structure is as shown in Figure 1, and 1a is the rotating disk positional cylinder, and 2a is a scissors, and 3a is the mandrel moving track, and 4a is a motor, and 5a is an oil cylinder, and 6a is a reduction box, and 7a is a mandrel, and 8a is rotating disk (it comprises the mandrel sleeve).Slitter edge silk head by mandrel and mandrel sleeve chucking after, mandrel rotates, and can be rolled into volume to the slitter edge silk, the mandrel withdrawal can realize unloading volume, can realize the recovery of slitter edge volume through the waste material bucket.
Because confidential the asking of volume ball can be rolled into volume to the slitter edge silk of all specifications, volume ball machine rotating disk and mandrel cooperate requirement the highest with the mandrel sleeve, if rotating disk or the wearing and tearing of mandrel sleeve; It is big that the gap can become; Then accelerated the wearing and tearing of mandrel sleeve or rotating disk, and every cover rotating disk or mandrel sleeve cost are about 100,000, so cost is high; And changing difficulty, is the problem of volume ball machine most critical so prevent rotating disk or mandrel sleeve wear problem.
In order to prevent rotating disk wearing and tearing and plucking, in the prior art, the one, increase the hardness of rotating disk liner plate, increase wearability, at present about the hardness requirement HRC63 of liner plate, the 2nd, improves the accuracy of manufacture of each liner plate, it is 0.05mm that the flatness of all liner plates requires.But along with the hardness of produce band steel improves constantly, and receive the influence of the factors such as variation of vibration equipment, associated device installation accuracy, just improve the hardness and the accuracy of manufacture of liner plate, can not satisfy on-the-spot user demand.
Because the inordinate wear of rotating disk liner plate and plucking problem, cause rolling up the ball machine unusual with go wrong frequently, had a strong impact on the cut edge progress of material of unit, cause seriously disorder of coil of strip logistics, and the production schedule of having delayed.
Preventing to roll up in the method for ball machine wear liner, prior art is all used the method that accurate adjustment gap and rotating disk adopt two journal bearings to support separately at present except improving the liner plate hardness and the accuracy of manufacture both at home and abroad.Wherein accurate adjustment gap L comprises the fit clearance of mandrel and mandrel sleeve, but along with equipment vibrations and wearing and tearing, this gap can not be finely tuned, and oil cylinder can be realized the location to rotating disk, but can not finely tune the position of rotating disk; Rotating disk adopts separately two deep groove ball bearings to support, though it can reduce the dial rotation resistance, when smaller, there is the stall phenomenon in it to Fei Biansi to its frictional force.
So the at present both at home and abroad used this method that prevents the unusual or fault of rotating disk has following shortcoming:
1, rotating disk adopts two journal bearings to support separately, and adopts split-type structural with the mandrel sleeve, when normally batching work; Different slitter edge coil diameters and slitter edge silk specification cause the frictional force of rotating disk is not of uniform size, so rotating disk rotates sometimes; Sometimes do not rotate, cause of the inordinate wear of limit silk, promptly will carry out integral replacing about every half a year rotating disk; The inordinate wear of rotating disk also makes the rotating disk unbalance stress, and shortened the service life of its bearing and sealing;
2, complex structure, difficult in maintenance, cause the repair time long, maintenance cost is high;
3, two of the mandrel sleeve distances between bearings are little, the poor stability of rotation, and have only about 6 months the service life of bearing; The mandrel sleeve is realized stretching out with oil cylinder and the location of two positions of withdrawing, but can not carry out the fine setting of particular location, causes the mandrel sleeve can not adjust with the elasticity that cooperates of mandrel, has the fault of edge silk and inordinate wear.
Summary of the invention
