Abstract
The utility model provides a high speed line pre-finishing roller ring plastic-deformation preventing taper sleeve and belongs to the field of metal rolling. The high speed line pre-finishing roller ring plastic-deformation preventing taper sleeve is characterized in that 3-4 plastic-deformation preventing gaps are evenly arranged on the sleeve wall of the taper sleeve from a sleeve opening of the taper sleeve to bottom. The width of each plastic-deformation preventing gap is 0.15-0.2 millimeter, and the length of each plastic-deformation preventing gap is at least 100 millimeters. At present, in the process of replacing the taper sleeve of a high speed line pre-finishing roll line matched with a roll shaft, sometimes the cone angle of the taper sleeve is different from that of the roll shaft, the taper sleeve and the roll shaft are not hundred-percent matched with each other due to different manufacture companies. If the taper sleeve and the roll shaft are forcedly assembled together under the action of a certain pressure, the raw state of the taper sleeve or the raw state of the roll shaft can be certainly damaged so that metal stress can not be released. In addition, due to cold weather in the northern area in winter, the roll shaft is heated through lubricate oil so that the roll shaft can not be cooled down. But the taper sleeve is in the normal temperature. Temperature difference exists between the taper sleeve and the roll shaft. When the roll shaft expands with heat, the taper sleeve and the roll shaft can be hard to separate. Therefore, in the production process, a method of exploding the roll shaft is often adopted so that production cost is increased and huge waste is caused. Through adoption of the high speed line pre-finishing roller ring plastic-deformation preventing taper sleeve, the problems are solved.
Description
Technical field
The utility model belongs to the rolling field of metal.
Background technology
The tapered sleeve that the preparatory finish rolling line of high line cooperates with roll shaft need periodic replacement, in the replacing process, the tapered sleeve inwall is a conical surface, it is installed and used with the cooperation of the roll shaft of identical tapering.During installation, roll shaft and tapered sleeve are taked pressure fitted, and promptly the tapered sleeve inwall is pressed on the roll shaft with certain pressure, make them form a unitary rotation; But because the manufacturer is different, the tapering that occurs tapered sleeve and roll shaft sometimes is different, is not 100% cooperation; At this moment under the certain pressure effect, forcing the two to be combined together, certainly will cause wherein that a side previous status is destroyed, make the stress of metal to discharge, is exactly because the northern area wintry weather is cold in addition; Roll shaft is heated by lubricating oil, can't cool off, and tapered sleeve is a normal temperature, and equipment has the very big temperature difference; Roll shaft generation thermal expansion phenomenon, again that the two is separately just very difficult, in the production process; Often take the mode of fried roll shaft, make production cost increase, cause huge waste.
Summary of the invention
The purpose of the utility model provide a kind of for convenience detach, need not explode roll shaft, the preparatory finish rolling collars of a kind of high line that saves production cost preapres for an unfavorable turn of events and moulds tapered sleeve.
The purpose of the utility model is realized by mode once:
The preparatory finish rolling collars of a kind of high line is preapred for an unfavorable turn of events and is moulded tapered sleeve, it is characterized in that having 3～4 and preapring for an unfavorable turn of events and mould seam said on the tapered sleeve sleeve wall, being uniformly distributed with downwards from the running-on of tapered sleeve, and this width of moulding seam of preapring for an unfavorable turn of events is 0.15～0.2mm, and length is at least 100mm.
Beneficial effect
The utility model is provided with to preapre for an unfavorable turn of events on tapered sleeve moulds seam, makes the stress on the tapered sleeve that the space that discharges arranged, and has made things convenient for dismounting; Fundamentally solved the problem that the tapered sleeve dismounting is not got off; Also avoid fried roller accident, reduced production cost, improved operating rate and production utilization rate.
Description of drawings:
Fig. 1 is the structural representation of the utility model embodiment 1;
Fig. 2 is the structural representation of the utility model embodiment 2.
The specific embodiment:
Embodiment 1:
The preparatory finish rolling collars of a kind of high line is preapred for an unfavorable turn of events and is moulded tapered sleeve, it is characterized in that having 4 directions and preapring for an unfavorable turn of events and mould seam 3 said on tapered sleeve 1 sleeve wall, being uniformly distributed with downwards from the openend 2 of tapered sleeve, and this width of moulding seam of preapring for an unfavorable turn of events is 0.15～0.2mm, and length is at least 100mm.
Promptly preapre for an unfavorable turn of events and mould seam 3 the tapered sleeve sidewall evenly is divided into 4 equal portions.
Embodiment 2:
The preparatory finish rolling collars of a kind of high line is preapred for an unfavorable turn of events and is moulded tapered sleeve, it is characterized in that on tapered sleeve 1 sleeve wall, being uniformly distributed with 3 directions downwards from the openend 2 of tapered sleeve and preapring for an unfavorable turn of events and mould seam 3 said, and this width of moulding seam of preapring for an unfavorable turn of events is 0.15～0.2mm, and length is at least 100mm.
Promptly preapre for an unfavorable turn of events and mould seam 3 the tapered sleeve sidewall evenly is divided into 3 equal portions.
The tapered sleeve setting preapred for an unfavorable turn of events mould seam, like this, if the tapering of tapered sleeve and roll shaft is variant when mounted; Tapered sleeve will be along with anti-opening or the closed tapering that submits to roll shaft; Initiatively go to cooperate, be easy to dismantle tapered sleeve like this, avoid fried roll shaft accident to take place with roll shaft; Can practice thrift about 40 on roll shaft in 1 year, units up to a million economize on the use of funds.
Claims (2)
1. the preparatory finish rolling collars of high line is preapred for an unfavorable turn of events and is moulded tapered sleeve, it is characterized in that: on said tapered sleeve sleeve wall, be uniformly distributed with downwards from the running-on of tapered sleeve and have 3～4 and preapre for an unfavorable turn of events and mould seam.
2. the preparatory finish rolling collars of a kind of high line according to claim 1 is preapred for an unfavorable turn of events and is moulded tapered sleeve, it is characterized in that, the said width of moulding seam of preapring for an unfavorable turn of events is 0.15～0.2mm, and length is at least 100mm.
