Abstract
The utility model belongs to a combination roll of rolling metal section, it includes the roller, the roller shell and the tight nut essential element in top. The roller is characterized in that a conical surface 6 is arranged at the middle section of the roller shaft 1, a conical hole surface 7 is arranged in an inner hole of the roller sleeve 2, the conical hole roller sleeve 2 is sleeved on the conical roller shaft 1 and is positioned by a connecting key 3, a jacking nut 4 is arranged at one end of the roller shaft 1 to compress the roller sleeve 2, and a dismounting nut 5 is arranged at the other end of the roller shaft 1.
Description
The utility model belongs to the roll of shape.
Roll directly contacts with rolled piece when the rolled metal section bar.Especially the working face heat erosion of roll is serious in the course of hot rolling, and it is very fast to wear and tear.The working region on roll top layer is because of constantly being heated violent the expansion by the high temperature rolled piece simultaneously, and roll top layer and roll inside form the big temperature difference but the roll internal temperature rises slowly, causes the inside and outside coefficient of expansion difference of roll.Cause the accident of fracture of roller to happen occasionally.In process of production because rolling face is subjected to serious heat erosion and wearing and tearing, roll is scrapped with regard to whole after using to a certain degree, has increased production cost in addition.For solving above-mentioned drawback, once there were many people to invent various composite rolls in recent years, but not ideal.As: control golden composite roll complex process, it is too high to make difficult cost.The machinery composite roll again more adopts roll shaft and some ring-type roller shells to combine; As (application number " 91204708.9 " and application number are 8621012.7 etc.).Because the roll shaft diameter of combinations thereof roll significantly reduces than original diameter of common roll, be ring-type roller shell independently one by one and cover installs, lost whole resistance to bending.The mechanical strength of this assembly roller is lower than common roll on the contrary.Owing to they are not that the employing circular cone cooperates but the cylinder cooperation, requirement on machining accuracy is very high again, and mounting or dismounting and adjustment are all very difficult, and axiality is difficult to again guarantee, can not applies so far.
The purpose of this utility model provides a kind of mechanical strength height, and axiality is good, the alloy combination roll that easy whole taper hole roller shell of mounting or dismounting and taper roll shaft are complementary.
The purpose of this utility model realizes with following proposal: taper surface is processed in the stage casing of roll shaft, the roller shell endoporus is processed into the taper hole face, taper hole roller shell encapsulation on the taper roll shaft, by a connecting key the two is located, be provided with one at an end of roll shaft and hold out against nut, roller shell is compressed, be provided with one at the other end of roll shaft and tear withdrawing nut open, for the usefulness of dismounting roller shell.
Because taper hole roller shell of the present utility model is the complete heavier walled fitting of root, itself just possesses very strong bending resistance.Supportingly become its mechanical strength when whole and axiality when it and taper roll shaft are tight all considerably beyond existing assembly roller.Because this roll is to be formed by axle and the two suit of cover, when roller shell is heated, can freely do certain radial and axial expansion again, can be disconnected roll shaft support, overcome the inside and outside coefficient of expansion great disparity of common roll and produced phenomenon of rupture.The utility model is a cone match in addition, and requirement on machining accuracy is very not high, and adjustment holds out against nut 4 and also can reach original design standard.
The utility model is concentrated the alloy material of hot favorable working performance and is used to have only whole roll 1/4 heavy working roll to put, and has reduced cost and has prolonged service life.In process of production because of normal wear and reparation, when roller shell can not use, also only change weight and be 1/4 roller shell, weight is that 3/4 roll shaft then can use repeatedly.
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is the whole profile of the utility model alloy combination roll.
Among the figure: the 1st, the taper roll shaft; The 2nd, the taper hole roller shell; The 3rd, connecting key; The 4th, hold out against nut; The 5th, tear withdrawing nut open; The 6th, the roll shaft taper surface; The 7th, roller shell taper hole face.
Common roll material is made taper roll shaft 1, and taper surface 6 is processed in roll shaft 1 stage casing.Alloy material with the hot rolling favorable working performance is processed into taper hole roller shell 2, and roller shell 2 endoporus are processed into taper hole face 7, and taper surface 6 is identical with taper hole face 7 taperings.Relative position at taper roll shaft 1 and taper hole roller shell 2 studs with connecting key 3, and taper hole roller shell 2 is enclosed within on the taper roll shaft 1, connecting key 3 with both the location, will hold out against nut 4 again and compress roller shell 2 to the precession of roll shaft major part, the alloy combination roll.Remove earlier when changeing roller shell 2 and hold out against nut 4, will tear the microcephaly precession of withdrawing nut 5 again open to taper roll shaft 1.The dismounting task can be finished from taper roll shaft 1 in taper hole roller shell 2 tops.
Claims (1)
1, a kind of alloy combination roll, it comprises roll shaft, roller shell and holds out against the nut critical piece, it is characterized in that: there is taper surface 6 in roll shaft 1 stage casing, roller shell 2 endoporus are taper hole faces 7, taper hole roller shell 2 is enclosed within on the taper roll shaft 1, by connecting key 3 location, roll shaft 1 termination holds out against nut 4 and compresses roller shell 2, and roll shaft 1 other end is torn withdrawing nut 5 open.
