Abstract

The utility model provides a combined assembly roller consisting of a roll shaft 1, a roll sleeve 2 and clamp nuts 3, wherein the roll shaft 1 extended from two ends of the roll sleeve 2 is processed with threads on which the clamp nuts 3 are arranged; the clamp nuts 3 are butted against two end surfaces of the roll sleeve 2 and provided with bolt pins 4 and 5 connected with the roll shaft 1; and strengthening glue is coated between the roll shafts 1 and the roll sleeve 2 as well as between the clamp nuts 3 and the threads of the roll shaft 1. Through the improvement on the combined roller structure, the roller can be reused, and the roll sleeve and the roll shaft are more convenient to disassemble and assemble, thus improving the utilization ratio of the roller and reducing energy consumption.

Description

A kind of combination assembling roll

Technical field

The utility model relates to milling train component technology field, relates in particular to a kind of roll that makes up assembling or install.

Background technology

At present, in the production of small-sized continuous rolling bar, light section and screw-thread steel, often a large amount of rolls that use are bimetallic composite rolls of solid roll or whole composite casting.Above-mentioned two kinds of rolls are as damaging, and because of the specification requirement of milling train, the car mill amount of its reparation is very little, and have more than is needed integral body that just needs is several times scrapped.Therefore, the life-span of roll is lower, and the waste of roll material is bigger.

Also useful at present mechanical type assembly roller, this roll mainly are by being assembled by roller shell and roll shaft.Its roll shaft can use repeatedly, and roller shell and roll shaft easy accessibility have improved the utilization rate of roll, have also saved metal material simultaneously.But there is the deficiency of following several respects in present assembly roller mode:

The mechanical type assembly roller, too complicated because of the setting of mechanical part on roll shaft, it is longer to take roll shaft, therefore effective active length of roller shell is shortened, and has influenced its serviceability.

Interference assembled assembly roller, the magnitude of interference is difficult during assembling grasps.Little and easily produce the loosening of roller, axle as the magnitude of interference between roll shaft and the axle sleeve; Then easily cause the cracking of crisp hard roller shell greatly as the magnitude of interference.

Bonded assembly roller easily causes and lost efficacy viscose glue that roller, cover are produced is loosening because of viscose glue is heated in hot rolling, thus the carrying out smoothly of influence of rolled operation.

Therefore, wish a kind of simple and practical and reliable combination assembling roll of design.

The utility model content

The purpose of this utility model is in order to solve the problem that the combinations thereof roll in use occurs, a kind of roll that makes up assembling to be provided.By to the structural improvement of assembly roller, roll mandrel can be used repeatedly, the dismounting of roll sheath and roll mandrel is more convenient, thereby has improved the utilization rate of roll material, has reduced energy resource consumption, simultaneously, has also improved the serviceability of roll.

The utility model by the following technical solutions.

Combination assembling roll of the present utility model is made up of roll mandrel 1 and roll sheath 2, roll sheath 2 is installed on the roll mandrel 1, be processed with screw thread on the roll mandrel 1 that stretches out at roll sheath 2 two ends, the clamp nut 3 that abuts against roll sheath 2 both ends of the surface is installed on it, the radially pin 4 and the axial pin 5 that connect roll mandrel 1 are installed on clamp nut 3; Scribbling reinforced glue 6 between the faying face of roll mandrel 1 and roll sheath 2 and between clamp nut 3 and roll mandrel 1 screw thread.

Roll of the present utility model is after the combination assembling, and its roll mandrel 1 and roll sheath 2 can not produce loosening in use, and roll sheath can disassemble from roll mandrel easily, and the use repeatedly of roll mandrel has improved the utilization rate of roll material.The utility model is simple in structure, assembling and convenient disassembly, and reliable operation has improved the serviceability of roll.

Description of drawings

Fig. 1 is the structural representation of the utility model combination assembling roll;

Wherein: the 1-roll mandrel, the 2-roll sheath, the 3-clamp nut, 4-is pin radially, the axial pin of 5-, 6-reinforced glue.

The specific embodiment

Followingly the utility model is elaborated with reference to accompanying drawing and embodiment.

With reference to Fig. 1 combination assembling of the present utility model roll structural representation, the utility model is made up of roll mandrel 1 and roll sheath 2, and roll sheath 2 has adopted interference fit to be installed on the roll mandrel 1.

Shaft position at roll mandrel 1 two ends that roll sheath 2 is installed is processed with screw thread, and the clamp nut 3 that abuts against roll sheath 2 both ends of the surface is installed on the screw thread; Several are installed perpendicular to roll mandrel 1 and connect the radially pin 4 of roll mandrel 1 on clamp nut 3, and the axial pin 5 that several are parallel to roll mandrel 1 and connect roll mandrel 1 is installed on clamp nut 3.

The utility model adopts 2-4 the vertical radially pin 4 that connects roll mandrel 1 is installed on the external diameter of two clamp nuts 3 in the specific implementation, and the axial pin 5 that 2-4 parallel connection roll mandrel 1 is installed on the end face of two clamp nuts 3.

During preparation clamp nut 3, under the condition that guarantees its fastening strength, that should process as far as possible is thinner, so that effective active length of roll sheath 2 satisfies rolling demand.Also scribbling stubborn glue 6 on the faying face of roll mandrel 1 and roll sheath 2 and on the screw thread of clamp nut 3 and roll mandrel 1.

Above-mentioned employed radially pin 4 and axial pin 5, and employed stubborn glue 6 all is for roll mandrel 1 and roll sheath 2 can be fixedly installed togather, so that it can not produce loosening or move, improve the serviceability and the reliability of assembly roller when rolling.

Roll sheath 2 of the present utility model can be selected the anti-wear performance excellent material for use, and its turnover rate is reduced; And roll mandrel 1 can be selected the material of mandrel good combination properties such as forged steel such as 45# for use, and roll mandrel can repeatedly be used repeatedly, saves metal material.At present, the utility model has been saved material and the utilization rate raising because of the long service life than nickel molybdenum infinitely chilled ductile cast iron roll.Reparation and replacing because of having reduced roll improve operating efficiency greatly, have also improved the overall operation rate of milling train simultaneously.

The utlity model has the advantage of making simple, assembling and convenient disassembly, dependable performance, and have production cost and reduce remarkable results such as operating efficiency raising.

The utility model is not limited to the foregoing description, in the scope that does not break away from the utility model design philosophy, can carry out various changes and modifications, and these variations all belong to protection domain of the present utility model.
