Abstract
The utility model provides a roller mechanism of an air compressor. The roller mechanism comprises a driving roller, two sides of the driving roller are respectively provided with a driven roller, each driven roller is provided with a driven roller bearing seat provided with a limiting adjusting cushion, the driven roller bearing seats are connected with the driven rollers through drivel shafts, each driven roller bearing seat is provided with a driven roller oil cylinder, and two sides of the upper end of the driving roller are respectively provided with a driving roller bearing seat provided with a limiting adjusting cushion which is connected with the driving roller through driving shafts. Driving roller bearing seats on two sides of the upper end of the driving roller are respectively provided with a driving roller oil cylinder, and two sides of the lower end of the driving roller are provided with various parts at the upper end of the driving roller symmetrical around the driven shafts. The roller mechanism has the advantages that the thicknesses of the limiting adjusting cushions of the driving roller bearing seat and the driven roller bearing seats are adjusted to compensate roller nominal diameter diminished quantity, and therefore repeated use of the driving roller and the driven rollers is achieved. In addition, the roller mechanism has the advantages of being simple in structure, convenient to maintain, low in production cost, high in roller using rate, and the like.
Description
Technical field
The utility model belongs to the seamless steel pipe sky and subtracts machine tube reducing field, especially relates to the mill roll mechanism that a kind of sky subtracts machine.
Background technology
In existing technology, seamless steel pipe subtracts in the machine tube reducing field at rolling front sky, the wearing and tearing of roll in the operation of rolling, and pass can not adapt to the requirement of rolling mill practice again, and roll must be scrapped, and buys new roll, has the technical problem of the increasing of production cost.
Summary of the invention
Problem to be solved in the utility model provide a kind of simple in structure, change conveniently, the sky that roll can repeatedly utilize subtracts the mill roll mechanism of machine, is particluarly suitable for using in the operation of rolling of seamless steel pipe.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of sky subtracts the mill roll mechanism of machine, comprise initiatively roll, the both sides at the center of described active roll respectively are provided with a passive roll, respectively be provided with a driven roll bearing block on the passive roll of described active roll both sides, described driven roll bearing block is provided with the spacing adjusting pad of passive roll, described driven roll bearing block links to each other by driven axle with described passive roll, respectively be provided with a driven roll oil cylinder on the driven roll bearing block of described active roll both sides, the both sides of described active roll upper end respectively are provided with an initiative roll shaft bearing, described initiative roll shaft bearing is provided with the initiatively spacing adjusting pad of roll, described initiative roll shaft bearing links to each other with the active roll by driving shaft, respectively be provided with a drive roll oil cylinder on the initiative roll shaft bearing of both sides, described active roll upper end, the both sides of described active roll lower end are arranged with initiatively each parts of both sides, roll upper end about driven axle.
Further, described initiative roll shaft bearing links to each other by clamp with described drive roll oil cylinder.
Further, described initiative roll shaft bearing is positioned at sky and subtracts frame.
Advantage and the good effect that the utlity model has are: owing to adopt technique scheme, compensate the roll nominal diameter amount of diminishing by the thickness of adjusting the spacing adjusting pad of main driven roll bearing block, thereby realize the repeatedly use of main passive roll; Have simple in structurely, easy to maintenance, production cost is low, roll utilization rate advantages of higher.

The specific embodiment
As shown in Figure 1, a kind of sky of the utility model subtracts the mill roll mechanism of machine, comprise initiatively roll 1, the both sides at the center of described active roll 1 respectively are provided with a passive roll 2, respectively be provided with a driven roll bearing block 3 on the passive roll 2 of described active roll 1 both sides, described driven roll bearing block 3 is provided with the spacing adjusting pad 4 of passive roll, described driven roll bearing block 3 links to each other by driven axle 5 with described passive roll 2, respectively be provided with a driven roll oil cylinder 6 on the driven roll bearing block 3 of described active roll 1 both sides, the both sides of described active roll 1 upper end respectively are provided with an initiative roll shaft bearing 7, described initiative roll shaft bearing 7 is provided with the initiatively spacing adjusting pad 12 of roll, described initiative roll shaft bearing 7 is positioned at sky and subtracts frame 11, described initiative roll shaft bearing 7 links to each other with active roll 1 by driving shaft 8, respectively be provided with a drive roll oil cylinder 9 on the initiative roll shaft bearing 7 of both sides, described active roll 1 upper end, described initiative roll shaft bearing 7 links to each other by clamp 10 with described drive roll oil cylinder 9, and the both sides of described active roll 1 lower end are arranged with initiatively each parts of both sides, roll 1 upper end about driven axle 5.
The course of work of this example: during work, initiative roll shaft bearing 7 connects by clamp 10 with drive roll oil cylinder 9, the piston rod of drive roll oil cylinder 9 stretches out promotion initiative roll shaft bearing 7 and subtracts frame 11 interior movements at sky, realizes the rolling mill practice pass that requires by the thickness of adjusting the spacing adjusting pad 4 of passive roll and the spacing adjusting pad 12 of active roll.Roll pass lead, passive roll nominal diameter is from large to small the time, thickness main by adjusting, the spacing adjusting pad 4 of passive roll chock compensates the roll nominal diameter amount of diminishing, thereby realize repeatedly use main, passive roll, by changing main, driven roll oil cylinder depression stroke, after realizing that the roll nominal diameter changes, guarantee the constant of rolling mill practice pass.
More than an embodiment of the present utility model is had been described in detail, but described content only is preferred embodiment of the present utility model, can not be considered to be used to limiting practical range of the present utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the present utility model.
