Abstract
The utility model discloses a combined roller, including the roller, install lining pipe on the roller, the last cooperation of lining pipe has a plurality of axial arrangement's roller subassembly, leaves buffer clearance between the two adjacent roller subassemblies in a plurality of roller subassemblies, is equipped with the buffering plate mat in the buffer clearance, and buffering plate mat both sides are equipped with a plurality of location toper teeth, and roller subassembly lateral wall is equipped with and fixes a position toper tooth matched with taper hole, and the lining pipe both ends still are equipped with to tightly at the (holding) chuck at a plurality of roller subassembly both ends, are equipped with the fitting pin on the (holding) chuck. The utility model has the advantages of simple and reasonable structure, installation convenient to use adopts a plurality of roller subassemblies and in the design of clearance fit in buffering plate mat, is difficult for among the the rolling process influenced by high temperature and taking place deformation, has better wearability, stability and shock resistance simultaneously, has lengthened life effectively, has improved rolling effect and production machining efficiency.
Description
Technical field
The utility model relates to steel production and processing parts, is specially a kind of composite (back-up) roll.
Background technology
Roll is the strength member on steel rolling mill's rolling mill, utilize a pair or one group of roll rolls time the pressure that produces to roll stone roller steel.Dynamic And Static Loads when it mainly bears rolling, the impact of wearing and tearing and variations in temperature.Existing roll structure is reasonable not, and wearability is not good, heat-sinking capability and less stable, and anti-pressure ability is not enough, in the operation of rolling by temperatures involved the phenomenon that easily deforms, service life is shorter, influence of rolled effect and production and processing efficiency.
Utility model content
The purpose of this utility model is to provide a kind of composite (back-up) roll, reasonable not to solve roll structure traditional in prior art, wearability is not good, heat-sinking capability and less stable, anti-pressure ability is not enough, by temperatures involved and the phenomenon that easily deforms in the operation of rolling, service life is shorter, the problem of influence of rolled effect and production and processing efficiency.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of composite (back-up) roll, it is characterized in that: include roll shaft, described roll shaft is provided with lining pipe, described lining pipe is combined with the roller component of multiple axially-aligned, buffer gap is left between adjacent two roller components in described multiple roller components, buffering disc is provided with in described buffer gap, described buffering disc both sides are provided with multiple location conical tooth, described roller component sidewall is provided with and the taper hole of locating conical tooth and matching, described lining pipe two ends are also provided with the chuck being pushed against multiple roller component two ends, and described chuck is provided with locking pin.
Described a kind of composite (back-up) roll, is characterized in that: the roll surface of described roller component is provided with alloy wear-resisting layer.
The beneficial effects of the utility model are:
The utility model is simple and reasonable, easy to install, adopt multiple roller component and in gap, coordinate the design cushioning disc, temperatures involved is not subject to and the phenomenon that deforms in the operation of rolling, there is good wearability, stability and impact resistance simultaneously, effectively extend service life, improve effect of rolling and production and processing efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As shown in Figure 1, a kind of composite (back-up) roll, include roll shaft 1, roll shaft 1 is provided with lining pipe 2, lining pipe 2 is combined with the roller component 3 of multiple axially-aligned, buffer gap is left between adjacent two roller components in multiple roller component 3, buffering disc 4 is provided with in buffer gap, buffering disc 4 both sides are provided with multiple location conical tooth 5, roller component 3 sidewall is provided with and the taper hole 6 of locating conical tooth 5 and matching, lining pipe 2 two ends are also provided with the chuck 7 being pushed against multiple roller component 3 two ends, and chuck 7 is provided with locking pin 8.The roll surface of roller component 3 is provided with alloy wear-resisting layer.
Claims (2)
