Description
Technical field
The utility model relates to roll technology field, in particular to a kind of new roller with collars retaining mechanism.
Background technique
Currently, wearing no resistance since plain cast iron roll hardness is low, slot roll change is changed in production often, product size, table
Face mass change is fast, unstable, influences operating rate, the lumber recovery of production to a certain extent, restricts further increasing for production capacity,
In order to solve the above-mentioned technical problem, occurs composite roll in the market, it is good that composite roll possesses wearability, long service life, work
High feature is imitated, however, the material of axis is steel, and the thermal expansion coefficient of hard alloy since its collars material is hard alloy
Less than steel, and collars and axis are interference fit, using interference fit in use by the variation of temperature
It will lead to collars spalling.
Utility model content
The utility model provides a kind of new roller with collars retaining mechanism, is for existing collars and axis
Cooperation of being full of is assembled, and since collars material is hard alloy, the material of axis is steel, in use by the variation meeting of temperature
The problem of leading to collars spalling.
To achieve the goals above, the technical solution of the utility model is specific as follows:
A kind of new roller with collars retaining mechanism, including axis, carbide roll ring are coupled on the axis hard
Matter alloy collars, the carbide roll ring side are equipped with collars retaining mechanism.
The collars retaining mechanism includes gasket ring, pushing tow bolt, the bolt installation set with axial screw hole, the gasket ring and
Bolt installation set with axial screw hole is coupled on the shaft, and the gasket ring is located at the carbide roll ring one
Side, the bolt installation set with axial screw hole are located at the gasket ring side, the bolt installation set with axial screw hole
On be coupled several pushing tow bolts, pushing tow bolt one end holds out against the gasket ring.
The beneficial effects of the utility model are: the utility model is due to being that carbide roll ring is fit directly on axis, it is sharp
Carbide roll ring is positioned with collars retaining mechanism and is locked, there is certain fitting allowance, when encountering the factor of high temperature,
Will not due to expansion and there is a situation where collars be broken, wherein collars retaining mechanism is designed as by gasket ring, pushing tow spiral shell by we
The structural body that bolt, the bolt installation set with axial screw hole form, gasket ring and the bolt installation set with axial screw hole cooperate
It is mounted on axis 1, gasket ring is located at carbide roll ring side, and the bolt installation set with axial screw hole is located at gasket ring side, band
Several pushing tow bolts are coupled in the bolt installation set for having axial screw hole, pushing tow bolt one end holds out against gasket ring, then hard
Alloy collars is locked, and when carbide roll ring since long-time uses, when needing replacing, is only removed pushing tow bolt, is had
The bolt installation set and gasket ring of axial screw hole, can remove carbide roll ring, the short, labor intensity of workers with roll changing time
Low advantage, and reconditioning can use repeatedly, reduce production cost.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Wherein, 1. axis, 2. carbide roll rings, 3. gasket rings, the 4. bolt installation sets with axial screw hole, 5. pushing tow spiral shells
Bolt.
Specific embodiment
As shown in Figure 1, a kind of new roller with collars retaining mechanism, including axis 1, carbide roll ring 2, on axis 1
It is coupled carbide roll ring 2,2 side of carbide roll ring is equipped with collars retaining mechanism, and collars retaining mechanism includes pad
Ring 3, the bolt installation set 4 with axial screw hole, pushing tow bolt 5, gasket ring 3 and the bolt installation set 4 with axial screw hole are matched
Conjunction is mounted on axis 1, and gasket ring 3 is located at 2 side of carbide roll ring, and the bolt installation set 4 with axial screw hole is located at gasket ring 3 one
Side is coupled several pushing tow bolts 5 in the bolt installation set 4 with axial screw hole, and 5 one end of pushing tow bolt holds out against gasket ring 3.
The utility model needs replacing hard alloy applied in hot rolling ribbed steel bar, bar production after prolonged use
Collars 2 only removes pushing tow bolt 5, the bolt installation set 4 with axial screw hole and gasket ring 3, can be by carbide roll ring 2
It removes, has the advantages that roll changing time is short, labor intensity of workers is low etc., and reconditioning can use repeatedly, reduce production cost, due to
Carbide roll ring is positioned locked, tool using collars retaining mechanism by the elastic conjunction for having abandoned collars among traditional roll
Have certain fitting allowance, when encountering the factor of high temperature, will not due to expansion and there is a situation where collars be broken.
