Abstract
The utility model relates to the field of differential temperature treatment, in particular to a shaft end lengthening device of a minisize supporting roll. The shaft end lengthening device of the minisize supporting roll is characterized by comprising steel sleeves and shaft heads. The inner diameter of one end of each steel sleeve is matched with the end portion of the supporting roll, and the other end of each steel sleeve is connected with one shaft head in a matching mode, the diameter of each shaft head is matched with the size of a differential temperature furnace carrier roller. The length of each steel sleeve is between 500mm and 520mm, and the length of each shaft head is between 300mm and 330mm. compared with the prior art, the shaft end lengthening device of the minisize supporting roll has the advantages that the shaft end lengthening device is arranged at two ends of the minisize supporting roll and can be used repeatedly, and thus craft heads of the supporting roll are eliminated, waste of materials is avoided, and production cost is reduced.
Description
Technical field
The utility model relates to the differential temperature process field, relates in particular to a kind of axle head length extension device of small size support roll.
Background technology
Support roll need to use the differential temperature stove when differential temperature is processed, the two ends of support roll need frame on the carrying roller of differential temperature stove.Because differential temperature stove size is fixed, thus it overall dimension and the minimum size of treatable support roll also fix.Be that the differential temperature stove treated length of 4500mm support roll is when being the support roll of 3000mm left and right with processing shortest length, just support roll blank two ends need to be lengthened, elongated portion is as the technique head of support roll, the portion size that lengthens is the rod iron of two sections diameter of phi 500mm, long 750mm, weight is 2.31t, after differential temperature is processed, then the two ends technique head is cut, this has just caused a large amount of waste of material.
Summary of the invention
The purpose of this utility model is to provide a kind of axle head length extension device of small size support roll, is arranged on the two ends of small size support roll, can repeatedly recycle, and reduces waste of material, reduces production costs.
For solving the problems of the technologies described above, the technical solution of the utility model is:
A kind of axle head length extension device of small size support roll comprises steel bushing and spindle nose, steel bushing one end internal diameter and support roll end coupling, and the steel bushing the other end and spindle nose are connected, the size match of the diameter of spindle nose and differential temperature stove carrying roller.
The long 500-520mm of described steel bushing, the long 300-330mm of spindle nose.
Compared with prior art, the beneficial effects of the utility model are: this device is arranged on the two ends of small size support roll, can repeatedly recycle, and has eliminated the technique head of support roll, has avoided waste of material, has reduced production cost.
Description of drawings
Fig. 1 is that the utility model is implemented the status architecture schematic diagram.
Wherein: 1-small size support roll 2-steel bushing 3-spindle nose
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:
See Fig. 1, the axle head length extension device that is a kind of small size support roll of the utility model is implemented the status architecture schematic diagram, the two ends of small size support roll 1 arrange respectively length extension device, this length extension device comprises steel bushing 2 and spindle nose 3, steel bushing 2 one end internal diameters and support roll 1 end coupling, steel bushing 2 the other ends and spindle nose 3 are connected, the size match of the diameter of spindle nose 3 and differential temperature stove carrying roller.
For the specification of support roll, be that length extension device formulates unified standard, such as the axle head diameter of support roll is Φ 400mm, the internal diameter of steel bushing 2 is Φ 402mm, external diameter Φ 500mm, length 500-520mm, reduces deadweight.The outside diameter of spindle nose 3 is Φ 400mm, length 300mm, do not affect with differential temperature stove carrying roller and be connected, spindle nose 3 is connected by screw with steel bushing 2 grafting 20-50mm, during use, the axle head that the other end of steel bushing 2 is plugged into support roll can be put into the differential temperature stove and carry out differential temperature and process, processing after finishing is taken off length extension device for other support rolls, reduces waste of material, especially for support roll in enormous quantities, reduction effect is more obvious.
Claims (2)
