Abstract
The utility model discloses an aligning roller of a combined type roller sleeve. The aligning roller of the combined type roller sleeve comprises a shaft (1), a roller body (2), a roller sleeve (3), space rings (4), keys (5) and a movable shaft (6), wherein the keys (5) are arranged between the space rings (4) and the roller body (2), as well as between the roller sleeve (3) and the roller body (2); the roller body (2) is sleeved on the shaft (1); the movable shaft (6) and the roller body (2) are fixed; the roller body (2) is sleeved on the shaft (1), and is connected and fixed through a bolt A (7); the movable shaft (6) and the roller body (2) are connected and fixed through a bolt B (8). The aligning roller of the combined type roller sleeve is high in hardness and abrasive resistance, replaceable and long in service life, so that the usage cost per ton steel is greatly reduced.
Description
Technical field
The utility model relates to machinery manufacturing technology field, the alignment roller that specifically a kind of steel rolling is used.
Background technology
Alignment roller is by the screw-thread steel shutting out in the rolling process head that aligns, the main transfer unit of equal length crop bundling cold bed, existing alignment roller is machining after monoblock cast, temperature while shutting out due to screw-thread steel is at 450 ℃-650 ℃, and the effect of the profile of tooth of screw-thread steel appearance, in use procedure, can produce following defect:
Temperature while one, shutting out due to screw-thread steel is at 450 ℃-650 ℃.Cast-in-block alignment roller is because the reason of cost and processing can not adopt high temperature alloy, so anti-wear performance is very poor, and average 2 first quarter moons will wear and tear, and cause integral body to scrap, and affect the production operational availability of whole piece steel rolling line.
Two, due to the effect of the profile of tooth of the screw-thread steel appearance shutting out, appearance wearing and tearing to roller shell can aggravate, blunt roller has seven output magazines, inhomogeneous due to what wear and tear, one of them groove wearing and tearing just causes whole blunt roller to scrap, alignment is changed will inevitably cause whole piece steel rolling line temporary cessation of production phenomenon, waste a large amount of human and material resources, financial resources.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned shortcoming and a kind of roller shell of providing is rigid and wearability is high and replaceable, and long service life greatly reduces the alignment roller of the combined type roller shell of ton steel use cost.
The alignment roller of a kind of combined type roller shell of the utility model, comprise axle, the body of roll, roller shell, spacer ring, key, moving axis, wherein: between spacer ring and roller shell and the body of roll, be provided with key, the body of roll is sleeved on axle and by bolt A and is connected and fixed, and moving axis and the body of roll are connected and fixed by bolt B.
The utility model compared with prior art, there is obvious beneficial effect, as can be known from the above technical solutions: the key filling on the body of roll and roller shell, spacer ring are bolted and are integrated, roller shell and spacer ring can not skid relatively with the body of roll, conveniently replaced after spacer ring or roller shell wearing and tearing, the time of reducing use cost and integral replacing.Greatly improve vulnerable part roller shell service life, and replaceable, change labour intensity and the low feature of rear current cost, greatly reduce a ton steel use cost.Blunt roller was brought up to 6-9 month by original 2-3 month service life, had reduced greatly and had stopped line maintenance frequency, had also improved the production operational availability of steel rolling line.
The specific embodiment of the present utility model is provided in detail by following examples.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model:
Fig. 2 is A-A cutaway view of Fig. 1.
Mark in figure:
1, axle; 2, the body of roll; 3, roller shell; 4, spacer ring; 5, key; 6, moving axis; 7, bolt A; 8, bolt B.
The specific embodiment
Below in conjunction with example, the utility model is described in detail, further explains and illustrate the technical solution of the utility model feature.
Referring to Fig. 1-2, the alignment roller of combined type roller shell, comprises axle 1, the body of roll 2, roller shell 3, spacer ring 4, key 5, moving axis 6, wherein: between spacer ring 4 and roller shell 3 and the body of roll 2, be provided with key 5, the body of roll 2 is sleeved on axle 1 and by bolt A7 and is connected and fixed, and moving axis 6 is connected and fixed by bolt B 8 with the body of roll 2.
During assembling, first key 5 and the body of roll 2 are assembled, then the body of roll 2 is placed on axle 1 and is connected and fixed by bolt A7, then spacer ring 4 and roller shell 3 are assembled on the body of roll 2, finally by bolt B 8, moving axis 6 is connected with the body of roll 2.
The above, it is only preferred embodiment of the present utility model, not the utility model is done to any pro forma restriction, any technical solutions of the utility model content that do not depart from, any simple modification, equivalent variations and the modification above embodiment done according to technical spirit of the present utility model, all still belong in the scope of technical solutions of the utility model.
