Abstract
The utility model relates to the technical field of roll-bending devices of rolling mills, and discloses a roll-bending device preventing the inner wall of a roll-bending cylinder body from being scratched. The roll-bending device comprises a piston rod (1), a copper sleeve (2), the cylinder body (3), a cylinder base (4) and a cylinder cover (5). The cylinder cover (5) is arranged at the upper end of the cylinder body (3), and the cylinder base (4) is arranged at the lower end of the cylinder body (3). The copper sleeve (2) is arranged in the cylinder body (3), the upper end of the copper sleeve (2) is arranged in a cavity body formed by the cylinder cover (5) and the cylinder body (3), and the lower end of the copper sleeve (2) is arranged in a cavity body formed by the cylinder base (4) and the cylinder body (3). The copper sleeve (2) is in interference fit connection with the cylinder body (3), and the piston rod (1) is arranged in the copper sleeve (2). The roll-bending device can prevent the cylinder body from being scratched, and greatly reduces production cost. The copper sleeve can be dismantled and maintained when being scratched, and if the copper sleeve can not be maintained, another copper sleeve can be re-machined and arranged in the cylinder body, and the field use effect is good.
Description
Technical field:
The utility model relates to mill roll bending device technique field, especially relates to a kind of roll-bending device that prevents that the roller inboard wall of cylinder block is scratched of the hot rolling mill roll device of Aluminum Plate and Strip.
Background technology:
At present, traditional roll-bending cylinder is that cylinder body directly is made on roller bending block or the bearing block, in case inboard wall of cylinder block is scratched, then needs roller bending block is pulled down from rolling-mill housing, or bearing block is pulled down from backing roll, then delivers to the machine repair workshop and carries out inwall reaming repairing.Because diameter of cylinder strengthens, so the piston rod external diameter need to be strengthened, again do a piston rod.Sometimes owing to be subjected to structural limitations, cylinder body can only do the finishing of trace, if repeatedly scratching appears in same cylinder body, then need to scrap this roller bending block or top backing up roll bearing block, so the labour intensity of being a worker like this is large, maintenance time is long, and the waste production cost.
Summary of the invention:
For the weak point that addresses the above problem, the utility model provides a kind of roll-bending device that prevents that the roller inboard wall of cylinder block is scratched, the roll-bending device of the edge shell type that can effectively reduce labor strength, save maintenance time, saves production cost.
In order to realize the foregoing invention purpose, the utility model adopts following technical scheme:
A kind of roll-bending device that prevents that the roller inboard wall of cylinder block is scratched comprises: piston rod 1, copper sheathing 2, cylinder body 3, cylinder seat 4, cylinder cap 5, and described cylinder body 3 upper ends are provided with cylinder cap 5, and cylinder body 3 lower ends are provided with cylinder seat 4; Be provided with copper sheathing 2 in the cylinder body 3, described copper sheathing 2 upper ends are arranged in the cavity of cylinder cap 5 and cylinder body 3, and copper sheathing 2 lower ends are arranged in the cavity of cylinder seat 4 and cylinder body 3; And copper sheathing 2 and cylinder body 3 be for interference fit is connected, and 2 li of copper sheathings are provided with piston rod 1.
Owing to adopt aforesaid technical scheme, the utlity model has following superiority:
A kind of method and device that prevents that the roller inboard wall of cylinder block is scratched is to inlay a copper sheathing at the roller cylinder body, and copper sheathing and cylinder body are interference fit, and piston rod is contained in the copper sheathing, and namely copper sheathing is equivalent to a new cylinder body.And then piston rod 1 is not directly contacted with cylinder body 3 between them, so just can avoid cylinder body to scratch, greatly reduce production cost.When scratching appears in copper sheathing, can dismantle copper sheathing, place under repair, if can't repair, then can again process a copper sheathing and be loaded into, on-the-spot result of use is good.
Description of drawings:
Fig. 1 prevents the structural representation of the roll-bending device that the roller inboard wall of cylinder block is scratched;
Among the figure: 1-piston rod, 2-copper sheathing, 3-cylinder body, 4-cylinder seat, 5-cylinder cap.
The specific embodiment:
As shown in fig. 1: a kind of roll-bending device that prevents that the roller inboard wall of cylinder block is scratched comprises: piston rod 1, copper sheathing 2, cylinder body 3, cylinder seat 4, cylinder cap 5, and described cylinder body 3 upper ends are provided with cylinder cap 5, and cylinder body 3 lower ends are provided with cylinder seat 4; Be provided with copper sheathing 2 in the cylinder body 3, copper sheathing 2 upper ends are arranged in the cavity of cylinder cap 5 and cylinder body 3, and copper sheathing 2 lower ends are arranged in the cavity of cylinder seat 4 and cylinder body 3; And copper sheathing 2 and cylinder body 3 be for interference fit is connected, and 2 li of copper sheathings are provided with piston rod 1.
During use, copper sheathing 2 is installed on the cylinder body 3, and their Relations Among is interference fit.Then piston rod 1 is installed in 2 li of copper sheathings, piston rod 1 does not directly contact with cylinder body 3, so just can avoid cylinder body to scratch, and greatly reduces production cost.
Claims (1)
