Description

Cylinder body fixes, on similarly hereinafter cylinder roll-bending device

Technical field

The utility model is related to cold rolling mill work roller roll-shifting device, more particularly to a kind of cylinder body fixes, on similarly hereinafter cylinder it is curved Roller arrangement.

Background technology

Edge thinning (also known as side drop) is the very important quality index of cold rolled silicon steel, more for electrical steel product It is crucial.Steel edge portion Reducing thickness is bigger, and band trimming amount is also bigger after rolling, and product lumber recovery is lower.Currently, edge thinning Control technology is the another technical barrier after cold rolled silicon steel produces relaying thickness control and Strip Shape Control.Using work roll shaft To roll shifting technology can effectively reduce silicon steel side drop and with plate it is poor, to improve the lumber recovery of product, while reducing energy consumption, energy-saving ring It protects.

The original 1500 silicon steel cold continuous rolling production line of Anshan iron and steel plant, cannot be satisfied current market to the high-precision requirement of product, To improve the competitiveness of product, one has carried out edge drop control transformation to 1500 cold continuous rolling of Anshan iron and steel plant again.

Invention content

The utility model in view of the above technical problems, propose a kind of cylinder body suitable for cold rolling mill work roller roll shifting fix, On similarly hereinafter cylinder roll-bending device.

To achieve the above objectives, it is achieved through the following technical solutions：

A kind of cylinder body fixes, on similarly hereinafter cylinder roll-bending device, including：Top working roll bending cylinder block, bottom working roll roll-bending cylinder Block, U-shaped fixed cylinder block, working position block, lower limit position block, upper limit position block, changing track for roll and controllable extensible Bar；

U-shaped fixed cylinder block is fixed with rolling mill body, and working end end face is provided with longitudinally perpendicular slideway；

Top working roll bending cylinder block and bottom working roll bending cylinder block slidable fit are in U-shaped fixed cylinder block working end end face On vertical slideway；

Wherein, it is both provided with changing track for roll on top working roll bending cylinder block and bottom working roll bending cylinder block, worked on milling train Roller and component slippage are assemblied on the changing track for roll of top working roll bending cylinder block, and milling train bottom working roll and component slippage are assemblied in down On the changing track for roll of working roll bending cylinder block, milling train top working roll and component and top working roll bending cylinder block longitudinal direction synchronizing moving, Milling train bottom working roll and component and bottom working roll bending cylinder block longitudinal direction synchronizing moving；

With mechanical cylinder block instead of Driven by Hydraulic Cylinder formula cylinder block, bottom working roll bending cylinder block is still top working roll bending cylinder block Hydraulic drive type；

Lower limit position block is set to the vertical slideway lower end extreme position of U-shaped fixed cylinder block working end end face；

Upper limit position block is set to the vertical slideway upper end extreme position of U-shaped fixed cylinder block working end end face；

Working position block is located at operation roll of mill working position in the middle part of the vertical slideway of U-shaped fixed cylinder block working end end face It sets；

Controllable telescoping rod one end is fixed with top working roll bending cylinder block, and the other end is fixed with bottom working roll bending cylinder block.

Using the utility model of above-mentioned technical proposal, working position is converted to roll change position：Top working roll bending cylinder block 1 is under Working roll bending cylinder block is all withstood on working position block.Instantly when working roll bending cylinder block rodless cavity is logical oily, due to dead weight, lower work Make roll bending cylinder block to drop back into lower limit position block, as controllable telescoping rod 8 constantly stretches out, top working roll bending cylinder block Start after being raised up to upper limit position block, stopping action, milling train is in roll change position.At this point, can be by changing track for roll by milling train Top working roll and bottom working roll pull out respectively.

Roll change position conversion work position：Top working roll bending cylinder block is withstood on upper limit position block, bottom working roll roll-bending cylinder Block is withstood on lower limit position block.Instantly when working roll bending cylinder block rod chamber is logical oily, due to dead weight, top working roll roll-bending cylinder BOB(beginning of block) is fallen after rise to working position block, and as controllable telescoping rod is constantly retracted, bottom working roll bending cylinder block is raised up to work After the block of position, stopping action, milling train is in working position.

The utility model advantage：

1, it can guarantee glacing flatness quality of strip during edge drop control；It is altered with mechanical synchronization, short stroke roll Roller system is combined, and functionally also has enough edge drop control amounts.

2, it is high to design simple, at low cost, fast response time, control accuracy for fixed roller structure.Previous working roll is positive and negative Bending cylinder block is to realize that positive and negative roller at least needs 8 groups of Driven by Hydraulic Cylinder formula bending cylinder blocks, and the device is simplified to only need 4 groups of machineries Formula cylinder block and 4 groups of Driven by Hydraulic Cylinder formula bending cylinder blocks.Either processing and manufacturing or system control, pipeline is safeguarded etc., and previous Structure is compared, and nearly 50% can be saved in cost, maintenance is convenient.

The above description is merely an outline of the technical solution of the present invention, in order to better understand the skill of the utility model Art means, and being implemented in accordance with the contents of the specification, and in order to allow the above and other purpose, feature of the utility model It can be clearer and more comprehensible with advantage, it is special below to lift preferred embodiment, and coordinate attached drawing, detailed description are as follows.
