Description
Technical field
The utility model relates to a kind of planisher, especially a kind of single stand four-roller planisher that is used for smooth coil of strip after cold rolled annealed.
Prior art
At present, the large-scale four roller planishers of single chassis of each big steel company use of China all are that introduction is external or the cooperation manufacturing.Their common problems that exists are: 1. negative roller cylinder is installed on the back-up chock, causes roller cylinder bad seals easily, and easy-maintaining not.2. work roll changing adopts the dislocation roll change, has prolonged roll changing time, has reduced productivity ratio.3. the rolling absolute altitude adjustment technology of planisher is used step pad more, and it is to have level to adjust, and the height of each step differs 10～15mm, and rolling absolute altitude fluctuation range is ± 5～± 7.5mm, so its adjustment can not realize invariable.4. the flat cold-rolled sheet planisher does that dust usually sticks on the roll when smooth, needs frequent roll change, otherwise can influence the surface quality of smooth band, therefore the service life of having reduced working roll.5. the numerical value of band steel percentage elongation and milling train entrance velocity, muzzle velocity are relevant, and the adjustment percentage elongation need be known the accurate numerical value of tension force, if can not directly measure tension force and speed just must cause the control accuracy of percentage elongation not accurate enough.When particularly steel plate was thicker, the band steel did not pass the S roller, and the top roll of S roller is only as slewing rollers usefulness, and the cornerite between band steel and the slewing rollers is little, therefore was with must have skidding between steel and the roll surface and can't overcome.Prior art is put in photoelectric encoder on the S roller, calculate strip speed by the roller revolution, and skid between band steel and roll surface, thereby causing calculating, the revolution that will inevitably influence roller is with the speed of steel wrong, if the speed control of band steel is inaccurate, will influence the elongation control precision greatly, thus the mechanical performance of influence band steel.
Summary of the invention
The purpose of this utility model is exactly that a kind of single stand four-roller cold belt planisher that can the smooth band of production high accuracy will be provided, to improve band percentage elongation precision and lumber recovery, to reduce production costs.
Another order of the present utility model is to provide a kind of can shorten roll changing time, prolong negative curved cylinder service life, guarantee the constant single stand four-roller cold belt planisher of rolling absolute altitude.
The purpose of this utility model is to realize like this, this single stand four-roller cold belt planisher mainly comprises two memorial archways that are positioned at fore side and transmission side, top backing up roll, top working roll, bottom working roll and lower support roller are installed between two memorial archways, join by roll surface between the two neighbouring rollers, drive motors is installed at an end of working roll.Entrance side and outlet side at planisher are equipped with survey roller, pressure roller and a laser velocimeter instrument apparatus, survey under the bearing block of opening roller roller both sides tensometer is housed, and pressure roller adopts Driven by Hydraulic Cylinder.
In order to shorten the work roll changing time, boost productivity, reduce equipment cost, the utility model cancellation dislocation cylinder, and adopt elastic damper balance top working roll to realize the replacing working roll that do not misplace.For the ease of safeguarding and prolong the service life of negative curved cylinder sealing, the utility model design all is arranged in positive and negative roller cylinder on the cylinder piece, and has realized in the design that positive and negative bending roller force switches and be no dead band.In order to guarantee the constant of rolling absolute altitude, the utility model has adopted two hydraulic cylinders that have displacement transducer, drives respectively to go up wedge and the action of following wedge, thereby realizes the stepless adjustment of rolling absolute altitude.
The utility model has increased a survey roller at the entrance and exit of four roller planishers, opens the tension force that steel is with in the roller measurement by surveying, and directly adjusts rather than adjustment (prior art is indirect adjustment) indirectly, thereby has improved the elongation control precision.When the band steel does not pass the S roller, increase the method that laser velocimeter is directly measured strip speed by the entrance and exit at four roller planishers, having solved because of skidding between band steel and roll surface influences the problem of percentage elongation precision.Have advantages such as percentage elongation precision height, lumber recovery height, prolongation roll life cycle, can satisfy the requirement of the smooth band of high accuracy.
