[0012] In this known system of mechanical / hydraulic adjustment devices, it has hitherto not been economical to dispense with the mechanical adjustment device and to implement the adjustment system as a purely hydraulic long-stroke adjustment device, since a correspondingly high pump is not provided. It is not feasible to achieve the required high adjustment speeds without the simple implementation of the power and at the same time hydraulic long-stroke adjustment devices

Embodiment Construction
[0037] Such as figure 1 As shown, the adjusting cylinder quick-adjustment device 9 according to the invention is designed as an integral component of the vertical rolling mill 10 . The vertical rolling mill 10 is used to vertically roll the edge of the rolling stock 11 introduced into the vertical rolling mill 10 in order to thereby selectively influence the width of the rolling stock 11 introduced during the further rolling process. For this purpose, the vertical rolling mill 10 comprises on one side at least one vertical rolling mill column 20 , which is connected to a column crosshead (Ständerquerhaupt, sometimes also called column crossbeam) 21 .
[0038] Furthermore, upper and lower uprights 22 and 23 are provided. The vertical roll unit 30 connected thereto basically consists of upper and lower vertical roll inserts 32 and 33 in which the vertical roll 31 is rotatably supported.
[0039] The roll forces transmitted to the vertical rolls 31 are balanced by means of the ...

The invention relates to an adjusting cylinder quick adjustment (9) for long, fast stroke movements in edging stands, at least consisting of edging stands (20), adjusting system, balancing system, andedging roll sets, comprising at least one piston each, which operates via edging roll chocks (32, 33) of at least one edging roll (31) on both sides for adjusting against the rolled material (11) andwherein the adjustment of the edging roll (31) can be actuated on each side hydraulically by means of a fluid and the adjusting cylinder quick adjustment (9) is fastened in the edging stand (20) andapplies the force required for the edging process. According to the invention, the adjusting cylinder quick adjustment (9) on each side of the edging stand (20) consists of at least one double cylinder (50), wherein the double cylinder (50) consists of two separately controllable cylinders, coupled to each other, and is designed first of all for quick adjustment and second of all for control adjustment of the edging roll (31).
Description
technical field [0001] The invention relates to a quick adjusting device (Anstellzylinderschnellverstellung) for long, fast stroke movements of an adjusting cylinder in a vertical rolling stand (Stauchgerüst), which consists of at least a vertical rolling mill column (Staucherständer), an adjusting system, a balancing system and a vertical Roll group (Stauchwalzensätzen) consisting of at least one piston, which acts on both sides via the vertical roll insert (Stauchwalzeneinbaustück) of at least one vertical roll for adjustment against the roll material and wherein the vertical roll is adjusted on each side Hydraulically actuated by means of a fluid and adjustable cylinder quick adjustment device is fixed in the vertical rolling mill column and applies the force required for the vertical rolling process. Background technique [0002] The adjusting device in the vertical rolling stand has the task of setting, maintaining and, if necessary, regulating the desired roll gap. Th...
