    摘要: A roll stand for a rolling mill, comprising: a support structure adapted to be fixed at a selected location along a mill center line. First and second work rolls are configured and arranged to roll products directed therebetween. The first work roll has roll necks journalled for rotation in bearings contained in first chocks, and the second work roll likewise has roll necks journalled for rotation in bearings contained in second chocks, with the first and second chocks of the work rolls being arranged in pairs located on opposite sides of the mill center line. The first and second chocks of each pair are connected to the support structure for pivotal movement respectively about parallel first and second connecting axes which extend in parallel relationship with respect to the axes of the rolls and orthogonally with respect to the mill center line. An adjustment mechanism is provided for simultaneously pivoting the first and second chocks of each pair in opposite directions about their respective connecting axes in order to symmetrically adjust the parting between the work rolls.

    摘要: A housingless rolling mill having an upper and lower work roll, upper bearing blocks and lower bearing blocks for supporting the upper and lower work rolls, and screw-down cylinders for pulling the upper and lower bearing blocks vertically toward each other. The screw-down cylinder is tiltable with the use of upper and lower spherical. Legs of the lower bearing block are turnable in a roll cross direction. Lower cross cylinders are provided at the lower bearing block, and upper cross cylinders are provided at the upper bearing block to enable the work rolls to cross at an angle .theta.. Thus, a strip material is rolled to a satisfactory shape and thickness with the upper work roll and the lower work roll crossing each other.

    摘要: In roll housings for rolling mills, it is desirable to be able to separate the top and bottom halves of the housing so as to be able to change the rolls. When the top and bottom halves are reassembled, they must be held firmly together to ensure correct operation of the rolling mill. It is proposed to have hydraulically-tensionable tie bars which are fixed in the lower half of the housing, and which grip the top of the upper half of the housing. Hydraulic fluid is applied to produce the tension, and the fluid pressure achieved is maintained throughout rolling operation. Such tie bars will normally be provided at at least four corners of a roll housing, and a single hydraulic circuit will supply fluid to all the bars. In addition, hydraulically operated jacks can be used to pivot the tie bars into and out of position, and these jacks can be operated from the same hydraulic circuit.The invention relates to a roll housing of divided construction with a removable housing cap and tie bar connections between the housing and the housing caps. Advantageously, the tie bars can be hydraulically stressed or prestressed for the operating state of the rollstand. The individual parts of the stand are thus prestressed by means of hydraulically elongated or extended tie bars. The rollstand is therefore provided with the stretch characteristics of an undivided rollstand.The extension force and therefore the elongation of the tie bar for releasing or stressing the tie bar was hitherto produced by hydraulic means and a screwthreaded nut was then screwed down for maintaining the tie bar in the extended and stressed state. This operation was performed manually or--in a more costly manner--by a hydraulically actuated ratchet drive. In this method, after tightening of the screwthreaded nut, the hydraulic pressure applied by the hydraulic extending device for the tie bars is discharged. To release the screwthreaded nut the extending device is again biased by hydraulic pressure medium and the screwthreaded nut is turned upwardly until the tie bar can be pivoted outwardly beyond the housing edge.Operation of the four screwthreaded nuts on each rollstand is awkward and time-consuming because the screwthreaded nuts, normally situated in the support sleeve of the hydraulic ring cylinder, can be actuated only through a slot in the support sleeve.It is the object of the invention to save the installation times required for extending and slackening the tie bars and therefore to reduce the time required for roll changing in such rollstands so as to provide further mechanization.To solve the problem it is proposed that the pressure medium which produces the prestressing forces can be supplied to or shut off from the tie bar heads of one or more rollstands through central means and the prestressing pressure continues to be applied to the tie bar head during rolling operation.In a further embodiment of the invention and independent of relieving the prestressing pressure, the tie bars of one or more rollstands can be pivoted outwardly together through central control, by means of hydraulic power.
