CLAMP FOR ROLLING MILL ROLL STAND

摘要

A clamp for releasably securing a rolling mill roll stand on a support structure, comprises a tubular housing adapted to be secured to the support structure. A piston subdivides the interior of the housing into front and rear chambers. A clamping jaw projects forwardly from the piston through an open front end of the housing. The piston is reciprocally movable between a locked position at which the clamping jaw engages the roll stand, and an unlocked position at which the clamping jaw is disengaged from the roll stand. Resilient elements act in the rear chamber to exert a locking force urging the piston into its locked position, and pressurized fluid acts in the front chamber to overcome the resilient locking force when unlocking the clamp.

1. A clamp for releasably securing a rolling mill roll stand on a support structure, said clamp comprising:
a tubular housing adapted to be secured to said support structure, said housing having a cylindrical interior extending along a central axis between a closed rear end and an open front end; a piston subdividing the interior of said housing into front and rear chambers; a clamping jaw projecting forwardly from said piston through the open front end of said housing, said piston being reciprocally movable along said axis between a locked position at which said clamping jaw engages said roll stand, and an unlocked position at which said clamping jaw is disengaged from said roll stand; resilient means acting in said rear chamber to exert a locking force urging said piston into said locked position; and fluid means acting in said front chamber to overcome said locking force to thereby urge said piston into said unlocked position.
