DEVICE FOR PROCESSING OF A METAL STRIP IN A ROLL Russian patent published in 2019 - IPC C23G3/02 B21C47/30 

FIELD: metallurgy.

SUBSTANCE: invention relates to chemical processing of a metal strip in a roll. Device comprises a working bath in which a clamp is fixed for fastening the outer end of the strip, and a strip winding device, including a drum, equipped with a clamp for fastening the inner end of the strip, drum lifting mechanism and drum rotation mechanism. Drum is made with the possibility of changing its diameter in the form of a set of oppositely arranged jaws installed with the possibility of adjustable changes in the distance between the oppositely located jaws. Winding device is equipped with a mechanism for changing the distance between oppositely located drum jaws, and this mechanism comprises a tubular element inside which a control rod is installed, and the lower part of the tubular element and the lower part of the control rod are in pairs connected by upper and lower hinge links with each jaw respectively with the possibility of changing the distance between oppositely located jaws when the control rod moves inside the tubular element. Tubular element and the rod are connected to the drum rotation mechanism.

EFFECT: higher quality of processing of metal, mostly thin, strips, with technological solutions.
