<p>A shearing machine for cutting up material of any kind comprises a shearing blade carrier which is vertically slidable in a closed frame, being moved by a cylinder-piston assembly fixed in a crosshead of the frame. In order to simplify assembly and dismantling of the cylinder, the cylinder which is fixed in the crosshead, is supported against reaction forces from the blade carrier towards the crosshead by a divided ring on the side of the crosshead facing towards the blade carrier, the divided ring, engaging in a circumferential recess in the outside of the cylinder surface and also partly into an opening in the side of the crosshead facing towards the blade carrier and the cylinder is also fixed, on the side of the crosshead remote from the blade carrier by a second ring which bears against the crosshead with a prestress so that the cylinder is held under tension in the crosshead between the two rings.</p> |
