<p>Mechanised ingot branding punch for branding hot blooms, ingots, etc. of metal has a punch mechanism fitted with a piston positioned in a compressed air cylinder against a recuper-spring. Compressed air control is effected by means of a T-valve so that the piston is actuated by compressed air for punching, and discharge of the compressed air allows the recuperating spring to return the piston to its original position.</p> |
