Abstract
An indirect extrusion press has a die and die holder 20 and a sealing plate to close the billet carrier. After extrusion, a one-piece or two-part holding sleeve is placed between the sealing plate and the sealing stem and the latter is advanced to push the billet carrier over the die stem thereby expelling the sealing plate, the butt end of the billet, and the die holder into the sleeve. A shearing device then shears off the sealing plate and butt end, the second part of the holding sleeve moving aside with the sealing plate and butt end in it. The die holder is clamped in the holding sleeve which is pulled away from the billet carrier to separate the die from the extruded product. In the case of a one-piece holding sleeve, a transverse aperture is provided to allow the shearing operation.
