Method, control, and apparatus for taking up a billet produced in an extrusion or tube-making press includes applying a controlled pull-away tractive force, which keeps the emerging billet straight and does not affect the formation of the billet, increasing the pull-away tractive force in proportion to the extruded billet length, unit length weight and coefficient of friction between the billet and the delivery table, superimposing the pull-away tractive force upon the take-up tractive force det...

A puller for extrusion profiles at an extruder is disclosed including a carriage which is movable on rails along a runout conveyor for the extrusion profiles and at which a puller head with a fixed and a movable clamping jaw is arranged for pivotal movement about a vertical axis so that the puller head may be swung laterally out of the runout conveyor. The two clamping jaws extend approximately across the width of the runout conveyor, and the movable clamping jaw comprises a plurality of clampin...

Apparatus for pulling metal extruded from an extrusion machine has a pair of carriers mounted on one side and below the surface of a runout table. Each carrier moves on a rail parallel to the table. One carrier in an operative position does not interfere with the other in a retracted position when they pass each other. Production efficiency is improved by using the carriers alternately. With the rails below the level of the table surface, space above the runout table can accommodate apparatus to...

Device to draw extruded stock for an extrusion press, in which downstream of an extrusion press (11) is a withdrawal track (15) cooperating with two carriages (21) bearing engagement vices (24), an endless runway (20) being comprised in coordination with the withdrawal track (15) and having one segment (115) parallel to the withdrawal track (15) and bearing the two carriages (21), the endless runway (20) including two straight segments (115-215) and two connecting bends (22) and at least one swi...

An apparatus for cooling extruded profile sections comprises nozzles which are arranged above and below an exit path of the extruded profile section and which are formed as air nozzles arranged transversely of the pressing and exit direction of the extruded profile section and having slit-shaped nozzle openings. The air nozzles arranged beneath the exit path have a smaller nozzle slit width than the air nozzles arranged above the exit path and blowing onto the extruded profile section from above...

Apparatus for extrusion forging essentially comprises a double action hydraulic press composed of an inner ram. Extrusion forging of a billet is accomplished by placing the billet in a container and inserting a punch into the container thereby forcing the billet through the die. After the extrusion forging, the punch is raised to a prescribed level and held there and the container is subsequently raised. Since the undeformed part of the billet is attached fast to the container, the rising contai...

Transfer means for transferring a continuous elongate product, such as wire, bar or tubular products associated with a continuous extrusion machine, between two stations in the production line. Axial tensioning means 8, 10 each consisting of a pair of resiliently tyred wheels 12, 14 positioned to grip the elongate product 2 and driven by a low inertia, electric, motor induce an axial tension in the elongate product 2. The elongate product forms a curve 20 of catenary form between the axial tensi...

An extrusion run-out table for aluminum extrusions and the like has an extrusion support table for supporting extruded profiles as they are extruded from an extrusion press along an extrusion path and a conveyor for moving the extruded shapes from the extrusion support table to a cooling area and to a further processing area. The extrusion support table includes a set of elongated heat-resistant bars mounted perpendicular to the extrusion path, with the bars extending laterally of the extrusion ...

A conveying arrangement for supporting workmembers of an elongated nature which pass in a longitudinal direction through a work station and which emerge from the work station in such condition as to be capable of being damaged upon physical contact. The conveying arrangement consists of a guideway extending longitudinally beneath the emerging workmember and having upwardly directed air nozzles distributed longitudinally and laterally thereof and establishing an upwardly moving air body which eng...

An extrusion puller which comprises an upper jaw, a lower jaw, and means for mounting the upper and lower jaw relative to each other. The upper jaw comprises a plurality of jaw fingers with radially extending gripping teeth circumferentially spaced around the bottom portion of the tooth wherein the attack angle between teeth and the spacing angle between adjacent teeth is selected so that substantially full penetration of at least one of the gripping teeth into the workpiece is achieved without ...
