  • Patent number: 5907968
    Abstract: The invention relates to a device for the stepwise transverse transportation of sections, in particular groups of sections, from a longitudinal conveyor at the delivery end of a metal extrusion press to a first (8) and optionally a further (9) cooling station as far as a stretcher-leveller, in which each group of sections is gripped between clamps (I, II) at the ends of the sections during the said transverse transportation, in addition the clamps (I, II) accompanying a group of sections over one step with the clamps accompanying the next step and finally the clamps (12) of the stretcher-leveller arranged at the outside position ?are! arranged alternately offset in the longitudinal direction of the sections at the distance of the depth of a clamping jaw, and the clamps (I, II) for one step remain closed until the clamps for a following step or the clamps (12) of the stretcher-leveller are closed, and in which the clamps which are open laterally in the transverse conveying direction are supported by vertical c

  • Patent number: 5802905
    Abstract: The object of the invention is to apply an appropriate temperature profile to a bloc to be extruded, at which the extrusion process may be optimized For that purpose, the metal blocks (10a) to be extruded are heated (furnace 2) up to an appropriate extrusion temperature for that metal, are stored at that temperature (holding chamber 3) and are chilled (chamber 5) according to regulation areas (18) in synchronism with the extrusion cycle. Regulation in the areas (18) is carried out by influencing the amount and/or temperature of the coolant, and/or cooling duration, so that an axial and radial temperature distribution is obtained at the block.

  • Patent number: 4426865
    Abstract: In a metal extrusion press, extrusion tools such as dies, mandrels, and closure members for billet receivers, are lubricated by bringing into contact with these tools, while the tools are hot, candles of lubricant material which melt on contact with the tools. The candles are moved into and out of engagement with the tools by a movable support operating automatically in the press cycle.

  • Patent number: 4334421
    Abstract: The discharge roll table comprises a plurality of rollers for receiving extruded bar or tube. A top cover extending along the table above the rollers is of substantially inverted V-shape cross section and is divided along the top edge into two half covers pivotable to the left and right of the table respectively. Each half cover is divided into cover sections aligned end to end and is connected at an angle to lifting devices arranged between the rollers. Thus the extruded product may be lifted to the left or right of the table, which may be substantially the same length as the extruded product.
