摘要： A guiding device (2) includes a base (21), a cover (23) and a sidewall (22) cooperatively defining an annular space therein and a passage therethrough. An air inlet (221) is defined in the sidewall communicating with the space for an airflow flowing into the space. A plurality of guiding plates (24) are arranged in the space around the passage. An air outlet (29) is defined between two neighboring guiding plates for the airflow flowing out the space into the passage. The airflow is distributed into a plurality of even streams by the guiding plates. An atomizer (4) is connected with the space via the air inlet. The atomizer produces a high-pressured water vapor which is taken by the airflow to cool an aluminum profile produced by an extrusions press (6) and moving through the passage.

摘要： 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. This temperature distribution allows isothermic extrusion at an optimum extrusion speed, taking into account the heat conductivity of the metal, the heat flow to the remaining block, to the block support and to the extrusion tools (die, matrix), as well as the increase in temperature of the block due to the heat produced forming and by friction of the block against its support, when such friction is present, i.e., in the case of direct extrusion.

摘要： A core body (60) is disposed in a feed passage (40) in rear of an extrusion die (5), with the passage being provided to transport an extrusile material. One or more annular passageways (63) are formed between the outer periphery of the core body and the inner periphery of the feed passage, so that helical edges (50a, 55a) protrude into the annular passageways. As the helical edges (50a, 55a) are driven to rotate, a strong thrust is applied to the extrusile material (M) within the feed passage (40) towards the extrusion die (5), so that the extrusion pressure is raised to improve the extrudability of various raw materials.

摘要： Apparatus for continuously extruding material includes a moving member and a stationary member forming a passageway therebetween for frictional feeding of the material to be extruded under pressure into the passageway. An abutment in the passageway forms a barrier to the material being fed therein, whereby the forces on the material heat it and cause it to yield. The heated material flows into an extrusion chamber adjacent to the abutment and is extruded from a die in a wall of the chamber. A cooling system provides first and second phases of quenching the extruded product separated by an interval of self-annealing to limit the surface grain size and the hardness of the extruded product. The product is subjected to the first phase of quenching immediately as it exists the die, to maintain the temperature of the extruded product at a desired fixed level at a selected point along the flow path of the extruded product downstream of the die.
