摘要： A forging die heating or preheating apparatus comprises a burner head comprising a plurality of flame ports. The burner head is oriented to compliment an orientation of at least a region of a forging surface of a forging die and is configured to receive and combust a supply of an oxidizing gas and a supply of a fuel and produce flames at the flame ports. The plurality of flame ports are configured to impinge the flames onto the forging surface of the forging die to substantially uniformly heat at least the region of the forging surface of the forging die.

摘要： A method that includes: providing a blank; heating the blank; forging the heated blank to form a forged gear having a plurality of spiral bevel gear teeth; machining the forged gear to a predetermined thickness while locating off of the plurality of gear teeth to form a green machined forged gear; rotationally and axially engaging a die to the gear teeth of the green machined forged gear to induce plastic flow in the gear teeth to form an intermediate gear in which the plurality of gear teeth conform to a predetermined tooth form; heat-treating the intermediate gear to form a hardened intermediate gear; and lapping the plurality of gear teeth of the hardened intermediate gear with a spiral bevel pinion gear; wherein the plurality of gear teeth are not machined in a chip-producing machining operation before the plurality of gear teeth are lapped.

摘要： A forging die device is provided with an upper die 10 and a lower die 20. At least one die 10 (20) of the upper die 10 and the lower die 20 has a die holder 12 (22) which surrounds the outer periphery of the die 10 (20) and holds the die 10 (20). The die holder 12 (22) is configured to bear the radial tensile stress (tensile force) received by the die 10 (20) during forging. By this means, the die 10 (20) can be miniaturized.

摘要： The invention relates to a heat treatment device (1), optionally with a downstream hot-forming device (15), comprising at least a first heat station (12), a second downstream heat station (12), optionally one or more further downstream heat station(s) (14), a transfer device for supplying and/or discharging the workpieces (11) to and/or from the heat stations (12-14), and a control device for operating the transfer device and/or the heat stations (12-14). The first heat station (12) is designed in such a manner that the workpiece(s) (11) received therein is/are or can be heated to a predefined first temperature within a predetermined first dwell time. The at least second heat station (13) comprises more workpiece receiving spaces (13a) than the at least first heat station (12) and is designed in such a manner that the workpieces (11) received therein can be in each case heated within a certain second dwell time, which is greater than the first dwell time in the first heat station (12), to a predefined second temperature and/or can be constantly maintained at said predefined second temperature, wherein the predefined second temperature in the second heat station (13) is approximately equal to or higher than the predefined first temperature in the first heat station (12). The invention further relates to a heat treatment method.
