Definitions
- the invention relates to a device for hardening of metallic goods, having a roller furnace for Austenitizing the good and a hardness press for that yet hot good.
- They are devices for tempering metallic goods, especially known for hardening tool steels a furnace for austenitizing the material, a hardening press for the still hot goods and a tempering furnace for the purpose Have the hardness and structure of the goods.
- a device for heat treatment is known: "Heat treatment of structural and tool steels", 3rd ed., Editor Hans Benninghoff, Sigma textbook series, 1978, p. 451 to 444, Ruhfuß, "heat treatment of ferrous materials", Verlag Stahl Eisen mbH, 1958, pp. 380 to 383 and 386.
- the hardness press from a A plurality of pairs of press plates working together is formed, which at the end of the roller furnace next to the Roller conveyor are arranged one behind the other and that Bracket parts for the cross bracing of the between the goods located between the plates in Hardness position can be inserted, workpieces are free from distortion can be produced.
- the figure shows the exit of a roller furnace, with 10 the individual roles are designated and 11 the Indicates the conveying direction of the roller conveyor. Usually would the individual workpieces are intended to be on the left front Leave the roller oven in the direction of arrow 11.
- a push part 12 is provided which with the help of a working cylinder in the 16 designated directions can move.
- This thrust part 12 serves first of all to remove the workpiece from the roller conveyor to promote the lower press plate 13. It is can be seen that several such push parts 12th one after the other in the direction of movement of the roller conveyor 11 can be arranged.
- a corresponding stop 16 is located to the other side of the workpiece 20 above the lower press plate 13. In the embodiment shown the invention of the stop 16 via a stamp 14 in Direction of the arrows 15 pivoted. Also the Stop 16 has a thickness that is less than that too processing workpiece 20.
- the hardening procedure is as follows:
- the workpiece 20 is from the roller conveyor 10 on the Thrust member 12 brought into the position shown in the figure.
- the Stop 16 is also in the position shown and ensures that the workpiece 20 does not have a intended position can be moved to the right.
- the upper press plate not shown, is lowered and exercises together with the lower press plate 13 Pressure on the workpiece 20.
- the stop parts 16 and 21 are fixed via working cylinders pressed against the workpiece 20, so that this no Can perform tensioning movements.
- the stamp 14 with the stop part 16th pivoted away so that the workpiece 20, for example in Direction to the right can be seen.
