Abstract

Workpieces are mounted for hardening by heat treatment of an expanding mandrel (1) with internal or external taper made up of individual segments in the form of lamellae (4). The lamellae are pref. displaceable transverse to the axis of the taper and are held in guides (3). They may be subjected to preloading by the action of a spring (7), which forms a ring connecting them. The end faces of the lamellae form a supporting surface for the workpiece (6).

Description

-nano 1 0.1.0. 521 963 .' 2 De tidigare använda segmenten är uppdelade i separata lameller 4, som är anordnade så att de kan fórskj utas vinkelrätt mot konaxeln 5. Vid en anpassning till olika diameter eller omkrets undviks således att det uppstår ett alltför stort mellanrum mellan de kraflzbelastande lamellerna. Med hjälp av konan 2 kan lamellerna 4 ställas in på den önskade diametern. -nano 1 0.1.0. 521 963. ' The previously used segments are divided into separate slats 4, which are arranged so that they can be displaced perpendicular to the cone shaft 5. When adapting to different diameters or circumferences, an excessive gap between the load-bearing slats is thus avoided. With the help of the cone 2, the slats 4 can be adjusted to the desired diameter.

Därigenom kan ett enda verktyg användas till flera olika diametrar.In this way, a single tool can be used for your different diameters.

Uppfinningens fördel är således den stora breddningen av det område av diametrar for arbetsstyckena som kan bearbetas. Vid användning av segment av gängse slag täcks normalt ett diameterintervall av 1/10 mm. Med uppfinningen täcks ett intervall av mer än 1 cm.The advantage of the invention is thus the large widening of the range of diameters of the workpieces that can be machined. When using segments of the usual type, a diameter range of 1/10 mm is normally covered. The invention covers an interval of more than 1 cm.

Lamellerna 4 belastas av en fjäder 7. Med verktyget placerat så att konaxeln 5 är verti- kal blir fiädern 7 horisontell. Fjädern 7 går ringforrnigt genom styrhål 8 i lainellerna 4.The slats 4 are loaded by a spring 7. With the tool positioned so that the conical shaft 5 is vertical, the spring 7 becomes horizontal. The spring 7 passes annularly through guide holes 8 in the liners 4.

Expanderdornen enligt uppfinningen for härdningsanordxiingar har således stor förmåga att anpassa sig till olika diametrar i arbetsstycken.The expander mandrel according to the invention for hardening devices thus has a great ability to adapt to different diameters in workpieces.
