Patent number: 10245650Abstract: A chucking device for a tool includes a tool receiving element; a collet for clamping the tool, the collet being inserted in an opening in the tool receiving element; a clamping nut for axially displacing the collet in relation to the tool receiving element; and a pressure piece which is arranged between the clamping nut and the collet and is rotatably mounted in relation to the clamping nut, by means of which piece the collet can be axially displaced in relation to the tool receiving element by the clamping nut. To permit a tool shank to be securely clamped in and released from the collet, even under extremely high clamping forces, the pressure piece has coupling elements for a torsion-proof connection to corresponding mating elements of the tool receiving element.Type: GrantFiled: September 8, 2014Date of Patent: April 2, 2019Assignee: Haimer GmbHInventors: Franz Haimer, Wolfgang Kügle

Patent number: 10165629Abstract: The induction coil unit for heating a component which is rotationally symmetrical relative to an axis, includes a plurality of coils arranged about the axis of the tool holder, with pole elements, which are movable radially with respect to the axis, of which pole elements each one consists of includes a stack of pole rods that can be moved relative to one another. A yoke ring connects the pole elements, which, when the coils are excited by alternating current in the tool holder, produce a magnetic flux running in the peripheral direction to inductively heat the tool holder. The pole rods of each pole element can be moved jointly by means of pinion rollers, wherein, however, slide couplings or the like are provided in the drive force transmission path between the individual pole rods so that the pole elements can adapt to different contours of the tool holder.Type: GrantFiled: September 11, 2012Date of Patent: December 25, 2018Assignee: HAIMER GMBHInventors: Franz Haimer, Wolfgang Kugle

Patent number: 9878376Abstract: The invention provides a clamping system (1) for a rotary tool (70), for example a milling cutter or drill. The clamping system (1) includes a base element (10), a collet (30) and a clamping nut (50), said clamping nut (50) friction-locking the rotary tool (70) within the base element (10) with the collet (30). In order to avoid a relative rotation of the base element (10) and the collet (30), the clamping system (1) has a form locking anti-twist protection which blocks a rotation of the collet (30) relative to the base element (10).Type: GrantFiled: August 29, 2012Date of Patent: January 30, 2018Assignee: Haimer GmbHInventors: Franz Haimer, Wolfgang Kügle

Patent number: 8821085Abstract: The invention relates to a tool holder (1) for clamping tools by shrink fit. The tool holder, due to its specific shaping in the area of the shrink-fit head (6) and the shrink-fit base (5) of the tool holder, is less prone to oscillate than known tool holders, therefore allowing inter alia higher speeds so that the cutting capacity, determined by the speed of the tool, the tool feed and the cutting depth of the tool, can be increased and the machine running times required to produce a workpiece can be reduced. The tool holder (1) of the present invention allows to produce and machine workpieces in a substantially more efficient and economical manner.Type: GrantFiled: September 7, 2006Date of Patent: September 2, 2014Assignee: Haimer GmbHInventors: Franz Haimer, Wolfgang Kugle
