Abstract

1,207,757. Grinding. MASCHINENFABRIK KARL HACK K.G. 13 Dec., 1968 [15 Dec., 1967], No. 59403/68. Heading B3D. A machine for grinding spring ends comprises two coaxial grinding wheels 6, 7 mounted on a machine frame 1, one above the other and at least one of which is axially adjustable, and two rotatably mounted transporting plates 13, 14, Fig. 3, arranged to receive springs and hold them for grinding, rotational movement of each transporting plate when in the working area of the grinding wheels carrying the springs between the wheels, the plates being mounted on separate carriages 9a, 9b, the carriages being detachably connected to one another and movable together on the machine frame in a straight line parallel to the planes of the grinding wheels, between two end positions in each of which one transporting plate lies in a working position between the two grinding wheels, and the other transporting plate lies in a charge and discharge position. In one embodiment the plates 13, 14 which comprise pairs of discs 22, 23, Fig. 2, with apertures 24 for receiving springs 25, are mounted side by side on the carriages which are movable along a dove-tail section guide 10 of the frame 1 by an hydraulic cylinder device 11 or mechanically or manually. The upper surfaces 12 of the carriages are coplanar with the upper surface of the wheel 7 and with a table 20 which retains the springs in the apertures 24. Apertures 27, 28, Fig. 3, in the carriages, which are closable by flaps, allow the springs to be discharged from the plates 13, 14. The plates 13, 14 may be rotated at different speeds depending on their positions. A carriage member 9 is composed of the carriages 9a, 9b each of which carries a plate 13, 14 respectively and the drive therefor. The carriages are separable to permit removal of the grinding wheels between them. In a second embodiment, the plates 13, 14 are suspended from the carriages which travel on a guide located above the grinding wheels.
