Abstract

814,036. Broaching. WEATHERLEY OILGEAR Ltd. Jan. 6, 1958 [Jan. 4, 1957], No. 484/57. Class 83 (3). A broaching-machine comprises a tool-slide 1 reciprocated by a pair of pinions 8, 9 engaging at least one rack 6, 7 on the slide, and separate, reversible hydraulic motors 14, 15 for rotating the pinions. The reversible radial piston hydraulic motors 14, 15 are supplied with fluid by a variable-delivery radial piston pump 16 through a controlvalve assembly 18. The valves can be set so that both hydraulic motors take equal load during cutting and idle strokes, or either motor can be used for broaching and return with the other idling. Alternatively, one motor may drive against the resistance of the other. Such resistance may be varied during a stroke by switches operating solenoids &c.
