Abstract
1,190,868. Hydraulic presses. NOVA MACHINERY PTY. Ltd. 7 Nov., 1968 [15 Nov., 1967], No. 52852/68. Heading B5F. A levelling control for a press having a platen 11 operated by a pair of hydraulic rams 12, 13, comprises an elongated torsion member 14 having one end attached to a fixed point of the press and the other end operatively connected to one or more hydraulic valves 19 arranged to control the supply of hydraulic fluid to one or both of the rams 12, 13 in response to twisting of the torsion member 14. The member 14 may be a torque tube having an arm (15), Fig. 2 (not shown) fixed thereto at one end. The arm (15) is pivotally connected to a link member (17) itself pivoted to a part of the press frame. The other end of the tube 14 has an arm 16 fixed thereto and pivotally connected to a link member 18. Limit switches (22), Fig. 3 (not shown) cut off the oil supply to the leading ram if the press overrides the levelling control. Further limit switches 23 ensure that the platen 11 is truly horizontal at the point of reversal at the bottom of its stroke. The switches 23 are fixed to the platen 11 and operated by stops 27 slidably mounted on shafts 25 fixed to the lower press table 24. The stops 27 are adjustable simultaneously by a hand wheel 30 through a shaft 29 and gear boxes 28.
