Title: Actuating systems for hydraulically operated bending machines
IPC: B30B15/16
Filed: 1971-08-13
Abstract: 1347725 Press brakes AMADA CO Ltd 13 Aug 1971 [17 Aug 1970] 38028/71 Heading B3E A ram of a bending press is raised at an enhanced speed by supplying pressure fluid to the chamber a of a cylinder 5 from a pump 17 and from the chamber b of the cylinder, via circuit means 29, until increased resistance is met, e.g. at the start of a bending operation, whereupon the speed of the ram is reduced by operation of a valve means in the circuit means so that pressure fluid from the chamber b is fed to a reservoir 19. In operation the piston 11 is raised by pressurizing the chamber a while the fluid discharged from the chamber b passes via ducts 25, 26 to valve assembly 29, fluid being prevented from returning to the reservoir by a check valve 23. The discharge fluid from the chamber b passes through a chamber 43 of the assembly 29 to a duct 21 where it joins the pressure fluid from the pump. When the ram meets a workpiece the pressure in chamber a is raised until, at a predetermined value, the fluid is conveyed into an oil port 61 of the assembly 29. This causes a piston 49 to move to the left as seen in Fig. 3, against the resistance of a spring 55 and establishes an hydraulic connection between duct 26 and a duct 33. The discharge fluid from chamber b therefore passes along duct 33 to the reservoir. Upon completion of the bending operation a valve 37 is actuated to close duct 21, thus causing the fluid in chamber a to flow into the reservoir due to the piston being lowered by the weight of the ram, fluid being sucked into chamber b via duct 25 and check valve 23.

Exemplified is the formation of hexamethylene-diamine by condensing alkyl chloride with propylene, followed by hydrobromination of the resulting 1,5-hexadiene and subsequent ammonolysis of the bromo derivative. The hydrobromination stage may also yield the by-product 6-bromohexene-1.

Each spring 14 bears at one end against a body 15 and at the other end against a yoke 13 having a spherical surface which co-operates with a complementary surface on a washer 12 separated from a flange 9 on the piston by thrust washers 11. Pins 17 fixed to the body 15 pass through the springs 14 and apertures 18 in the yoke to prevent the latter from turning. During each suction stroke of the piston the pumping chamber 30 is filled with fuel from a space 26 through passages 27, 28 and whichever of grooves 29 in the piston is registered with the passage 28. Fuel is delivered via a delivery valve 23, passages 31, 32 and grooves 33, 34 in the piston, the groove 34 registering in turn with passages 35 each leading to an outlet 36. A sleeve valve 43 surrounds the piston in the space between the springs 14 and controls a spill passage 38 from the pumping chamber 30.

A water-tube steam or hot-water boiler comprises a number of generating cells each consisting of a vertical casing within which is disposed an array of vertical water tubes defining an inner combustion chamber and an outer gas flow chamber and a burner firing into the combustion chamber whence hot gases flow into and through the outer chamber to heat water within the tubes, hot water or a water-steam mixture discharging from each cell into a common drum whence downcomers convey water to the lower ends of the tubes so that convection circulation of the working medium is established. Fig. 2 shows one of the cells 11 connected to the common drum 35. The cell has a casing 12 terminating in a lower inlet header 17 connected to the drum by a downcomer 27 and an upper annular outlet header 19 connected to the drum by risers 30. A ring of vertical tubes 13 connects the headers 17, 19, the tubes being joined laterally by welding except at their lower ends where they are offset to provide a gas flow path between a combustion chamber 14 within the tube ring and an annular gas flow passage 15 on the outside thereof. The combustion chamber is downwardly fired by a burner 41 projecting through the annular header 19. Gases flowing upwardly in the passage 15 discharge therefrom into a duct 44. In a modification, Fig. 4 (not shown), the inner chamber is upwardly fired and the casing wall is lined with vertical water tubes, a bottom gas offtake being provided.
