Title: Improvements in metal pipe bending machines
Inventor: KING CECIL NORMAN
IPC: B21D7/06
Filed: 1953-07-23
Abstract: 798,742. Angular bending. EXACTOR, Ltd. Sept. 14, 1954 [July 23, 1953], No. 20515/53. Class 83 (4). A pipe-bending machine comprises a double-acting ram and cylinder arrangement, a pump to supply liquid under pressure thereto from a reservoir incorporated in the machine, and a manually operable control valve of the shuttle type by which the output of the pump can be caused to move the pressureapplying head of the machine on its power stroke and on its return stroke. A pipe bender of the type in which a pipe is bent between two spaced rollers by a former carried by a ram 3 has the ram reciprocated in a cylinder 2 by liquid pressure means. Liquid from a reservoir 16 on the cylinder 2 is pumped, by a plunger 15 reciprocated by a lever 21, past a non-return valve 19 and through a passage 18 to a manually actuated control valve 14..In the position of the valve shown in Fig. 3, pressure liquid passes from the valve through passages 9, 91 and 8 to a space 7 in the cylinder 2 to one side of a cap 4 secured to the end of the ram 3. Pressure liquid also passes from the valve through passages 13, 12 and an annular space 11 surrounding the ram to the other side of the cap 4. As. the pressure liquid contacts only an annular packing ring 6 on this side of the cap 4 pressure on the other side, acting on a greater area, will urge the ram 3 to the right, Fig. 1, to perform the bending stroke. When the valve 14 is moved down from the position of Fig. 3, the passage 9, and thus the space 7, is connected to exhaust to the reservoir 16 but the passage 13 and thus the annular space 11 remains connected to the pressure side of the pump 15, so that when the pump is now actuated the ram 3 is moved back. The control valve may be . arranged to connect both sides of the ram head or cap alternately to pressure and exhaust.
