Patent number: 4532787Abstract: A portable pipe-bending apparatus is electromechanically controlled to bend a pipe up to an angle of 180.degree. without providing any undesirable uneven stretching, also when the pipe is formed of a material which is particularly sensitive to stretching stresses. A driving motor-reducer is used which comprises a motor of low power and very high speed and a reduction gear with a very high reduction so as to rotate a semipulley main bending member, or matrix, having a peripheral semicircular groove. A second bending member, or countermatrix, faces the matrix and is supported by a supporting member which may be moved away or approached to the matrix at a distance in accordance with the diameter of the pipe to be bent.Type: GrantFiled: March 9, 1982Date of Patent: August 6, 1985Assignee: C.M.L.

Patent number: 4232542Abstract: Portable manually-controlled hydraulic pipe-bending apparatus comprises a coupling head and reversible bending members to reverse the bending direction of a pipe relative to the apparatus. The coupling head has thereon two parallel pins for supporting the fixed bending member, and a piston stem that moves toward and away from the pins to support the movable member. The two arcuate bending members are provided with recesses to receive either the pins or the piston stem, thereby adapting them to reversible mounting for bending a tube in either of two opposite directions.Type: GrantFiled: March 29, 1979Date of Patent: November 11, 1980Assignee: C.M.L.

Patent number: 4055069Abstract: A pipe bending device is manually operated to pump hydraulic fluid, under the influence of a first reciprocating piston, to extend a second reciprocating piston to bend the pipe. The hydraulic fluid is urged on the pressure stroke of the first piston past a first ball valve and further hydraulic fluid is drawn by the first piston past a second ball valve upon the suction stroke of the first piston. A manually operated lever operates the first piston by swinging movement of the lever through a predetermined angle. A third piston is contacted by that same lever upon further swinging movement of the handle beyond that predetermined angle, in order to open a return passageway for the hydraulic fluid to release the device. The return passageway can be controlled by a third ball valve, or by pins that open both of the first two ball valves.Type: GrantFiled: March 31, 1976Date of Patent: October 25, 1977Inventors: Alessandro Caporusso, Mario Caporusso
