Portable pipe-bending minimachine able to be manually - or motor-controlled and including an engaging/automatic disengaging device.

摘要

Portable manually or motor-controlled pipe-bending minimachine which, in spite of its small size as compared with similar machines, is easier and handier to operate on site for the bending of pipes ranging 4 mm to 22 mm in diameter. The minimachine is provided with a reverse gear (53) and an intermediary device (50) built in the minimachine main body (11) which allows the engagement and automatic disengagement of the gear drive (40) transmitting rotary motion to the matrix-carrying shaft. Both the motor (90) and the manual control lever assembly (60) allowing alternate control of consecutive angular movements of matrix (16), can be easily and quickly mounted on the main body; and the countermatrix (24) is an interchangeable device to be mounted on a special support (20) allowing it to be appropriately positioned at the start of a bending operation.
