Abstract

24,574. Klarwasser, A. Oct. 22. Angular bending; coiling; bending dies and formers.-In a machine for bending pipes or profile pieces of the type in which the mandrel is either fixed and the bender rotatable or the mandrel is rotated and the bender stationary, a turntable mounted in a frame carries a bender round a stationary mandrel, the bender being replaced when desired by a mandrel which is rotated in conjunction with a fixed bender In the form shown in Fig. 1, the pipe is clamped to a fixed mandrel f mounted on one of the square portions of a shaft d and bent by a roller e which is radially adjustable in the turntable a rotated by worm gear s. The mandrel and roller e are stepped and have grooves of different widths to suit work of different sizes. In the form shown in Fig. 2, for coiling pipes or bending to larger radii, the spindle c of the roller e, Fig. 1, is passed through a hole in the mandrel f<1>, which is rotated against a roller i mounted on the frame g; the roller is capable of sliding on its spindle h. The mandrel rotates on a guide-piece l, which is fixed on the square shaft d. The worm s may be rotated by a hand crank or ratchet gear. In coiling pipes, a mandrel having three or four turns is used, being reversely rotated between each coiling operation to allow the coil to unscrew from the mandrel.
