Abstract

A bending apparatus for metal pipe and tubing which includes an upright spindle assembly; a lower section mounted on the spindle assembly for rotational movement around the spindle, the lower section can be selectively moved around and engaged with the spindle assembly; an upper section which is rotatably mounted on the spindle assembly and removably connected to the lower section, the upper section includes a removable shoe bender; and a radius die positioned at the top of the spindle assembly and in pipe or tube engaging alignment with the shoe bender. The bending apparatus can be disassembled, and moved to a different work site, and reassembled by one person. The bending apparatus can bend pipe or tubing of one-half inch to two inch diameter and larger.

Claims

1. A pipe and tubing bender which comprises:

an upright, free standing, spindle assembly having a vertical axis, said spindle assembly comprising a lower part and an upper part, said upper part, at its lower end, having sleeve means which releasably fits over said lower part and is concentric therewith, said sleeve means being rotatable around said lower part;

a lower section which is removably mounted on said spindle assembly and which is rotatably movable and selectively adjustable around the vertical axis of the spindle assembly, said lower section including means for releasably engaging said spindle assembly;

an upper section which is removably mounted on said spindle assembly, said upper section being rotatably movable around the vertical axis of the spindle assembly, said upper section being removably and pivotally connected to said lower section, said upper section having shoe bender means thereon which is adjustable for engaging a pipe or tube for bending, said upper section having means to apply pressure to and cause said shoe bender means to move and bend the pipe or tube;

said upper part of the spindle assembly having means near its lower end for permitting said lower section to be selectively engaged and locked to said upper part; and

a radius die releasably mounted on the upper end of said spindle assembly with said shoe bender, said die having means affixed thereto for releasably receiving and holding a pipe or tube.

2. The bender according to claim 1 wherein the upper end of said upper part of the spindle assembly is substantially square to cooperatively and slidably receive said radius die to hold it in a fixed position.

3. A pipe and tubing bender comprising:

a base member;

an upright spindle assembly having an upper part and a lower part having a vertical axis, said lower part being attached to said base member, said upper part being slidably and concentrically positioned around and over said lower part, said upper part being rotatable around the vertical axis of said lower part and having means for releasably securing said upper part to said lower part, said upper part having a flange near the bottom thereof, said flange having a plurality of notches around its periphery;

a lower section member having an inner end and an outer end, said inner end being slidably mounted on said upper part of the spindle assembly for rotational movement therearound, said lower section member having means for selectively and releasably engaging any notch in said flange to hold the lower section member in a fixed position;

an upper section member having an inner end and an outer end, said inner end being slidably mounted on said upper part for rotational movement therearound, the outer end of said upper section member being releasably and pivotally connected to the outer end of said lower section member, said upper section member having a bending shoe releasably mounted thereon and means for engaging and bending a pipe or tube; and

a radius die member releasably fixed on the upper part of the spindle assembly and in pipe or tube engaging alignment with said bending shoe of the upper section member, said die member having pipe or tube holding means releasably attached thereto.
