Abstract
A plastic pipe end forming tool to form both inside and outside bevels on a pipe end. An elongated body has a cavity constituting a cylindrical channel. A pair of opposed protrusions extend into the cylindrical channel to form a V-shaped space to receive the pipe end therein and to allow rotation of the pipe in the cylindrical channel and thereby form bevels on the pipe end.
Claims11
A plastic pipe end forming tool which comprises:
- an elongated body having a cavity constituting a cylindrical channel;
- and
- a pair of opposed stationary protrusions extending into said channel to form a V-shaped space to receive said pipe end and to allow rotation of said pipe in said channel and thereby form inside and outside bevels on said pipe end, without removing material from said pipe end.
A plastic pipe end forming tool which comprises:
- an elongated body having a cavity constituting a cylindrical channel;
- and
- a pair of opposed spherical knobs in said cavity to form a space to receive said pipe end and to allow rotation of said pipe in said channel and thereby form inside and outside bevels on said pipe end, without creating chips or shavings from the said pipe end.
A plastic pipe end forming tool which comprises:
- an elongated body having a pair of opposed cavities to constitute a pair of coaxial cylindrical channels;
- and
- a pair of opposed, stationery protrusions in each said cylindrical channel that form a pair of V-shaped spaces to receive said pipe end therein and to allow rotation of said pipe and thereby form inside and outside bevels on said pipe end.
A method to form a plastic pipe end, which method comprises:
- inserting a pipe having an end face perpendicular to its axis into a tool having a cavity in an elongated body forming a cylindrical channel;
- manually forcing said pipe end axially into said channel to engage a pair of opposed stationary protrusions extending into said channel to form a V-shaped space;
- and
- rotating said pipe while maintaining said axial force to form inside and outside bevels on said pipe end.
