The pipe rounding machine is a widely used cold forming machine.
According to the principle of three-point circle, the relative
position change and rotary motion of the workpiece are used to make
the workpiece undergo continuous plastic deformation to obtain a
predetermined shape of the workpiece. The product is widely used in
sub-boiler, shipbuilding, petroleum, woodworking, metal structures
and other machinery manufacturing industries.
In foreign countries generally divided by the work roll
configuration. In China, hybrid classification is generally carried
out based on the number of work rolls and adjustments, and is
generally divided into three-axis series, four-axis series, and
seven-axis series.
It is mainly suitable for curving, large-radius bending, rolling
and other modeling of various pipe fittings, and can machine
different pipe fittings by changing mold specifications and shapes,
roll different curvatures and radiuses by adjusting mold dimensions
and the centre distance of rollers, and continuously roll many
circles according to the length of pipe fittings.
