The welded pipe mould is a metal component for the production of welded pipe, which is set on the roll shaft of the pipe making machine.Then how is the welded pipe mould fixed on the pipe making machine roller, it is necessary to look at the drilling method of the welded pipe mould.

The horizontal shaft of the pipe making machine has an elongated card key. When the pipe making mold needs to drill a hole, the method of wire-electrode cutting or punching is adopted to leave the fixed position of the card key.Because the horizontal axis can be driven by the motor, so the tube mold does not need to drill the hole when the bearing hole.

The vertical shaft of the pipe making machine is basically fixed, so the welded pipe mould installed on the vertical shaft needs to install bearings, so the vertical shaft welded pipe mould needs to leave holes through the vertical shaft when drilling holes.At both ends of the welded pipe mould, the position required for shaft mounting bearings should be set aside.

It is necessary to pay attention to the concentricity and accuracy of the hole diameter in the welded pipe mould.Only the small error and high accuracy of the processing process produced out of the pipe mold is a good mold, also can produce beautiful pipe.Because the error is big, and the roller shaft, bearing installation are loose, will produce the gap shake.
