METHOD AND APPARATUS FOR MANUFACTURING INTERLOCKING PIPE

摘要

The present invention provides a method and an apparatus for manufacturing an interlocking pipe obtained by easily and precisely shaping a pipe with a circular cross section or with the edges of the cross section nearly forming a circle in a non-loose manner, so as to provide excellent machining performance when the interlocking pipe is cut off and provide excellent operation efficiency for the apparatus itself. A metal band plate is helically wound onto a core member with a circular cross section or with the edges of the cross section nearly forming a circle. Clamping device is freely assembled at a front end of the code member in a detachable and switchable manner, and synchronously rotate in accordance with instructions from a main computing-controlling member, so as to prevent the metal band plate from being loosened, thereby to manufacture the interlocking pipe efficiently.

主权项

1. A method for manufacturing an interlocking pipe, the interlocking pipe is shaped in accordance with instructions from a main computing-controlling member by bending an elongate metal band plate with a certain width into an S-shaped cross section and helically winding onto a winding core member in a way that adjacent end portions thereof are engaged with each other, wherein
the interlocking pipe is of a shape with a circular cross section or with the edges of the cross section nearly forming a circle, and the method employs a clamping device, which is configured to synchronously rotate in such a manner that the metal band plate wound in accordance with the instructions from the main computing-controlling member cannot be loosened, and to freely clamp the metal band plate in a loose or tight manner.
