MANUFACTURING METHOD FOR INTERLOCKED TUBE AND MANUFACTURING DEVICE THEREFOR

摘要

An automatic formation device or an automatic formation system sets an equipment operation time from a required manufacturing time per product during the manufacturing of tubes having a round, polygonal, or oblong cross-section, wherein values are calculated from a product diameter (D), and a pitch (P), a product length (L) and a preset time (T) of a metal band plate to be wound, operations of respective components are controlled on the basis of the calculated values while the respective values are being controlled, and the metal band plate is held by a chuck that is disposed on the tip side of a winding core member and rotates in a synchronized manner so as to prevent loosening of the wound metal band plate by tightening/untightening the metal band plate as needed. Also, a rotation speed correction function for a motor system is added.

1. A method for manufacturing an interlocked tube, which is of a round, polygonal or oblong cross-section, and shaped by bending an elongate metal band plate with a certain width into an S-shaped cross section and helically winding the metal band plate onto a winding core member in such a way that two adjacent end portions thereof are engaged with each other by means of members for treating the metal band plate successively in accordance with instructions from a main computing-controlling member, wherein
the method employs following members: the main computing-controlling member configured to control actions of each member based on values calculated in accordance with product diameter (D), pitch (P), product length (L) and setting time (T) of the wound metal band plate, and to aggregate the values; a motor controlling member configured to perform treatment in accordance with instructions from the main computing-controlling member, and to perform three-axis synchronous control on a forming members system spindle motor III, a material conveying system roller motor II and a clamping device system cover motor V with the forming members system spindle motor III as a reference axis via a pulse instruction from the main computing-controlling member; and a clamping device configured to synchronously rotate in such a manner that the wound metal band cannot be loosened, and to clamp the metal band plate in a freely loosen or freely tighten manner.
