[0007] On the other hand, although the interlocking tube with a circular cross section is wound with a core with a circular cross section, it cannot be hooked due to its circular shape, and springback (spring back) will occur when the tube is wound. back), the tube does not hold coils in a predetermined shape well, and in relation to springback as opposed to thrust, may result in rotational looseness
Also, interlocking tubes with an oval cross section have the same problem

Embodiment Construction
[0043] Hereinafter, embodiments of the present invention will be described with reference to the drawings. figure 1 It is a plan view for explaining the schematic structure of this invention, and the operation of each device is performed based on the control device 25 which summarizes and calculates the operation of each device as shown in the figure. Likewise, as system actions such as Figure 8 What is shown is based on the main calculation-control unit 101 of the system body 100 . No matter which one, the equipment operation time is set according to the average production time required for each product, so based on the product diameter [mm], pitch [mm], product length [mm], set time (set production cycle) Time is the processing target time of each product) to calculate and set.
[0044] That is, to obtain a semi-finished interlocking pipe 10 used as an exhaust pipe of an automobile or the like, a long flat metal strip 10a having a certain width is formed into a curved me...

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.
Description
technical field [0001] The present invention relates to a manufacturing method of interlocking pipes and a manufacturing device thereof. It is an automatic device for setting the operating time of equipment according to the average production time required for each product when manufacturing pipes with a circular, polygonal or elliptical section. A forming device or an automatic forming system can form the above-mentioned tube easily and with high precision without loosening, has excellent processability during cutting, etc., and is excellent in improving the working efficiency of the production device itself. Background technique [0002] In the past, as vehicle exhaust pipes such as automobiles, such as Figure 9 Flexible tubing as shown is known. That is, such a flexible pipe 1 is a member for preventing vibrations on the engine side from being transmitted to downstream parts and the like. Therefore, the interlocking type flexible pipe 2 (hereinafter referred to as inter...
