大小に直接影響し、これら精度の向上には現状では限界
があるからである。Conventionally, spinning molding is generally used to manufacture thin-walled tubular bodies.In this method, a mantle is inserted into a thick cylindrical workpiece and rotated integrally with the workpiece, and a roller is pressed against the mantle so as to align it with the axis of rotation. This is a method of forming by collecting and moving it. Therefore, although this method is suitable for manufacturing long tubes, it is said to be difficult to obtain highly accurate tubes without uneven wall thickness. This is because the eccentricity of the mandrel, the rotational runout of the device, the non-uniformity of the material, etc. directly affect the size of uneven thickness, and there is currently a limit to the improvement of these precisions.
本発明は上述の事情に鑑みてなされたもので、ローラの

な管体を得るスピニング成形方法である。The present invention has been made in view of the above-mentioned circumstances, and is a spinning forming method that corrects uneven thickness by controlling the rotational torque of the rollers and obtains a highly accurate tube body.

are attached and rotated together around the axis (3), and the roller (4) is moved toward the axis (3) in the direction of the arrow (6) while being rotated by the motor (5). As a result, the wall thickness t1 is formed to a smaller wall thickness [2], and a thin tube body (7) is obtained.

制御するトルク制御装置αSとからなっている。The above is similar to the conventional spinning molding apparatus, but the apparatus used in this embodiment is equipped with a control device α. This is a part that estimates the uneven thickness of the butter 7 from the pattern of the processing force applied to the roller (4) K, and controls the torque of the motor (5) based on this. That is, attached to the axis α of the roller (4) is a detector α consisting of nine load cells, an arithmetic device α which inputs the output from the detector I and performs a predetermined calculation,
A torque control device αS receives the output from the calculation device αS and controls the torque of the motor (5).

大きさを連ねると曲!IAのようなパターンとなる。Next, this embodiment will be described along with its operation. The workpiece (2) is attached to the mandrel (1) and rotated, and the roller (4) is brought into close contact with the workpiece (2) from one end while being rotated by the motor (5). As a result, the roller (4) starts forming, and the processing force applied to the roller (4) is detected by the load cell I. The pattern detected by this method is, for example, as shown in Fig. 8g2, when the cross section of the workpiece point (2) is divided into n equal parts and the magnitude of the machining force at each division is connected. It becomes a pattern like IA.

パターンを変えて偏肉のないように成形する。Here, calculations are performed according to a preset calculation program, and the output is input to the torque control device (l!9).Here, the torque of the motor (5) is controlled based on this human power to lower the roller (4). Adjust the ratio and change the pattern of the 111 line A to mold so that there is no uneven thickness.
