摘要： PURPOSE:To measure dimensions and the shape of a material to be measured without contacting, by moving an industrial television camera on a measuring plane, which is at a known specified angle to the face to be measured of this material, while picking up the image of the region including the circumferential line of this face to be measured in the direction vertical to this face to be measured by the industrial television camera. CONSTITUTION:In case of measurement for an outside circumferential line 8 on a face 7 to be measured which coincides with the end face of a hollow cylindrical forged material 5 and is vertical to an axis 6, an industrial television camera 10 is moved on a virtual measuring plane 9 which is at a known specified angle to the face 7. In measurement, the camera 10 is moved on the plane 9 along the line 8 so that an optical axis 11 of the camera 10 is vertical to the face 7 and intersects the line 8, and a projection line 8A of the line 8 onto the plane 9 is obtained as the movement course. This line 8A is corrected on a basis of an angle 13 between the face 7 and the plane 9, namely, between a perpendicular 12 of the plane 9 and the optical axis 11, thus obtaining dimensions and the shape of the outside circumferential line 8.

摘要： PURPOSE:To make possible highly accurate die position controlling by operating die position deviations and position deviations owing to deflection from a crank angle detector, a load detector, a die position detector, etc. and disposing servo-valves for controlling the die positions by the above-mentioned signals. CONSTITUTION:In a horizontal opposed type forging machine having mechanisms of driving dies 5 to a sine wave shape, a die position detecting scale 14, a crank angle detector 26, and a hydraulic force detector 23 (this becomes a load detector when multiplied by a cylinder area) are provided, and the servo valves 16 which operate cylinders 2 based on the correction signals from position deviation correcting circuits 30-38 which compare the signals from said angle detector 26 and position detector and the signal from the die position setter 24, operate the position deviations of the dies 5 and operate the position deviations by deflection based on the signal from the load detector. With the above-mentioned constitution, the dies are moved sinusoidally and the die positions may be controlled highly accurately with less impact.

摘要： The method involves holding a tubular workpiece (1) in a handler (2) that includes a passage (6) aligned with a bore (7) of the workpiece. A rod is provided to carry a mandrel and formed with a centering guide (8) having outside guide diameter smaller than inside passage diameter and greater than outside rod diameter. The mandrel is inserted into the bore through the passage while sliding the guide along the passage and centering the rod in the passage by the guide. The workpiece is externally engaged around the mandrel with forging tools such that the workpiece is forged around the mandrel. An independent claim is also included for a pipe-making apparatus comprising a handler.
