摘要： PURPOSE:To enable bending a forming material at a large curvature without deforming the section thereof by inclining a rotating body attached with the plural 1st dies facing each other into which the forming material is inserted and supported by a desired angle. CONSTITUTION:When a base plate 10 is oscillated around a fulcrum shaft 11 connecting to a holder 2, the paths of the 1st dies 20a-20d and the 2nd dies for carrying a forming material are diagonally deviated by an angle theta. A blank forming material A is therefore curved at the axial line according to the angle theta. A worm gear 19 is turned in this stage to oscillate and rotate a rotating body 18 by an angle alpha in the direction opposite to the curving direction of the material A, so that the axial line direction of the material A is twisted by the dies 20a-20d. The oscillation and rotation are also transmitted to the 2nd dies on the discharging side of the material A, by which these dies are turned diagonally at the angle alpha.

摘要： PURPOSE:To make curvature of a forming material finely adjustable and to curve said material by changing the position of a pin connecting long sized arms thereby changing the curve formed by the long sized arms. CONSTITUTION:A guide pin 29 of a long-sized arm 23 is guided along a cam groove by moving back and forth a slide plate, by which the arm 23 is turned around a fulcrum pin 26 and the turning thereof is transmitted via a stud pin 28 to a long-sized arm 22. The arm 22 is thus turned around a fulcrum pin 25. The curvature formed by the arms 22, 23 is changed by such turning to the curvature at which a forming material A for a molding, etc. is bent. Supporting jigs 20, 21 such as mouthpieces are oscillated according to said curvature. When the position of the pin 28 is changed, the angle at which the arm 22 can be rotated is changed and the curve formed by the arms 22, 23 is changed.

摘要： PURPOSE:To form by extruding an elbow having a circular section without uneven thickness on the rear side by forming a curved forming part having the hole diameter decreasing gradually from the inlet to the outlet in a die and forcing a blank pipe having the outside diameter larger than the outside diameter of a product into the die. CONSTITUTION:The outlet diameter D2 in a curved forming part is made equal to the outside diameter of a target pipe to be formed and the curvature rho at the axial center near the outlet is made coincident with the curvature of the target pipe to be formed in a die hole 15 of a die 13 for forming an elbow. The diameter D1 on the inlet side is made larger than the diameter D2 on the outlet side to decrease gradually the size toward the outlet side. A straight pipe 2 having the outside diameter larger than the target diameter to be formed is used as a blank material and is positioned in an introducing part 16 of the die 13. Said pipe is then forced by a punch 12 into the die hole and is fed to the curved forming part. The previous pipe 2 is pushed out into the outlet 18 of the die hole by repeating said operation until the elbow which is the product is discharged.

摘要： PURPOSE:To form a bent pipe having no collapsion defect by introducing a bulging liquid pressure into a blank material pipe for bent while advnacing a movable forming die which forms the inside surface of the blank material pipe for bent. CONSTITUTION:A blank material pipe 10 for bent having a plug 27 inserted in its end is placed on a lower forming die 11, then an upper forming die is lowered by a die clamping press to grasp the pipe 10 between said die and the die 11, thereby applying a die clamping force thereon. A pressure oil is introduced into the advance port 24 of a pressurizing cylinder 22 to advance a pressing rod 19, and to move forward a movable forming die 17. The top end of the rod 19 is brought into contact with the end of the pipe 10 and the inside die cavity 18 of the die 17 is brought into contact partially with the inside of the pipe 10 by an initial pressing force F1. The initial bulging force is then introduced through an introducing hole 21 for the bulging liquid into the pipe 10. The initial pressing force is increased to compress the pipe 10 and the die 17 is further moved forward to increase gradually the bulging pressure. A spacer ring 26 is compressed to the position where it contacts with the forming die, and the forming is completed.
