摘要： PROBLEM TO BE SOLVED: To prevent the deflection of a hard roll in the case of molding a small-sized and long-length cylinder when the cylinder is obtained by using the hard roll and elastic rolls into which the hard roll bites.
SOLUTION: A work is subjected to cylindrical molding by a freely rotatable hard roll 1 and a pair of first elastic roll 2 and second elastic roll 3A rotating so as to mutually be confronted to the hard roll. In this case, the press-contact position of the second elastic roll to the hard roll is deflected from the semi-circumferential place of the press-contact position of the first elastic roll to the hard roll toward a direction opposite to to the rotating direction of the hard roll. Further, a third elastic roll is press-contacted to a position deflected from the semi-circumferential place of the press-contact position of the first elastic roll toward the rotating direction of the hard roll.

摘要： PROBLEM TO BE SOLVED: To eliminate a residual straight line part which is left when forming a curved surface. SOLUTION: After inserting a plate shaped stock 1 between elastic roll 3 and hard roll 2, both rolls are normally rotated one turn or over. The starting edge A of the plate shaped stock is positioned on the hard roll side, a termination B is positioned on the elastic roll side, they are overlapped with each other, and are passed through between both rolls. After that, both rolls are reversely rotated, the termination of the plate shaped stock is positioned on the hard roll side, the starting edge is positioned on the elastic roll side, they are overlapped with each other, and the plate shaped stock is passed through between both rolls. After that, both rolls are normally rotated, and the plate shaped stock is passed through between both rolls without overlapping the starting edge and the termination of the plate shaped stock.

摘要： PURPOSE:To form a stock into a shape having a required diameter automatically by setting a pressing member between the stock and a roll to be pressed of a roll bender provided with two rolls and shifting the contacting point between the pressing member and the stock during pressing. CONSTITUTION:An end of a stock to be worked is abutted on the contacting point between a pressing roll 22 being in a pressing state and a roll 24 to be pressed and the pressing roll 22 is rotated by a motor. Thus, the stock is drawn between both the rolls 22 and 24 so that the roll 24 begins to rotate. The stock is bent into a circular arc shape with the roll 24 inside and is delivered from the opposite side of both the two rolls by succession of that rotation. The forming work is performed so that the stock is bent and expanded in a reverse direction because the pressing member 26 exists between the roll 24 and the stock, and moves as if the stock wraps the roll 24. In that time, the contacting point between the pressing member 26 and the stock is shifted by turning a handle 167a or a motor. In this method, a formed body having a complicate curvature such as a perfect circle, spiral, ellipse, triangle, square, etc. is formed.

摘要： PROBLEM TO BE SOLVED: To unnecessitate the preparation of many kinds of hanging hooks corresponding to rigid roll, to reduce a manufacturing cost and to shorten the time needed for changing work by fitting an annular groove of the rigid roll to a supporting groove of a supporting member. SOLUTION: A U-shaped supporting groove 12 notched upward to fit to the groove 4 of the rigid roll 3 is arranged to a stand-up wall 11 of the supporting member 10. A pocket part 13A is secured by arranging the stand-up wall 11 at the front part of one pair of projecting walls 13, 13 and a part close to the groove 4 of the rigid roll 3 can be housed into this pocket part 13A. This supporting member 10 can be elevated/lowered to an arbitrary position by screwing a screw 15 hung down so as to be freely rotatable from the upper part of the forming device body 1 into a screw hole 14 to rotate the screw 15.

摘要： PURPOSE: To provide a method for pushing/bending a cylinder with high accuracy by simultaneously pressing opposite female dies using a cylindrical male die and female dies which are equally divided into even-numbered pieces which are moved forward and backward toward the axis of this male die. CONSTITUTION: A material W to be formed is arranged on a 1st female die 11 and the 1st die 11 and 2nd female die 12 which exists on the opposite side across the male die 1 are simultaneously pressed toward the male die 1. Then, the lower part of the cylinder is formed. The 1st female die 11 is left in the position as it was and only the 2nd female die 12 is retracted. Two remaining 3rd female 13 and 4th female die 14 are simultaneously pressed toward the male die 1. In this way, the right and left parts of the cylinder are formed. After the 2nd female die 12 is advanced toward the male die 1 with the 1st female die 11, 3rd female die 13 and 4th female die 14 held in the positions as they were, these four female dies are simultaneously pressed toward the male die 1. In this way, the upper part of the cylinder is formed. As this state is held, the male die 1 is drawn out and working is completed.
