摘要： PROBLEM TO BE SOLVED: To realize miniaturization, light weight, and low costs of a swaging processing device, and improve a shape accuracy of a swaging processing part. SOLUTION: Plural dies 5 which are concentrated at the center and form a work insertion hole are arranged movably in a radial direction, and a swaging hammer 7 is installed outside each die. The swaging hammer 7 is struck by a swaging roller 13 revolving around a periphery of the swaging hammer 7 to move the dies 5 towards a centripetal direction, so that a work W is reduced in diameter. When processing, both work ends are held, and the work is inserted into and pulled out from a work insertion hole 10 while the work is rotating around the axis on at least one of the work holding parts 15, 18.

摘要： PROBLEM TO BE SOLVED: To facilitate the removal of scrap by surely returning the scrap punched out with a piercing punch back into the hole, in the piercing-working for piercing the hole on a pipe with the piercing punch when a hydraulic-pressure bulge-working is applied.
SOLUTION: In the piercing-working for piercing the hole 13 on the pipe 1 by moving the piercing punch 11 forward and back in the sheet thickness shearing direction of the pipe 1 when the hydraulic-pressure bulge-working for forming the bulged part on the pipe 1 is applied by arranging the pipe 1 in dies 2, 3 and applying the inner pressure and the axial compressed load to the pipe 1, firstly, the top end surface 11a in the piercing punch 11 and the inner surface 2a of the die, are positioned at almost the same surface level. This working contains a first process in which the bulged part is formed on the pipe 1 with the hydraulic pressure bulge-working, a second process in which the hole 1a is semi-punched on the pipe 1 by advancing or retreating in the sheet thickness shearing direction of the pipe 1, and a third process in which the hole 13 is perfectly punched out on the pipe 1 by retreating or advancing the piercing punch 11 in the reverse direction to the second process.

摘要： PROBLEM TO BE SOLVED: To easily and precisely form a groove in axial direction of a tube. SOLUTION: A mandrel is inserted into at least a section to be worked of a tube, and the tube and the mandrel are held so that they do not move relatively. The tube and a die are relatively moved in the axial direction so that the tube is inserted into the die. A plastic flow is caused in tube material by a protrusion part 7 protruded from the die 5 to form a groove in the axial direction of the tube on the surface of the tube. A working face 10 of a front edge of the protrusion part 7 is inclined to have a sweepback angle for a relative advancing direction as well as is formed to a projecting curved face in the relative advancing direction, the plastic flow of material is promoted in the center direction and peripheral direction of the tube.

摘要： PROBLEM TO BE SOLVED: To make it possible to efficiently manufacture a deformed part which protrudes long from the axis part by applying a swaging processing to a product of monolithic forming.
SOLUTION: A plurality of dies are arranged movable in the radial direction which gather in the center and form a workpiece insert hole 9 with a noncircular cross section. The workpiece is machined through a process to form a deformed part on the workpiece with a noncircular cross section by not rotating the dies 4a to 4d and the workpiece W relatively, and a process to form a reduced-diameter part on the workpiece with a circular cross section by relatively rotating the dies 4a to 4d and the workpiece W.

摘要： PROBLEM TO BE SOLVED: To form a reduced diameter part and a serration in a single process and easily and accurately form the serration in a hollow pipe having the serration in the inner surface of the reduced diameter part. SOLUTION: A die 7 for reducing the diameter of the end part of a pipe material 12 is disposed on the outside of the pipe material 12. A core metal 8a formed in an irregular shape for serration formation is disposed in the end part of the pipe material 12 on the side where the die 7 is disposed. A load is applied to the other end part of the pipe material 12 to push the pipe material 12 into the die 7 so as to move the core metal 8a in the same direction of the pressing direction for the pipe material 12. Thus the reduced diameter part and the serration can be formed at the end part of the pipe material 12.

摘要： PROBLEM TO BE SOLVED: To manufacture burring worked part having a flange part extended from a metallic sheet by minimizing the bent part on the inside of the root (outside of bending) without generating buckling on the outside of the root of the flange part.
SOLUTION: The flange part 1b having a tapered outer periphery surface, which is extended from the metallic sheet 1a and whose outer diameter is gradually reduced toward the tip is formed by burring and is made a semi-manufactured product. A punch P having an outside diameter which is approximately same as the inside diameter of the tip of the flange part is arranged movably on the same axis as the axis of the flange part and also a die D having the inside diameter which is approximately same as the outside diameter at the tip of the flange part of the working target is arranged. The flange part of the working target is formed by relatively driving the punch and the die to the metallic sheet so that the inner peripheral surface of the die is moved to the metallic sheet while pressing the tapered outer peripheral surface of the semi-manufactured product from the tip of the flange part of the semi-manufactured product in the state where the punch is present in the flange part of the semi-manufactured product.
