摘要： PROBLEM TO BE SOLVED: To enable ensuring precision, rigidity and strength by making a cam insert/eject a punch, and carry out work, while correcting a predetermined height from a reference plane to the surface of a mounting stage for each work. SOLUTION: A cam 7 is provided with 10 plus several stages of steps. By moving the cam 7 according to the measurement result of a previous process, the relation between a stripper insert 8 and a punch 5 is set to a predetermined correction height. Since a punch 9 of a lower unit is supported by a normal pressure generator 11, it presses a mounting stage, following the correction height, changing in accordance with the relation between the stripper insert 8 and the punch 5. With such a structure, the correction quantity is fed back on the basis of the measurement result of the height from a chassis reference plane to the surface of the mounting stage in the previous process. The cam 7 is made to insert/eject the punch 5, so as to switch the predetermined correction height for each chassis, and the periphery of the mounting stage is constrained to carry out the correction work. Thus, the chassis satisfies precision, rigidity and strength as a metal plate chassis.

摘要： PURPOSE: To reduce the radius of the corner at which a work can be curled by fitting a roller tool in the inclined condition by the prescribed angle. CONSTITUTION: The curing of the end part of a work 2 by a roller tool 1 is suffiently encluded by using the part being brought into contact with a roller part 1a, and the inner side part 1b can be reduced by the displacement of the contact part through inclination. In addition, the curled end part is covered by the roller part 1a on the inner side part 1b by the displacement where the roller tool 1 is inclined. Though the roller tool 1 is bit by the end part after the roller tool is moved after working, the hitting can be avoided by reducing the length of the inner side part 1b as the recess. The radius (r) of the inner side part 1b can also be reduced by the displacement by reducing the inner side part 1b, and the radius R of the corner at which the end part is worked can also be reduced.

摘要： PURPOSE:To improve the safety and the working accuracy in piercing by using a rotary type lifter for supporting a product and making the product-piercing direction the same as the vertically moving direction of a press, in forming a titled die. CONSTITUTION:When the working operation of press is started, a lifter 1 is turned around a supporting pin 3 at a prescribed timing by a push-down pin 12. When the press is further lowered, a product 2, set by the lifter 1, is attached to a die 9 in an inserted state, and is pressed by a stripper 14 to piece it by a punch 13 and the die 9. In this way, a hole is pierced in the slant surface of product without deflecting the punch 13 in the die, and the safety and the product accuracy in working are improved.

摘要： PROBLEM TO BE SOLVED: To provide a rotor which can improve the efficiency of a motor and a generator, and reduce manufacturing cost. SOLUTION: This rotor is formed by layering steel sheets, and is constituted of a rotor iron core 2 involving a number of slots 8 formed by means of punching in its layered direction, a conductor block 7 integrally-formed with the first short-circuit ring 4 by means of molding at the one end of a conductor bar 3 of bar shape inserted into the respective slots 8, and the second short- circuit ring 5 welded to the other end of the conductor bar 3. It is thus possible to improve rotational performance by eliminating an increase in electric resistance due to a welded part between the conductor bar 3 and the first short- circuit ring 4, and reduce processing cost and assembling cost by integrally- forming the conductor bar 3 and the short-circuit ring 4 at a time.

摘要： PURPOSE:To prevent the damage of a mold at an abnormal rotation time by forming part of the profile shape of a product in a circular shape, and setting a working stage to enable to form a profile punching die shape in a circular form. CONSTITUTION:A punching portion except a circular shape of a product is formed in the step A. The round shape portion of the product is punched in a profile punching stage in the step B. The step A is always disposed before the step B. When the working stage is formed in this manner, a punch is formed in the product shape, and the die is formed in a circular shape. Thus, even if a die of the profile shape is abnormally rotated, the cutting edges of the punch and the die do not interfere with each other, but instead can perform punching.

摘要： PURPOSE: To achieve the appropriate curling to a dissimilar cylindrical body. CONSTITUTION: A roller 1 achieves the curling to a main body part of relatively large diameter at the end part of a dissimilar cylinder by being guided by a guide groove 14 of a disk-shaped cam 12 while the normal tangential contact condition is kept. The roller is oscillatable to a part of smaller diameter than that of the main body part, and the curling is achieved by being guided by a cam groove 16 formed on a part of the guide groove 14 while the roller is moved changing the angle so as to keep the tangential contact condition to the end part, leading to the smooth curling where the tangential contact condition is kept to the whole end part.
