摘要： PROBLEM TO BE SOLVED: To prevent damage to a knife or a movable die by changing motor speed to specified rate of the motor speed when the movable die is reciprocatively moved during the movable die which is reciprocatively moved by being driven with the motor acts on side parts of the knife. SOLUTION: By repeatedly pressing a die 24 for working which is reciprocatively moved in directions of arrows 28a, 28b against the side parts of the long size sheet-like knife A which is sent out in a longitudinal (an arrow 27) direction in synchronism with the reciprocating movement of the die 24 for working, the knife A is successively bent. Based on a servomotor 30 whose rotational speed is steplessly adjustable and with which its set speed is maintainable, a sensor 101 for detecting travel quantity of the die 24 for working and the travel quantity of the die 24 for working which is detected with the sensor, during the die 24 for working acts on the side parts of the knife A, speed setting of the servomotor 30 is changed to the rotational speed V2 which is 10-50% of the rotational speed V1 of the servomotor 30 when the movable die 24 is reciproactively moved.

摘要： PROBLEM TO BE SOLVED: To provide a flexibility with a device so that the same bending machine can bend a band material of different size in thickness or in width and the like in a bending processing of a Thomson blade (a hooped blade) in a desired shape, with which a punching, for example, of a cardboard and the like into a developed box shape or other shape is carried out. SOLUTION: On a band material holding member 5, the band material paths 6 and 7 of different size are formed in a two stored shape which can pass through each of the band materials of different sizes in thickness and the like respectively. A band material holding member 5 is elevated by a motor 15 via a screw driving mechanism 14 so that either of the paths 6 and 7 is positioned at a bend processing point P. A bending sleeve 10 is rotatably engaged in the outside of the member 5 as a moving bend tool. Bending parts 10a, 10b installed at both sides of an opening 10d, are pressed against a band material W being extruded from an exit of the path 6 or 7 and bends the material W to the right or left. When a sort of the material W is changed (a log change), the member 5 moves upward so that, for example, the path 7 is positioned at a bend processing point P for carrying out the similar bending processing under that condition.

摘要： PROBLEM TO BE SOLVED: To decrease the thickness of a cutting blade and produce no blanking waste by arranging the cutting blade along the cross direction of a strip member on the opposite side to a counter blade with the strip member interposed between the blades. SOLUTION: A counter blade 44 and a cutting blade 40 are integrally moved in the cross direction of a strip member 1, that is, in the vertical direction between the cutting position for performing cutting and the retreat position spaced upward from the cutting position by a designated distance. In the cutting position, a slit 44a of the lowered counter blade 44 is positioned in such a manner as to be aligned with a feed path of the strip member 1 from a bending holder 2, and the strip member 1 from the bending holder 2 is supplied between one blade part 44b of the counter blade 44 and a corresponding blade part 40b of the cutting blade 40. The cutting blade 40 is so constructed that according to the rotary moving direction, one of the blade parts 40b cuts the strip member 1 in a space up to the corresponding blade part 44b of the counter blade 44.

摘要： PROBLEM TO BE SOLVED: To efficiently cut a band-like arc-shaped blade of various radii of curvature with excellent accuracy by providing length measuring means of an arc of a blade edge of the band-like arc-shaped blade. SOLUTION: Measuring means G to measure the length L of an arc of a blade edge 1 of a band-like arc-shaped blade A comprises a reference disk 39 to be fixed to a lower end of a rotary shaft 33 and a measuring instrument 40 to measure the circumferential length L' (feed circumferential length) when the reference disk 39 of the arc is rotated. An indication part 9 obtains the length L of the arc of the blade edge 1 of the band-like arc-shaped blade A with excellent accuracy by performing the operation to convert the pulse number to be fed from the measuring instrument 40 by the formula. In the formula, R0 is the radius of the reference disk 39, and R is the known radius of curvature of the band-like arc-shaped blade A. The function capable of inputting the conversion ratio R/R0 is the so-called pre-scale function.
