摘要： PURPOSE:To enable automatic bending at plural bending points of a metal-made band-like work (e.g. Thomson edge material, etc.) in the longitudinal direction. CONSTITUTION:A swing bar 6 is turnably arranged in the horizontal plane centered on the bending position O, and a following member 10 is positioned at this free end side and shiftably supported in the longitudinal direction of the swing bar 6 and used to a work feeding means, as well. In the following member 10, a main clamp 11 for holding the rear end part of the work W and a sensor 12 for following the work W to turning displacement, etc., are arranged. Further, one set of bending dies 1 is made to be changed with automatic type changing device containing a turret table 4, etc. At the time of starting the bending by bringing one set of the bending dies 1 close with one pair of bending cylinder 20, the work W is displaced while turning to the direction of bending and further, the swing bar 6 and the following member 10 are turned so as to follow the work.

摘要： PURPOSE:To improve the accuracy for bending a knife by clamping and fixing the knife mounted on a surface plate from the both sides through a clamping mechanism. CONSTITUTION:This is a device for bending the knife for punching the sheet used when a pattern having a prescribed shape is punched on the sheet, etc., into a prescribed shape and the knife A mounted on a surface plate is clamped and fixed by a clamping mechanism 8 by a set of clamping members 8a, 8b on the both sides. The camber of the knife A is corrected under this state. The knife A is bent by a working die mounted on a base 25 oscillated and driven by a motor 35. The bent radius of the knife A is made equal to the same bending force as such bending is performed. Therefore, the knife can be worked so that an accurate bent radius can be obtained to the back of the knife.

摘要： PURPOSE: To quickly form a scalloped cutting edge on the peripheral edge of a knife blank in a single operation by using a set of a punch and a die. CONSTITUTION: A punch 31 is lowered, and is brought into contact with a die 33, and an upper surface of a blade part 53 of a knife blank 49 is pressed by a surface 41 of an insert 39 of the punch 31, and its outside edge part is pushed in a recessed part 45 of the die 33, and a scalloped cutting edge is formed in the blade part 53 of the knife blank 49. That is, a scalloped dimple 55 composed of a projecting part projecting from a bottom surface of the blade part 53 of the knife blank 49 and a recessed part recessed from an upper surface, is formed on the outside of this bottom surface 59.

摘要： PURPOSE:To improve efficiency of edging work, by folding a curved side edge of each edge unit, integrally formed through a cut groove, while cutting the point end side of said curved side edge so as to be in the same level with a side surface of the edge unit and forming a curved one-edge point in every edge unit. CONSTITUTION:A sheet of plate-shaped edge unit element material 1, performing press working, integrally forms each edge unit 4 through a cut groove 3. Next the material 1, folding each curved part 2 by press working so as to form an acute angle theta with respect to one side surface 4a of the edge unit 4, continuously forms each curved folding part 5 while provides a round hole 6 penetrating through the edge unit 4. Further the material 1, simultaneously edging the point end side of each curved folding part 5 to be polished and cutting it in a line A so as to be in the same level with the other side surface 4b of the edge unit 4, forms a curved one-edge point 7 in every edge unit 4. The material 1, simultaneously performing this work in the above for each edge unit, provides effectiveness for improving efficiency of the edging work.

摘要： PURPOSE:To manufacture a plyer by cold press-working by using a steel plate as a stock by selecting the thickness of a steel plate stock in accordance with the required thickness of a pivotally holding part, at which two pieces of unit bodies are cross attached to each other and are pivotally held by a pin. CONSTITUTION:The thickness of a stell plate stock is selected basing on the desired thickness of an unit body 3 of a finished plyer A at a cross-pivot holding part 5. On side face of a product stock blanked at the 1st stage is flushed with one side face of the nonbulged part 5 at the 2nd stage, and the thickness of a bulging part is made to two times the thickness of nonbulging part by providing a warp to the stock. At the 3rd stage, a part predetermined to be a holding front-tip part is inserted in a die, and is press-formed into the holding front-tip part 4. A gripping part 6 is bulged at the 4th stage, and a continuous chevron- shaped edge is formed at a holding piece 41 of the part 4 at the 5th stage. An unit body 3 of plyer a formed in this manner is heat treated, and then the two unit bodies 3 are pivotally attached to each other in one body by a pin 7.
