摘要： PURPOSE: To change the shearing width of metal bands by turning a nut fitted movably parallelly to the axis along the key groove in the outside surface of the outer shaft and allowing the circular cutting edge to shift parallelly to the axis.
CONSTITUTION: A pair of circular cutting edges 1a, 1b and 2a, 2b, the right and left, are fitted on the upper and lower shafts 1 and 2, respectively, where the edges 1a and 2a shall shear one side of a metal band longwise and the edges 1b and 2b shall the other side to yield a strip of material with a specified width L. When the edges are to be moved, the edge shift nut 9 is rotated around the shaft 1 for movement in parallel with the shaft, that will shift the cutting edge 1a in engagement with a hook-shaped projection parallelly to the axis in the same direction as the nut 9 guided by a guide groove, so that the space between the cutting edges 1a and 1b can be adjusted into any intended dimension easily and accurately.

摘要： PURPOSE: To form a metallic pipe with a special cross section symmetrical vertically and horizontally by means of a small quantity of forming energy and also a small number of roll steps. CONSTITUTION: A metallic pipe 1 with a special cross section, which is provided with a bulging part 1b on the left and right, a recessed part 1c on top and bottom in the center and a pair of upper and lower corner parts 1a and which is symmetrical vertically and horizontally, is formed by roll forming for example. A square pipe 11 is used as a base stock. The square pipe is put through plural steps of roll cavities designed such that the four corners 11a of the square pipe 11 become the four corners 1a of the pipe 1 with the special cross section, and thus, the square pipe is formed into the desired pipe with the special cross section. Since the square corners 11a are already made, a small quantity of forming energy and a small number of roll steps are sufficient for the production. The equipment cost is low, productivity is high and the manufacturing cost is curtailed.

摘要： PURPOSE:To easily and efficiently execute the knock-out. CONSTITUTION:A square pipe stock 1a is deep-drawn with a truncated square conical male die 8 and a female die corresponding to this male die to manufacture a tapered square pipe 1. One pair of stoppers 9 faced to the upper part of the male die 8 are arranged so as to be slidably in the horizontal direction. The stopper 9 is energized to the outer part of the male die 8 with a spring 13 and projecting from the outer peripheral surface of the male die 8 in the ordinary condition. When the female die descended at the time of squeezing, the inclined inner surface of the female die is brought into contact with the tip of each stopper 9, and each stopper 9 is shifted to the center direction of the male die 8 by the component of force in the horizontal direction. At the time of executing the squeezing formation, as ordinarily the tapered square pipe 1 is press-stuck to the inner surface of the female die, at the time of using the female die, the tapered square pipe 1 ascend together with the female die, but the ascending is stopped by hitting to the stopper 9, and the tapered square pipe is separated from the inner surface of the female die. In such a way, the knock-out is automatically executed in the press movement without needing a special process for knock-out.

摘要： PURPOSE:To easily knockout when a tapered square tube is drawn. CONSTITUTION:The tapered square tube 4 is obtained by drawing a base stock square tube by a male die 16 and a female die 19 with the initial pressing of a ram 20. At that time, the tapered square tube 4 is brought into press- contact with the inside surface 19a of female die 19, an upper bolster 25 is inserted between the lower surface of ram 20 and the upper surface of a knockout block 22 and a lower bolster 23 is inserted in the lower part of female die 19 before the second pressing of ram 20. When the ram 20 is lowered, lowering of female die 19 is stopped by the lower bolster 23, the knockout block 22 is directly applied with the main pressurizing force of ram 20 with the upper bolster 25 and the tapered square tube 4 which is in press-contact with the inside surface 19a of female die 19 is knocked out by push-lowered. Since strong main pressurizing force of a press machine is utilised, knockout work is smoothly carried out.

摘要： PURPOSE:To efficiently recombine rolls when the size of a formed product is changed and to eliminate the need for a crane. CONSTITUTION:The feed drive for a metal plate is carried out by exclusive pinch rolls 23, 25, 27, 28 for feed drive. A lip part is formed at a lip forming zone 24, a flange part is formed at a flange forming zone 26 after the lip part is formed, The lip forming zone 24 is made up of one kind of roller die face plate unit 70 and used in common for different sizes of products. The flange forming zone 26 is provided with three exclusive roller die face plate units 31, 32, 33 corresponding to three product sizes in parallel so that they form three lines of a central line, and right and left lines. Further, all groups of these roller die face plate units are made so that they can move right and left in one body. When the size of the product is changed, all the groups of roller die face plate units are moved right or left and a desired roller die face plate unit is used.

摘要： PURPOSE:To produce efficiently the tapered groove section having the lip and flange of high dimensional accuracy by using the upper die divided into three blocks and the lower die divided into four blocks. CONSTITUTION:Upper die 10 is descended with setting between upper die 10 and lower die 11 the metal cut stock having the prescribed taper in the longitudinal direction of the right and left both side edges and the plate stock is pressed into the recessed part for forming of the right and left side of the lower die 11 by the right and left side dies thereof. The right and left side parts of the plate stock is made to the prescribed tapered angle with the longitudinal direction and the bend formation is performed upward at the prescribed angle. The upper die 10 is then ascended together with a press head 14 and the side dies of the right and left are moved to the outer side. The upper die 10 is descended again and the plate stock is pressed into the recessed part of the two blocks of the center die 20 of the lower die 11 by a center die ' 12 and the right and left both sides of the center part of the plate stock are made to the prescribed tapered angle with the longitudinal direction. With the bend formation at the prescribed angle upward the tapered groove form stock having the lip 30 of about pentagonal section is obtd.

摘要： PURPOSE:To prevent lap occuring in an edge part by guiding a blank material of square-shaped tube, which is corner-bended to a welding roll having circular-arc- shaped upper rolls and butt-welding said material. CONSTITUTION:A blank material 5, which is corner-bended in the processes up to a fin-path-roll 9 and is formed into an open section of roughly square-shaped, is sent to welding rolls 10 in the next position. The material 5 is pressed from the periphery by the welding rolls 10, 15, whereby upper rolls 15a, 15b, having a radius of curvature R, in cooperation with the other rolls on 3 sides, keep the material 5 in the pressing status. Particularly, the overlap of faces 21, 22 into the tube is prevented, and the lap occurring in a welded face is eliminated, by the face-pressure through the upper rolls 15a, 15b. Then, butting the edge of an opening on the upward side face is butted and electrically welded, thereby a square-shaped metallic tube 12 having a welding juncture 11 on the upward side face is made.
