摘要： PURPOSE:To automatically produce an uneven sheet in a short time by producing a rugged sheet nearly equal in shape to a corrugated sheet from a flat sheet with a roll forming tool and then obtaining squareness of a corner part of the rugged sheet with a right angle finishing device. CONSTITUTION:The flat sheet 23 is passed between an upper and a lower roll 9 for forming a rugged sheet of a roll forming tool 10 to form a rugged sheet 24 nearly equal in shape to the corrugated sheet. Then, the uneven sheet 24 is positioned and set to pieces 20 between an upper and a lower frame body 15 of a right angle finishing device 11, cylinders 17 are elongated, the frame bodies 15 are pressurized through push members 16, wedges 14, 13 in such a direction that they approach to each other and the pieces 20 pressurize the uneven sheet 24 in a vertical direction. Synchronizing with this, the pieces 20 are energized by uniform force through push bars 22, cross bars 19, springs in a lengthwise direction to compress the rugged sheet 24 uniformly in the lengthwise direction. Consequently, the corner parts of the rugged sheet 24 are finished to right angles to produce a perfect corrugated sheet.

摘要： PURPOSE:To automatically produce a corrugated sheet of complex shape by working a flat sheet to obtain a corrugated sheet, then, pressing it with a forming tool at a stroke. CONSTITUTION:The flat sheet 11 is passed between a upper and a lower roll each of which bites with the other to form a corrugated sheet and worked in a corrugated form to produce a corrugated sheet 12 having a pitch equal to that of a corrugated sheet 10 to be produced. Then this corrugated sheet 12 is set between an upper and a lower forming tool so that the position which is shifted by a prescribed pitch from the center of the corrugation of the corrugated sheet 12 comes into contact with the corner part of the forming tool 9. Shearing and deformation are given by simultaneous pressing to the corrugated sheet 12 to produce a corrugated sheet 10. In this way, the corrugated sheets 10 can be produced in a short time and automatically and mass- production of the corrugated sheet 10 is realized.

摘要： PURPOSE:To reduce press loads and improve the product yield by chamfering top and bottom faces at both ends of a slab by use of chamfering metal dies having a tapered groove and then edging the slab by a vertical face of edging metal dies. CONSTITUTION:A metal die 1 consisting of chamfering metal die 1' and an edging metal die 1'' having a vertical face is held on a metal die holder in a stacked state. The holder 2 is mounted on a frame 3 enabling the dies 1' and 1'' to change to each other to be freely go up and down. First, a vertically driving device 4 positions the die 1' to abut on a slab 7 and chamfering top and bottom ends of the slab 7 is performed by use of a draft driving device 5. Then, the slab 7 is edged by the die 1''. Press drafting loads are reduced because edging is performed on the chamfered slab 7. Further, the yield of rolled products is improved because dog bones 11 and fishtails of the slab 7 are reduced.

摘要： PURPOSE:To roll a ring blank in the radial direction only and to shorten a ring rolling stage by combining both ends after forming a metal plate of rectangular section in the metal plate having sectional section by rough-rolling it and making a ring blank and executing the ring rolling. CONSTITUTION:The metal plate 1 of rectangular section is subjected to rough- rolling by the upper and lower rolling rolls 5, 6 having the uneven shape approximate to the sectional shape of a manufacturing ring stock. After forming it in the metal plate 7 having the necessary sectional section it is bent by a press or roll, etc., both ends are joined by welding and the ring blank 8 having a sectional section is formed. Then, the ring blank 8 is subjected to ring rolling between upper and lower grooved rolls 3, 4. Consequently the ring rolling may surface only by making the ling blank 8 of correct radial dimension.
