摘要： PURPOSE:To form different kinds of drawn square tubes by changing a part of components. CONSTITUTION:The male die 12 of a forming die 11 has a male main body 14 in a truncated square conical shape and a supporting plate 15 on which the male die is mounted and fixed. The male die main body 14 has a horizontal bottom surface 14. A supporting plate 15 has a square bottom surface 14a, an upper surface 15a of the same shape and a peripheral inclined overhang part 15b which is detachable. A female die 13 has an inner surface 21a in the truncated square conical shape corresponding to the male die main body 14. For example, when a three-face drawn square tube is formed of material for the three-face drawn square tube being the angular steel tube in which both end faces inclinet at a specified angle is put on the male die 12, the material for the three-face drawn square tube is set vertically. When the female die 13 is lowered, it is drawn by the pressure and the three-face drawn square tube is obtained. When the support plate 15 is exchanged, a two-face drawn tube or four-face drawn square tube can be formed.

摘要： PURPOSE:To caulk and joint the lapped vertical part having good shearing surface with sharp bending by cutting and inclining the lapped vertical part with the cutting off tool and the receiving groove of the rolls, and bending the formed pawl chip deep further by using the roll. CONSTITUTION:The metallic strip is bent vertically and lapped, the formings 1 of the deck plate, etc., having the lapped vertical part 2. The above lapped vertical part 2 is clamped with the cutting off roll 22 and the blade receiving roll 24, the pawl chip 25 is cut with the cutting off tool 21 and the receiving groove 24 able to fir the above in set on respective circumferential surfaces. At the same time, this pawl chip 25 is stood by the proper inclination angle with the inclined surface of the upper surface of the above cutting off tool 21, and making a pawl out. Next, the above stood pawl chip 25 is bent deeper further and bent back between the pawl bending roll having the pawl bending surface 31c and the cylindrical roll 32. If necessary, after the bending back angle is increased by using the other pawl bending roll, the pawl chip 25 is clamped with a pair of cylindrical rolls (not shown in figure) and the lapped vertical parts are jointed close.

摘要： PURPOSE:To safely and efficiently enable the laying of floor panels by using floor panels fitted with 4-legs, 2-legs, and 1-leg supporting legs, and by arranging them so as to be mutually supported making a reference of two reference lines in the perpendicular two directions of the supporting legs of 4-leg floor panel. CONSTITUTION:The steel ball 18 on the panel support 17 of a supporting leg 12 is pressedly fitted in the engaging hole 19a of a grommet 19 of an elastic material that has been fitted to the corner part of a floor panel 10, and the supporting leg 12 is fixed to the corner part of the floor panel 10. And, making reference lines p, q of the lines that are extended in the directions of the two sides of a 4-leg floor panel A, two corner parts with no leg of a 2-leg floor panel B are fixed on the panel supports 17 of the two supporting legs 12 of the existing 4-leg floor panel, and then, in the consecutive order, 2-leg floor panels are arranged in the p and q directions. In the interior region surrounded by the regions S1 and S2 in the perpendicular two directions, 1-leg floor panels C are successively arranged from that which is near to the point O of intersection of the reference lines and they are extended in all directions to complete the laying of floor panels. Thus, work efficiency can be enhanced, and working hours can be shortened.

摘要： PURPOSE:To raise efficiency of roll recomposition by engaging the fork portion of a lifting jig holder on a hooking block as the fork portion is raised in parallel to the connection rod of roll gear. CONSTITUTION:A lifting jig 44 and a holder 49 is lowered by operating a hoist 40 so as to fit the connection rod 29 of a roll gear 20 to a 'U' shape groove on the fork portion 50a of the holder 49 and then, by raising the lifting jig 44, the fork portion 50a of the holder 49 comes in contact with a hooking block 33 as the fork portion 50a rises by the guidance of the connection rod 29. by further raising the lifting jig 44, an upper chock 25 and an upper roll 23 are lifted and, by continuously raising the lifting jig 44, a lower roll 26 is raised together with a lower chock 28 as a dropping out stay member provided at the end of the connection rod 29 comes in contact with the hooking block 33 of the lower chock 28 and thus the upper and the lower rolls 23, 26 are raised in one unit. The roll 23, 26 recomposition thereby can be made efficient.

摘要： PURPOSE:To automatically and suitably adjust the clearance between rolls according to the plate thickness of a steel plate by receiving the forming load of a rolling roll or a working roll with plural belleville springs having a specific spring characteristics when a steel stock is cold-rolled, worked by plural forming units to manufacture a channel steel material, etc. CONSTITUTION:Material 2 to be formed such as steel plate is passed through a guide stand 3 and six stages of horizontal roll stands 4 (P1 - P6) for the special purpose of driving and light weight channel steel, etc., are rolled and worked by non-driven forming units 5 (R1 - R10) equipped in the middle. When the steel plate stock 2 is worked by the forming unit 5 into the channel steel, the load for a web 2a, forming roll 12, a flange 2d, forming roll 13 and an abutting roll 14 for forming a lip part is received by plural belleville springs made of material having specific spring characteristics, each clearance between rolls is adjusted automatically according to the thickness of the steel plate 2 passing through each roll and the plate thickness of a product thin section can be adjusted freely.

摘要： PURPOSE:To manufacture a roll which is high in its use efficiency, and is inexpensive, by bend-forming like a ring a flat square material or a profile, and fitting it to a base material being an inside roll. CONSTITUTION:A flat square material 1 of die steel is bend-formed like a ring by a roll 2, and thereafter, its both ends are joined by flash butt welding 3, by which a ring 4 is formed. This ring 4 is used as an outside ring roll of a necessary part and is fitted to a base material 5 being an inside roll. In this way, as for the ring 4 which is welded after bend-working the flat square material 1, its shaving amount is small, therefore, the use yield is extremely high, and also the working expense is low.

摘要： PURPOSE:To simplify adjustment of width between sectional rolls, and to prevent a variation of width of the roll due to rotation of a nut in the course of work, by engaging the sectional roll of a forming roll and the nut for shifting the roll, by use of a plate spring and a ratchet. CONSTITUTION:When a rotary ring 13 is rotated against elasticity of a plate spring 19 fitted into a ratchet 16, by holding a handle of the rotary ring 13, a bent part of the plate spring 19 is engaged with each crest of the ratchet 16, and a nut 6 is rotated around an outer shaft 3 of a stationary roll shaft. Since the nut 6 is screwed into a screw 5 of the shaft 3, it is moved in the axial core direction, rotating around the roll shaft. Since a projecting part 6a of the nut 6 is fitted into a sectional roll 8 so as to be freely rotatable, when the nut 6 moves to the right and left in the axial core direction, the sectional roll 8 is also guided by a guide groove of the shaft 3 and moves to the right and left in the axial core direction.
