摘要： PROBLEM TO BE SOLVED: To reduce manufacturing costs and unnecessitate troublesome inventory management of a die by forming a camber without using the die. SOLUTION: A main roll 22 driven to rotate with a first servo motor is arranged in front of a table 19. A pinch roll 27 holding a plate spring stock between the main roll 22 and the pinch roll is arranged so as to vertically move in the position facing the lower side of the main roll 22 in the table 19. An upstream side sub-roll 30 and a downstream side sub-roll 31 are arranged so as to vertically move via ascending and descending mechanisms 32, 33 in the upstream side and the downstream side of the pinch roll 27 held the plate spring stack in the table 19. And both sub-rolls 30, 31 are abutted from the lower side to the plate spring stock held between the main roll 22 and the pinch roll 27 by vertically transferring both sub-rolls 30, 31, whereby, required bending is executed.

摘要： PROBLEM TO BE SOLVED: To obtain good yield without bringing about a mooted point of a conventional technique by hot extruding the base stock for wide shapes having a bended part in the middle and whose cross section is a U-shape or a V-shape and stepwise extending the bended part of the hot basestock just after that. SOLUTION: The billet 7 of an aluminum base stock is heated to a prescribed temp., also inserted into a container 3 and hot extruded. By this extrusion, the billet 7 of the base stock is passed through the forming hole 6 of an extruding die 1 and extruded as a base stock 8 for wide shapes bended into the U- shape having ribs at a prescribed interval in a cross section. The base stock 8 for wide shapes travels between the upper and lower roll devices 9, 10 of a roll forming device 2 arranged just after the extruding press. The extending of the base stock 8 for wide shapes is executed with the roll forming device 2. The U-shaped bended part of the base stock 8 for wide shapes is extended with the upper roll 13 in each stage of the upper roll device 9, flat formed into a wide shape 5. In this way, the wide shape having width to approximately twice the diametetr of the container is manufactured easily and accurately.

摘要： PROBLEM TO BE SOLVED: To unnecessitate the preparation of many kinds of hanging hooks corresponding to rigid roll, to reduce a manufacturing cost and to shorten the time needed for changing work by fitting an annular groove of the rigid roll to a supporting groove of a supporting member. SOLUTION: A U-shaped supporting groove 12 notched upward to fit to the groove 4 of the rigid roll 3 is arranged to a stand-up wall 11 of the supporting member 10. A pocket part 13A is secured by arranging the stand-up wall 11 at the front part of one pair of projecting walls 13, 13 and a part close to the groove 4 of the rigid roll 3 can be housed into this pocket part 13A. This supporting member 10 can be elevated/lowered to an arbitrary position by screwing a screw 15 hung down so as to be freely rotatable from the upper part of the forming device body 1 into a screw hole 14 to rotate the screw 15.

摘要： PROBLEM TO BE SOLVED: To simplify a welding process and eliminating a need for deburring, etc., and obtain a reinforcing member of the vehicle bumper device by bend a plate material and performing sectional formation, and welding both the end parts and bottom part of the plate material by a laser and then curving it upward. SOLUTION: The plate material 2 when entering a roll forming mold machine 3 runs between a couple of rollers 31a and 31b and is folded bent in order along the width. Each roller unit 31 is put in phase with an adjacent unit 31 gradually upward and the plate material 2 is formed into a cylindrical body 9 having a sectional shape as a bumper reinforcement 1. The cylindrical body 9 enters a laser welder 4 and both the end parts 2a and 2b which are made to abut against each other are welded together with the part 2d corresponding to the bottom wall. The completed cylindrical body 9 enters a three-point roll bending machine 5 and runs between rollers 51 and 53, and a roller 52, so that it is curved upward. Lastly, the body enters a cutting machine 6, which cuts it to specific length with a blade 61. Consequently, the bumper reinforcement is obtained from the plate material 2 through the simplified processes.

摘要： PROBLEM TO BE SOLVED: To simplify a support body holding mechanism by mutually opposing a pair of support bodies relatively slidably up and down and holding them freely liftably with a frame. SOLUTION: Lower rolls 2a, 2b are installed on the lower side of an upper roll 1 supported by a supporting device by supporting both ends freely rotatably and freely liftably respectively. In this supporting device, the lower rolls 2a, 2b are moved vertically up and down at the lower side of the both ends with a pair of supporting bodies 6, 6, further they are vertically driven synchronously. The lift is driven by a reciprocating rotary shaft 13, a crank part 14 and a rod 15 of the crank mechanism, etc., as the driving means. The lower rolls 2a, 2b are supported by a pair of supporting bodies, 6, 6, the means is installed in parallel before or behind them. Moreover, the supporting bodies 6, 6 are supported by a frame F. Therefore, even if the thickness of the work is changed, the precision for bending both ends can be improved.
