摘要： PURPOSE:To ameliorate a hydraulic cold straightening method for a work with strain generated by welding, to shorten a line required for the straightening and to reduce a space in a stage after the straightening and to simplify the device. CONSTITUTION:This is composed of plural vertically movable lift rollers 6 installed corresponding to the length of a work W as a strain straightening object, rails 5 arranged along the lift rollers 6 and a strain straightening device which is provided so that it can run on the rails and has straightening heads 4 provided with straightening and working rollers 2 and a pressure receiving roller 3. The lift rollers 6 move vertically in sequence according to the travel of the strain straightening device and a conveyor to carry in and out the work in the direction orthogonally crossed with the running direction of the strain straightening device is provided.

摘要： PURPOSE:To easily and stably support an assembly member provided with three- dimensional curved surface shape on a flat base platform and to eliminate hindrance to various work carried out on the assembly member. CONSTITUTION:Each of supporting jacks 1, which are standingly arranged all over a flat base platform 2 and support, an assembly member at multiple points, is formed in such ways as fitting an elevating cylinder 12 inside a supporting cylinder 11, fixing a nut member 14 screwed to a screw shaft 13 rotating on the axial center of the supporting cylinder 11 and the elevating cylinder 12 to the elevating cylinder 12, and fitting the nut member 14 inside the supporting cylinder 11 with its rotation restricted. The elevating cylinder 12 is pressed by a screwing advance of a nut member 14 according to the rotation of the screw shaft 13, so that height adjustment is carried out by telescopically extending/contracting the elevating cylinder 12 against the supporting cylinder 11. This adjustment is easily carried out by normal/reverse rotation driving of the screw shaft 13, in other words, carried out by extension/contraction of the elevating cylinder 12 employing the supporting cylinder 11 as a direct supporting body, so that rattling of the elevating cylinder 12 caused by the lateral directional force working on the head part 10 at the tip is prevented, and as a result, the assembly member placed on the head part 10 can be stably supported.

摘要： PROBLEM TO BE SOLVED: To surely correct strain regardlessly of the thickness of a material to be corrected by extending one end of a rotating shaft in the axial direction and making a part of plural drive rollers movable to a retreated position not facing plural pressure rollers thereby moving an unnecessary drive roller to the retreated position. SOLUTION: A flat plate block, 10 consists of a thick flat plate 10a, two drive rollers 31 are moved to a second guide part 26b of a lower moving guide 26 and a first guide shaft part 32, remaining two drive rollers 31 are positioned having a prescribed distance with driven rollers 24, 25. The flat plate block 10 is placed on each drive roller 31, at the state that the driven rollers 24, 25 are lowered and brought into contact with the flat plate block 10, by driving/ rotating a transfer roller and each drive roller 31, the flat plate block 10 is transferred. At this time, each driven roller 24, 25 applies a prescribed pressure force to the flat plate block 10, plural line strains of the flat plate block 10 are simultaneously and continuously corrected.

摘要： PURPOSE:To effectively combine a trans-web against a longeron fixed on a skin plate. CONSTITUTION:In advance, to combine a part of a peripheral side part 3c, at least, of slots 3a formed along a side periphery of a trans-web 3 onto a longeron 2, bending is executed so as to enlarge the sectional area of the slot 3a. After that, in a state of hanging the trans-web with a crane, each slot 3a is faced to one end of the longitudinal direction of the longeron 2, the trans-web 3 is laterally moved while fitting the slot 3a onto the longeron 2 and positioned at a prescribed position with the crane and a gutter 8, after it is tacked on a large plate 1, the bent peripheral side part 3c is bent back and the trans-web 3 is welded and fixed on the large plate 1 and the longeron 2.

摘要： PURPOSE:To simplify the structures of a drive system and a control system for adjusting completely promptly the height of plural supporting jacks which support an assembling member having a three dimensional curved face a base. CONSTITUTION:Transmission shafts S1-S8 are extended along the arranging rows of supporting jacks 1, 1... disposed lengthwise and breadthwise onto a flat base, and the supporting jacks 1, 1... corresponding to them are connected to them through electromagnetic clutches K, K... disposed separately. The rotation of the transmission shafts S1-S8 is driven by driving motors M1-M8 disposed separately, and is transmitted to the supporting jacks 1, 1... by the engagement with the respective electromagnetic clutches K, K.... By expanding or contracting the supporting jacks 1, 1... individually, it is possible to carry out height adjustment.
