摘要： PURPOSE:To simplify installations so as to improve productivity by suspending a shape steel by a pair of right and left chain blocks movably suspended on the horizontal support beam of a portal frame mounted across a conveyor with springs interposed between the beam and the chain blocks in the title adjuster of the shape steel on the conveyor. CONSTITUTION:On the horizontal support beam 5 of a portal frame 6 mounted across a roller conveyor 4, chain blocks 1, 1 are movably suspended by rollers 9 and the respective chain blocks 1, 1 are symmetrically connected by means of springs 8 in relation to the support beam 5. In this constitution, when an H-shape steel 2 is hoisted by the chain blocks 1, 1, the chain blocks 1, 1 approach to or separate from each other on the horizontal support beam 5 according to the tension or the reaction of the springs 8, 8, in response to the width of the H-shape steel 2 due to gravity. Thus, a chain 3 is located in its vertical posture at the central part in a direction of width of the conveyor 4 and stabilized. In such a way, the constitution can be simplified and productivity can be improved.

摘要： PURPOSE:To improve the welding accuracy and to reduce the welding cost by setting three-dimensional rectangular coordinates on material to be welded and classifying a weld line executing group capable of welding at one position of a welding robot and then, performing welding successively for every group. CONSTITUTION:A traveling carriage 12 on which the welding robot 11 capable of executing the articulated automatic position control is mounted is provided and positioners 13 to hold the material 15 to be welded freely turnably at both ends of a longitudinal axis are arranged. At this time, the positioners 13 are arranged so that the material 15 to be welded can be fixed for every 90 deg.. Three- dimensional axes X, Y and Z are set on a steel frame joint 15 and the Y axis is coincident with an axis of rotation of the positioners 13. A computer 14 classifies the stopping position of the carriage 12 and the torch position into groups for every turning angle of 0 deg., 90 deg., 180 deg. and 270 deg. of the positioners 13 and welding is performed successively for every group. Since a simple program can do, the welding accuracy is improved and the welding cost is reduced.

摘要： PURPOSE:To efficiently perform electroslag welding by performing electroslag welding while supplying a welding wire having the specified diameter along an inclination to the specified position. CONSTITUTION:Welding is performed with a diaphragm 1 inclined by an inclination theta=2-30 with respect to verticality. Backing materials 15 are welded in the vertical direction in contact with side thick plate materials 7 along the front and rear of both ends of this diaphragm 1. Inclined welding grooves 9 for electroslag welding surrounded by the inner sides of the side thick plate materials 7, both sides of the diaphragm 1 and the inner sides of the backing materials 15 are formed. Electroslag welding is performed while the welding wire 17 having 1.6-2.4mm diameter is supplied along the inclination to the position deviated in the horizontal direction by 1=[10-30]Xtantheta(mm) to the inclined lower side from a center line of the inclined welding grooves 9 from a nonconsumable nozzle 18. Consecquently, the mechanical performance of a diaphragm inclined electroslag weld zone of the box pillar can be maintained satisfactorily.

摘要： PURPOSE:To mechanise the work to cut a diaphragm fitted to a beam connection part of a box pillar for building from a raw material plate and produce the same. CONSTITUTION:A first truck 57 and a second truck 58 travel in the longitudinal direction of raw material thick plates 3 on a longitudinal rail 56 and a first guide frame 59 and a second guide frame 60 are mounted freely movably in the breadthwise direction of the raw material thick plates 3, respectively on the first truck 57 and the second truck 58. In order to form a groove for welding on both sides of the raw material thick plates 3, inclined cutting work is performed by two cutting torches fitted to the first guide frame 59 to form the inclined surfaces. Meanwhile, the raw material thick plates 3 are cut in the breadthwise direction by one cutting torch 63 fitted to the second guide frame 60 to produce the diaphragm with specified dimensions having the inclined surfaces for the groove.

摘要： PURPOSE:To reduce the welding working time by interposing insert material such as low carbon steel having the melting point higher than base metals into a groove root joint part between the base metals to perform welding and preventing burn through to the rear by the unmelted remainder of the insert material. CONSTITUTION:The burn through to the rear can be prevented by a very simple means that the insert material 5 is interposed into the groove root joint part between the base metals 1. Complete melting of the insert material is prevented and partial penetration is carried out by using the low carbon steel or very low carbon steel having the melting point higher than the base metals 1 as the insert material 5. Further, in order to improve strength of a weld zone, the quantity of partial penetration of the insert material is increased and the insert material is almost molten and it is necessary to perform gas metal welding work under conditions that the burn through does not take place on the rear. By this method, the welding working time is reduced and the satisfactory welded joint part can be made.

摘要： PURPOSE:To achieve automation of carrying a steel plate in and out of a roller conveyer. CONSTITUTION:A plurality of magnets 22 are mounted on the lower end of a lifting cylinder 13 loaded on a running flame 8, and a steel plate 1 is magnetized by the magnet 22, and is lifted thereby. The running frame 8 is run by a running cylinder 10, and the steel plate 1 magnetized by the magnet 22 is moved on a roller conveyer 3. Since this system is magnet type, in which the magnet 22 is demagnetized and is removed from the steel plate 1 after the steel plate 1 is lowered on the roller conveyer 3 by the lifting cylinder 13, handling can be carried out even when there is a hole 2 on the steel plate.
