摘要： PURPOSE:To detect wall face position and groove shape of a welding groove in a single side wall face only through a longitudinal range finder. CONSTITUTION:A longitudinal range finder 1, which can traverse in parallel with an abutting member, is disposed above a welding groove while a reflector 2 is disposed above the abutting member and the longitudinal range finder 1 is moved from the reflector 2 toward a single side wall face. In such process, position and inclination of the single side wall face are detected at first through the reflector 2. The longitudinal range finder 1 is then moved to the wall face in order to detect the groove shape on the abutting side. Entire profile of the groove is then calculated based on the position and inclination of the single side wall face and the groove shape on the abutting side.

摘要： PURPOSE:To carry out a bending process in good order, by pressing-in the ridgeline of the tapered surface of an extremely thick board member and a bending inside plane crossed together, with an upper metallic mold provided with an expanded section. CONSTITUTION:A tapered surface 7 is set upward on a lower metallic mold 2, and an extremely thick board member 3 is set so that the axis of symmetry of upper and lower metallic molds 1, 2 may coincide with the axis of symmetry of the extremely thick board member 3. After that, when the upper meatllic mold 1 is pressed downward and the extremely thick board member 3 is transformed in a crescent shape, then the ridgeline 6 of the tapered surface 7 and a bending inside plane 5 crossed together is projected in the direction of the upper metallic mold 1. When the upper metallic mold 1 is pressed further downward, then the ridgeline 6 is pressed-in by the expanded section 4 of the upper metallic mold 1. By this method, the downward pressure of the upper metallic mold 1 is uniformly transmitted also to the tapered section 7 of the extremely thick board member 3, and a bending process is carried out in good order.

摘要： PURPOSE:To efficiently and accurately measure the groove position and shape by disposing a horizontal range finder and a vertical range finder above a welding groove and oscillating and moving both range finders. CONSTITUTION:The vertical range finder 1 is arranged in the square direction to the different surface in level of the groove and moved sidewise in the orthogonal direction to the different surface in level. In addition, the horizontal range finder 2 is arranged in the direction in opposition vertically to the different surface in level and moved vertically. A data processor DPD collects bits of information 7 and 8 of distance signals of the vertical range finder 1 and the horizontal range finder 2 at specified pitches via A/D converters AD1 and AD2. The position in the horizontal direction of the groove one side wall surface and the height position and difference in level of the groove upper surface are detected from these bits of information. Since the height and position in the horizontal direction of welding members are detected independently by the vertical movement of the horizontal range finder 2, a function as a profile sensor of the welding groove with high accuracy under noncontact can be displayed.

摘要： PURPOSE:To prevent defects such as the cracking on the surface of a cord member and the deterioration of its material by heating a planar steel, hot- bending a top force and a bottom force and conducting dipping, heating and leaving under a cooled state in heating and cooling water tanks in succession. CONSTITUTION:A planar steel 2 is heated, and hot-bent by a projecting arcuate top force 6 and a recessed arcuate bottom force 7, thus forming a cord material 8. The cord material 8 is left as it is cooled up to room temperature in atmospheric air, heated, dipped in a cooling water tank, pulled up from the cooling water tank, further heated and left as it is cooled in atmospheric air. Beveling cutting sections 12 in the cord material 8 to which heat treatment is completed are removed, thus obtaining a large-sized arm 9. The large-sized arms 9 are held mutually from both ends centering around a rack material 13, and joining sections among the large-sized arms 9 and the rack material 13 are welded, thus forming a rack-and-cord. Accordingly, defects such as the cracking of the surface and the deterioration of the material can be prevented.

摘要： PURPOSE:To correctly measure the groove shape formed of a walllike member on one side by providing a vertical range finder and horizontal range finders on a supporting frame of a welding machine movable table to obtain the width and depth of the groove face and an inclination of the wall surface. CONSTITUTION:The vertical range finder 1 is fitted on a supporting member of the supporting frame 13 on the welding movable table and the distance to an object below it is measured. In addition, the horizontal range fingers 2 and 3 are fitted on the supporting member 12 fitted rotationally on the supporting frame 13 and the position in the horizontal direction of the object is detected. A data processor DPD (computer) collects distance (position) information in the horizontal direction of the groove wall surface 4 measured by the horizontal range finders 2 and 3 and distance (height; welding groove depth) information of the vertical range finder 1 when the vertical range finder 1 is moved sidewise till just before hitting on the wall surface 4 from the retreating position according to distance information in the horizontal direction. Signals of the range finders 1-3 are taken in a CPU via interfaces of A/D converters AD1-AD3, a counter PC1, etc. Consequently, the welding groove position and shape can be measured efficiently and correctly for the groove having the reverse inclination on the wall surface.

摘要： PURPOSE:To efficiently and accurately measure the depth and width dimensions at the optional depth position by obtaining depth information up to dummy members of members to be welded and the groove base and positional information in the groove width direction between the dummy members to be brought into contact with both sides of a narrow groove. CONSTITUTION:When a range finder 1 is arranged above the groove and traversed in the sate with the dummy members 5 brought into contact with both sides 3 of the narrow groove 2, information on the groove sides 3 below from both ends 35 of the groove of the steel surface can be also detected by the range finder 1 via the dummy members. The groove width dimensions at the optional depth position can be then measured by detecting the positions of the dummy member 5. In addition, since properties of the dummy member surfaces are remarkably superior as compared with the groove face, the positions of the dummy members 5 and 6 brought into contact with the groove base 4 and the narrow groove sides 3 are obtained by the range finder 1 as the stable and accurate information and the depth and width dimensions of the narrow groove can be calculated with high accuracy.
