摘要： PURPOSE: To mount a protector in a pipe end in a short time by providing a shrinking means of a protector holder and an expanding means of a protector according to a size of a pipe and a caulking means of a caulking piece. CONSTITUTION: A protector 12 is placed at a positioning position by a positioning device 23, and a rod 22 of a hydraulic cylinder 21 is made to protrude to have a moving table 16 moved toward a steel pipe 11 by a predetermined distance. This movement causes a holding claw 39 and expanding/caulking part 70 of respective mounting heads 17 to be loosely fitted into the protector 12. Then a shrinking motor 42 is used to move the three holding claws 39 and the expanding/caulking part 70 in directions opposite to each other along a slide rod 28 to have the protector 12 supported at three points and positioned on a caulking means of a caulking piece. The rod 22 is made to further protrude to have the table 16 moved toward the steel pipe 11 so that the protector 12 is mounted in the steel pipe 11 and caulked by the caulking means thereby allowing it to be fixed.

摘要： PROBLEM TO BE SOLVED: To provide a scrap guide which discharges a trimming scrap generated by trimming a side edge of a metal band by means of a side trimmer, wherein the scrap guide is prevented from being clogged with the trimming scrap and can quickly eliminate the clogging even if it occurs.
SOLUTION: The scrap guide 3 for the side trimmer has two hard material portions on an inner peripheral surface thereof. The hard material portions are each formed of a tool steel for cold work or a cermet, and arranged at an intermediate portion of the curved scrap guide 3 and an outlet portion 12 of the same. One or both of the hard material portions have a cylindrical shape enclosing the inner peripheral surface of the scrap guide 3.

摘要： PURPOSE:To satisfactorily perform butt welding of sheets by displacing clamps to hold two sheets in the relative inclination and height directions between both sheets. CONSTITUTION:A backing metal 6 movable vertically is provided between outlet side and inlet side clamping devices 4 and 5 supports selectively the lower surfaces of strips 2 and 3. In addition, auxiliary clamping devices 8 and 9 are provided at the outlet side and inlet side and hold butt ends of both strips 2 and 3 with the backing metal 6 attached to execute positioning at the time of welding. The clamping device 4 supports the strip 2 from the upper and lower sides by upper side and lower side cylinders 11a-11c. The clamping device 5 also has the same structure and the height and inclination of the strips 2 and 3 can be displaced separately. Consequently, even if warps and sags by cutting are caused on the sheets, the height can be coincident in parallel with the butt ends and a satisfactory weld bead shape can be obtained.

摘要： PURPOSE: To allow a protector to be mounted into the end part of a pipe regardless of the size of the protector by providing a protector holding part and a means for expanding/contracting the holding part according to the size of the pipe. CONSTITUTION: When a rotary shaft 32 is rotated onto the diameter enlarging side by an expansion motor 42, a nut 34 moves forward, and each umbrella rib like arm 37 is rotated outside around a pin 36 so as to hold a protector 12 in a vertical-lateral four-point supported state from the inside. While keeping a holding state by holding claws 39, each holding claw 39 is pushed into the end part of a steel pipe 11, with a guide roller 41 as the head so as to mount the protector 12 into the steel pipe 11. The protector can thereby be held positively regardless of the size and mounted into the end part of the steel pipe. In addition, structure is simple so as to facilitate the manufacture, and the equipment cost can be reduced.

摘要： PURPOSE:To cut preceding and succeeding plates without distinguishing them from each other and to butt-weld them with high precision by clamping a preceding plate and cutting the tip part thereof, then, moving and clamping a succeeding plate, cutting off its tip part at the same position as the cut off position of the preceding plate, then, welding the butt parts of both plates. CONSTITUTION:The preceding plate 1 is clamped to cut off its tip part, then, the tip part of the succeeding plate 2 is moved above or below the preceding plate 1 to clamp the succeeding plate 2. The tip part of the succeeding plate 2 is cut off at the same position as the cut off position of the precceeding plate 1, then, the butt parts of the cut off end faces of both plates 1, 2 are welded. Therefore, high-precision butt free from individual distinction by a cutter and from the influence of stop error by the movement of a welding device and by the movement of the plate is carried out to obtain stable welding.

摘要： PURPOSE:To provide a simple device which permits simultaneous swiveling and lifting with a simple driving system by engaging an inside cylinder which is erected, is successively provided with a swiveling arm in the upper part and can be driven to move upward or downward and an inside cylinder which is fitted and fixed thereto by a spiral guide groove and engaging member. CONSTITUTION:The outside cylinder 12 is fixed to a hearth 27 as a fixing member and an electrically driven cylinder 13 is attached to the lower part. The spiral guide groove 15 is fixed to the surface of the inside cylinder 14 and the swiveling arm 16 is successively provided to the upper part. The cylinder 14 is connected via a bearing 17 to the cylinder 13. A swiveling guide roll 18 is attached as an engaging member to the upper step part A of the cylinder 12 and is made rollable in the groove 15. Four supporting rolls 19 are attached to the upper and middle step parts A, B of the cylinder 12 so as to contact with the cylinder 14. The cylinder 13 is risen in order to rise and swivel the arm 16. Then the cylinder 14 rises as well and the force in the swiveling direction is applied to the cylinder 4 by the engagement of the roll 18 with the groove 15, by which the cylinder 14 and the arm 16 are risen and swiveled. The descending and swiveling of the arm 16 are executed by the same principle.
