摘要： PURPOSE:To reduce manhour of working by forming a recess in a flat plate stock by the tip having a recessed part of a mandrel corresponding to inner diameter of the barrel and a hemispherical die having a projected part, forming the barrel by rotation of the mandrel and shifting of a spinning roller and forming the barrel of a recessed and bottomed pressure container. CONSTITUTION:A flat plate stock is held between the tip having recessed part of a mandrel X corresponding to inner diameter of the barrel and a die K having hemispherical projected part, and a recessed part is formed in the stock by pressure of an oil pressure cylinder YC. By rotation of a motor M supported by the mandrel X and joints BB, F, R of the die K and shifting of a spinning roller SR in longitudinal direction, projecting part of the stock is drawn to form the barrel A2. Thus, the bottom and barrel of the pressure container is formed from a flat plate stock by loading of one time to reduce manhour and lower the prime cost.

摘要： PURPOSE:To remove easily a habitual bent of strip by arranging a deflecter roll which is workable for the relational movement in the advancing direction of a strip and having larger diameter than that of a work roll. CONSTITUTION:A strip 1 is passed through in the direction of an arrow B in waves shape among work rolls 2, 3, 4, 5 with a tension given in the direction of an arrow A, A'. A deflecter roll C having larger diameter is arranged on the upper flow side of a work roll 5 of the final step and a deflecter roll on the rear flow side. Then the larger-sized deflecter roll C of the upper flow side only is made movable in the direction of an arrow E. The strip 1 is bent in an alternate direction while passing through among work rolls and the distortions in longitudinal and lateral directions are leveled and finally the distortion remaining in the longitudinal direction is easily removed by the movement operation of the large- sized deflecter roll C.

摘要： PURPOSE:To restrict the increase of the rolling load due to the reduction of the sheet thickness, and at the same time, to perform the shape straightening work, by successively decreasing the roll diameter along the traveling direction of the strip, and by giving the traveling strip the 3 degrees or larger feed-in angle, at rolling the strip being passed through pairs of large and small work rolls. CONSTITUTION:At rolling the strip S being passed through plural pairs of work rolls consisting of large and small work rolls 9, 10, 11, 12,..., etc., the diameter of these tandem arranged large and small work rolls 9, 10, 11, 12, etc., is successively decreased along the traveling direction of the strip S; the strip S, being given the 3 degrees or larger feed-in angle by the deflector rolls 29, 30, etc., is zigzag passed through these plural pairs of large and small work rolls; hereby, the rolling and straightening works are simultaneously performed. According to this method, even in case of requiring a high draft percentage, the rolling load can be reduced to a relatively small value, and besides, the strip with good flatness can be efficiently obtained by the rolling work.

摘要： PURPOSE:To lower the rolling load as compared with the conventional method, by arranging at least one reducing roll of thin diameter against the back surface of the strip traveling along the rolls while being bent into circular arc form. CONSTITUTION:The rolls 9, 10, of thin diameter with small radius of curvature are arranged so as to face against the rolls 3, 4, of the apparatus for straightening the distortion of the metallic strip 1 which is zigzag traveled sewing guide rolls 2-8 in the arrowed direction A while being given the tension. Since the outside surface of the strip 1, being curved with a small redius of curvature, is pressed, the outside surface is rolled to the flat and smooth plane by a very small rolling load, and also the action to help the bend of strip is given upon the strip. As a result, the apparatus can be miniaturized. Besides, if the strip 1 is made to travel along the rolls 3, 4, by changing the relative position of rolls 9, 10, against rolls 3, 4, and if the strip 1 is traveled so as to figure the character S, by arranging plural rolls, the frequency of bend and stretch is increased and the straightening action is improved.

摘要： PURPOSE:To make easy the design, operation, maintenance, etc., of the rolling mill, by arranging at specified opsitions a couple of secondary rolls and the primary forming rolls provided with the jig and the rolls of a peculiar shape, being connected through the spline to a couple of rotary shafts parallelly laid so as to be approachable to each other. CONSTITUTION:The chamfering apparatus for the corner of the rolled material 9 is constituted of the primary forming roll 10 and the secondary forming roll 13 being arranged on the downstream side of the roll 10; hereupon, the primary forming roll 10 consists of a couple segmented rolls 5, 5', and 6, 6', being borne on the bearing fitted to each of a couple of synchronously elevating rotary shafts 1, 2; and the secondary forming roll 13 consists of horizontal rolls 11, 12. The roll 10 is internally provided with the gap adjusting jigs 3, 4, respectively, and the outside of the roll 10 is fixed with the fixing jigs 7, 7', and 8, 8'; and the forming rolls 5, etc., are respectively provided with forming plane (f) with angle theta of inclination 20-70 degrees continuing to the restraint planes e, e, following to clearances d, d, at inner edges of the outer circumference. The secondary forming roll 13 possesses the same rolling direction as the roll 10 so that the rolled material 9 is chamfered without causing the shear droop, and the design and work are easier as compared with the caliber roll of the conventional method.

摘要： PURPOSE:To manufacture the ring body with good finished surface and high dimensional accuracy within a conventional roll working time, by arranging the working device for the outer surface of the blank, so as to keep the same relative position as the travel of the longitudinal reduction roll, and by compositely carrying out the rolling work and the outer surface work. CONSTITUTION:The ring blank 1 is rolled in the radial direction by reduction rolls 23, 24, and is rolled in the longitudinal direction by the cone rolls couple 25. Correspondingly to the increase of the radius owing to the rolling, the outer surface of the blank 1 is detected by the detecting roll 26, and an instruction is given to the traveler 29 by the position detector 27 and the position-set- and-control device 28 for detecting roll; hereby, the cone rolls couple 25 is controlled so as to occupy the suitable position. The housing 30 as the stand of the cone rolls couple 25 and the frame 37 as the stand of the cutter are made commonable; hence, the cutter is simultaneously traveled with travel of the cone rolls couple 25, and is stopped at the necessary position of the blank 1. Since the working position in the tool is previously settled, the cutting is started just the moment of the end of rolling for giving the necessary size of outer diameter to the blank 1, and then, the working is finished.

摘要： PURPOSE:To manufacture the good shaped ring body free from the under-fill at high accuracy and at high yield of material, by roll forming entire surface of the ring body using a pair of rolls for radially roll forming and more than three rolls for roll forming in the axial direction. CONSTITUTION:When the rolling blank for the ring body 23 is carried into the ring body rolling mill, the roll 25, roll 26 and roll 27 are respectively driven to rotate, and also, the roll 24 and the axially rolling roll housing 38 are radially moved toward the roll 25; and then, the radial rolling for the ring body 23 is started by the roll 24 and the roll 25. Since the roll 28 is held at the specified height from the beginning, the rolling for the portion (b) of the ring body 23 is started almost simultaneously with the start of radial rolling by the rolls 24, 25. Besides, when the portion (e) of the ring body 23 contacts with the roll 25, this is detected by the sensing tip 57, and the reduction due to the roll 27 is started by the control signal owing to this detected value; hereafter, the rolling for the portion (a) of the ring body 23 is carried out as far as the specified position; hererby, all portions a-f are roll formed by the rolls 24-28.
