摘要： PURPOSE:To facilitate forming and to combine dissimilar metals by fitting with the tube stock of the other part by forming a pullout stopping groove on the joining face of the tube stock of one part and plastically flowing one part of the other part of the tube stock to the pullout stopping groove by executing drawing by a die. CONSTITUTION:An annular pullout stopping groove 12 is formed in advance at fixed intervals on the outer peripheral face of a small diameter tube stock 11 formed by a hard material. Small and large diameter tube stock 11 and 13 are fitted each other, a core bar 14 is inserted into the small diameter tube stock 11 and passed through a die 15, and drawing is executed by drawing it. Thus, the inner diameter of the small diameter tube stock 11 is formed in the dimensional shape corresponding to the outer diameter of the core bar 14 and the outer diameter of the large diameter tube stock 13 is formed in the dimensional shape corresponding to the inner diameter of the die 15. One part of a soft material tube stock 13 easy to deform is subjected to plastic flowing to the pullout stopping groove 12 of the hard tube stock 11, and both are integrally fitted and the composite pipe 16 having large tensile strength is obtained.

摘要： PURPOSE:To continuously produce an ultrathin sheet in the same manner as in ordinary rolling by moving the thin sheet along the top and bottom surfaces of belt-like members and subjecting the same to rolling in the form of plural layers, then stripping the rolled ultrathin sheet from the belt-like member. CONSTITUTION:The thin sheet 1 which is wound to a thin sheet coil 3 is fed via deflector rolls 7 along the top and bottom surfaces of the endless belt-like members 4 driven by rolls 10. The three-layered sheet consisting of the thin sheets 1 on the top and bottom surfaces and the member 4 is passed through rolling rolls 5 to roll the thin sheet 1 to the ultrathin sheet 1' and thereafter the sheet 1' is stripped from the member 4 and is taken up to the thin sheet coil 3'. The production of the ultrathin sheet is thus made continuous in the same manner as for ordinary rolling.

摘要： PURPOSE:To prevent the oscillation of a cup-shaped grinding wheel by pressing the grinding wheel to a rotating body in such a manner as to come into contact with the surface of the rotating body within the range sandwiched by two parallel lines tangent with the inside diameter of the grinding wheel thereby grinding the rotating body. CONSTITUTION:The cup-shaped grinding wheel 3 is brought into contact with the surface of a work roll within the range H0 from the horizontal line X-X running the axial center of the grinding wheel up to the horizontal line C-G tangent with the inside diameter D1 of the grinding wheel. The wheel 3 is driven to rotate by the rotating force of the work roll, by which the work roll is ground in a non-driving system. The generation of a point of inflection by the wear, i.e., local inclination, is obviated on the cup surface of the grinding wheel and the cause for the generation of a clatter is eliminated by grinding the work roll in the above-mentioned manner.

摘要： PURPOSE:To grind uniformly a roll with a grinding device made into a simple construction by using just one grinding wheel for a piece of the roll, grinding the entire width of the roll and rolling over the grinding surface near the transverse central part of the roll. CONSTITUTION:The grinding wheel G is started from the point A at the body end of the work roll 1 and the roll 1 is ground toward the transverse central part S thereof. The axial center of rotation of the grinding wheel G is inclined inward by an angle thetawith the normal of the roll surface and one side of the cup surface of the grinding wheel is pressed to the roll surface, then the wheel G is rotated according to the rotation of the roll 1. The wheel G is detached from the roll surface when the wheel G arrives at the point B near the transverse central part S of the roll. The grinding wheel G is then retreated to the position B' and rolled over to the position C' where the angle theta of inclination of the axial center of rotation of the wheel G is inverted and again the grinding wheel is pressed to the roll surface as shown by C. The roll is ground toward the point D at the other roll body end. The wheel arrived at the point D is moved in the opposite direction and the roll is again ground to the point C. The wheel is retreated and rolled over at the point P and the roll is ground between B and A.

摘要： PURPOSE:To enable to accumulate numerous strip plates in a small place and to perform easily the direction change of the strip plate as well by arranging a small diameter roll group spirally along the route of the strip plate to be wound on the outer peripheral surface of a conical member. CONSTITUTION:A big conical member 20 to surround a small conical member 10 is arranged on the outer side thereof and the strip plate 1 having passed through the roll 6 of the inlet port of an accumulator passes through the opening part 20a which is provided on one part of the big conical member 20 and is wound on the small conical member 10 that a small diameter roll group 21 is arranged on the outer peripheral surface thereof. The strip 1 which has moved the small diameter roll group 21 of the big conical member 20 by return is then passed through the roll 7 of the outer part and flowed to the next stage. Now the strip 1 is flowed to any direction according to the plate passing method.

摘要： PURPOSE:To grind efficiently a rolling roll without causing a nicking of whetstone by pressing a whetstone against the surface of a rotating roll and slanting the whetstone reversely to the rotating direction with respect to the direction of a rotating center of rolling roll. CONSTITUTION:In grinding a rolling roll 1 by pressing a whetstone 2 against the surface of rotating roll 1, the pressing direction of whetstone 2, with respect to the direction from a contact point between the whetstone 2 and the roll 1 to a rotating center C, is slanted so that the pressing force F has a component in the direction reverse to the rotating direction of roll 1 shown by the arrow. A degree of 5-40 deg. angle is preferable for a slanting angle theta of whetstone 2. In this way, a reaction against the pressing force of whetstone 2 is relaxed, and the reaction acting on the front-end lower part BM of whetstone 2 is reduced, and the nicking of whetstone 2 is prevented.
摘要翻译：目的：通过将磨石压在旋转辊的表面上并相对于轧制辊的旋转中心的方向与旋转方向相反地倾斜砂轮，可以有效地研磨轧辊而不会产生磨石的切痕。构成：通过将砂轮2压靠在旋转辊1的表面上，将砂轮2的推压方向相对于从砂轮2与辊1的接触点到旋转中心C的方向进行研磨，倾斜，使得按压力F具有与箭头所示的辊1的旋转方向相反的方向的分量。一度5-40度角度对于砂轮2的倾斜角度θ是优选的。以这种方式，减轻了磨石2的按压力的反作用力，并且作用在砂轮2的前端下部BM上的反作用力减小，防止了砂轮2。

摘要： PURPOSE:To achieve a continuous compression simulating test for rolling a plate such as steel plate at a high accuracy, by making a rolling test piece passing reciprocatively between a pair of rolling rolls with the space therebetween adjusted by a hydraulic pressure as desired. CONSTITUTION:A hydraulic oil is fed to a hydraulic cylinder 26 with a hydraulic controller 27 to lower an upper anvil 21. As a specified space between upper and lower rolling rolls 23 and 24 reaches a specified value, the space between both upper and lower anvils 21 and 22 is detected with a space detector 28 to stop the feeding of a rolling test piece W. The rolling test piece W having a max. thickness testing section at the center thereof is inserted between the upper and lower rolling rolls 23 and 24 and grasped with chucks 31 and 32. The test piece W is pulled through a working rod 29a with a hydraulic cylinder 29 to make the test art between the rolling rolls 23 and 24 and then, pulled reversely with a hydraulic cylinder 30 with the space therebetween narrowed by a required value. In this manner, the test piece W is reciprocated specified times to perform a rolling simulating test.
