摘要： PURPOSE:To prevent a necking phenomenon and to improve the yield of product, by providing a fly wheel to a driving system of pressing roll arranged between a finishing rolling mill and a down coiler, and keeping the peripheral speed of the pressing roll equal to the peripheral speed of roll of the finishing mill. CONSTITUTION:A pressing force P of a roll pressing device R equipped with a pressing cylinder 15 is set to a proper value in accordance with the sheet thickness and breadth of a strip 2, in rolling a strip of thin sheet thickness. Then, hydraulic pressure is transmitted to the cylinder 15 from the side A of a pipe 19 to expand a gap between pressing rolls 12 in order to release the pressing force acting on the strip 2, after the strip 2 is wound around a mandrel 5 of a down coiler to some extent. At this time, the peripheral speed of pressing roll is kept in the constant speed approximately equal to that of the roll of the finishing mill by the effect of fly wheel 16, because the fly wheel 16, having a moment of inertia larger than that of the pressing roll 12, is provided to the driving system R, accordingly; the generation of necking is prevented.

摘要： PURPOSE:To control the sectional form of a rolled material by giving a speed difference between upper and lower work rolls and thereby reducing the amount of flexure of the rolls due to rolling reaction force. CONSTITUTION:Rolling is performed keeping the peripheral speed of the lower work roll 4 constant and making the peripheral speed of the upper work roll lower than the above. The thickness at the center and end of the rolled material is measured with a thickness meter. When it is detected that the plate thickness in width direction is thick at the center, the peripheral speed of the upper work roll 3 is reduced to make the plate thickness uniform. Then, the speed difference between the upper and lower work rolls 3, 4 becomes greater and the rolling reaction force and amount of flexure becoms smaller. Thus, the difference of plate thickness between the center and end of the rolled material can be eliminated without changing the crowning of the rolls.

摘要： PURPOSE:To make possible the control of the sectional shape of the rolled material without frequently interchanging the roll, by giving the horizontal bend to the intermediate rolls of the rolling mill so as to make narrow the gap of intermediate rolls at the middle part, on purpose to adjust the deflection of the work roll. CONSTITUTION:A couple of upper and lower work rolls 2, 3, a couple of upper and lower backup rolls 10, 11, on outside of work rolls 2, 3, and at least a couple of horizontal intermediate rolls 6, 7, between work rolls 2, 3, and backup rolls 10, 11, are arranged. The rolling load impressed on the backup rolls 10, 11, is transmitted to the work rolls 2, 3, through the intermediate rolls 6, 7, and compresses the rolled material 14. Hereupon, by actuating the cylinder-piston mechanisms 16, 17, 18, 19, the intermeidate rolls 6, 7, cause the horizontal elastic deformation, and displace from the solid lined position to the dotted lined position; hereby, the roll gap of the intermediate rolls 6, 7, is made narrower at the middle part than that on both sides. As a result, the roll 2 is deflected into a downward projecting arc shape, and the rolled material 14 receives the compression strongly at its middle part.

摘要： PURPOSE:To forge easily spiral parts having good shape and quality by allowing the lubricant forced into the spacing between the blank material in a die and the die to remain in the die under a specified pressure until the forging is completed. CONSTITUTION:A blank material A is set in a die 5 and is pressed with a punch 4. A lubricant B is fed under the prescribed pressure in the spacing between the die 5 and the material A through a lubricant passage 7 by a lubricant feeder 6 at the point of the time when the material A is filled in the die 5. When the pressurization on the punch 4 is continued, the material A is smoothly fitted to the die 5 by the lubricant B and is easily molded. On the other hand, the lubricant B is escaped through a relief valve 10 into a tank 11 upon pressurizing of the punch 4 so that the pressure of the lubricant B in the die 4 can be maintained constant. The remaining lubricant B forces upward the molded part by its pressure and a knock-out 12 upon completion of the molding thereby parting the molded part from the die. Said lubricant acts also to lubricate the molded spiral vane surface.
摘要翻译：目的：通过使强制进入模具中的坯料与模具之间的间隙的润滑剂在规定的压力下保持在模具中直到锻造完成，从而容易地形成具有良好形状和质量的螺旋部件。构成：坯料A设置在模具5中并用冲头4压制。润滑剂B通过润滑剂供给器6通过润滑剂通道7在模具5和材料A之间的间隔中以规定的压力供给在材料A填充在模具5中的时刻。当冲头4上的加压继续时，材料A通过润滑剂B平滑地装配到模具5并且容易地模制。另一方面，当加压冲头4时，润滑剂B通过安全阀10逸出到罐11中，使得模具4中的润滑剂B的压力能保持恒定。剩余的润滑剂B在模制完成时通过其压力和脱模12向上施加模制部件，从而将模制部件从模具分离。所述润滑剂还用于润滑模制的螺旋叶片表面。

摘要： PURPOSE:To forge easily and inexpensively spiral parts by forging a blank material to the spiral parts then changing the temp. of dies to form a clearance between the dies and the molded parts and parting the molded parts from the dies while rotating the same. CONSTITUTION:A die 10 and a punch 11 which are forging dies are formed of a material which forms molding dies having a prescribed size at a molding temp. and has the coefft. of linear expansion smaller than that of a desired molded part 12 in the stage of forging a molded part having a spiral part around the central axis. A blank material is put into said die 10 and after the material is heated to the molding temp., the punch 11 is forced into the die to forge the material. The punch 11 is then drawn and the die 10 and the molded part 12 are cooled. A high pressure fluid P such as air is acted in the clearance 8 between the die 10 and the part 12 generated by the dimensional shrinkage that arises on cooling so that the part 12 is floated from the die 10. Such part 12 is pulled from the die while the part is rotated around its axis and the parting of the part from the die is thus easily completed.
