摘要： PURPOSE:To contrive the reduction of the rolling time, and the improvement of the product quality without relying on the operator's intuition, by empolying the CMP unit for automatically controlling the rolling force at a specified sequence depending on the specified information inputted to the CMP unit, at controlling the rolling force of the ring rolling mill. CONSTITUTION:In the Wagner mill, the temperature and/or the dimension in the radial direction of the rolled material 1 are inputted to the CMP unit as control information; when this information coincides with the previously set standard value, the rolling work is executed following to the standard pattern of correlation between the outer diameter DA of the rolled material 1 and the radial rolling force FRA, being consituted of four steps to be decided according to the theroretical value and the actually resulted value. When the temperature is lower than the standard value, the rolling force is corrected so as not to permit any delay in the time necessary for making the outer diameter DA to be DA1 (when the temperature is higher than the standard value, the reverse corection is executed). After that, the second, the third, etc., sequential controls concerning the rolling reduction, the timing for changing the rolling force, etc., being stated in separate paragraph, are automatically executed; hereby, the reduction and uniformization of the rolling time, and the improvement and uniformization of the quality of the rolled product are effected.

摘要： PURPOSE:To easily forge the H-shape part of a specified dimension at a good yield, by gradually widening the gap between the opposite forming planes toward one of the punches, and by suitably shifting the die in the direction of axis of the punch before starting the forging work, on purpose to adjust the friction resistance between the blank and the tool. CONSTITUTION:The forming planes 1b, 1b, of the die 2 are formed so as to gradually narrow the mutual gap toward the punch 4, and this forming plane 1a is projected inward farther than other inner plane of the die 2. The length LC in the length L of the forming plane 1b is located arround the punch 4. The friction resistance acting on the flowing blank 5 is altered correspondingly to the length LC. On the other hand, the friction resistance acting on the flowing blank 5 is decided by the length LT of the land 3L. The thickness (t) of the adjusting liner 10 is adjusted for shifting the die 2 vertically; hereby, the length LC is altered, the friction resistance is adjusted, the length lB of the flange 6 becomes adjustable, and the length lT of the flange 8 can be also adjusted.

摘要： PROBLEM TO BE SOLVED: To minimize machining allowance of shaft parts in the forming method of a crankshaft shape material for which turning of the shaft part is eliminated with only grinding left workable.
SOLUTION: The impression profile 2b of the parts 1e, 1f other than the shaft parts 1a-1d is ground more than 2.0% of the shaft diameter each vertically from the center CL of the journal shaft part 2ba having complete roundness. Also, using a sizing mold 2 with an area reduction rate of the shaft part 3.0% or higher, the crankshaft shape material 1 is partially formed for sizing. After that, the accuracy-required shaft parts 1a-1d of this crankshaft shape material 1 is finished, with at least rough turning eliminated, to manufacture the crankshaft. In the sizing process, while both side faces of the shaft width are positively restrained, only the shaft parts are reduced to reinforce metal flow in the axial direction; therefore, uneven deformation of the shaft width left and right is suppressed, greatly decreasing the bend in the shaft width direction, and enabling the machining allowance of the shaft parts to be reduced by half in the subsequent machining process. Moreover, the service life of the tools to be used for trimming is prolonged.
