摘要： PROBLEM TO BE SOLVED: To obtain parts having characteristics equal to those by a COBAPRESS method in a short time at a low cost by taking out a premolding of Al or an Al base alloy at a specified temp. from a mold, executing natural aging in a furnace, next subjecting it to impact forging by split dies and thereafter executing cooling. SOLUTION: Al or an Al base alloy is cast at about 250 to 500 deg.C and is taken out from a mold. The obtd. premolding in a heated state is moved into a furnace and is subjected to natural aging at the natural aging temp. of the structural material thereof, e.g. at about 540 deg.C in the case of Al. At this time, preferably, as the furnace, a tunnel furnace is used, and the heat homogenizing time is changed in accordance with the desired mechanical properties. Next, this premolding finished with the treatment at the natural aging temp. is moved into a die in which cavities with dimentions slightly smaller than those of the mold are prescribed, stress is applied to two split dies, and impact forging/die forging are executed. The obtd. surface-roughened casting is subjected to additional natural aging as well according to need, is thereafter cooled by a room temp. cooling, accelerated cooling or quench hardening method and is finally subjected to annealing.

摘要： PROBLEM TO BE SOLVED: To provide a device for removing scale of a material to be rolled, especially shapes in which the device is composed of at least a spraying component assembly for a descaling agent to flow out of many nozzles comprising nozzle heads and flowing out openings and is constituted so that the material to be rolled is transferred beside the spraying component. SOLUTION: A spraying component assembly 1 is rotatably supported and is capable of being locked at a working rotation position and the nozzles form many nozzle sets 5 provided in the radial direction to the spraying component at intervals to each other. Then, these nozzle sets extend and stay along the rotation axis line of the spraying component. Further, each one set of the nozzle sets 5 is suited to a sectional profile of a shape 4 through which each of the nozzle sets 5 passes and is rotatable and adjustable.

摘要： PROBLEM TO BE SOLVED: To surely remove chips adhered to a work by forming a washing plate into an oblique roof form, and obliquely providing, on the washing plate, a discharge port of wash water with an oblique inclination toward the position where many chips are left of the work. SOLUTION: The chips by spot facing accumulated in the the recessed parts of a cylinder head W is removed by a wash water discharged from each discharge port 7 on an upper surface 2, and the chips left in this part are removed as it is scraped by the wash water obliquely blown to the lower surface center part of the cylinder head W through discharge ports 8 provided on both sides thereof. The chip removed from the lower surface of the cylinder head W are washed away by the upper surface 2 inclined in a roof form of a washing plate 1 without being left on the plate 1. At this time, the chips penetrated into the discharge ports 8 provided on the inclined surface part are also discharged downward by the wash water is charged from their large hole diameters without being left in this part.

摘要： PROBLEM TO BE SOLVED: To provide a feeder head sleeve capable of forming a top feeder head shape which can immediately apply a tip edge plate spreading type feeder head breaker without using a special jig even in the case of adopting the top feeder head. SOLUTION: A lost foam pattern 3 having a shape corresponding to a projecting part is assembled by penetrating a feeder head sleeve wall so that the projecting part abutted on one side of a tip edge plate in a tip edge plate spreading type feeder head breaker for breaking and separating a feeder head from a casting main body at the neck part thereof with the spread-out force of a pair of the tip edge plates opposite to each other, is integrally casted and formed with the feeder head.

摘要： PROBLEM TO BE SOLVED: To prevent the occurrence of defective quality caused by casting defect by pressing the surface with the pressure enough to crush blow holes without applying any shock. SOLUTION: The upper surface 2u of a cylinder block 2 is pressed by pressing pins 6 fitted to a pressing mechanism 4. The pressing mechanism 4 can be elevated/lowered and can apply a prescribed pressing force to the cylinder block 2 without applying any shock from the step when the tip parts of the pressing pins 6 abut on the upper surface 2u of the cylinder block 2. The pressing force applied to the cylinder block 2 is set to the value capable of surely crushing the blow hole K, etc., on the surface layer of the cylinder block 2. The surface of a casting can be pressed by a rolling-contact means. Thus, the casting can be prevented from being broken and deformed.
