摘要： PURPOSE:To prevent the generation of the buckling on a small diameter bending for a metallic pipe with thin wall by using a coil of different width in its peripheral direction as its heating coil on the case of the bending work by deforming a heated part with this heating coil. CONSTITUTION:The coil having the different coil width in its peripheral direction is used as this heating coil 24. The widthwise dimension of a heating part on the outer peripheral side to be bent of this metallic pipe 20 is made larger than the widthwise dimension of the heating part on the inner peripheral side to be bent, and also the heating temperature of its outer peripheral side to be bent of the metallic pipe 20 is made so as to be same or higher than the heating temperature of the inner peripheral side to be bent. Its outer peripheral pert to be bent becomes easy to deform due to the tensile stress on the bend-working time because its deforming resistance of the peripheral side part to be bent of the metallic pipe 20 is same or smaller than the inner peripheral side to be bent. Therefore, the wall thickness reduction is mede smaller, so the buckling can be prevented even the bending work of the metallic pipe with small diameter and thin wall thickness, because the heated width of the inner peripheral side to be bent is small and the compressed deforming amount is not necessary to be increased so as to make the wall thickness reduction of the outer peripheral side to be bent smaller.

摘要： PURPOSE:To eliminate any damage at the time of manufacturing and to improve durability and heat insulating property at the time of using by forming a porous thermal-spraying layer hang high heat resistance and acid resistance and low heat conductivity composed of metal powder as cast-in on inner wall of an exhaust port. CONSTITUTION:As the porous thermal-spraying layer 4 formed on the inner wall of the exhaust part is composed of the metal powder or the metal powder and ceramic powder, the thermal-spraying layer 4 has elongation property together with the heat insulating property at the same as or more than the ceramic. Therefore, even if stress caused by heat shock and heat fatigue is acted, as the stress is relaxed by deforming, this has excellent durability without developing any damage of crack, etc.

摘要： PURPOSE: To suppress temperature rise on the surface of work thus to increase the surface compression residual stress effective for improving the fatigue strength of work by injecting shot grains toward the work while at the sametime blowing the cooling air continuously to the surface of the work.
CONSTITUTION: An impeller type shot peening machine 1 will rotate continuously to inject shot grains 9 continuously through a slit 2 toward a rotating work 5. Upon collision of the shot grains 9 against the surface of work 5, the temperature on the surface of the work 5 will increase to lower the compressive residual stress near the surface of the work 5. Here, cooling air is blown continuously through the nozzle 8 of cooling machin 6 toward the surface of the work 5 thus to cool the surface of work 5 immediately. Consequently, lowering of the residual stress is suppressed to increase the surface compressive residual stress effective for the improvement of fatigue strength resulting in improvement of the fatigue strength when compared with conventional one.

摘要： PURPOSE: To heat the entire rugged surface uniformly and perform uniform hardening by forming a high frequency heating coil into the shape that a part thereof corresponding to a projecting part copies the projecting part axially and the other part copies the same circumferentially.
CONSTITUTION: Partial shapes of a high frequency heating coil 1 corresponding to the projecting part 2a of a shaft 2 having rugged parts are formed into the shape wherein one part has the shape copying the projecting part aixially like a copying part 1a and the other copies the same circumferentially like a copying part 1b. High frequency electricity of a relatively low frequency (≤20kHz) is conducted to this coil 1, whereby the shaft is heated. By this method, the part where offsetting of magnetic fluxes is produced and the part where it is not are produced, and the heating of the projecting part is accomplished in the same manner as for the other parts, whereby the entire part is uniformly heated.

摘要： PURPOSE:To simply detect the polishing capacity of a chemical polishing solution with high accuracy by bringing a first electrode part composed of a hardly soluble substance whose dissolving speed in the chemical polishing solution is marked low as compared with a material to be treated into contact with the chemical polishing solution to impart a minute current to said electrode part. CONSTITUTION:A first electrode part 12 composed of a hardly soluble substance whose dissolving speed in a chemical polishing solution 20 whose chemical polishing capacity must be measured is markedly low as compared with a material to be treated is brought into contact with the chemical polishing solution 20 to impact a minute current to the first electrode part. At this time, since the first electrode part 12 is composed of the hardly soluble substance whose dissolving speed in the chemical polishing solution 20 is markedly low as compared with the material to be treated, the accurate quantity of the state corresponding to the polishing capacity of the chemical polishing solution 20 is generated in the first electrode part 12. Subsequently, by calculating the quantity of chemical polishing force showing the chemical polishing capacity of the chemical polishing solution 20 from the obtained quantity of state by a chemical polishing force quantity calculating means 18, the polishing capacity of the chemical polishing solution 20 can be simply detected with high accuracy.

摘要： PURPOSE:To facilitate the stress peening of a pin fillet part by projecting shot grains to a crankshaft as a whole while rotating said crankshaft under a tensile load in its axial direction. CONSTITUTION:A crankshaft 10 the front end 11 of which is installed on a supported member 25 via a bolt 21 and the rear end 12 of which is installed on a base plate 14 via a holding member 13, is subjected to a tensile load with a holding member 23 being pulled in the B direction by means of an actuator 33 and, in this condition, shot grains are projected to the crankshaft 10 from shot grain projecting devices 41, 42 while rotating it by a motor 15. Thereby, tensile stress is generated in the pin fillet part 3 of the crankshaft 10, and the shot grains hit with the whole pin fillet parts 3 due to rotation, giving stress peening. Thus, stress peening can be easily given to the pin fillet parts.
