Title: Manufacture of rotor and hub for motor
Inventor: TAMURA TAKASHI
IPC: B23P13/00
Filed: 1988-06-27
Abstract: PURPOSE:To improve production efficiency and to prevent production of burrs by a method wherein inner and outer cylinder bodies are molded by hot forging, and after the cylinder bodies are cooled in an interference fit state, a through-hole for a motor shaft is formed in each of the bottom walls of the two cylinder bodies by a machining work. CONSTITUTION:Inner and outer cylinder bodies 14 and 15 are molded such that a billet 13 of a low density quenching solidifying metallic powder material contained in a molding die 6 and having the coefficient of thermal expansion higher than that of a magnetic material is hot-forged by a punch 10 engaged internally of a premolded inner cylinder body 12 made of a magnetic material. The inner and the outer cylinder bodies 14 and 15 are brought into an interference fit state by cooling. Thereafter, a through-hole 18 for a motor shaft is formed in each of bottom walls 16 and 17 of the inner and outer cylinder bodies 14 and 15 by a machining work. Thus, there is no need for engagement after individual molding, and production efficiency can be improved. Since formation of the through-hole 18 for a motor shaft is effected after interference fit of the inner and outer cylinder bodies 14 and 15, displacement is prevented from occurring, and since formation of the through-hole is made by a machining work burrs produced as in a blanking work is prevented from production.

Title: Manufacture of stainless steel sheet of excellent surface quality
Inventor: SUMITOMO HIDEHIKO
IPC: B21B3/02
Filed: 1989-06-23
Abstract: PURPOSE:To obtain good surface quality without the generation of uneven brightness by casting into the cast piece of thin band-like with a continuous casting machine and performing descaling by cleaning with an abrasive grain for polishing as the pretreatment of cold rolling process. CONSTITUTION:Instead of performing the descaling by pickling as the pretreatment of cold rolling process, the descaling by cleaning with the abrasive grain for polishing is performed. Intergranular corrosion groove due to the precipitation of Cr carbide which is the cause of the uneven brightness is not generated. And the ruggedness on the surface of cast piece is made further uniform by intensifying the removement of scale and it contributes to the improvement of surface nature. That method is effective to also chromium type stainless steel in addition to austenite type stainless steel. As the descaling method by cleaning with abrasive grain for polishing, liquid honing, belt grinding, grit blasting and brush containing abrasive grain, etc., are used. Thereby, uneven brightness after cold rolling isn't generated and the stainless steel sheet of good surface quality can be obtained.
