Abstract
PURPOSE: To improve the production yield of nondefectives by rotating the molding blank material having been subjected to cold-pressing within a short time of the extent of not hampering the other cold-pressing stages, on the way of the cold-pressing stage of a multistep type cold-pressing machine and inspecting the presence or absence of any flaws.
CONSTITUTION: A cold-pressing machine having one more step than the required number of cold- pressing steps is prepared, and a flaw detector C consisting of a case 17 provided with a pusher 18 and a push pin 20, and a holder case 7 is installed right after the cold-pressing stage apprehensive for forming defectives, for example, right after the cold-pressing device of the 2nd-step consisting of a die 52 and a punch 62. The end face of the blank material is straightened by the die 51 and punch 61 of the 1st step, and the blank material is upset by the die 52 and punch 62 of the next cold-pressing stage. At this time, flaws are often produced in the blank material and therefore the blank material is inserted into the holder case 7, and while it is held with the push pin 20, it is rotated and the presence or absence of any flaw is detected with the flaw detector C. The defective is removed and only the nondefective is fed to the 3rd and 4th cold-pressing states, whereby the wasteful operation of cold-pressing the defective in the 3rd and 4th step cold-pressing devices is eliminated.
