| titleOfInvention | Density measuring method and density measuring apparatus for metal powder molded product |
| abstract | Disclosed is a density measuring device capable of accurately measuring the density of a portion of a sintered cold forged product that requires particularly mechanical strength. Thickness measurement for measuring a thickness d of a tooth tip 4a that requires mechanical strength of a gear 4 obtained by cold forging a preform preform after sintering a compression-molded molded body. And a propagation time measuring step of measuring the propagation time t of the ultrasonic wave by irradiating the tooth tip 4a of the gear 4 submerged in the water tank 10 from the ultrasonic irradiator and measuring the reflected wave. And a density calculating step for calculating the density of the tooth tip based on the wall thickness value and the propagation time, and comparing the density reference value of the entire forged molded body and the density value of the tooth tip to form the molded body. And a determination step for determining whether the product is good or bad. [Selection] Figure 4 |
