The invention discloses a powder pressing formation device and belongs to the technical field of powder pressing formation. The powder pressing formation device is characterized in that a rotary workbench with inner teeth formed in the periphery of a center hole is supported on a machine base, formation lower die grooves are formed in the workbench face of the rotary workbench at the equal intervals of 120 degrees, and a funnel-shaped hopper, a quantization device, a formation upper die column connected with a piston rod and a finished product ejection and collection device are arranged at the upper positions corresponding to the formation lower die grooves respectively. The powder pressing formation device has the advantages that the formation lower die grooves at the trisection positions of the rotary workbench correspond to three working procedures of quantized loading, pressing formation and finished product collection to work simultaneously, the working efficiency is improved, product quality is improved through quantized loading and pressing formation, and automatic production is achieved through continuous work.
