The invention relates to an explosive loading device for explosive press fitting. The device is suitable for improving the density evenness of a press fitting explosive column, improving the initial explosive loading shape and the explosive loading quality before explosive pressing, improving the penetration capacity and the armor penetration stability, in a large burst height condition, of energy gathering jet flow formed by oil perforating bullets. The device is composed of a container, a sealing block, a pull rod, a material diffusion body, a locating cover plate and an explosive scrapping plate. A pull rod in the container moves upward slowly to control explosive loading powder material flowing performance and enable the explosive material to depend on self-gravity to sink and flow into an explosive pressing die sleeve below the pull rod at even speed along through holes in the circumferential direction. Consequently, the defect that directly pouring explosive materials into the explosive press die sleeve in an uncontrolled mode at explosive pressing time obviously influences the distribution evenness of explosive column density is overcome, the purposes of the piling height uniformity of loose explosive in the die sleeve and the initial loose loaded explosive density and particle distribution uniformity are achieved, the loading quality and the density evenness of a perforation bullet explosive loading column are improved, and the requirements of perforation bullet destroy power in various conditions are met.
