Progressive die precision cold forging machining device

According to the progressive die precision cold forging machining device, a vertically-arranged insert hole is formed in the upper surface of each lower die base and located under an upper punch, and a forming gap allowing the lower portion of a material belt to be squeezed in is formed between the upper end of an insert and the inner wall of the upper end of the insert hole; a plurality of guide holes are formed in the upper surface of the lower base plate and located on the two sides of the material belt, the lower end of a guide pin capable of moving up and down is embedded into the guide holes and connected with a first elastic piece, and the upper end of the guide pin extends upwards from the upper surface of the lower base plate and is provided with a groove allowing the edge of the material belt to be embedded. Two punching male dies are installed on the upper base plate and located on the rear side of the upper punch, and the two punching male dies which are arranged at intervals in the direction perp
