A device for extruding a branch pipe on a pipeline is characterized by comprising an upper die (1), a core rod (2), a punch (3), a cushion block (4) and a guide hole (5), branch pipe blind holes are distributed in the upper die (1), the size of the branch pipe blind holes is consistent with the overall size of the branch pipe preformed on the pipeline, and the distance between the branch pipe blind holes is consistent with the distance of the branch pipe preformed on the pipeline; grooves for fixing the punches (3) are machined in the core rod (2), and the distance between the grooves is consistent with the distance between the branch pipe holes. The forming die is simple in structure and beneficial to implementation, ensures that the height, the wall thickness and the branch pipe distribution of the formed branch pipe meet the requirements of drawings and technical conditions by reasonably designing the die and the forming process, improves the overall performance of a product, and improves the production be
