Local heating forming device for branch pipe self-pulling tee joint

The utility model relates to the technical field, and discloses a branch pipe self-pulling tee joint local heating forming device which comprises a fixing base, second hydraulic rods are installed on the inner walls of the two sides of the fixing base, a lower mold is arranged between the two second hydraulic rods, an upper mold is arranged above the lower mold, an air pump is installed at the top of the fixing base, and a pressure sensor is installed on the air pump. The output end of the air pump communicates with the abutting end of the second hydraulic rod. An upper mold and a lower mold are designed and fixedly arranged in the mold, a straight pipe groove is formed in the lower mold, and after a pipeline body enters the mold, the abutting ends of second hydraulic rods on the two sides communicate with an air pump to inject air pressure into the pipeline body, so that deformation is avoided when the pipeline is pressed, and furthermore, power supply heating wires are arranged in the molds on the upper sid
