Machining die for coiled pipe of heat exchanger

The utility model relates to a heat exchanger coiled pipe processing mould which comprises two mould racks which are symmetrically arranged, each mould rack comprises a working table, the upper end of each working table is connected with a first mould and a second mould, and the first mould and the second mould are arranged on one side far away from the symmetry axis of each working table. The first mold and the second mold are arranged on the same axis, the axis where the first mold and the second mold are located is parallel to the symmetry axis of the workbench, the first mold is fixedly connected to the workbench, the second mold is slidably connected to the workbench, and the two symmetrically-arranged mold racks form a mold structure with a fixed position. The pipe bending operation can be carried out through the first die and the second die, meanwhile, bending can be carried out twice, the first die mainly serves as a positioning reference, the second die serves as a main operation area, simplicity and
