The invention discloses a magnetic wave instrument magnetic core forming machine which comprises a heat treating forming groove frame combination device for a rod-shaped magnetic core, a lifting column device, a magnetic core tape winding machine magnetic core tape coating fluid container groove, a hot-air drying device and the like. The heat treating forming groove frame combination device for the road-shaped magnetic core is composed of a straight-groove-shaped magnetic core forming groove frame, a pressing plate and a forming groove combination device. The rod-shaped magnetic core is located in a straight groove and pressed tightly by the pressing plate and the combination device, wherein the width of the pressing plate is same as that of the straight groove. Moreover, the magnetic wave instrument magnetic core forming machine comprises a rotating device, an alignment clamping device, a submerged rolling shaft and a raw material rolling shaft support. The magnetic core tape winding machine magnetic core tape coating fluid container groove is composed of a rectangular hexahedron type plastic container groove, wherein the lifting column device and a liquor stirrer are installed at the bottom of the plastic container groove. The hot-air drying device is a magnetic core tape coating quick-drying device which is located above the liquor level of the magnetic core tape coating fluid container groove and fixed in the middle of a lifting column with a hot-air blower as a body.
