A solid phase binding device and binding method with plastic-flowing hot metal plates are provided to skip the existing step for removing oxide film and improve production efficiency by pressing two thick metal plates through a forging pressure with plastic-flowing and by simultaneously removing oxide film on distal end or superposition of the plates through fine solid phase binding and operation of a saving metal mold. A solid phase binding device with plastic-flowing two metal plates comprises an upper binding metal mold(7), a lower binding metal mold(8), an upper clamp(9), a lower clamp(10), and a saving metal mold(11). To give a binding load to two superposed hot metal plates(1), the upper binding metal mold is disposed up to distal end surface of the left-upper one(2) of the two metal plates, whereas the lower binding metal mold supports distal end surface of the right-lower one(3) of the two metal plates. When the upper metal plate slides and moves downward, the superposed metal plates are pressed by a contact of the upper metal plate transferring a compressive load to the superposed plates. A trumpet-shaped entrance(19) is installed at each inlet of the binding metal molds to easily insert the two hot plates into the binding metal molds. A male profile of the upper binding metal mold is engaged with a female profile of the lower clamp to accurately fit position of the binding part. A female profile of the lower binding metal mold is engaged with a male profile of the upper clamp to prevent the plates from spreading in a width. A clamping oil pressure cylinder of the upper binding metal mold is connected with the lower clamp through a cylinder rod to clamp the plates between the engaged metal mold and the clamp. The other clamping oil pressure cylinder of the lower binding metal mold is connected with the upper clamp through the other cylinder rod. A step is installed on each edge of the upper and lower clamps to insert the saving metal mold. A plurality of holes are punched left and right through the upper and lower clamps to insert supporting units and springs for supporting the saving metal mold. The saving metal mold inserted into each edge of the upper and lower clamps contacted on the binding metal molds comprises a knife edge for removing oxide film formed on surface of the metal plates and a saving residue storing space installed in front of the knife edge. When the two plates are inserted simultaneously in a protruded state of the saving metal mold by tension of an excessive metal expelling spring(15) installed at rear side of the saving metal mold, the oxide film is removed by saving-cutting each surface of the opposite plates through the shrinking spring and the knife edge. A trapezoidal curved slope is installed on the saving metal mold to form an excessive metal storing space(14) which is surrounded by the curved slope of the saving metal mold, the clamp surface, and the metal plate ending surface to occupy a half volume of the metal plates superposition for receiving the excessive metal caused by spreading plates and the oxide film. As the edge of the binding metal mold contacts on the edge of the saving metal mold to finish binding, a discharge of the excessive metal is finished at the same time. When the upper and lower binding metal molds are separated, the excessive metal and the oxide film filling the excessive metal storing space are discharged through the resilient force of the spring installed at rear side of the saving metal mold.
