摘要：【中文】本发明涉及金属成型领域，公开了一种金属成型的方法及其装置，该包括以下步骤：S1：准备圆柱形金属坯料；S2：在所述金属坯料外侧壁缠绕n圈高强度薄带；S3：将缠绕了所述薄带的金属坯料预热到0~0.6Tm，所述Tm为所述金属坯料的熔点；S4：将所述金属坯料位置固定的同时，按照所述薄带缠绕的方向在所述薄带外圈同时持续作用切向力和指向所述金属坯料方向的径向力，所述金属坯料在所述薄带的缠绕作用下产生塑性变形，塑性变形的金属坯料进入到模具内成型成产品。与现有技术相比，本方法可以大大降低金属成型时所需的外加载荷力，使用较小的力就可实现金属塑性变形的目的。 【EN】The invention relates to the field of metal forming, and discloses a metal forming method and a metal forming device, which comprise the following steps: s1: preparing a cylindrical metal blank; s2: winding n circles of high-strength thin strips on the outer side wall of the metal blank; s3: preheating the metal blank wound with the thin strip to 0-0.6 Tm, wherein the Tm is the melting point of the metal blank; s4: and fixing the position of the metal blank, simultaneously continuously applying a tangential force and a radial force pointing to the direction of the metal blank on the outer ring of the thin strip according to the winding direction of the thin strip, wherein the metal blank generates plastic deformation under the winding action of the thin strip, and the plastic-deformed metal blank enters a die to be molded into a product. Compared with the prior art, the method can greatly reduce the external loading force required during metal forming, and can realize the purpose of metal plastic deformation by using smaller force.
