The invention discloses a processing technology of a hinge shaft in an iron door hinge. The processing technology is characterized by comprising the following steps that cutting is carried out, wherein a round steel material is straightened and is conveyed into a corresponding device and cut into a blank with a required size; first section shaping is carried out, wherein the blank is conveyed intoa first section shaping mold and extruded, so that the shape of the blank is extruded into the shape of the hinge shaft; stretching and guiding are carried out, wherein the blank is conveyed into a stretching and guiding mold, center axial extrusion is carried out on the blank so that a center hole can be obtained through extrusion in the center of the blank, meanwhile the extruded portion material of the center overflows in the radial direction, and the axial size and the radial size of the blank are increased; second section shaping is carried out, wherein the blank is conveyed into a second section shaping mold and extruded, and the shape of the blank is finished; stretching is carried out, wherein the blank is extruded, and the axial size and the radial size of the blank are further increased; and third section shaping is carried out, wherein the blank is conveyed into a third section shaping mold and is shaped, and processing is completed. By the adoption of the processing technology, the consumable and the production cost are reduced.
本发明公开了一种铁门铰链中铰链轴的加工工艺，其特征在于包括以下步骤：裁剪，将圆钢材料拉直并送入相应装置裁成所需尺寸的胚料；一段整形，将胚料送入一段整形模具挤压，使胚料的外形被挤压成铰链轴的外形；拉伸导向，将胚料送入拉伸导向模具，对胚料进行中心轴向挤压，以在胚料的中心挤压出一中心孔，同时中心被挤压部位材料径向外溢，使得胚料轴向以及径向尺寸增加；二段整形，将胚料送入二段整形模具挤压，对胚料的外形进行修整；拉伸，挤压胚料，使得胚料的轴向和径向尺寸进一步增加；三段整形，将胚料送入三段整形模具进行整形，完成加工。本发明降低了耗材以及生产成本。
