The invention discloses a machining method for a doorjamb bending die, and belongs to the technical fields of dies and bending. The machining method comprises the following steps: (1) machining a lower die, wherein the two opposite lateral surfaces of the machined lower die forms a plane structure, a first V-shaped groove and a lower die flanging groove are formed in a plane of the plane structure, and a lower die pre-bending groove and a second V-shaped groove are formed in a plane of the other side of the lower die; (2) machining a 45-degree upper die, wherein the machined 45-degree upper die consists of a 45-degree cutter handle, a 45-degree cutter body and a 45-degree cutter bit, which are sequentially arranged in the same direction; (3) machining a flanging upper die, wherein the machined flanging upper die is formed by sequentially and fixedly connecting a flanging die cutter handle, a flanging die cutter body and a flanging die head; (4) machining a right-angled upper die and a flattening upper die. According to the machining method, the machined lower die, 45-degree upper die and flanging upper die are high in hardness and machining accuracy and have low possibility of deformation.
Description
technical field [0001] The invention relates to the technical field of molds and bending, and more specifically relates to a processing method of a door frame bending mold. Background technique [0002] The bending machine mold is a tool used by the bending machine to process the forming sheet. This tool is composed of various parts. Different molds have different parts. It mainly realizes the processing of the shape of the article through the change of the physical state of the formed material. . Under the action of the pressure of the bending machine, the blank becomes a workpiece with a specific shape and size through the mutual guidance of the upper mold and the lower mold of the bending machine. In the actual production process, the enterprise will configure the lower mold with different groove angles according to the shape or size of the formed workpiece. However, with the development of the economy, the shapes of the workpieces to be bent are becoming more and more ...
