Abstract

The invention discloses a door jamb bending method, and belongs to the technical field of moulds and bending. According to the door jamb bending method, adopted bending moulds comprise a lower mould, an upper right-angled mould, an upper 45-degree mould, an upper flanging mould and an upper flattening mould. The method comprises the bending steps that materials are selected and marked out; a plurality of right-angled sections are bent out through the upper right-angled mould; a flanged protrusion is machined through the upper flanging mould; a right-angled section is bent out through the upper right-angled mould; then pre-bending is carried out through the upper 45-degree mould, finally the pre-bent corner is flattened through the upper flattening mould, and a door jamb workpiece is machined. According to the door jamb bending method, the bending moulds are reasonable in structural design, the cooperation performance of the upper moulds and the lower mould is good, the machining sequence is set reasonably, no interference phenomenon occurs in the machining process, machining efficiency is high, and the machined door jamb is tight in joint closing and good in sound insulation effect.

Description

[0001] The patent application of the present invention is a divisional application with the application number: 201410819761X. The filing date of the original application is: 2014-12-24. The name of the invention is: a door frame, a door frame bending mold and a bending method. technical field [0002] The invention relates to the technical field of molds and bending, and more specifically relates to a method for bending a door frame. Background technique [0003] 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 actua...
