Example Embodiment

[0047] Example 1

[0048] Combine figure 1 , A door frame of this embodiment, the door frame is integrally bent from a metal plate to form a cavity structure. The cavity structure consists of a first right-angle section 1-1, a second right-angle section 1-2, and a third right-angle section. 1-3, the fourth right-angle section 1-4, the flange protrusion 1-5, the fifth right-angle section 1-6, the flattening section 1-7, the transition section 1-7-1, the sixth right-angle section 1-8 And the seventh right-angle section 1-9 connected in sequence (such as figure 1 ), in which: the folding protrusion 1-5 includes three angle transition sections, the folding flat section 1-7 is an overlapping section with an included angle of 0°, and the folding flat section 1-7 passes through the transition section 1-7-1 and The sixth right-angle section 1-8 is connected, and the length of the overlapping section of the folded flat section 1-7 and the fifth right-angle section 1-6 is greater than 13.5...

Abstract

The invention discloses a door frame and a door frame bending die and bending method and belongs to the technical fields of dies and bending. The door frame bending die comprises a lower die, a right-angle upper die, a 45-degree upper die, an edge folding upper die and a flattening upper die, wherein a lower die edge folding groove of the lower die is matched with the edge folding upper die and used for bending a folded edge protrusion. A lower die pre-folding groove is matched with the 45-degree upper die and used for folding a transition section and pre-bending a flatly-folded section. A first V-shaped groove and a second V-shaped groove of the lower die are matched with the right-angle upper die. The door frame bending die is reasonable in structural design, the matching performance of the upper dies and the lower die is good, reasonable avoiding can be achieved, forming effect is good, only four upper dies are used for machining the complicated structure, and machining cost is low. The door frame bending method is reasonable in machining sequence arrangement, no interference phenomenon occurs in the machining process, machining efficiency is high, and a machined door frame is tight in closing and good in sound insulation effect.

Description

technical field [0001] The invention relates to the technical field of molds and bending, and more specifically relates to a door frame, a door frame bending mold and a bending method. 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 mo...
