Embodiment 1

[0046] An automatic forming mold for one-time bending of large sheet metal with multiple corners in this embodiment includes an upper mold part 100 and a lower mold part 200, wherein the upper mold part 100 includes an upper mold pressing plate 110 and two left and right punches 120 And upper die holder 150;

[0047] Specifically, as figure 1 As shown, two square grooves—installation grooves 111 are respectively provided on the left and right sides of the upper mold pressing plate 110, and a punch 120 is respectively installed in the installation grooves 111, as figure 2 As shown, a chute 121 is provided in the middle of the punch 120, and a bolt 130 is installed in the chute 121 to fix the punch 120 on the mounting groove 111. It should be noted that the width of the chute 121 is greater than the width of the nut of the bolt 130, and The nut of the bolt 130 can slide in the chute 121. In another embodiment of this embodiment, in order to prevent the bolt 130 from loosening,...

Abstract

The invention discloses a machining method for bending a large plate into a multi-edge-angle workpiece in one step, and belongs to the technical field of machining equipment. The multi-edge-angle workpiece is formed by one-step bending through an automatic forming die; the automatic forming die comprises an upper die part and a lower die part; the machining method comprises the steps that S1, theplate-shaped workpiece is placed on the upper surface of a lower die part of the automatic forming die; an upper die part descends for stamping, and when the die is closed, a male die of the upper diepart is attached to the upper surface of a workpiece to form a plurality of edges; a first female die of the lower die part is attached to the lower surface of the workpiece to form two obtuse edge angles; meanwhile, a second female die and a third female die of the lower die part are attached to the lower surface of the workpiece to form a plurality of edge angles respectively; S2, the upper diepart ascends; the male die is away from the upper surface of the workpiece; and a multi-edge-angle workpiece is obtained. By means of the machining method, the multi-edge-angle workpiece can be formed in one step.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing equipment, and more specifically relates to a processing method for one-time bending of a large plate with multi-angular workpieces. Background technique [0002] Molds are various molds and tools used in industrial production for injection molding, blow molding, extrusion, die-casting or forging forming, smelting, stamping, stretching and other methods to obtain the required products. In short, a mold is a tool used to shape an object. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the article through the change of the physical state of the formed material. The bending machine is a kind of equipment used for bending sheet materials. The bending principle is to place the workpiece on the plane of the lower die. When the upper die presses the lower die, the workpiece forms a bending angle ...
