Embodiment Construction

[0025] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0026] The flanging mold of the present invention can realize the flanging of the inner hole of the product, and can ensure that the height of the flanging is the same as the designed height, without the need for secondary processing such as cutting and grinding, thereby reducing processing procedures, improving processing efficiency, and reducing labor costs. Strength, can guarantee the quality of the product. An example of a flanging mold is Figure 1 to Figure 5 shown.

[0027] In this embodiment, the figure 1 and figure 2 The products shown are illustrated as examples, such as figure 1 and figure 2 As shown, the product in this embodiment is a conductive row 1, and there is an inner hole on the conductive row 1, and there is a flanging 2 at the inner hole, and the circular arc transition connection between the flanging 2 and the conductive row...

Abstract

The invention relates to a flanging die. The flanging die comprises an upper die and a lower die, wherein one of the upper die and the lower die is a male die, and the other one of the upper die and the lower die is a female die; a female die hole extending up and down is formed in the female die, a flanging supporting edge located at the female die hole is arranged at the front end of the femaledie, and the flanging supporting edge is used for supporting materials in the direction where the male die is located so as to perform flanging; an edge pressing structure is annularly arranged at theouter part of the front end of the male die in a sleeving manner, the edge pressing structure is provided with an edge pressing surface used for pressing the materials on the flanging supporting edge, and the male die and the edge pressing structure can relatively move in the up-down direction; an annular outer cutting edge is arranged on the outer side of the front end of the male die, an annular cutter is arranged on the inner wall of the female die in an inwards-protruding mode, an annular inner cutting edge is arranged on the inner side of the front end of the annular cutter and located behind the flanging supporting edge, and a distance equal to the height of the flanging is formed between the annular inner cutting edge and the flanging supporting edge; and the outer diameter of theannular outer cutting edge is smaller than the inner diameter of the female die and is matched with the inner diameter of the annular inner cutting edge so as to cut off the flanging of the material in a fixed-length mode.

Description

technical field [0001] The invention relates to the technical field of product forming devices, in particular to a flanging mold. Background technique [0002] At present, the requirements for product quality are increasing day by day. For products that require flanging, such as conductive bars, it is necessary to ensure both the diameter of the inner hole of the flanging and the height of the flanging. At present, the common processing method is to use ordinary flanging molds for flanging, which usually include punches, dies and binder plates. When using, put materials (such as conductive bars) that have pre-punched holes on the grooves. Match the punch, pre-punching hole and die, press the material on the die with a pressure plate, align the punch with the pre-punching hole for punching, and flang the material. [0003] However, the flanging dies in the prior art cannot control the height of the flanging. When the height of the flanging is greater than the design value, s...
