Detailed Description

To facilitate understanding of those skilled in the art, the present invention will be described in further detail with reference to specific embodiments and drawings.

Referring to fig. 1, a preferred embodiment of the present invention is as follows.

A three-edge folding die comprises an upper die 1 and a lower die 2, wherein the upper die 1 is movably connected with the lower die 2, the upper die 1 comprises an upper die base 11, a male die fixing plate 12 and a male die 13 which are sequentially arranged from top to bottom, and the lower die 2 comprises a lower die base 21, a female die fixing plate 22 and a female die 23 which are sequentially arranged from bottom to top; the male die 13 comprises a pressure plate 131, and the pressure plate 131 is fixedly connected with the male die fixing plate 12; the female die 23 comprises three forming plates, the three forming plates are fixedly connected with the female die fixing plate 22, the three forming plates enclose together to form a three-side closed die cavity, and the pressing plate 131 can move in the die cavity. In the three-edge folding die of the embodiment, the male die 13 is a pressing plate 131 and is used for bending and folding a metal plate, the female die 23 is a three-surface closed die cavity enclosed by three forming plates, the metal plate is placed above the die cavity before being bent, after positioning is completed, the pressing plate 131 is pressed downwards, the pressing plate 131 is continuously pressed downwards after contacting the metal plate and extends into the die cavity, and the die cavity and the pressing plate 131 are used for bending the metal plate, so that the bending operation of the metal plate is completed. In the embodiment, the die cavity formed by three forming plates is respectively used for folding three edges of the metal plate, and then the three edges of the metal plate can be simultaneously bent by the forming press fit of the pressing plate 131, so that the bending efficiency and the bending accuracy of the metal plate are improved, and the deviation caused by multiple positioning is avoided.

It should be noted that the upper die base 11 and the punch retainer 12, and the punch 13 and the punch retainer 12 are both fixedly connected, a lower air cylinder is connected above the upper die base 11, and the lower air cylinder drives the upper die base 11 to move up and down, so that the punch 13 is pressed and reset.
