Detailed Description

The present invention is described in detail with reference to the embodiments shown in the drawings, but it should be understood that these embodiments are not intended to limit the present invention, and those skilled in the art should understand that the functions, methods, or structural equivalents or substitutions made by these embodiments are within the scope of the present invention.

The flanging die shown in fig. 1-4 comprises an upper die 1, a lower die 2, an upper press plate 41 sleeved on the upper die 1, a plurality of first air cylinders 5 connected to the upper die 1, a lower press plate 42 sleeved on the lower die 2, and a plurality of second air cylinders 6 connected to the lower die 2.

The cross sections of the upper pressure plate 41 and the lower pressure plate 42 are both annular. The first cylinder 5 and the second cylinder 6 are both micro cylinders, and the models of the micro cylinders can be MAL20 × 25-500, CUJB8-4D, MAL and the like.

The device also comprises an upper extension plate 31 connected to the upper die 1, and the first air cylinder 5 is connected to the upper extension plate 31. Go up extension plate 31 and go up mould 1 formula structure as an organic whole, the sound construction is stable. The number of the first air cylinders 5 is four, and the first air cylinders are uniformly distributed on the upper pressing plate 41 at intervals in a surrounding manner, so that the upper pressing plate 41 is uniformly stressed. The upper pressure plate 41 is connected to a piston rod 51 of the first air cylinder 5, and the extension and contraction of the piston rod 51 can drive the upper pressure plate 41 to ascend and descend.

Still including connecting the lower extension board 32 on lower mould 2, second cylinder 6 is connected on lower extension board 32, lower extension board 32 and lower mould 2 formula structure as an organic whole, the sound construction is stable. The number of the second cylinders 6 is four, and the second cylinders are uniformly distributed on the lower pressing plate 42 at intervals, so that the lower pressing plate 42 is uniformly stressed. The lower pressing plate 42 is connected to a piston rod 61 of the second cylinder 6, and the extension and retraction of the piston rod 61 can drive the lower pressing plate 42 to ascend and descend.
