Abstract
The invention discloses a flange expanding die which comprises an upper die plate (1), expanding female dies (3), flanging female dies (4), guide posts (5), a lower die plate (6), fixing plates (7) and an expanding male die (8), wherein the guide posts (5) are mounted between the upper die plate (1) and the lower die plate (6); the fixing plates (7) and the expanding male die (8) are mounted on the lower die plate (6); the expanding male die (8) is mounted between the fixing plates (7); the flanging female dies (4) are mounted on the fixing plates (7) respectively; and the expanding female dies (3) are mounted at the lower end of the upper die plate (1). The flange expanding die is simple in structure and assembly, precise, long in service life, convenient to operate in the using process and accurate in positioning, so that the labor intensity is reduced and the production efficiency is improved.
Description
Technical field
The present invention relates to the swollen pattern of a kind of flange.
Background technology
In the prior art, the flange pattern complex structure that expands, service life is short, and operating difficulties in the use procedure can not accurately be located, and has therefore increased labour intensity, has reduced production efficiency, has greatly affected product quality.
Summary of the invention
The purpose of this invention is to provide the swollen pattern of a kind of flange.
The technical scheme that the present invention adopts for achieving the above object is: a kind of flange pattern that expands, comprise cope match-plate pattern (1), swollen type die (3), flange die (4), guide pillar (5), lower bolster (6), fixed head (7) and swollen type punch (8), described guide pillar (5) is installed between cope match-plate pattern (1) and the lower bolster (6), fixed head (7) and swollen type punch (8) are installed on the lower bolster (6), swollen type punch (8) is installed between the fixed head (7), flange die (4) is installed in respectively on the fixed head (7), and swollen type die (3) is installed in cope match-plate pattern (1) lower end.
Guide pin bushing (2) is installed on the described guide pillar (5).
Be provided with blank holder (9) between described swollen type die (3) and the fixed head (7).
A kind of flange of the present invention pattern that expands, Standard is simple, accurately, and long service life, in use easy to operate, therefore accurate positioning has lowered labour intensity, has improved production efficiency.
