Detailed Description

The following describes the present invention with reference to the accompanying drawings.

Referring to fig. 1 to 13, the utility model discloses an air bearing foil floating forming device of this application includes: the device comprises an upper template 1, an upper die 6, a lower die holder 5, a lower die 4 and a guide pillar 2; the lower die base 5 is U-shaped, a first hole 10 and a second guide pillar hole 11 are respectively formed in the first side along the horizontal transverse direction and the vertical direction, a first threaded hole 12 is formed above the first hole 10 and connected with the adjusting screw 3, and the second side is obtained by mirroring the first side; the lower die 4 transversely penetrates through a first hole 10 of the lower die base 5, is detachable and is axially positioned and circumferentially rotated by the adjusting screw 3; the lower half part of the guide post 2 is provided with a concave clamping ring groove 22, and the guide post 2 is inserted into the guide post hole II 11 and fixed through a clamping ring.

A first guide post hole 15, a bolt mounting hole 16 and a second round hole 18 are formed in the first side of the upper template 1, and the second side is obtained by mirroring the first side; a third threaded hole 19 and a third round hole 20 are formed in the first side of the upper die 6, and the second side is obtained by mirroring the first side; the upper die 6 is fixedly connected with a bolt mounting hole 16 on the upper die plate 1 through a bolt 7 and a third threaded hole 19, and the cylindrical pin 8 transversely penetrates through a second round hole 18 on the upper die plate 1 and a third round hole 20 on the upper die 6 for limiting.

The upper die plate 1 is in sliding connection with the guide pillar 2 through the first guide pillar hole 15, the center of the upper die plate 1 is provided with a second threaded hole 17 which is connected with a push rod of the device, and the push rod pushes the upper die plate 1 to slide up and down along the guide pillar 2 during operation.
