Specific embodiment
The present invention includes the lower die 4 that upper mold 5 and the upper mold 5 are interlocked；The joint of the upper mold 5 and the lower die 4
It is provided with the symbol shape chamber 15 of the oval end of accommodating pipe fitting 13；Connect inside the symbol shape chamber 15 with the oval end of the pipe fitting 13
It meets place and is equipped with symbol shape valve 11 annular in shape, 11 rear end of symbol shape valve is equipped with locating piece 2.
The bottom of the lower template 4 is equipped with platform board 14；The platform board 14 is equipped with swollen device 1, and extends
The pipe fitting bracket 3 of the platform board.
Hydraulic cylinder 6 that the swollen device 1 includes, is socketed in institute at the oblique cone 8 being connected with the hydraulic stem of the hydraulic cylinder 6
State the first guide pad 9 outside oblique cone 8, with first guide pad 9 be set side by side and be socketed in outside the oblique cone 8 second
Guide pad 10, and it is socketed in the molding valve 12 at the 8 variable diameter end of oblique cone.
The oblique cone 8 is freely twitched in the molding valve 12.
The molding valve 12 passes through the locating piece 2 and protrudes into the symbol shape chamber 15, is equipped with back inside the molding valve 12
Play salient point 16.
Application method of the invention is as follows:
Fixed pipe fitting
Pipe fitting 13 is placed on bracket 3, the oval end of pipe fitting 13 is placed in lower die 4, enables the symbol shape valve in symbol shape chamber 15
11 are close to locating piece 2.
Hydraulic press molding
Upper mold 5 with symbol shape is closed with the conjunction of lower die 4, drives the hydraulic system of hydraulic press to give hydraulic cylinder 6 oiling, hydraulic cylinder
6 hydraulic stem ejection drives link block 7, and link block 7 drives oblique cone 8 to slide in the first guide pad 9 and the second guide pad 10, this
When oblique cone 8 by form valve 12 on rebound salient point 16 bulge, complete swollen salient point.
