The mould bases is connected to by hexagon socket countersunk flat cap head screw 30 on firm banking 11 above vibrating mechanism；The mould
Frame is intermediate guiding mould bases, and upper and lower die holder is oriented to by the way of guide post 28 and guide sleeve 29, and two guide posts 28 are mounted on mold
It, can only a direction feeding on line of symmetry；29 endoporus of guide sleeve has oil storage tank, endoporus and guide post 28 to be slidably matched；Outside guide sleeve 29
Using interference fit, the lower part of guide post 28 uses interference with the guide pillar hole of lower die holder fixed plate 12 for diameter and upper die holder fixed plate 20
Cooperation；
Inventive die uses the inverted structure of Drawing Die, punch-pin 15 to be pressed on convex mould pad 13, passes through unloading bolt 19
It is located in lower die holder fixed plate 12；Holding pad 16 is sleeved on punch-pin 15, in the upper surface of punch retainer 14, passes through unloading bolt
19 and Rectangular Spring 18 ensure positional precision；Cavity plate 21 realizes limit by the first positioning screw 17 being fixed on holding pad 16
Position.
Cavity plate 21 is monoblock type plate shape cavity plate, is fixed in upper die holder fixed plate 20 by soket head cap screw 22, and use
Positioning pin 26 positions；Backform block 27 is placed in cavity plate 21；Die shank 23, which is sleeved on, to be beaten on bar 24, is fixed on by the second positioning screw 25
In upper die holder fixed plate 20, die shank 23 is connect with 24 interference of bar is played, and beating 24 bottom of bar has screw thread, is connect with backform block 27；Die shank
23 upper die holder fixed plates 20 are fixed on press ram, while mold center being made to pass through the Center of Pressure of sliding block；
The hydraulic motor 5 is used as power source, is supported by two rolling bearings 8, motor fixing plate 6 and end cap 10 are liquid
Pressure motor 5 is fixed in motor fixing seat 2, and end cap 10 is connect with motor fixing seat 2 using interference；Lower die holder fixed plate 12 with
Backing plate 31 is added between motor fixing seat 2, with the shape of die holder fixed plate 12 under the influence of preventing to generate shadow to part accuracy
It rings.Washer 7 can be set between motor fixing plate 6 and rolling bearing 8；Hydraulic motor 5 is connect with the key 4 of eccentric wheel 1；Jacking block 3
Upper end connects punch-pin 15, and lower end is contacted with eccentric wheel 1, and vibration is transmitted to punch-pin 15 from eccentric wheel 1；Hydraulic motor 5 drives partially
