Description
Technical field
The utility model relates to a kind of abrasive wheel forming mould.
Background technology
As shown in Figure 6 and referring to Fig. 7; Tradition abrasive wheel forming mould comprises lower bolster 5, abrasive wheel forming stem stem 8, cope match-plate pattern 18 and mould circle 21; Cope match-plate pattern 18 is located at mould circle inner chamber top, and lower bolster 5 is located at mould circle inner chamber bottom, and cope match-plate pattern 18 is respectively equipped with stem stem installing hole 17 with lower bolster 5 centers; Abrasive wheel forming stem stem 8 two ends are sleeved on the stem stem installing hole 17 of cope match-plate pattern 18 and lower bolster 5; Be placed with upper surface on the said cope match-plate pattern 18 and exceed the trim ring 26 of said mould circle 21, the top of said trim ring 26 is corresponding to the pressure head, and the external diameter of said pressure head 24 is greater than the internal diameter of said mould circle 21.
,, comprise the steps: during the moulding of emery wheel blank to shown in Figure 10 like Fig. 7
The first step is as shown in Figure 7; Place cushion block 20 in mould circle 21 lower edges, abrasive wheel forming stem stem 8 is fixed on the stem stem installing hole of lower bolster, abrasive material is put into abrasive wheel forming die cavity 9; Abrasive material is stirred and the equating arrangement; Cover template 18 then, on cope match-plate pattern 18, place trim ring 26 again, the upper surface of said trim ring 26 exceeds said mould circle 21.
Second step is as shown in Figure 8, and mould is pushed forcing press, and pressure head 24 presses down said trim ring 26; Said trim ring 26 promotes said cope match-plate pattern 18 and moves downward; Be positioned at abrasive material downward compacting from top of abrasive wheel forming die cavity 9, when the pressure head is pressed in 21 last times of said mould circle for 24 times, pressure head 24 no longer moves downward; Press on the abrasive material and finish, this moment, the density of abrasive material after pressure forming on abrasive wheel forming die cavity 9 tops was bigger.
The 3rd step is as shown in Figure 9, lifts pressure head 24, and cushion block 20 is removed, and has raised mould circle 21 because of cushion block 20, and mould circle 21 has had downward space.
The 4th step is shown in figure 10; The starting pressure machine; Pressure head, mould circle 21, trim ring 26 and cope match-plate pattern 18 move downward together; Lower bolster 5 moves upward with respect to mould circle 21, then compacting the abrasive material of abrasive wheel forming die cavity 9 bottoms, make that the emery wheel blank compacted density in the abrasive wheel forming die cavity 9 is even.
The 5th step moved on to mould on the dedicated, carried out stripping operation; At first manual work is beaten abrasive wheel forming stem stem 8 and mould circle 21 respectively and is gone out from cope match-plate pattern, emery wheel blank and lower bolster; Remove cope match-plate pattern then, place emery wheel blank supporting plate, again the emery wheel blank is overturn; Remove lower bolster, the emery wheel blank is placed on the moulding of promptly accomplishing the emery wheel blank on the emery wheel blank storage rack together with emery wheel blank supporting plate.
The shortcoming of prior art is:
1. the forcing press in forming process, all the other operations are all artificial to be accomplished, and complex steps is complicated, and production efficiency is low, is inappropriate for production in enormous quantities.
2. produce bigger friction at knockout course medium plain emery wheel blank outer surface and mould circle 21 inner surfaces, mould circle inner surface very easily weares and teares, and has had a strong impact on the service life of mould circle 21, and the size of emery wheel blank is changed.
3. need manual work to beat at knockout course medium plain emery wheel moulding stem stem 8 and go out, consume operating personnel's muscle power in a large number, production efficiency is lower.
4. the security of emery wheel blank moulding is relatively poor.
