This is that a kind of the proof through reality makes all effective ways of even denser of charging, and is called forming machine punishment in advance function.
When the die charging finishes, when upper trimming die begins decline and enters matrix cavity, because impulse force tends to make the powder around the material top, chamber to spray out because of entering of upper trimming die, this phenomenon is tiny at some particle of compacting, during the powder of very light weight especially obviously (as some electronic ceramic powders, brush carbon dust etc.).This situation occurs the powder amount in the chamber is reduced, the parts density after compacting is finished just can not reach the quality standard of design.The way of its solution is before upper trimming die enters matrix cavity, make die lifting certain altitude equally, make die top form a cavity, when entering, upper trimming die just can not go out powder, after upper trimming die enters matrix cavity, die descends immediately and is returned to original normal operation position, and this process efficiently solves the problem of spraying powder, and what this process was called forming machine owes to expect function.
Two problems that exist in the above-described pressing process, have only die just can solve well in distance of reasonable time lifting, such function is also arranged on the import forming machines such as former Japan, but all fixing design major diameter cylinder is realized the die lifting on the center-pole of machine intimate, limited because of the gas atmospheric pressure, must realize action by the intensifying cylinder cylinder diameter, cause mechanism bulky, in the course of the work, the action of huge cylinder also causes very big operating noise.
