A kind of pressing process of fro hydraulic driving machinery formula powder former, specific step is as follows,

1) charging process: when upper limit oil cylinder uplink, feeding mechanism releases the molded product of forming, and former can be under Oil cylinder rising returns to always filling position；In this period, feeding mechanism can advance and carry out to powder, upper limit oil cylinder downlink When, sand off, feeding mechanism force back under the effect of curve ruler component.

2) pressure process: the decline of upper limit oil cylinder, upper trimming die tool start compressing powder, upper limit after entering former inside Cylinder piston rod, which is run to bottom dead centre compression, to be terminated；Its pressure process can be divided into following three kinds:

Upper mold precharge: upper punching can enter in former at the beginning, and before former does not decline together with upper mold, upper mold can be compressed Powder；This stage is known as precharge.

Float and pressurize: after upper mold precharge carries out, upper mold can further decline, and former is simultaneously and upper punching can be with identical Speed decline, to pressurizeing below molded product, therefore the density below molded product is got higher；This stage is pressurization of floating.

Final pressurization: the final stage of powder compression, the only pressurization of upper mold, former no longer decline；Upper mold once again at The pressurization of the upper surface of product, improves density above, this stage is known as final pressurization.

3) knockout course: press is after pressurization ends, and while upper mold rises, protection stripping tank stretches out, and guarantee has constant Power act on product；Next mould, lower two moulds start equilibrium, prevent product from generating demoulding crackle, former pulls down at this time, product Deviate from former；After product pulls down, feeding mechanism, which advances, releases product, and lower oil cylinder rises, and starts next filling movement.

Previous manufacture craft actuation time is 12-18 seconds or so, and the utility model technological action time is 7-9 seconds time, Every mould has saved 5-9 seconds time.

The utility model, for power, devises a kind of fixed journey system oil cylinder, in product compression process, piston rod with hydraulic Operation is equipped with one in the lower part for determining journey oil cylinder to bottom dead centre (in cylinder mouth pressing ring plane, forming a solid mechanical limit) Worm gear mechanism is covered, the length that screw rod stretches out is adjusted by worm gear mechanism and adjusts product height.Therefore product size is steady It is fixed, it is not influenced by oil temperature and pressure oscillation.It ensure that product high consistency.Bar mould is tiltedly carved using mechanical press Frame makes novel forming machine be provided with mechanical-moulded machine by compacting oil cylinder and demoulding oil jar, the three-shaft linkage mode of feed system Efficiency.Taking blame for others by special designing has the function of demoulding, filling and owes charging.Feed system, using uplink and downlink curve Plate feeler mechanism realizes the linkage with upper oil cylinder movement.It has installed mechanical press protection demoulding mechanism additional, has prevented from generating when demoulding and split Line.

Complete machine feature:
