When the utility model is used, the process action mainly comprises the following four steps:

the method comprises the following steps that firstly, a powder weighing device is used for weighing the powder quantity of a product to be pressed once, powder with poor flowability is put into a bin, a stirring motor is started to stir, a spiral conveying mechanism is started to convey the powder falling from the bin into a vibration bin, an electronic induction scale senses that the weight in the vibration bin reaches a set weight, a signal is sent to a control console (the utility model discloses a control console is installed on one side of a hydraulic machine in a design mode and used for controlling the whole equipment to act, and belongs to the prior art), and the control console gives an instruction to enable the spiral conveyor to stop conveying; for the purpose of stirring, the stirring paddle and the scraping paddle have the further effect of preventing powder at the discharge hole of the storage bin from being blocked in order to prevent the powder from not flowing and increase the fluidity of the powder; the utility model discloses a multistation designs three title powder device and operates simultaneously.

Secondly, the weighed powder is put into a material box of a feeding device, a feeding cylinder controls the whole feeding box to be positioned in a female die and ensures that three material boxes are respectively and correspondingly arranged below each vibration material box one by one, after the feeding cylinder is in place, a cam motor of a cam rotating mechanism drives a cam to rotate, the cam rotates to act on a material box lug on one side of each vibration material box, so that a rotation right-angle hopper of each vibration material box can be rotated and opened, the material in the hopper can fall down and just fall into the material box of the feeding box, the material cannot effectively fall off once due to poor flowability of the powder, when the cam rotates, the material box lug is not acted, the rotation right-angle hopper can be closed, the process of instant closing is carried out, the rotation right-angle hopper can collide with a vertical plate to vibrate, the powder with poor flowability falls, meanwhile, a proximity switch can sense that the material box lug on the other side is close to give an instruction to enable the cam motor to continue rotating, make rotatory right angle hopper open once more and close, repeat above-mentioned action many times to ensure that the powder falls cleanly, the material loading is tentatively accomplished, and the product of processing just is unlikely to few material like this, the unqualified problem of quality.

Step three, a process for adding powder in the feeding box into the female die comprises the following steps: before the feeding is started, the main cylinder drives the upper movable beam and the upper punch to be located in the upper limit device, the two lower floating cylinders drive the lower movable beam and the female die to be located at the lower limit position, the lower central cylinder drives the three core rods to be located at the lower limit position in the lower punch, and at the moment, the upper opening of the female die, the lower punch and the upper end face of the core rods are aligned to be certain.

The feeding box sends the powder to a die of a hydraulic press, the feeding cylinder pushes the material box body to move forward between guide rails, the roller pressing plate presses the roller downwards, the problem of shaking and material leakage in the feeding process of the material box body is prevented, when the material box is positioned above a female die and stops moving forward, the lower end discharge port of three material boxes and three material grooves in the female die are in one-to-one correspondence is ensured, the air cylinder inside the feeding box moves to push a gate to stretch forwards to open the lower end discharge port of the material box, discharging is carried out, the vibrator starts vibrating, the material box vibrates, the powder can be discharged and finished, no residual material is left in the material box, after discharging is finished, the vibrator stops, the air cylinder controls the gate to withdraw and close the discharge port of the material box, the feeding cylinder drives the feeding box to return integrally, and the next material receiving and feeding process is carried out.

In the discharging process, the two lower floating cylinders push the lower movable beam to float and rise to form suction charging, so that no powder is sprayed out, and the height of the powder in the female die after charging is lower than the upper opening of the female die.

Step four, product pressing and demolding: the main cylinder drives the upper movable beam and the upper punch to move downwards, the upper punch moves downwards to enter the upper opening of the female die and then is sealed, powder cannot be impacted to fly out due to the fact that the height of the powder is lower than that of the female die, and meanwhile the magnetizing coils on the two sides are electrified, so that the powder is arranged in an ordered direction under the action of electromagnetic fields on the two sides. The upper punch continues to descend under the action of the main cylinder to punch powder, and the lower floating cylinder drives the lower movable beam to descend, so that the female die floats downwards. The lower punch is fixed, but the female die floats downwards, and the lower punch moves upwards relative to the female die, so that bidirectional floating pressing of the upper punch and the lower punch is realized, after the upper punch and the female die move downwards to a set pressing position, pressure maintaining is started, after pressure maintaining is finished, pressure is released, pressing stress is released, after pressure releasing is finished, the lower central cylinder drives the core rod to move downwards, core rod core pulling and demolding are realized, and internal stress of a product can be continuously released. And then the floating cylinder returns to drive the lower movable beam and the female die to move downwards, so that the demolding is protected, and the product is separated from the upper punch and the lower punch. And finally, the main cylinder returns to drive the upper movable beam and the upper punch to move upwards to demould and leave the product. And (5) after demolding is finished, taking out the product, and finishing a process cycle.
