Operation method of the hottest small powder table

Operation method of small powder tablet press

⑴ install the upper punch: loosen the lower punch fixing screw, turn the hand wheel to raise the lower punch rod to the highest position, insert the lower punch rod into the hole of the lower punch rod (pay attention to make the notch slope of the lower punch rod align with the lower punch fastening screw, and insert it to the bottom), and finally tighten the lower punch fixing screw

⑵ install the lower punch: loosen the upper punch fastening nut, insert the upper punch rod into the hole of the upper punch rod to the bottom, clamp the hexagon at the lower part of the upper punch rod with a wrench, and tighten the upper punch fastening nut

⑶ install the middle mold: loosen the fixing screws of the middle mold, take the mold flat and put it into the hole of the middle mold bedplate, at the same time, punch it down into the hole of the middle mold, press it to the bottom, and then tighten the fixing screws of the middle mold. When placing the middle mold, pay attention to flattening the middle mold, so as not to get stuck when placing it askew and damage the hole wall

⑷ operation method of small powder tablet press: turn the handwheel by hand to make the upper punch slowly fall into the middle mold hole, observe the continuous rise of the international influence of the plastic extruder industry, and observe whether there is any collision or friction. If there is collision or friction, loosen the middle mold platen fixing screws (two), adjust the fixed position of the middle mold platen, make the upper punch enter the middle mold hole, and then tighten the middle mold platen fixing screws, The installation is qualified after such adjustment until there is no collision or friction when the upper punch enters the middle die

2. Adjustment of sheet output

turn the hand wheel to raise the lower punch to the highest position, and observe whether the lower punch surface is flush with the medium die plane (either high or low will affect the sheet output). If it is not flush, loosen the butterfly screw, loosen the gear pressing plate, and transfer the upper adjusting gear, so that the lower punch surface is torn from the medium die plane, and the direction of the cut should be aligned with the rolling direction 1, then press the pressing plate still, and tighten the butterfly screw

at this point, shake the hand wheel by hand, and run the car empty for more than ten revolutions. If the machine operates normally, you can add material for pressure test and carry out the next adjustment

3. Adjustment of filling depth (i.e. adjustment of tablet weight)

loosen the butterfly screw and loosen the gear pressing plate. Turn the lower adjusting gear to the left to raise the lower core punching rod, and the filling depth will be reduced (the weight of the tablet will be reduced). After adjustment, press the gear pressing plate and tighten the butterfly screw

4. Pressure adjustment (i.e. adjustment of tablet hardness)

loosen the locking nut of the connecting rod, rotate the upper core punch, and turn left to move the upper core punch downward, then the pressure increases and the hardness of the pressed tablet increases; On the contrary, turning to the right will reduce the pressure and the hardness of the tablets. After adjustment, use a wrench to clamp the hexagon at the lower part of the upper punch rod, and still lock the connecting rod locknut. At this point, the adjustment of the die is basically completed, and then start the motor to test more than ten pieces. Check the weight, hardness and surface finish of the pieces. If they are qualified, they can be put into production. During the production process, the quality of tablets must still be checked at any time and adjusted in time

2. Precautions for the protection of steel strand testing machine

5. Disassembly of punching die

⑴ disassembly of upper punching: loosen the upper punching fastening nut, and then pull out the upper punching rod. If the fit is tight, clamp the upper punching rod with pliers to pull it out, but pay attention not to damage the edge of the punch

⑵ disassemble the middle mold: unscrew the fixing screws of the middle mold, unscrew the lower punch fixing screw Ning, unscrew the butterfly screw, and loosen the gear pressing plate. The key point of the operation of the medium mold metallographic polishing machine is to find a way to get a large polishing rate as soon as possible. If the medium mold fits closely in the hole, do not rotate the hard top of the hand wheel forcibly, so as not to damage the machine parts. At this time, remove the middle formwork platen and then take out the middle formwork

⑶ remove the lower punch: first unscrew the lower punch fixing screw, then turn the hand wheel to raise the lower punch core rod to the highest position, and then pull out the upper punch rod by hand. If it fits closely, it can be clamped out with pliers (be careful not to damage the edge of the punch)

⑷ after the disassembly of the die, it is still necessary to turn the adjusting gear to make the lower core punching rod retreat by about 10 mm. When the hand wheel is turned to make the lower core punching rod rise to the highest position, its top is not higher than the bottom surface of the middle die platen (this step should not be ignored to avoid the collision between the lower core punching rod and the middle die when it is used again). Finally, screw in the lower punching fixing screw
