Several Explanations on the Disassembly of Punching Die of Powder Compressor

Press die introduction:

According to the density of material, the die diameter of powder tablet press will change slightly, and it can be crossed. Flat punching is generally used for chewing tablets, buccal tablets, etc. Shallow concave tablets can be coated with film, deep concave tablets can be coated with sugar or film. When the weight of the tablet is larger (> 500 mg), the use of special-shaped tablets looks smaller, which is easy to accept by patients. When measuring hardness, the two ends of the long axis need to be measured. Long-term need not be unloaded after inserting clean oil preservation, short-term need not be coated with hard magnesium or talc powder. Die rusting can be lightly polished with fine sand paper, can not rub too much, otherwise it is easy to leak powder. The rust spots were removed by repeated pressing with magnesia and compressible starch.

Several disassemblies of punching die for Guangdong Ruiqi powder tablet press:

1. Disassemble upstream punch: loosen upstream punch fastening nut, you can pull out the upstream punch rod. If the fit is tight, you can pull out the upstream punch rod by clamping the upstream punch rod with hand pliers, but you should pay attention to not damaging the edge of the punch.

2. Remove the middle die: loosen the fixed screw of the middle die, screw down and punch the fixed screw, loosen the butterfly screw and loosen the gear pressing plate. Transfer the dynamic adjusting gear to make the lower punching core rod rise 10 mm, gently rotate the handwheel, so that the lower punching core rod will eject part of the middle die, take out the middle die by hand. If the middle die is closely matched in the hole, the hard top of the handwheel can not be rotated with force, so as to avoid damage to the machine parts. At this time, it is necessary to remove the middle die plate and take out the middle die.

3. Disassemble downrush: First, the fixed screw has been rotated downrush, and then turn the handwheel so that the downrush core rod rises to the Zui high position, you can use the hand to pull out the upstream punch rod. If the fit is tight, it can be clamped out by hand forceps (be careful not to damage the edge of the punch).

4. After the die is disassembled, the adjusting gear must be rotated so that the downward core rod can be withdrawn by about 10 mm. When the downward core rod is lifted to the high position of Zui by rotating the handwheel, the top of the downward core rod is not higher than the bottom of the middle die table (this step should not be ignored, so as to avoid the accident of the downward core rod and the mid-die collision when it is used again). After Zui, the fixed screw will still be pushed down and screwed up.
