Reasonable maintenance of low-speed tablet press die is the key to improving service life

The low-speed tablet press die plays a crucial role in the quality of the tablet, such as the filling hole becomes larger, resulting in uneven punching filling, resulting in the difference in the weight of the tablets not meeting the regulations or producing cracks; The length of the punch is different, which directly affects the difference in the weight and hardness of the tablets, causing the chips, or affecting the brittleness; The punch has a bumpy edge or the punch is uneven, which affects the one-sided surface and causes cracks, sticky punching and so on
.

Therefore, in the daily management, we must pay attention to the daily maintenance, maintenance and storage of the low-speed tablet press die to ensure the quality
of our tablets.

The press die should be thoroughly cleaned before installation, and when cleaning, it should be noted that the die head should not collide with each other, and after cleaning, it is necessary to check whether there are bumps or knocking marks on the surface of the die after cleaning, and check whether the concave surface of the die sheet has a bumped notch and the size of the die sheet to avoid accidental installation
.

The installation sequence of the circular die is the middle die, the upper die, the lower die; The installation sequence of the special-shaped punch is installed together with the upper die and the middle die, pay attention; When installing, the upper punch and the middle die should be well matched, and the clearance around the area should be uniform, and then the lower punching die
should be installed.

Because the die blade part is very fragile, do not collide with each other during installation, when installing the middle mold, the inner hole of the punching disc should be cleaned and cleaned with a corner cleaner to ensure that the middle die can be installed in place; At the same time, the mid-die locking screw is locked tightly so as to avoid the loosening of the mid-die and damage the tablet press, and then check whether the punching into the mid-die hole is smooth
after the mid-die locking.

After the die is installed, it is necessary to hand drive the car for more than a week to feel whether there is a barrier phenomenon
.

Low-speed tablet press punching die to clear the car after pressing the sheet, disassemble the die, disassemble the die to be placed neatly, the die head should not collide with each other, the disassembled mold should be cleaned and inspected one by one, such as the problem of the die to be classified in time, the intact mold should be coated with anti-rust oil, placed in the mold box or mold cabinet
.

Low-speed tablet press die because of its standard and machine style is different, there are single punch die and rotary machine die
.

The stamping dies of single punching machines and rotary machines can be divided into circular dies and special-shaped dies according to the specifications, diameter size, and tablet shape
