Abstract
A new facility for pressing a briquette of the battery NLC – 0.9 positive electrodes is developed.
In contrast to the existing construction the new design allows a release of compressed briquettes
without removing the matrix from the base. This emprovement is necessary to automate the process
of pressing briquettes, which is scheduled to implement at the Novosibirsk plant of radio
components "Oksid". Strength calculations were made in the course of developing the facility and
sizes of facility elements with the necessary accuracy requirements were determined. Calculations
were made based on the properties of the materials used. To obtain the necessary construction
rigidity with regard to changes in the volume of a pressed powder, an increase in the matrix height
is provided for.
