Concrete block mfg. method - uses press with controlled vibration movement which has spring loaded stops controlled by cylinder to stop process

摘要

The mfg. method of concrete blocks, includes controlled vibration of concrete mixture. Spring loaded stops are controlled by adjusting cylinders, which stop the vibrating action, enabling the ejection of the concrete blocks without e.g. tearing. The press for concrete blocks mfg., includes a table (5) and two contact stops (21) cooperating with contact stops (22), which are connected to die (7) top. The die has a blind bore in which the bottom of pressure spring rests.
