摘要

Method and device for influencing the compaction quality of block making machines using impact compaction with imbalance pathogens. In machines of this type, defects in concrete compaction may have different causes, eg. As in the setting of adjustable machine parameters such as the amount of height of the bumpers relative to the baffle bars at rest. Depending on this, in the case of the main compression as a result of the rebound pulse, the magnitude of the downward oscillation amplitude may exceed the nominal amplitude which can be calculated by a significant amount of overshoot. In the subsequent upward swinging movement of the proportion of overshoot in the relaxation of the insulating springs to the next compression shock follows the time law of the mass-spring system with a significantly larger period compared to the period of the imbalance cycle. As a result, the next compression shock takes place at an unplanned unfavorable angle of rotation of the imbalances (or at a less favorable impact speed), which has an adverse effect on the compaction effect. The inventive solution provides to influence the amount of the pro rata overshoot amount by means of different equipment devices, which usually means to reduce it.
