Description

Hydraulic compaction control device Technical Field The utility model relates to a hydraulic device, in particular to a hydraulic compaction control device. Background The hydraulic compaction device is widely applied to the fields of material molding, powder metallurgy, composite material processing and the like. In the prior art, a traditional hydraulic compaction device mostly adopts a single upper hydraulic driving structure, namely, a single hydraulic cylinder is used for pressing in one direction from the upper part of the device, so that compacted materials are forced to be pressed into a die cavity. However, such unidirectional compaction has significant drawbacks in practical applications: firstly, the single downward pressing is easy to cause uneven pressure distribution, and particularly when materials with high viscosity or poor fluidity are processed, single-side pressure is difficult to be uniformly transmitted to each area of the materials, so that the density difference in the interior of a finished product is large, the stress concentration and rebound phenomena are easy to occur, and the dimensional accuracy and mechanical property of the product are influenced. Secondly, in the compaction process, the air in the materials cannot be effectively discharged, and the active heat dissipation design is lacking, so that the temperature of equipment and materials is rapidly increased during continuous operation, the risk of oxidization or thermal deformation of the materials is increased, the efficiency of a hydraulic system is possibly reduced due to overheating, and the service life of key parts is shortened. In addition, the traditional device is for adapting to the frequent change mould of different thickness materials or adjustment pressure head stroke, and complex operation and inefficiency often need. Although some of the improved designs attempt to improve compaction uniformity by adding guide rods or optimizing the mold structure, the above-mentioned problems have not been fundamentally solved due to the limitations of unidirectional pressure application modes and lack of heat dissipation mechanisms.
