Description

Combined die forging die Technical Field The utility model relates to the technical field of combined die forging dies, in particular to a combined die forging die. Background In the field of modern metal forming and manufacturing, a combined die forging die is used as key equipment for efficiently producing metal parts in batches, and the technical performance of the combined die forging die directly influences the product quality and the production efficiency. However, there is a significant technical limitation in current commercial flow-through modular die forging dies, namely, imbalances and imperfections in the design of the heat dissipating system. Specifically, in the existing mold design, the cooling system is mainly concentrated on the lower mold part, and the effective heat dissipation of the lower mold is realized by arranging a waterway channel inside the lower mold base and connecting an external cooling pipeline. In sharp contrast, the cooling system design of the upper mold part is significantly inadequate. Because the upper die needs frequent lifting movement and is directly connected with a hydraulic system or a mechanical pressure system, a stable and reliable cooling pipeline system is difficult to set in the upper die part in the traditional design. This imbalance in heat dissipation capability results in the upper die temperature being significantly higher than the lower die during continuous forging, resulting in an overall die temperature field maldistribution. Particularly in the high-temperature forging process, the temperature of the upper die can quickly rise to a critical value, so that the thermal fatigue aging of die materials is accelerated, the temperature of the contact surface of the forging piece and the die is inconsistent, and finally the dimensional accuracy and the internal tissue uniformity of a finished product are affected. Further analysis of this technical bottleneck can be seen to initiate a series of chain reactions in actual production. Firstly, in order to prevent the upper die from being overheated and damaged, operators are forced to reduce the continuous working time, and an extra cooling waiting period is inserted in the production process, so that the production efficiency and the equipment utilization rate are obviously reduced. In a mass production scenario, this efficiency loss may translate into a significant cost increase. Secondly, the excessive upper die temperature accelerates the degradation of the surface treatment layer and the formation of thermal cracks of the die body, and particularly for high-precision forgings requiring fine surface quality, the reduction of the service life of the die is directly converted into more frequent die replacement and maintenance, and the downtime and maintenance cost are increased. Thirdly, the problem of inconsistent deformation of the forging caused by uneven temperature is solved, so that the consistency of products is difficult to ensure, and the allowance and difficulty of subsequent machining are increased.
