Description

Liquid die forging filter residue type liquid flow buffer control tool

Technical Field

The utility model belongs to the technical field of tracked vehicle, a liquid forging filter residue formula liquid flow buffer control ware is related to.

Background

At present, the production mode of liquid die forging has the advantages of less investment of production equipment, less average energy consumption of products, higher production efficiency and suitability for batch production. The production flow of liquid die forging mainly comprises two parts of metal smelting and pressure forming. The control of the impurity content in the metal smelting process is a prerequisite for influencing the product quality, and the mixing-in of impurities in the pressure forming process also has a decisive influence on the quality. The production process has a very important influence on the quality of the product, and the improvement of the tooling also has a non-trivial role on the quality of the product.

In the pressurizing and forming process of the wheel disc of the tracked vehicle, when liquid aluminum at high temperature flows into the mold, a small amount of aluminum liquid can be contacted with the wear-resisting ring at lower temperature and is solidified first, and the subsequently poured aluminum liquid cannot be tightly combined together to form an interlayer. When molten aluminum flows into a mold, the molten aluminum splashes at an excessively high speed, and impurities are easily generated, so that the mechanical performance of a product is reduced, the production cost is increased, and a large amount of aluminum ingot raw materials and energy are consumed.

At present, when liquid aluminum liquid enters a lower die in a pressurizing and forming process of the wheel disc assembly for the unit tracked vehicle, the conditions of splashing, cold shut, slag inclusion and the like are easy to occur, so that the mechanical performance of a product is reduced, the product percent of pass is reduced, the production cost is increased, and a large amount of energy and aluminum raw materials are consumed.
