Background
At present, for the high-speed development of modern technology, the rising of new energy sources, the requirements of high-precision equipment such as high-speed railways, new energy automobiles, numerical control machine tools and the like in China on light weight are higher and higher, the conventional multiple train enterprises and various electronic informatization industries in China develop gradually, the requirements of each enterprise on light weight aluminum alloy profiles are continuously increased, but the high-precision aluminum alloy profile die is still in a development stage, the digital transformation progress of the die structure is slower, and the production process of the aluminum profiles is mature gradually.
The aluminum profile structure is also gradually complicated by simplicity. The extrusion die with large inner rib size difference is difficult to produce, a die designer has great test, the extrusion service life of the aluminum alloy die is prolonged due to the specificity of the profile, and practice proves that the larger the inner rib size is, the closer the inner rib size is to the central part of the die, the faster the extrusion profile is, the slower the extrusion speed of the inner rib size is, the thicker the inner rib size is, the lower the extrusion speed is, the speed cannot be effectively controlled due to the conventional structure, the inconsistent profile size is caused, and the problems of deflection, twisting and the like occur. Waste of aluminum alloy material and waste of mold material. Thereby improving the production cost of extruded profile factories. Therefore, the product quality of the section bar is reduced, the number of consumable materials is greatly increased, and the economic benefit of a production enterprise is influenced.
In view of the above, a technique is required to solve the above-described problems.
