Description

TECHNICAL FIELD

[0001] The present application belongs to the field of extrusion dies, in particular to an aluminum profile extrusion die. BACKGROUND

[0002] At present, with the rapid development of modern technology and the rise of new energy, the demand for lightweight is increasing for high-precision equipment such as high-speed railway, new energy vehicles and numerical control machine tools in China. The domestic existing automobile enterprises and various electronic information industries are gradually developing, and the demand for lightweight aluminum alloy profiles is increasing. However, the high-precision aluminum alloy profile die is still in the development stage, and the digital transformation progress of the die structure is slow. With the gradual maturity of aluminum profile production process.

[0003] The structure of aluminum profile is also gradually complicated. It is difficult to produce extrusion dies with large size difference of inner ribs, which is a great test for die designers. The extrusion life of aluminum alloy dies is accelerated and deteriorated due to the particularity of the profile. Practice has proved that the larger the inner rib size, the closer to the center of the die, and the faster the extruded profile speed. The extrusion speed of the inner rib with small size is slower. It is difficult for ordinary dies with conventional structure to slow down the extrusion speed of the profile with large inner rib size. The speed cannot be effectively controlled, resulting in inconsistent profile size, deflection, twisting and other problems. The waste of aluminum alloy material and the waste of die material increase the production cost of the extruded profile manufacturer. This not only reduces the product quality of the profile, but also greatly increases the consumption of materials, affecting the economic benefits of the production enterprise.

[0004] In view of the above situation, a technical solution is needed to solve the above problems. SUMMARY

[0008] The working surface I and the working surface II are parallel to each other.

[0009] The flow resistance platform is also provided with an adjustment plane.

[0010] The included angle between the working inclined surface and the adjustment plane is 15°-30°.
