The solution to avoid the shading on the surface of aluminum profile caused by the design defects of the shunt mold
Release Time:
2020-11-02
The surface shadow of aluminum profile caused by improper shunt design can be avoided by improving the design method of extrusion shunt die (PKC7003 example)
The surface shadow of aluminum profile caused by improper shunt design can be avoided by improving the design method of extrusion shunt die (PKC7003 example):
A. Adjust the size of the shunt hole and the size of the core head empty knife and the position of the die bridge; b. Adjust the transition of the working belt; see the original design drawings A and C; the adjusted design drawings B and D.
Adjust the size of the shunt hole, the size of the core blank and the position of the die bridge
Improved shunt mold design drawing
It can be seen from the figure that the left and right shunt holes are enlarged after the upper die of the splitter die is improved, the die bridge is not placed at the junction of the splitter and the flat die, the left and right core head empty tool positions are enlarged, and the core head sharp corner position lifts the working belt About 0.5mm, the discharge surface of the aluminum extrusion die is equipped with a working belt to reduce friction, increase the feed at the sharp points and corners of the profile, ensure the balance of the feed and the adequate organization, and effectively avoid the generation of shadows;
The lower die of the extruding splitter mold changes the distribution of the working belt. There is no transition in the working belt of the "T" position, and the drop of the working belt is reduced. The value is smooth and smooth. In order to reduce the flow velocity of the flat mold part, the flat mold part is electrolytically eroded 2mm deep The pits make the flow rate at the junction more uniform, and the dark shadow after the surface treatment of the profile is greatly reduced; secondly, if the "T"-position flat mold part needs to be transitioned, it should be a certain distance from the shunt part, and the small mold core is 1~1.5 mm, the large mold core is 2~3mm, and the working band value should be within 2mm of the wall thickness as far as possible. Also, please note that when the mold core is too small, the upper and lower necks of the upper mold should be higher than the lower mold. The working belt is 1.5mm to reduce the impact of the upper and lower die working belt misalignment caused by the elastic deformation of the upper die caused by extrusion.
Used to process electrodes with high and low points. After processing, remove burrs and sharp corners, so that they are not less than R3 arc transition to avoid sharp corners after processing;
