1. Use the original manufacturer's extrusion die, spring, sleeve and pressing head.
2. After the extrusion die is installed, it will slowly extend the piston during no-load operation to allow the top indenter to enter the inner hole of the extrusion die, and check the alignment between the top indenter and the extrusion die.
3. After the steel strand is cut, the section is continuously skewed to keep it tidy, and the burrs should be removed.
4. Use hand flaps to test the brittleness and hardness of the compression spring during installation.
5. It is necessary to clean the dirt of the extrusion part of the strand strand before extrusion, and apply a thin layer of anchoring agent to the surface of the inner hole of the extrusion die. Clean the spring wire remaining in the inner hole of the top pressure head to make the length of the steel strand in the extrusion sleeve longer.
6. Rotate the extrusion spring inside the steel strand. Then insert the steel strand in the hole of the extrusion die. Rotate the steel strand and the extrusion spring into the extrusion sleeve.
7. Keep the extension of the longitudinal middle line and the stranded steel wire, close the assembly to the top indenter. During the pressing process of the machine, the hand-held extrusion sleeve and the top indenter remain centered until the extrusion sleeve Clamp between the extrusion die and the top ram. The squeezing process does not stop and is completed in one time.
8. Due to the insufficient length of the steel strand, the extruded body is cut and re-extruded.
9. In order to protect the normal use of the extrusion die, a thin layer of unanchoring spirit needs to be coated in its inner hole.
10. In order to prevent its top pressure head from reaching the extrusion die and damaging it, it is necessary to release the hydraulic pressure to return to 0 after the extrusion.
11. In order to ensure the quality of the extruded body, the tensile test of the extruded body should be done at intervals.
12. Extrusion dies and extrusion rams of wearing parts should be replaced in time if they show signs of wear and affect the extrusion quality.
aluminum tube extrusion produced by Henan Chalco are widely used in electricity, machinery manufacturing, oil and gas industry, aviation industry, etc.
