Description

Technical Field

[0002] Magnesium alloy is the metal structural material with the lowest density. It has the advantages of high specific strength, high specific modulus, high damping, electromagnetic shielding, radiation resistance, good casting and cutting performance, and easy recycling. It has important application value and broad application prospects in the fields of automobiles, electronics, aviation, aerospace, etc. Magnesium alloy has very low plasticity at room temperature and its elongation is only 4% to 5%, so extrusion is the most ideal forming method for magnesium alloy sheets.

[0004] The device can guide the movement of the magnesium alloy sheet by installing anti-fracture rollers, so that the forming die head pushes the magnesium alloy sheet into the interior of the forming die to form the magnesium alloy sheet, thereby preventing large friction between the forming die and the deformation part of the magnesium alloy sheet, which may cause the magnesium alloy sheet to break and affect product quality. The installation of a discharge bracket can enable the propulsion plate to drive the material to be discharged when moving upward, thereby preventing the device from getting stuck and enhancing the use effect of the device.

When the plates are larger, the required die and push plate need to be larger, and the operation is cumbersome. When the traditional roller press is forming larger plates, it is impossible to adjust the spacing between the extrusion rollers, and thus it is impossible to control the extrusion thickness and ensure the extrusion effect.
