[CN 202010279194.9] Preparation method of magnesium alloy profile for vertical hydraulic press by large deformation compound extrusion
[CN 202010279194.9] A Preparation Method for Large Deformation Composite Extrusion of Magnesium Alloy Profile for Vertical Hydraulic Press Title: A Preparation Method for Large Deformation Composite Extrusion of Magnesium Alloy Profile for Vertical Hydraulic Press Application Number: CN 202010279194.9 Applicant: north university of china Application Date: 2020-4-10 Patent Type: Application for the Invention The present invention discloses a preparation method for large deformation composite extrusion of magnesium alloy profile for vertical hydraulic press, including ① blanking, ② homogenization treatment, ③ The blank and the die are heated and kept warm. ④ Apply lubricant and put the blank into the positive extrusion cavity. ⑤ Extrude the blank forward. The blank is extruded into the material storage cavity through the sizing belt. ⑥ The blank continues to flow under pressure until it contacts the bottom of the material storage cavity. The blank flows radially and gradually fills the space in the material storage cavity. During this process, the blank is upset and deformed. ⑦ It is pressed down by the punch, the billet metal begins to flow to the radial cavity extrusion opening communicated with both sides of the storage cavity, and lateral extrusion deformation occurs. When the punch stroke ends, the lateral extrusion process also ends, ⑧ demoulding. This case realizes the positive extrusion-rough-side extrusion large plastic deformation once forming, improves the variable, enriches the stress strain state, improves the organization and weakens the texture strength, effectively reduces the production process, and adapts to the market economic prospects of our country.
