Embodiment 1

[0017] A φ120mm aluminum alloy cylinder body, the preparation method is a, the weight percentage of its aluminum alloy material components are Zn 7%, Mg 3%, Cu 2.4%, Mn 0.8%, Cr 0.1%, and the balance Al; b. The prepared materials are cleaned and preheated and dried. At the same time, the crucible melting furnace is preheated to increase the temperature. When the preheating temperature rises to 200℃, the surface of the material is painted with zinc oxide, silica gel, and water to prevent the crucible melting furnace Corrosion; c. Then put the Cu, Mn, Cr, Al in the dried aluminum alloy raw materials into the melting furnace to continue heating up, and when all the metals are melted and the alloy melt temperature stabilizes to 735°C, Zn and aluminum are added The 0.2% hexachloroethane of the alloy melt is refined and refined. The refining time is 10 minutes. When the temperature of the aluminum alloy melt rises to 730℃, add Mg. After the materials are all melted, remove the dross and...

Abstract

The process of making oil cylinder body and cover of aluminum alloy includes the following steps: heating in a smelting furnace the materials comprising Zn 1-8.0 wt%, Mg 1.0-5.0 wt%, Cu 0.8-2.5 wt%, Mn 0.2-1.0 wt%, Cr 0.1-0.3 wt% and Al for the rest; refining; casting in extruding and casting mold through fast closing mold, slowly applying pressure and maintaining pressure for the aluminum alloy to solidify and crystallize; and final solid solution ageing T6 heat treatment on the cast blank to obtain oil cylinder body and cover casting. The process has high material utilizing rate, high production efficiency and low production cost, and the product blank has light weight, compact and homogeneous structure and less faults.

Description

Technical field [0001] The invention relates to an aluminum alloy manufacturing technology, in particular to a method for preparing an aluminum alloy cylinder block and cylinder head extrusion casting for a high-speed rotary cylinder of a numerical control machine tool. Background technique [0002] With the development of high-end CNC machine tools, the performance requirements of important parts such as high-speed rotating cylinders and cylinder heads in machine tools are getting higher and higher. At present, high-speed rotary cylinders of CNC machine tools are usually made of cast steel. The parts are heavy, and the centrifugal force is large during high-speed rotation. Long-term use will cause deformation, which will affect the machining accuracy of CNC machine tools. Or when it is replaced, more auxiliary equipment and manpower are required, and the cost is higher. Therefore, the machine tool manufacturer considers that the machine tool itself can meet the machining accurac...
