1, Overview
The Aluminum Tube Cold Drawing Process: A Key for Enhancing the Quality and Dimensional Precision of Aluminum Alloy Tubes.
The aluminum tube cold drawing process is an artfully crafted method for fabricating aluminum rods based on specific technological stipulations. Through successive cold drawing processes, the cross-sectional shape of the aluminum rod is meticulously compressed, significantly enhancing the surface quality and dimensional precision of the rod. This acclaimed process is ideal for producing high demand aluminum alloy tubes and is widely utilized in sectors such as aviation, automotive, rail transit, electronics, etc.
2, Process
The Fundamental Process of Cold Drawing in Aluminum Tube Manufacturing.
The fundamental procedure of cold drawing technology for aluminum tubes encompasses a series of steps including the selection of rodstock, pre-treatment, initial drawing, drying, intermediate drawing, heat treatment, ultimate drawing, straightening, pickling and cold treatment. The process of the initial drawing includes setting the aluminum rod on the machine tool for primary drawing work to induce deformation in the rodstock. The function of the intermediate drawing is to draw a steel bar in the middle to achieve the optimum shape dimension for the manufacture of the aluminum tube. The purpose of the final deep drawing is to eliminate burrs on the aluminum tube, further improve the surface quality and dimensional precision of the aluminum tube.
