Embodiment 1

[0065] The processing technology of the 2A14 aluminum alloy high cylinder part in this embodiment includes the following processing steps:

[0066] The first step is to prepare raw materials: the raw materials are aluminum alloy round bars cast by semi-continuous casting;

[0067] The second step, blanking: the semi-continuous casting aluminum alloy round bar is sawed and cut into the bar required by the process;

[0068] The third step, heating: put the above-mentioned bar into the furnace at room temperature, and heat it to 460°C;

[0069] The fourth step, forging: forging is carried out on a 3600T hydraulic press at a temperature above 420°C. The forging process is as follows, first axial upsetting, then two radial elongation, upsetting, and then axial elongation, and then Chamfering, rounding, upsetting, flat end face, and finally punching;

[0070] The fifth step, machining: air-cool the blank after forging and punching to room temperature, and machining to remove possi...

Abstract

The invention relates to a processing technique of a high aluminum alloy cylinder. The processing technique includes the following technical processes: preparing raw materials->baiting->heating ->forging->machining->heating->expanding holes of a mandrel supporter->drawing out a mandrel ->heating->flattening an end face->heating->expanding holes of the mandrel supporter->heating ->flattening an end face->heating->rolling ring->thermal treatment ->machining. Through hot die forging and optimized heat treatment method, the defective percentage of the high cylinder after shaping is obviously reduced, the anisotropism of the high aluminum alloy cylinder is obviously decreased, and cost of processing and reshaping in post period is saved, and the material utilization rate is greatly improved; particularly, the aluminum alloy ductility is effectively expanded; the high cylinder is mainly used for aviation and other fields; the work piece after processing by the technique can perfectly realize the lightweight goal of an aerospace craft.

Description

technical field [0001] The invention relates to the technical field of aluminum alloy processing, in particular to a processing technology suitable for 2A14 aluminum alloy high cylinder parts. Background technique [0002] Aluminum alloy is the material of choice for lightweight aircraft and spacecraft. Rotary parts made of aluminum alloy have a high height and thin wall thickness, and require high mechanical properties in three directions. Forming difficulty. In current actual production, although the shape of the 2A14 aluminum alloy high cylinder is simple, it has the particularity of the structure such as thin wall and deep cavity. The traditional forming method has low production efficiency, low material utilization rate, requires a large tonnage, and the deformation is uneven, and the deformation is not easy to control; the existing forging and ring rolling process, due to the forming characteristics of the forging and ring rolling process, The anisotropy of the m...
