摘要
采用温挤压成形技术对铝合金汽车空调高压汽缸体进行精密温挤压成形加工,其挤压件表面粗造度Ra可以达到0.8～1.6。尺寸精度高,尺寸一致性好,完全满足汽缸体的技术要求。同时温挤压成形的汽缸体由于无砂眼、气孔、裂纹和折叠等缺陷,大大提高了缸体的使用寿命。
The warm extrusion technology was used to the precision processing of aluminum alloy high-pressure cylinder for automotive air conditioning, the extrusion surface roughness Ra can reach 0.8 to 1.6. High dimensional accuracy and good consistency of size fully meet the technical requirements of the cylinder body. Warm extrusion cylinder body , with no sand holes, no pores, cracks and folding defects, greatly improves the life of the cylinder.
