全面分析和比较了 G4- 73型离心风机在较大负荷变化范围内分别采用轴向导流器调节和轴向导流器加双速电动机调节的运行经济性 ,对各种风机的节能具有重要的指导意

In order to resolve the problems of plastic formation and accuracy control of blank,the warm cold compound forming process(preliminary shaping-backward extrusion forming-cold extrusion sizing) and the forming theory of "guiding flow in axial direction ","push extrusion forming " were adopted based on the study on the theory and experiment and the corresponding dies were developed.

为了解决毛坯塑性成形和精度控制的问题,通过理论和试验研究,提出温冷复合成形的工艺(预成形-反挤成形-冷挤整形)和"轴向导流"、"推挤成形"的成形原理,并研制了相应的模具;解决了毛坯塑性成形、精度控制的难点和试验中出现的氧化、内孔局部收缩等问题。

The precision plastic forming theory of warm cold compound forming that formation of geometric shape is guaranteed by warm forming and accuracy by cold forming,and the forming methods of‘guiding flow in axial direction’,‘push extrusion forming’,‘control the deformation gradually’, ar.

针对机体座零件几何形状的特点,通过工艺分析,制定了合理的挤压件图和预成形→反挤成形→冷挤整形的工艺路线;采用了以温成形保证几何形状成形、冷成形控制精度的温冷复合成形的精密塑性成形原理和“轴向导流”、“推挤成形”、“逐次控制变形”的成形方法,为机体座精密塑性成形奠定了基础。
