【摘要】：针对汽车减振器外壳结构特点,通过工艺分析提出通过正向挤压和侧向挤压复合工艺实现热挤压一次成形的新工艺的解决方案和设计路线,设计了减振器外壳热挤压模具。凸模头部采用平底锥形设计,可以降低单位挤压力;凹模采用挤压筒和挤压凹模的组合结构,可以解决凹模加工工艺性问题及便于零件的退卸料;并论述了模具的结构原理和工作原理。为确保模具符合热挤压实验的要求,对模具的关键部件进行了理论分析和计算,并通过实验方法成形出了表面光滑无缺陷、尺寸精度和力学性能均符合要求的筒形件,实验结果表明了该工艺方案和模具结构设计的可行性和实用性。
[Abstract]:According to the structural characteristics of automobile shock absorber shell, the solution and design route of a new hot extrusion primary forming process through forward extrusion and lateral extrusion composite process are put forward, and the hot extrusion die of shock absorber shell is designed. The head of the convex die is designed with a flat bottom cone, which can reduce the unit extrusion pressure, and the die adopts the combination structure of the extruding cylinder and the extrusion die, which can solve the problem of machining technology of the die and facilitate the discharge of the parts. The structure and working principle of die are discussed. In order to ensure that the die meets the requirements of hot extrusion experiment, the key parts of the die are theoretically analyzed and calculated, and the cylindrical parts with smooth surface and no defects, size accuracy and mechanical properties are formed by the experimental method. The experimental results show the feasibility and practicability of the process scheme and die structure design.
