汽车轮胎螺栓温挤压工艺及模具设计

随着汽车工业的发展,汽车轮胎螺栓的需求量变得非常的大,对其成形过程进行研究并探寻最合理的成形方案有着重要的意义,其形状属于带法兰的阶梯轴,针对其结构特点,结合带法兰阶梯轴挤压成形工艺,相对于多工步的冷挤压方法,本文提出了汽车轮胎螺栓的一次温挤压精锻成形工艺方案以及毛刺与上模运动同向的模具设计方案,设计了螺栓温挤压模具,克服了成形过程中产生的折叠问题,运用有限元模拟软件DEFORM对其成形过程进行数值模拟并分析了模拟产生的原因。

Warm Extruding Process and Die Design of Automobile Tire Bolt

With the development of the Auto industry, the demand of the part of tire bolts is ascending to a high level, it is meaningful to research the process and look for a suitable method of deformation.h shape is belong to flanged shaft. This paper in combination with characteristics of structure and extruding process of flanged shaft, relative to the multiplex steps cold extrusion method,puts forward warm extrusion precision forming process, design die of tire bolt and overcome the weakpoint of fold, using the simulation software of finite element to simulate the process and analyze the reason of the generation of fold.
