风电塔架门框是风电塔架的重要组成部分,其尺寸要求严格,传统锻造工艺复杂,生产困难。现根据实际生产设备、零件尺寸、形状及材料特点,开发一种新型风电塔架门框的锻造工艺。该工艺在“前期计算”过程中,结合相关公式,计算出风电塔架门框锻造过程中所需的各种主要参数,方便确定原材料使用规格及生产过程中的使用设备;利用辗环技术降低了原材料的使用量;在分析验证过程中,使用ANSYS Workbench对该工艺预压后模具成形过程中的模具成形工步进行有限元分析,预先观测到模具冲入时,风电塔架门框的塑性变形情况,准确确定预压成形尺寸及模具尺寸,为内椭圆等截面型风电塔架门框的生产提供了一种新思路与新方法。
Wind power tower frame is an important part of wind power tower, its size is strict, the traditional forging process is complex, production difficulties. According to the actual production equipment, parts size, shape and material characteristics, the development of a new wind tower frame forging process. The process in the “pre-calculation” process, combined with the relevant formula to calculate the wind power tower frame forging process required for the various key parameters to facilitate the determination of raw material specifications and use of the production process equipment; use of rolling ring technology Reduce the amount of raw materials used; in the process of analysis and verification, using ANSYS Workbench finite element analysis of the mold forming steps in the process of forming the mold after the preloading process of the process, precast the mold plasticity Deformation, accurately determine the size of the pre-forming and die size, such as the inner cross-section of the oval cross-section of wind power tower frame provides a new way of thinking and new methods.
