摘要：

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。

The door frame of wind power tower is an important component of wind power tower. However, it is difficult to produce by traditional technology of complex technology due to its high dimension precision. A new forging technique was developed based on the current manufacturing equipment, the size and shape of workpiece, and the material characteristics. The primary parameters of forging process were calculated by combining with those relevant formulas during the pre-calculation process, and it was convenient to determine the raw material dimension and manufacturing equipment. Thus, the raw material usage value was reduced by rolling. In verification process, the forming step by mold was numerically analyzed by ANSYS Workbench in the forming by die with pre-compress technique. Furthermore, the plastic deformation was pre-observed, and the pre-pressed shaping dimension and mold size were determined. Thus, a new way of manufacturing is provided for producing in-oval shape with equal cross section.
