收放机架安装支架是汽车上的一个结构零件，它是板料成形零件，采用的材料是SPHC。通过分析收放机架安装支架的工艺性，确定了在技术上可行，经济上合理的冲压工艺方案，并且设计出生产此零件的全序模具。通过对零件结构工艺性分析，设计中采用了四副模具来完成收放机架安装支架的成形。第一副为落料—冲孔复合模，落料的同时冲出两个小圆孔。落料—冲孔复合模的特点是工作效率高。第二副模具为弯曲模，由于有一个较大的弯曲半径，所以在设计中主要考虑回弹因素对成形精度的影响。第三副为斜楔冲孔模，模具设计中采用了斜楔机构，冲出弯曲面上的长圆孔。最后一副模具也是弯曲模，用来弯曲两边。本次设计不但对模具总体结构进行了设计、还运用CAD软件绘制模具装配图和零件图。设计中采用功能强大的模具CAD/CAM软件UGNX作出零件的三维数值模型，不仅使零件看起来更加直观，而且为模具的CAM提供了依据。同时对制件的冲压工艺进行了设计并选择了合适的压力机型号。 关键词: 冲压工艺 模具结构 回弹 斜楔机构

Answer 1

Folding rack mounting bracket is the car on a structural parts, it is sheet metal parts, the materials used is SPHC. Through the analysis of releasing rack mounting bracket process, identified in the technology feasible, economically reasonable stamping process scheme, and is designed to produce parts of this sequence mold. Through parts of the structure process of analysis, design using the four moulds are used to complete retraction rack mounting bracket forming. The first side for blanking and punching compound die of blanking and at the same time, out of two small holes. Blanking punching compound die is characterized by high working efficiency. Second side mold for bending die, due to having a large radius of curvature, so in the design of the main considered factors of spring back effect on the forming accuracy. The third side is inclined wedge and punching die, die design using the wedge body, out of the long round hole of curved surface. Finally, a die and bending die for the curved sides. This design not only to die overall structure of the design, use CAD software rendering mold assembly drawing and parts drawing. Used in the design of powerful mold CAD / CAM software UGNX to make parts of the three-dimensional numerical model, not only make it more intuitive parts, and molds for the CAM provide a basis. At the same time on parts stamping process design and selection of suitable press model.
