毕业设计（论文）-支撑板冲压模具设计毕业设计说明书.doc

摘要:
本论文根据产品图样,分析冲裁件的形状、特点、尺寸大小精度要求、表面质量及所用材料等冲压工世性,在此基础了,根据复合模的高效、高质量等特点选用倒装的复合模,上出件,下出废料,废料直接从冲床台面孔排出,不阻塞,操作方便、安全。上模采用橡胶,起到一定的平整作用,提高工件质量,甚至减少工序。分别设计了凸凹模、凸模、凹模的结构,凸模采用成型加工或线切割,冲裁部分进行热处理,由螺钉固定,刚性推件,弹性卸料装置橡胶的弹性把料板由下而上推出,随上模的动作而动作,运动平稳可靠且不易损坏模具,采用中间导柱圆形有利用安装,且因安装不当而造成模具损坏,根据冲压力选择开式固定台压力机
关键词:冲裁件、级进模、设计
Abstract:The present paper basis product pattern, the analysis blanking shape, the characteristic, the size size precision request,the surface quality and use ramming labor world and so on the material, in this foundation, according to the superposable die the superposable die which was highly effective, high grade and so on the characteristic selects inverts, on, got down the waste material, the waste material discharges directly from the punch press Taiwan face,did not block, ease of operation, security. The top die uses the rubber, plays to the certain smooth role, improves the work piece quality, even reduces the working procedure. Has designed the convex-concave mold, the raised mold, the concave mold structure separately, the raised mold uses takes shape the processing or the line cuts, the blanking partially carries on the heat treatment, by the screw retention, the rigidity pushes, the elastic dumping device rubber elasticity from bootom to top promotes the yard lumber, but acts along with the top die movement, the movement steady reliable also is not easy to damage the mold among, uses the guide pillar circular to have the use installment, also because of does not install when but creates the mold damage, according to flushes the pressure to choose the type fixed platform press.
Key word: Blanking、superposable die、design.
前言
随着经济的发展,冲压技术应用应用范围越来越广泛,在国民经济各部门中,几乎都有冲压加工生产,它不仅与整个机械行业密切相关,而且与人们的生活紧密相连。
冲压工艺与冲压设备正在不断地发展,特别是精密冲压。高速冲压、多工位自动冲压以及液压成形、超塑性冲压等各种冲压工艺的迅速发展,把冲压的技术水平提高到了一个新高度。新型模具材料的采用和钢结合金、硬质合金模具的推广,模具各种表面处理技术的发展,冲压设备和模具结构的改善及精度的提高,显著地延长了模具的寿命和扩大了冲压加工的工艺范围。
由于冲压工艺具有生产效率高、质量稳定、成本低以及可加工复杂形状工件等一系列优点,在机械、汽车、轻工、国防、电机电器、家用电器,以及日常生活用品等行业应用非常广泛,占有十分重要的地位。随着工业产
