简介：拉延筋和拉延槛在拉延件中应用广泛，在拉延件辅助面上设置拉延筋或拉延槛，不仅能够增加进料阻力，使拉延件表面产生一定张力，提高拉延件的刚度，从而使零件减少由于弹复而产生的凹陷、扭曲、波纹等缺陷。而且能够调节材料的流入情况，使板料均匀地进入模腔，防止零件在拉延过程中出现“多则皱，少则裂”的现象。

简介：在生产中一些盛水盛油和充气的容器设备或管道在使用过程中，有时发生泄漏现象，由于种种原因不可能泄压放水（汽、油）或者放不干净，而要求带水带压进行焊接修复，以保证企业安全生产。本文根据多年实践经验，参考国内同行的相关资料，阐述带水（汽）、带压焊接修复技术和常用的操作方法。

简介：集成CAD/CAM/CAE/PLM为一体的三维参数化UG软件是许多现代企业的必然首选,而要满足不同企业的不同要求,就需要利用UG自身提供的二次开发接口及其语言Grip。本文通过两个实例,对其具体要求的分析、构思、后续的语句编辑、链接等,利用Grip语言二次开发了符合要求的程序。

简介：针对汽车前罩装饰件变形问题，依靠MoldFLow软件的分析，找出了变形过大产生的原因，提出了修改措施，解决了问题。

简介：电磁辅助钣金拉延快速成型技术是一种新型的钣金件拉伸成形技术，修形磁场的设计是电磁辅助钣金拉延快速成型系统磁场设计的关键部分。用ANSYS模拟了单元体之间磁场的分布情况，并用实验验证了修形磁场的可行性。

简介：石油天然气行业标准SY／T4078—95《钢质管道内涂层液体涂料补口机补口工艺》在适用范围、焊口表面处理、现场施工过程及焊口补口涂层检验等部分都有不妥之处。成功的工程实例表明：无溶剂环氧树脂作为管线内壁涂层的补口涂料是非常合适的。它可以使传统的补口工艺更加科学、合理。为保证钢管内壁涂层的整体质量，应尽快予以修订该行业标准。
