Abstract : on the basis of technology analysis for the nut - box , this paper instroduced the structure of bending forming die of shape stamping that was formed directly 文摘:通过对螺母盒的工艺分析，介绍了形弯曲件一次弯曲成形的模具结构。
The fracture reasons of forming dies , which cracked during forming process of cranks , were analyzed by means of chemical composition analysis , metallographic examination and fracture analysis in this paper 摘要采用化学成分分析、金相检验和断口分析等方法，对开裂的成型模进行了分析。
It can not only manufacture die holders of various standards for customers , but also non - standard holders according to their drawings . the processing includes precise frames , water - carrying holes , angle holes , thimbles , front edges , and 3 - d forming dies 不仅?客户制作各种标准模架，还可根据客户的来图要求，制作各种非标模架，加工范围包括精框精框，运水孔加工斜孔顶针止口及三维成型模具加工等。
The " hydraulic horizontal typed special machine for angle switching of angle steels " does not need any other forming dies when operating angle switching ; it only needs the qualification adjustment of the first article ( self - made angulartemplet is needed to measure ) according to operating instructions ; then . consecutive work can be achieved 该“液压卧式角钢开合角专用机” ,不使用其他任何成型模具，在开合角作业中，只需根据该机使用说明书的要求进行首件调试合格(需用自制角度样板测量)即可进行连续作业。
It is automated product line , which process is as follows : first , loading comminution pvc materials to mixing device manully , then running the auto work cycle process - drying and transmitting to loading device - plasticizing , extruding and forming cooling the forming dies - cooling in the cycle water container - drying with compress - air blowing - towing with tow device - automatic punch device - transmitting workpiece with manipulator - placing workpiece - last , moving the workpiece manually 在生产门封条的同时完成了打孔45精确切角机械手取料和全自动摆料工序，整条线只需一人操作，每段切除的料角是老式生产线的1 5 ，大幅度提高了成品率。
