【正文】 影響零件的質(zhì)量,因此在加工前要做好頭架及頂尖的檢測工作。加工薄壁軸類零件,最好采用夾持工藝臺,夾緊力不可過大,否則容易在工件圓周上產(chǎn)生“內(nèi)三角”變形。對工件的一些棱邊、銳角、孔口進行倒鈍,R化。在磨削加工、電加工過程中,工件會有一定磁化,具有微弱磁力,十分容易吸著一些小東西,因此在組裝之前,要對工件作退磁處理,并用乙酸乙脂清洗表面。對發(fā)現(xiàn)的問題,可采用逆向思維法,即從后工序向前工序,從精加工到粗加工,逐一檢查,直到找出癥結(jié)。Analysis of the finishing mold control 1, Introduction Mold is a large group with the parts from, the quality of parts with a direct impact on the quality of mold, and the final parts to plete the finishing quality assurance in turn, so that control is crucial to finishing. Most of the mold in the domestic manufacturing enterprises, finishing stage of the method used is generally grinding, EDM and fitter to deal with. At this stage to control the good parts deformation, internal stress, shape and size of precision tolerances and many other technical parameters, in the specific production practice, the operation more difficult, but there are still many effective methods of experience is worth learning from. 2, die finishing process control Mold parts processing, a general guiding principle is for different materials, different shapes, different technical requirements for adaptive processing, it has a certain degree of plasticity through the control of processing to achieve good machining results. According to the appearance of the shape of different parts, the parts can be broadly classified into three types: shaft, sheet metal and shaped parts, the mon process along the lines of: roughing heat treatment (quenching, quenching and tempering) Grinding Xinhua processing fitter (Surface Treatment) group with processing. parts of heat treatment Parts of the heat treatment process, in the hardness of parts was required, the need to control the internal stress to ensure that the size o
