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。裝配一般先裝導柱導套,然后裝模架和凸凹模,然后再對各處間隙,特別是凸凹模間隙進行組配調整,裝配完成后要實施模具檢測,寫出整體情況報告。對發現的問題,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,解決問題。 In grinding processing, machining process, the workpiece can be magnetized, has weak magnetic, very easy to suck a little things, so before assembly, to the workpiece demagnetization, and acetic acid ethyl ester to clean the surface. General assembly to install guide pin, guide sleeve, then pretend to die set and convex concave die, and then with the clearance, especially the intensive clearance adjustment, equipping assembly should implement the mold after the completion of testing, write a report as a whole. For the problems found, can adopt the reverse thinking method, that is, from the work procedure, forward from finishing to rough machining, check them one by one, until find out the crux, solve the problem. 　　路沿石模具表面在加工時留下刀痕、磨痕是應力集中的地方,是裂紋擴展的源頭,這些會直接導致在生產混泥土路沿石模具使會不容易脫模,外觀難看,達不到要求。因此在加工結束后,需蠕動泵 保定建筑設計 保定網站建設 保定網站制作 保定網絡公司 保定辦公家具 保定輕鋼別墅 要對零件進行表面強化,通過鉗工打磨,處理掉加工隱患。對工件的一些棱邊、銳角、孔口進行倒鈍,R化。方法為表面拋光,打磨去掉硬化層。 Luyandan surface in the processing of die leaving the grinding tool and is the place of stress concentration, is the source of crack propagation, these will directly cause in the production of concrete luyandan mould will be not easy demoulding, ugly appearance, can not meet the requirements. So at the end of the process, need to surface strengthening of parts, through the bench grinding, get rid of processing. Some of the artifacts edge, acute Angle, orifice blunt, R. Methods for surface polishing, polishing to remove hardened layer.
