我厂有一锻件,锻后需热态切边、冲孔和校形,这三个工序要用三套模具分别在自由锻锤上进行。后来,我们对此工艺作了革新,将切、冲、校三套模具合拼为一体(复合模结构如图示),在锻锤上实现了一模一次精整成形。从而,大大改善了劳动条件,减轻了劳动强度,提高了生产效率三倍,并节约了能源。该模的主要特点是:易损件采用了紧固连接或嵌镶结构,冲片7与冲刃8均可两面使用并可拆换,从而提高了模具寿命;切、冲、校三序是依次连续进行的,这样不仅工艺合理,
I have a factory forgings, hot forging after trimming, punching and school-shaped, these three processes to use three sets of molds were carried out on the free forging hammer. Later, we made innovations in this technology, the cutting, punching, school three molds together into one (composite mold structure as shown), the forging hammer to achieve a once-through finishing. As a result, working conditions have been greatly improved, labor intensity has been reduced, production efficiency has been tripled, and energy saved. The main features of this mold are as follows: the consumables adopt the fastening connection or the mosaic structure, the punching sheet 7 and the punching blade 8 can both be used on two sides and can be replaced, thereby improving the mold life; cutting, punching and schooling are Followed by continuous, so that not only a reasonable process,
