在现有的造型机中,大多数仍采用有箱造型。砂箱的加工由于其数量大、精度高、工序多,是上工装的重要任务之一,对于中小厂更感困难。去年,我们在上生产线时,改掉了传统的机械加工镶嵌销套的方法,而用了一种低熔点合金将销套固定在箱耳中,结果大大缩短了工装准备时间,也节省了不少开支,有力地促进了机械化生产的实现。现将有关情况介绍如下: 一、工艺简介 In the existing molding machine, most still use a box shape. Due to the large number of sand box processing, high precision, multi-process, is one of the important tasks on the tooling, more difficult for small and medium-sized factory. Last year, when we went to the production line, we eliminated the traditional method of machining insert bushings and used a low-melting-point alloy to hold the bushings in the box ears. As a result, tooling preparation time was greatly reduced, Less expenditure, effectively promoted the realization of mechanized production. The relevant information is as follows: First, the process profile
