一般地坑造型生产周期都很长,开箱时間是凭經驗估計,不能准确的控制燒件冷却时間。为了合理的縮短生产周期,充分利用作业面积,我們采用了用热电偶来测量地坑鑄件冷却时間的办法,經試用結果收到了一定的效果。以1A64車床床身鑄件为例,零件毛重6400公斤,净重4920公斤,輪廓尺寸5600×1025×680公厘,材料是Ⅰ级鑄鉄,原估計冷却时間为60小时,經測量后縮短了20小时。
Generally pit modeling production cycle is very long, out of box time is estimated by experience, can not accurately control the cooling time of the burning pieces. In order to reasonably shorten the production cycle and make full use of the work area, we used the method of measuring the cooling time of the pit casting with a thermocouple, and the result of the trial has received a certain effect. To 1A64 lathe bed castings, for example, the parts gross weight of 6400 kilograms, net weight 4920 kilograms, contour size 5600 × 1025 × 680 mm, the material is Ⅰ grade castings, the original estimated cooling time of 60 hours, after measuring the shortened by 20 hour.
