造型工作经常有用车板来作的,在30“直径以上的铸件,固然是用大型(大英)车心好,而小型铸件在隔几天开一炉的车间里,也用大型车心就不经济了。因为第一要轴座多,第二校正轴座相当费时。因此只用一根木条,头上钉上一个搭子,利用型箱,括板,木片等做架子校平高度,这样的做法在括动车板典型砂磨擦时很容易使车板架走动,而使铸件变形,同时时间也不很短,至少要10—20分钟左右,尤其在车箱圈的时候,要拿开括板,放进箱圈再把车板校正才能造型。
The modeling work is often done with car plates. Castings above 30 ”in diameter are of course large, but small castings are used in large workshops every few days. Uneconomical.Because the first axle seat, the second correction axle seat is quite time-consuming.Therefore, only a piece of wood, head nailed a take child, the use of boxes, brackets, wood and other shelf leveling leveling, This approach includes the typical car sand plate rub rub easily move the car rack, leaving the deformation of the casting, at the same time not very short, at least 10-20 minutes, especially in the car when the ring, to take away Plate, into the box and then the car plate correction to modeling.
