Abstract
一种弧形砂箱,沿箱框内壁设有弧形钢板。用这种砂箱生产铸件时,弧形钢板受热膨胀,产生挤压铸件的力,使铸件在挤压力作用下凝固,从而解决了一般砂箱在生产铸件时,铸型退让,箱框受热膨胀,铸件随之胀大,缩孔、缩松严重的问题。
这种砂箱适用于厚大石墨铸铁件和沉缩严重的高大铸钢件。
Description
本发明属于铸造工艺装备。
采用一般砂箱生产铸件时,型砂退让和箱框受热膨胀,铸件随之胀大,从而增大了铸件的缩孔率,尤其是厚大铸件更为突出。针对上述缺点,提供了一种弧形砂箱。
附图一是弧形砂箱结构示意图(主视图),其中一为箱框,2为弧形钢板。
附图二是弧形砂箱结构示意图(俯视图),其中1为箱框,2为弧形钢板。
本发明的要点在于,沿箱框内壁设置弧形钢板。采用这种砂箱生产铸件时,弧形钢板受热膨胀,产生挤压铸件的力,使铸件因受到挤压力不至胀大,从而提高了铸件的内在质量。
砂箱的弧形钢板的厚度可为2mm~6mm,其形状可是园心角为90°的弧线。砂箱的箱框可用钢筋围制而成。
用这种砂箱生产石墨铸铁件时,能充分利用石墨化膨胀进行自身补缩。用于生产厚大石墨铸铁件效果更佳。
这种砂箱在用于生产高大铸钢件时,可抑制其沉缩。
Claims (5)
