石家庄煤机厂铸钢车间试制成功一种凸轮型快速箱卡,克服了从前用螺栓夹紧砂箱的很多缺点,特点是:避免了合箱后的敲击和振动,防止夹箱造成的掉砂和坏型;锁紧力强,牢固可靠。由于不是单靠凸轮锁紧,而是依靠顶轴与凸轮中心的偏心作用共同锁紧,所以锁紧后不怕振动,并且越张越紧;使用方便;可调量大,适用于各种砂箱,全调量可达140mm;维修方便。只要保证焊接牢固,顶轴灵活就能使用;制作简单,除顶轴导向套加工外,凸轮只用汽割按样板切开即可;可靠耐用不易损坏,适合铸造特
Shijiazhuang Coal Plant Steel Plant trial success of a cam-type rapid box card, to overcome the past with a bolt clamping flask many shortcomings, characterized by: to avoid knocking and vibration after the combined box to prevent the carton caused by the swap Sand and bad type; strong locking, solid and reliable. Because not rely solely on the cam lock, but rely on the top center of the eccentric cam and the center of the common locking, so after the lock is not afraid of vibration, and more tension more tense; easy to use; adjustable large, suitable for all kinds of sand box , Full volume up to 140mm; easy maintenance. As long as the guarantee of welding firm, the top shaft can be used flexibly; simple production, in addition to the top-axis guide sleeve processing, the cam cutting only by steam cutting according to the model; reliable durable durable, suitable for casting special
