在铸造生产中,紧实型砂是造型和制芯的重要工序,它不仅影响铸件的质量,而且影响生产效率。同时,对手工造型来讲,紧实型砂又是一道劳动强度最大的工序。为了减视劳动强度,提高生产效率,我们研制了一种轻型捣固机,经多年使用,效果很好。一、整体结构和动作原理轻型捣固机的结构见图1所示,它主要由机体、壳体、风咀、阀杆和气门环等组织。轻型捣固机动作原理如图2所示。当按下手动按柄,塞销压迫钢球打开进气门之后,压
In the casting production, compact sand is an important process of molding and core making, which not only affects the quality of castings, but also affect the production efficiency. At the same time, in terms of hand-molding, compact sand is a labor-intensive process. In order to reduce labor intensity and improve production efficiency, we have developed a light tamping machine that works well for many years. First, the overall structure and principle of operation Light tamping machine structure shown in Figure 1, which is mainly composed of the body, shell, Fengzui, stem and valve ring and other organizations. Light tamping machine action principle shown in Figure 2. When you press the manual handle, the pin presses the ball to open the intake valve, the pressure
