中波瓦压出波形后,用人工切除横边,不但速度慢、效率低,而且劳动强度大,切割质量不好。吉林松江水泥厂石棉水泥制品車間,制成了中波瓦波前切边机,利用圓盘刀片的高速回轉和往复移动来切除横边。圓形切割刀片容易制造,使用寿命长,不直接与瓦模接触,不会損伤瓦模。中波瓦切边机的結构見附图。接坯小車由車架、 After the wave is pressed out by the Bova, the horizontal edge is manually removed, which is not only slow and inefficient, but also has great labor intensity and poor cutting quality. The Jilin Songjiang Cement Plant asbestos cement product workshop has made the Zhongbo wave front trimming machine, using the high-speed rotation and reciprocating movement of the disc blade to cut the transverse edge. The circular cutting blade is easy to manufacture, has a long service life, does not directly contact with the die, and does not damage the die. The structure of the Zhongbo Wabian machine is shown in the attached drawing. The billet trolley consists of a frame,
