我厂生产的石油钻采配件的锻件,百分之八十以上是胎模锻造的,年产量达几万件。在一九七二年以前,胎模是由两人抬,劳动强度大,不安全。在车间党支部领导下,发动群众大搞技术革新,于一九七四年试制成功了如图1所示的电动四连杆式翻模机。该机一直用于生产,使用效果较好。一、翻模机的性能翻模机由一个人坐着操作,可以完成下列动作: 1.将胎模移入和移出下砧面(机动); 2.将模体在下砧上空垂直升降,并能在升降行程(约150毫米)范围内的任意高度上停
The oil forgings produced by our factory are more than 80% of the forgings of tire molds, with an annual output of tens of thousands of pieces. Before 1972, the tire mold was carried by two people and was labor-intensive and unsafe. Under the leadership of the party branch of the workshop, mobilizing the masses to devote major efforts to technological innovations was successfully piloted in 1974 as the electric four-bar turning machine shown in Figure 1. The machine has been used for production, the use of better. First, the performance of turning machine Turning machine by a person sitting to operate, you can complete the following actions: 1. The mold into and out of the lower anvil (motor); 2. The mold in the vertical anvil above the anvil and can Stop at any height in the ascending and descending stroke (approx. 150 mm)
