建厂局二处机械队为了配合采用高强度钢絲的预应力空心板生产,在向兄弟单位学习的基础上,通过工人、干部和技术人员的三结合,设计制造了高强钢絲压痕机,见图1。一、技术数据电动机型号 2.8瓩 1420转/分电压 380伏速比 1:11.5 压痕滾轮速度 124转/分压痕钢絲直径 3-5mm 工作效率 300公斤/小时(以5钢絲计) 二、传动简图(图2) 三、压痕钢絲试验用4高强钢絲作压痕试验,刻痕前,极限强度17600kg/cm~2,压痕后(单面压痕深度0.16mm),极限强度16500kg/cm~2,强度损失6.5％。四、存在问题压痕轮材料采用T_(10)时,硬度和耐磨性较
Construction Bureau Bureau two mechanical team in line with the use of high-strength steel prestressed hollow slab production, to learn from the brothers unit, through the combination of workers, cadres and technical staff to design and manufacture of high-strength steel indentation machine ,see picture 1. Technical Data Motor Model 2.8 瓩 1420 RPM Voltage 380 V Ratio 1: 11.5 Indentation Roller Speed 124 rpm Indentation Wire Diameter 3-5mm Working Efficiency 300 kg / h (Based on 5 Wire Gauge) Second, the transmission diagram (Figure 2) Third, the indentation wire test 4 high-strength steel wire for indentation test before the indentation, the ultimate strength of 17600kg / cm ~ 2, indentation (indentation depth of 0.16mm) , The ultimate strength of 16500kg / cm ~ 2, the loss of strength of 6.5%. Fourth, there are problems The indentation wheel material T_ (10), the hardness and wear resistance than
