本文介绍的带有自动送料机构的径向预压紧热切下料装置由切料机构、杠杆式径向预压紧机构、双滑块式送料机构和平行四边形托料机构等四部分组成。使用这种装置下料时,棒料压紧可靠,料段质量有很大提高,下料重量误差由原来的2.9～3.4%减少到1.3～1.6%。 In this paper, the radial pre-pressing and cutting device with automatic feeding mechanism is composed of four parts: cutting mechanism, lever-type radial pre-compacting mechanism, double-slider feeding mechanism and parallelogram supporting mechanism. When the device is used for cutting, the bar material is pressed tightly, the quality of the material section is greatly improved, and the error of cutting weight is reduced from 2.9 to 3.4% to 1.3 to 1.6%.
