在实际生产条件下,特别是在加工高强度材料时,常常因为切削过程温度过高而影响生产率的提高和加工成本的降低。降低切削过程温度的途径之一是改进现有的刀具冷却方式。苏联多尼雅金斯克工学院研制了一种自备冷却系统的车刀。该车刀可提高加工钢时的耐用度。如图所示,刀具本身为一焊接或机械夹固刀片的车刀,车刀刀杆内制有一密封真空槽,槽内局部注有作为载热体的冷却液。槽起导热管的作用。槽壁上铺一层细格网以起分流作用。刀片的冷却方式是:当冷却液受热蒸发时,载热蒸气便流向槽的另一端,并在此端冷凝成液体而自动
In actual production conditions, especially in the processing of high strength materials, often due to the cutting process temperature is too high and affect the productivity and reduce processing costs. One way to reduce the temperature of the cutting process is to improve the existing tool cooling. Domingo Jinsk Institute of Technology developed a self-cooling system turning tool. This turning tool increases durability when machining steel. As shown in the figure, the tool itself is a lathe with welded or mechanically entrained blades. A sealed vacuum slot is made in the lathing arbor, and the coolant inside the slot is partially filled with coolant as a heating medium. Trough heat pipe role. Slot wall with a layer of mesh to play the role of diversion. Blade cooling is: When the coolant is heated evaporation, the heat-carrying vapor will flow to the other end of the tank, and at this end condenses into liquid and automatically
