挤压筒参数的选择及其对应力的影响

The Parameters of Squeeze Tube Chosen and Its Affecting the Stress of It

挤压筒是挤压机设备中的一个重要组成部分 ,采用多层套组合式挤压筒 ,可改善挤压筒的受力条件 ,增加承受能力 ,提高使用寿命 .在使用损坏变形后 ,只需更换内衬 ,减少了材料损耗 ,降低了成本 .为延长挤压筒的寿命 ,除选择合适的材料外 ,选择正确的技术参数尤为重要 .在挤压机各零部件的强度计算中 ,可通过对挤压筒几个主要设计参数的修订 ,来完成其复杂的计算 .

The multi case,combination squeeze tube chosen in extruder,can improve the stress state ,increase its capacity of bearing, extend the service life of it. Only replacing the damage and deformation ciner in use, can reduce spillage of material thus lower its cost. In order to extend the service life of it, besides choosing the rational material, the suitable parameters selected is specially important. The complicated strength computation of its spare parts can be completed by amending the main parameters of squeeze tube.
