LJ连续挤压机在挤压过程中 ,主轴受热伸长 ,造成主轴向一端移动 ,产生很大的轴向力 ,对主轴产生有害影响 ,严重磨损堵头和挤压轮 ,影响产品的成材率和产品质量 .为了有效地减少挤压过程中有害的主轴位移和改善主轴受力状态 ,设计了一种联轴器在主轴受较小载荷时允许主轴作轴向游动 .实践表明 :改进后的挤压机主轴系统受力得到很大改善 ,堵头和挤压轮使用寿命有很大提高 ,设备性能有明显改善 ,生产的产品成材率和合格率都有显著提高 .
LJ continuous extrusion machine in the extrusion process, the main shaft heated elongation, resulting in one end of the main shaft to move, have a great axial force, the spindle has a detrimental effect, serious wear plug and squeeze round, affect the product of the timber Rate and product quality.In order to effectively reduce the harmful spindle displacement during extrusion and improve the stress state of the spindle, a coupling was designed to allow axial movement of the spindle when the spindle was subjected to a small load. Practice shows that the improvement After the extruder spindle system has been greatly improved the force, plug and squeeze wheel life has greatly improved equipment performance has improved significantly, the production of finished products and pass rate have significantly improved.
