Description
本发明属于冶金机械领域，适用于钢材、铜材、铝材轧制机械的轧辊。The invention belongs to the field of metallurgical machinery and is suitable for rolls of steel, copper and aluminum rolling machines.
金属材料的轧制通常使用整体轧辊。其缺点在于：The rolling of metal materials usually uses solid rolls. Its disadvantages are:
①材料的浪费大。轧辊经多次修复使用，直径减小到最终须报废时，所废弃的材料大于整个轧辊的60％。①The waste of materials is large. The roll has been repaired and used for many times, and when the diameter is reduced to the point where it must eventually be scrapped, the discarded material is greater than 60% of the entire roll.
②轧辊所用材料不易选择。采用高合金材料，轧辊造价过高；采用低合金材料，轧辊使用寿命又过短。采用双金属复合铸造，由于轧辊截面尺寸较大，致使热处理的冷却速度太慢，从而轧辊表层的硬化层深度不够，高合金材料的性能得不到充分的发挥。② It is not easy to choose the material used for the roll. Using high-alloy materials, the cost of the rolls is too high; using low-alloy materials, the service life of the rolls is too short. With bimetal composite casting, due to the large cross-sectional size of the roll, the cooling rate of the heat treatment is too slow, so the depth of the hardened layer on the surface of the roll is not enough, and the performance of the high-alloy material cannot be fully exerted.
金属材料的轧制已有的组合轧辊，是由芯轴、辊套、传动键、螺母组合而成。其缺点在于：The existing combination roll of the rolling of metal material is made up of mandrel, roll sleeve, transmission key, nut. Its disadvantages are:
①芯轴与辊套为相互组合，各开有一个键槽。键槽不但使辊套的局部厚度减小，而且键槽的尖角处易产生应力集中，使辊套容易产生裂纹。因此辊套不能承受轧制过程中的较大交变应力，辊套的直径大小以及用材的选择都受到限制。①The mandrel and the roller sleeve are combined with each other, and each has a keyway. The keyway not only reduces the local thickness of the roller sleeve, but also easily produces stress concentration at the sharp corner of the keyway, which makes the roller sleeve prone to cracks. Therefore, the roll sleeve cannot withstand the large alternating stress in the rolling process, and the diameter of the roll sleeve and the selection of materials are limited.
②尺寸大的螺母装卸困难。② It is difficult to install and remove nuts with large dimensions.
③键槽和螺母的加工繁复。③ The processing of keyways and nuts is complicated.
本发明的目的在于设计一种加工简单、装卸方便、使用可靠、可承受较大交变应力的组合轧辊。The purpose of the present invention is to design a combination roll which is simple in processing, convenient in loading and unloading, reliable in use, and capable of withstanding relatively large alternating stress.
本发明上述目的的达到，采用的技术方案是：轧辊由芯轴1、辊套2、定位楔4、定位套3构成，芯轴1的一端有一个定位台阶6，另一端有一个定位台阶7和环型定位凹槽5；辊套2加热膨胀后装在芯轴1上，冷却后与芯轴1牢固组合，依靠接触面的摩擦力传送力矩；两件或多件定位楔4放入芯轴1的凹槽5中，阻止辊套2的轴向位移：定位套3加热膨胀后装在定位台阶7上，冷却后与芯轴1牢固组合，定位套3的一部分卡住定位楔4，阻止定位楔4的径向位移。To achieve the above object of the present invention, the technical solution adopted is: the roll is composed of a
本发明热装辊套式组合轧辊与已有技术相比，具有以下优点：Compared with the prior art, the heat-loaded roll sleeve combined roll of the present invention has the following advantages:
①热装辊套式组合轧辊无键槽、无螺纹，达到了加工简单、能够承受较大交变应力的目的；①Hot-loading roller sleeve combination roller has no keyway and no thread, which achieves the purpose of simple processing and can withstand large alternating stress;
②采用感应线圈局部加热，达到了装卸方便的目的；②Using induction coil for local heating, which achieves the purpose of convenient loading and unloading;
③芯轴1上的定位台阶6、7和定位凹槽5与定位楔4、定位套3共同作用，达到了辊套使用可靠的目的。③ The positioning steps 6, 7 and the
④热装辊套式组合轧辊的辊套2可用高硬度的高合金钢制作，也可以用高合金铸铁制作，辊套的外径可达300～600mm，轧辊的使用寿命可提高2倍以上，降低成本30％。④ The
