2600mm中板矫正机设计

摘要

随着生产技术的进步和现代化改造的实施，中厚板生产向着高效化、高质量的方向发展，对厚度在4~60 mm的常规产品，各生产单位均采用了线上的多辊矫正设备，为了满足日益提高的板形、板面质量要求，多辊矫正设备得到了进一步的发展。因此，我对矫正机进行相应的设计，以降低成本，提高效率、产量和质量来满足生产及客户的要求。本篇论文中，首先论述了矫正机的背景与发展状况，以及未来的发展趋势，并根据当前实际情况，考虑经济性和效率性等相关因素，对相关设备做了合理选用；然后对本次设计的中厚板矫正机进行了相应的设计。该矫正机用于中厚板生产线，为四重十一辊矫正，采用机械压下，机架为预应力机架。在设计计算中，首先，确定了主传动系统的结构参数，并根据矫正力、矫正力矩和主电机功率及工作特点选择主传动系统的电机类型和型号；其次，确定了压下系统的结构参数，并根据驱动压下螺丝的驱动力矩和电机功率选择压下电机的类型和型号；再次，对压下系统蜗轮蜗杆减速机进行了设计与校核；再次，对工作辊的强度和轴承的寿命进行了相应的校核；最后，讨论了润滑方式以及设备环保经济可行性分析等内容。

The Design of the 2600mm Plate Straightening Machine

Abstract

With the development of technology and the implement of Modernization, production of plate straightening moves towards efficient and high quality direction. For thikness of 4~60mm conventional Products, every production department adopts Multi-roll correction equipment. In order to meet the requirements of ever-inceasing plate types and quality of boards, the multi-roll correction equipment gets improved. Now we are studying and designing the straightening machine to reduce costs and improve efficiency, output and quality, meeting the requirements of production and our customers.In this thesis. Background, deveopment status and trend of straightening machine were firstly discussed and according to the present situation, considering economy and efficiency-related factors, I select some related equipment reasonablely and then have a corresponding design of the plate straightening machine. This straightening machine is used in plate straightening machine production line, choosing reversible straightening for 11 four-roll and with mechanical pressure and prestressed rack. In the design of calculating, firstly make sure the main drive system and according to the straightening force, correct torque, the main motor power and work characteristics, we choose types and models for the main drive system; then plan and check the reduction worm reducer system; next check the intensity of work roll and life-span of bearing; lastly, make sure ways of lubrication as well as economic feasibility analysis of equipment.
