【摘要】：钢管的产量的每年都在增加,市场上对钢管加工精度的需求不断提高,市场需要的钢管外径、壁厚的规格不断增大,这就要求对钢管进行倒棱、平端面的钢管倒棱机要能跟上目前的市场需求。而国内的钢管倒棱机对钢管规格的加工范围比较小,加工精度不高,随着时间的推移,这种矛盾逐年增加。在这种生产技术的发展赶不上生产需求的情况下,本文所研究的新型钢管铣头倒棱机具有重大的意义。本文在一下几个方面对新型全自动钢管铣头倒棱机进行了详细的设计:1.在机械结构方面,新型全自动钢管铣头倒棱机是对传统的平头倒棱机的机械结构进行了改进,加入了自转系统,铣刀和倒棱刀在随大盘转动的过程中,可进行自转。与传统平头倒棱机相比,钢管由车削加工变为铣削加工,提高了钢管加工表面质量;设备加工范围得到了扩大;减小了切削力和切削功率。2.对新型钢管铣头倒棱机的动力系统的参数进行了计算,包括加工钢管规格范围的计算、铣刀的选择、铣端面和倒棱加工参数的计算、铣刀主轴动力齿轮传递的计算、铣刀轴向进给机构的计算、铣刀径向进给机构和大盘以及铣刀电机的选择。3.使用Solidworks对新型钢管铣头倒棱机各部分机构进行了建模,选用有限元软件Ansys对其进行了静力分析和模态分析,其中重点对铣刀主轴部分进行了应力的计算和模态分析。4.对新型钢管铣头倒棱机的控制部分进行了设计,进给系统采用闭环控制系统,分析了在整个加工过程中的干扰源。5.对本文所研究的内容进行了总结,得出本文设计的新型钢管铣头倒棱机符合现有的加工条件,指出本文的不足之处,并展望以后的研究方向。
[Abstract]:The output of steel pipe is increasing every year, the demand for steel pipe processing precision is increasing, the outer diameter of steel pipe and the specification of wall thickness are increasing, which requires the chamfering of steel pipe. The steel pipe chamfering machine with flat face can keep up with the current market demand. However, the domestic steel pipe chamfering machine has a relatively small processing range to the steel pipe specification, and the machining accuracy is not high, with the passage of time. This kind of contradiction increases year by year. When the development of this kind of production technology can not keep up with the production demand. The new type of steel pipe milling head chamfering machine studied in this paper is of great significance. In this paper, a new type of automatic steel pipe milling head chamfering machine is designed in detail in the following several aspects. The new type of automatic steel pipe milling chamfering machine is an improvement on the mechanical structure of the traditional flat-head chamfering machine, with the addition of the rotation system, the milling cutter and the chamfering cutter in the process of turning with the large plate. Compared with the traditional flat-head chamfering machine, the steel pipe is turned from turning to milling, which improves the surface quality of steel pipe. The processing range of the equipment has been expanded; The cutting force and cutting power are reduced. 2. The parameters of the power system of the new steel pipe milling head chamfering machine are calculated, including the calculation of the steel pipe specification range and the selection of the milling cutter. The calculation of milling end face and chamfering parameters, the calculation of the dynamic gear transfer of the milling cutter spindle, the calculation of the axial feed mechanism of the milling cutter. The selection of milling cutter radial feed mechanism, large disk and milling cutter motor. 3. Using Solidworks to model each part of the new steel pipe milling head chamfering machine. The static analysis and modal analysis of the finite element software Ansys are carried out. The stress calculation and modal analysis of the main shaft part of the milling cutter are emphasized. 4. The control part of the new steel pipe milling head chamfering machine is designed, and the closed-loop control system is used in the feed system. The interference source in the whole process is analyzed. 5. The contents of this paper are summarized, and the new type of steel pipe milling chamfering machine designed in this paper accords with the existing processing conditions, and points out the shortcomings of this paper. The future research direction is prospected.
