钻杆螺旋边成型机总体设计

摘要

本设计主要对钻杆螺旋边卷绕机进行了较全面论述，了解了缠绕机 的类型、发展现状。阐明了卷绕机的工作原理、组成及其特性。并根据 螺卷绕机的工作原理、工作条件、工作要求等设计一卷绕机。在此过程 中，经过对比结合，初步确定了合适的卷绕机结构形式。 在计算中，首 先确芯轴的尺寸，然后通过对该尺寸计算校核，选择出其他部件的外形 尺寸，再对其进行校核，确定是否能达到设计要求。. 由于芯轴在卷绕 过程中受力较复杂。本设计从这个问题出发，通过芯轴的动力学模型对 其受力过程进行分析.同时，利用分析问题的结果再综合其他因素，最终 选取合适的电动机、减速器和联轴器。接下来的设计包括对主轴组件的 设计校核，对送料压轮的设计校核，对连接接键及转盘的强度校核，对 支承轴的命、前后支架轴承端盖及套杯的设计和优化。

最后对钻杆螺旋边卷绕机的安装和平时保养做了总结，整个设计对 今后的设计工作将有实际指导意义和价值。

Abstract

This design on the drill pipe spiral side winding machine, discussed in a more comprehensive understanding of a winding machine type, development status. Clarifies the working principle of the winding machine, the composition and characteristics. And in accordance with the working principle of the spiral winding machine, working conditions, job requirements and the design of a winding machine. In this process, after the contrast combination, initially identified a suitable winding machine structure. In the calculation, first determine the mandrel size, then by the size calculation checking, select the other components Dimensions, and then its check to determine whether it can meet the design requirements. Force due to the mandrel in the winding process is more complex. This design, starting from this issue, and analyzed by the dynamic model of the mandrel force. The same time, the results of the analysis of the problem and then combined with other factors, and ultimately select a suitable motor, speed reducer and coupling. Next, the design includes the spindle component design verification, the design of the feed pressure round of design checking, checking the strength to connect the access key and dial the life of the supporting shaft, front and rear bracket bearing cover and cup set and optimization.

Finally, the installation and normal maintenance of the drill pipe spiral edge of the winding machine to do the entire design for the future design work will have practical guidance on the meaning and value.

Key words:Spiral side winding machine Mandrel Check principle
