摘 要
翅片管是金屬管外表面繞有薄鋁帶的螺旋形翅片，并利用翅片進行熱交換的換熱元件，它是目前國內(nèi)外公認的高效熱交換元件，隨著我國空調(diào)、制冷業(yè)的發(fā)展，對翅片管的需求量日益增加，同時也對產(chǎn)品功能、質(zhì)量、性價比、更新?lián)Q代周期都提出越來越高的要求。而我國現(xiàn)有的翅片管生產(chǎn)設備多屬于半機械、半手工生產(chǎn)方式，生產(chǎn)效率低，產(chǎn)品質(zhì)量不穩(wěn)定，不能滿足用戶要求。要提高翅片管生產(chǎn)設備的性能，靠進口已經(jīng)不能適應市場競爭的要求，必須針對我國的實際情況，開發(fā)滿足市場需求的翅片管自動生產(chǎn)設備。
本文在對目前國內(nèi)外翅片管生產(chǎn)設備現(xiàn)狀進行研究與分析的基礎上，對整個翅片管自動生產(chǎn)設備的設計進行了探討，通過對翅片管自動生產(chǎn)設備中的重要零部件進行計算選型及校核，完成了翅片管自動生產(chǎn)設備整體結(jié)構(gòu)設計，采用可編程控制器PLC控制步進電機實現(xiàn)不同管徑、不同長度鋼管螺距的無級變速。
本設計主要實現(xiàn)翅片管螺距的無級調(diào)速，并可實現(xiàn)程序管理。能夠有效地提高企業(yè)的生產(chǎn)效率和自動化水平，并*終提高企業(yè)在市場上的競爭力。
關鍵詞：翅片管自動生產(chǎn)設備，PLC控制電路，傳動機構(gòu)，無級調(diào)速
ABSTRACT
Finned tube is a metal tube with thin aluminum strip around the outer surface of the spiral-shaped fins, and use the heat transfer fin for heat exchange element, it is widely recognized as highly efficient heat exchange components, along with our air conditioning and refrigeration industry The development of the growing demand for finned tube, but also on product features, quality, cost-effective, replacement cycle, increasing demands are made. In China, the existing fin tube production equipment and more a semi-mechanical, semi-manual mode of production, low productivity, product quality is unstable, can not meet user requirements. To improve the performance of finned tube production equipment, rely on imports can not meet the requirements of market competition, must address the actual situation in China to develop to meet market demand for fin-tube automatic production equipment.
This article in the fin tube production equipment at home and abroad to conduct research and analysis of current situation on the basis of the fin-tube design of automated production equipment was discussed, through the fin-tube automatic production equipment, the important components in an election conducted type and check to complete the fin-tube design of the overall structure of automated production equipment, programmable controllers PLC controlled stepper motor with different diameters, different lengths of tube of continuously variable pitch.
The design of the main implementation of variable speed pitch finne
