【摘要】：目前市場上托輥的加工設(shè)備有很多,但大部分都是手工操作的單機(jī),這種傳統(tǒng)的手工操作工作量大、慢、容易出錯,已不能適應(yīng)現(xiàn)在快速變化的市場。國內(nèi)的托輥生產(chǎn)線基本都是半自動化的模式,即把加工設(shè)備按照工藝流程的位置擺放,然后由人工操作機(jī)床,上下料靠吊車或者手動完成。國外的托輥生產(chǎn)技術(shù)發(fā)展較快,生產(chǎn)線的自動化程度非常高,但是進(jìn)口的托輥生產(chǎn)線的價格非常昂貴,而且后期的維護(hù)維修也十分困難,只有國內(nèi)極少數(shù)的企業(yè)引進(jìn)了國外的托輥生產(chǎn)線,因此開發(fā)適合我國國情的托輥?zhàn)詣踊a(chǎn)線具有重大意義。TG-ZX01托輥加工及裝配自動化生產(chǎn)線是國內(nèi)第一條自主研發(fā)的托輥加工及裝配自動化生產(chǎn)線,全線實(shí)現(xiàn)加工裝配自動化、工件輸送自動化及調(diào)整自動化,是具有高科技含量的柔性化的加工生產(chǎn)自動線。本文研究TG-ZX01托輥加工及裝配自動化生產(chǎn)線主要從以下幾個方面進(jìn)行：(1)分析對比了國內(nèi)外托輥生產(chǎn)設(shè)備的現(xiàn)狀以及發(fā)展趨勢。(2)介紹鋼制托輥的結(jié)構(gòu)、分類、用途以及加工裝配要求。(3)結(jié)合目前鋼制托輥的生產(chǎn)加工工藝,總結(jié)了一套新的托輥工藝流程,并據(jù)此工藝流程設(shè)計(jì)出生產(chǎn)線總體方案,確定生產(chǎn)線布局,并對生產(chǎn)線進(jìn)行了平衡設(shè)計(jì)。通過平衡的設(shè)計(jì)可以促進(jìn)整個生產(chǎn)系統(tǒng)的人員配置,物流運(yùn)輸,信息傳遞更加順暢,降低了人員,物流的成本,提高整條生產(chǎn)線空間和時間的利用率,提高了整個生產(chǎn)過程的生產(chǎn)效率,幫助企業(yè)降低成本,提高整體生產(chǎn)效益。(4)對生產(chǎn)線采用的新技術(shù)新工藝進(jìn)行研究分析,對生產(chǎn)線生產(chǎn)的托輥進(jìn)行精度分析。論文在分析托輥各部分結(jié)構(gòu)的基礎(chǔ)上,總結(jié)了托輥各部件加工以及整體裝配的要求,對各工序加工分別提出了工藝改進(jìn)與設(shè)計(jì)分析。并綜合了目前加工托輥設(shè)備的研究成果,將獨(dú)創(chuàng)的托輥卡圈壓裝技術(shù)、軸承座無止口壓裝工藝、精度綜合檢測技術(shù)等應(yīng)用到生產(chǎn)線中。最終研制開發(fā)出一條全自動化的托輥加工與裝配生產(chǎn)線。該項(xiàng)目是國家的重點(diǎn)項(xiàng)目,獲得了國家的首臺套認(rèn)證,并已交付用戶使用,生產(chǎn)線生產(chǎn)的托輥各項(xiàng)指標(biāo)均達(dá)到國家標(biāo)準(zhǔn)GB1059-89的規(guī)定,滿足了用戶的要求,給用戶帶來了巨大的經(jīng)濟(jì)收益和社會效益。
[Abstract]:At present, there are a lot of processing equipments of roller in the market, but most of them are single machines operated by hand. This kind of traditional manual operation is heavy, slow and error-prone, so it can not adapt to the rapidly changing market now. The domestic roller production line is basically semi-automatic, that is, the processing equipment is placed in accordance with the technological process, and then manually operated machine tools, loading and unloading by crane or manual completion. Overseas roller production technology is developing rapidly, and the automation of production line is very high, but the price of imported roller production line is very expensive, and the maintenance and maintenance of the later stage is very difficult. Only a very small number of domestic enterprises have introduced overseas roller production lines. Therefore, it is of great significance to develop the automatic production line of roller for our country. TG-ZX01 automatic production line of roller processing and assembly is the first automatic production line of roller processing and assembly developed independently in China, and the whole line realizes the automation of processing and assembly. Workpiece transportation automation and adjustment automation is a flexible automatic line of processing and production with high-tech content. This paper studies the automatic production line of TG-ZX01 roller processing and assembly mainly from the following aspects: (1) the present situation and development trend of domestic and foreign roller production equipment are analyzed and compared. (2) the structure and classification of steel roller are introduced. Application and assembly requirements. (3) combined with the current production and processing technology of steel rollers, a new process of roller is summarized, and the overall production line scheme is designed according to the technological process, and the layout of production line is determined. The balance design of the production line is also carried out. Through balanced design, it can promote the staffing of the whole production system, logistics transportation, information transmission more smooth, reduce the cost of personnel, logistics, improve the overall production line space and time utilization, It improves the production efficiency of the whole production process, helps the enterprise to reduce the cost, and improves the overall production efficiency. (4) the new technology and new technology used in the production line are studied and analyzed, and the precision of the rollers produced in the production line is analyzed. On the basis of analyzing the structure of each part of the roller, this paper summarizes the requirements of the parts processing and the whole assembly of the roller, and puts forward the process improvement and design analysis for each working procedure. Based on the research results of the current processing roller equipment, the original roller card ring pressing technology, bearing non-stop pressing technology, precision comprehensive testing technology and so on are applied to the production line. Finally, a fully automatic production line of roller machining and assembly is developed. The project is one of the key projects in the country. It has obtained the first set of certification of the country, and has been delivered to the users for use. All the indicators of the rollers produced in the production line meet the requirements of the national standard GB1059-89 and meet the requirements of the users. It brings huge economic and social benefits to users.
