【正文】 機(jī)的設(shè)備投資回收期，并取得了良好的經(jīng)濟(jì)效益。從而推動(dòng)了我國(guó)切割行業(yè)的飛速發(fā)展。與八十年代相比，當(dāng)時(shí)國(guó)內(nèi)的大型精密數(shù)控切割 機(jī)，主要依賴進(jìn)口產(chǎn)品。目前，我國(guó)進(jìn)口的數(shù)控切割機(jī)，主要是一些技術(shù)比較先進(jìn)的產(chǎn)品。進(jìn)入新世紀(jì)以來(lái)，切割行業(yè)又有了新的發(fā)展，原來(lái)我國(guó)出口的數(shù)控切割機(jī)主要銷到一些發(fā)展中國(guó)家。它可以自動(dòng)完切割物體，使人們不必重復(fù)簡(jiǎn)單而又枯燥無(wú)味的工作?？梢哉f(shuō) 半 自動(dòng)切割機(jī)的應(yīng)用范圍是非常廣泛的，它有著非常廣闊的前景。利用摩擦力將要加工的料在膠滾的滾動(dòng)下不斷將料進(jìn)行旋轉(zhuǎn)， 從而使 其達(dá)到半自動(dòng)切割的目的。可依據(jù)加工的需要隨時(shí)調(diào)節(jié)電動(dòng)機(jī)的速度。目前，除了采用手工剪切非金屬墊片這種功效較低，廢品較多的方法外，施工企業(yè)大多自制或采購(gòu)一種單刃墊片切割機(jī)進(jìn)行墊片的加工。工作時(shí)，首先確定待加工墊片的外徑，使變徑機(jī)構(gòu)確定合適的加工直徑。而后，電動(dòng)機(jī)帶動(dòng) V帶，通過(guò)動(dòng)力傳遞機(jī)構(gòu)，使單刃刀具上下往復(fù)切割。兩次變徑加工降低了墊片加工的效率，而且需要兩次變徑和定心，增加了操作人員的工作量。 （ 2） 變徑機(jī)構(gòu)：主要由齒輪、齒條、滑軸、滑濤、變徑架、變徑搖桿等部件組成，其作用是調(diào)節(jié)加工半徑。 （ 4） 定心機(jī)構(gòu)：主要由定心軸及相關(guān)兩部件組成，其作用是確定非金屬板的圓心并使板圓周進(jìn)給。s industry, the sheet cutting process is finished the most important step. Is also an important quality assurance process finished. Cutting the use of advanced modern technology, not only can guarantee the quality of the product and raise labor productivity, but also enterprise products make a substantial decline in the manufacturing costs and shorten the production cycle of the product. With the new products, new technology, the extensive use of new technologies. Intelligent cutting precision cutting industry will bee the development trend of the future. Cutting industry in China are mainly posed of the following types of production enterprises 1) gantry cutting machine。 3) plasma cutting power supply and cut mouth。s development, its products from a single manual cutting torch to develop into a more full range of industry categories. Products to meet the basic needs of the domestic market and some products to enter the international market. In recent years, the production of CNC cutting machine, especially the rapid development of technology. Modern CNC profile cutting machine cutting is still the main, because only this way of NC cutting, in order to effectively ensure the cut in the process of fully automated processes. CNC cutting technology of our relatively late development, but its development speed very quickly. In the eighties before in our country, under the sheet material is based on manual or semiautomatic carbased cutting. Into the eighties, with the deepening of enterprise reform, it has been recognized。s rapid development of cutting industry. 張勇 ： Φ 1000 半自動(dòng)密封環(huán)切割機(jī) IV At present, the domestic production of various types of CNC cutting machine, able to meet the needs of various industries, as well as a certain number of exports. Compared with the eighties, when the domestic largescale precision CNC cutting machine, mainly relies on imported products. Since the niies, imports showed a downward trend in yearonyear. At present, China39。s exports of CNC cutting machine sales to a number of developing countries mainly. Other cutting machine manufacturing exports also gradually increase, which also marks the industry in China cutting machine cutting manufacturing level to a new level Semiautomatic cutting machine is to ring people from a single, repeated the work of liberation, and the successful development of a higher degree of automation, semiautomatic machines. It can be finished automatically cutting objects, so that people do not have to repeat the work of a simple and dull. Semiautomatic cutting machine is widely used in a variety of specifications for the processing of a circular pad, and replace manual lathe cutting a new generation of instrumentation products. It can be said that the application of semiautomatic cutting machine is a very broad scope, it has a very broad prospects. In this design, semiautomatic cutting machine is the main principle of threephase asynchronous motor as the driving force to drive the eccentric wheel to cut the processing tool movement. The use of friction material to be processed in the plastic unde
