在實(shí)踐出產(chǎn)過程中，無縫異型鋼管的彎曲成形是異型管制作中最首要的一道工序。其加工方法多種多樣，如今我們選用較多的有手工壓形、模具壓形和彎管機(jī)彎形等方法：手式壓形最常用的設(shè)備之一為手動(dòng)液壓機(jī)，無縫異型鋼管廠家有單柱式和四柱式液壓機(jī)等。這種加工方法活絡(luò)，適用范圍廣，對(duì)一些三給或多曲率組合的異型管件比照有用，但功率低，人工工作量大，曲線不光滑。所以我們首要運(yùn)用手工成形進(jìn)行修改工序及試制產(chǎn)品的出產(chǎn)；
In the production process, the bending of seamless special-shaped steel tube is the most important process in the production of special-shaped tube. Its processing methods are various. Now we choose many methods such as manual pressing, die pressing and bending of pipe bending machine. One of the most commonly used equipment for manual pressing is manual hydraulic press. Seamless special-shaped steel pipe manufacturers have single-column and four-column hydraulic press. This method is flexible and applicable to a wide range of applications. It is useful for some special-shaped pipe fittings with three or more curvatures, but it has low power, large workload and non-smooth curves. Therefore, we mainly use manual forming to modify the process and trial-produce the product.
模具成形技能是選用四柱式壓力機(jī)，設(shè)備不一樣曲率的模具，約束矩形冷彎型異形管成形，首要運(yùn)用于曲率較小的構(gòu)件，如側(cè)立柱等。異形管的彎曲力和回彈力由于多種要素的影響，很難作精確的計(jì)算。成形模具一般選用閱歷公司計(jì)算與實(shí)測(cè)相結(jié)合的方法進(jìn)行計(jì)劃調(diào)整。成形技能的特點(diǎn)是功率高，合適批量出產(chǎn)，缺點(diǎn)是對(duì)異型管的原料懇求高，回彈要一起；模具約束不一樣批次的材料，回彈不一，難以調(diào)整。模具成形技能對(duì)于加工曲率半徑大的構(gòu)件比照適合，一些批量較大并且通用性較強(qiáng)的零部件我們可以選用模具或土胎成形；
Die forming skill is to select four-column press, which has different curvature and restricts the forming of rectangular cold-formed special-shaped tubes. It is mainly used for components with smaller curvature, such as side columns. The bending force and springback force of special-shaped tubes are difficult to calculate precisely because of the influence of many factors. Forming dies are usually adjusted by the combination of experience company calculation and actual measurement. The forming skills are characterized by high power and suitable mass production, but the shortcomings are high appeal for the raw materials of special-shaped tubes, and the springback needs to be together; the materials with different batches of die constraints have different springback, which is difficult to adjust. Die forming skills are suitable for processing components with large radius of curvature. Some parts with large batches and strong versatility can be formed by dies or earthen tyres.
對(duì)于小曲率半徑的異型管件，選用手工成形或模具成形都難以習(xí)氣大批量出產(chǎn)，我們運(yùn)用的數(shù)控彎管機(jī)就能滿足這種異型管的懇求。數(shù)控彎管機(jī)的自動(dòng)化程度高、功率高，能習(xí)氣各種不一樣的曲率的異型管出產(chǎn)。一般不需要投入許多的模具，運(yùn)用方便。彎出的異型管與樣板的貼合度一般不大于2mm。為了保證異型管的制作精度，一般都添加一道人工整形工序。選用專用的整形臺(tái)面等，經(jīng)整形后，異型管件與樣板不貼合度應(yīng)在1mm以內(nèi)。
For the special-shaped pipe parts with small radius of curvature, it is difficult to produce in large quantities by hand or by die forming. The NC pipe bender we use can satisfy the request of the special-shaped pipe. CNC pipe bender has high automation and power, and can be used to produce special-shaped pipes with different curvatures. Generally, it does not need to invest a lot of moulds, so it is convenient to use. The fitting degree between the bended special-shaped tube and the sample is generally not more than 2 mm. In order to ensure the manufacturing accuracy of special-shaped pipes, an artificial shaping process is usually added. Select special shaping table and so on. After shaping, the non-conformity between the special-shaped pipe fittings and the sample should be within 1 mm.
