Description

一种分配管及其加工工艺、和发动机高压油轨总成Distributing pipe and its processing technology, and engine high-pressure fuel rail assembly

技术领域Technical field

本发明涉及一种发动机的部件，尤其涉及一种分配管及其加工工艺、和发动机高压油轨总成。The invention relates to an engine component, in particular to a distribution pipe and its processing technology, and an engine high-pressure fuel rail assembly.

背景技术Background technique

油轨的作用：以汽油发动机为例，汽油发动机有多个气缸，且每个气缸都独立装有喷油器以提供汽油，所有喷油器连接在一根公用的油管上(简称燃油共轨)。工作原理是先由油泵将汽油按一定的压力从油箱输送进入油轨，油轨内部有一个恒定的工作压力将汽油送入每个喷油器，喷油器通过电控装置将汽油按要求喷射进入气缸内进行燃烧。油轨独立与汽油发动机之外，在整个喷射燃烧过程中保持不变。The role of the fuel rail: Take the gasoline engine as an example. The gasoline engine has multiple cylinders, and each cylinder is independently equipped with an injector to provide gasoline. All the injectors are connected to a common fuel pipe (referred to as fuel common rail). ). The working principle is that the oil pump first transports gasoline from the fuel tank into the fuel rail at a certain pressure. There is a constant working pressure inside the rail to send gasoline to each fuel injector. The fuel injector injects gasoline as required through the electronic control device Enter the cylinder for combustion. The fuel rail is independent of the gasoline engine and remains unchanged throughout the injection combustion process.

高压油轨：将燃油直接喷射入气缸内，利用气缸内的高压气流使汽油充分雾化达到汽油充分燃烧的目的。由于汽油被充分燃烧，所以其燃油的经济性能大大的提高，其二氧化碳排放明显降低，使得高压燃油发动机的性能有着极佳的表现，是目前国际上广泛采用的汽油发动机技术。High-pressure fuel rail: Fuel is directly injected into the cylinder, and the high-pressure air flow in the cylinder is used to fully atomize the gasoline to achieve the purpose of full combustion of the gasoline. Since gasoline is fully burned, the economic performance of its fuel is greatly improved, and its carbon dioxide emissions are significantly reduced, which makes the performance of high-pressure fuel engines have excellent performance, and it is currently widely used in international gasoline engine technology.

目前国际上的高压汽油发动为了在提升性能的同时节能降耗，主流方法是不断提高整个发动机的工作压力和强度，对于高压油轨本身的性能要求也越来越高，尤其对于用于发动机高压油轨总成的分配管的密封性及耐压性要求也越来越高，现有分配管内部的内腔2通常为通孔(详见图1和图2和图3)，内腔2通孔一端为开口，内腔2通孔另一端以封堵盖3配合第二无氧铜环4在分配管本体1内部进行分体式堵塞，形成密封端面，但是在封堵盖3与分配管本体1内壁之间、第二无氧铜环4与分配管本体1内壁之间均不可避免地存在缝隙(即泄露风险点5)，这些缝隙在高压情况下易产生汽油泄露，减低汽油使用率的同时还可能造成汽车其他部件损害，因此如何避免分配管的密封端面泄露汽油(尤其是在分配管内部高压的情况下)成为需要解决的问题。At present, the international high-pressure gasoline engine is launched in order to improve performance while saving energy and reducing consumption. The mainstream method is to continuously improve the working pressure and strength of the entire engine. The performance requirements for the high-pressure fuel rail itself are also getting higher and higher, especially for the high-pressure engine. The distribution pipe of the oil rail assembly also requires higher sealing and pressure resistance. The inner cavity 2 of the existing distribution pipe is usually a through hole (see Figures 1 and 2 and 3 for details), and the inner cavity 2 One end of the through hole is an opening, and the other end of the inner cavity 2 through the blocking cap 3 cooperates with the second oxygen-free copper ring 4 to split the inside of the distribution tube body 1 to form a sealed end face, but the blocking cap 3 and the distribution tube There are inevitably gaps between the inner wall of the body 1 and between the second oxygen-free copper ring 4 and the inner wall of the distribution pipe body 1 (that is, leakage risk point 5). These gaps are likely to cause gasoline leakage under high pressure and reduce gasoline utilization. At the same time, it may also cause damage to other parts of the car, so how to avoid leakage of gasoline at the sealing end surface of the distribution pipe (especially in the case of high pressure inside the distribution pipe) has become a problem that needs to be solved.

另外，目前现有分配管的传统加工方法制作工艺(比如，热轧(挤压无缝钢管)：圆管坯→加热→穿孔→三棍斜扎、连轧或挤压→脱管→定径(或减径)→冷却→矫直→水压试验(或探伤)→标记→入库；或冷拔(轧)无缝钢管：圆管坯→加热→穿孔→打头→退火→酸洗→涂油(镀铜)→多道次冷拔(冷轧)→坯管→热处理→矫直→水压试验(探伤)→标记→入库)复杂、过程耗能高、经济性差，废料回收利用率不高，资源浪费率高，同时还需要化学清洗，环境污染度高。In addition, at present, the traditional processing method of the existing distribution pipe manufacturing process (for example, hot rolling (extruded seamless steel pipe): round tube billet → heating → perforation → three-roller diagonal lashing, continuous rolling or extrusion → de-pipe → sizing (Or diameter reduction)→cooling→straightening→hydraulic test (or flaw detection)→marking→storage; or cold drawing (rolling) seamless steel pipe: round tube billet→heating→perforation→heading→annealing→pickling→coating Oil (copper plating) → multi-pass cold drawing (cold rolling) → billet tube → heat treatment → straightening → hydraulic test (flaw detection) → marking → storage) complex, high energy consumption in the process, poor economy, waste recycling rate Not high, the rate of waste of resources is high, chemical cleaning is also required, and the degree of environmental pollution is high.
