Description

A kind of distribution pipe and its processing technology and engine high pressure oil rail assembly

Technical field

The present invention relates to a kind of component of engine more particularly to a kind of distribution pipe and its processing technology and engine are high Pressure oil rail assembly.

Background technique

The effect of oily rail: by taking petrol engine as an example, petrol engine has multiple cylinders, and each cylinder is independently equipped with For fuel injector to provide gasoline, all fuel injectors are connected on a common oil pipe (abbreviation fuel common-rail).Working principle is first Gasoline is delivered into oily rail from fuel tank by certain pressure by oil pump, has a constant operating pressure by gasoline inside oily rail It is sent into each fuel injector, gasoline is injected into cylinder by fuel injector as required by electric control gear to burn.Oily rail is independent Except petrol engine, remained unchanged during entire spray combustion.

High pressure oil rail: fuel oil is injected directly into cylinder, is atomized gasoline sufficiently using the high pressure draught in cylinder and is reached To the clean-burning purpose of gasoline.Since gasoline is sufficiently burned, so the economic performance of its fuel oil greatly improves, dioxy Change carbon emission to be substantially reduced, so that the performance of high pressure fuel engine has splendid performance, it is to be widely used in the world at present Gasoline engine technology.

Current international high pressure gasoline is started in order to energy-saving while improving performance, and main stream approach is constantly to mention The operating pressure and intensity of high entire engine, it is also higher and higher for the performance requirement of high pressure oil rail itself, particularly with Also higher and higher, available engine high pressure oil rail is required in the leakproofness and resistance to pressure of the distribution pipe of engine high pressure oil rail assembly Inner cavity 2 in assembly inside distribution pipe is usually through-hole (being detailed in Fig. 1, Fig. 2 and Fig. 3), and 2 through-hole one end of inner cavity is opening, inner cavity 2 The through-hole other end cooperates the first anaerobic copper ring 12 to carry out split type connection inside distribution tube body 1 with Separated pipe joint 11, But between Separated pipe joint 11 and distribution 1 inner wall of tube body, between the first anaerobic copper ring 12 and distribution 1 inner wall of tube body It is inevitably present gap (i.e. disclosure risk point 5), these gaps are also easy to produce gasoline leakage under high-pressure situations, lower vapour It may also result in the damage of automobile other component while oily utilization rate, therefore the seal face of distribution pipe how to be avoided to reveal gasoline (especially in the case where distribution pipe internal high pressure) becomes problem to be solved.

In addition, the traditional diamond-making technique manufacture craft of existing distribution pipe is (for example, hot rolling (squeezing seamless steel pipe): circle at present Pipe → heating → perforation → tri- rods are tiltedly pricked, tandem rolling or extruding → de- pipe → sizing (or tube reducing) → cooling → aligning → hydraulic pressure try Test (or flaw detection) → label → storage；Or seamless steel pipe (is rolled) in cold-drawn: circular pipe blank, and → heating →, which perforates, → taking the lead → anneals → acid Wash → oiling (copper facing) → multi-pass cold-drawn (cold rolling) → base pipe → heat treatment → aligning → water pressure test (flaw detection) → label → Storage) it is complicated, process energy consumption is high, less economical, waste recovery utilization rate is not high, and resource waste rate is high, while also needing chemistry Cleaning, environmental pollution degree are high.
