Description
Technical Field
The invention relates to the technical field of pipe fitting processing, in particular to a pipe fitting inner wall strengthening device.
Background
The continuous increase of fuel injection pressure of high pressure common rail systems is a necessary trend in the development of fuel systems for diesel engines. The common rail pipe is used as an energy storage element of a high-pressure common rail system, and along with the improvement of injection pressure, higher requirements on the pressure bearing capacity and the strength of the common rail pipe are also provided. Generally, increasing the wall thickness of the container may increase the load bearing capacity of the container to some extent. However, for high-pressure and ultrahigh-pressure vessels, the stress distribution on the vessel wall is more uneven due to the infinite increase of the wall thickness along with the increase of the working pressure. Also, when the working pressure in the container is greater than 0.58 σ s, increasing the wall thickness does not avoid yielding of the inner wall. In addition, the increase in wall thickness undoubtedly results in material consumption, increased costs, and increased weight. Therefore, an effective method for increasing the elastic load capacity of high and ultra-high pressure vessels is to prestress the high pressure vessel wall, i.e., so-called wall strengthening. The fatigue strength of the common rail pipe can be effectively improved and the fatigue life can be prolonged by strengthening the inner wall of the common rail pipe.
The common rail pipe strengthening method comprises the steps of filling a medium in an inner cavity of the common rail pipe, applying high pressure to the inner wall in a short time to enable the inner wall of the common rail pipe to yield, enabling the inner wall of the common rail pipe to generate radially expanded residual deformation under the pressure stress, and then relieving the pressure. At this time, due to elastic shrinkage of the outer layer material of the common rail pipe, the inner layer material of the common rail pipe which is plastically deformed generates compressive stress after elastic recovery, so that residual compressive stress is obtained. When the strengthening method works, the inner cavity of the common rail pipe needs to be filled with a medium, all oil holes are sealed and pressurized, a set of precise pressurization control system is needed in the working procedure for adjusting the pressure value of the inner cavity of the common rail pipe, and a set of good sealing system is needed to prevent medium leakage of all paths of the common rail pipe in the pressurization process.
In summary, the above method has the following disadvantages: 1. the equipment is complex, the medium is ensured not to leak in the process of pressurizing the inside of the common rail pipe in the working process, and meanwhile, the pressure value in the pressurizing process is accurately controlled, so that the working procedure is complex; 2. the safety is poor, the phenomenon that the common rail pipe is suddenly burst and the medium in the common rail pipe is sprayed out can occur in the process of pressurizing the common rail pipe, the surrounding environment is polluted, and the personal safety of operators is threatened; 3. the cost is high, and the precision pressurization strengthening device and the sealing system are expensive, so that the research and development cost is increased.

The device need not to adopt accurate pressurization instrument to pressurize, when guaranteeing effectively to strengthen the inner wall of pipe fitting 100, simplifies the device structure, reduce cost, and does not have the risk that the pressurization bursts.
As shown in fig. 1, the current controller 4 is electrically connected to the first yoke controller 33 through a first lead wire 5, and is electrically connected to the second yoke controller 34 through a second lead wire 6.
The magnetic attraction force generated by the two magnetic induction coils on the stainless steel shot particles is adjusted and controlled by the current controller 4 and the corresponding magnetic yoke controller. The specific principle is as follows:
the formula of the electromagnetic attraction force is as follows: f = (B) δ /5000)2·S δ (N) (1)
Wherein F isElectromagnetic attraction force; b is δ Is the air gap flux density; s δ Is the cross-sectional area of the air gap, B δ 、S δ Are all coil parameters.
Due to phi δ ＝B δ S δ Thus, B is δ ＝Φ δ /S δ Substituting equation (1) yields:
F＝(Φ δ /5000)2/S δ (N) (2)
note: phi δ Is the air gap flux.
At small working air gaps, the leakage flux is negligible, i.e. phi δ ＝Φ 0 Meanwhile, when the magnetic circuit is not saturated yet, the magnetic resistance Rm of the magnetizer is negligible, namely Rm =0, and then Rm · I =0, then:
I·W＝2Φ·R δ (3)
wherein phi 0 The magnetic flux in the ideal state is phi, and the magnetic flux in actual operation is phi.
From equation (3), Φ = I · W/2R can be deduced δ (4)
R δ ＝δ/μ 0 S δ (5)
Wherein R is δ Diameter of energized coil, mu 0 Is a vacuum magnetic permeability.
Substituting the formula (4) and the formula (5) into the formula (2) can obtain the electromagnetic attraction force F:
F＝1.57(I·W) 2 ·S δ ·δ -2 ·10 -8 (N) (6)
wherein, I and W are ampere turn values; δ is the total length of the working air gap (cm).
The total torque M of the rotary magnetic force can be obtained:
M＝1.57(I·W) 2 ·S δ ·α -2 ·r -1 ·10 -8 (N·cm) (7)
wherein, alpha is the included angle (radian) between the magnet and the pole shoe; r is the radius of rotation (cm) of the magnet at the stroke, and the magnet and the pole shoe are both of the structure of a magnetic yoke controller which is the existing equipment.
Derived from the above formula: magnetic attraction and (I, W) 2 And S δ Is proportional to alpha 2 Is inversely proportional to r, S when the coil diameter and the number of turns are fixed δ 、α 2 And r are fixed values, and only one parameter variable is the current I, so that the magnetic attraction force F is increased along with the increase of the current applied to the electromagnetic induction coil. The size of electric current is adjusted through current controller 4, and is different when the electric current of yoke controller of flowing through, produces the different magnetic field of intensity on two electromagnetic induction coils, and then produces the magnetic attraction of equidimension not to the pill, and the numerical value of electric current can be according to the intensive requirement setting to the pipe fitting.
