Abstract
The invention relates to a plastic intake manifold of an engine. The plastic intake manifold is divided into an upper piece and a lower piece, the two of which are formed through vibrating friction welding, wherein one piece is provided with a frictional rib at the welding position, while the other piece is provided with a fusion welding rib at the welding position; and flash grooves are formed on both sides of the fusion welding rib. The plastic intake manifold is characterized in that the cross section of the fusion welding rib is a trapezoidal structure. Such a structure is provided with the fusion welding rib with the trapezoidal section, so that the volume of the flash groove on a side close to an inner gas path is greater than that of the traditional structure; therefore, the flash groove is capable of receiving more hot melts, thereby preventing flashes from being formed in the inner gas path of the intake manifold; and the surface fineness of the inner gas path of the intake manifold is ensured.
Description
Technical field
The present invention relates to the intake manifold of motor, be specifically related to a kind of plastics air inlet manifold branch of engine.
Background technique
Intake manifold is the important spare part of motor, and its effect is that each cylinder that air or fuel-air mixture are assigned to motor is uniformly participated in burning.At present, the performance of plastics composite improves constantly, and can satisfy the performance requirement of engine intake manifold, and therefore a lot of motor car engines have adopted plastic air intake manifold.
Adopt burst vibration friction welding moulding mostly at the process aspect plastic air intake manifold.Because of the vibration friction welding need melt away a part of material, the welding back easily promptly forms flash at the inner residual certain hot-melt object of air flue, referring to Fig. 1, and common plastics intake manifold welding portion, last slice friction ribs 1 arranged, following sheet has melting welding muscle 2, is the rectangular cross-section, and melting welding muscle 2 both sides have flash groove 3 less relatively, the meeting that flash has overflows to interior airway surface, directly influence airway surface degree of finish in the intake manifold, reduce the motor charging efficiency, thereby influence engine performance.
Summary of the invention
The present invention proposes a kind of plastics air inlet manifold branch of engine, mainly solves traditional intake manifold welded structure after the vibration friction welding, and interior air flue easily forms the problem of flash.
Technological scheme of the present invention is as follows:
A kind of plastics air inlet manifold branch of engine, it is divided into two up and down, and by vibration friction welding moulding, wherein a slice has friction ribs in the welding part, and another sheet has the melting welding muscle in the welding part, and there is flash groove on melting welding muscle both sides; It is characterized in that: the cross section of described melting welding muscle is a trapezium structure.
This structure is owing to adopted trapezoid cross section melting welding muscle, make the flash groove volume of inner air flue one side greater than traditional structure thus, can hold more hot-melt object, just can avoid air flue formation flash in intake manifold, guarantee airway surface degree of finish in the intake manifold.
Description of drawings
Fig. 1: existing welded structure weldering section front view with melting welding muscle of rectangular cross-section.
Fig. 2: the welded structure weldering section front view of the melting welding muscle of trapezoid cross section of the present invention.
Fig. 3: trapezoid cross section melting welding muscle welded structure postwelding sectional view of the present invention.
Embodiment
Referring to Fig. 2, two were welded about plastic air intake manifold was divided into, position in the needs welding, keep the structure of last slice friction ribs 1 constant, with common welded structure is the melting welding muscle 4 that the melting welding muscle of rectangular cross-section is designed to the trapezoid cross section, the sectional area of the sectional area of the melting welding muscle 4 of trapezoid cross section and the melting welding muscle 2 of former rectangular cross-section identical (promptly equaling S2 among Fig. 2 as the S1 among Fig. 1).
As shown in Figure 3, the melting welding muscle 4 of trapezoid cross section will be stored in the flash groove 3 because of vibrating fricative hot-melt object 5 during welding, and 6 are the melting welding volume among the figure.Because flash groove 3 volumes of the interior air flue side of this structure are greater than traditional flash groove volume, thereby be the flash groove of this welded structure air flue side in intake manifold can hold more flash can not appear in air flue the situation of flash is arranged, thereby airway walls is smooth in can guaranteeing.
This welded structure has improved the charging efficiency of intake manifold, helps improving economy, the power performance of motor.
