Abstract
A plastic air inlet manifold comprises a group of air ducts which are welded mutually by an upper board (1), a middle board (2), a lower board (3) and an air duct cover board (4) and are communicated with an air cylinder. A welding rib (5) and a flash groove (6) which takes the effect on flash are arranged at the position of a welding surface (7) of every two adjacent components. A group of reinforcing ribs (8) are arranged inside each flash groove (6). The volume of the flash groove (6) is 1.5 to 3 times of the volume of melting stocks. The plastic air inlet manifold of the utility model, which can effectively prevent the manifold from contracting to be deformed due to the thick wall of the manifold, reduces welding difficulties, also reduces the weight of the manifold and can be widely used in various plastic air inlet manifolds.
Description
Technical field
The utility model relates to a kind of intake manifold, relates in particular to a kind of plastics air inlet manifold branch of engine.
Background technique
At present, plastic air intake manifold is widely used in motor, and the flash groove degree of depth of welding muscle is in the prior art calculated by the volume of melt during only according to friction welding, and considers that part is because of the blocked up hidden danger of bringing contraction deformation of welding muscle material.If adopt this flash groove degree of depth welding muscle material to seem blocked up, be unfavorable for welding, be easy to generate contraction deformation, changed the manifold cavity shape.
The model utility content
The purpose of this utility model is to overcome above-mentioned deficiency of the prior art, provides a kind of and welds simple and can prevent that manifold from causing the plastic air intake manifold of contraction deformation because of wall thickness.
The technological scheme that the utility model adopted is a kind of plastic air intake manifold, comprising that upper plate, middle plate, lower plate, air flue cover plate are welded to each other forms one group of intake duct that communicates with cylinder, be provided with the welding muscle at adjacent elements face of weld place in twos and play the flash groove of flash effect, make welding rigidity of soft tissues degree die down in order to solve because of deepening flash groove, it is insufficient to cause face of weld to be fitted when friction welding, and one group of stiffening rib is set in flash groove.
For preventing that manifold from causing contraction deformation because of wall thickness, the volume of described flash groove is 1.5-3 a times of melt volume.
As a kind of preferred version, described stiffening rib just is provided with one every 20-40mm.
Further, described flash groove is a double-layer structure up and down.
The beneficial effects of the utility model: on the basis of melt volume, increase the volume of flash groove, can effectively solve, can also reduce the welding difficulty, effectively reduce the weight of manifold because of expecting the thick manifold contraction deformation that causes.One group of stiffening rib is set in flash groove, solves because of deepening the problem that flash groove makes that welding rigidity of soft tissues degree dies down.
Below in conjunction with drawings and Examples the utility model is described further.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the A-A sectional view among Fig. 1.
Fig. 3 is the B-B sectional view among Fig. 2.
Among the figure: 1. upper plate, 2. in plate, 3. lower plate, 4. air flue cover plate, 5. welding muscle, 6. flash groove, 7. face of weld, 8. stiffening rib.
Embodiment
As Fig. 1, Fig. 2, shown in Figure 3, a kind of plastic air intake manifold, comprising that upper plate 1, middle plate 2, lower plate 3, air flue cover plate 4 are welded to each other forms one group of intake duct that communicates with cylinder, be provided with welding muscle 5 at adjacent elements face of weld 7 places in twos and play the flash groove 6 of flash effect, weld muscle 5 weakened in order to solve because of intensification flash groove 6 makes, it is insufficient to cause face of weld 7 to be fitted when friction welding, and one group of stiffening rib 8 is set in flash groove 4.
If adopt the degree of depth that is designed flash groove 6 by the volume of melt, welding muscle 5 seems blocked up, is easy to generate contraction deformation, is unfavorable for welding and has changed the manifold cavity shape, and for addressing this problem, the volume of described flash groove 4 is 1.5-3 a times of melt volume.For effectively solving the problem of stiffening rib 5 weakened, described stiffening rib 5 just is provided with one every 20-40mm.Be further weight reduction, described flash groove 6 is a double-layer structure up and down.
Claims (4)
1. plastic air intake manifold, comprising that upper plate (1), middle plate (2), lower plate (3), air flue cover plate (4) are welded to each other forms one group of intake duct that communicates with cylinder, flash groove (6) in that the face of weld of adjacent elements (7) is in twos located to be provided with welding muscle (5) and played the flash effect is characterized in that: one group of stiffening rib (8) is set in flash groove (4).
2. according to the described a kind of plastic air intake manifold of claim 1, it is characterized in that: the volume of described flash groove (4) is 1.5-3 a times of melt volume.
3. according to the described a kind of plastic air intake manifold of claim 1, it is characterized in that: described stiffening rib (8) just is provided with one every 20-40mm.
4. according to the described a kind of plastic air intake manifold of claim 1, it is characterized in that: described flash groove (4) is double-layer structure up and down.
