Abstract
The utility model belongs to pipe working machinery technical field, discloses the outlet of a kind of internal-combustion engine and exhaust gear joint steel pipe.Its technical characteristics: be made up of the steel pipe being provided with stiffening rib and the flange plate that is welded in end, stiffening rib is that several axial distribution are on tube wall and with it for the arc being integrally connected structure is rectangular.The tube wall forming the Steel pipe end surface axis of this joint steel pipe is distributed with and does stiffening rib for the arc being integrally connected structure is rectangular with it, namely stiffening rib is the inalienable part of steel pipe, substantially increase join strength between the two, namely no matter internal-combustion engine occurs, and trembling of sample both can not be separated, and therefore improves the working life of joint steel pipe.
Description
Technical field
The utility model belongs to joint steel pipe technical field, relates to the outlet of a kind of internal-combustion engine and exhaust gear joint steel pipe concretely.
Background technique
The joint steel pipe (as shown in Figure 1, 2) being installed on diesel oil or gasoline engine outlet and exhaust gear is made up of with the flange plate 3 being welded in end the steel pipe 2 being provided with stiffening rib 1 on its external wall, namely the flange plate of this joint steel pipe is connected with the internal-combustion engine of dither, and opposite side is connected with exhaust gear.During use, due to the dither of internal-combustion engine, be welded in the shaft orientation reinforcing rib outside steel pipe and weld between end with flange plate, to improve its join strength.But the stiffening rib of above-mentioned joint steel pipe is directly welded on flange plate side and outer wall of steel pipe, this joint steel pipe structural strength is lower, in use soldering point 4(also i.e. stress point) the as easy as rolling off a log damage fracture in place causes damage, and causes the inefficacy of joint steel pipe.
Model utility content
The purpose of this utility model is just to provide the internal-combustion engine outlet and exhaust gear joint steel pipe that a kind of stiffening rib and joint steel pipe be structure as a whole.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of internal-combustion engine outlet and exhaust gear joint steel pipe, be made up of the steel pipe being provided with stiffening rib and the flange plate that is welded in end, it is characterized in that: described stiffening rib is that several axial distribution are on tube wall and with it for the arc being integrally connected structure is rectangular.
Form the outlet of above-mentioned internal-combustion engine also to comprise with the additional technical feature of exhaust gear joint steel pipe:
---described arc rectangular for end face be the rectangular triangle of arc-shaped;
---described arc rectangular for end face be crowded nose elongate configuration;
---the wing hem width degree of described flange plate is greater than the rectangular height of described arc;
---be welded with the second connecting tendon at described flange plate with being connected between steel cylinder.
Internal-combustion engine outlet provided by the utility model and exhaust gear joint steel pipe compared with prior art, have the following advantages; One, due to form the Steel pipe end surface axis of this joint steel pipe tube wall on be distributed with and do stiffening rib for the arc being integrally connected structure is rectangular with it, namely stiffening rib is the inalienable part of steel pipe, substantially increase join strength between the two, namely no matter internal-combustion engine occurs, and trembling of sample both can not be separated, and therefore improves the working life of joint steel pipe; Its two, due to the arc stiffening rib that is structure as a whole with weld between Steel pipe end surface with flange plate, not only increase connection area between the two, turn improve weld strength between the two; Its three, owing to being welded with the second connecting tendon at flange plate with being connected between steel cylinder, the connection lifetime between joint steel pipe and internal-combustion engine can be improved further.

Fig. 2 is the end-face structure schematic diagram of the steel pipe in Fig. 1;
Fig. 3 is the structural representation of the outlet of the utility model internal-combustion engine and exhaust gear joint steel pipe;
Fig. 4 is the end-face structure schematic diagram of the steel pipe in Fig. 3;
Fig. 5 is the end-face structure schematic diagram of the second steel pipe in Fig. 3.
Embodiment
Below in conjunction with accompanying drawing, the outlet of the utility model internal-combustion engine and the structure of exhaust gear joint steel pipe and use principle are described in further detail.
As shown in Figure 3,4, be the outlet of the utility model internal-combustion engine and the structural representation of exhaust gear joint steel pipe.The structure forming this joint steel pipe is made up of with the flange plate 3 being welded in end the steel pipe 2 being provided with stiffening rib 1, wherein stiffening rib be three (size according to caliber sets) axial distribution on tube wall and be the rectangular shape of triangular ridges bar 6 that the end face being integrally connected structure is protruding circular arc 5 shape with it, the rectangular shape of triangular ridges bar 6 of also can be end face be as shown in Figure 5 crowded nose 7 shapes.End face weld by steel pipe is connected to the side of flange plate.
Forming the outlet of above-mentioned internal-combustion engine with the structure of exhaust gear joint steel pipe,
---wing limit 8 width of above-mentioned flange plate is greater than the rectangular height 9(of above-mentioned arc as Fig. 4), what can make that the end face of steel pipe can be complete is welded on the wing limit of flange plate, avoids the formation of leakage;
---in order to improve the weld strength between flange plate and steel pipe further, the outer side surface of flange plate and steel pipe is welded with the second connecting tendon 10.
