Description
[technical field]
The utility model is related to part of automobile engine technical field, and specifically a kind of High-strength light-weight is started
Machine blast pipe hot junction support.
[background technology]
With making rapid progress for auto industry and continuing to develop for modern manufacturing industry, with new design concept and manufacturing technology
Time-tested traditional parts are improved with improvement, traditional hot junction support stationary engine blast pipe has done two and added
Strengthening tendons, is also some point contacts in fact at contact blast pipe on casting surface, reinforcement due to being, actual not reach two
Reinforcement support effect can preferably be envisioned；The groove of a closing is formd in the centre of two reinforcements on the contrary, when a large amount of
Substantial amounts of heat is accumulated when the gas of high temperature hyperpyrexia passes through blast pipe, in groove not distributing not go out, but no water route is given and dropped
Temperature, engine work is just gradually cooled down after stopping, and this is closed in the course of time relative to constantly being annealed to rack groove part
Groove part becomes fragile, and can influence the support strength to blast pipe；Meanwhile, the reinforcement of groove part is higher by mounting plane and exceeded
40mm, it is also inconvenient in installation locking, influence installation effectiveness.
[utility model content]
The purpose of this utility model seeks to solve above-mentioned deficiency and provide a kind of High-strength light-weight engine exhaust
Pipe hot junction support, not only increases support strength, alleviates weight, also improve thermal diffusivity and installation effectiveness, while structure is new
Grain husk, it is reasonable in design.
A kind of High-strength light-weight exhaust pipe of engine hot junction support, including hot junction support sheet are designed to achieve the above object
Body, the hot junction rack body includes the connecting plate 1 being connected with the exhaust pipe of engine and for supporting the exhaust pipe of engine
Reinforcement 5, offer Pipe installing hole 2 on the connecting plate 1, the connecting plate 1 is fixedly connected with hair by Pipe installing hole 2
Motivation blast pipe, the left and right sides of connecting plate 1 is respectively arranged with left side flap 3, right side flap 4, the left side flap 3, connecting plate 1,
Right side flap 4 constitutes the C-shaped arcuate structure in cross section, and the reinforcement 5 is to extend to the inner side of right side flap 4 from the inner side of left side flap 3
Arcuate structure, the left and right ends of reinforcement 5 are respectively fixedly connected with left side flap 3, right side flap 4.
The edge of the reinforcement 5 has additional assistant reinforcement muscle 5, and described one end of assistant reinforcement muscle 5 is welded on reinforcement 5
On, the other end of assistant reinforcement muscle 5 is welded on connecting plate 1.
Fastening bolt holes 6 are offered in the left side flap 3, right side flap 4.
The connecting plate 1, left side flap 3, right side flap 4, reinforcement 5 are integral type structure.
The Pipe installing hole 2 is provided with least two, and the Pipe installing hole 2 is welded as one with the exhaust pipe of engine
Body.
Compared with the existing technology, structure is novel, reasonable in design for the utility model, is passing through a large amount of theory analysis data and platform
After the data of frame experiment, two reinforcements in traditional structure are changed to a reinforcement, so as to renovate the knot of hot junction support
Structure is designed, and appropriate thickening is carried out to this reinforcement, and assistant reinforcement muscle several small can be also designed on reinforcement side,
So as to which on the benchmark for meeting existing support strength requirement, support strength further increases 20%；Also, it is changed to a reinforcement
After muscle, heat dispersion improves more than 45%, it is to avoid influence of the continuous annealing to support intensity, meanwhile, reinforcement is entered
After row optimization, product weight reduces 35%, installs and is also no longer perplexed by the high inconvenient installation of reinforcement, that is, enhances support strong
Degree alleviates weight and also improves thermal diffusivity and installation effectiveness, is worthy of popularization.
[brief description of the drawings]
Fig. 1 is structural representation of the present utility model；
Fig. 2 is existing structural representation；
In figure：1st, connecting plate 2, Pipe installing hole 3, left side flap 4, right side flap 5, reinforcement 6, fastening bolt holes 7,
Reinforcement 1, reinforcement two.
[embodiment]
Further explained below is made to the utility model below in conjunction with the accompanying drawings：
As shown in Figure 1, the utility model includes：Hot junction rack body, hot junction rack body includes and engine exhaust
Pipe installing hole is offered on the connecting plate 1 that pipe is connected and the reinforcement 5 for supporting the exhaust pipe of engine, connecting plate 1
2, connecting plate 1 is fixedly connected with the exhaust pipe of engine by Pipe installing hole 2, and the Pipe installing hole 2 is provided with least two, pipeline
Mounting hole 2 is welded as a whole with the exhaust pipe of engine, and the left and right sides of connecting plate 1 is respectively arranged with left side flap 3, right side flap 4, left side
The wing 3, connecting plate 1, right side flap 4 constitute the C-shaped arcuate structure in cross section, and reinforcement 5 is to extend to right side from the inner side of left side flap 3
The arcuate structure of the inner side of the wing 4, the left and right ends of reinforcement 5 are respectively fixedly connected with left side flap 3, right side flap 4, can also be in reinforcement 5
Edge has additional assistant reinforcement muscle 5, and the one end of assistant reinforcement muscle 5 is welded on reinforcement 5, and the other end of assistant reinforcement muscle 5 is welded on
On connecting plate 1；Fastening bolt holes 6, connecting plate 1, left side flap 3, right side flap 4, reinforcement are offered in the left side flap 3, right side flap 4
Muscle 5 is integral type structure.
The utility model changes product structure, is fully meeting function after multiple sunykatuib analysis and bench test
On the premise of, support blast pipe junction structure is modified so that structural strength increase by 20% at support blast pipe, entirely
The weight saving 35% of support, the performance enhancement 45% radiated during work, is more easily installed when mounted, greatly improves installation
Efficiency.
As shown in Figure 2, it is existing hot junction support, the support of itself and the exhaust pipe of engine has used two reinforcements,
Its drawback is that the sealing space formed between two reinforcements constantly assembles the heat that the waste gas of high temperature hyperpyrexia is conducted, and
And can not shed in time, prolonged reciprocal heat can not shed and engine cool, can cause the insufficient strength of support.This reality
Designed with new by changing, reach new structure as shown in Figure 1, two reinforcements are changed to a reinforcement by it, and
Overall structure is renovated, and reinforcement is suitably thickeied by mechanical analysis and added again on this reinforcement side
Upper small assistant reinforcement muscle, so as to reach it is expected want to meet by force intensity.
The utility model is simultaneously not limited to the embodiments described above limitation, other any real without departing from spirit of the present utility model
Matter and the change made under principle, modification, replacement, combine, simplify, should be equivalent substitute mode, be included in this practicality
Within new protection domain.
