Abstract
The utility model discloses a special pipe for an internal combustion engine, which comprises a first arm part, a second arm part and a connecting part connecting the first arm part with the second arm part, wherein a round through hole is arranged in the middle of the connecting part, and the connecting part is vertical to the first arm part and the second arm part respectively. The special pipe not only has high strength and long fatigue life, but also resists high temperature and high pressure.
Description
Technical field
The utility model relates to a kind of steel pipe, is specifically related to a kind of internal-combustion engine and uses steel tubing in different shapes.
Background technique
Seamless steel tube production is one of national pillar industry, and along with development and national economy, the demand of seamless steel pipe is the trend of cumulative year after year.Seamless steel pipe is used to make structural members such as automobile, train, aircraft, steamer, space gun; And components of machine such as agricultural, mine, engineering, electrician, weaving, military project, seamless steel pipe civil area still be military industry field application all very extensively.Because the circular section steel pipe is stressed more even when bearing inside or outer radial pressure; So obtain a large amount of uses; But in many cases; The circular section steel pipe can not satisfy the specific usage requirement of structure member or mechanical part, therefore just needs extraordinary steel tubes come manufacturing structure parts or mechanical part, improves stock utilization and simplifies purposes such as production technology, shortening manufacture cycle to reach.
Steel tubing in different shapes is compared with pipe, and the sectional shape of pipe is limited, has certain narrow limitation; Can't be used for some specified conditions and environment, and steel tubing in different shapes has more the Economic Section advantage, adapt to the particularity of service condition; Can practice thrift metal; Improve stock utilization, simplify manufacturing process, raise labour productivity; Steel tubing in different shapes is compared with pipe, and steel tubing in different shapes all is superior to pipe in the overall appearance moulding and the design concept of product; Steel tubing in different shapes is compared with pipe, is satisfying under the conditions such as equal usability, and steel tubing in different shapes can alleviate structure weight greatly; The moment of inertia and the section modulus of pipe are less, and under the condition that receives plane bending and distortion, it is big to be not so good as steel tubes resistance to flexure and anti-twist ability; The pipe and the steel tubing in different shapes of the same length of side and diameter, steel tubing in different shapes bearing capacity and shock resistance are better; More than multiple reason limited the service condition and the scope of pipe; Under some particular surroundingss and condition; So adopt steel tubing in different shapes to make structure member or mechanical part, for example: internal-combustion engine has high temperature resistant, high pressure resistant to part requirement, also need satisfy service conditions such as high tenacity and long-fatigue life simultaneously; And the component shape and structure is tending towards complicated, therefore just can not adopt steel tubing in different shapes to make with pipe.
The model utility content
The utility model technical problem to be solved is: provide that a kind of intensity is high, fatigue life long, high temperature resistant, high voltage bearing internal-combustion engine use steel tubing in different shapes.
For solving the problems of the technologies described above; The technological scheme that the utility model adopts is: a kind of internal-combustion engine is used steel tubing in different shapes; This steel tubing in different shapes comprises: first arm, second arm and connect the joint of first, second arm; The centre of said joint is provided with manhole, and said joint is perpendicular with first, second arm respectively.
The beneficial effect of the utility model is: through in internal-combustion engine, using above-mentioned steel tubing in different shapes, not only intensity is high, fatigue life is long but also high temperature resistant, high pressure resistant.
Description of drawings
Fig. 1 is the schematic cross-section of internal-combustion engine with steel tubing in different shapes.
Among Fig. 1: 100, internal-combustion engine is used steel tubing in different shapes, 1, first arm, 2, second arm, 3, joint, 30 manholes.
Embodiment
See also Fig. 1; A kind of internal-combustion engine is with steel tubing in different shapes 100; It comprises: first arm 1, second arm 2 and connect the joint 3 of first, second arm, and the centre of said joint 3 is provided with manhole 30, and said joint 3 is perpendicular with first, second arm 1,2 respectively.Said joint 3 and first, second arm 1, there is not arc transition between 2.Said steel tubing in different shapes 100 is I shape, and said steel tubing in different shapes 100 is and is symmetrical set.Said steel tubing in different shapes 100 is processed by the 40Cr steel, and process carbonitriding heat treatment, thereby can increase the surface hardness of steel tubing in different shapes 100.
Not only intensity is high, fatigue life is long but also high temperature resistant, high pressure resistant with steel tubing in different shapes 100 for internal-combustion engine in the utility model.
