Abstract
The utility model discloses a round-outside square-inside tube used for a socket spanner. The outer wall of the round-outside square-inside tube used for the socket spanner is arranged to be circular, and the inner wall of the round-outside square-inside tube used for the socket spanner is arranged to be rectangular. The round-outside square-inside tube used for the socket spanner has the advantages of being high in strength, high in rigidity, good in flexibility, long in service life, strong in fatigue durability, strong in non-deformability, good in temperature difference resistance, and the like.
Description
Technical field
The utility model relates to a kind of steel tubing in different shapes, is specifically related to the round outside but spuare inside pipe of a kind of socket wrench.
Background technique
Seamless steel tube production is one of national pillar industry, and along with the development of national economy, the demand of seamless steel pipe is the trend of cumulative year after year.Seamless steel pipe is for the manufacture of structural members such as automobile, train, aircraft, steamer, space guns, and the component of machine such as agricultural, mine, engineering, electrician, weaving, military project, seamless steel pipe is at civil area or the application of military industry field is all very extensive.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 need extraordinary steel tubes come manufacturing structure parts or mechanical part, improve stock utilization and simplify the purposes such as production technology, shortening manufacture cycle to reach.
Steel tubing in different shapes is compared with pipe, 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 save 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 better than pipe in 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; Moment of inertia and the section modulus of pipe are less, under the condition that is subjected to plane bending and distortion, are not so good as steel tubes resistance to flexure and anti-twist ability large; 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; Above many reasons has limited service condition and the scope of pipe, under some particular surroundingss and condition, make structure member or mechanical part so adopt steel tubing in different shapes, such as: should have the service conditions such as intensity is high, hardness is high, good toughness, long service life, fatigue resistance is strong, non-deformability is strong, temperature difference resistance is good to socket wrench with pipe, therefore just can not adopt steel tubing in different shapes to make with pipe.
The model utility content
A technical problem to be solved in the utility model is: provide that a kind of intensity is high, hardness is high, the round outside but spuare inside pipe of the socket wrench of good toughness.
For solving the problems of the technologies described above, the utility model adopts following technological scheme: the round outside but spuare inside pipe of a kind of socket wrench, described socket wrench be with the rounded setting of the outer wall of round outside but spuare inside pipe, and described socket wrench is with the rectangular setting of the inwall of round outside but spuare inside pipe.
As a kind of preferred technological scheme, described socket wrench comprises first wall section, the second wall section, the 3rd wall section and wall section with the inwall of round outside but spuare inside pipe, be provided with the First Transition circular arc between described first wall section and the second wall section, be provided with the second transition arc between described the second wall section and the 3rd wall section, be provided with the 3rd transition arc between described the 3rd wall section and the wall section, be provided with the 4th transition arc between described wall section and the first wall section.
As a kind of preferred technological scheme, described first wall section, the second wall section, the 3rd wall section and wall section are around forming a square.
As a kind of preferred technological scheme, described socket wrench is made by No. 45 steel with round outside but spuare inside pipe.
The beneficial effects of the utility model: the socket wrench in the utility model has the advantages such as intensity is high, hardness is high, good toughness, long service life, fatigue resistance is strong, non-deformability is strong, temperature difference resistance is good with round outside but spuare inside pipe.
Description of drawings
Fig. 1 is socket wrench with the structural representation of round outside but spuare inside pipe.
Among Fig. 1: 1, outer wall, 2, inwall, 20, first wall section, the 21, second wall section, the 22, the 3rd wall section, 23, wall section, 24, the First Transition circular arc, the 25, second transition arc, the 26, the 3rd transition arc, the 27, the 4th transition arc.
Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein only is used for description and interpretation the utility model, and be not used in restriction the utility model.
See also Fig. 1, the round outside but spuare inside pipe of a kind of socket wrench, described socket wrench be with the outer wall 1 rounded setting of round outside but spuare inside pipe, and described socket wrench is with the inwall 2 rectangular settings of round outside but spuare inside pipe.Described socket wrench comprises first wall section 20, the second wall section 21, the 3rd wall section 22 and wall section 23 with the inwall 2 of round outside but spuare inside pipe, be provided with First Transition circular arc 24 between described first wall section 20 and the second wall section 21, be provided with the second transition arc 25 between described the second wall section 21 and the 3rd wall section 22, be provided with the 3rd transition arc 26 between described the 3rd wall section 22 and the wall section 23, be provided with the 4th transition arc 27 between described wall section 23 and the first wall section 20.Described first wall section 20, the second wall section 21, the 3rd wall section 22 and wall section 23 are around forming a square.Described socket wrench is made by No. 45 steel with round outside but spuare inside pipe, and through Carburization Treatment.
Socket wrench in the utility model has the advantages such as intensity is high, hardness is high, good toughness, long service life, fatigue resistance is strong, non-deformability is strong, temperature difference resistance is good with round outside but spuare inside pipe.
It should be noted that at last: the above only is preferred embodiment of the present utility model, be not limited to the utility model, although with reference to previous embodiment the utility model is had been described in detail, for a person skilled in the art, it still can be made amendment to the technological scheme that aforementioned each embodiment puts down in writing, and perhaps part technical characteristics wherein is equal to replacement.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
