Abstract
The invention discloses a round-outside and rectangular-inside tube used for a socket spanner. The round-outside and rectangular-inside tube used for the socket spanner adopts the section with a special-shaped structure. The outer wall of the round-outside and rectangular-inside tube used for the socket spanner is round, and the inner wall of the round-outside and rectangular-inside tube used for the socket spanner is rectangular. The round-outside and rectangular-inside tube used for the socket spanner has the advantages of high strength, high hardness, good toughness, long service life, strong fatigue resistance, strong deformation resistance, excellent temperature difference resistance, and the like.
Description
Technical field
The present invention relates to a kind of steel tubing in different shapes, be specifically related to a kind of socket wrench and use round outside but spuare inside pipe.
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; Make structure member or mechanical part so adopt steel tubing in different shapes; For example: to socket wrench with pipe should have intensity height, hardness height, good toughness, long service life, service condition such as fatigue resistance is strong, non-deformability is strong, temperature difference resistance is good, so just can not adopt steel tubing in different shapes to make with pipe.
Summary of the invention
A technical problem to be solved by this invention is: provide a kind of intensity height, hardness socket wrench high, good toughness to use round outside but spuare inside pipe.
For solving the problems of the technologies described above; The present invention adopts following technological scheme: a kind of socket wrench is used round outside but spuare inside pipe; Said socket wrench is abnormally-structured with the cross section of round outside but spuare inside pipe; Said socket wrench is with the rounded setting of the outer wall of round outside but spuare inside pipe, and said socket wrench is with the rectangular setting of the inwall of round outside but spuare inside pipe.
As a kind of optimized technical scheme; Said socket wrench comprises first wall portion, the second wall portion, the 3rd wall portion and wall portion with the inwall of round outside but spuare inside pipe; Be provided with first transition arc between the said first wall portion and the second wall portion; Be provided with second transition arc between said second wall portion and the 3rd wall portion, be provided with the 3rd transition arc between said the 3rd wall portion and the wall portion, be provided with the 4th transition arc between said wall portion and the first wall portion.
As a kind of optimized technical scheme, said first wall portion, the second wall portion, the 3rd wall portion and wall portion are around forming a square.
As a kind of optimized technical scheme, said socket wrench is processed by No. 45 steel with round outside but spuare inside pipe.
Beneficial effect of the present invention: the socket wrench among the present invention with round outside but spuare inside pipe have intensity height, hardness height, good toughness, long service life, advantage such as fatigue resistance is strong, non-deformability is strong, temperature difference resistance is good.
