Abstract
The invention discloses a seamless steel tube for screw spanners. The section of the seamless steel tube is of a special-shaped structure, and the outer wall thereof is of a regular hexagonal structure. Transitional arcs are arranged between the two adjacent edges, and the inner wall of the seamless steel tube is of circular structure. The seamless steel tube made of steel No. 45 is formed by pulling and is subjected to normalizing thermal treatment. The seamless steel tube for screw spanners is low in production cost and high in strength.
Description
Technical field
The present invention relates to a kind of seamless steel pipe, relate in particular to a kind of screw wrench seamless steel pipe.
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 widely used in structural members such as making automobile, train, aircraft, steamer, space gun, 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 seamless 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 seamless steel pipe can not satisfy the specific usage requirement of structure member or mechanical part, for example to require to have intensity high for screw wrench, the conditions such as counter-bending ability is strong, excellent corrosion resistance, lightweight construction also need to possess complicated shape and structure simultaneously, therefore just can not make of common circular section seamless steel pipe.
Summary of the invention
Technical problem to be solved by this invention is: the screw wrench that a kind of cost of production is low, intensity is high seamless steel pipe is provided.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of screw wrench seamless steel pipe, body cross section are abnormally-structured, and outer wall is the regular hexagon structure, and is provided with transition arc between adjacent both sides, the rounded structure of inwall.
Described body is through the drawing moulding.
Described body material is No. 45 steel.
Described body is through normalizing heat treatment.
The invention has the beneficial effects as follows: because this screw wrench adopts outer-hexagonal inner circle pore structure to be convenient to be connected use with other parts with seamless steel pipe, outer-hexagonal has increased the steadiness of joint.
Because this screw wrench is the drawing moulding with seamless steel pipe, need not extra cutting, can save metal, improve stock utilization, and simplified manufacturing process, improved labour productivity;
Owing to having adopted odd-shaped cross section, satisfying under the conditions such as equal usability, can greatly alleviate structure weight; And moment of inertia and the section modulus of tubing are larger, and under the condition that is subjected to plane bending and distortion, resistance to flexure and anti-twist ability are large;
Because the body material adopts No. 45 steel, and body makes body intensity high, excellent corrosion resistance through normalizing heat treatment.
Description of drawings
Fig. 1 is cross section structure schematic diagram of the present invention.
In Fig. 1: 1. body cross section, 2. outer wall, 3. inwall.
Embodiment
Below in conjunction with accompanying drawing, describe specific embodiments of the present invention in detail.
As shown in Figure 1, a kind of screw wrench seamless steel pipe, body cross section 1 is abnormally-structured, outer wall 2 is the regular hexagon structure, and is provided with transition arc between adjacent both sides, the rounded structure of inwall 3.Described body is through the drawing moulding.The body material is No. 45 steel.Described body is through normalizing heat treatment.
Because this screw wrench adopts outer-hexagonal inner circle pore structure to be convenient to be connected use with other parts with seamless steel pipe, outer-hexagonal has increased the steadiness of joint.
Because this screw wrench is the drawing moulding with seamless steel pipe, need not extra cutting, can save metal, improve stock utilization, and simplified manufacturing process, improved labour productivity;
Owing to having adopted odd-shaped cross section, satisfying under the conditions such as equal usability, can greatly alleviate structure weight; And moment of inertia and the section modulus of tubing are larger, and under the condition that is subjected to plane bending and distortion, resistance to flexure and anti-twist ability are large;
Because the body material adopts No. 45 steel, and body makes body intensity high, excellent corrosion resistance through normalizing heat treatment.
