Abstract
The utility model discloses a seamless steel pipe for a screw key. The seamless steel pipe is characterized in that the section of a pipe body is of an abnormal structure, the outer wall of the pipe body is of a positive hexagon structure, a transition circular arc is arranged between the adjacent sides, and the inner wall of the pipe body is of a round structure; and the pipe body is formed through drawing, the pipe body material is 45 # steel, and the pipe body is subjected to positive fire heat treatment. The seamless steel pipe for the screw key provided by the utility model has the advantages of low production cost and high intensity.
Description
Technical field
The utility model relates to a kind of seamless steel pipe, relates 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 development and 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 component of machine such as agricultural, mine, engineering, electrician, weaving, military project, seamless steel pipe still is that the application of military industry field is all very extensive at civil area.
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 screw wrench requires to have the intensity height, 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.
The model utility content
Technical problem to be solved in the utility model 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 technological scheme that the utility model adopted is: a kind of screw wrench seamless steel pipe, body cross section are abnormally-structured, and outer wall is the regular hexagon structure, and are provided with transition arc between the 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 beneficial effects of the utility model are: because this screw wrench adopts the structure of circular hole in the outer-hexagonal 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 adopted odd-shaped cross section,, can alleviate structure weight greatly satisfying under the condition such as equal usability; And the moment of inertia and the section modulus of tubing are bigger, and under the condition that is subjected to plane bending and distortion, resistance to flexure and anti-twist ability are big;
Because the body material adopts No. 45 steel, and body makes body intensity height, excellent corrosion resistance through normalizing heat treatment.
Description of drawings
Fig. 1 is a cross section structure schematic representation of the present utility model.
Among Fig. 1: 1. body cross section, 2. outer wall, 3. inwall.
Embodiment
Below in conjunction with accompanying drawing, describe specific embodiments of the present utility model 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 the adjacent both sides, inwall 3 rounded structures.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 the structure of circular hole in the outer-hexagonal 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 adopted odd-shaped cross section,, can alleviate structure weight greatly satisfying under the condition such as equal usability; And the moment of inertia and the section modulus of tubing are bigger, and under the condition that is subjected to plane bending and distortion, resistance to flexure and anti-twist ability are big;
Because the body material adopts No. 45 steel, and body makes body intensity height, excellent corrosion resistance through normalizing heat treatment.
