Abstract
The invention discloses a seamless steel tube for bolts. The steel tube is of a special-shaped structure and comprises a steel tube body and a side wing. The side wing is arranged on one side of the steel tube body. The steel tube body comprises a rectangular base and a semicircular top, the middle of the steel tube body is provided with a circular through hole, and the bottom surface of the side wing is flush with the bottom surface of the base. The steel tube body is formed by drawing and made of stainless steel. The seamless steel tube for bolts is low in production cost and good in wear resistance.
Description
Technical field
The present invention relates to a kind of seamless steel pipe, relate in particular to a kind of latch 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 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 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 wear resistance high for latch, the conditions such as non-deformability is high, excellent corrosion resistance 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 latch that a kind of cost of production is low, wear resistance is good 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 latch steel tubes, body is polymorphic structure, body comprises body and is arranged on the flank of body one side, body comprises rectangular base and semi-circular top, the body middle part is provided with manhole, and the bottom surface of flank flushes with base end face.
Described body is through the drawing moulding.
Described body material is stainless steel.
The invention has the beneficial effects as follows: because this latch 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 stainless steel, the body wear resistance is high, excellent corrosion resistance, long service life, beautiful shape.
Description of drawings
Fig. 1 is cross section structure schematic diagram of the present invention.
In Fig. 1: 1. body, 2. flank, 3. base, 4. top, 5. manhole.
Embodiment
Below in conjunction with accompanying drawing, describe specific embodiments of the present invention in detail.
As shown in Figure 1, a kind of latch steel tubes, body are polymorphic structure, body comprises body 1 and is arranged on the flank 2 of body 1 one sides, body 1 comprises rectangular base 3 and semi-circular top 4, and body 1 middle part is provided with manhole 5, and the bottom surface of flank 2 flushes with base 3 bottom surfaces.Described body is stainless steel through drawing moulding and material.
Because this latch 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 stainless steel, the body wear resistance is high, excellent corrosion resistance, long service life, beautiful shape.
