Abstract
The utility model discloses a high-strength sectional bar comprising a middle shaft plate, wherein wing plates are respectively arranged on the two sides of the middle shaft plate; the middle parts of the wing plates are connected with the middle shaft plate and are vertical to the middle shaft plate; and the thickness of each wing plate is gradually reduced from the middle part to the two ends. The sectional bar is molded by drawing. The material of the sectional bar is 40Cr. The sectional bar is subjected to regulation and heat treatment. The utility model provides the high-strength sectional bar with small size and good strength.
Description
Technical field
The utility model relates to a kind of section bar, relates in particular to a kind of high strength section bar.
Background technique
The high strength section bar is used for being subjected in building field and the machinery part of alternate load more, requires section bar itself to have splendid resistance to compression, stretch-proof, torsional resistance.This type of common section bar has H shaped steel and I-steel, and the I-steel cross section is subjected to vertical compression power good, anti-drawing, but sectional dimension is too thin because of wing plate, and can not be antitorque.H shaped steel torsional property is good, but because wing plate thickness is identical, its resistance to compression and stretch-proof ability.In actual the use,, usually need to select for use relatively large number section bar, not only increased user cost, also need take than large space in order to satisfy requirement of strength.
The model utility content
Technical problem to be solved in the utility model is: the high strength that a kind of size is little, intensity is good section bar is provided.
For solving the problems of the technologies described above, the technological scheme that the utility model adopted is: a kind of high strength section bar, comprise middle axillare, and the both sides of middle axillare are respectively equipped with wing plate, the wing plate middle part is in middle axillare is continuous and perpendicular to middle axillare, wing plate thickness progressively reduces from the middle to both ends.
Described section bar is through the drawing moulding.
Described profile material is 40Cr.
Described section bar is through modulation heat treatment.
The beneficial effects of the utility model are: because section bar comprises middle axillare and wing plates on two sides, wing plate thickness progressively reduces from the middle to both ends, and not only compression resistance is superior to make this section bar, and its torsional property is also very outstanding.The part dimension of producing than other modes in identical use occasion is littler, and quality is lighter, and performance is more excellent.
Because this section bar is the drawing moulding, has simplified manufacturing process, has improved labour productivity;
Owing to adopt the 40Cr material, and, make section bar intensity height, excellent corrosion resistance through overmodulation heat treatment.
Description of drawings
Fig. 1 is a cross section structure schematic representation of the present utility model.
Among Fig. 1: 1. axillare in, 2. wing plate.
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 high strength section bar, axillare 1 in comprising, the both sides of middle axillare 1 are respectively equipped with wing plate 2, and wing plate 2 middle parts link to each other and perpendicular to middle axillare 1, wing plate 2 thickness progressively reduce from the middle to both ends in middle axillare 1.Described section bar is through the drawing moulding.Described profile material be 40Cr and through the modulation heat treatment.
Because axillare 1 and wing plates on two sides 2 during section bar comprises, wing plate 2 thickness progressively reduce from the middle to both ends, and not only compression resistance is superior to make this section bar, and its torsional property is also very outstanding.The part dimension of producing than other modes in identical use occasion is littler, and quality is lighter, and performance is more excellent.
Because this section bar is the drawing moulding, has simplified manufacturing process, has improved labour productivity;
Owing to adopt the 40Cr material, and, make section bar intensity height, excellent corrosion resistance through overmodulation heat treatment.
