Abstract
The utility model relates to a special-shaped seamless steel tube, in particular to a seamless tube for a car door upright column. The seamless tube is characterized in that the section of a tube body (1) of the seamless tube appears in a P-shaped structure, an arc segment (1.1) of the P-shaped structure comprises an upper arc edge (1.1.1) and a lower arc edge (1.1.2), and the upper arc edge (1.1.1) and the lower arc edge (1.1.2) are both stamped inwards so as to form a groove (2). The upper arc edge (1.1.1) and the lower arc edge (1.1.2) are both stamped inwards by the seamless tube for the car door upright column on the basis of the P-shaped tube body, so that two grooves are formed on the tube body (1), therefore, the car door upright column is light, has high strength and strong capacity of resisting compression and twist.
Description
Technical field
The utility model relates to a kind of special-shaped seamless steel pipe, relates in particular to a kind of car door column and uses seamless tube.
Background technology
At present, solid drawn pipe is widely used in manufacturing structure spare and mechanical component, like steel scaffold of using in oil drill rocker, propeller-shaft, bicycle rack and the building operation etc.Make ring-shaped work pieces with solid drawn pipe, can improve stock utilization, simplify Fabrication procedure, economical with materials is also saved man-hour.In these solid drawn pipes, round tube can be carried more fluid.In addition, ring cross-section is when bearing inside or outer radial pressure, and is stressed more even, and therefore most solid drawn pipes are pipes.
Yet pipe makes it can't be used for some particular surroundingss because shape limits, because the moment of inertia of pipe and modulus of section are less, its bending resistance and anti-twisting property are relatively poor, and intensity is low, and it is more to process the steel that pipe consumes, and makes that its cost is higher.Above a variety of causes has limited the Applicable scope of pipe, therefore under some particular surroundingss, does not adopt pipe to be used as framing member or machine part.
For example the car door column of passenger vehicle is used seamless tube, because the frequent switch of car door needs the higher intensity of having of seamless tube and certain bending resistance, anti-twisting property during use, common like this pipe just can not reach requirement.
Summary of the invention
In order to overcome above-mentioned deficiency, the utility model provides that a kind of weight is light, intensity is higher, and bending resistance and the stronger car door column of anti-twisting property are used seamless tube.
The purpose of the utility model is achieved in that
The utility model car door column is " P " font structure with the body cross section of seamless tube, and the arc section that is somebody's turn to do " P " font structure comprises circular arc limit and following circular arc limit, said circular arc limit and all inside punching press formation in the following circular arc limit groove gone up.
Compared with prior art, the beneficial effect of the utility model is:
This car door column will be gone up circular arc limit and the inside punching press in following circular arc limit with seamless tube on the basis of " P " font body; Make and form two grooves on the body 1; Make that so not only the weight of car door column is lighter, make that also its intensity is higher, resistance to compression and anti-twisting property are stronger.
Description of drawings
Fig. 1 is the cross-sectional view of the utility model car door column with seamless tube.
The cross section was the scheme drawing of " P " font structure when Fig. 2 made for Fig. 1 middle tube body 1.
Wherein: body 1, arc section 1.1, last circular arc limit 1.1.1, following circular arc limit 1.1.2, groove 2.
The specific embodiment
Referring to Fig. 1 and Fig. 2; The utility model relates to a kind of car door column and uses seamless tube; This car door column is " P " font structure with the cross section of the body 1 of seamless tube; Arc section 1.1 that should " P " font structure comprises circular arc limit 1.1 and following circular arc limit 1.1.2, saidly goes up circular arc limit 1.1.1 and all inside punching press of following circular arc limit 1.1.2, makes two grooves 2 of formation on the body 1.
Claims (1)
1. a car door column is used seamless tube; It is characterized in that: said car door column is " P " font structure with the cross section of the body (1) of seamless tube; The arc section (1.1) that is somebody's turn to do " P " font structure comprises circular arc limit (1.1) and following circular arc limit (1.1.2), the said all inside punching press formation in circular arc limit (1.1.1) and following circular arc limit (1.1.2) groove (2) of going up.
