Abstract

The utility model relates to a deformed seamless steel tube, in particular to a polygonal seamless tube for carrying a vehicle window. The polygonal seamless tube is characterized in that a cavity (1) of the polygonal seamless tube is in a polygonal structure composed of a rectangle (2) and a corner-unfilled sector (3),a crossing position of a long bottom edge and a short left edge of the rectangle (2) is punched inwardly to form a notch (2.1), a long top edge of the rectangle (2) and a bottom straight edge of the sector (3) are the same in length and fitted with each other.

Description

Vehicle window carrying polygonal weldless tube
Technical field
The utility model relates to a kind of special-shaped seamless steel pipe, relates in particular to a kind of vehicle window carrying polygonal weldless tube.
Background technique
At present, seamless steel pipe is widely used in manufacturing structure spare and mechanical parts, as steel scaffold of using in oil drill rocker, truck drive shaft and the construction etc.Make ring-shaped work pieces with seamless steel pipe, can improve stock utilization, simplify manufacturing process, economical with materials is also saved man-hour.In these seamless steel pipes, circular pipe 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 seamless steel pipes are pipes.
Yet pipe is because shape restriction makes it can't be used for some particular surroundingss, because the moment of inertia of pipe and section modulus are less, its bending resistance and anti-twisting property are relatively poor, and intensity is low, and it is more to make the steel that pipe consumes, and makes that its cost is higher.Above a variety of causes has limited the Applicable scope of pipe, does not therefore adopt pipe to be used as structural member or machine part under some particular surroundingss.
For example the weldless tube of using in the Bus window needs the higher intensity of having of this weldless tube and certain bending resistance, anti-twisting property, and common like this pipe just can not reach requirement.
Summary of the invention
In order to overcome above-mentioned deficiency, the utility model provides a kind of intensity higher, and bending resistance and the stronger vehicle window carrying polygonal weldless tube of anti-twisting property.
The purpose of this utility model is achieved in that
The carrying of the utility model vehicle window is a polygon structure with the cavity of polygonal weldless tube, this polygon structure is by rectangle and unfilled corner is fan-shaped forms, long limit, the bottom of described rectangle and the inside punching press in minor face intersection, left side form breach, the top longitudinal edge of described rectangle and the fan-shaped identical and mutual applying of bottom length of straight flange.
Compared with prior art, the beneficial effects of the utility model are:
This vehicle window carrying changes normally used pipe into the polygonal weldless tube with the polygonal weldless tube, so not only makes the vehicle window carrying higher with polygonal weldless tube intensity, and resistance to compression and anti-twisting property are stronger.
Description of drawings
Fig. 1 is the cross-sectional view of the utility model vehicle window carrying with the polygonal weldless tube.
Wherein: cavity 1, rectangle 2, breach 2.1, fan-shaped 3.
Embodiment
Referring to Fig. 1, the utility model relates to a kind of vehicle window carrying polygonal weldless tube, this vehicle window carrying is a polygon structure with the cavity 1 of polygonal weldless tube, this polygon structure is made up of rectangle 2 and unfilled corner fan-shaped 3, long limit, the bottom of described rectangle 2 and the inside punching press in minor face intersection, left side form breach 2.1, the top longitudinal edge of described rectangle 2 and fan-shaped 3 the identical and mutual applying of bottom length of straight flange.

Claims (1)

1. a vehicle window carries and uses the polygonal weldless tube, it is characterized in that: described vehicle window carrying is a polygon structure with the cavity (1) of polygonal weldless tube, this polygon structure is made up of rectangle (2) and unfilled corner fan-shaped (3), long limit, the bottom of described rectangle (2) and the inside punching press in minor face intersection, left side form breach (2.1), and the mutual applying identical with the bottom length of straight flange of fan-shaped (3) of the top longitudinal edge of described rectangle (2).
