Abstract
The utility model relates to a P-shaped tube for a passenger car door upright post, the section of the P-shaped tube body is of P-shaped structure which comprises straight edge segments (1-1) and circular arc segments (1-2), two adjacent straight edge segments (1-1) are connected by circular arc segments (1-2), the surface of the tube body is provided with an anti-rust lacquer layer (2), the material of the P-shaped tube is Q345B. The P-shaped tube for the passenger car door upright post has advantages of high intensity, light weight, and good vibration and rust resistance effects.
Description
(1) technical field
The utility model relates to a kind of special-shaped seamless steel pipe, especially relates to a kind of passenger door column with " P " shape pipe, belongs to the metallic material technical field.
(2) 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, bicycle frame and the construction etc.Make ring-shaped work pieces with seamless steel pipe, can improve stock utilization, simplify manufacturing process, economical with materials and machining period as rolling bearing lasso, jack cover etc., are extensively made with seamless steel pipe at present.Seamless steel pipe still is various conventional weapon indispensable material, and gun barrel, gun barrel etc. is all wanted steel pipe manufacturing.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 also has certain narrow limitation:
The shape restriction of pipe 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;
The weight of pipe itself is bigger, and is bigger to the pressure of its supporting part;
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 car door column need consider that self intensity of car door column wants high, and it is light that weight is wanted, and want certain shockproof and antirust ability, so just can not use pipe to make.
(3) summary of the invention
In order to overcome above-mentioned deficiency, the utility model provides a kind of passenger door column to use " P " the shape pipe, this passenger door column intensity height of " P " shape pipe, weight is lighter, and shockproof better with rust-proof effect.
The purpose of this utility model is achieved in that
A kind of passenger door column is managed with " P " shape, the section that is somebody's turn to do the body of " P " shape pipe is " P " shape structure, should " P " shape structure include straight section and arc section, connect by arc section between adjacent two described straight sections, described body surface is covered with rust preventive coating, and the material of described " P " shape pipe is Q345B.
The beneficial effect that the utlity model has is: this passenger door column intensity height of " P " shape pipe, weight is lighter, and can play shockproof and antirust effect well.
(4) description of drawings
Fig. 1 is the cross-sectional configuration schematic representation of the utility model passenger door column with " P " shape pipe.
Wherein: body 1, straight section 1-1, arc section 1-2, rust preventive coating 2.
(5) embodiment
As Fig. 1, the utility model relates to a kind of passenger door column and manages with " P " shape, the section that is somebody's turn to do the body 1 of " P " shape pipe is " P " shape structure, should " P " shape structure include straight section 1-1 and arc section 1-2, connect by arc section 1-2 between adjacent two described straight section 1-1, described body 1 surface is covered with rust preventive coating 2, and the material of described " P " shape pipe is Q345B.
Claims (1)
1. a passenger door column is managed with " P " shape, it is characterized in that: the section that is somebody's turn to do the body (1) of " P " shape pipe is " P " shape structure, should " P " shape structure include straight section (1-1) and arc section (1-2), connect by arc section (1-2) between adjacent two described straight sections (1-1), described body (1) surface is covered with rust preventive coating (2), and the material of described " P " shape pipe is Q345B.
