Abstract
The utility model discloses a kind of overhead guard profile structure, comprise four faces, namely plane, lower plane, side plane and side cambered surface is gone up, upper plane is parallel with lower plane, side plane be positioned at plane and lower plane side and perpendicular to upper plane and lower plane, side cambered surface is positioned at the opposite side of plane and lower plane, and four tubing become in face week, tubing cross section is closed-loop.It is abnormally-structured that the utility model provides, and section bar sectional dimension is increased, and when bending, bending angle R is relatively little, greatly can reduce side plane and special-shaped side cambered surface in Forging Process and produce distortion and wrinkle at bending part, section bar deflection after bending, intensity is higher, and the safety of overhead guard is also higher.Meanwhile, profile is simple, attractive in appearance, easily processes.
Description
Technical field
The utility model relates to a kind of novel overhead guard profile structure.
Background technology
Fork truck is one of carrying vehicle of commonly using of present people, be that member pallet cargo carries out loading and unloading, stacking and short range transport, weight transport operation various wheeled carrying vehicle.Be widely used in harbour, station, airport, goods yard, factory floor, warehouse, Transfer center and DISTRIBUTION CENTRE etc., and can enter carry out pallet cargo in cabin, compartment and freight container handling, transport operation, be requisite equipment in pallet traffic, Container Transport.
In order to ensure the safety of truck driver, overhead guard can be installed above driver's seat.Overhead guard is made up of section bar bending.On market, overhead guard section bar is mostly the tubing of rounded, the square or butterfly in cross section, and profile is simple, and sectional dimension is little, and when bending, bending angle R is large, and after bending, section bar deflection is bigger than normal, and intensity is lower, directly affects safety.
Utility model content
The purpose of this utility model is to provide a kind of overhead guard profile structure, and after its bending, section bar deflection is little, and intensity is high.
In order to reach above-mentioned purpose, solution of the present utility model is:
A kind of overhead guard profile structure, comprise four faces, namely plane, lower plane, side plane and side cambered surface is gone up, upper plane is parallel with lower plane, side plane be positioned at plane and lower plane side and perpendicular to upper plane and lower plane, side cambered surface is positioned at the opposite side of plane and lower plane, and four faces surround tubulose section bar, and tubulose section bar cross section is closed-loop.
The width of described upper plane is wider than lower plane.
Knuckle is formed between the adjacent surface in described four faces.
The width of described upper plane is 27 millimeters, and the width of lower plane is 40 millimeters, and the width of side plane is 120 millimeters, and the radius of curvature of side cambered surface is 460 millimeters, and between the adjacent surface in four faces, the radius of knuckle is 5 millimeters, and the thickness in four faces is 3 millimeters.
The width of described upper plane is 27 millimeters, and the width of lower plane is 40 millimeters, and the width of side plane is 65 millimeters, and the radius of curvature of side cambered surface is 140 millimeters, and between the adjacent surface in four faces, the radius of knuckle is 8 millimeters, and the thickness in four faces is 3 millimeters.
After adopting such scheme, it is abnormally-structured that the utility model provides, section bar sectional dimension is increased, when bending, bending angle R is relatively little, greatly can reduce side plane and special-shaped side cambered surface in Forging Process and produce distortion and wrinkle at bending part, section bar deflection after bending, intensity is higher, and the safety of overhead guard is also higher.Meanwhile, profile is simple, attractive in appearance, easily processes.

Label declaration
Section bar 10, upper plane 1, lower plane 2, side plane 3, side cambered surface 4.
Detailed description of the invention
As shown in figures 1 to 6, the utility model discloses a kind of overhead guard section bar 10 structure, comprises four faces, namely goes up plane 1, lower plane 2, side plane 3 and side cambered surface 4.Upper plane 1 is parallel with lower plane 2, and side plane 3 is positioned at the inner side of plane 1 and lower plane 2, and side plane 3 is perpendicular to upper plane 1 and lower plane 2, and side cambered surface 4 is positioned at the outside of plane 1 and lower plane 2.Four faces surround tubulose section bar, and tubulose section bar cross section is closed-loop.Wherein, optimal design is that the width of upper plane 1 is wider than lower plane 2.Knuckle β is formed between the adjacent surface in four faces.
As shown in Figure 1 to Figure 3, it is preferred embodiment one of the present utility model, the width of upper plane 1 is 27 millimeters, the width of lower plane 2 is 40 millimeters, the width of side plane 3 is 120 millimeters, and the radius of curvature R 1 of side cambered surface 4 is 460 millimeters, makes section bar good looking appearance, between the adjacent surface in four faces, the radius R 2 of knuckle β is 5 millimeters, and the thickness d in four faces is 3 millimeters.In addition, when bending overhead guard, accurately controlling bending angle R in design, also can reduce distortion and wrinkle.According in machine design specification, as theory calculate R > 2D (D is the width of side plane 3), the surface at bending angle R place can not produce distortion and fold.Data when D is actual design, can calculate R according to D.In the present embodiment, D gets 120mm, and therefore R > 240mm meets demand.R value is too large, and profile is attractive in appearance not, and it is 300mm that this embodiment gets R, not only attractive in appearance but also easily process, and is not easy distortion.On bending technique, also by adjusting process parameter and Bending Mould, few distortion and wrinkle after making the heavy in section pipe bending of strip shape.
As shown in Figures 4 to 6, it is preferred embodiment two of the present utility model, the width of upper plane 1 is 27 millimeters, the width of lower plane 2 is 40 millimeters, the width of side plane 3 is 65 millimeters, the radius of curvature R 1 of side cambered surface 4 is 140 millimeters, and between the adjacent surface in four faces, the radius R 2 of round-corner transition β is 8 millimeters, and the thickness d in four faces is 3 millimeters.
Above-described embodiment and graphic and non-limiting product form of the present utility model and style, any person of an ordinary skill in the technical field, to its suitable change done or modification, all should be considered as not departing from patent category of the present utility model.
