A kind of loader cab front column shape tube

Technical field

A kind of driver's cabin shape tube is the utility model is related to, specifically a kind of loader cab front column shape tube.

Background technology

The application of steel tubes is increasingly valued by people at present, be widely used in vehicle, ship, agricultural machinery, In the industries such as engineering machinery, textile machine, food machinery.And the ground of shape tube is used in the driver's cabin of various engineering machinery Side is also more and more more.Because steel tubes are opening-closed sectional material brake formings under cold state of cold roll forming, shape tube has Save the energy, save metal material, it is easy for construction, handsome in appearance the advantages that, in recent years more substitute angle steel, channel-section steel, I-shaped Steel and pipe, it is widely used in various building structure, mechanical facility.

The engineering machinery driving cabin profile of early stage is fairly simple, the form that profile lines are combined using straight line with corner angle more, But with advances in technology with the raising of manufacturing technology level and the introducing of aesthetics design theory, engineering machinery driving cabin it is outer Shape becomes via the linear pattern of early stage turns to arc line shaped, and its skeleton structure gradually starts the replacement of large-scale use clod wash steel tubes Original structure for using the weldings such as square tube, pipe to form to reach effect, because cold-forming shapes are a kind of economic section types Material, it can be molded complex sections, and make framework using profile shapes, and vehicle is elegant in appearance, reduces cost, surface light It is clean, dimensional accuracy is high, and its section modulus is big, antitorque, shock resistance is good, the good excellent functional characteristic of stability, individual The cold-forming shapes of propertyization customization obtain widely using in engineering machinery driving cabin manufactures.

As China's manufacturing industry develops, new product outlet increase, it is desirable to which product quality is adapted to American-European requirement, and some are using different The driver's cabin that type pipe is formed requires to adapt to operate in cold district, so to meet driver's cabin Roll-Over Protective Structure (ROPS) and fall Thing protection structure (FOPS) test, i.e., we often described in destructive testing.So processed using high-strength material to be used Clod wash shape tube manufacturing engineering machinery drive driver's cabin, on the one hand make it that the design of driver's cabin is more free with flexible, driver's cabin It is safer.

Utility model content

The utility model purpose is to provide a kind of loader cab front column shape tube, and it passes through the structure of uniqueness, car Type is elegant in appearance, reduces cost, and any surface finish, dimensional accuracy are high, and its section modulus is big, has stronger antitorque, anti- Impact and stability.

In order to solve the above-mentioned technical problem, the technical solution adopted in the utility model is：

A kind of loader cab front column shape tube, including body, the body are provided with inner chamber, and the inner chamber is by four Bar identical leg surrounds, and the leg is intermediate symmetry structure, and the leg includes straightway, arc, and connection is directly The linkage section of line segment and arc, the leg are using the middle separated time of arc as symmetry axis, and straightway and linkage section all have Two, and be symmetricly set on the inside of the circular arc at arc both ends, the angle between two linkage sections is acute angle, and is symmetrically set To put on the inside of the circular arc at arc both ends, the straightway is vertical with the middle separated time of arc, in four legs of the inner chamber, Adjacent straightway vertical connection.

Further, the arc radius of the arc is 202mm.

Further, the angle between two linkage sections is 58 °.

Further, the thickness of loader cab front column shape tube is 4mm.

Preferably, the material of loader cab front column shape tube is Q235.
