Description
Technical Field
The utility model relates to a road roller driver's cabin part, specifically speaking are B post mechanical tubes for driver's cabin.
Background
At present, the application of the special-shaped steel pipe is more and more emphasized by people, and the special-shaped steel pipe is widely applied to the industries of vehicles, ships, agricultural machinery, engineering machinery, textile machinery, food machinery and the like. But also there are more and more places where profile pipes are used in the cabs of various construction machines. The special-shaped steel pipe is formed by bending a cold-bending formed closed section in a cold state, so that the special-shaped steel pipe has the advantages of energy conservation, metal material conservation, convenience in construction, attractive appearance and the like, is more substituted for angle steel, channel steel, I-shaped steel and round pipes in recent years, and is widely applied to various building structures and mechanical facilities.
The shape of the early engineering machinery cab is simpler, the shape lines mostly adopt the form of combining straight lines and edges and corners, however, with the advance of technology and the improvement of the manufacturing process level and the introduction of aesthetic design concept, the appearance of the cab of the engineering machinery has changed from the early straight line type to the arc type, the framework structure of the steel tube is gradually and massively replaced by cold-bending special-shaped steel tubes which are welded together by square tubes, round tubes and the like to achieve the effect, because the cold-bending section is an economic section, the section can be formed into a complicated section, and the frame is made of the special section, the vehicle model is beautiful and elegant, the cost is reduced, the surface is smooth and clean, the size precision is high, and the cold-bending section bar has the excellent functional characteristics of large section modulus, good torsion resistance and impact resistance and good stability, and the cold-bending section bar customized individually can be widely used in the manufacturing of engineering machinery cabs.
With the development of manufacturing industry in China, new product export is increased, the product quality is required to meet the requirements of Europe and America, and a cab formed by special pipes is required to be suitable for operation in cold regions, so that the tests of a cab rollover protection structure (ROPS) and a Falling Object Protection Structure (FOPS), which are often called destructive tests, are required to be met. So adopt the cold-formed mechanical tubes that will adopt high strength material to process to make the driver's cabin, make the design of driver's cabin more free and nimble on the one hand, the driver's cabin is safer and spacious, on the other hand for the driver's vision is wider, and the operation is convenient high-efficient more.
The appearance of the early cab is simpler and is mostly of a box-type structure, but with the improvement of the technology, the improvement of the manufacturing process level and the introduction of the aesthetic design concept, the appearance of the forklift cab is changed from an early linear type to an arc shape so as to adapt to some functional requirements of the cab, such as aerodynamic, wind resistance reduction and space utilization rate increase. The existing standard square tube cannot meet the requirement of a forklift cab on skeleton arching, is single in shape, cannot fully utilize the space of the forklift cab built by the standard square tube, and is not strong in mechanical properties such as bending resistance and torsion resistance. And some pipelines need to pass through various lines, and are easy to be confused if being square pipes. With the technical progress, the improvement of the manufacturing process level and the introduction of the aesthetic design concept, the shape of the cab of the road roller is changed from the early linear shape to the arc shape so as to meet some functional requirements of the cab, such as aerodynamics, reduce wind resistance and simultaneously increase the space utilization rate. The B-pillar of the cab is also called a center pillar, and is located between the front door and the rear door. It is also stressed by the roof and front and rear doors, and additional parts are added to the B-pillar. Therefore, the contradiction of the B column is that the balance between rigidity and weight is achieved, the existing B column has a single structure and is not strong in mechanical properties such as bending resistance, torsion resistance and the like.
