Abstract
Along with the development of the construction industry, construction machinery as a modern industrial and civil buildings and the construction of the production process indispensable equipment. Building production and the construction process mechanization and automation, reducing the construction site with the labor intensity, improve labor productivity and lower production cost of construction for the development of the construction industry has laid a solid foundation. As construction machinery for the construction industry to provide the necessary technical equipment, So as the construction industry to measure productivity levels are an important sign, and to ensure project quality, lower construction costs, enhance economic efficiency, social benefits and speeding up the pace of construction provides an important tool. Therefore, the design of construction machinery and research is of great significance.
In this paper, the bar straight for the design of a more systematic study Straightening of reinforced plane were classified and comprehensive presentation; Straightening of reinforced machine control system outlined; Straightening of reinforced the working principle for the analysis of the system; Straightening of reinforced machine power calculation and allocation, Analysis, structural design, the design of the key parts and choice of detail. In light of the actual production of the needs of the overall product structure and properties of the optimal design, reached a relatively sound design requirements, the final straight of reinforcing bars for the overall test.
The design of reinforced Straightening motor-driven machine for cutting scissors bar helicopters, Straightening for the diameter of 14 mm disk or drawing a round of reinforced steel bars. As required length automatically and directly cut, the transfer process will be reinforced direct oxidation of the surface skin, remove rust and dirt. Make full use of its good mobility, small size, simple operation, high efficiency, improving the speed, Construction quality assurance at the same time, reducing manual and materials costs, reduce labor intensity and improved labor productivity.
