Research And Application On Manufacturing Process Of Bearing Beam For Pavers

In recent years, as the state strives to develop traffic and transport enterprises, a large number of construction projects for building maintenance and construction machinery demand have significantly increased. The asphalt concrete pavers as one important equipment which can increase productivity and ensure the quality in road construction, their technical level are more and more concerned by people. The bearing beam as the support to the walk in the paving process, its stability and straightness of walking play a very important role in the quality of road surface. And the manufacturing quality of the bearing beam has a direct impact on the walking swing and deviation of the bearing beam.This article is based on the analysis of the overall manufacturing process of bearing beam, focused on analyzing several impact factors about paver bearing beam's manufacturing quality, it provides integrated technology means to enhance the manufacturing quality of bearing beam, and has achieved the expected purpose.(1) From the overall planning process proposed new ptimization process. From the bearing beam of the force structure, finite element analysis using ANSYS solid modeling software, analysis the bearing beam of the force-deformation, raised bearing beam in the welding process need to focus on the control of the weld.(2)? On the welding process, designed welding equipment to ensure that butt size requirements. Analyzed welding pieces of material, groove forms, welding parameters current, voltage, welding speed and other aspects, and focus the beam from the welding sequence on the overall deformation. Drew an optimized and reasonable welding technology from a lot kinds of welding, testing, statistical analysis.(3) The use of the robotic welding technology to replace the traditional manual welding, welding parameters and welding locking order to reduce the welding deformation, control the allocation of a reasonable allowance after welding to ensure the welding quality.(4) Planing the bearing beam processing technology and equipments. Contrasted the new and the old two processing methods. Determined the processing benchmark and adjusted the processing sequence to ensure the installation check reducer mouth and the bottom of the plane perpendicular to the plane of the floor and their degree and straightness requirements.
