The adjustment plate of the angular bearing box of 40 ton trackless handling vehicle is planed and adjusted. Each bearing seat surface is milled. The car sets are paired. The welding is stopped on the platform. The tooling fixture is used to ensure the geometric size and control the welding deformation. The processing of 40 ton trackless handling vehicle operating mechanism, the processing of the electric flat car operating structure, the important part of this part is the gear coupling, the processing of the gear coupling. We use Y3150E, Y3180H and Y54A fine gear hobbing machine and fine gear shaping machine to process the internal and external teeth The tooth surface is treated by high-frequency quenching, and the 3101 gear measuring instrument is used to stop the comprehensive detection, and the accuracy can reach more than 6 grades. The 50SiMn alloy material is used for the wheels of the electric flat car. We have exclusively used the equipment to stop the heat treatment, which has a positive effect to ensure the hardness of the wheel tread and the depth of the hardened layer. Through the accumulation of long-term use experience of customers and the summary of 100% of the company's customer feedback system, the overall tabletop of 40 ton trackless handling carriage, especially the tabletop that has been subjected to concentrated loads for a long time, in the place where there is no support rib, the tabletop will have pits, namely: The flatness of the table is gradually reduced. After understanding this situation, the engineers of our company calculated the concentrated load of electric flat cars of different tonnages through the size of the table. In addition to the model of the main rib, the mesh plate grid was added to make the local concentrated load exceed the whole The rated load of the car. The detailed pictures are as follows: Through the concentrated load test, the use requirements of this product update can be fully met. The products of our company's level cars have all been changed to safer, more reliable, and more sturdy flatbed tabletops. Of the deformation of the flatbed table.
