<br>Abstract: The design of the hydraulic system of the riveting machine of the automobile girder production line : The <br>automobile girder belongs to a kind of automobile chassis structure, but nowadays cars basically do not adopt the design of the girder chassis. Only trucks and buses will use it. There are two channels of steel under the carriage of the large truck, from the front to the rear, that is the beam. The girder is the main load-bearing component of the truck. It almost carries the entire weight of the cargo. The quality of the girder affects the service life and driving safety of the vehicle. The automobile girder is generally stamped and formed. Its deformation method is mainly bending, so the girder The plate has high requirements for formability, that is, the automobile beam steel plate must have good comprehensive properties, sufficient strength and toughness, good fatigue resistance, and cold formability. With the development of the automotive industry, high-strength steel plates that reduce weight and improve safety, new products with excellent strength and formability are the main body of automobile plate demand and development direction, and in order to manufacture high-strength automobile beams, riveting machines become The most suitable choice. <br>The hydraulic riveting machine is mainly used for riveting processing of truck and bus frames, rolling stock, aviation, and mining cars. Especially trucks need to drive on uneven roads. If the welded structure is used, the strength is obviously not enough, so it has to be riveted. Based on the functional requirements of the hydraulic riveting machine, this subject calculated the main parameters of the hydraulic system, and carried out the design of the main hydraulic circuit and the analysis of the action sequence, designed a reasonable schematic diagram of the hydraulic system of the riveting machine, formulated the transmission scheme of the hydraulic system The hydraulic components are calculated and selected according to the system parameters, the system performance and the pressure loss of the hydraulic system are checked, the system temperature is raised, and the main components and the overall three-dimensional structure design of the hydraulic riveting machine are designed. Finally, according to the work process and Control requirements, drawing hydraulic cylinder assembly drawings, hydraulic cylinder parts drawings, hydraulic pump station assembly drawings, to achieve the purpose of designing a complete set of automobile girder production line riveting machine hydraulic system. <br><br>Keywords: automobile girder, riveting machine, hydraulic system

Hydraulic system design of riveting machine in automotive girder production line<br>Excerpts:<br>Car girderbelongs to a kind of automobile chassis structure, but now the car basically does not use the girder chassis design, only the truck, the bus will be used. There are two grooves of steel under the carriage of the big truck, from the front to the rear of the car, that is, the girder. Girder is the main carrying parts of the truck, almost carrying the full weight of the goods, the quality of the girder affects the service life of the whole vehicle and driving safety, the manufacture of automobile girders generally use stamping molding process, its deformation mode to bend mainly, so the girder plate on the molding requirements are higher, that is, the car girder steel plate must have good comprehensive performance, to have sufficient strength, good fatigue resistance, cold molding. With the development of the automobile industry, weight loss and improve the safety of high-strength steel plate, strength and shape are excellent new products are the main body of automotive plate demand, development direction, and in order to manufacture high-quality strength of the automotive girder, riveting machine has become the most suitable choice.<br>Hydraulic riveting machine is mainly used for the riveting process of heavy-duty vehicles and bus frames, locomotives, aviation, mining vehicles, etc. In particular, heavy-duty vehicles need to travel on uneven roads, such as the use of welded structure, strength is obviously not enough, so the riveting work has to be carried out. According to the functional requirements of the hydraulic riveting machine, the main parameters of the hydraulic system are calculated, and the design and action sequence analysis of the main hydraulic circuit is carried out, a reasonable hydro-hydraulic system schematic is designed, the transmission scheme of the hydraulic system is formulated, and the hydraulic components are calculated and selected according to the system parameters, the system performance and hydraulic system pressure loss are verified, the system is heated, and the main components of the hydraulic riveting machine and the overall three-dimensional structure design are carried out. Finally, according to the workflow and control requirements of the hydraulic riveting machine, the hydraulic cylinder assembly map, the hydraulic cylinder part map, the hydraulic pumping station assembly map, so as to design a complete set of automotive girder production line riveting machine hydraulic system purposes.<br><br>Keywords: automotive girders, riveting machines, hydraulic systems

Design of hydraulic system for riveting machine of automobile girder production line<br>Summary:<br>Automobile girder belongs to a kind of automobile chassis structure, but the present automobile basically does not use the girder chassis design, only the truck, the bus will use. There are two channels under the wagon, from the front to the back, that is the girder. The girder is the main load-bearing part of the truck, which almost carries all the weight of the goods. The quality of the girder affects the service life and driving safety of the whole vehicle. Generally, the stamping forming process is used to manufacture the automobile girder, and its deformation mode is mainly bending. Therefore, the girder plate needs high formability, that is, the automobile girder steel plate must have good comprehensive performance, It should have enough strength and toughness, good fatigue resistance and cold formability.
