Product Description Product DescriptionWhat is the bus welding line?The welding of the large bus body is a crucial step in the production process, and the quality of body welding plays a significant role in determining the overall quality of large buses. The large bus body consists of various components such as the bottom skeleton, left/right peripheral skeleton, front/back peripheral skeleton, and top peripheral skeleton. These six major skeletal pieces are welded together to form a sturdy framework for the bus body.The process flow is as follows: prefabrication of six-piece skeleton → group welding of body hexahedron → supplementary welding → welding of all kinds of small parts → grinding of weld seams, skeleton correction → skeleton pre-treatment as a whole → (welding of the inner skin → pre-treatment of the inner skin →) welding of the left/right side of the skin → welding of the front/rear perimeter of the skin → researching and installing all kinds of door parts → sent to the painting workshop for the body top coating.Detailed Photos Bus Skin Roller Press EquipmentSkin roll forming equipment is divided into : top and middle skin roll forming equipment, top and side skin roll forming equipment, and side enclosure skin roll forming equipment.Passenger car body skin roll forming process is the use of roll forming equipment will skin roll forming, through the roll pressure to make the skin reach the cross-section requirements of the drawings of the special equipment, and then after the roll forming of the skin welded to the body skeleton.The main advantage is that the welded parts of the skin and the skeleton are not exposed, and the deformation of the welded parts does not affect the flatness of the outer skin. The width direction can be adjusted numerically. The skin roll forming process effectively improves the surface quality of the body and reduces the amount of scraping, reducing production costs, while the body can be achieved at the same time the lower edge of the skin of the body of the large curvature of the modeling needs, the process is one of the current domestic and foreign passenger car technology and process development trend. Bus Six-side Body Skeleton CNC Assembly EquipmentThe six-piece skeleton group welding is the key process in the production of bus body welding, where multiple structural components are welded together to form a sturdy and functional framework for the bus body. This equipment consists of a body frame positioning mechanism, left/right side frame clamping mechanism, front/rear periphery positioning mechanism, top periphery lifting device, and power system. The body welding assembly generally has a side enclosure production line, frame production line, main line, etc. The production line is equipped with welding equipment as well as tools, fixtures for positioning and clamping, a quality inspection and control system, safety protection devices, and a transport system. Bus body skeleton assembly is a common production process used by bus manufacturers in mass production, and it is also the main way to improve the efficiency of the production line. The six-piece skeleton group welding equipment meets the two production processes of chassis and shell body and can be used for on-line production (when using the on-line production process with chassis, it needs to be equipped with additional chassis lifting and positioning devices). This process requires precision, adherence to welding standards, and rigorous quality control to achieve optimal results. Bus Skin Tensioning EquipmentBus skinning equipment is specialized equipment used in the bus manufacturing process. In bus manufacturing, the skin usually refers to the outer covering plate or shell of the vehicle, which is used to cover and protect the internal structure and components of the vehicle. Bus skin is an important platform to show the quality, appearance, and modeling of the outer surface of the body, its surface flatness determines the quality of the bus and the effect of body modeling, high-quality skin can effectively improve the performance of the body sealing, noise reduction, and strength, and can ensure that the welded area is flat and wrinkle-free to enhance the quality of welding. Skin production is a key production process in bus manufacturing.Skin-pulling process production mainly has a cold-pulling method and a hot-pulling method. Cold tensioning refers to the bus skin at room temperature through the role of mechanical force, so that the bus skin achieves the process parameters, and then through riveting, welding, or resistance spot welding will be fixed with the skin and the skeleton of the operation; hot tensioning the use of the skin of the principle of thermal expansion and contraction, the skin is heated to elongate the skin, the heat will be fixed at both ends of the skin of the bus, the natural cooling of the skin contraction and tensioning to achieve the bus skin of the flatness. Flatness. Automatic Spot Welding of Bus SkinsIn the bus manufacturing process, after the skeleton and skin are positioned on the equipment and the skin is tightened by the hydraulic tensioner, the skeleton is transferred to the spot welding station by the skeleton transfer vehicle, and the roof skin and the skeleton need to be welded together by means of resistance pre-spot welding.Prior to automatic pre-spot welding of the skins, it is first necessary to ensure that the positioning of the skins is accurate and stable. This involves the use of special fixtures or positioning devices to secure the skin to the welding fixture to prevent shifting or distortion during the welding process. By automatically welding the top skin in the processes of tensioning, spot-fixing, automatic spot-welding, supplementary welding support, opening, flanging, grinding, etc., the method effectively improves the firmness and reliability of the weld quality of the top skin of the bus, reduces the risk of de-welding of the skin, and improves the production efficiency and reduces the labor intensity.Bus Welding Power LineThe steel structure and power control system adopt columnar ground structure, the columns are welded with high-quality thick-walled square tubes to ensure support strength; the upper net frame is welded with high-quality square tubes, and the net frame is laid with secondary pipelines, illumination, fans, lamps, etc. according to the needs to satisfy the needs of compressed air, carbon dioxide, and electrical equipment in the production.The ground column power grid adopts the structure of ground columns. The ground columns are fixed on the ground by ground-embedded plates or chemical anchor bolts. This structure is mainly for workshops where the steel structure of the factory roof does not have a preset hanging point. It will occupy a part of the ground space and have a certain impact on logistics transportation. The steel structure consists of two parts: the column and the upper grid. The column is equipped with a power box, air source point, fan, etc. The upper grid is equipped with components such as a compressed air main pipeline, cable tray, lighting fixtures, spiral electric pipe, and spiral air pipe. The power box on each column is equipped with a power switch, lighting switch, fan switch, etc., which can realize partition control and meet the production line's needs for power supply (AC380V, AC220V), air source (compressed air), lighting and working environment improvement (fan).Bus Welding Fume Collection and Treatment LineFume is a very complex substance, welding smoke is very harmful to the human body, and toxic substances are seriously devouring human health. In order to protect the health of the staff and in line with the relevant occupational disease protection norms, it is necessary to collect the welding fume and dust generated in the welding area of this grinding station. The Bus Welding Fume Collection and Treatment Line is a crucial component of bus manufacturing facilities to ensure that welding fumes are effectively captured, filtered, and treated to protect worker health, comply with regulations, and minimize environmental impact.No.ItemParameter1Dust collector modelC-4-782Handling air volume49200m3/h3Quantity1 unit4Number of filter cartridges / pcs4 pcs5Filtering wind speed0.5m/min6Equipment resistance Pa<12007Equipment specification mm7000*14000*45008Optional fan modelSelect fan model9Optional fan parametersFan Model: TFH-ZAir volume: 50000 m3/hFull pressure: 4500 PaRotating speed: 1650 r/minMotor power: 90kwOur Advantages1.
