Bus Welding Line

Bus Welding Line Introduction
Bus welding line is the process of making the bus body frame and skin. The square pipe is cut into the corresponding length according to the process requirements from the blanking workshop, and the frame is welded into six large sections of the body using the cnc assembly equipment for buses, including the left side frame, the right side frame, the top frame, the front frame, the rear frame and the chassis frame. Generally speaking, the chassis frame will be welded into 3 section sub-assembly. and then welded into the chassis assembly. Finally, the six large pieces are assembled into the bus body skeleton through the composite tire, The bus skin is then making by the rolling machine. and the shape and size required by the cusomer is made using a rolling mechanism, and the current bus manufacturing process also requires the skin to be strength and welded to the bus body. The welded bus body will enter the bus painting line.
China vehicle industry co.,ltd has the whole catalog for the bus welding line equipment, and will design you the suitable layout and also the 3D design for the jigs and fixtures. Feel free to contact to get the design and price now !

Bus Painting Line

Bus Paint Line is the most important working process in the whole bus production line. And also the most expensive equipment in the whole production equipment. After the bus welding line, the bus body and skin need to be treated by cathode electrophoresis, so that the vehicle has a high intensity oxide film. In the salt spray test can resist corrosion for more than 1000 hours, after the electrophoresis of the body into the spary station, respectively primed, middle painted, top painted, and heating. Many customers also have color strip paste stations, so that the vehicle is more beautiful, but also can increase the customer's special logo or decoration, In recent years, there are also some bus factories that use all-aluminum bodies, because the meterial itself has corrosion resistance, so the all-aluminum body does not need to be treated by electrophoresis.

Bus Assembly Line Introduction
Bus assembly line is to install all the parts to the bus body, just like the wiring system, the floor, the seats, the doors, the headlight, the AC, the axle, the tyre and the glass. Normally the bus assembly line is also the tour rote for most visiters. The use of power assisted manipulators can be increase to reduce the work intensity of workers, and according to the production rhythm, EMS system and plate chain conveyor systems can be used. At the same time, the axle and the engine are also installed in the final assembly line. China Vehicle Industry Co.,ltd has the muti-direction adjustable engine mounting trolley, and the alxe lifting trolley to make the installation of the entire power system more accurate. Please contact our customer service for more information.

Key equipment for Bus Production Line

Bus Skin Rolling Machine

Bus skin rolling machine is the equipment to make the steel plate becomes the skin of the bus body with different shape, which is the shell of the bus that we see. Like side skin rolling machine, top skin rolling machine and top-side skin rolling machine.

The side skin roll forming equipment is a special equipment that makes the skin meet the cross-section requirements of the drawing through the rolling of the mold (roller). The left bearing seat (with roller) of the equipment is fixed as a whole, and the right bearing seat (with roller) can slide left and right as a whole, so as to achieve a multi-purpose machine with adjustable width.

Top Skin Welding Machine

Automatic spot-welding machine for top skin it the key equipment to realize the low position operation of top skin, positioning, stretching, and welding of top skin and the frame.

After the frame and skin are positioned on the equipment and the skin is pulled tight by the hydraulic tension device, the frame transporter transfers the frame to the spot-welding position, and the double-sided single spot-welding machine fixed on the gantry frame and accompanying trolley moves synchronously with the gantry frame and accompanying trolley and presses spot welding. A cylinder is installed on each electrode, and the cylinder presses the skin and skeleton (the pressure is adjustable) between the two electrodes, and through the resistance heat generated by the current flowing through the workpiece contact surface and adjacent areas, it is heated to the melting state, to achieve the purpose of welding parts.

Front/Rear Axle Installtion Cart

The axle mounting trolley( as the axle installation cart) is used for the assembly of the front and rear axle of the bus in the bus assembly line. The assembly vehicle is composed of skeletion, lifting device, walking system, support device, hydraulic systen and control system, with automatic walking mechanism .

The equipment consists of a walking wheel, frame, boom adjusting mechanism, a lifting mechanism and a control system. Two directional and two universal casters( with brakes) are used as walking wheels to drive the walking mode manually. When the crane is stopped, the caster brake mechanism is pressed to ensure the safety of use.The frame is welded with profiles to ensure the strength of use.

Side Skin Hydraulic Strength Machine

The hydraulic tensioning device consists of a mobile clamping system, a fixed clamping tensioning system, a hydraulic system, and electrical control system and other accessory components.

The hydraulic tensioning technology adopts the characteristics of large hydraulic cylinder strength, and can adapt to the needs of relatively large skin thickness and width. Applicable bus panel width: 300mm-1500mm. Applicable bus panel thickness:0.8mm-1.2mm. The equipment strength the side skin of the bus before welding to ensure that the skin free of wave after welding, to improve the appearance quality of the bus body and the overall performance.
