Pupil school bus manufacturing process

Pupil school bus manufacturing process

  Most school bus schoolchildren have adopted assembly line production methods. However, the output and size of each factory are different, and the adopted process flow is also different. The common process flow can be classified into three categories.

The most important feature of the first category is that the body and the chassis are made separately. The finished body assembly is then snap-connected with the chassis assembly to enter the interior and exterior trim assembly. The process can save a large amount of production-occupied chassis assembly compared with the primary school bus manufacturing process in which the primary school bus skeleton is welded on the chassis assembly; in order to achieve a whole body pre-treatment and a new process such as medium and high temperature baking. Created conditions; at the same time, it is beneficial to spray the paint on some inaccessible corners and improve the quality of body painting.

The second type is that the finished painted body will be installed with suspension, front axle, rear axle, engine, transmission and other assembly in sequence, and enter the interior and exterior trim assembly. This production method will greatly increase the workload of primary school bus assembly. This process is often used for primary school bus production with a full load-carrying body of grille undercarriage and skeleton welded with profiled steel tubes .

The guardrails in the primary school bus were all softened and the small handles behind the traditional seats were all cancelled and the guardrails in front of the car were raised. Kindergarten seats for kindergartens are equipped with seat belts. Each seat is equipped with a safety belt. The size of the school bus seats and handrails are designed according to the child's height and size. The infant school bus is equipped with a panoramic mirror and all blind spots can be seen. Because schoolchildren are small, they do not see danger when they drive or turn.

The third category is the most common form of production in the past and it has so far been applied to some of the smaller companies. The biggest feature of this process is the welding assembly of the body assembly on the chassis assembly. The chassis will enter the painting workshop along with the body to carry out body coating. In the process of painting the body, it will inevitably cause "pollution" to the chassis; Due to the presence of plastic parts, the drying temperature should not be lower than 90 degrees Celsius; the overall pre-paint treatment technology cannot be used. The quality of car body coating is inferior to the above two process flows; and the number of occupied chassis in the school bus production process for primary school children will greatly increase, which will increase the production cost.
