Description
Technical Field
The invention relates to plastic tank welding equipment, in particular to an automobile plastic vacuum tank welding machine.
Background
Fuel-fired vehicles have long been the dominant force of the automotive industry. However, with the increasing environmental pollution and the gradual depletion of petroleum resources, new energy vehicles are becoming a new growth point in the vehicle market. The transition from the traditional fuel vehicle with high pollution and high emission to the new energy vehicle with zero emission or low emission is a necessary way for the automobile industry. The traditional fuel automobile is mainly vacuumized continuously through the rotation of an engine so as to ensure certain brake assistance, and the operation mode is sensitive. In the existing electric automobile, the engine is replaced by the electric motor, the engine in the hybrid electric automobile is not always operated, and the electric motor cannot rotate like the engine, so the braking effect is far inferior to that of the traditional fuel automobile. Therefore, a brake boosting system, especially a vacuum brake boosting system of an electric vehicle, is required to be provided in the electric vehicle or the hybrid vehicle. The vacuum booster is an important part of a brake boosting system, and the brake pedal force is amplified by a diaphragm type power piston by utilizing the pressure difference between vacuum formed by an air inlet manifold of an engine and external atmospheric pressure to push a brake master cylinder to work. The biggest factor for determining the function of the vacuum brake boosting system of the electric automobile is the degree of vacuum degree provided by the brake system, and the vacuum brake boosting system needs a vacuum source capable of providing enough pressure for the brake system. The magnitude of the boosting force provided by the vacuum booster depends on the magnitude of the air pressure difference between the constant pressure chamber and the variable pressure chamber. When the vacuum degree of the variable pressure chamber reaches the external atmospheric pressure, the vacuum booster can provide the maximum braking boosting force.
Most of vacuum tanks for storing vacuum in the current market are made of iron or stainless steel materials, and the weight of the vacuum tanks increases the waste of energy in the driving process of automobiles. Along with the implementation of the national requirements on energy conservation and emission reduction of new energy automobiles, the light-weight plastic vacuum tank has a larger development space on a vacuum brake power-assisting system; at present, most of plastic tanks are produced by adopting an injection molding process, and plastic parts formed by injection molding are welded to form required parts. Although a large number of welding devices for plastic products exist in the market at present, the welding fineness of the welding devices is not high, and the problems of welding missing, uneven heating or deformation of welding seams and the like are easy to occur; however, the welding of the vacuum tank of the vacuum brake boosting system must have higher sealing performance, and once the sealing performance is poor, the function of the vacuum braking boosting system is reduced and even lost, and more serious traffic accidents can be caused, and the consequences are difficult to predict. For the equipment with higher welding precision, the manufacturing cost is very high, the production cost is not so high, the device is often used for equipment detection in high-precision fields of aerospace and the like, and the device is not suitable for small and medium-sized processing enterprises. Aiming at the technical problems of the existing welding equipment, the company develops an automobile plastic vacuum tank welding machine, and the device has the characteristics of simple structure, convenience in operation, good welding sealing performance, low production cost and high welding quality.
