Yesterday, the reporter saw in the first-phase plant of Great Wall Motor Co., Ltd. Tianjin passenger car production base (hereinafter referred to as “Great Wall Tianjin Baseâ€) that the first phase of the project had been completed and that 250,000 complete vehicles were built in the first phase of the vehicle. In the production line, there are four new workshops for stamping, welding, painting and assembly, and inspection workshops, and joint power station buildings. In the spacious and bright factory, the workers are working on equipment commissioning. Three Tengyi C50 sedan cars were assembled on the production line and dozens of workers performed installation work in different steps. Wang Jixian, the project leader of the base assembly shop, introduced that the Tengyi C50 sedan has entered the stage of joint debugging of the equipment and uses the joint debugging process to improve employees' awareness, recognition and equipment skills of the models. The main purpose of the joint debugging phase is to debug the production line. .
Liu Bin, deputy general manager of Great Wall Motor Co., Ltd. Tianjin Branch, introduced that the Great Wall Tianjin Base has a total investment of 12.67 billion yuan and occupies an area of ​​5,000 acres. The project consists of a vehicle park and supporting parts park.
High Speed Injection Molding Machine
The high speed Injection Molding Machine adopts the hybrid type of gasoline pump and servo motor. The software of servo hydraulic system has the following advantages: it is not easy to cause damage to the power network by implementing soft starting abrasives, and it can prevent the environmental pollution of working voltage and electric radiation; It can reasonably avoid excessive water temperature and has excellent temperature reduction; Greatly reduce the replacement rate of gear oil.
The servo hydraulic system software can reduce equipment operation and production noise and improve the office environment because it has a good click and power supply system gear oil pump. Compared with the general injection molding machine, the total power consumption of high-speed injection molding machine can be saved by 60~70%, greatly reducing the cost.
Generally speaking, high-speed injection molding machines are all motors. Generally, injection molding machines are all hydraulic injection molding machines, and the relative operation speed of hydraulic injection molding machines is relatively slow. The servo motor of the all-electric high-speed injection molding machine is used to complete mold opening and closing, ejection and demoulding, and raw material injection and storage. The operation speed is fast and high-precision, further improving or improving the working environment and productivity. But now, servo electric injection molding machines only have equipment with clamping force below 850 tons.
