How is the outer shell of an New Car stamped out?

The press first drives the motor to work through the transmission mechanism. The transmission mechanism is composed of belts and gears to decelerate and increase force. The structure of the transmission mechanism generally includes a screw mechanism, a crank-connecting rod mechanism and a hydraulic cylinder. Therefore, the press is also divided into these three categories. The most common one is the crank press, also called a mechanical press, which is a common type of press.

The mechanical presses generally used on the New Car stamping line are large and have a large load. The weight of the mold to be replaced is also several tons. The force loaded on the body of the New Car parts is often thousands of times the weight of the New Car. The press body must not be deformed. The difficulty can be imagined.

Moreover, a large press costs millions to cast a single body. In order to enhance the transmission capacity, most are equipped with herringbone gears. The lathe used to process a gear is tens of meters long, and the gear shaping process may take several months.

Whether the parts of Fuel Car are extremely large or extremely small, they will have higher requirements for the precision of the machine. The press is a typical large part with complex manufacturing process, high stability and precision requirements, and long manufacturing cycle. It is not easy for Chinese press manufacturers to win the market.
