4. Flexible stamping automatic line

The flexible stamping automatic line is mostly composed of a double-action stretching press or a multi-link single-action stretching press and 4 to 5 single-action presses to produce a large body cover, which has high safety and good stamping quality. The automatic loading and unloading system is arranged on the production line, which consists of a destacking machine, a cleaning and oiling machine, a centering feeder, a loading and unloading robot (robot), and a shuttle (flip) conveying automatic conveyor, from the blanking of the blank to the stamping The lines are all done automatically. The production cycle is up to 6~9 times/min. The entire press line is about 60 to 80 m long and requires about 6 to 7 operators.

Some companies use internationally advanced high-speed compact press lines to quickly increase the productivity of presses. Sheet centering is positioned using today's advanced optical camera systems. The drawing press adopts CNC hydraulic stretching pad. Each advanced automation unit is equipped with a robot, which eliminates the shuttle conveyor, shortens the conveying distance, reduces the spacing of the press, and produces a production beat of up to 10 pieces/min.

With the intensification of competition in China's auto market, it is an indisputable fact that the appearance quality and intrinsic quality of automobiles have become the preconditions for auto manufacturers to compete in the market. Therefore, the use of mechanized and automated production methods for stamping production is to improve the appearance of automobiles. The most effective way of quality.

5. Commissioning press

High-volume automotive stamping enterprises should configure commissioning presses for each large-scale stamping automatic line to shorten the trial-time of metal forming molds and increase the starting rate of large-scale press lines.

The debugging press mainly selects the hydraulic high-speed test press and the stretching mechanical press, especially the mold test time on the production type mechanical press can be reduced by 80%, which has great application value. The development trend of the trial-type mechanical press is to use a multi-link stretching press equipped with a numerically controlled hydraulic stretching pad, with parameter setting and state memory function.

Mechanized system

The development of the automatic stamping production line, the mechanized transformation of the stamping production line, and the manufacture of large vacuum feeding punching machines for the production of automotive side panels have contributed to the rapid development of the automotive industry.

For domestic automotive stamping parts manufacturers, the most valuable technology upgrades are concentrated in the automated transportation of stamping parts, automated transfer devices and in the stamping equipment loading automation and product-oriented stamping production process.

Since the limit of hydraulic technology is not easy to break through during the deformation process, it can only benefit from mechanical automation, and it is not only beneficial to mechanical automation in the stamping process, but also to the field outside the stamping process technology. The method of transferring stamping parts and the way of going to the stamping parts are beneficial, and the benefits are obtained in all areas where economic benefits can be obtained.

The new integrated rapid transfer system (see Figure 4) allows direct transfer between the press and the press, with a production cycle of 12 to 15 times per minute. The end of the robot arm can be automatically programmed for angle adjustment to accommodate the mold slot position of the mold. In the production process of large and extra large stamping parts, the strong and powerful stamping parts conveying mechanism can be widely used in the production process of large workpiece stamping and two-piece stamping (one stamping of two finished products), and also in the car. Widely used in the production of parts. The swing arm type stamping part conveying system will greatly support and help the stamping equipment in the quick change of the mold. It realizes the simultaneous output of the stamping die and the workpiece, thus laying a foundation for the realization of the multifunctional stamping production line.
