Compared with the traditional press (see Figure 2), the servo multi-station press mechanism (see Figure 2) reduces the components such as the flywheel and clutch, and directly drives the motor with high dynamic performance torque to drive the slider to realize the working mode production. . The traditional press drive is to transfer energy to the main shaft by the flywheel. In contrast, the servo multi-station press structure is simpler and easier to maintain. In the absence of work, the servo multi-station press torque motor does not need to operate, its energy consumption is almost zero, and the traditional mechanical pressure opportunity produces a part of useless power consumption. Even when machining the same workpiece, the conventional mechanical press is limited by the mechanism, and the corresponding slider can only reciprocate up and down at the maximum stroke. However, the servo multi-station press can change the motion curve flexibly according to the process requirements. 1. Comparison of motion curves For the traditional mechanical press, the motion curve is shown in Figure 3. The traditional mechanical press features: the stroke speed is not adjustable; the stroke length is often fixed. However, the fixed speed has the same forming speed and motion profile for all geometric components. Traditional mechanical presses lack production flexibility in terms of increased production. In contrast, the servo multi-station press motion curve, as shown in Figure 4, can adjust the appropriate slider stroke according to the drawing depth of the stamped product. The variability function of the servo multi-station press motion curve provides technical support for the improvement of production tempo and product quality, and its real-time dynamic torque also increases product output. 2. Servo multi-station press advantage display (1) Modification and optimization of stroke length and curve in single pendulum mode single pendulum mode: The pendulum stroke length can be freely programmed, the forming process is optimized, and the single pendulum mode can also increase the yield, as shown in Fig. 5. By setting the most suitable slider motion mode (such as the single pendulum mode) for different metal materials, it is possible to press and form difficult-to-machine materials such as high-strength steel materials, aluminum alloys, and titanium alloys used in the manufacturing industry. (2) The adjustable speed curve of the mold opening stage optimizes the mold debugging time, optimizes the blanking or forming speed, and optimizes the process reliability and product quality (see Figure 6). (3) Trial model is tested by handwheel: the slider speed can be adjusted when the mold is installed, the slider can be controlled by reverse motion, and the debugging can be started from the rated pressure. The slider has the function of “fast lifting†to meet the fast. Modulation commissioning production requirements (see Figure 7). The servo multi-station press also has the advantages of improved material forming limit, process saving, noise reduction and shock absorption, and high safety. As shown in Fig. 8, the servo press is used, and its motion curve is as shown in Fig. 9. The production efficiency is improved by 60%, and the mold contact speed is lowered. In addition, the forming speed stabilization process is reduced, the mold loss is reduced, and the capacity limitation and feeding speed are also improved. It can be seen from the example analysis that the servo press has full flexibility advantage over the traditional mechanical connecting rod press: 1 high output can flexibly increase production and speed. 2 Controllable elements increase the process of improving the drawing. 3 Reduce mold wear and reduce mold maintenance costs. 4 can flexibly integrate other forming processes to optimize the production process. 5 servo presses have a good economic advantage due to the increase in production tempo. At present, the servo multi-station press is mainly used for production lines and test modes such as drawing, blanking, bending, cold forging, etc., and the position, speed and output pressure of the slider are controlled by a computer, so that high-strength steel plates are used in automobile manufacturing. Large-size cover parts of aluminum alloy sheets are made possible. Controlling the movement track of the press slider not only improves the life of the mold several times, but also improves the working environment of the press, reduces noise and vibration, and provides a broad prospect for broadening the new metal forming process and mold manufacturing method. From the point of view of actual production and application, the servo multi-station press is more than 30% energy-saving than the traditional press, and the noise generated is also greatly reduced. It is a safe, energy-saving and environmentally friendly press. And because it can realize flexible processing, no matter the complex process such as drawing, punching and pressure keeping, it can be realized. According to different materials, different processes can set appropriate processing curves, which are not only widely used, but also have sufficient stroke in the slider. In the case of the machine can also completely replace the mechanical press. With the application of new materials, process technology development and global attention to energy conservation and emission reduction, servo multi-station presses are uniquely advantageous in these respects, and will gradually replace traditional mechanical presses and become widely used. A semi-Flush Mount is a type of light fixture that is installed on the
ceiling and hangs down slightly, but not as far as a Pendant Light. It
is a popular choice for rooms with low ceilings, as it provides ample
light without taking up too much vertical space. Semi-flush mounts come
in a variety of styles and designs, from modern and sleek to more
traditional and ornate. They are typically easy to install and can be
used in a variety of settings, including bedrooms, living rooms, and
kitchens. Semi-Flush Mount,Ceiling Mount Lighting,Ceiling Flush Mount Light Fixture,Led Ceiling Flush Mount Light Zhengdong Lighting Co., Ltd. , https://www.sundint.com
