A servomechanism, also known as a follow-up system, is a feedback control system designed to accurately follow or reproduce a process. Servo system an automatic control system that enables the position, orientation, state and other output controlled quantities of the object to follow arbitrary changes in the input target (or a given value). Its main task is to magnify, transform and control the power according to the requirements of the control command, so that the torque, speed and position control of the output of the drive device is very flexible and convenient. Servo system in many cases, the amount of points to be controlled (system) of the output is the mechanical displacement or displacement velocity and acceleration feedback control system, its role is to make the output of the mechanical displacement (or Angle) to accurately track the input displacement (or Angle), its structure and other forms of feedback control system there is no difference in principle. Servo system was initially used in the national defense industry, such as gun control, ship, aircraft autopilot, missile launch, etc., and then gradually promoted to many sectors of the national economy, such as automatic die-casting production line, wireless tracking control, etc. First, the main role 1. Control high-power load with low-power instruction signal; 2. In the absence of mechanical connection, the input shaft controls the output shaft located in the distance to achieve remote synchronous transmission; 3, make the output mechanical displacement accurately track electrical signals, such as recording and indicating instruments. Ii. Development history Servo is a shortening of ServoMechanism, which comes from Greece and means slave. As the name suggests, ServoMechanism refers to the system following external instructions to perform the desired motion. The motion factors include position, speed and torque. Reviewing the development history of servo system, from the earliest hydraulic and pneumatic to the current electrification, servo system composed of servo motor, feedback device and controller has gone through nearly 50 years. Nowadays, with the continuous maturity of technology, AC servo motor technology with its excellent cost performance, gradually replace DC motor to become the dominant motor servo system. The mature technology of AC servo system also makes the market show a rapid diversified development, and become one of the supporting technologies of industrial automation. 3. Die-casting machine equipped with servo robot

In casting production,industrial robots can not only replace people in high temperature, pollution and dangerous environment, but also improve work efficiency, improve product accuracy and quality, reduce costs, reduce waste, and can obtain flexible and durable high speed production process. Longhua technology will be casting technology, casting equipment, industrial robot organic combination, continuous research and development of casting projects in the field of application, has covered die casting machine automation, die casting casting, casting grinding and other fields, mainly involved in core making, modeling, cleaning, grinding, transport and palletizing processes. 1. Gravity casting -- new servo ladle machine The traditional casting mode of gravity casting is artificial spoon to take liquid aluminum casting, high temperature, large handling strength, especially large castings need two spoons to take liquid aluminum casting. This mode will cause poor stability of casting process and fluctuation of casting product quality due to the limitation of operator's physical ability. Not only manpower is too much to bear, quality is also affected. And the use of industrial robot casting, by the robot pouring management software automatic control of the robot according to the set of casting process, product repeatability is consistent, greatly improve the quality of products, the liberation of labor. · 2, die casting machineextract-- new servo auto extractor Die casting workshop high working temperature, labor intensity, the use of robots to replace manual picking and spraying operations, can improve production efficiency and reduce the dependence on manual, more and more die casting factories began to use robots in the die casting link. 3. Die-casting demoulding machine -- new servo auto sprayer The demoulding process in the production of traditional investment casting is generally completed by manual. Some demoulding agent has heavy weight and large labor intensity, while industrial robot has high movement accuracy and large load quality, which can replace manual demoulding operation of die casting parts. Automatic robot in casting production has the characteristics of improving working conditions, saving labor, reducing scrap rate and product cost, improving productivity and product quality, ensuring production safety, accelerating product renewal, and reducing equipment loss, saving resources, clean production and so on.Therefore, improve the level of automation in the foundry industry, strengthen the application of industrial robots in the foundry industry, so as to achieve clean production, increase enterprise benefits. Bengbu Longhua die casting Machine Co., Ltd. has mature experience and technology in the application of automatic die casting machine industry, and is a strong partner of large casting enterprises to realize machine replacement and intelligent production. Longhua, let the world love Made i...
