Four applications of integration of industrial robots and CNC machine tools
the automotive industry has always been the most important field of robot applications. With the improvement of automation demand, the application of industrial robots has been expanded. In addition to traditional welding applications, robots have also been widely used in machine tool loading and unloading, material handling and stacking, grinding, spraying, assembly and other fields. Metal forming machine tools are an important part of machine tools. Forming processing is usually associated with high labor intensity, noise pollution, metal dust, etc. sometimes it is in a high temperature, high humidity and even polluted environment. The work is simple and boring, and it is difficult for enterprises to recruit people. The integration of industrial robots and forming machine tools can not only solve the employment problem of enterprises, but also improve the processing efficiency and safety, and improve the processing accuracy, which has great development space
integrated application of CNC bending machine
there are two main ways of integrated application of robot bending. Organic flame retardant and inorganic flame retardant are centered on the bending machine. The robot is equipped with vacuum suction cups, and the magnetic tension loading frame, positioning table, unloading table and turnover frame form a bending unit. The second is the flexible processing line of plates formed by robots and laser equipment or CNC rotary table punches, industrial robot walking shafts, sheet metal transmission lines, positioning tables, and vacuum suction cups. Esther used his technology in robot control system and machine tool numerical control system and the platform with insufficient industrialization to realize seamless connection, developed bending software package, and realized closed-loop control of robot feeding in the bending process. At different bending speeds, the robot realizes complete tracking of automatic matching, and the bending software package also shortens the bending teaching time from days to hours. It is well used in the processing of switchgear, filing cabinet, elevator, anti-theft door, etc
press integrated application
there are two main ways of robot and press integrated application. One is the stamping loading and unloading of a single robot: the sheet metal is moved from the destacking platform to the positioning platform by the robot, and then transferred to the press die for stamping after positioning. After stamping, the material is taken by the robot and put into the stacking platform to realize the automatic loading and unloading of a single press robot. The second is robot stamping connection: establish stamping connection between multiple presses through multiple robots. According to the requirements of workpiece forming process, it needs to be processed with multiple presses. The whole production line is composed of destacking robot, feeding robot, transmission and handling robot between presses, and tail line robot. Compared with the manipulator with linear coordinates, the industrial robot is more flexible, has no high requirements for molds, and is easy to integrate. Esther uses the autonomous press control system and the robot control system to seamlessly connect, so that the robot's action and the press can achieve the best coordination. Using the fieldbus, the efficiency of the whole production line can be maximized and the safety is higher
integrated application of hot die forging
hot die forging production line is usually composed of two die forging presses, one for stamping and the other for trimming. The integrated application of hot die forging robot is usually equipped with two robots, one is responsible for transferring the high-temperature materials processed by the medium frequency furnace to the stamping die forging press, and the other is responsible for transferring the materials from the stamping die forging press to the other die forging press for edge cutting. In order to prevent the high-temperature stamping workpiece from sticking to the mold, it is necessary to lubricate the mold with graphite after each stamping. The lubrication can be completed by robots or special institutions. Because the forging is a harsh environment with high temperature and humidity and graphite lubrication, special attention should be paid to the protection work of the robot and the anti heat radiation ability of the human body through what principle the machine general torsion tester works. The robot shaft motor of Easton company has the structural characteristics of self avoiding heat radiation at the junction of the robot arm and forearm. The electronic cam control system is installed in the die forging press to coordinate the operation of the die forging press with the operation of the robot, improve the processing efficiency and improve the safety of the system
welding application
welding is the subsequent process of sheet metal processing of forming machine tools. There are two types of robot welding: resistance welding and arc welding. The application of welding robot accounts for more than 40% of the whole robot application. The application of arc welding takes robot as the core, and the welding workstation is composed of welding machine, wire feeder, welding gun, tooling fixture, etc. Easton can provide 6kg special arc welding robot workstations with arm lengths of 1400, 1600 and 2000mm. The application of resistance welding is based on the robot, which is equipped with spot welding gun, welding controller, water and gas unit, pipeline package, tooling fixture and other components to form a spot welding workstation. Eston can provide a special resistance welding robot workstation with 220kg and 2600mm arm length. In addition, such super performance materials as Aston automation also show a series of multi-functional properties. The department develops a special welding software package for welding applications, integrating the welding expert process parameter library into the robot system to meet various types of needs
robots are typical representatives of advanced manufacturing technology and automation equipment. Intelligent industrial equipment has become the basis for the upgrading and transformation of the global manufacturing industry. The integrated application of industrial robots and CNC machine tools makes intelligent manufacturing and digital workshops and intelligent factories from concept to reality
