The automotive industry has always been the most important field of robotics applications. With the increase in automation requirements, the application of industrial robots has been further expanded. In addition to traditional welding applications, robots are loading and unloading materials, material handling palletizing, grinding, painting, and assembly. Other fields have also been widely used. Metal forming machine tools are an important part of the machine tools. Forming and processing are usually associated with high labor intensity, noise pollution, metal dust, etc., sometimes in a high temperature, high humidity, or even polluted environment. The work is simple and boring, and the enterprises are difficult to recruit. The integration of industrial robots and forming machine tools not only solves the problem of enterprise employment, but also improves processing efficiency and safety, and improves machining accuracy. It has great room for development.
CNC bending machine integrated application
There are two main ways to integrate robot bending applications. One is the bending machine as the center, the robot configuration vacuum suction cup, magnetic tension sheet loading rack, positioning table, cutting table, flip frame forming bending unit. The second is the flexible processing line formed by robots and laser equipment or CNC rotary table punching machines, industrial robot walking shafts, sheet material transmission lines, positioning tables, and vacuum suction cups. Eston uses its own technology and platform in the robot control system and machine tool control system to realize seamless connection, develop bending software packages, and implement closed-loop control of robot feeding during bending. At different bending speeds, the robot achieves complete tracking of automatic matching. The bending software package also shortens the bending teaching time from 2-3 days to 2-3 hours. In the switch cabinet, file cabinets, elevators, security doors and other processing is well applied.
Press stamping integrated application
There are two main methods for the integrated application of robots and presses. First, a single robot punches up and down the material: the robot moves the material from the demolition platform to the positioning table, and then moves it to the press mold to perform pressing after positioning. After the stamping is completed, the robot picks up the material and puts it into the stacking table. A single press robot automatically loads and unloads material. The second is the robot stamping connection: through multiple robots, a stamping connection is established between multiple presses. According to the requirements of the forming process of the workpiece, multiple presses are required to be processed. The entire production line is composed of a demolition robot, a feeding robot, a transfer robot between presses, and a tail line robot. Compared with robots with linear coordinates, the use of industrial robots is more flexible, there is no contour requirement for the mold, and it is easy to integrate. Eston seamlessly connects its own press control system to the robot control system to achieve optimal coordination of the robot's movements and presses, and the use of fieldbus to maximize the efficiency of the entire production line and increase safety.
Hot Die Forging Integrated Application
Hot die forging production lines usually consist of two die forging presses, one for stamping and the other for trimming. The hot die forging robot integrated application usually configures two robots, one is responsible for transferring the high-temperature material processed by the intermediate frequency furnace to the press forming die forging press, and the other is responsible for taking the material from the press forming die forging press and transferring it to another die. Forging machine for trimming. In order to prevent high-temperature stamping of the workpiece from sticking to the mold, it is necessary to lubricate the mold with graphite after each stamping. Lubrication can be performed by robots or by special agencies. Due to the high temperature and humidity, and the harsh environment brought by graphite lubrication, special attention should be paid to the robot's protection work and the robot's own ability to resist heat radiation. Eston's robot 4-5-6 axis motor is in the robot arm and small The arm joints have the structural features of self-heat radiation. The electronic cam control system is installed in the forging press to coordinate the operation of the forging press and the operation of the robot to improve the processing efficiency and enhance the safety of the system.
Welding application
Welding is the process after the forming of the machine tool plate. There are two types of resistance welding and arc welding for robot welding. The application of welding robot accounts for more than 40% of the entire robot application. Arc welding application is based on the robot, configuration welding machine, wire feeder, welding gun, fixtures and other components composed of welding workstations. Eston offers 6kg dedicated arc welding robot workstations with arm lengths of 1400, 1600 and 2000mm. Resistance welding application is based on the robot as the core, configuration spot welding gun, welding controller, water and gas unit, pipeline package, fixtures and other components composed of welding workstations. Eston offers a 220kg special resistance welding robot workstation with an arm length of 2600mm. In addition, Estonia Automation develops a special welding software package for welding applications and integrates a welding expert process parameter library into a robot system to meet various types of needs.
Robots are typical representatives of advanced manufacturing technologies and automation equipment. Intelligent industrial equipment has become the basis for the upgrade and transformation of global manufacturing. The integration of industrial robots and CNC machine tools has enabled smart manufacturing and digital workshops and smart factories to move from concept to reality.
