Robots in the four major applications of metal forming machine tools

In recent years, robots have become hot, and the automotive industry has been the most important field of robot applications in the past. However, with the continuous expansion of robot applications, robots have been widely used, especially in the application of metal forming machine tools. Look at the four applications of robots in metal forming machines.

In the past, the automotive industry has been the most important field of robotic applications. With the increase of automation requirements, industrial robot applications have been expanded. In addition to traditional welding applications, robots load and unload materials, palletizing, grinding, spraying, and assembly. Other fields have also been widely used. Metal forming machine tools are an important part of machine tool 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 the enterprise is difficult to recruit. The integration of industrial robots and forming machine tools not only solves the problem of enterprise users, but also improves processing efficiency and safety, and improves machining accuracy, which has great room for development.

CNC bending machine integrated application

There are two main ways to integrate robot bending applications. First, the bending machine is centered on the robot, and the robot is equipped with a vacuum suction cup, and the magnetic separation sheet loading frame, the positioning table, the feeding table and the turning frame form a bending unit. The second is the flexible processing line of the plate formed by the robot and the laser equipment or the CNC rotary table punching machine, the industrial robot walking shaft, the sheet conveying line, the positioning table and the vacuum suction cup gripper. Eston uses his technology and platform of robot control system and machine tool numerical control system to realize seamless connection and develop bending software package to realize closed-loop control of robot material during bending process. At different bending speeds, the robot achieves full tracking of automatic matching, and the bending software package also shortens the bending teaching time from 2-3 days to 2-3 hours. It is well used in the processing of switch cabinets, file cabinets, elevators, security doors and so on.

Press stamping integrated application

There are two main ways to integrate robot and press stamping applications. First, a single robot punching and unloading: the sheet is transferred from the unloading station to the positioning table by the robot, and then moved to the press mold for positioning and punching. After the punching is finished, the robot takes the material into the stacking table to realize A single press robot automatically loads and unloads. The second is the robotic press connection: through multiple robots to establish a stamping connection between multiple presses. According to the requirements of the forming process of the workpiece, it is necessary to cooperate with multiple presses. The whole production line consists of a demolition robot, a loading robot, a transfer robot between the presses, and a tail robot. Compared with robots with linear coordinates, industrial robots are more flexible, have no equal height requirements for molds, and are easy to integrate. Eston uses the independent press control system and the robot control system to seamlessly connect, so that the robot's action and press are optimally coordinated. The field bus is used to maximize the efficiency of the entire line and provide greater safety.

Hot forging integrated application

Hot forging lines are usually composed of two die forging presses, one for punching and the other for trimming. The hot forging robot integrated application is usually equipped with two robots, one is responsible for transferring the high temperature material processed by the intermediate frequency furnace to the stamping die forging press, and the other is responsible for transferring the material from the stamping die forging press to another die. The forging press performs trimming. In order to prevent the high-temperature stamping workpiece from sticking to the mold, it is necessary to perform graphite lubrication on the mold after each pressing, and the lubrication can be completed by the robot or by a special mechanism. Because forging is a harsh environment caused by high temperature and high humidity and graphite lubrication, pay special attention to the protection work of the robot and the ability of the robot itself to resist heat radiation. The Eston Robot 4-5-6 axis motor is in the robot boom and small The arm joint has a structural feature of self-distance from heat radiation. 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 to improve the processing efficiency and improve the safety of the system.

Welding application

Welding is the post-processing of forming machine tool plates. Robot welding has two types of resistance welding and arc welding. Welding robot applications account for more than 40% of the entire robot application. The arc welding application is based on the robot, and is equipped with welding stations, wire feeders, welding guns, fixtures and other welding stations. Eston offers 6kg dedicated arc welding robotic workstations with arm lengths of 1400, 1600 and 2000mm. The electric resistance welding application is based on the robot, and is equipped with a spot welding station composed of a spot welding gun, a welding controller , a water gas unit, a pipeline package, and a fixture. Eston offers a 220kg, 2600mm arm dedicated resistance welding robot workstation. In addition, Eston Automation 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 global manufacturing. The integration of industrial robots and CNC machine tools enables intelligent manufacturing and digital workshops and smart factories to move from concept to reality.

Electric Hydrofoil Propulsion System is a powerful Underwater Jet System, Application to hydrofoil , surfboard,small fishing boats ,Even you can use it for diving booster.  Our Electric hyrdofoil propulsion system is a Tunnel Jet type propulsion system. With the protective shield  on both side, these type design can keep the propeller safe ,avoid Accidental inhalation of the grass, fishes. High efficiency brushless motor with the propeller get the lower working current and long continuouse working time. This is quite different of our proulsion system to compare with other oridinary tunnel jet systems. We use the boat ESC as the controller ,and it is only 150A , we controled  our tunnel jet engin working with lowercurrent .reduce the cost and improve the system life. economy for maintenance and repair.The system shell made by Aluminium Alloy 6061,light weight, small size but powerfull thrust.
