Four major applications of stamping manipulator in metal forming machine tools

In the past, only the automotive industry has been the most important field of stamping manipulator application, with the improvement of automation demand, the application of industrial stamping manipulator has been greatly expanded, in addition to the traditional welding application, stamping manipulator has been widely used in machine tool loading and unloading, material handling and palletizing, grinding, spraying, assembly and other fields. Metal forming machine tool is an important part of machine tools, forming processing is usually associated with high labor intensity, noise pollution, metal dust, etc., sometimes 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 stamping manipulator and forming machine tool can not only solve the problem of enterprise employment, but also improve processing efficiency and safety, improve processing accuracy, and have a lot of room for development.

CNC bending machine integrated application

There are two main ways to integrate the bending application of the stamping manipulator. First, with the bending machine as the center, the stamping manipulator is equipped with a vacuum suction cup, and the magnetic tension loading rack, positioning table, unloading table, and turning frame form a bending unit. The second is the flexible processing line of plate formed by stamping manipulator and laser equipment or CNC turntable punch, industrial stamping manipulator walking shaft, sheet material transmission line, positioning table, and vacuum suction cup gripper. It is the first to use its own technology and platform in the stamping manipulator control system and the machine tool numerical control system to achieve seamless connection, develop a bending software package, and realize closed-loop control of the stamping manipulator material support during the bending process. At different bending speeds, the stamping robot achieves full tracking with automatic matching, and the bending software package also reduces the bending teach-in time from 2-3 days to 2-3 hours. It has been well used in the processing of switch cabinets, filing cabinets, elevators, anti-theft doors, etc.

Integrated press stamping applications

There are two main ways to integrate the stamping manipulator with the press. First, a single stamping manipulator stamping loading and unloading: the sheet material is transferred from the destacking table to the positioning table through the stamping manipulator, and then transferred to the press die to implement stamping after positioning, and after the stamping is completed, the material is taken and put into the stacking table by the stamping manipulator, so as to realize the automatic loading and unloading of the stamping manipulator of a single press. The second is the stamping connection of the stamping manipulator: the stamping connection is established between multiple presses through multiple stamping manipulators. According to the requirements of the processing workpiece forming process, it is necessary to cooperate with multiple presses for processing, and the whole production line is composed of a destacking stamping manipulator, a feeding stamping manipulator, a press and a transfer and handling stamping manipulator, and a tail line stamping manipulator. Compared with the manipulator with linear coordinates, the industrial stamping manipulator is more flexible, has no high requirements for the mold, and is easy to integrate. It is the first to use the seamless connection between the autonomous press control system and the stamping manipulator control system, so that the action of the stamping manipulator and the press can be optimally coordinated, and the fieldbus is used to maximize the efficiency and safety of the entire production line.

Hot die forging integrated applications

A hot die forging production line usually consists of two die forging presses, one for stamping and the other for trimming. The integrated application of hot die forging and stamping manipulator is usually equipped with two stamping manipulators, one is responsible for transferring the high-temperature materials processed by the intermediate frequency furnace to the stamping and forming die forging press, and the other is responsible for taking the material from the stamping and forming die forging press and transferring it to another die forging press for trimming. In order to prevent the high-temperature stamping workpiece from sticking to the die, it is necessary to lubricate the die with graphite after each stamping, and the lubrication can be completed by the stamping manipulator or by a special mechanism. Because forging is a harsh environment brought by high temperature and high humidity and graphite lubrication, special attention should be paid to the protection of the stamping manipulator and the ability of the stamping manipulator itself to resist thermal 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 stamping manipulator, improve the processing efficiency and improve the safety of the system.

Welding applications

Welding is the post-processing process of forming machine tool plates, and there are two types of stamping manipulator welding: resistance welding and arc welding, and the application of welding stamping manipulator accounts for more than 40% of the entire stamping manipulator application. The application of arc welding is based on the stamping manipulator as the core, and the welding workstation is composed of welding machine, wire feeder, welding gun, tooling fixture, etc. It is the first to provide special arc welding stamping manipulator equipment with 6kg and arm lengths of 1400, 1600 and 2000mm. The application of resistance welding is based on the stamping manipulator as the core, and the spot welding workstation is composed of spot welding guns, welding controllers, water and gas units, line packs, tooling fixtures, etc. It is the first to provide a special resistance welding stamping manipulator workstation with 220kg and an arm length of 2600mm. In addition, Capital Automation has developed a dedicated welding software package for welding applications, integrating a library of welding expert process parameters into a stamping manipulator system to meet various types of needs.

Stamping manipulator is a typical representative of advanced manufacturing technology and automation equipment, and intelligent industrial equipment has become the basis for the upgrading and transformation of the global manufacturing industry. The integrated application of industrial stamping manipulator and CNC machine tool makes intelligent manufacturing, digital workshop, and intelligent factory move from concept to reality.
