Metal spinning, the spinning process is usually to clamp the metal sheet on the spinning machine. The spinning machine is similar to the ordinary machine tool. During the processing, the blank is formed against a three-dimensional mold core.
The spindle drives the blank and the mold core to rotate, the vertical spinning equipment, and then the rotary wheel is used to apply pressure to the rotating blank. Due to the rotary motion of the main shaft of the spinning machine and the longitudinal and transverse feed motion of the tool, this local plastic deformation gradually expands to the entire blank, thereby obtaining various shapes of hollow rotating body parts. Metal spinning is mostly used to form open-shaped workpieces, that is, the diameter of the forming end is larger than the diameter of the other parts, which allows the spun part to be removed from the core.
No matter which control method is used in CNC spinning, the determination and output of the wheel pass depends to a large extent on the operator’s skilled skills. Therefore, NC automatic programming technology will be an important research topic in the future. Only the shape of the workpiece should be input, and the program will automatically input the spinning tool path, the shape, size of the workpiece and the shape of the rotary wheel. Can spin out qualified products, the application of CNC technology in the spinning machine can achieve the following effects to a certain extent, that is, shorten the preparation time and processing time, adapt to changes in processing conditions, repeat the processing accuracy and prevent accidents. Not yet.
With the increase in the amount of sheet metal spinning, the application of spinning machines has become more and more extensive, and the equipment level of spinning machines has been continuously developed. CNC automatic spinning machines have become the main form of spinning machines. CNC automatic spinning machines started in the 1960s, when there were only simple CNC automatic spinning machines controlled by CNC belts and machine tool controllers. With the development of computer control technology, spinning equipment manufacturers, CNC automatic spinning machines and CNC machine tools have developed rapidly. The advancement of control technology has led to a significant improvement in the structure of spinning machines, and various forms of CNC automatic spinning machines have appeared.
No matter what control mode is used in CNC spinning, the wheel identification and loss of time depends to a large extent on the skill of the operator. Therefore, CNC automatic programming technology will be an important research topic in the future, as long as the input workpiece shape is completed, the program automatically enters the rotary tool path, the workpiece shape, size and shape of the wheel can be determined and input, and the wheel can pass qualified products, spinning Wire machine, the application of numerical control technology to a certain extent, the following results can be obtained, that is, shorten the preparation time and processing time, spinning equipment, can adapt to changes in processing conditions, processing accuracy and repeatability and so on.
With the increase of CNC spinning processing capacity of sheet metal spinning, the application of spinning machines has become more and more extensive, and the level of spinning machine equipment has continued to develop. CNC spinning machines have become the main form of spinning machines. CNC spinning began in the 1960s, with only simple CNC spinning with a control machine controller. With the development of computer control technology, CNC spinning and CNC machine tools have developed rapidly. Control technology has led to various forms of spinning machine structure and CNC spinning.
If a closed-shaped workpiece is desired, the workpiece needs to be spin-formed in pieces and then welded together to form the desired shape. Ideal spin forming materials include aluminum, copper, brass, bronze, silver and mild steel. The workpiece should be annealed before spinning. If the workpiece is to be greatly deformed during the machining process, two or three annealing treatments may be required before the end of spinning. Metal spinning is usually carried out under computer numerical control, which is also called CNC spinning.
The company has a spinning laboratory, an electromechanical-hydraulic integration technology laboratory, a mechanical performance laboratory, an ultrasonic/magnetic particle inspection room, a heat treatment production line, and a gas cylinder production line, which can develop, research and verify the spinning process and pressure vessel manufacturing process.
