cnc pipe end forming machine can automatically complete the pipe forming work when the specific working procedure is complete, which brings more convenience to the pipe bending work, saves the human resources in the working process, and reduces the risk brought by the operation process. The automatic management control can also smoothly complete the pipe bending work. The pipe bending machine will have heat in the long work, for which we have dealt with the overheating phenomenon, mainly by cooling, so the cold pair is really so important?

Timely cooling can make the tube billet under the bending part of the cooling medium can be rapidly cooled, resulting in the tube billet inner fold has not formed cooling, which can effectively prevent the tube billet inner wall of the fold when bending. The cooling system is mainly divided into two forms, one is the water cooling system, used in bending carbon steel pipe, low alloy steel pipe; The other is an air cooling system, which is applied to bending stainless steel pipes. The water used in the water cooling system is all softened water, and the softened water system is the equipment to control the quality of the cooling water. The use of softened water is conducive to extending the service life of the equipment.

In the field of automation, rotary encoders are sensors used to detect displacement, Angle, speed and acceleration. It relies on the control of indica rod, gear, measuring wheel or rope to convert the Angle quantity input to the shaft into the corresponding electrical pulse or digital quantity by the principle of rotation conversion. It has the advantages of small volume, high precision, reliable operation and digital interface. Encoders convert actual mechanical parameter values into electrical signals that can be processed by counters, tachometers, PLCS and industrial PCS.

Encoders are widely used in CNC machine tools, rotary tables, gear drives, robots, radar, military target determination and other devices and equipment that need to detect angles. Rotary encoder is a kind of sensor with many applications at present, which is composed of grating disk and photoelectric detection device. The grating disk is a certain diameter of the circular plate on the opening of a number of equal rectangular holes. Because the rotating code plate is coaxial with the motor, when the motor is rotating, the grating plate rotates at the same speed as the motor, and several pulse signals are detected and output by the detection device composed of electronic components such as light-emitting diodes.
