| Shutdown process of pipe bender after use
When stopping the pipe bender, we need to operate according to the following process: If the operation of the pipe bender is abnormal, it should be immediately stopped for inspection, mediation and repair. Turn off the switch and cut off the power. Place the workpiece in the specified location after stopping.
Timely cooling of the bending machine can make the tube billet under the bending part can be cooled by the cooling medium, so that the inside of the tube billet fold has not formed, such as to prevent the inner wall of the tube billet from folding 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 cooling water. The use of softened water is conducive to extending the service life of the equipment.
PLCK control system is widely used in encoder of pipe bending machine, and the machine tool, rotary table, transmission mark measurement of pipe bending machine need to detect the Angle of the device and equipment. Rotary encoder is a kind of sensor with many applications at present, which is composed of photoelectric detection device. Because the rotating code plate is coaxial with the motor, when the motor rotates, the motor rotates at the same speed, and several pulse signals are detected and output by the detection device composed of electronic components such as the light emitting tube.
In the automatic area of the bending machine, the rotary encoder is a sensor used to detect displacement, Angle, speed and acceleration rate. It relies on the control of gears, measuring wheels or ropes, and converts the input Angle to the shaft into the corresponding electrical pulse or digital amount using the principle of rotation conversion. It has the advantages of small size, good precision, and digital interface.
The above describes what needs to be paid attention to when the pipe bender is shut down, as well as the service life of the pipe bender and the advantages of the pipe bender. If you do not understand, our company welcomes you to our company sightseeing consultation!
We need to use the skills of bending pipe processing in many mechanical manufacturing, so whether we have met it now? Now let's get to know each other simply from some aspects.
The large-diameter cold-formed pipe is a common pipe fitting in the construction of long-distance pipeline. It is made by the vertical hydraulic pipe bender according to the actual trend of the pipeline and the measured bending Angle. Into the 21st century, the construction of long-distance pipeline projects in China has developed rapidly, and China's landform is large and diverse, there are more mountains and hills along the pipeline, and less plains, and the demand for cold-formed pipes is quite large, but because many construction units lack experience in the production of cold-formed pipes, how to make high-quality cold-formed pipes is still in the exploration stage. As a manufacturer of pipe bending machine, in the development, test and application of pipe bending machine, we have conducted in-depth research and testing on how to guarantee the quality of cold bending pipe, analyzed the common defects of cold bending pipe and put forward control measures for everyone's advice.
Each cold bend is made through several bends. The steel pipe is placed on the bending machine, the bending machine applies bending torque to the steel pipe, so that the local steel pipe has an appropriate amount of deformation, forming a certain Angle, and reaching the bending purpose. The basic process is: the back end clamp the steel pipe, and then the fulcrum of the main oil cylinder of the front end of the lower die moves upward, so that the steel pipe bends and deforms along the middle of the upper die curve until the bending is made. In the process of bending pipe in Hangzhou, the deformation of steel pipe is generated on the upper die, which plays the role of fetal, and its curve is determined according to the critical value of plastic deformation of steel pipe with different specifications and different materials. Different steel pipes correspond to different upper dies.
According to the causes of folding, we control from two aspects: on the one hand, during the bending process, the inner tube can not be placed near the front fixture side, but should be placed near the lower die bending cylinder side, and the back of the inner tube is about 150mm beyond the back of the upper tire. At the same time, when holding the first 3 bends, the lift of the bending cylinder should not be too large, and the lift of the bending cylinder should gradually increase in the next step until the steel pipe is at a higher point in the upper tire arc, so that the steel pipe can be gently transitional in the bending process, and the steel pipe does not produce instability deformation. On the other hand, the inner tube is adjusted before the bending of the steel pipe. When trying to bend a tube, the inner tube must be in a self-locking position and the bending can be held after the inner wall of the steel pipe is supported. By taking the above measures, you can ensure that the pipe does not fold.
The five characteristics of the pipe bender: accepting the touch screen plus numerical control module, conversational operation, light and easy program setting. The structure of the bed is stable and not easy to deform. Each gear can set 16 bending angles, and the image can store 16 groups of files. Both slow positioning effect, stable bending Angle, repeated accuracy to ±0.1° error information displayed on the screen, to help the operator immediately eliminate.
When the transformer is running (including no-load), refrain from stopping the supply of cooling water, and the waterway should be smooth to prevent water from splashing on the transformer. The zigzagged pipe should be carefully mediated before zigzagging, so that the chuck base and the base of the feel ring are consistent, and the support wheel supporting the workpiece should be mediated at an appropriate height to make the workpiece smoothly feed and ensure that the zigzagged pipe and the straight section are in the same plane. Before operating the equipment, prepare the equipment and open the equipment according to the requirements of the intermediate frequency power supply and the intermediate frequency transformer gate, open the equipment cooling water, when the pipe is heated to the temperature that can be tortuous, and the temperature of the inner wall should be maintained at least above 910℃, but not higher than the allowable high heating temperature of the pipe, the main motor can be opened for tortuous operation. If it is not heated to tortuous temperature or the workpiece is not heated, refrain from opening the main motor. After the winding is completed, the heating is terminated, and before the clamp is loosened, the main motor is also restrained from opening for the reverse operation of turning the wall.
