| How to choose the pipe expanding machine when selecting the detailed introduction of the pipe expanding machine
Pipe expanding machine is designed for large diameter seamless steel pipe with insufficient production capacity and incomplete specifications.The pipe expander is made of double oil cylinders or four oil cylinders with parallel and even speed, and the valve stand of the pump station of the pipe expander adopts the integrated form.According to the outer diameter and length of the expanded steel pipe, the power of the medium frequency heating power supply, the thrust and stroke of the cylinder are set.The pipe expander is composed of the following parts: the hydraulic push machine, the automatic feeding mechanism, the hydraulic pump station, the medium frequency power supply, the medium frequency coil adjusting frame, the above are the main parts of the pipe expander.The company can be customized according to customer requirements of automatic pipe expansion machine, the company's customized pipe expansion machine has obtained the national patent.The production range of the pipe expanding machine is 60-1420, the thickness is 3-120, the material that the pipe expanding machine can produce is carbon steel, alloy steel, stainless steel and so on.All the purchase of our company's products our company can be delivered in about 2 months.
Operation process and composition of pipe expanding machine
Operation process of the expanding machine: the flushing pipe is sent to the rotary roller device on the center line of the expanding machine.Using this rotary idler, in combination with the camera system, the pipe weld is rotated precisely to the 12 o 'clock position to ensure that the weld will be able to enter the groove in the upper sector of the tool during subsequent expansion.The lifting cone roller table lifts the pipe to the centerline of the expanding machine, and the position is controlled by the displacement sensor in the lifting hydraulic cylinder.The clamping trolley moves forward and is controlled by the metal detector to detect the end of the tube and is stuck. At the same time, a signal is sent to start the feeding roller of the clamping trolley, and the position is controlled by the encoder. During the moving process, the metal detector at the expanding head is set to detect the front end of the tube, so as to measure the position of the pipe.The length of the pipe is combined with the expanding head to automatically calculate the optimal number of expanding steps.The jaws of the clamp can be rotated to avoid damaging the pipe wall.In the forward process, the height of the clamp can be adjusted to compensate for the deviation of the straightness of the pipe and optimize the straightening effect of the expanding machine.
The pipe expanding machine mainly includes: the frame, the main cylinder support plate, the movable push plate, the front support plate, the automatic feeding mechanism, the feeding roller table, the mold support, the intermediate frequency coil adjusting frame, the intermediate frequency power supply (including the intermediate frequency heating coil), and the electrical control system.
