The composition and process flow of pipe expanding machine

The composition and process flow of pipe expanding machine

The pipe expanding machine is mainly divided into the following components: hydraulic pipe expanding machine host, automatic up and down material structure, hydraulic pump station, pipeline device, console, motor control cabinet, IF power supply, compensation capacitor, water cable, IF coil regulating frame, reactor. The pipe expanding machine expands the pipe diameter of Φ1520mm and the wall thickness of 120mm.

Operation process of pipe expanding machine: send the washed pipe to the rotary roller device on the center line of the diameter expansion machine. A rotary roll device, combined with a camera system, rotates the weld to 12 o 'clock to ensure that the weld enters the upper sector slot of the diameter expansion tool during the subsequent diameter expansion process. The lift cone roller raises the pipe to the center line of the diameter tube expander and is controlled by a displacement sensor in the lift hydraulic cylinder. The clamp car moves forward, controlled by a metal detector, detects that the end of the tube is stuck, and sends a signal to start the feed roller of the clamp car, the position of which is controlled by the encoder. During driving, a metal detector is installed at the diameter expansion end to detect the front end of the tube to measure the position of the tube. In the process of pipe expanding production, the pipe length and diameter expanding machine automatically controls the medium frequency power supply, heating the steel pipe to the required temperature, keeping constant, effectively avoiding the steel pipe and die due to the temperature of the steel pipe is too high and avoid the pull rod or die due to the temperature is too low to increase the thrust of the thermal expansion machine. Combined with the head, the diameter expansion steps are automatically calculated. The clamp mouth of the pipe can be rotated to avoid damage to the pipe wall. Compensation pipe diameter deviation, optimize the straightening effect of diameter pipe expander.

Pipe expanding machine manufacturers mainly produce pipe expanding machine equipment that customers need according to the steel pipe that customers need to produce. When customers order pipe expander, we can clearly understand the different types of pipe expander and different production sizes and materials. According to the model provided by the customer, we will produce the pipe expander satisfactory to the customer within the time signed with the customer. The pipe expanding machine has the advantages of simple operation, high production efficiency and low cost.
