| The development trend of pipe expanding machine
Tube expanding machine is a kind of equipment which is often used for hot expanding of steel tubes. It is designed for the large-diameter seamless steel tubes whose production and specifications cannot meet the demand of domestic and foreign market. The main power source of the tube expanding machine is double cylinder or four cylinder parallel equal-speed pushing machine. Pump station valve table adopts integrated form. According to the outer diameter and length of the required extension steel pipe, the power of the intermediate frequency heating power supply, the thrust and stroke of the cylinder are set.
The equipment of the pipe expanding machine is composed of hydraulic pushing machine main engine, automatic loading and unloading, hydraulic pump station, pipeline device, console, motor control cabinet, IF power supply, compensation capacitor, water cable, IF coil adjusting frame, reactor and other parts. One of the advantages of the hot forming tube expanding machine is the automatic constant temperature system, which can effectively avoid the scrap of steel pipe quality and mold, or low temperature leads to the fracture of tie rod and mold, avoid unstable factors.
The pipe expanding machine is mainly composed of pipe expanding, base, master cylinder support plate, master cylinder, movable push plate, front support plate, automatic feeding series, feeding roller, mold bracket, IF coil adjusting frame, IF power supply, electrical control system, etc.
Expanding machine in the process of expanding production, system control of intermediate frequency power supply will steel tube heated to the required temperature and constant, effectively avoid the steel pipe caused by excessive combustion (heat) scrap quality decline and die for steel tube, to avoid the temperature is too low to cause fracture of the tie rod or mould, avoiding the unstable factors in the process of operation. Compared with the artificially heated steel pipe, it is energy saving and sanitary, simplifies the operation procedure and reduces the labor cost.
Pipe expanding machine is a kind of pipe fitting equipment which is sewn with large diameter and equal wall thickness. Aogang pipe fitting equipment mainly produces pipe fitting equipment: pipe expanding machine, elbow machine, elbow machine, tee machine, press, groove machine, straightening machine, straight seam welding pipe production line and other pipe fitting equipment. The whole production line of the pipe fitting equipment, such as mold. If coil, electrical control system, heating furnace, swing, coil, mandrel, etc.
