The steel pipe expanding machine consists of the following components: hydraulic pushing machine host, automatic loading and unloading mechanism, hydraulic pump station, pipe alignment device, operating platform, motor control cabinet, intermediate frequency power supply, compensation capacitor, water cable, intermediate frequency coil adjustment frame, reactor.
The steel pipe expanding machine is used for the hot expanding production of seamless steel pipes, straight seam welded pipes, coiled pipes, and other steel pipes. The varieties of expandable steel pipes include various types of plain carbon steel, alloy steel, stainless steel, etc. The hydraulic expansion machine is suitable for forming and processing the pipe openings of copper pipes, aluminum pipes, and steel pipes.
The steel pipe expanding machine belongs to the straight seam metal welded pipe shaping equipment. It uses a conical expanding head to expand inside the steel pipe, eliminating the forming pressure and welding stress of the steel pipe, and ensuring the true diameter of the entire length of the straight seam welded steel pipe. The equipment is composed of a small car, an expander, a working sleeve, a fixed seat, an oil cylinder, a lubrication station, a bench, a hydraulic station, and an electrical control system. The expander is set on the small car, and the expander is connected to the oil cylinder by the working sleeve. The expander is composed of an expanding head, an expanding block, a guide plate, a pull rod, etc. The segmented mechanical extrusion process ensures the external diameter of the straight seam metal welded pipe and eliminates stress as a large-scale equipment
The steel pipe expanding machine is designed for insufficient production and incomplete specifications of large-diameter seamless steel pipes. The equipment is a dual cylinder or four cylinder parallel uniform speed pushing machine, and the pump station valve platform adopts an integrated form. Set the power of the intermediate frequency heating power supply, the thrust and stroke of the oil cylinder according to the outer diameter and length of the expanded steel pipe.
