| Pipe expanding machine and pipe expanding machine are used to produce steel pipe
The expanding machine mainly has the expanding pipe mandrel, according to the customer needs to produce the caliber to customize the expanding pipe mold.The pipe expanding machine is mainly designed for the lack of production and specification of large diameter seamless steel pipe.The pipe expander is made of steel tubes with double or four cylinders 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 main machine, automatic loading and unloading mechanism, hydraulic pump station, intermediate frequency power supply, intermediate frequency coil adjusting frame, reactor and other components
Stroke and composition of pipe expanding machine
The total stroke of the pipe expanding machine is 10-14.5 meters. The loading and unloading mechanism of the pipe expanding machine adopts roller to drive the steel pipe forward to complete the feeding.The intermediate frequency power supply is installed at the front end of the pipe expander, and the intermediate frequency coil is placed on the intermediate frequency coil adjustment frame. The core die of the pipe expander is fixed, the original pipe is put in, the water pump and the intermediate frequency power supply are turned on, and the intermediate frequency power is adjusted to adjust the pipe core
Mold and tube heating.Then start the pipe making machine and you can officially expand the pipe.The intermediate frequency coil, compensating resonant capacitor, reactor and other components of the pipe expander need circulating water cooling.The electrical control part of the pipe expanding machine is installed in the electric control box. The travel switch is installed at both ends of the pipe expanding machine travel. After the push plate moves in place, it will stop automatically.
Special equipment for steel tube hot hole enlargement, mainly for domestic large diameter steel pipe production cannot meet the demand of market and all kinds of steel pipe specification is not complete, meet the needs of small batch more varieties of steel pipe production, can satisfy the different material steel pipe hole enlargement and various non-standard steel tube expanding needs, is currently the main production process of large diameter steel pipe.It has been widely used in military industry, power plant construction, aerospace industry and Marine industry equipment manufacturing, and has made a great contribution to the national steel pipe industry and energy construction.
The equipment is used in the production of thermal expansion of seamless steel pipe, straight seam welded pipe, coil pipe and so on.Can expand the variety of steel pipe: all kinds of carbon steel, alloy steel, stainless steel and so on.
The pipe expanding equipment mainly includes: machine base, main cylinder support plate (including main cylinder), movable push plate, front support plate, automatic feeding mechanism, discharging roller table, mold support, intermediate frequency coil adjusting frame (including intermediate frequency heating coil), intermediate frequency power supply, electrical control system, etc
