The pump station of the pipe expander is composed of multiple stages. There are 2 working pumps for equipment of one to three specifications, and 1 working pump for equipment of four to seven specifications. The pipe expander is equipped with fast forward and fast back pumps.The pipe expander is a double-cylinder parallel and uniform propelling pipe expander and a push-making machine. The pump station adopts the form of integrated connection, which is easy to maintain.The oil tank of the pump station is divided into two parts: the main and the auxiliary oil tank. The auxiliary oil tank is designed for the cleaning of the filter. When cleaning the filter, the connecting valve of the main and the auxiliary oil tank is closed, the hydraulic oil of the auxiliary oil tank is released, and the oil inlet of the oil pump is disassembled.Take out the filter, use gasoline or diesel to filter clean, the original can be installed back.

The intermediate frequency power supply of the pipe expander is installed at the front end of the work, and the intermediate frequency induction coil is installed on the adjustment frame. The mould of the pipe expansion core head and the pipe expansion raw material are attached. The water pump and the intermediate frequency power supply are turned on and the intermediate frequency power is adjusted to heat the mould and the pipe.

Resonant intermediate frequency power supply can be controlled, intermediate frequency coil, compensation capacitor, reactor and other components need water cooling, back and forth pipe-expanding machine equipment into a pusher pusher and twice in two forms, secondary propulsion always interchanged schedule 10-12.6 meters, the feeding structure is interchanged upper right stacking machine, drive the wire rope, push pipe, steel wire wheel, reciprocating motion,Feed the round pipe to be expanded into the pipe expanding machine.

The power control part of the pipe expander is installed in the main control box. Travel switches are installed at both ends of the stroke of the pipe expander. When the stroke of the push plate is in place, the pipe expander will stop automatically.The actual stroke of the oil rod should be less than the large stroke of the oil rod, that is, the front and rear ends of the oil rod are left 30-50mm from the actual head position of the oil rod, so as to avoid the impact of the cylinder flange when the cylinder piston runs to both ends, and the damage of the pipe forming and expanding machine.The formation of the above tube expanding machine is the experience obtained after many years of manufacturing.Welcome the users who need to expand the pipe machine to inquire.

Pipe expanding machine can expand the type of steel pipe: seamless steel pipe, spiral welded pipe, straight seam welded pipe.Pipe varieties are: provide, alloy steel, stainless steel and so on.

Pipe-expanding machine automatic control of intermediate frequency power supply at the time of expanding production will steel tube heated to the required temperature and constant, effectively avoid the human factors caused by the steel tube under high temperature to produce the quality of steel pipe and the mould of scrapped, at the same time avoid the low temperature and the thermal expansion unit increased thrust rod or die fracture phenomenon, caused by factors so as to avoid material is not smooth.Compared with manual operation, the steel pipe is heated, which saves energy, simplifies the operation procedure and reduces the labor cost. It can make one operator at most monitor the normal production and expansion of multiple pipe expanding units at the same time.Each set of unit is equipped with two temperature measuring points for automatic temperature control.According to the preset heating temperature of different grades of steel tubes, the heating temperature of the steel tubes to be expanded can be selected and kept constant, and it can be displayed and recorded in real time, and the real time curve and historical curve of the heating parameters can be printed and saved.Provide guarantees for data traceability.

Pipe expanding machine is the main production technology of large diameter steel pipe at present.It has been widely used in military industry, power plant construction, aerospace industry and Marine industry equipment manufacturing industry, and has made a great contribution to the customer's steel pipe industry and energy construction.Pipe expanding machine equipment is used in the production of thermal expanding 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.Cold drawn seamless steel pipe refers to the seamless waste pipe or seamless finished pipe as raw material, by cold drawing (drawing) machine drawing processing, the outer diameter size has the corresponding mold, the size is relatively precise.(characterized by the reduction of the outer diameter) the production steps of the seamless pipe expanding machine: it is made by the punching machine after the pipe is worn out -- rolling -- tension reducing machine -- cooling -- straightening -- cutting head -- packing -- storage.(the state is continuous operation, size precision is general) thermal expansion is made of seamless steel pipe as raw material in the pipe expansion machine heated to a certain temperature, the inner hole to add the required size of the mandrer to promote, the original diameter of seamless steel pipe expanded.The equipment of the pipe expanding machine mainly consists of: machine base, main cylinder support plate (including main cylinder), movable push plate, front support plate, automatic feeding structure, discharging roller table, mold support, intermediate frequency coil adjusting frame (including intermediate frequency heating coil), intermediate frequency power supply, electrical control system, etc.
