The advantages of tube expanding machine and intelligent constant temperature system

Pipe-expanding machine intelligent control medium 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 steel pipe under the high temperature of steel pipe quality and mold scrapped, and to avoid the low temperature and the thermal expansion unit increased thrust rod or die fracture phenomenon, caused by eliminating the unsafe factors.Compared with manual operation, it can heat the steel pipe, save energy and protect the environment, simplify the operation procedure, reduce the labor cost, and make it possible for one operator to monitor more than one tube expanding unit at the same time for normal production and expansion.Each unit is equipped with two temperature measuring points for intelligent 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 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.

Working principle of intermediate frequency expanding machine: raw materials will be prepared steel pipe set in the expansion pipe mould core head, medium frequency induction heating coil in the raw material of steel pipe end and expanding mold core head, fixed expansion pipe mould core head tie rod end, open the cooling water pump, open the medium frequency power supply, the raw material heated to a certain temperature and flaring die for steel tube, expanding opening pipe-expanding machine can start pushing system.

It is composed of rotating roller device, lifting roller table, rotating tie rod sleeve supporting rod, clamping tube trolley, expanding head, tie rod sleeve, hydraulic cylinder and frame of the expanding machine.The mechanical pipe expander is also a head and diameter expanding machine, which expands and expands the straight seam submerged arc welded pipe step by step, and has obtained the roundness, straightness and inch accuracy required by the standard technology.

The medium frequency pipe expander can not only expand the steel pipe, but also expand the end of the steel pipe.This is the company's production of medium frequency pipe expanding machine also known as the expanding machine and expanding head machine.

Intermediate frequency expanding machine is 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 various industries, power station construction, aerospace industry and Marine industry equipment manufacturing, and has made a great contribution to the national steel pipe industry and energy construction.

The medium frequency pipe expanding machine can enlarge the inner diameter of the steel pipe and expand the other end of the steel pipe, which is also called the end expanding machine.With the continuous improvement of the quality of the thermal expanding steel pipe by users, our factory has developed an intelligent constant temperature system of the domestic pipe expanding machine for this equipment, which ensures the product quality of the thermal expanding steel pipe to the maximum extent.

Medium frequency pipe expanding machine is used in the production of thermal diameter of seamless steel pipe, straight seam welded pipe, coil pipe and so on.Can expand the steel pipe varieties are: carbon steel, alloy steel, stainless steel and so on.

Composition of medium frequency pipe expander: base, main oil cylinder, movable push plate, front support plate, automatic feeding mechanism, feeding roller table, mold bracket, medium frequency coil, medium frequency heating coil, medium frequency power supply, electrical control system.
