Description
Technical field
The utility model relates to the two roller pressurizing unit of a kind of welded tube.
Background technology
A large amount of heat trnasfer can be produced in the welded tube processes such as argon arc welding, plasma weldering, Laser Welding, high-frequency resistance welding, high-frequency induction; pressurizing unit is overall near welding crush zone thermal source, and too high temperature usually can make compression roller, bearing, the mandrel life-span shortens greatly.General common welded tube is all directly at welding squeezing roller pressure device integral outer spraying cooling, ensures that compression roller, bearing, mandrel work in normal temperature range.
But, when welding can not spray metal tube (as the easy hardening crack of cooling water is met in stainless steel welded pipe, the welding of stainless steel clad welded carbon steel pipe, the calcium heart yearn of seamless calcium heart yearn meets water meeting vigorous reaction) of outer cooling water; Time in welding requirements pipe without oil and metal tube (as the Bundy tube) of water; When HFI welding metal compound wire or section bar, because internal impedance device (as seamless calcium heart yearn) cannot be installed in the pipe of weld zone, high-frequency induction magnetic field energy is then difficult to the V-type open region focusing on welded still pipe, causes magnetic field energy to leak in a large number; Owing to not adopting spraying cooling, after causing compression roller, bearing, mandrel to be heated, temperature is too high, and too high temperature usually can make compression roller, bearing, the mandrel life-span shortens greatly.
Utility model content
Technical problem to be solved in the utility model is: provide a kind of two roller pressurizing unit of welded tube with interior refrigerating function.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: the two roller pressurizing unit of a kind of welded tube, comprise base, base rotates and is provided with horizontal screw lead, two ends, horizontal screw lead left and right are provided with the contrary screw thread of rotation direction, left sliding shoe is provided with by thread bush on the left of leading screw, right sliding shoe is provided with by thread bush on the right side of leading screw, left sliding shoe and right sliding shoe are vertically provided with pressurizing unit respectively, described pressurizing unit comprises the roller core shaft vertically arranged, roller core shaft is rotated by bearing and is provided with the pressure roller closed with the welded tube matching size of required extruding, cooling passage is provided with in roller core shaft, roller core shaft is respectively equipped with liquid inlet joint and fluid joint in the two-port of cooling passage.
As the preferred scheme of one, described left sliding shoe is provided with installing hole, and installing hole left end is embedded with left adapter sleeve, and be provided with in the middle part of left adapter sleeve and installing hole screwed hole in the same way, described leading screw is located in the screwed hole of left adapter sleeve; Described right sliding shoe is provided with installing hole, and installing hole right-hand member is embedded with right adapter sleeve, and be provided with in the middle part of right adapter sleeve and installing hole screwed hole in the same way, described leading screw is located in the screwed hole of right adapter sleeve.
As the preferred scheme of one, described base is provided with threaded adjusting bore, is equipped with regulating sleeve in threaded adjusting bore, and described leading screw one end is rotated by bearing and is located in regulating sleeve.
The beneficial effects of the utility model are: owing to being provided with cooling passage in roller core shaft, roller core shaft is respectively equipped with liquid inlet joint and fluid joint in the two-port of cooling passage, when pressurizing unit works, cooling liquid can be led in cooling passage, pressure roller, bearing, roller core shaft are cooled, thus extends the service life of whole device.
Because described left sliding shoe is provided with installing hole, installing hole left end is embedded with left adapter sleeve, and be provided with in the middle part of left adapter sleeve and installing hole screwed hole in the same way, described leading screw is located in the screwed hole of left adapter sleeve; Described right sliding shoe is provided with installing hole, and installing hole right-hand member is embedded with right adapter sleeve, and be provided with in the middle part of right adapter sleeve and installing hole screwed hole in the same way, described leading screw is located in the screwed hole of right adapter sleeve, decreases processing and the installation difficulty of this device.
