Summary of the invention
The object of the invention is in condenser pipe continuous flow procedure, to carry out continuous continual Welding Problems in order to solve, and in assurance welding process, avoid weld wheel sparking and effectively reduce the phenomenons such as flattening, pit, pinprick, providing a kind of dislocation type of reasonable in design to hang the pipe soldering oven of arc power transmission sheave group.
Above-mentioned technical problem of the present invention is mainly solved by following technical proposals: a kind of dislocation type is hung the pipe soldering oven of arc power transmission sheave group, comprise soldering casing, cooling water-supply-pipe, it is characterized in that being provided with two fast pulleys in described soldering casing, below two fast pulley middle parts, be provided with a weld wheel, described fast pulley and weld wheel are positioned at same plane, and form tube welding passage by the deep-slotted chip breaker on fast pulley and weld wheel circumference; Described weld wheel is assemblied on hollow contact rod, and cooling water-supply-pipe is connected with contact rod.Condenser pipe diameter is less, reasonable by the deep-slotted chip breaker guide-localization on weld wheel circumference, easily realizes tensioning, and welding position is not only stressed even, and the full equilibrium of fusion point.In soldering casing, temperature is higher, the maximum point that is heated is positioned in weld wheel and two fixed tires, fast pulley and weld wheel all adopt the good copper material of heat conduction, contact rod and fixedly wheel shaft adopt copper material equally, contact rod, be designed to hollow shaft because of fixed wheel axle, cooling water is introduced, weld wheel etc. is lowered the temperature rapidly.Weld wheel is positioned at the below, middle part of two fast pulleys, rather than direct and the upper and lower opposite joining relation of fast pulley, the location of welding pipe being exerted pressure downwards from both sides before and after weld wheel by two fast pulleys, due to fast pulley no power, can not strike sparks with welding pipe, and weld wheel always has the tension force making progress, even if there is the defects such as bending, hole point in welding pipe self, weld wheel also remains the close contact to welding pipe, make gapless between weld wheel and welding pipe, prevented spark phenomenon.
As preferably, described contact rod is arranged in bearing block, between contact rod and two fast pulley installation shaft, is provided with spacing adjusting device.Contact rod in a kind of rotation status, keeps welding pipe with less frictional force continuous welding reach in welding process.Distance between the adjustable weld wheel of spacing adjusting device and fast pulley, the also tension force of adjustable weld wheel to welding pipe.
As preferably, two described fast pulleys are arranged on respectively in hollow shaft separately, and cooling water-supply-pipe communicates with described hollow shaft one end.Hollow shaft is mainly used in communicating with cooling water, guarantees the efficiently radiates heat of fast pulley.
As preferably, the diameter of described cooling water-supply-pipe is less than hollow part diameter in contact rod, and it is inner that the water side of cooling water-supply-pipe is positioned at contact rod hollow part, and contact rod hollow part insert port place is provided with water recovery apparatus.Cooling water directly leads to the inner i.e. bottom of contact rod by water-supply-pipe, makes radiating effect reach best, and water after heat exchange from contact rod bottom, to be back to head be in time hollow part insert port.
As preferably, the described carbon brush configuration that is provided with coordinates with described contact rod, establishes carbon brush and hold out against spring in carbon brush configuration.Brush is the sliding-contact body of conductive electric current, and foreign current is added to by carbon brush on the contact rod of rotation, to weld wheel input current.Carbon brush holds out against spring and guarantees that carbon brush can not depart from contact rod within service life.
As preferably, described spacing adjusting device comprises adjusting support, regulates in support adjusting screw mandrel is housed, and regulates on screw mandrel stage clip is housed.Spacing adjusting device has two effects, and the one, regulate the distance between contact rod and two fast pulleys to adjust greatly, by regulating screw mandrel to complete; The 2nd, guarantee that all the time conductive casters has a tensile force to welding pipe, realizes by stage clip.
As preferably, described soldering casing is provided with hydrogen input device.Hydrogen, as reducing agent, plays the effect of reduction-oxidation layer in post annealing process.
As preferably, described cooling water-supply-pipe is positioned at contact rod insert port position and is provided with tube gripper.By tube gripper, cooling water pipe is inserted when the contact rod central space, do not contact with contact rod hollow wall, avoid sticking together in use procedure and affect the work such as dismounting grade of safeguarding.
As preferably, described pipe soldering oven, is characterized in that, is positioned at described soldering casing pipe entrance one end and is provided with electrode piece.Electric current leads to weld wheel by electrode piece.
Effective effect of the present invention is: two fast pulleys coordinate with a weld wheel dislocation, effectively avoid sending out the quality problems such as flattening, pit, pinprick; As continuous braze welding production line, pipe self requires greatly to reduce to the deep-slotted chip breaker of welding position and the pass that forms thereof; Even if pipe exists buckling phenomenon, during steel-pipe welding position, weld wheel can contact with pipe all the time, avoids sparking, occurs quality accident.
