Description
Technical field
The present invention relates to geothermal heating system current divider processing technique fields, and in particular to a kind of end of geothermal heating system current divider
Processing technology.
Background technology
Floor heating point, water collector (manifold) be in water system, is supplied for connecting each road heating tube, return water matches, catchments
Device presses in return water and is divided into water knockout drum, water collector, so referred to as water collecting and diversifying device or condensate correcting-distribuing device, is commonly called as water knockout drum or current divider.
Current divider is geothermal heating system part flow arrangement important component.
The current divider to circulate currently on the market is all to encircle fashion of extrusion processing using hydraulic press surrounding, the disadvantage is that tube body table
There is several folds and non-thickened wall in face and inside, and the interior outside that needs to polish makes its bright and clean beauty, and tube body is thinning after polishing, only
It can shallow processing inside thread.And to ensure that endurance of the screw thread to hydraulic pressure, tube body cannot polish too much, tend not to beat completely
It polishes fold and influences beauty.
Invention content
Present invention aim to address disadvantages described above, provide a kind of end processing technology of geothermal heating system current divider.
The present invention provides a kind of end processing technology of geothermal heating system current divider, and procedure of processing includes：
The electrothermal furnace that tube body is 180 DEG C~250 DEG C in temperature is stood 10~20 minutes, stablizes tubular body by the first step
Molecular structure；
Second step is continuously up and down reciprocatingly acted at least five times by punching machine using different special necking dies, squeeze plus
Work, friction generate high temperature, and tube wall makes its internal original molecular structure be shifted inwardly with top, reach tube wall because high temperature softens
The purpose thickened；
Third walks, and round is processed into the end at tube body both ends, also, the end after processing passes through circular arc with former square tube
Connection；
4th step, the inner end portion at tube body both ends process screw thread respectively.
In second step, use successively
WithMold to the both ends of tube body, continuously up and down reciprocatingly acted for eight times by punching machine, extrusion process.
After 4th step, by machining, the opening at the both ends of the tube body is processed into required special shape.
Temperature in the electrothermal furnace is controlled at 190 DEG C~220 DEG C.
Temperature in the electrothermal furnace is controlled at 200 DEG C~210 DEG C.
The tube body uses appearance and size for 304 stainless steel tubes of 41mm*39mm, wall thickness 1.6mm.
After third step, the wall thickness of the end at the tube body both ends is 1.6mm~2mm.
After third step, the wall thickness of the end at the tube body both ends is 1.85mm~2mm.
The tube body is rectangular tube body or special-shaped tube body.
Beneficial effects of the present invention：The present invention makes its fever change pipe wall material by compressional movement above and below special die
Original molecules align mode, extrusion process, friction generate high temperature, tube wall because high temperature softens, make its internal original molecular structure to
Inside and top transfer, achieve the purpose that tube wall thickening, since the end lower of tube body will not by friction and Extrusion material molecule
Transfer downwards.Therefore, the both ends for the current divider that processing technology using the present invention makes are circle, tube wall thickening and outer sightseeing
It is clean.
