In refrigerating field application widely, seamless internal thread copper pipe can be made air conditioner condensation to seamless internal thread copper pipe
Device, radiator etc., the helicitic texture of copper pipe inner surface are a significant increase the heat exchange surface area of copper pipe inwall, improve heat exchange
Efficiency.Internal thread machining in seamless internal thread copper pipe is generally processed shaping by the way of outer mold, inner mold combination,
Outer mold generally uses spinning machine, spinning machine to generally include clamper, some steel balls, and copper pipe is from the endoporus that steel ball is surrounded
Pass through, clamper extruding steel ball, whole spinning machine rotation, steel ball produces pressure to cause that copper pipe external diameter reduces copper pipe outside；
Inner mold generally includes travel core, core bar, screw thread core print composition, and thread groove, steel ball extruding copper are provided with above the circumference of screw thread core print
During pipe outer wall, copper pipe inwall extends to enter in thread groove and produces internal thread, whole copper pipe to be moved in the presence of haulage gear,
When copper pipe is moved, the screw thread being molded on copper pipe inwall can drive the rotation of screw thread core print, travel core and core bar when departing from screw thread core print
For screw thread core print axial limiting.Due to very big friction can be produced when the internal thread that copper pipe inwall is formed departs from screw thread core print
Power, the length of usual copper pipe reaches myriametre, the abrasion of screw thread core print is so easily lead to, in order to slow down the mill of screw thread core print
Damage, copper pipe is successfully continuously carried out drawing processing, usual copper pipe is before internal thread machining just as being poured into inside copper pipe
Substantial amounts of lubricating oil, it is ensured that copper pipe inwall lubricates.
But copper pipe is when actual internal thread machining, because copper pipe inwall first passes through travel core, then by screw thread core print,
When copper pipe inwall is by travel core, most lubricating oil on inwall is just wiped off by travel core, at screw thread core print
Lubrication oil content on copper pipe inwall is little, because main pipe can have a certain degree of bias in itself, although by floating core head
When completed a part of correction, along with the uneven state of copper pipe inwall oil film thickness, the processing of copper pipe inwall
Internal thread still can have that skewness, thread are high to be had differences, so as to influence copper tube heat exchange decreasing efficiency.
