Description
Technical field
The present invention relates to the production line and the manufacture method of metal tube, be specifically related to a kind of production line and manufacture method of flat metal tube.
Background technology
What commercialization that air conditioner refrigerating (HVAC) uses and dwelling house used traditionally with heat exchanger is bronzing pipe or the efficient riffled tube and the external finned tube of circle, and the heat transference efficiency of this design is subject to the ability that finned tube conducts heat to air-flow.In recent years, the air conditioning for automobiles industry generally adopted porous metals flat tube (harmonica-shaped tube) to make condenser, and comparatively speaking the heat exchanger made from traditional pipe and external finned tube is characterized in higher heat conductive efficiency, littler volume.
The porous metals flat tube is generally the reasonable copper of heat transfer property, copper alloy, aluminum or aluminum alloy, generally adopt continuous extrausion process (Conform extrusion) manufacturing, prior art generally adopts following processing step: Metal Melting → casting → coil → anneal → unwrapping wire → aligning → surface clean → dry up → continuously extruded → cool off → dry up → coil.
Under prior art, after alloy casting becomes the bar base, generally pass through the rolling of some passages, after the metallic rod that obtains being convenient to push by the controlled rolling deflection, the metallic rod dish be become extruder need the drum of length.Through multi-pass rolled metal bar, its intensity may surpass the maximum tensile strength requirement that continuous extruder (Conform extruder) allows base line bar, therefore sometimes metallic rod being carried out homogenizing annealing handles, to reduce intensity, improve plasticity, adopt special unwrapping wire equipment that the metal drum is supplied to continuous extruder stably then.The major defect of prior art is exactly that flat metal tube can not be produced continuously, when becoming drum and unwrapping wire, the metallic rod dish all to use special equipment, therefore increased the operating cost of enterprise, as cost of equipment and labour cost, and metallic rod has also increased the danger of damage through in the process of these operations.
Continuously extruded for flat metal tube, material therefor is mainly based on non-ferrous metal or its alloys such as copper, aluminium, intensity is lower, and because the heat transfer property of flat metal tube is had higher requirement, flat metal tube constantly develops towards the direction of thickness less than the stephanoporate thin wallization of 5mm, therefore in extrusion process, the state of tension instability may cause the flat metal tube performance to change.For example, when the excessive velocities of metallic rod, the phenomenon of clot can occur, the speed of metallic rod is slow excessively, can be subjected to bigger pulling force, very person's fracture of plastic deformation may take place in metallic rod, during extruding; various defectives may appear in the thin-walled place, and in the time of serious, may breaks in production.Because mechanically operated error, prior art can't satisfy the steady and continuous supply of milling train to the flat metal tube extruder, can only adopt special unwrapping wire equipment to guarantee continous-stable supply to the flat metal tube extruder, can't realize the continuous production of flat metal tube, this greatly reduces the production efficiency of enterprise.
In modern rolling steel industry, various bars, sheet material will be through the technique for continuous rolling of tens passages, and the transmission system unification of every milling train is controlled by rolling system, and rolling system is made up of microprocessor, transmission system, communication system.Before the per pass rolling process or accurate tension measuring device is all arranged afterwards, the variation of measuring steel plate or rod iron, rolling system is coordinated the length velocity relation of each frame of tandem rolling unit by the variation of this tension force, dynamically satisfies metal mass flow and equates.But this control system is for the continuous manufacturing of flat metal tube, be inappropriate, because before adjusting rolling mill speed, metallic rod tension force changes, the strength of materials such as steel plate, rod iron height can not be subjected to seriously influencing very much, and the continuous extruder target mainly is non-ferrous metal or its alloy, intensity is lower, so the variation meeting of tension force comparatively seriously influences its performance generation.
