Abstract
The invention provides a cooling pipeline aluminum branch pipe and a manufacturing method of the cooling pipeline aluminum branch pipe, and belongs to cooling system pipelines. An existing cooling pipeline branch pipe produced through stamping is poor in compressive strength and high in leakage rate. According to the method, a multi-way joint substrate is made of aluminum alloy profile produced through extrusion forming or aluminum alloy castings produced through pressure casting. When an output hole is machined, drilling is conducted through a drilling machine and a drill bit to machine out a basic hole firstly, then the drilling machine and a vertical milling cutter counter sinking are adopted to machine out a faucet part without replacing a clamping. When an input hole is machined, the lathe dog clamping drives a workpiece to rotate, drilling is conducted through the drill bit to machine out a basic hole, then the lathe and the vertical milling cutter counter sinking are adopted to machine out the faucet part without replacing the clamping. Counter sinking machining is conducted on the basic hole through a vertical milling cutter with the same diameter with the basic hole instead, the bottom of the basic hole is machined to be a flat bottom, boring processing is conducted on the input hole through a boring cutter, and medium circulation obstacle is removed. An input pipe and an output pipe are inserted into the input hole and the output hole and are fixed in a welding mode. According to the method, the multi-way joint substrate is high in strength and good in welding firmness, and the cutting machining hole is high in accuracy.
Description
Technical field
The invention belongs to refrigeration system pipeline technical field, especially relevant with a kind of refrigeration pipe aluminium branch pipe and manufacture method thereof.
Background technique
Refrigeration pipe branch pipe is in refrigeration pipe, for the input of Jiang Yi road medium, to be divided into the connecting pipeline of two-way and the output of above medium, and its structure is mainly to use threeway or multi-pass connecting joint connecting circular tube.The multiple-pass joint of existing branch pipe adopts copper pipe punching press to make, its manufacturing process is mainly uses the larger pipe of diameter, reducing is carried out as input hole in one end, make its internal diameter be slightly larger than supplying tube, the other end re-uses punch ram after using a plurality of cylinder mold interval to insert pipe inner chamber, after both sides tube wall between a plurality of cylinder mold is caved in and connect, form a plurality of holes suitable with cylinder mold diameter as delivery outlet, again input copper pipe and output copper pipe insertion input hole and delivery outlet are welded, solder flux infiltrates between pipe and hole wall, also penetrate into and connect the gap between tube wall simultaneously.Because such branch pipe is to adopt tube stamping to make, during punching press there is certain elastic recovery in metal pipe, and elastic recovery is also often inconsistent, cause the hole tolerance of the delivery outlet that punching press makes to be difficult to control, varying aperture amount is large, and input hole is little tubaeform in aperture mostly, makes flux distribution uneven, welding quality is unstable, and branch pipe soldering point easily ftractures; The metallographic structure at punching press position is damaged, easy trickle cracking under hyperbaric environment; All these make existing branch pipe resistance to compression strength poor, reveal incidence rate high.

The delivery outlet quantity of described multiple-pass joint is two, and output tube quantity is also two, and input hole center line equates with the distance of two delivery outlet center lines.
Multiple-pass joint outer side wall between two delivery outlet center lines is two planes, guarantees that the hole wall between two delivery outlets has enough intensity.
The manufacture method of refrigeration pipe aluminium branch pipe, is characterized in that, this manufacture method mainly comprises multiple-pass joint manufacturing process and supplying tube, output tube welding procedure, when multiple-pass joint is manufactured, adopt the aluminium alloy extrusions that forms through extruding or through the aluminium alloy castings of die cast as multiple-pass joint matrix, mainly comprise that delivery outlet processing and input hole process two procedures, in delivery outlet manufacturing procedure, on the blank workpiece of producing according to multiple-pass joint length dimension, according to the size of delivery outlet, on the end face of blank workpiece one end, first use drilling machine and bit bore to process the datum hole of delivery outlet, then do not change clamping and use drilling machine and end mill spot-facing to process the jack part of delivery outlet, in input hole manufacturing procedure, use lathe dog clamping to drive workpiece rotation, and use drill bit according to the size Drilling operation of input hole, to go out the datum hole of input hole on blank workpiece the other end end face, then the constant folder that changes the outfit uses lathe and end mill spot-facing to process the jack part of input hole, still the constant folder that changes the outfit changes the end mill isometrical with datum hole into datum hole is carried out to spot-facing processing, input hole datum hole bottom is processed into flat, then change boring cutter into input hole is carried out to Boring, bore hole length is between at the bottom of input hole hole at the bottom of delivery outlet hole, radius of bore is the spacing of input hole center line and delivery outlet center line, at the bottom of the taper auxiliary hole of perforation one side of removal input hole, thereby removing medium circulation hinders, after multiple-pass joint manufacture completes, supplying tube and output tube are inserted to input hole and delivery outlet is welded and fixed.
In above-mentioned manufacture method, the step end face of usining on input hole and delivery outlet hole wall when supplying tube and output tube welding is as location end face.
In above-mentioned manufacture method, welding method is used ac tungsten inert gases welding or pulsed tungsten argon arc weld(ing).
The present invention is by adopting extruded aluminium section as material, the aluminium multiple-pass joint that turning input hole and delivery outlet are made, can reach following beneficial effect: 1, resistance to compression strength is high, disclosure risk is little, the intensity of extruded aluminium section is high, input hole and delivery outlet adopt cutting to make, make two pore wall thicknesses between delivery outlet large, hole wall can not be subject to punching press damage, improved resistance to compression strength, the aperture, hole that cutting is made is consistent, precision is relatively high, solder flux is at supplying tube, between output tube and boring ratio in distribution uniform, improved welding fastness, all these is that aluminium branch pipe resistance to compression strength of the present invention is high, disclosure risk is little, 2, improve manufacture up-to-standard rate, reduced waste of material, and used the aluminium that price is lower to replace the higher copper material of price, reduced cost of material and processing cost.
