Description
Technical field
The present invention relates to copper pipe production technical field, in particular to realize copper pipe quantity-produced method and apparatus.
Background technique
Mock platina in copper pipe refers to that the content of zinc in ormolu is greater than 30% copper alloy.Mock platina tubing
One of copper and copper-alloy pipe-material major product, Mock platina tubing with its high intensity, high-quality corrosion resistance, product it is antibacterial
Property, good surface smoothness are widely used in: the industries such as bathroom, hot-water heating, lamp decoration and ship condenser.Mock platina tubing
Production technology is main are as follows: two rod cold rolling of semi-continuous casting → hot extrusion → period → multi-pass annealing and linear stretch.The work
Skill mainly has following deficiency:
Mock platina is different from red copper and high-copper low brass, is hardened due to the increase of Zn content in copper, intermetallic composite coating
Therefore speed is carrying out cold working process and must anneal in time to reduce the hardness of product recovery product much larger than the latter
Extension property, in order to the production and processing of later process.For the ease of the production of subsequent Mock platina tubing, tubing is in two rods
Be intended to interrupt → anneal after cold rolling → acid cleaning process can carry out subsequent line stretching.This processing arrangement substantially reduces life
Efficiency is produced, while tubing is intended to carry out head processed to be stretched after interrupting, and reduces finished product rate.Conclude the above content technique
Mainly there is following deficiency:
(1), linear reciprocation stretches, and production efficiency is low, productive labor intensity is big, realizes that automation difficulty is high, cannot achieve
Consecutive production.
(2), it is intended to be cut off after stretching per pass, anneals, pickling, makes first-class auxiliary process again, finished product rate is low.
(3), pickling is carried out after product annealing remove product surfaces externally and internally oxide, to guarantee product surface finish,
Therefore it is unfavorable for environmental protection, while increases production cost.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of realization copper pipe quantity-produced method and apparatus.
Used technical solution to solve above-mentioned technical problem: a kind of realization copper pipe quantity-produced method, feature
It is: increases welding sequence after two roller periodic cold rolling processes, the copper pipe of roll forming is successively welded, is then advanced to
Coil pipe stretches after few primary annealing.
On the basis of the above, inert gas is filled in the copper pipe after coil pipe.
On the basis of the above, in annealing, progress hydrogen and nitrogen gas is mixed gas protected.
On the basis of the above, cooling after annealing uses water cooling.
Another technical solution used by solve above-mentioned technical problem: a kind of realization copper pipe quantity-produced equipment, packet
Include two roller periodic cold-rolling mills, annealing furnace and the spinner block tenside equipment set gradually, it is characterised in that: cold in two roller periodics
Bonding machine is set between milling train and annealing furnace.
Using brought by the present invention the utility model has the advantages that the present invention is by being welded into a copper pipe for more copper pipes, after realization
Continuous is continuously elongated, to realize copper pipe continuous production, improves production efficiency and finished product rate.Reduce labor in production process
The labor intensity of dynamic person.The area occupied of equipment can be reduced, disk draws occupation area of equipment to be far smaller than accounting for for linear stretch machine
Ground area.Copper pipe quantum of output on unit area is far longer than linear stretch production method.Production process eliminates pickling process, has
Conducive to environmental protection.
Detailed description of the invention
Fig. 1 is the structural schematic diagram that the present invention realizes copper pipe quantity-produced equipment.
Specific embodiment
As shown in Figure 1, a kind of realization copper pipe quantity-produced method, increases after traditional two roller periodic cold rolling processes
Welding sequence successively welds the copper pipe of roll forming, and coil pipe stretches after then advancing to less primary annealing.By by more copper
Pipe is welded into a copper pipe, in order to subsequent continuously elongated.According to the degree that copper pipe stretches, one or many drawings can be carried out
It stretches.When welding, it can polish flat as needed to the end of copper pipe.
Copper pipe inner surface oxidation after coil pipe stretches in order to prevent, can fill inert gas in the copper pipe after coil pipe, and
Both ends are jumped a queue, to prevent copper pipe inner surface from aoxidizing.
Copper pipe aoxidizes outer surface in annealing in order to prevent, and it is mixed gas protected to carry out hydrogen and nitrogen gas in annealing.Toward annealing
Furnace fills high proportion hydrogen and nitrogen mixed gas, and wherein hydrogen accounting is up to 75%, nitrogen accounting 25%.In order to avoid high ratio
Example hydrogen gas mixture has an impact periphery atmosphere, and gas outlet end realizes discharge by the mode that mixed gas is burnt, and reaches
The purpose of Environmental Safety.
Further, the cooling of copper pipe after annealing uses water cooling.Cooling zone is set in annealing furnace outlet section, passes through circulation
Cooling water mode cools down the copper pipe in annealing furnace, reaches room temperature shape after annealing copper pipe comes out from annealing outlet of still to realize
Condition avoids copper pipe surface oxidation from occurring.
Realize that copper pipe quantity-produced equipment includes the two roller periodic cold-rolling mills set gradually, annealing furnace 1 and circle
Disk stretching-machine 2, it is characterised in that: bonding machine 3 is set between two roller periodic cold-rolling mills and annealing furnace 1.Annealing furnace 1 is using pipe
The heating of formula annealing furnace, annealing furnace 1 uses spiral wound heating wire.
The copper pipe come out through two roller periodic cold rolling mills can be stored first, and subsequent Welder can also be directly carried out
Sequence.It should be cleaned before copper pipe welding, remove the remaining greasy dirt in copper pipe outer surface, while polishing end, guarantee copper pipe
End it is regular, to facilitate the subsequent welding of copper pipe and annealing.More copper pipes are successively welded into a copper pipe.The copper pipe being welded
It can first store, can also directly carry out subsequent annealed tensile.To be stored, Ying Caiyong coiler disk at coil pipe, in order to
Storage and transportation, while both ends are jumped a queue after filling inert gas in copper pipe.The copper pipe stored before carrying out annealed tensile should first will through rectify
Straight machine aligning.Copper pipe is heated to 450 DEG C~500 DEG C in annealing furnace, then is cooled to room temperature.In annealing process using high hydrogeneous
Hydrogen-nitrogen mixture gas protection, wherein hydrogen and nitrogen gas body ratio be 3:1, hydrogen content 75%, nitrogen content 25%.Gaseous mixture
Body burns before discharging, is conducive to the recycling of protective gas safety and environmental protection.Copper pipe after stepping back is drawn through spinner block tenside equipment
At coil pipe.The coil pipe filling inert gas being drawn into, and both ends are jumped a queue.The coil pipe being drawn into can also carry out again as needed
Annealed tensile.
