Description
Technical field
The invention belongs to operating method, and in particular to a kind of Medium drawing mach ine annealing operation method.
Background technology
At present, due to the copper scrap resource-constrained that the country is produced, imbalance between supply and demand is increasingly protruded, steel-core-aluminium on the market
Copper in twisted wire also uses original copper product, so greatly constrains the production of steel-cored aluminium strand；In addition, production steel-core-aluminium
The equipment of twisted wire falls behind, and is only used for producing the twisted wire of single specification.
It is therefore proposed that a kind of Medium drawing mach ine annealing operation method is the problem of the invention to be studied.
The content of the invention
To solve, waste of material is more in the prior art, be only used for producing the shortcoming of the twisted wire of single specification, so as to provide
A kind of Medium drawing mach ine annealing operation method, prepare in advance hypoxemia or oxygen-free copper-wire, Medium drawing mach ine, annealing machine, winch, extruding machine and into
Cable machine, follows the steps below operation：
The first step, it is using the winch that the two ends of copper cash are stranded；
Second step, carries out stretching drawing using the copper cash after the Medium drawing mach ine strand；
3rd step, the copper cash being pulled through using annealing machine to stretching is made annealing treatment；
4th step, completion is extruded by the extruding machine simultaneously by the screen layer, insulating barrier, insulation screen of copper cash；
5th step, using the cable-former is by screen layer, insulating barrier, insulation screen and stretches the copper cash hinge joint stranding after drawing；
6th step, using the dress wrapped steel band of armour head cable-former；
7th step, extrude sheath is carried out using extruding machine to low-voltage cable, the crosslinked cable of different size.
Further, in addition to test procedure, the test procedure includes doing partial discharge test to high-tension cable, uses office
Put test equipment and shelf depreciation and disruptive test are carried out to crosslinked cable.The annealing includes heating stepses and cooling is walked
Suddenly, first copper cash is heated using heater, then copper cash cooled down using cooling device.The heating stepses and
There is an interval time, the interval 10 ~ 20 minutes between cooling step.Natural cooling is used to copper cash within interval time.
Further, in heating stepses, the environment temperature of heating reached 200 DEG C -300 DEG C in 120 minutes.
Having the beneficial effect that relative to prior art of the invention：
The invention provides a kind of Medium drawing mach ine annealing operation method, good reliability, the properties of product being made are good, and save former material
Material, cost reduction meets the cable production of different size.
Brief description of the drawings
Fig. 1 is the module diagram of Medium drawing mach ine annealing operation method of the present invention.
