Description
Technical field
The preparation method and the equipment therefor that the present invention relates to a kind of steel wire spiral silk, belong to mine safety material manufacturing method and equipment technical field.
Background technology
Aspect mine safety guarantee, be widely used supporting mesh safety support is carried out in the tunnel in mine and getting working face, to ensure mine and miner's personal safety.Supporting mesh is the most general a kind of supporting means that use in mine operation.
Using the most general supporting mesh is at present the rhombus net that a kind of iron wire is weaved into.This iron wire rhombus net is simple in structure, and processing cost is low, has market very widely.But the weight capacity of iron wire rhombus net is less, if improve the weight capacity of supporting mesh, only having overstriking iron wire diameter or with the better material substitution iron wire of intensity, is a real problem but the weight capacity of how to accomplish to improve supporting mesh does not increase again the cost of manufacture of supporting mesh.Overstriking iron wire diameter can improve material and processing cost, and market is difficult to accept.The intensity of steel wire is greater than iron wire from far away, and the price of steel wire is only a little more than iron wire, use diameter to be less than the braided steel wire supporting mesh of iron wire, in the situation that stretching resistance meets the demands, material cost can be saved a lot, and therefore adopting steel wire to replace iron wire braiding supporting mesh is the best-of-breed technology scheme that is easy to expect; But existing braider must be divided into two groups by the steel wire of input in the time of knitmesh, one group is raw silk rings, and another group is taenidium; The steel wire length of taenidium has determined once length that can woven steel fabric.Therefore before braiding, need steel wire first to turn to helical form, be placed on holding in fiber tube or be enclosed within and holding outside fiber tube of braider, as one group of input silk of braider.During at present with iron wire coiling taenidium, that iron wire one end is through in the hole of steel pipe walls, driven by motor steel pipe rotates iron wire one circle circle is wrapped on steel pipe closely, after iron wire is wrapped over steel pipe, iron wire is cut off, and iron wire can form the taenidium of marshalling on steel pipe.But with after the alternative iron wire of steel wire, when steel wire is wrapped over after steel pipe cut off, steel wire once will all flick, can not be neat be arranged on steel pipe, therefore adopt the method for iron wire coiling taenidium not to be suitable for steel wire, coiling does not go out the desired steel wire spiral silk of braider.Process steel wire taenidium if purchase special processing equipment, because special equipment structure is more complicated, price is also relatively high, can cause the increase of equipment investment and cost of manufacture, causes the raising of total production cost and selling price.If use for reference the preparation method of spring, first by wire annealing, wait coiling to complete and quench again afterwards; But also will inevitably strengthen cost of manufacture by a series of heat treatment steps such as annealing, quenchings, in addition steel wire by heat treatment after, also can have a certain impact to tensile strength.Exactly because above-mentioned reason, although the intensity of steel wire supporting mesh is far above iron wire supporting mesh as you know, owing to being difficult to use with simple method and device, to be made into for the steel wire spiral silk of braider lower than the production cost of iron wire be that steel wire supporting mesh can not get the key problem in technology of applying always.
