Description
Technical field
The present invention relates to a kind of trickle orifice plate manufacturing technology, particularly a kind of method that adopts the popin band to make trickle orifice plate.The inventive method is applicable to the making of multiple trickle orifice plate, and the inventive method is particularly useful for through hole nominal diameter≤2mm, thickness of slab 〉=0.5mm, via area (via count * single hole area equals via area) and the making of orifice plate area than the intensive regularly arranged trickle orifice plate of convergence π/4.
Background technology
Trickle orifice plate now is widely used in fluid, and (liquid comprises water, oil, organic solvent and solution etc. thereof, gas comprises air, discharging waste gas and chemical process gas thereof, flue gas etc.) filtration, purification, use the filter material layer supporting as, or directly as multiple occasions such as filter screen and melt-out spinning ventilating hole plates, trickle orifice plate in above-mentioned occasion use, the trickle orifice plate of especially intensive rule, what generally adopt at present is that screen cloth with various types substitutes, perhaps adopt and on flat board, carry out machine drilling, laser boring, the method of Wire EDM is made trickle orifice plate, the defective that the preparation method of existing trickle orifice plate mainly exists is: (1) screen strength is poor, and service life is low; (2) the through hole resistance of orifice plate is big, can't reach the actual requirement of trickle orifice plate; (3) manufacture difficulty is big, and yield rate is low, and cost performance is low.Trickle orifice plate has certain requirement to the density of fine holes, owing to be subjected to the restriction of fine holes density, therefore makes difficulty, and yield rate is low, even adopt the prior art that has to make, but the cost of manufacture costliness, cost performance is very low, and is less economical.Especially below making through hole nominal diameter 1.0mm, through hole sectional area summation and orifice plate area be during than the intensive trickle orifice plate of convergence π/4 values, the preparation method of prior art more is difficult to guarantee to make quality, yield rate is lower, cost of manufacture is expensive more.Because trickle orifice plate market demand is very huge, can't produce the trickle orifice plate of cost performance height, good product quality, long service life at an easy rate with existing preparation method, people press for that a kind of preparation method is simple, cost of manufacture is low, yield rate is high, the preparation method of the trickle orifice plate of good product quality solves the technical barrier of making trickle orifice plate at all.
Summary of the invention
The objective of the invention is at the deficiencies in the prior art, provide that a kind of preparation method is simple, cost performance is high, good product quality, cost of manufacture are low, the method for the trickle orifice plate of making of long service life.
The technical scheme that realizes above-mentioned purpose is: a kind of method of making trickle orifice plate, described method comprises the steps: a waveform band and a straight band are superimposed together, form a side has the waveform curved surface for the flat face opposite side popin band, again the popin tape beginning end is fixed on the central shaft, be that the center is wrapped in some circles on the central shaft with the popin band then with the central shaft, after twining end the end end of popin band is fixed, produced trickle orifice plate.
Another kind of method of making trickle orifice plate, described method comprises the steps: one one side is fixed on the central shaft for the initiating terminal that the flat face opposite side has the popin band of waveform curved surface, be that the center is wrapped in some circles on the central shaft with the popin band then with the central shaft, after twining end the end end of popin band is fixed, produced trickle orifice plate.
Further, first kind of technical scheme made in the method for trickle orifice plate, the straight tape thickness M≤2mm in the described popin band, width B ' 〉=0.5mm, the waveform tape thickness S≤2mm in the described popin band, width B 〉=0.5mm, pitch of waves P≤the 2mm of the waveform curved surface of described popin band, wave height H≤2mm.
Further, second kind of technical scheme made in the method for trickle orifice plate, and the flat face in the described popin band is to thickness the M '≤2mm of waveform curved surface trough point, the width B of popin band " 〉=0.5mm; the pitch of waves P≤2mm of the waveform curved surface of described popin band, wave height H≤2mm.
Further, first kind or second kind of technical scheme are made in the method for trickle orifice plate, and the waveform curve form of described popin band is any in sinusoidal, circular arc, trapezoidal, profile of tooth or the dove-tail.
Further, first kind or second kind of technical scheme are made in the method for trickle orifice plate, and described central shaft is that the cross section is circular solid shafting, is circular hollow tubular axis for the cross section perhaps.
Further, first kind or second kind of technical scheme are made in the method for trickle orifice plate, and described trickle orifice plate is provided with the support reinforcing device.
Further, described support reinforcing device includes rib spoke inner edge, rib spoke outer rim, goes up rib spoke and following rib spoke, rib spoke outer rim is arranged on the trickle orifice plate outside, rib spoke inner edge is arranged on the central shaft outside, last rib spoke and following rib spoke are separately positioned on the two end faces up and down of trickle orifice plate, and upward the rib spoke all is connected with rib spoke outer rim with rib spoke inner edge with following rib spoke.
Employing the inventive method has the following advantages: (1) preparation method is simple, good product quality, long service life.Trickle orifice plate of the present invention is owing to be to be formed by the coiling of popin band, and preparation method is simple, and the popin carrying material can be selected arbitrarily as required, and popin band strength and rigidity are very good, thereby the trickle orifice plate intensity of producing is good, long service life; And after increasing the support reinforcing device, the intensity and the rigidity of trickle orifice plate are better, longer service life, and trickle orifice plate is bright and clean, and the through hole resistance is little, reaches the actual requirement of trickle orifice plate fully, and fine holes panel products quality is very good; (2) cost of manufacture is low, cost rate height, cost performance height.The inventive method has realized the making of the trickle orifice plate of plurality of specifications, can also realize difficulty high through hole nominal diameter≤2mm, thickness of slab 〉=0.5mm, via area (via count * single hole area equals via area) and of the making of orifice plate area than the intensive regularly arranged trickle orifice plate of convergence π/4, adopt the inventive method cost of manufacture low, yield rate is but very high, the cost performance height has extraordinary economy.The present invention changes traditional fine holes board manufacturing method, method is ingenious, solve people with the present invention simple preparation method and urgently wished the technical barrier that solves, make original making difficulty, the trickle orifice plate of expensive high-quality by preparation method of the present invention, realized the widespread usage that trickle orifice plate is multi-field, the inventive method can guarantee the mass parameter of trickle orifice plate, can control the strength rigid of orifice plate arbitrarily, satisfy every requirements such as service life and Technological Economy, preparation method is simple, cost performance height, good product quality, cost of manufacture is low, long service life.
