Abstract
A method for embossing various patterns on a surface of a stainless steel pipe using an etching technique is disclosed. The method for embossing an elaborate etched pattern on a surface of a stainless steel pipe, comprising the steps of: printing a surface of a stainless steel pipe with acid resisting ink, drying the stainless steel pipe in a drying room for a predetermined time, and etching the surface of the stainless steel pipe by eroding the remaing surface areas of the stainless steel pipe not coated with the acid resisting ink in an eroding bath filled with acid using an electrical technique.
Description
The present invention relates to a kind of use etching technique and carve various method of patterning at stainless steel pipe surface.
At present, for the stainless steel tube that is carved with etched pattern thereon, along with material of construction, luxurious as house rail post trend, its demand increases rapidly, and its expansion of many uses.
Normally used this stainless steel tube carves pattern by utilize etching technique on stainless steel plate, then it is rolled into tubulose with circle, produces the high problem of complicate fabrication process and manufacturing cost thus.And being carved with the stainless steel tube of etched pattern, i.e. the product of finishing by this manufacture method is owing to can not have a perfect outward appearance along tubular axis to forming coarse welding portion.
The present invention seeks to provides a kind of method that directly carves very meticulous etched pattern at stainless steel surface for addressing the above problem, and thus, can be carved with the stainless steel tube of etched pattern with simple manufacturing process and low manufacturing cost manufacturing.
Above-mentioned purpose of the present invention is achieved by a kind of method that directly carves a meticulous etched pattern on stainless steel pipe surface is provided, and this method may further comprise the steps: the surface of (a) printing stainless steel tube with acid-proof ink; (b) in kiln with a dry scheduled time of stainless steel tube; (c) make the not surface of etching stainless steel tube, multiplexe electric technology corrodes stainless steel tube in the etching tank of containing acid the residual surface zone that is not coated with acid-proof ink.
In conjunction with the drawings with reference to the following detailed description, will clearer and better understanding to more complete evaluation of the present invention and its incidental many advantages, wherein same Reference numeral is represented same or analogous building block.Wherein:
Fig. 1 shows that the screen plate printing method that utilizes one embodiment of the invention prints the view of the technology on stainless steel one surface with acid-proof ink.
Fig. 2 is the view that shows the technology of one embodiment of the invention etching one stainless steel pipe surface.
Fig. 3 is the local amplification view of being got along Fig. 2 I-I line.
Now, do not describe the preferred embodiments of the present invention with reference to the accompanying drawings in detail.In whole figure, it should be noted that the identical or suitable parts with said function will mark with identical reference number or letter.In the following description, the detailed description such as each building block of physical circuit is for the present invention is more fully understood.Obviously, concerning a person skilled in the art, need not do concrete detailed description the in detail to them and just can implement the present invention.Can not make unclean known function of theme of the present invention and structure hereinafter with describing in detail.
With reference to accompanying drawing, shown in Figure 1ly on the surface of stainless steel tube A, form the view of the technology of a pattern with acid-proof ink, wherein, the stainless steel tube both ends are seated in two free peace of energy and trackslip between the upper surface of moving supporting roll 1,2.
Pressure roll 3 rotatably is placed on the top of stainless steel tube A, and the web plate 4 that is formed with pattern to be printed is suitable for by the bottom of pressure roll 3 and the top of stainless steel tube A.
Web plate 4 is by the pressure roll 3 that rotates and the stainless steel tube A that rotates with the linear velocity identical with pressure roll 3, so that a screen printing layer with acid-proof ink pattern forms on the circumferential surface of stainless steel tube A.
The stainless steel tube A that is formed with the screen printing layer as mentioned above on it is taken out, then dry preset time in kiln.
In aforesaid the present invention, though use the screen printing technology on stainless steel tube A surface, to form screen printing layer with acid-proof ink pattern, but should be appreciated that, without departing from the present invention, the person skilled in the art to use any other method to form the screen printing layer on stainless steel pipe surface be tangible.
Fig. 2 is the view of technology that shows the acid etching stainless steel pipe surface of one embodiment of the invention.
Specifically with reference to figure 2 illustrated formations of the present invention, numeral 5 expression etching tanks, numeral 6,6 ' respectively represent a copper bar, suspension bracket pipe of numeral 7 expressions, numeral 7 ' mounting block of expression, stereotype of numeral 8 expressions, numeral 9 an expression direct current (DC) power supplys, and variohm of numeral 10 expressions.
As shown in Figure 3, the two ends of copper bar 6 were to be electrically connected it in the middle of a pair of suspension bracket pipe 7 was suspended on respectively with direct supply 9, and many isolated at certain intervals stainless steel tube A are fixed on the two suspension bracket pipes 7 as follows: manyly be formed on the mounting blocks 7 of suspension bracket pipe 7 inboards ' be fitted to the respectively two ends of stainless steel tube A at certain intervals along suspension bracket pipe 7 vertical.
Middle copper bar 6 is electrically connected with the positive pole (+) of direct supply 9, thereby the stainless steel tube A in etching tank 5 also and positive source (+) connection.
On the other hand, many lead (pb) plate 8 be suspended in respectively the copper bar 6 of both sides ' on, it has certain intervals each other, and is electrically connected with the negative pole (-) of direct supply 9.
In a preferred embodiment of the invention, be full of acid in the etching tank 5, mixing acid particularly, it is by the phosphoric acid (a) of 70% concentration, the sulfuric acid of 98% concentration (b) and form a by the mixture (c) that the surfactant of the oxysuccinic acid of the succsinic acid of 40% volume, 20% volume and 20% volume mixes: the volume ratio of b: c is 6: 3: 1.
The temperature that keeps etchant is in the 50-60 degree, from stainless steel tube A4-6 minute in the galvanic current inflow etching tank 5 of direct supply 9, so that it is galvanic corrosion is stood in the residual surface zone that is not coated with acid-proof ink of stainless steel tube A under the mixing acid effect, and etched.
After finishing stainless steel A surface etching as mentioned above, stainless steel tube A is put in caustic soda (NaOH) solution, the dissolved and removal of the acid-proof ink layer of stainless steel tube A, water carries out the flushing of stainless steel tube A and is dried then, finishes the present invention thus.
Therefore, the advantage of the stainless steel tube A of etched pattern formed according to the present invention is, the line of stainless steel tube A carves that part is even, level and smooth, glossy, it makes the stainless steel tube that is carved with meticulous etched pattern with simple production technology and lower production cost mass production become possibility.
By diagram and description, should understand that do not breaking away under the actual range condition of the present invention, for those skilled in the art element being replaced to have various variations, modification and equivalent to the preferred embodiment of the present invention.Therefore the invention is not restricted to finish and disclosed specific embodiment in the best way, but comprise all embodiments in the claim scope.
