of the spray material for the uniform processing of the area of the bead processing The present invention relates to the nozzle of the workpiece t~, particularly regarding the processing of the width of the bead Use a spray nozzle. [Prior Art] In the past, the bead processing technology has been continuously used in the field of surface processing such as deburring, fine-faced, and de-flowing of consumables, but in recent years, substrates for solar cell modules and electropolymerization have been used. The demand for high-speed and uniform cutting of large substrates such as displays continues to increase. In the bead processing, a nozzle which ejects as a jet stream (solid-gas two-phase flow) of a mixed fluid supplied from a compressed air supply source and an injection material (abrasive material) supplied from an injection material supply source is used. The front end portion of the injection nozzle for bead processing which is generally widely used has an injection port having a circular cross section in which the width of the mixed fluid is narrow. In the case where the nozzles of the two people are known to cover the wide-width region, the field A of the bead processing may be used instead of the circular cross-section having a narrow width, and the bead processing having a rectangular ejection opening that expands the ejection opening laterally may be used. Spray nozzle. However, in such a nozzle having a rectangular cross-section injection port, since the ejection speed at the end portion in the longitudinal direction of the ejection port is lowered, there is a problem that uniform injection processing of the entire width of the ejection opening cannot be covered. In order to solve such a problem, for example, the spray nozzle for bead processing disclosed in Patent Document 1 is provided with a polishing material diffusion portion which is gradually narrowed in the spray direction in the width direction, and is formed in front of the polishing material diffusion portion. Grinding 201117921 A polishing material diffusion chamber composed of an abrasive rectifying unit, a jet of a mixture of an injection material and a compressed gas (solid-gas two-phase flow) is reflowed into an elongated shape and then ejected. Patent Document 1: Japanese Laid-Open Patent Application No. 4287528 (Korea Co., Ltd., Tokyo) [Summary of the Invention] [Problems to be Solved by the Invention] One: Right. The method of the above-mentioned Patent Document 1 is to rectify the solid gas. First, since the two-phase flow of the solid rolling will collide with the inner wall of the diffusing portion of the abrasive material or the turbulent portion of the abrasive material at a high speed, it is extremely poor. Therefore, there is a problem that the constituent members of the nozzle for bead processing are low. The father change frequency becomes two, and the durability change is directed to this problem, and the present invention is capable of processing the high durability of the beading force U to uniformly perform the width of the illusion of the spray nozzle for the bead processing. Means for Solving the Problem] In order to achieve the above object, the present invention uses a spray nozzle for jet-blasting, and the gas portion of the injection portion, the supply of the injection material, and the compressed gas of the nozzle are described as described above. And supplying the compressed gas and the chamber supplied from the injection material mixture L supplied from the supply port to the gas, and the mixture is connected to the mixing chamber and provided in the mixture of the front center solid gas (4). An extended direction material injection portion for injecting a body injection portion from the mixing chamber to the workpiece is characterized in that: the solid-gas two-phase flow injection 4 201117921 square ~ Yu', ten' > 1- first attack gas The injection portion is provided with a second flow path of the flow of the compressed gas, and the fourth portion has (5) σ, and A is perpendicular to the compressed gas to be injected into the cross section von rectangle 丨 & „. The surface is sprayed from the opening, and the gas flow of the reduced gas is expanded: a rectifying portion in the longitudinal direction of the rectangular cross section of the moon; and a second flow path in which the solid-phase two-phase flow is provided in the jet ejecting portion. This first? The square section of the k-way is perpendicular to the direction of the solid-phase two-phase flow, and the longitudinal direction of the rectangular section is the same as the direction of the long side of the 帛1 Μ. ^ The opening of the ιέ nozzle is the rectifying part that compresses the gas: 'L R is in the longitudinal direction of the rectangular section. Thereby, the compressed gas which is rectified to the velocity distribution of the long side t A ΙΑ X* 仏 方向 均 均 均 均 均 均 均 均 均 均 均The shot materials are mixed in the mixing chamber to form a solid-gas two-phase flow, which is introduced into the spray material injection 4. Since the solid-gas two-phase flow is rectified to have a uniform distribution in the longitudinal direction and the density of the sprayed material is uniform, it is possible to cover the area corresponding to the width of the longitudinal direction of the sprayed portion of the sprayed material to uniformly spray the bead processing. . Since the width of the bead processing can be increased once, the processing efficiency of the bead processing can be improved. In addition, since the solid-gas two-phase flow formed in the mixing chamber is directly introduced into the second flow path which is also disposed in the longitudinal direction due to the flow of the rectified compressed gas before the solid-gas two-phase flow is formed, the solid-gas two-phase flow is relatively It is less likely to expand in the second flow path and collide with the inner wall, thereby preventing wear and damage of the second flow path. In addition, since there is no collision of the material to the rectifying portion, there is no wear or damage. As a result, a spray nozzle for bead processing having high durability is realized. The rectifying portion may be disposed inside the second choke channel perpendicular to the long side of the rectangular section of the gas 201117921: the emitting portion and opposite to the center line of the long side - having a flow of the compressed gas extended to the gas ejecting portion A rectifying member of a rectifying surface in the longitudinal direction of the profiled section. In this case, by the rectifying surface of the rectifying member, the turbulent flow of the compressed gas can be expanded in the longitudinal direction of the rectangular cross section of the gas ejecting portion, so that the flow of the compressed gas is more efficiently rectified in the longitudinal direction. Therefore, the area in which the longitudinal direction of the sprayed material ejecting portion is large can be more efficiently sprayed. The rectifying member is parallel to the jetting direction of the long side of the transverse gas, and the main pressure is good. Such a cross section is, for example, a triangle, a semi-ellipse, a semicircle or the like, but is not limited thereto. As described above, the right cross section parallel to the long side is formed such that the width becomes wider as the direction of the ejection direction of the compression disorder increases, and the eddy current is not generated under the rectifying member, and the flow of the compressed gas can be rectified to both Sentence: The cloth can be uniformly sprayed to process the area of the width direction of the sprayed material ejection portion = the area. J<largeness The above-mentioned rectifying member is the width of the cross section described above.乂 T Fortunately, the reason is that the right width is exceeded, and the velocity of the flow of the rectifying member is lowered, and the velocity distribution of the uniform sentence cannot be achieved. Further, the number of the rectifying members may be plural, and the interval between the rectifying members of the field A is preferably three or more. 〇 'The reason for the adjoining is that if the spacing of the rectifying members is larger than the flow resistance of the small airflow, the &+ μ + sagittal body is large, so the flow velocity of the body is slowed down between the rectifying members and the 201117921 'The jetting speed of the workpiece from the material ejection unit is slowed down, and the machining efficiency is lowered. Further, the rectifying portion may have an inclined surface that expands toward the direction in which the compressed gas is ejected. In this case, the inclination angle 0 of the inclination of the inclined surface satisfies 〇. < θ 7. More ideal. The reason for this is that if Θ exceeds 3.7. The airflow is excessively expanded, and the velocity of the airflow at the end portion of the long direction becomes large, and the machining amount is increased, so that the longitudinal direction of the injection material f-beam portion cannot be uniformly processed. Further, the cross-sectional area si of the opening of the gas injection portion is "the cross-sectional area S2 of the second flow path of the injection material injection portion is sufficient for the phase. l^Sl/S2S〇.4 is more reasonable. If S1/S2 is not full, the injection speed will be too large (four) to be low, and it will not be able to obtain sufficient processing depth. In addition, if Sl/S2 exceeds 〇4, the negative pressure generated in order to attract the spray material in the mixing chamber will be reduced. The present invention provides a bead processing apparatus that ejects an ejected material onto a workpiece and scans the workpiece with a workpiece or a nozzle to perform beading, that is, a sprayed material. The spray nozzle for the bead processing of the present invention is a nozzle for sweeping a cat, or a spray nozzle, and the nozzle is a spray nozzle for bead processing according to the present invention. By using one or more of the above features or a combination thereof, the above-described and other features of the injection nozzle for bead processing of the present invention can be exhibited by the bead processing apparatus of the present invention. The following details [Brief Description of the Invention] The injection nozzle 10 for a bead processing according to the first embodiment of the present invention is described with reference to the drawings. The injection nozzle 1A for bead processing has a compression with a supply of compressed gas. The gas injection unit η connected to the air supply unit f (not shown) is connected to the injection material funnel (not shown) for supplying a predetermined amount of the nozzle material, and supplies the supply unit 12 of the injection material and the gas injection unit η. The mixing chamber 13 that is connected to the supply port 12 and that supplies the compressed gas supplied from the gas injection unit u and the injection material supplied from the supply port 12 to form a solid-gas two-phase flow, and injects the workpiece from the mixing chamber 13 The injection material injection unit 固 of the solid-gas two-phase flow. The mixing chamber 13 is formed inside the injection unit holder 15 in which the gas injection unit "disc injection material 2 unit 丨4 is arranged on a straight line. The portion 11 is formed with a first flow path Ha through which the compressed gas flows, and the i-th flow path i la is perpendicular to the cross-sectional direction of the injection direction of the compressed gas indicated by the arrow 为. The height direction in the figure is long. square In the short-side direction of the cross-section, the height direction in the line of Fig. 1 (8) is the longitudinal direction of the rectangular cross-section. The front end of the gas ejecting portion 1 1 is inclined such that the length of the short side gradually decreases toward the opening portion lib toward the opening portion lib. The portion Uc is provided in the supply port 12 so that the injection portion holder 15 is provided from the long side to the tilting direction (four) lle, and the ejection direction is x (four). With this configuration, the material can be smoothly introduced into the mixing chamber 13' compressed gas. It is easy to be mixed with the spray material to form a solid-gas two-phase flow having a uniform density of the spray material 201117921. The opening 胄i lb of the gas injection portion 1! is formed with a rectifying portion 2G that expands the flow of the compressed gas in the longitudinal direction. The rectifying 胄 2G is provided with a rectifying structure m perpendicular to the long side and symmetrical with respect to the center line of the long side (having a rectifying surface 2ia for expanding the flow of the compressed gas in the longitudinal direction), and dividing the first stream Road 1U. In order to expand the flow of the compressed gas more efficiently in the long direction, it is preferable to use a plurality of the rectifying members 21. In the present embodiment, the rectifying member 21 has a shape of a long triangular shape in which the transverse direction d parallel to the long side is formed into a shape having a large width in the ejection direction X of the compressed gas. The rectifying surface 21a is inclined a few degrees outward in the ejection direction X, and the flow of the compressed gas can be expanded in the longitudinal direction. Further, in order to reduce the disturbance of the flow of the compressed gas, it is preferable that the rectifying member 21 itself is disposed so as not to incline the injection direction X. The sprayed material ejecting portion 14 has a second cross section 14a in which a solid-phase two-phase flow introduced from the mixing chamber 13 flows in a cross section perpendicular to the injection direction X. As shown in Fig. 1(C), the long side of the rectangular cross section of the second flow path 14a is formed such that its direction is opposite to the longitudinal direction of the rectangular cross section of the second flow path 11a, and its length and the first flow path 11a are formed. The length of the long sides is substantially the same = the short side is formed to be longer than the short side of the opening 1 lb. When the second flow path 14a' is disposed in the center from the side of the injection port, the long side is short and the short side is short. The ^1, $1 flow uses the spray nozzle 1 of the bead processing of the first embodiment, and the mouth is as follows The bead processing is described. After the compressed gas is supplied from the compressed air supply device to the gas injection unit, the supplied compressed gas flows through the first flow ί λλ. At this time, 201117921 to the mouth, the flow of the compressed gas to the 岣 compressed gas has a flow velocity at the center portion, and the flow velocity becomes slower as it goes to the outer side of the long side. After the flow of the compressed gas reaches the rectifying unit 20 formed in the opening portion of the gas ejecting unit u, the flow of the rectifying surface 2ia of the rectifying member 21 is expanded in the longitudinal direction and rectified to the long side. speed distribution. The rectified compressed gas is injected into the mixing chamber 13 from the gas jetting portion "previous end to the current a, and the injection material is introduced from the supply port. The sprayed material enters into the flow of the compressed gas after being rectified, and is formed to have a velocity distribution in the longitudinal direction of the sentence, and the spray material is dense; the uniform solid-gas two-phase flow. a The solid-gas two-phase flow formed in the Kunming chamber is guided by the second flow path 14a of the shot material ejecting portion 14. Here, the opening of the gas injection unit u and the second flow path 14a are as shown in the figure! (c) The relationship between the household and the household is such that the flow of the solid-gas two-phase flow formed in the mixing chamber 13 is not disturbed in the longitudinal direction: the workpiece is held in a state where the longitudinal direction is uniform and the velocity is distributed. injection. By moving the workpiece to be processed in the short-side direction by the spray nozzle 10 for the bead processing, it is possible to uniformly process the region in which the width of the spray material ejecting portion 14 in the longitudinal direction is large. Thereby, since the width of the one-shot bead processing can be increased, the processing efficiency of the bead processing can be improved. Since the solid-gas two-phase flow formed in the mixing chamber 13 is directly introduced into the second flow path 14a, the solid-gas two-phase flow is less likely to expand inside the second flow path 14a and collide with the inner wall, thereby preventing the second flow path. Wear and damage. Further, since no shot material is washed against the rectifying portion 20', there is no wear or damage. 10 201117921 Hereinafter, a description will be given of a bead processing test using the spray nozzle for jet processing of the present invention. Further, the embodiment of the present invention is not limited to the following test examples. (Test Example 1) In this test example, the influence of the arrangement of the rectifying members 21 on the bead processing state was investigated. The bead processing test of the flat sample is performed using the spray nozzle 10 of the bead processing having the width D of the long side D=18 mm and D=15 mm, respectively, and is processed after the bead processing of the spray nozzle 10 for each bead processing. The contour of the machining depth in the side direction determines whether the bead processing is good or not. The U-piece 21 is formed into a diagonal shape by forming a rectangular shape having a width of 10 mm and a shape of two cross-sections. Fig. 2 shows a line profile in which the width of the long side is used for the processing of the nozzle bead of the 18th position, and the interval B of the adjacent rectifying members 21 is 2% of the machining depth. When the interval B of the rectifying member 21 is 3, it is possible to perform uniform bead processing in which the degree of ice is in the range of 5 to i. Further, in the field where the interval between the rectifying members 21 is made, the amount of the area between the π and the W of the rectifying member 21 is reduced, and the uniform injection molding cannot be performed. The reason is considered to be rectification: 2Γ: The flow resistance of the wide airflow becomes large, so the flow velocity of the airflow injected by the workpiece becomes slower as the flow velocity of the compressed gas is slowed by the difference; ^, the injection force force injection portion 14 changes the processing efficiency of β I Will fall 201117921 low 0 18mm spray bead processing spray nozzle will use the long side width D of 10, the adjacent rectifying member 21 interval BA 2~5mm and the use of the long side width 〇 15 axis of the bead The spray nozzle H) is used to make the result of the bead processing in the case where the interval B of the adjacent "α member 2 1 is 3 mm': the member is not in the long side of the spray nozzle for the bead processing When the width 〇 is 18 ug or 15 mm, it is preferable that the distance b between the adjacent rectifying members 21 is 3 mm or more, as long as the number of the rectifying members 21 adjacent to each other is three or more.

The reason is considered to be that if the rectifying member 21 <width exceeds 1 mm', the velocity of the airflow flowing under the rectifying member 21 is lowered. It is not possible to achieve a uniform velocity distribution on 12 201117921, or to become thinner at the concentration of the rectifying material. The dry cloth, the persimmon of the blasting material of I, is fine, and it is confirmed that the whole is preferable. Further, the width of the dry ^ is ι_ (test example 3). The shape of the rectifying member 2 1 is obliquely broken. The effect of the small shape on the processing state of the bead is examined for 5 weeks. The spray nozzle 10 for the bead processing using the width of the long side and the length of the 18 mm was used to test the bead processing test under the same conditions as in Test Example 1, and it was judged whether or not the bead processing was good. As the rectifying sheet metal member 21', as shown in Fig. 4(A), a shape having one cross section is formed into a rhombus shape and a smaller elliptical shape, and is disposed at the center of the long side. This special shape rectifying member 2 1 Ancient μ 61 Fu 仟 21 has a portion in which the width in the ejection direction is narrowed. When the cross-sectional shape is a rhombic shape, an error occurs in the processing depth and the processed portion and the unprocessed portion are as shown in Fig. 4 (8). The realm of the world is undulating, and there is no need to go into good bead processing. Further, in the case where the cross-sectional shape is expanded, the processing width becomes small, and the boundary between the processed portion and the unprocessed portion is wavy, and good bead processing cannot be performed. The reason for this is considered to be that the portion where the width becomes smaller causes the eddy current to flow under the rectifying member 21. By 2, it can be confirmed that the cross-sectional shape is such that a width such as a triangle, a semi-elliptical 'semicircle, and the like in the direction in which the compressed gas is sprayed becomes wider, and no eddy current flows under the rectifying member 21, and the flow of the compressed gas can be rectified to The uniform speed of the cloth is ideal for uniformly processing the area of the long side of the sprayed portion of the spray material.

As shown in the figure, if S1/S2 is less than 0.1, the jetting speed will be greatly increased.

The number of the rectifying members 2, the arrangement interval, and the like can be appropriately selected in accordance with the processing width for the purpose. According to the injection nozzle 1 of the bead processing of the present invention, the flow of the compressed gas can be expanded in the longitudinal direction of the rectangular cross section by the rectifying unit 2 (the rectifying member 21) in the opening portion 1113 of the gas ejecting portion. Thereby, the compressed gas which is rectified to the long side square && q ώ only the universally distributed speed is mixed with the sprayed material supplied from the supply 埠U in the mixing chamber to form the solid gas two The phase u is introduced into the shot material ejecting unit 14. Since the solid-gas two-phase flow is rectified to have a velocity distribution in the long-side direction and the density of the material to be sprayed is uniform, the width of the long-side direction of the jet-injecting portion 14 can be uniformly processed. In this way, the processing efficiency of the bead processing can be improved due to the width of the can be processed by the __. Since the flow of the rectified compressed gas before the two-phase flow in the solid-rolling process is carried out, the solid-gas two-phase flow formed by the first to third flows is directly introduced into the second flow path 14a which is also disposed in the longitudinal direction, so that the solid gas is two Since the phase flow is less likely to expand inside the second flow path 14a and collide with the inner wall, it is possible to prevent the second flow path w from being worn and damaged, and since the injection material does not collide with the rectifying portion 2, it is not worn or damaged. In this way, the injection nozzle for the bead processing of the second embodiment of the present invention is shown in the longitudinal direction of the injection nozzle 10 of the second embodiment of the present invention. The injection nozzle 10 for bead processing according to the second embodiment differs from the injection nozzle 10 for bead machining according to the first embodiment shown in Fig. 1(B) in that the rectifying unit 2 has an injection direction to the compressed gas. An inclined surface 22 that expands in the longitudinal direction. Since the flow of the compressed gas flowing through the first flow path 丨丨a of the gas injection portion π is guided and expanded outward in the longitudinal direction by the inclined surface 22, the injection processed material can be uniformly sprayed as in the first embodiment. A region in which the width of the longitudinal direction of the injection portion 14 is large. Here, the inclination angle 0 at which the inclined surface 22 is inclined with respect to the ejection direction satisfies 〇. < 0 $3.7° is ideal. The reason is that if 0 exceeds 3 7 . When the airflow is excessively expanded and the velocity of the airflow at the end portion in the longitudinal direction is increased, the amount of machining is increased, and it is not possible to uniformly process the region in which the width of the jet material ejecting portion in the longitudinal direction is large.
