技术领域 FIELD

[0002] 本发明涉及在对被加工物喷射喷射材料的喷丸加工中使用的喷嘴,特别地,涉及适合宽广区域的均勻加工的喷丸加工用喷射喷嘴。 [0002] The present invention relates to the use of shot peening nozzle is ejecting the ejection of the workpiece material, in particular, to a uniform processing over a broad region of the shot peening jet nozzle.

背景技术 Background technique

[0003] 以往,在去毛刺、表面变粗糙、以及铸件的流痕(flow mark)去除等表面加工的领域等中使用喷丸加工技术,近年来,高速且均勻地对太阳能电池模块用基板、等离子体显示器等的大型基板进行切削加工的要求高涨。 [0003] Conventionally, deburring, surface roughening, and the casting flow marks (flow mark) removing surface machining and the like in areas such as the use of shot peening technology in recent years, high speed and uniformly to a solar cell module substrate, It requires cutting a large substrate for plasma display or the like high. 在喷丸加工中,使用喷射从压缩空气供给源供给的空气流和从喷射材料供给源供给的喷射材料(研磨材料)的混合流体的喷射流(固气二相流)的喷嘴。 In shot peening, a stream of mixed fluid jet ejecting from the supply source and the compressed air jet flow material (abrasive) materials supplied from the injection supply source (solid-gas two-phase flow) nozzle. 通常广泛使用的喷丸加工用喷射喷嘴的前端部具有喷射混合流体的宽度窄的圆形截面的喷射口。 Shot peening is widely used in general a circular cross section having a narrow ejection ports with the distal portion of the fluid mixture spray nozzle. 在通过一次喷嘴扫描遍及宽广区域进行喷丸加工的情况下,有时使用代替宽度窄的圆形截面而具有喷射口在横向扩展的矩形截面的喷射口的喷丸加工用喷嘴。 In the case of scanning by a single nozzle for shot peening over a wide area, and is sometimes used in the ejection opening having the ejection opening shot peening scale of the nozzle of rectangular cross-section instead of a circular cross section is narrower. 但是,在具有这种矩形截面的喷射口的喷嘴中,在喷射口的长边方向的端部喷射速度下降,因此存在无法遍及喷射口整个宽度进行均勻的喷丸加工的问题。 However, such a nozzle ejection port having a rectangular cross section, the end portion in the longitudinal direction of the ejection speed injection port decreases, there is a problem can not be over the entire width of the ejection openings of uniform shot-peened.

[0004] 为了解决这种问题,例如,在专利文献1所公开的喷丸加工用喷射喷嘴中,设置有由研磨材料扩散部和研磨材料整流部构成的研磨材料扩散室,将喷射材料和压缩气体的混合流体的喷射流(固气二相流)的截面形状整流成细长形状而进行喷射,所述研磨材料扩散部随着朝向喷射方向而宽度方向截面逐渐变窄,所述研磨材料整流部形成在所述研磨材料扩散部的前方。 [0004] In order to solve such a problem, for example, Patent Document 1 discloses a shot peening jet nozzle is provided with a diffusion chamber abrasive material and abrasive abrasive diffusing portion composed of the rectifying portion, and the injection material compression sectional shape of the rectifying mixed fluid jet stream of gas (solid-gas two-phase flow) of elongated shape and is injected into the diffuser portion toward the abrasive jet widthwise direction gradually narrowed cross section, said abrasive rectifying a front portion formed in the abrasive portion of the diffuser.

[0005] 专利文献1 :日本国专利申请第4287528号公报(株式会社不二制作所,东京) 发明内容 [0005] Patent Document 1: Japanese Patent Application Publication No. 4287528 (Fuji Manufacturing Co., Ltd., Tokyo) SUMMARY OF THE INVENTION

[0006] 但是,当利用上述的专利文献1所记载的方法对固气二相流进行整流时,由于固气二相流高速地与研磨材料扩散部或者研磨材料整流部的内壁碰撞,因此容易导致研磨材料扩散部或研磨材料整流部磨损、损伤。 [0006] However, when using the above-described method of Patent Document described in 1 when the solid-gas two-phase flow is rectified, since the solid-gas two-phase flow at high speed collides with the inner wall of abrasive diffusion portion or rectification section of abrasive material, it is easy to diffusing section leading to the abrasive or polishing material rectifying portion wear, damage. 由此,存在喷丸加工用喷嘴的构成部件的更换频率高,耐久性低的问题。 Thus, there is a shot peening nozzle member constituting the frequency of replacement of high and low durability problems.

[0007] 因此,本发明的目的在于实现能够均勻地进行宽广区域的加工、且耐久性高的喷丸加工用喷射喷嘴。 [0007] Accordingly, an object of the present invention is to realize a wide area can be processed uniformly, high durability and shot peening jet nozzle.

[0008] 为了达成上述目的,如第一方面所记载的那样,本发明采用如下的技术装置,喷丸加工用喷射喷嘴具备:气体喷射部,该气体喷射部用于喷射压缩气体;供给口,该供给口用于供给喷射材料;混合室,该混合室分别与上述气体喷射部和上述供给口连通,对从上述气体喷射部供给的压缩气体和从上述供给口供给的喷射材料进行混合,形成固气二相流;以及喷射材料喷射部,该喷射材料喷射部与上述混合室连通,设置在上述气体喷射部的延长 [0008] To achieve the above object, a first aspect as described above, the present invention adopts the following technical means by shot peening jet nozzle includes: a gas injection section, a gas injection unit for injecting the compressed gas; supply ports, the supply port for supplying the injection material; mixing chamber, the mixing chamber are communicated with the gas injection portion and the supply port, the compressed gas supplied from the gas injection unit and the injection material is supplied from the supply port are mixed to form a solid-gas two-phase flow; and a spray material injection portion, the injection material ejecting portion communicating with said mixing chamber, the gas jet is provided in the extension portion

3方向,用于朝被加工物喷射从上述混合室导入的固气二相流,其中, Third direction for ejection toward the workpiece introduced from the solid-gas two-phase flow mixing chamber, wherein

[0009] 在上述气体喷射部设置有供压缩气体流动的第一流路,该第一流路具有开口和整流部,该整流部的与压缩气体的喷射方向垂直的截面形成为长方形截面,用于使从上述开口喷射的压缩气体的气流在上述长方形截面的长边方向扩展, [0009] In the gas ejection portion is provided with a first flow passage for flow of the compressed gas, the first flow passage and a rectifying portion having an opening cross section perpendicular to the injection direction of the rectifying portion of the compressed gas is formed as a rectangular cross-section, for in the longitudinal direction of the rectangular cross section of the opening extend from the stream of compressed gas injection,

[0010] 在上述喷射材料喷射部设置有供固气二相流流动的第二流路,该第二流路的与固气二相流的喷射方向垂直的截面形成为长方形,且该第二流路的长方形截面的长边方向的朝向与第一流路的长边方向的朝向一致。 [0010] In the spray material injection portion provided with a second flow passage for the solid-gas two-phase flow of the flow cross section perpendicular to the ejection direction of the solid-gas two-phase flow of the second flow passage is formed as a rectangular shape, and the second consistent orientation toward the longitudinal direction of the rectangular cross section of the longitudinal direction of the flow path and the first flow path.

[0011] 在气体喷射部的开口部中,能够利用整流部使压缩气体的气流在长方形截面的长边方向扩展。 [0011] In the opening portion of the gas ejection portion, the rectifying unit can be utilized so that the compressed gas stream is expanded in the longitudinal direction of the rectangular cross section. 由此,能够使在长边方向被整流成均勻的速度分布的压缩气体与从供给口供给的喷射材料在混合室中混合而形成固气二相流,并将该固气二相流导入喷射材料喷射部。 Thus, compressed gas in the longitudinal direction is rectified into a uniform velocity distribution of the injection material is mixed with supplied from the supply port in a mixing chamber to form a solid-gas two-phase flow, and the solid-gas two-phase flow into the spray material injection portion. 该固气二相流被整流成在长边方向具有均勻的速度分布,并且,喷射材料的密度均勻, 因此能够遍及与喷射材料喷射部对应的宽广区域均勻地进行喷丸加工。 The solid-gas two-phase flow is rectified into a uniform velocity distribution in the longitudinal direction, and a uniform density of injected material, shot peening can be performed over a wide area with uniformly ejecting portion corresponding to the material ejection. 由此,能够扩宽一次能够进行喷丸加工的宽度,因此能够提高喷丸加工的加工效率。 Thus, a possible widening of the width of the shot peening, it is possible to improve processing efficiency peened.

[0012] 并且,由于在形成固气二相流之前对压缩空气的流动进行整流,因此,在混合室中形成的固气二相流直接被导入配置在相同的长边方向的第二流路,因此固气二相流在第二流路的内部扩展而与内壁碰撞的情况变少,能够防止第二流路磨损、损伤。 [0012] Further, since the rectified flow of compressed air prior to forming the solid-gas two-phase flow, and therefore, the solid-gas two-phase flow formation in the mixing chamber is directly introduced into the second flow passage arranged in the same longitudinal direction Therefore solid-gas two-phase flow within the second flow passage being extended to the case of a collision of the inner wall is reduced, the second flow path can be prevented from wear and damage. 此外,由于喷射材料不会与整流部碰撞,因此整流部也不会磨损、损伤。 Further, since the injected material does not collide with the rectifying section, and therefore the rectifying portion is not worn, damaged. 由此,能够实现耐久性高的喷丸加工用喷射喷嘴。 Accordingly, high durability can be achieved by shot peening jet nozzle.

[0013] 在上述整流部中,在上述第一流路的内部,以与长边垂直且相对于长边的中心线对称的方式设置有整流部件,该整流部件具有使压缩气体的气流在上述气体喷射部的长方形截面的长边方向扩展的整流面。 [0013] In the rectifying section, inside the first flow passage, and with respect to the longitudinal vertical centerline symmetrically disposed with the longitudinal member rectifier, which rectifier means has a pressurized gas stream in the gas longitudinal direction of the rectangular cross section of the injection portion extended rectifying surface.

[0014] 在该情况下,能够利用整流部件的整流面使压缩气体的气流在气体喷射部的长方形截面的长边方向扩展,因此能够更加高效地将压缩气体的气流在长边方向整流成均勻的速度分布。 [0014] In this case, the use of a rectifying surface of the rectifying section of the gas stream the compressed gas is expanded in the longitudinal direction of the rectangular cross section of the gas injection portion, and therefore can be more efficiently compressed gas stream is rectified into a uniform in the longitudinal direction the velocity distribution. 因此,能够更加高效地对喷射材料喷射部的长边方向的宽广区域均勻地进行喷丸加工。 Therefore, the wide area of ​​the longitudinal direction of the material ejection portion ejecting a shot blast process is performed more efficiently uniformly.

[0015] 优选上述整流部件的与上述长边平行的横截面形成为宽度朝向压缩气体的喷射方向变宽的形状。 [0015] with the long sides parallel to said cross-sectional shape is formed toward the width direction of the compressed gas injection is preferably widens the rectifying member. 这种横截面例如能够举出三角形、半椭圆、半圆等,但是并不限定于这些形状。 Such include for example a triangular cross-section, semi-elliptical, semi-circular, etc., but is not limited to these shapes.

[0016] 这样,当将与长边平行的横截面形成为宽度朝向压缩气体的喷射方向变宽的形状时,不会在整流部件的下游产生涡流,能够将压缩气体的气流整流成均勻的速度分布,能够对喷射材料喷射部的长边方向的宽广区域均勻地进行喷丸加工。 Rectifying the airflow [0016] Thus, when the shape of the width direction of the gas injected toward the compression widens the cross section is formed parallel to the long sides, no vortex at the downstream rectifying member can be compressed into a uniform gas velocity distribution, it is possible to perform shot peening uniformly wide area of ​​the longitudinal direction of the spray material ejection portion.

[0017] 优选上述整流部件的上述横截面的宽度在Imm以下。 It said cross-sectional width of the [0017] Preferably, the rectifying member in the following Imm.

[0018] 这是因为,当宽度超过Imm时,整流部件的下游处的气流的速度下降,因此无法达成均勻的速度分布。 [0018] This is because, when the width Imm, exceeds, the speed of the airflow at the downstream rectifying member decreases, and therefore unable to reach a uniform velocity profile.

[0019] 并且,上述整流部件也可以配置有多个,在该情况下,优选邻接的整流部件的间隔在3mm以上。 [0019] Further, the rectifying means may be configured with a plurality, in this case, the spacer member is preferably adjacent commutator less than 3mm.

[0020] 这是因为,当整流部件的间隔比3mm小时,压缩气体的气流的流通阻力变大,因此,通过该整流部件之间的压缩气体的流速变慢,从喷射材料喷射部朝被加工物喷射的气流的喷射速度变慢,因此加工效率下降。 [0020] This is because, when the interval than 3mm hours rectifying member, the flow resistance of the compressed gas flow is increased, and therefore, the flow speed of the compressed gas between the rectifying member, the injection material from the injection portion toward the workpiece It was jet air ejection speed is slower, so the processing efficiency is lowered. [0021] 并且,上述整流部也可以具有朝向压缩气体的喷射方向而在长边方向扩展的倾斜面。 [0021] Further, the rectifying portion may have an inclined surface facing the compressed gas injection direction expands in the longitudinal direction. 在该情况下,优选倾斜面相对于喷射方向倾斜的倾斜角θ满足0° < θ <3.7°。 In this case, the inclined surface is preferably inclined to the ejection direction of the inclination angle [theta] satisfies 0 ° <θ <3.7 °.

[0022] 这是因为,当θ超过3. 7°时,气流变得过宽从而长边方向的端部的气流的速度变大,加工量增大,因此,无法对喷射材料喷射部的长边方向的宽广区域均勻地进行喷丸加工。 [0022] This is because, when θ exceeds 3. 7 °, the air flow velocity becomes too wide so that an end portion of the gas flow in the longitudinal direction becomes large, the processing amount increases, and therefore, it can not be long ejecting portion for ejecting material direction is a wide area uniformly shot peening.

[0023] 并且,优选上述气体喷射部的开口部的截面积Sl相对于上述喷射材料喷射部的第二流路的截面积S2的截面积比S1/S2满足0. 1 ( S1/S2 ( 0. 4。 [0023] Further, the sectional area of ​​the opening portion Sl is preferable that the cross-sectional area of ​​the gas ejection portion relative to the second flow path of the injection portion of the injection material cross-sectional area S2 satisfy 0.1 ratio S1 / S2 (S1 / S2 (0 4.

[0024] 这是因为,在S1/S2不足0. 1的情况下,喷射速度大幅下降,因此无法得到充分的加工深度。 [0024] This is because, in the case of S1 / S2 is less than 0.1, the ejection speed dropped, so the machining depth can not be obtained sufficiently. 并且,在S1/S2超过0.4的情况下,在混合室产生的用于吸引喷射材料的负压下降,无法进行稳定的喷射。 Further, in the case where the S1 / S2 exceeds 0.4, the mixing chamber for generating negative pressure suction jet material decreases, can not perform stable ejection.

[0025] 本发明还提供一种喷丸加工装置,从喷嘴对被加工物喷射喷射材料,并扫描被加工物或者上述喷嘴,由此对被加工物进行喷丸加工。 [0025] The present invention further provides a shot peening apparatus, to the workpiece from the injection nozzle spray material, and the scanning of the nozzle or the workpiece, whereby the workpiece was subjected to shot peening. 即,喷丸加工装置具有喷嘴和扫描单元,上述喷嘴用于喷射喷射材料,上述扫描单元用于扫描被加工物或者上述喷嘴,上述喷嘴是基于本发明的喷丸加工用喷射喷嘴。 That is, the shot peening apparatus and the scanning unit having a nozzle, the nozzle for injecting the injection material, the scanning unit for scanning the workpiece or the nozzle, the nozzle of the present invention is based on the shot peening jet nozzle.

[0026] 在该情况下,基于本发明的喷丸加工用喷射喷嘴可以使用上述的一个以上的特征或者上述特征的组合。 [0026] In this case, the present invention is based on the shot peening may be used in combination of the one or more feature or features described above with a jet nozzle. 因此,根据本发明的喷丸加工装置,能够起到与本发明的喷丸加工用喷嘴同样的效果。 Thus, the shot peening apparatus according to the present invention, can function with the same shot-peening nozzle effect of the invention.

[0027] 能够参照附图以及以下的详细说明进一步完全地理解发明的上述的以及其他的特征。 [0027] can refer to the accompanying drawings and the following detailed description more complete understanding of the above and other features of the invention.

[0039] 在喷射材料喷射部14形成有第二流路14a,该第二流路14a的与喷射方向X垂直的截面形成为长方形,从混合室13导入的固气二相流在该第二流路1½中流动。 [0039] The second flow passage 14a is formed in the spray material injection portion 14, X and a direction perpendicular to the ejection section of the second flow passage 14a is formed in a rectangular shape from the mixing chamber 13 is introduced into a solid-gas two-phase flow in the second 1½ flow passage. 如图1 (C) 所示,第二流路14a的长方形截面的长边形成为其方向与第一流路Ila的长方形截面的长边方向一致,且第二流路14a的长方形截面的长边的长度与第一流路Ila的长边的长度大致相同。 Consistent with the longitudinal direction of the rectangular cross section in FIG. 1 (C), the long sides of the rectangular cross section 14a of the second flow path is formed for the direction of the first flow passage Ila, and a long side of the rectangular cross section 14a of the second flow path the length of a long side of the first flow passage with substantially the same Ila. 短边比开口部lib的短边长。 The short side longer than the shorter of the opening portion lib. 当从喷射口侧观察第二流路1½时,形成为长边相等且短边短的第一流路Ila配置在中央的结构。 When viewed from the second flow path 1½ ejection opening side is formed short and the short side of the first flow path structure disposed on the central Ila long side equal.

[0040] 能够使用第一实施方式的喷嘴10以下述的方式进行喷丸加工。 [0040] The first embodiment can be used for shot peening nozzles 10 in the following manner. 当从压缩气体供给装置朝气体喷射部11供给压缩气体时,所供给的压缩气体在第一流路Ila中流动。 When supplying the compressed gas from the compressed gas supply means toward the gas ejection portion 11, the flow of the compressed gas supplied in the first flow path Ila. 此时,压缩气体的气流具有如下的速度分布:中央部的流速快,且随着朝向长边方向的外侧而流速变慢。 At this time, the compressed gas has a flow velocity distribution: Fast Flow central portion, and with the longitudinal direction toward the outside of the slow flow rate.

[0041] 当压缩气体的气流到达形成于气体喷射部11的开口部lib的整流部20时,压缩气体的气流由整流部件21的整流面21a引导,压缩气体的气流在长边方向扩展,在长边方向被整流成均勻的速度分布。 [0041] When the stream of the compressed gas stream reaches formed in 20, compressed gas stream is guided by the rectifying surface rectifying member 21a in the gas injection opening portion lib 11 of the rectifier unit, the compressed gas in the longitudinal direction of extension, in longitudinal direction is rectified into a uniform velocity profile.

[0042] 当从气体喷射部11的前端朝混合室13喷射整流后的压缩气体时,混合室13内成为负压,从而从供给口12导入喷射材料。 [0042] When the gas injection from the distal end portion 11 toward the mixing chamber 13 the compressed gas injection rectified, negative pressure within the mixing chamber 13, introduced from the supply port 12 so that the injection material. 喷射材料乘着整流后的压缩气体的气流被混合, 从而形成在长边方向具有均勻的速度分布、且喷射材料的密度均勻的固气二相流。 Compressed gas stream after the injection material riding rectifier are mixed to form a uniform rate of distribution in the longitudinal direction, and the density of the material injected uniform solid-gas two-phase flow.

[0043] 在混合室13中形成的固气二相流被导入喷射材料喷射部14的第二流路14a。 [0043] The injected material is introduced into the second flow path 14 of the injection portion 14a in the solid-gas two-phase flow in the mixing chamber 13 is formed. 此处,由于气体喷射部11的开口部lib和第二流路1½具有图1 (C)所示的关系,因此,在混合室13中形成的固气二相流的流动不会在长边方向变得紊乱,能够以在长边方向保持均勻的速度分布的状态被喷射至被加工物。 Here, since the gas injection portion and the second flow path opening portion lib 1½ 11 having the relationship shown in FIG. 1 (C), therefore, the flow of the solid-gas two-phase flow formation in the mixing chamber 13 is not in the longitudinal direction become disordered state can maintain a uniform velocity distribution in the longitudinal direction of the workpiece to be sprayed. 通过使喷嘴10相对于被加工物在短边方向相对移动,能够对喷射材料喷射部14的长边方向的宽广区域均勻地进行喷丸加工。 For the moving direction of the workpiece relative to the short side, can be a wide area of ​​the longitudinal direction of the spray material injection portion 14 is peened by the nozzle 10 uniformly phase. 由此,能够扩宽一次能够喷丸加工的宽度,因此能够提高喷丸加工的加工效率。 Thus, one capable of widening the range of the shot peening, it is possible to improve processing efficiency peened.

[0044] 由于在混合室13中形成的固气二相流直接被导入第二流路14a,因此,固气二相流在第二流路的内部扩展并与内壁碰撞的情况变少,能够防止第二流路磨损、损伤的情况。 [0044] Since the solid-gas two formed in the mixing chamber 13 directly phase flow is introduced into the second flow passage 14a, and therefore, the internal solid-gas two-phase flow and the second flow path extended in the case of a collision of the inner wall is reduced, can be a second flow path to prevent wear and tear, damage situation. 此外,由于喷射材料不会与整流部21碰撞,因此也不会出现整流部21磨损、损伤的情况。 Further, since the injected material does not collide with the rectifying portion 21, and therefore the case of rectifier 21 does not wear, damage occurs.

[0045] 以下,对使用本发明的喷射喷嘴10进行的喷丸加工试验进行说明。 [0045] In the following, the test shot peening jet nozzle 10 of the present invention will be described. 另外,本发明的实施方式并不限定于以下的各个试验例。 Further, embodiments of the present invention is not limited to each of the following test examples.

[0046](试验例1) [0046] (Test Example 1)

[0047] 在本试验例中,调查整流部件21的配置对喷丸加工状态造成的影响。 [0047] In this test example, shot peening impact on the state of investigation caused rectifying member 21 is disposed.

[0048] 使用长边的宽度D分别为D = 18mm和D = 15mm的喷嘴10进行平板试样的喷丸加工试验,在利用各个喷嘴10进行喷丸加工后,测定长边方向的加工深度的线轮廓,并判断喷丸加工的好坏。 [0048] The use of longer-side width D of D = 18mm, respectively, and D = 15mm nozzle plate 10 for shot peening test specimen, after use for shot peening each nozzle 10, measured in the longitudinal direction of the machining depth line profile, and determines the quality of the shot peening.

[0049] 对于整流部件21,使用横截面的形状形成为宽度为1mm、长度为IOmm的直角三角形状的2个整流部件21,并分别以斜边位于外侧的方式配置。 [0049] For the rectifying member 21, with a cross-sectional shape has a width of 1mm, a length of a right triangle IOmm two rectifying member 21, respectively, and located outside the hypotenuse arranged.

[0050] 图2中示出使用长边的宽度D为18mm的喷嘴10,并使邻接的整流部件21的间隔B为2mm、3mm的情况下的加工深度的线轮廓。 In [0050] Figure 2 illustrates the use of the long sides of the width D of the nozzle 10 to 18mm, and spaced adjacent commutator member B 21 is 2mm, the contour lines in the case where the machining depth of 3mm.

[0051 ] 在使整流部件21的间隔B为3mm的情况下,能够进行加工深度被收纳在5〜10 μ m 的范围的均勻的喷丸加工。 [0051] In the rectification member B 21 is spaced by 3mm, the depth of machining can be housed in a range of 5~10 μ m uniform shot peening.

[0052] 另一方面,在使整流部件21的间隔B为2mm的情况下,在与整流部件21之间对应的区域加工量变小,无法进行均勻的喷丸加工。 [0052] On the other hand, when the interval B rectifying member 21 is 2mm in the case, the region between the processing corresponding to the rectifying member 21 becomes small, not uniform shot peening. 这种情况考虑是由于下述原因造成的:当整流部件21的间隔B变小时,压缩气体的气流的流通阻力变大,因此,通过该整流部件21之间的压缩气体的流速变慢,从喷射材料喷射部朝被加工物喷射的气流的喷射速度变慢,因此加工效率下降。 This is due to the consideration of the following reason: when the resistance of the flow rectifying member 21 B interval becomes small, the compressed gas flow is increased, and therefore, by compressing the gas rectifying member 21 between the slow flow rate, from ejecting portion ejecting material is ejected toward the workpiece ejection velocity gas flow is slower, so the processing efficiency is lowered.

[0053] 表1中示出使用长边的宽度D为18mm的喷嘴10、并使整流部件21的间隔B为2〜 5mm的情况下的喷丸加工的结果,以及使用长边的宽度D为15mm的喷嘴10、并使整流部件21的间隔B为3mm的情况下的喷丸加工的结果。 [0053] Table 1 shows the width D of the long side of 18mm using the nozzle 10, and the rectifying member is spaced B 21 results in the case where shot peening 2~ 5mm, and the width D of the long side is used 15mm nozzle 10, and the rectifying member is spaced B 21 results in the case where shot peening of 3mm. 在喷嘴10的长边的宽度为18mm和15mm 的任一种情况下,在邻接的整流部件21的间隔B在3mm以上的情况下都能够进行良好的喷丸加工,从而确认了优选邻接的整流部件21的间隔在3mm以上。 In the longer-side width of the nozzle 10 is 18mm 15mm and in any case, in the interval B adjacent commutator member 21 can be a good shot peening under the above circumstances 3mm, thus confirming preferably adjacent commutator member 21 is spaced less than 3mm.

[0056](试验例2) [0056] (Test Example 2)

[0057] 调查整流部件21的大小对喷丸加工状态造成的影响。 [0057] Investigation rectifying member 21 affects the size of the state caused by shot peening. 使用长边的宽度为18mm的喷嘴10,以与试验例1同样的条件进行喷丸加工试验,并判断喷丸加工的好坏。 Width of 18mm using a long side of the nozzle 10, to perform shot peening test was the same conditions as in Test Example 1, and determines quality peened. 如图3所示,作为整流部件21,使用横截面的形状形成为宽度为2mm、长度为IOmm的等腰三角形状的整流部件21,并将该整流部件21配置在长边的中央。 As shown in FIG. 3, as the rectifying member 21, using cross-sectional shape has a width of 2mm, a length of the isosceles triangle IOmm rectifying member 21, and the rectifying member 21 disposed in the center of the long sides.

[0058] 在本试验例的整流部件21中,整流部件21的下游几乎未被加工。 [0058] In the rectifying section 21 in this test example, the downstream rectifying member 21 is hardly processed. 这种情况考虑是由于下述原因造成的:当整流部件21的宽度超过Imm时,整流部件21的下游处的气流的速度下降,因此无法达成均勻的速度分布,并且整流部件21的下游处的喷射材料的浓度变得稀薄。 This is due to the consideration of the following reason: When the width exceeds Imm, rectifying member 21, the air flow velocity downstream rectifying member 21 at a drop, and therefore unable to reach a uniform velocity profile, and the downstream rectifying member 21 concentration of the injection material becomes thin. 由此,确认了优选整流部件21的宽度在Imm以下。 Thus, it was confirmed the following preferred width Imm rectifying member 21.

[0059](试验例3) [0059] (Test Example 3)

[0060] 调查整流部件21的形状对喷丸加工状态造成的影响。 [0060] Investigation rectifying member 21 affects the shape of the state caused by shot peening. 使用长边的宽度为18mm的喷嘴10,以与试验例1同样的条件进行喷丸加工试验,并判断喷丸加工的好坏。 Width of 18mm using a long side of the nozzle 10, to perform shot peening test was the same conditions as in Test Example 1, and determines quality peened. 作为整流部件21,使用如图4(A)所示的横截面的形状形成为菱形、椭圆形的1个整流部件21,并将该整流部件21配置在长边的中央。 Shape 21, a rectifying member as shown in FIG 4 (A) shown in cross section is formed as a rectifying member diamond, oval 21, and the rectifying member 21 disposed in the center of the long sides. 这些形状的整流部件21在喷射方向具有宽度变窄的部分。 The rectifying member 21 has a shape narrowed portion in the width direction of the ejection.

[0061] 在截面形状为菱形的情况下,加工深度会产生偏差,并且,如图4 (B)所示,加工部与未加工部之间的边界呈波状地紊流,无法进行良好的喷丸加工。 [0061] In the case where the sectional shape of a rhombus, the machining depth deviation is generated, and FIG. 4 (B), the boundary portion between the processing section and the wavy unprocessed turbulent manner, can not be sprayed well pills processing. 这种情况考虑是由于以下原因造成的:通过存在宽度变窄的部分,在整流部件21的下游产生了涡流。 This is due to the consideration of the following reasons: by narrowing the width of the portion present in the downstream rectifying member 21 is a vortex. 由此能够确认:如果截面形状形成为像三角形、半椭圆、半圆等那样越朝向压缩气体的喷射方向宽度越宽的形状,则不会在整流部件21的下游产生涡流,能够将压缩气体的气流整流成均勻的速度分布,能够对宽广区域均勻地进行喷丸加工,因此是优选的。 Whereby it was confirmed that: if the ejection direction of the sectional shape like a triangle, a semi-elliptical, semi-circular, etc. as the width of the compressed gas toward the wider shape, no vortex is generated downstream of the rectifying member 21, the gas stream can be compressed rectified into a uniform velocity profile, shot peening can be performed uniformly on a wide area, and therefore is preferable.

[0062](试验例4) [0062] (Test Example 4)

[0063] 调查(A)加工深度以及⑶产生负压与气体喷射部11的开口部lib的截面积Sl 相对于喷射材料喷射部14的第二流路14a的截面积S2的截面积比S1/S2之间的关系。 [0063] Investigation (A) ⑶ machining depth and cross-sectional area Sl negative pressure generating portion lib of the gas injection opening portion 11 with respect to the cross-sectional area S2 of the second flow passage portion 14a of the injection material 14 injected ratio S1 / the relationship between S2. 如图5 (A)所示,在S1/S2不足0. 1的情况下,喷射速度大幅下降,因此无法得到充分的加工深度。 FIG 5 (A), in case of S1 / S2 is less than 0.1, the ejection speed dropped, so the machining depth can not be obtained sufficiently. 并且,如图5(B)所示,在S1/S2超过0.4的情况下,在混合室13中产生的用于吸引喷射材料的负压下降,无法实现稳定的喷射。 And, FIG. 5 (B), in the case where the S1 / S2 exceeds 0.4, the spray material in the negative pressure for sucking in the mixing chamber 13 drop generated, can not be stabilized ejection is accomplished. 由此能够确认,优选上述截面积比S1/S2满足0. 1 彡S1/S2 彡0. 4。 Thus it was confirmed that, preferably, the cross-sectional area satisfies 0.1 San S1 / S2 ratio of 0.4 San S1 / S2.

[0064] 整流部件21的个数、配置间隔等能够根据作为目标的加工宽度适当选定。 [0064] The number of rectifying members, intervals like 21 can be appropriately selected according to the machining width of a target.

[0065] 根据本发明的喷嘴10,在气体喷射部11的开口部11b,能够利用整流部20(整流部件21)使压缩气体的气流在长方形截面的长边方向扩展。 [0065] The nozzle 10 of the present invention, the opening portion 11b of the gas ejection portion 11, a rectifying unit 20 can be utilized (rectifying member 21) so that the compressed gas stream is expanded in the longitudinal direction of the rectangular cross section. 由此,能够使在长边方向被整流成均勻的速度分布的压缩气体和从供给口12供给的喷射材料在混合室13中混合而形成固气二相流,并将该固气二相流导入喷射材料喷射部14。 This makes it possible in the longitudinal direction is rectified into a uniform velocity distribution of the compressed gas and spray material supplied from the supply port 12 are mixed in the mixing chamber 13 is formed in the solid-gas two-phase flow, and the solid-gas two-phase flow injection unit 14 into the spray material. 由于该固气二相流被整流成在长边方向具有均勻的速度分布,并且喷射材料的密度变得均勻,因此能够对喷射材料喷射部14的长边方向的宽广区域均勻地进行喷丸加工。 Since the solid-gas two-phase flow is rectified into a uniform velocity profile, and the injection density of the material becomes uniform, wide area can be injected to the longitudinal direction of the material ejection portion 14 uniformly in the longitudinal direction of the shot-peened . 由此,一次能够进行喷丸加工的宽度变宽, 因此能够提高喷丸加工的加工效率。 Accordingly, a width can be widened shot peening, shot peening can be improved machining efficiency.

[0066] 并且,由于在形成固气二相流之前对压缩气体的流动进行整流,在混合室13中形成的固气二相流直接被导入配置在相同的长边方向的第二流路14a,因此,固气二相流在第二流路14a的内部扩展并与内壁碰撞的情况变少,能够防止第二流路Ha磨损、损伤的情况。 [0066] Further, since the formation of the solid-gas two flow rectifying the compressed gas stream prior phase, solid-gas two formed in the mixing chamber 13 directly phase flow is introduced into the second flow path disposed in the same longitudinal direction 14a Therefore, the solid-gas two-phase flow in the second flow passage inside the case extension 14a and the inner wall of the case of a collision is reduced, the second flow path can be prevented Ha abrasion damage. 此外,由于喷射材料不会与整流部21碰撞,因此整流部21不会磨损、损伤。 Further, since the injected material does not collide with the rectifying portion 21, so rectifier 21 will not wear and damage. 由此,能够实现耐久性高的喷嘴10。 Accordingly, it is possible to achieve a high durability of the nozzle 10.

8[0067] 图6示出本发明的第二实施方式的喷丸加工用喷射喷嘴10的长边方向的剖视图。 Shot peening 8 [0067] FIG. 6 shows a second embodiment of the present invention is cross-sectional view of the longitudinal direction of the jet nozzle 10. 该第二实施方式的喷嘴10与图1 (b)所示的第一实施方式的喷嘴10的不同点在于,整流部20具有朝向压缩气体的喷射方向而在长边方向扩展的倾斜面22。 The nozzle 10 of the second embodiment of FIG. 1 (b) is different from the first embodiment of the nozzle 10 shown in that embodiment, the rectifying section 20 having the ejection direction of the gas toward the compression and expansion in the longitudinal direction of the inclined surface 22. 在气体喷射部11的第一流路Ila中流动的压缩气体的气流由倾斜面22朝长边方向外侧引导而扩展,因此,与上述第一实施方式同样,能够对喷射材料喷射部14的长边方向的宽广区域均勻地进行喷丸加工。 In the gas stream of the compressed gas injection portion of the first flow passage 11 flows toward the longitudinal direction Ila by the inclined surface 22 and the outer guide extension, and therefore, the above-described first embodiment, it is possible for a long side portion 14 of the injection material ejection direction is a wide area uniformly shot peening. 此处,优选倾斜面22相对于喷射方向倾斜的倾斜角θ满足0° < θ < 3.7°。 Here, preferably the inclined surface 22 is inclined with respect to the injection direction the inclination angle [theta] satisfies the 0 ° <θ <3.7 °. 当θ 超过3. 7°时,气流过宽从而导致长边方向的端部的气流的速度变大,加工量增大,因此无法对长边方向的宽广区域均勻地进行喷丸加工。 When θ exceeds 3. 7 °, the air flow rate is too wide leading end portion of the gas flow in the longitudinal direction becomes large, the processing amount increases, and therefore can not wide area of ​​the longitudinal direction of the shot peening uniformly.

[0068] 以上对本发明的实施方式进行了说明,但是,上述说明只是示例,并不对本发明进行限定。 [0068] Although the embodiment of the present invention has been described, however, the foregoing description is exemplary and not to limit the invention. 本领域技术人员可以清楚,不会脱离附加的权利要求所示的本发明的主旨和范围就能够得到许多变更例或变形例。 Those skilled in the art can understand, the spirit and scope of the claimed invention shown without departing from the appended claims many variations can be obtained embodiment or modification.
