Description
本發明係關於用於管端部之擴口形成加工裝置之夾管裝置，具體而言，係關於連接作為空調裝置之冷媒管等使用之管材之情形，以擴口形成工具形成設於管材端部之擴口形狀部上所必須之夾管裝置。The present invention relates to a pinch device for a flare forming processing device for a pipe end portion, and more particularly to a pipe material used for connecting a refrigerant pipe or the like as an air conditioner, and is formed at a pipe end by a flare forming tool. The pinch device necessary for the flared shape of the part.
先前，將管材(主要為銅管)之端部擴徑成圓錐形以形成擴口上，係使用夾管裝置與手動或電動之擴口成形工具所構成之擴口形成加工裝置。如圖1所示，藉由將擴口成形工具之偏心錐5壓向夾持於夾管裝置之管材4之端部並使之旋轉，進行管材4之擴口形成加工。偏心錐5其旋轉中心相對於主軸之軸線傾斜設置，即使主軸旋轉，偏心錐5之頂點亦一直位於主軸之軸線上。Previously, the end of the pipe (mainly copper pipe) was expanded to a conical shape to form a flare, and a flaring forming device was formed using a pinch device and a manual or electric flare forming tool. As shown in Fig. 1, the flaring forming of the pipe 4 is performed by pressing the eccentric cone 5 of the flare forming tool against the end of the pipe 4 held by the pinch device and rotating it. The center of rotation of the eccentric cone 5 is inclined with respect to the axis of the main shaft, and even if the main shaft rotates, the apex of the eccentric cone 5 is always located on the axis of the main shaft.
先前之夾管裝置之一例如圖10所示。具有一方之端部藉由支點7自由開閉地結合之2種分割方式之夾具1。夾具1由上夾持構件1a與下夾持構件1b構成，於上夾持構件1a之另一端軸支有夾持螺栓，於下夾持構件1b之另一端軸支有連桿。管材4之擴口形成加工時，藉由旋轉把手8使夾持螺栓螺合於未圖示之緊固螺母，將管材4以上夾持構件1a及下夾持構件1b緊固。One of the previous pinch devices is shown in Figure 10. A jig 1 having two types of division methods in which one end portion is freely opened and closed by a fulcrum 7 is provided. The jig 1 is composed of an upper holding member 1a and a lower holding member 1b, a holding bolt is axially supported at the other end of the upper holding member 1a, and a link is pivotally supported at the other end of the lower holding member 1b. When the flared portion of the pipe 4 is formed, the clamp bolt 8 is screwed to a fastening nut (not shown) to fasten the pipe 4 and the lower clamp member 1a and the lower clamp member 1b.
又，管材4之擴口形成加工結束後放鬆把手8，如二點鏈線所示，藉由倒向側方以開放上夾持構件1a與下夾持構件1b。另，符號19為管材之軸向之定位用止動器，定位後可從管端位置退出。Further, after the flaring forming of the pipe 4 is completed, the handle 8 is released, and as shown by the two-dot chain line, the upper holding member 1a and the lower holding member 1b are opened by the reverse side. Further, reference numeral 19 is a stopper for positioning the axial direction of the pipe, and can be withdrawn from the pipe end position after positioning.
另，前述上下夾持構件1a、1b中，如圖10及圖11所示，上下襯墊3a、3b分別可裝卸地藉由螺絲14固定，且一體設置於上下夾持構件1a、1b，該上下襯墊3a、3b係具有於內面夾持管材4之夾持部2a、與位於端面之擴口形成用之圓錐面2b。Further, in the upper and lower holding members 1a and 1b, as shown in Figs. 10 and 11, the upper and lower pads 3a and 3b are detachably fixed by screws 14 and integrally provided to the upper and lower holding members 1a and 1b. The upper and lower pads 3a and 3b have a sandwiching portion 2a for sandwiching the tube 4 on the inner surface and a conical surface 2b for forming a flare at the end surface.
管端部之擴口形成加工，係於夾具1***欲形成擴口之管材4之端部並推抵至止動器19，旋轉把手8以緊固上下夾持構件1a、1b，為電動工具之情形，藉由使馬達旋轉，一面使主軸旋轉一面藉由推進螺桿向軸向推壓。藉此偏心錐5一面偏心一面旋轉，向管材4之端部施加推壓力，於管材4之端部形成擴口。The flared end portion of the pipe is formed by inserting the clamp 1 into the end of the pipe 4 to be flared and pushing it against the stopper 19, and rotating the handle 8 to fasten the upper and lower clamp members 1a, 1b as a power tool In this case, by rotating the motor, the spindle is rotated while pushing the screw in the axial direction. Thereby, the eccentric cone 5 is eccentrically rotated, and a pressing force is applied to the end portion of the pipe member 4 to form a flare at the end portion of the pipe member 4.
此時，上下一對之襯墊3a、3b彼此於軸心方向不產生階差，且沿分割面6垂直於軸心之方向彼此不產生芯偏移地固定於夾具1，擴口形成加工中上下襯墊3a、3b之端面角部宜形成完全之圓錐面2b。At this time, the pair of upper and lower pads 3a, 3b do not have a step difference in the axial direction, and are fixed to the jig 1 without causing a core offset along the direction perpendicular to the axis of the dividing face 6, and the flaring is formed in the process. It is preferable that the end face corner portions of the upper and lower pads 3a, 3b form a complete conical surface 2b.
但，前述先前之夾管裝置中，夾持管時於管軸方向不存在充分固定夾具1之機構，存在因擴口形成加工時之推壓力於上下襯墊3a、3b產生前述軸向之階差T(圖13A)之問題。另，亦存在上下襯墊3a、3b於管材4之半徑方向偏移之前述芯偏移之問題。However, in the above-described conventional pinching device, there is no mechanism for sufficiently fixing the jig 1 in the tube axis direction when the tube is clamped, and the above-mentioned axial order is generated in the upper and lower pads 3a, 3b due to the pressing force at the time of forming the flare. The problem of the difference T (Fig. 13A). Further, there is also a problem that the upper and lower pads 3a, 3b are offset by the core in the radial direction of the tube 4.
前述芯偏移雖由支點7與上下夾持構件1a、1b之半圓弧之中心間距離R決定，但支點7之軸徑與孔徑存在一定程度之間隙，因上下襯墊3a、3b沿管材4被夾持，故較不易產生。至於階差，從產生頻度之面來看亦成為問題，若產生階差則如圖13A及圖13B所示，擴口形狀將不良。The core offset is determined by the distance R between the fulcrum 7 and the center of the semicircular arc of the upper and lower clamping members 1a, 1b, but the shaft diameter of the fulcrum 7 and the aperture have a certain degree of clearance, because the upper and lower pads 3a, 3b are along the pipe. 4 is clamped, so it is less likely to be produced. As for the step difference, it also becomes a problem from the viewpoint of the frequency of occurrence. If a step is generated, as shown in Figs. 13A and 13B, the flared shape is defective.
上下襯墊3a、3b之階差，如前所述直接反映於管材4之擴口形狀。雖一定程度內之階差不影響氣體洩漏，但存在即使因接頭之緊固不足等施工上之問題之其他因素而產生氣體洩漏之情形，其原因有時亦疑為擴口形狀不良，從查明真正之問題原因來看，亦要求上下襯墊3a、3b之不產生階差之夾管裝置。The step difference between the upper and lower pads 3a, 3b is directly reflected in the flared shape of the tube 4 as described above. Although the step difference within a certain degree does not affect the gas leakage, there is a case where a gas leak occurs even due to other factors such as insufficient fastening of the joint, and the cause is sometimes suspected to be a bad shape of the flare. In view of the real problem, it is also required that the upper and lower pads 3a, 3b do not have a stepped pinch device.
作為前述階差之改良對策，先前如圖11及圖12所示，於上夾持構件1a設置突片9，於下夾持構件1b設置前述突片9之嵌合部10，夾持管材4時前述突片9與嵌合部10嵌合，防止管軸心方向之階差之產生。As a countermeasure for improvement of the above-described step, as shown in FIGS. 11 and 12, a tab 9 is provided on the upper holding member 1a, and a fitting portion 10 of the tab 9 is provided in the lower holding member 1b, and the tube 4 is sandwiched. At this time, the protruding piece 9 is fitted to the fitting portion 10 to prevent the occurrence of a step in the axial direction of the tube.
但，於突片9與嵌合部10為防止嵌合時之干擾而設有間隙(圖12之P及Q)，由於上下襯墊3a、3b於擴口形成加工中於圖12之箭頭F方向會受到推壓力，故上夾持構件1a會沿管軸方向朝箭頭F方向偏移嵌合部10之前述間隙P。即使為盡量減少前述間隙P而設定突片9及嵌合部10之尺寸，但因尺寸公差之累積終將產生0.2mm左右之階差，難以完全消除階差。However, the gap between the protruding piece 9 and the fitting portion 10 to prevent interference during fitting is provided (P and Q in Fig. 12), and the upper and lower pads 3a and 3b are formed in the flaring forming process in the arrow F of Fig. 12 Since the direction is pressed, the upper holding member 1a is displaced in the direction of the arrow F in the direction of the arrow axis by the aforementioned gap P of the fitting portion 10. Even if the size of the protruding piece 9 and the fitting portion 10 is set to minimize the gap P, the accumulation of the dimensional tolerance will eventually result in a step of about 0.2 mm, and it is difficult to completely eliminate the step.

以下，對本發明之夾管裝置之第1實施形態使用圖式進行說明。Hereinafter, the first embodiment of the pinch tube device of the present invention will be described with reference to the drawings.
因圖1~圖4所示之本實施形態之夾管裝置與圖10~圖12所說明之先前技術之夾管裝置，關於擴口形成加工用之夾持機構為基本同一之構成，故以下對兩者之構成之不同點進行說明。另，共通零件以同一符號表示。另，表示夾持構件、襯墊等之「上下」之表達係為明確零件相互之位置關係者，並非表示實際配置上之空間位置，並非限制本裝置之安裝狀態者。Since the pinching device of the present embodiment shown in FIGS. 1 to 4 and the pinching device of the prior art described with reference to FIGS. 10 to 12 have substantially the same configuration for the grooving forming process, the following The differences between the two components will be explained. In addition, common parts are denoted by the same symbol. In addition, the expression "upper and lower" of the grip member, the pad, and the like is a clear positional relationship between the components, and does not indicate the spatial position of the actual arrangement, and does not limit the mounting state of the device.
由一對夾持構件1a、1b所構成之點相同，該一對夾持構件1a、1b係夾持管材4之端部外周面之整個面，分別安裝有成對為大致圓筒形狀之切半狀之上下襯墊3a、3b，但於本實施形態之夾管裝置中在一對夾持構件1a、1b之夾持管時之配合面6a、6b，於下夾持構件1b側之配合面6b設有突起11，於上夾持構件1a側之配合面6a設有夾持管時收容前述突起11之凹部12，此點與先前技術之夾管裝置不同。The points formed by the pair of holding members 1a and 1b are the same, and the pair of holding members 1a and 1b sandwich the entire outer peripheral surface of the end portion of the pipe 4, and are respectively cut in pairs in a substantially cylindrical shape. In the pinch device of the present embodiment, the mating faces 6a and 6b of the pair of holding members 1a and 1b are clamped on the lower holding member 1b side. The surface 6b is provided with a projection 11 which accommodates the recess 12 of the projection 11 when the fitting surface 6a on the side of the upper holding member 1a is provided with a holding tube, which is different from the prior art pinching device.
即，本實施形態之前述構成，係將延長下夾持構件1b之一部分設置之突起11之與管材之軸垂直之平面13a，沿與下夾持構件1b中下襯墊3b之階差形成面2c之抵接面13b同一面上設置。突起11、凹部12、平面13a及襯墊抵接面13b之位置關係如圖5及圖6所示。In other words, in the above-described configuration, the flat surface 13a perpendicular to the axis of the tube of the projection 11 provided in a portion of the lower holding member 1b is extended, and the surface is formed along the step of the lower liner 3b in the lower holding member 1b. The abutting surface 13b of 2c is disposed on the same surface. The positional relationship between the projection 11, the recess 12, the flat surface 13a, and the spacer abutting surface 13b is as shown in Figs. 5 and 6 .
藉由前述構成，於管端部實施擴口形成加工時，管材4藉由上下襯墊3a、3b夾持，偏心錐5其自身繞偏心軸旋轉，此外藉由該偏心軸一面繞中心軸旋轉且向中心軸方向推壓，偏心錐5之圓錐斜面沿管材4之端部圓周面旋轉，且於管端部施加軸向之加工之推壓力。因藉由該推壓力，上襯墊3a之階差形成面2c及下襯墊3b之階差形成面2c與位於同一平面上之平面13a及抵接面13b抵接，故不於上下襯墊3a、3b產生管軸方向之階差。According to the above configuration, when the flaring forming process is performed at the end of the pipe, the pipe 4 is held by the upper and lower linings 3a and 3b, and the eccentric cone 5 itself rotates around the eccentric shaft, and the eccentric shaft rotates around the central axis. Further, it is pressed in the direction of the central axis, and the tapered slope of the eccentric cone 5 is rotated along the circumferential surface of the end portion of the pipe 4, and the pressing force of the axial machining is applied to the end portion of the pipe. Because of the pressing force, the step forming surface 2c of the step forming surface 2c and the lower pad 3b of the upper pad 3a abuts against the flat surface 13a and the abutting surface 13b on the same plane, so that the upper and lower pads are not provided. 3a, 3b produce a step difference in the direction of the tube axis.
如前述說明，第1實施形態中於下夾持構件1b之配合面6b之一部分形成突起11，將突起11之平面13a作為與上襯墊3a之階差形成面2c之抵接面。前述平面13a與下夾持構件1b之下襯墊3b之抵接面13b配設於同一面上，其結果，擴口加工時上下之襯墊3a、3b一併抵接於作為下夾持構件1b之襯墊抵接面之同一平面13a及13b，可防止階差之產生。As described above, in the first embodiment, the projection 11 is formed in one of the mating faces 6b of the lower holding member 1b, and the flat surface 13a of the projection 11 serves as a contact surface with the step forming surface 2c of the upper spacer 3a. The abutting surface 13a of the lower surface of the lower surface of the lower holding member 1b is disposed on the same surface, and as a result, the upper and lower pads 3a, 3b are abutted together as a lower holding member. The same planes 13a and 13b of the pad abutting faces of 1b prevent the generation of the step.
下面，對第2實施形態進行說明。Next, a second embodiment will be described.
本實施形態中作為上下襯墊3a、3b之偏移防止對策，係於上下襯墊3a、3b分別設置銷15及銷孔16。如圖7A及圖7B所示，銷15及銷孔16於上襯墊3a之下面與下襯墊3b之上面分設1個，合計共設2對。In the present embodiment, as the countermeasure against the offset of the upper and lower pads 3a and 3b, the pin 15 and the pin hole 16 are provided in the upper and lower pads 3a and 3b, respectively. As shown in FIG. 7A and FIG. 7B, the pin 15 and the pin hole 16 are provided in the lower surface of the upper spacer 3a and the upper surface of the lower spacer 3b, and a total of two pairs are provided.
因可將銷15及銷孔16之直徑設定為間隙0.1mm以下，故可將階差尺寸抑制在0.1mm以下，可防止實質性階差之產生。另，如圖8所示，於銷15之端面外周部及銷孔16之緣設有倒角部17，夾持管時銷15之端面外周部不干涉銷孔16之緣，易於嵌合。本實施形態中，雖代替前述突起11與開口部12設有2對銷15及銷孔16，但亦可與前述突起11與開口部12並設銷15及銷孔16。Since the diameter of the pin 15 and the pin hole 16 can be set to a gap of 0.1 mm or less, the step size can be suppressed to 0.1 mm or less, and the generation of a substantial step can be prevented. Further, as shown in Fig. 8, a chamfered portion 17 is provided on the outer peripheral portion of the end surface of the pin 15 and the pin hole 16, and the outer peripheral portion of the end surface of the pin 15 does not interfere with the edge of the pin hole 16 when the tube is pinched, and the fitting is easy. In the present embodiment, the pair of pins 15 and the pin holes 16 are provided instead of the protrusions 11 and the opening portion 12. However, the pins 15 and the pin holes 16 may be provided in parallel with the protrusions 11 and the opening portion 12.
本實施形態中，作為一例雖顯示使銷15與對應之銷孔16於夾持管時為同心狀般配置之例，但作為其他實施例亦可如圖9所示，使孔18之直徑大於銷直徑，於夾持管時銷15偏心尺寸S***孔18地配置。藉此可放寬用於嵌合銷15之倒角部17之精度限制。In the present embodiment, as an example, the pin 15 and the corresponding pin hole 16 are arranged concentrically when the tube is clamped. However, as another embodiment, the diameter of the hole 18 may be larger than that shown in FIG. The pin diameter is disposed when the pin 15 is eccentrically dimensioned by the insertion hole 18 when the tube is clamped. Thereby, the precision limit for the chamfered portion 17 of the fitting pin 15 can be relaxed.
如此偏心設置孔18之實施例中，管軸方向之一方之孔18之內壁幾乎接觸銷15之外周部地配置，可防止於上下襯墊3a、3b產生管軸方向之階差。In the embodiment in which the hole 18 is eccentrically disposed, the inner wall of the hole 18 which is one of the tube axis directions is almost in contact with the outer peripheral portion of the pin 15, and the step of the tube axis direction is prevented from being generated in the upper and lower pads 3a, 3b.
雖圖9中只使2處銷結合中之一處偏心，但使兩處銷結合都偏心亦可。Although only one of the two pin combinations is eccentric in FIG. 9, it is also possible to eccentrically combine the two pins.
如前所述，本發明之夾管裝置及使用其之擴口形成加工裝置，可防止擴口形成加工時之上下襯墊之階差之產生，提高管材之擴口形成加工之可靠性。As described above, the pinch tube device of the present invention and the flare forming processing device using the same can prevent the occurrence of the step of the upper and lower liners during the flaring forming process, and improve the reliability of the flaring forming process of the pipe.
