[承受台40] 圖4係直管用之承受台及進給台的說明圖。圖5係半圓凹部及防振部的說明圖。承受台40係垂直地配置主面並在上端部包括半圓凹部42的板，該半圓凹部42係沿著外周支撐比與成為切斷對象物之直管14的軸平行的截面更下側。承受台40係以既定間隔支撐將軸作成橫向之直管14的底面。 切斷手段20之鋸刃22係沿著切斷對象物12的軸，換言之，通過直徑，這成為對開切斷的截面。承受台40係支撐比與切斷手段20之鋸刃22不接觸的此截面更下方。因此，將半圓凹部42形成為是比切斷對象物12之軸更下方(例如數十毫米)，並連接與切斷對象物12之直徑平行之弦的兩端之圓弧狀。在此時，半圓凹部42係以比切斷對象物12之半徑更大的半徑(例如數毫米)進行切削加工。藉此，可對切斷對象物12的底面側(下側)嵌合。[Receiving table 40] FIG. 4 is an explanatory diagram of a receiving table and a feeding table for straight pipes. Fig. 5 is an explanatory diagram of a semicircular recessed portion and a vibration-proof portion. The receiving table 40 is a plate in which the main surface is vertically arranged and includes a semicircular recessed portion 42 at an upper end portion. The semicircular recessed portion 42 is supported along the outer periphery lower than a cross section parallel to the axis of the straight pipe 14 to be cut. The receiving table 40 supports the bottom surface of the straight tube 14 with the shaft formed in a horizontal direction at predetermined intervals. The saw blade 22 of the cutting means 20 is along the axis of the cutting object 12, in other words, it has a cross-section cut in half by the diameter. The receiving table 40 supports lower than this section which is not in contact with the saw blade 22 of the cutting means 20. Therefore, the semicircular concave portion 42 is formed below the axis of the cutting object 12 (for example, several tens of millimeters), and is connected to an arc shape of both ends of a chord parallel to the diameter of the cutting object 12. At this time, the semi-circular recessed portion 42 is cut with a radius (for example, several millimeters) larger than the radius of the cutting target 12. Thereby, the bottom surface side (lower side) of the cutting object 12 can be fitted.
包括這種構成之半圓凹部42的承受台40係藉由在比截面更下方接觸橫向地配置軸之切斷對象物12，可支撐成無礙於水平地配置軸之切斷對象物12的對開切斷作業。又，可在進給台60上易於安裝或拆下切斷對象物12。對開切斷之上側的切斷對象物12係位於搭在下側的切斷對象物12之上的狀態，在切斷後可分開地取出。 此外，以承受台40所支撐切斷對象物係即使是角柱，換言之，多角形，亦可切斷。在此情況，沿著多角形之外形形成凹部即可。例如，將四角柱作為切斷對象物，在截面(鋸刃位置)為水平的情況，凹部的形狀係成為等腰直角三角形。又，亦可在承受台40將凹部形成為支撐一個或複數個形狀相同或相異的切斷對象物。The receiving table 40 including the semi-circular recessed portion 42 having such a structure can support the cutting object 12 in which the shaft is arranged horizontally by contacting the cutting object 12 in which the shaft is arranged horizontally below the cross section. Cut job. In addition, the cutting target 12 can be easily attached to or detached from the feeding table 60. The cutting object 12 on the upper side of the split cut is in a state of being placed on the lower cutting object 12 and can be taken out separately after cutting. In addition, the cutting target system supported by the receiving table 40 can be cut even if it is a corner post, in other words, a polygon. In this case, it is sufficient to form the recessed portion along the polygonal shape. For example, when a quadrangular prism is used as a cutting object and the cross section (saw blade position) is horizontal, the shape of the recessed portion is an isosceles right-angled triangle. Moreover, the recessed part may be formed in the receiving stand 40 so that one or several cutting objects of the same or different shape may be supported.
[防振部44] 將切斷對象物12與半圓凹部42嵌合時，在間隙(半圓凹部42係以切斷對象物12之半徑加上數毫米的半徑形成)之設計上，在進退移動或切斷中可能發生晃動。因此，設計防振部44。此防振部44係設置於承受台40的半圓凹部42。防振部44係在半圓凹部42的上兩端，從半圓凹部42向切斷對象物12突出。在將切斷對象物12安裝於半圓凹部42時，防振部44的前端與切斷對象物12的軸之間的距離係設定成與切斷對象物12之半徑一致。這種防振部44係可在對承受台40之半圓凹部42進行切削加工時一體地形成，或在形成半圓凹部42後以覆蓋焊接所形成，或黏接彈性構件等所形成。 這種構成之防振部44係藉將切斷對象物12嵌入承受台40之半圓凹部42的簡易動作，產生密接成夾進切斷對象物12的部位，而可確實地防止進退移動或切斷中之振動。[Anti-vibration part 44] When the cutting object 12 is fitted into the semi-circular recess 42, the gap (the semi-circular recess 42 is formed by the radius of the cutting object 12 plus a radius of several millimeters) is moved forward and backward. Or shaking may occur during cutting. Therefore, the anti-vibration part 44 is designed. The anti-vibration portion 44 is provided in the semi-circular concave portion 42 of the receiving base 40. The anti-vibration portion 44 is attached to the upper ends of the semicircular recessed portion 42 and protrudes from the semicircular recessed portion 42 toward the cutting target 12. When the cutting target 12 is attached to the semicircular recessed portion 42, the distance between the tip of the vibration isolator 44 and the axis of the cutting target 12 is set to match the radius of the cutting target 12. Such a vibration-proof portion 44 may be formed integrally when cutting the semicircular recessed portion 42 of the receiving table 40, or formed by covering and welding after forming the semicircular recessed portion 42, or by bonding an elastic member or the like. The anti-vibration portion 44 having such a structure is provided with a simple operation of inserting the cutting object 12 into the semi-circular recess portion 42 of the receiving table 40 to generate a portion that is tightly sandwiched between the cutting object 12 and prevents the advance or retreat from moving or cutting.

The vibration-proof track 88 having such a structure prevents lateral shaking during the forward and backward movement of the feed table 60 (during the cutting operation), reduces the load of the saw blade 22, suppresses damage or abrasion, and enables efficient cutting. The moving means 80 having such a configuration is capable of automatically and efficiently supplying the cutting target 12 to the cutting means 20 so as to cut efficiently.
[對開切斷壓部90] 切斷後之切斷對象物12係對已對開切斷之下側的切斷對象物12是被固定於承受台40之狀態。另一方面，已對開切斷之上側的切斷對象物12係在搭在已對開切斷之下側的切斷對象物12之上的狀態絲毫未被固定。因此，在本發明係在將對開切斷壓部90安裝於在進給台60所安裝的複數個承受台40之間，從側方支撐切斷後之上側的切斷對象物。 圖13係對開切斷壓部的說明圖，(1)係切斷前的正視圖及正視圖的C－C剖面圖，(2)係切斷中的正視圖及正視圖的D－D剖面圖，(3)係切斷前的正視圖及正視圖的E－E剖面圖。更詳細之對開切斷壓部90的構成係主要的基本構成包括壓板92、導管94、斜坡構件96以及壓板承98。[Parting and cutting pressure part 90] The cutting object 12 after cutting is a state where the cutting object 12 on the lower side of the parting and cutting is fixed to the receiving table 40. On the other hand, the state where the cutting object 12 on the upper side of the halved cut is placed on the cutting object 12 on the lower side of the halved cut is not fixed at all. Therefore, in the present invention, the cut-off cutting pressure portion 90 is mounted between a plurality of receiving tables 40 mounted on the feeding table 60 and supports the cutting object on the upper side after cutting. Fig. 13 is an explanatory diagram of the cut-off pressing part, (1) is a front view before cutting and a cross-sectional view taken along the line CG, and (2) is a front view during cutting and a cross-section taken along the line DD. (3) is a front view before cutting and an E-E cross-sectional view of the front view. In more detail, the configuration of the split-and-cut pressure portion 90 is mainly composed of a pressure plate 92, a duct 94, a slope member 96, and a pressure plate holder 98.
壓板92係作成可***承受台40之間，並是形狀與承受台40大致相同的板。在壓板92的上端，與承受台40之半圓凹部42一樣地形成壓凹部93，但是比半圓凹部42更深，換言之，將連接兩上端的直線設定成位於比以壓板92支撐直管14時之切斷對象物12的軸更上方。這種構成之壓凹部93係在安裝於進給台60上時，在與以承受台40所支撐之直管14的下方之間產生大的間隙而不會接觸。The pressure plate 92 is a plate which can be inserted between the receiving tables 40 and has a shape substantially the same as that of the receiving tables 40. On the upper end of the pressure plate 92, a depression portion 93 is formed in the same manner as the semi-circular depression portion 42 of the receiving table 40, but deeper than the semi-circular depression portion 42. In other words, the straight line connecting the two upper ends is set to be a cut that is greater than that when the straight tube 14 is supported by the pressure plate 92 The axis of the breaking object 12 is further above. The recessed portion 93 having such a configuration, when mounted on the feeding table 60, creates a large gap with the bottom of the straight tube 14 supported by the receiving table 40 without contact.
壓板92係在兩側面的上部設置軸承94。軸承94係經由軸95從兩側面沿著壓板92的主面突出。而且，軸承94之主面係與壓板92之主面正交，換言之，沿著進給台60的進退方向所配置。又，在承受台40的兩側面，設置在安裝壓板92時向軸承94之側面外部突出的缺口49。此缺口49係將長度設定成從承受台40之側面的上端向下方既定深度。此處，缺口49的長度係設定成在安裝壓板92時上端不會從進給台之側面突出的長度。藉此，不會與截面交叉，而不會妨礙切斷作業。 斜坡構件96係安裝於切斷手段20之鋸刃22附近的鋸刃蓋28。斜坡構件96係具有從進給台60之切斷方向的供給側往排出側向上方傾斜的斜面，此斜面係設定於與在切斷前在進給台60所安裝之對開切斷壓部90的軸承94之安裝位置大致相同的高度。The pressure plate 92 is provided with bearings 94 on the upper sides of both sides. The bearing 94 protrudes from both side surfaces along the main surface of the pressure plate 92 via the shaft 95. The main surface of the bearing 94 is orthogonal to the main surface of the pressure plate 92, in other words, it is arranged along the advancing and retreating direction of the feed table 60. In addition, notches 49 are provided on both side surfaces of the receiving base 40 to protrude outside the side surfaces of the bearing 94 when the pressure plate 92 is mounted. This notch 49 is set to a predetermined depth downward from the upper end of the side surface of the receiving table 40. Here, the length of the notch 49 is set to a length at which the upper end does not protrude from the side surface of the feeding table when the pressure plate 92 is attached. Thereby, it does not cross a cross section, and it does not interfere with a cutting operation. The ramp member 96 is attached to a saw blade cover 28 near the saw blade 22 of the cutting means 20. The slope member 96 has an inclined surface inclined upward from the supply side in the cutting direction of the feeding table 60 to the discharging side, and the inclined surface is set to a cut-off pressing portion 90 installed on the feeding table 60 before cutting. The mounting position of the bearing 94 is approximately the same height.
壓板承98係安裝於進給台60的側面之缺口49的下方，係支撐壓板92之兩下端的角部者。壓板承98係軸承94沿著斜坡構件96的斜面向上方移動，且成為從進給台60向上方突出之對開切斷壓部90之兩下端的角部所搭的承受台。 這種構成之對開切斷壓部係在對開切斷後之切斷對象物的側方使壓板92比截面更向上突出並可支撐。又，壓板92係因為在切斷前配置於比截面更下方，所以不在不會與鋸刃22發生干涉下進行切斷作業。 藉此，防止切斷後之切斷對象物的落下，而可確保作業員之安全性。The pressure plate support 98 is installed below the notch 49 on the side of the feeding table 60 and supports the corners of the two lower ends of the pressure plate 92. The pressure plate bearing 98 is a bearing 94 that moves upward along the inclined surface of the slope member 96 and serves as a receiving table formed by corners of the two lower ends of the cut-off cutting pressure portion 90 protruding upward from the feed table 60. The half-cutting pressing portion having such a structure is formed on the side of the cutting object after the half-cutting, so that the pressing plate 92 protrudes upward from the cross section and can be supported. In addition, since the pressing plate 92 is disposed below the cross section before cutting, the cutting operation is not performed without interference with the saw blade 22. Thereby, the object to be cut after the cutting is prevented from falling, and the safety of the operator can be ensured.
[作用] 以下，說明根據該構成之本發明之對開切斷裝置的作用。 在將直管14、彎管16當作切斷對象物12的情況，在進給台60將板狀的承受台40***U字槽63並使用固定螺栓固定。承受台40係具有沿著切斷對象物12之外周的半圓凹部42，並在主面與切斷對象物12之軸正交之方向隔著既定間隔地安裝複數個。進而，將對開切斷壓部90安裝於進給台60。然後，將切斷對象物12固定於承受台40。具體而言，在將切斷對象物12與承受台40之半圓凹部42嵌合後，使在接近開口面之承受台40的主面所設置之固定手段50的手臂54進行轉動移動，而與開口之內部接觸。然後，使用蝶形螺栓53及固定螺栓56，固定手臂54的兩端。[Operation] The operation of the split-off device according to the present invention having this configuration will be described below. When the straight pipe 14 and the bent pipe 16 are regarded as the cutting target 12, the plate-shaped receiving table 40 is inserted into the U-shaped groove 63 on the feeding table 60 and fixed with a fixing bolt. The receiving table 40 has a semicircular recessed portion 42 along the outer periphery of the cutting object 12, and a plurality of receiving portions 40 are attached at predetermined intervals in a direction orthogonal to the axis of the cutting object 12. Further, the half-cutting pressing portion 90 is attached to the feeding table 60. Then, the cutting target 12 is fixed to the receiving table 40. Specifically, after the cutting object 12 is fitted into the semicircular recessed portion 42 of the receiving table 40, the arm 54 of the fixing means 50 provided on the main surface of the receiving table 40 close to the opening surface is rotated to move with Internal contact of the opening. Then, both ends of the arm 54 are fixed using the butterfly bolt 53 and the fixing bolt 56.
接著，藉移動手段80向切斷手段20供給進給台60。藉切斷手段20對切斷對象物12進行對開切斷。切斷手段20所通過之對開切斷壓部90從承受台40的上面向上方突出，而固定切斷對象物12之上側部分。根據以上，可藉對開切斷壓部90支撐上側的切斷對象物12，不會落下，而可確保作業員的安全性。Next, the feeding table 60 is supplied to the cutting device 20 by the moving device 80. The cutting target 20 is cut in half by the cutting means 20. The cut-off cutting pressure part 90 through which the cutting means 20 passes protrudes upward from the upper surface of the receiving table 40, and fixes the upper part of the cutting object 12. According to the above, the cutting object 12 on the upper side can be supported by the cut-off cutting pressure portion 90 without falling, and the safety of the operator can be ensured.
在將具有凸緣之配管或閥18當作切斷對象物12的情況，在將承受台40A之第1板45作為底面並將第2板46設定成垂直之狀態，將閥18的凸緣面載置於第1板45的主面上。進行位置調整成凸緣孔與第1狹縫451一致後，以固定螺栓453固定。藉鏈吊車將承受台40A移至進給台60上，並在底座62上將承受台40A載置成承受台40A之第2板46的主面成為水平。在此時，進行第1板45之螺帽454與進給台60之固定夾具61的固定孔之位置調整，從安裝於閥18之連接面的主面側使固定螺栓68螺合，將承受台40A固定於進給台60。 接著，藉移動手段80向切斷手段20供給進給台60。藉切斷手段20對切斷對象物12進行對開切斷，以切斷後之鋸刃22停在第2狹縫452內的方式使移動手段80停止。When a pipe or valve 18 having a flange is used as the cutting target 12, the flange of the valve 18 is set with the first plate 45 of the receiving table 40A as the bottom surface and the second plate 46 in a vertical state. The surface is placed on the main surface of the first plate 45. After adjusting the position so that the flange hole matches the first slit 451, it is fixed with the fixing bolt 453. The receiving platform 40A is moved to the feeding platform 60 by a chain crane, and the receiving platform 40A is placed on the base 62 so that the main surface of the second plate 46 of the receiving platform 40A becomes horizontal. At this time, the position adjustment of the nut 454 of the first plate 45 and the fixing hole of the fixing fixture 61 of the feeding table 60 is performed, and the fixing bolt 68 is screwed from the main surface side of the connection surface mounted on the valve 18, and will receive The stage 40A is fixed to the feeding stage 60. Next, the feeding table 60 is supplied to the cutting device 20 by the moving device 80. The cutting object 20 is cut in half by the cutting means 20, and the moving means 80 is stopped so that the saw blade 22 after the cutting stops in the second slit 452.
若依據這種對開切斷裝置以及對開切斷方法，可一面移動橫向地配置軸之切斷對象物一面切斷，而可在短時間高效率地進行對開切斷，提高運轉效率。 又，不僅大口徑之配管，即使是具有凸緣之配管或閥等的切斷對象物，亦可易於切斷。According to such a halving and cutting device and a halving and cutting method, it is possible to cut while moving the cutting object in which the shaft is arranged horizontally, and the halt and cutting can be efficiently performed in a short time, thereby improving the operation efficiency. In addition, not only a large-diameter pipe but also a cutting object such as a pipe or valve having a flange can be easily cut.
[變形例] 圖14係變形例之對開切斷裝置的說明圖。 變形例之對開切斷裝置10A係移動手段之架台與進給台的構成和圖1所示之對開切斷裝置10相異。因為其他的構成係相同，所以省略詳細的說明。 移動手段之架台係隔著切斷手段20包括進退方向之供給側的第1架台831與排出側的第2架台832。第1、第2架台831、832係都在上面包括與移動手段80之防振軌道88連續的防振軌道88。 進給台60係採用沿著進退方向排列複數個進給台的構成，圖14所示之進給台係配置第1進給台601與第2進給台602之2台。[Modification] FIG. 14 is an explanatory diagram of a split cutting device according to a modification.
