Description

本発明は、対象物を破砕するための破砕機におけるローターに装着される可動刃を研磨する研磨装置にこの可動刃を保持するための研磨治具に関するものである。 The present invention relates to a polishing jig for holding the movable blade in a polishing apparatus for polishing a movable blade mounted on the rotor in the crusher for crushing Target thereof.

特許文献１、２に示されるように、破砕機に使用される可動刃は、一方向に回転するローターの周面に装着され、このローターを収容するハウジングに固定された固定刃と協働して対象物を破砕する刃物である。この可動刃の刃先縁は、各種の形状があるものの、ローターの軸方向を含む平面に収められており、ローターの回転に伴って可動刃の刃先縁はその全長に亘って固定刃の刃先縁へ同時に到達することになる。この結果、可動刃の刃先縁が同時に剪断力を担う機会が多くなり、対象物を破砕する際に大きな負荷が一度に可動刃に作用し、剪断能力の低下を招くだけでなく、可動刃の寿命を低下させることが問題となっている。同時に破砕の際の騒音も大きくなり、作業環境を悪化させる要因となっている。   As shown in Patent Documents 1 and 2, a movable blade used in a crusher is mounted on a circumferential surface of a rotor rotating in one direction, and cooperates with a fixed blade fixed to a housing accommodating the rotor. Cutting blade to cut the object. Although the cutting edge of this movable blade has various shapes, it is housed in a plane including the axial direction of the rotor, and as the rotor rotates, the cutting edge of the movable blade is the cutting edge of the fixed blade over its entire length Will be reached at the same time. As a result, the cutting edge of the movable blade simultaneously has an increased chance of carrying shear force, and a large load acts on the movable blade at one time at the time of crushing an object, which not only causes a reduction in shearing ability but It is a problem to reduce the life. At the same time, the noise at the time of crushing also increases, which causes the working environment to deteriorate.

本発明において用いる破砕機用刃物は、破砕すべき対象物が投入される投入口１２を有するハウジング１０と、ハウジング１０内で投入口１２の下方に配置されて、軸方向の周りで一方向に回転するローター２０と、ローター２０の周面に対向する位置でハウジング１０に固定された固定刃３０を備えた破砕機に使用される可動刃４０である。 Crusher tool used Oite the present invention includes a housing 10 having an inlet 12 in which the object to be crushed is introduced, it is arranged below the inlet 12 in the housing 10, one about axis direction A movable blade 40 used in a crusher provided with a rotor 20 rotating in a direction and a fixed blade 30 fixed to the housing 10 at a position facing the circumferential surface of the rotor 20.

この可動刃４０はローター２０の外周面に形成した台座２２に装着されてローター２０と共に回転することで固定刃３０との間で対象物を剪断するように構成される。台座２２は、ローター２０の軸方向に沿った平面をなす保持面２３を有する。可動刃４０は、前面、後面、上面、下面および両側面を有する金属体であり、金属体の前面が固定刃３０に対向する逃げ面４１を規定し、金属体の上面がローター２０の回転方向前方に位置するすくい面４２を規定し、金属体の底面が保持面２３に面接合する取付面４３を規定する。   The movable blade 40 is mounted on a pedestal 22 formed on the outer peripheral surface of the rotor 20 and is configured to shear an object with the fixed blade 30 by rotating with the rotor 20. The pedestal 22 has a holding surface 23 which is a plane along the axial direction of the rotor 20. The movable blade 40 is a metal body having a front surface, a rear surface, an upper surface, a lower surface, and both side surfaces, the front surface of the metal body defines a flank 41 facing the fixed blade 30, and the upper surface of the metal body is the rotation direction of the rotor 20. A rake surface 42 located in front is defined, and a bottom surface of the metal body defines a mounting surface 43 to be surface-bonded to the holding surface 23.

可動刃４０は取付面４３を保持面２３に面接させる形で上記台座２２に保持される。すくい面４２と逃げ面４１との間に４０〜５０度の刃先角が形成され、すくい面４２が取付面４３と非平行となる。すくい面４２の前端と逃げ面の前端との間に形成される切刃縁４７が、取付面４３の前端縁に対して傾斜している。   The movable blade 40 is held by the pedestal 22 in such a manner that the mounting surface 43 is brought into contact with the holding surface 23. An edge angle of 40 to 50 degrees is formed between the rake surface 42 and the flank surface 41, and the rake surface 42 is not parallel to the mounting surface 43. A cutting edge 47 formed between the front end of the rake surface 42 and the front end of the flank is inclined to the front end edge of the mounting surface 43.

可動刃４０がこのような形状を有することにより、ローター２０の回転に伴って、可動刃４０の切刃縁４７が固定刃３０の刃先縁に対して斜めに交わる形で近づくことができ、剪断能力が向上でき、剪断に伴う騒音をも低下させることができる。   The movable blade 40 having such a shape allows the cutting edge 47 of the movable blade 40 to approach the cutting edge of the fixed blade 30 obliquely as the rotor 20 rotates, thereby causing shearing. The capacity can be improved and the noise associated with shearing can also be reduced.

金属体の後面４６は取付面４３と直交する面とされており、切刃縁４７は金属体の一方の側面４０から他方の側面４０に行くに従って、後面４６の上端縁からの奥行き（Ｄ）及び取付面４３の前端縁からの高さ（Ｈ）が次第に短くなるように傾斜していることが望ましい。この形態においては、可動刃４０の切刃縁４７が固定刃３０の刃先縁に近づく際に、可動刃４０の逃げ面４１に相対する方向から見た場合に、可動刃４０の切刃縁４７が固定刃３０の刃先縁に対して斜めとなるだけで無く、すくい面４２に相対する方向から見た場合でも、可動刃４０の切刃縁４７が固定刃３０の刃先縁に対して斜めの関係で近づくことができ、より一層剪断能力が高められ、破砕時の騒音もより一層低下させることができる。   The rear surface 46 of the metal body is a surface orthogonal to the mounting surface 43, and the cutting edge 47 is a depth (D) from the upper end edge of the rear surface 46 as going from one side surface 40 to the other side surface 40 of the metal body. And it is desirable to incline so that height (H) from the front end edge of mounting surface 43 may become short gradually. In this embodiment, when the cutting edge 47 of the movable blade 40 approaches the cutting edge of the fixed blade 30, the cutting edge 47 of the movable blade 40 when viewed from the direction opposite to the flank 41 of the movable blade 40. Not only is oblique to the cutting edge of the fixed blade 30, but also when viewed from the direction opposite to the rake surface 42, the cutting edge 47 of the movable blade 40 is oblique to the cutting edge of the fixed blade 30. The relationship can be approached, the shearing ability can be further enhanced, and the noise upon crushing can be further reduced.

本発明に係る研磨治具は、上述の破砕機用刃物を研磨するための研磨装置にセットするための治具であり、この研磨装置は、治具を載置する平坦な研磨台１００と、この研磨台１００と平行な面内で移動する研磨ヘッド１１０とを備える。研磨治具は、上面、下面、正面、後面、両側面を有するブロック６０であり、ブロック６０の底面が研磨台１００に面接触する基底面６１を規定し、ブロック６０の上面に破砕機用刃物である可動刃４０を載置する載置面６２が形成される。ブロック６０の後面側には載置面６２より上方に突出するガイド６３が形成され、ガイド６３は可動刃４０の後面４６に面接触して可動刃４０をその前後方向で位置決めする第１位置決め面６４を備える。載置面６２は可動刃４０の取付面４３に合致する形状となり、基底面６１と所定の角度で傾斜してこの載置面６２に載置する可動刃４０のすくい面４２が上記基底面６１と平行な状態でブロック６０上面に露出する。ブロック６０には、載置面６２の一端で可動刃４０の一方の側面４４を受け止めて可動刃４０の左右方向の位置決めを行う第２位置決め面６５が形成される。   The polishing jig according to the present invention is a jig for setting in the above-mentioned polishing apparatus for polishing the cutter blade, and this polishing apparatus is a flat polishing table 100 on which the jig is placed; And a polishing head 110 moving in a plane parallel to the polishing table 100. The polishing jig is a block 60 having an upper surface, a lower surface, a front surface, a rear surface, and both side surfaces, and a bottom surface of the block 60 defines a base surface 61 in surface contact with the polishing table 100. A mounting surface 62 on which the movable blade 40 is mounted is formed. A guide 63 projecting upward from the mounting surface 62 is formed on the rear surface side of the block 60, and the guide 63 is in surface contact with the rear surface 46 of the movable blade 40 to position the movable blade 40 in the front-rear direction It has 64. The mounting surface 62 conforms to the mounting surface 43 of the movable blade 40, and the rake surface 42 of the movable blade 40 mounted on the mounting surface 62 is inclined at a predetermined angle with the base surface 61 and is the base surface 61. And exposed on the top surface of the block 60 in parallel with the The block 60 is formed with a second positioning surface 65 which receives the side surface 44 of the movable blade 40 at one end of the mounting surface 62 and positions the movable blade 40 in the left-right direction.

治具はその第１位置決め面６４と第２位置決め面６５で可動刃４０の２面を受け止めることで、可動刃４０のすくい面４２を研磨台１００と平行とした状態で、載置面６２上に可動刃４０を保持できる。このため、研磨台１００の平面と平行な面内で移動する研磨ヘッド１１０によって可動刃４０のすくい面４２を正しく研磨することができる。   The jig receives the two surfaces of the movable blade 40 by the first positioning surface 64 and the second positioning surface 65 to make the rake surface 42 of the movable blade 40 parallel to the polishing table 100. Can hold the movable blade 40. Therefore, the rake surface 42 of the movable blade 40 can be correctly polished by the polishing head 110 which moves in a plane parallel to the plane of the polishing table 100.

治具は複数の可動刃４０を一列に並べて保持することが望ましい。この場合、ブロック６０は長尺体となり、その長手方向に沿って複数の載置面６２が並んで形成され、隣り合う載置面６２同士が第２位置決め面６５で区画され、第２位置決め面６５が隣り合う載置面６２間の段差を形成する。このため、複数の可動刃４０が互いのすくい面４２を連続させる形で治具に保持することができ、複数の可動刃４０を同時に研磨することができる。   It is desirable that the jig hold the plurality of movable blades 40 in a row. In this case, the block 60 is an elongated body, and a plurality of mounting surfaces 62 are formed side by side along the longitudinal direction, and the adjacent mounting surfaces 62 are partitioned by the second positioning surface 65, and the second positioning surface 65 form a level | step difference between the mounting surfaces 62 which adjoin. Therefore, the plurality of movable blades 40 can be held by the jig in such a manner that the rake surfaces 42 of the plurality of movable blades 40 are continuous, and the plurality of movable blades 40 can be polished simultaneously.

可動刃４０は、その制作過程において、一方の側面４４から取付面４３に若干のバリが突出することがあるが、多少のバリがあっても、可動刃４０を正しい位置にセットできるようにすることが好ましい。この場合、載置面４２の左右方向の一端で第２位置決め面６５に近い箇所に、ガイド６３からブロック６０の正面に至る凹溝６７が形成され、この凹溝６７内にバリを収めることで、すくい面４２を研磨台と平行となるように正しくセットすることができる。   The movable blade 40 may have some burrs projecting from the side surface 44 to the mounting surface 43 in the manufacturing process, but even if there are some burrs, the movable blade 40 can be set in the correct position. Is preferred. In this case, a recessed groove 67 extending from the guide 63 to the front of the block 60 is formed at a position near the second positioning surface 65 at one end of the mounting surface 42 in the left-right direction. The rake face 42 can be set correctly to be parallel to the polishing table.

凹溝６７はブロック６０の正面に開口することが望ましい。これにより、バリのある可動刃４０であっても、可動刃４０を載置面６２の前方からスライドさせて載置面６２にセットすることができる。   It is desirable that the recessed groove 67 open in the front of the block 60. Thus, even with the movable blade 40 having burrs, the movable blade 40 can be slid from the front of the placement surface 62 and set on the placement surface 62.

以下、本発明の実施の形態を説明する。   Hereinafter, embodiments of the present invention will be described.

本発明の一実施形態に係る破砕機用刃物について、添付図面に基づいて、説明する。破砕機は、例えば、金属製品やプリント基板等の産業廃棄物である対象物Ｔを、所定の粒度の破砕片Ｆに破砕し、破砕片Ｆを取り出すように構成される。   A cutter for a crusher according to an embodiment of the present invention will be described based on the attached drawings. The crusher is configured to crush an object T, which is an industrial waste, such as a metal product or a printed circuit board, into shredded pieces F of a predetermined particle size and take out the shredded pieces F, for example.

図１に示すように、破砕機は、内部にローター２０を収容するハウジング１０と、ベルトコンベア２から搬送される対象物Ｔをハウジング１０内に落とし込む投入口１２と、ローター２０をその軸の回りで回転させるモーター１８を備える。ローター２０はその中心軸２１でハウジング１０へ支持され、この軸の回りに回転駆動され、周面に配置される複数の可動刃４０と、ハウジング１０側に配置された固定刃３０とで投入口１２から投入された対象物Ｔを切断する。ローター２０の下面側には、スクリーン３６が可動刃４０の回転軌跡Ｐに沿って配置される。このスクリーン３６は、図３に示すように、多数の排出孔３８を有し、湾曲したスクリーン３６に沿って移動する可動刃４０と排出孔３８の開口縁とで、対象物Ｔが破砕されるとともに、所定の粒度に破砕された破砕片Ｆを排出孔３８で篩い分けられる。篩い分けられた破砕片Ｆは、ハウジング１０下端のコレクタ１４に集められ、ダクト１６から外部へ送り出される。   As shown in FIG. 1, the crusher has a housing 10 for housing the rotor 20 therein, an inlet 12 for dropping the object T conveyed from the belt conveyor 2 into the housing 10, and the rotor 20 about its axis. The motor 18 is rotated at The rotor 20 is supported on the housing 10 by its central axis 21 and is rotationally driven around this axis, and a plurality of movable blades 40 disposed on the circumferential surface, and a fixed blade 30 disposed on the housing 10 side, and an insertion port The target T input from 12 is cut. The screen 36 is disposed along the rotation trajectory P of the movable blade 40 on the lower surface side of the rotor 20. As shown in FIG. 3, the screen 36 has a large number of discharge holes 38, and the object T is broken by the movable blade 40 moving along the curved screen 36 and the opening edge of the discharge hole 38. At the same time, the crushed pieces F crushed to a predetermined particle size are screened at the discharge holes 38. The sieved crushed pieces F are collected in the collector 14 at the lower end of the housing 10 and sent out from the duct 16 to the outside.

図２に示すように、ローター２０は複数の可動刃４０をその軸方向及び周方向に沿って並ぶ形で保持するように構成され、図３に示すように、外周面に配置した複数の台座２２にボルト２８を用いて固定する。台座２２はローター２０の軸方向に沿った平面である保持面２３と保持面２３に直角をなす背面２４を有し、保持面２３に設けたねじ穴２５にネジ止めされるボルト２８によって可動刃４０を台座２２に固定する。ローター２０は一方向に回転駆動され、ローター２０に装着された可動刃４０の先端が３００ｍｍ〜５００ｍｍの範囲内の直径の円軌跡Ｐを描く。   As shown in FIG. 2, the rotor 20 is configured to hold the plurality of movable blades 40 side by side along the axial direction and the circumferential direction, and as shown in FIG. 3, a plurality of pedestals arranged on the outer peripheral surface Fix it to 22 using a bolt 28. The pedestal 22 has a holding surface 23, which is a flat surface along the axial direction of the rotor 20, and a back surface 24 perpendicular to the holding surface 23, and the movable blade is screwed into a screw hole 25 provided in the holding surface 23. 40 is fixed to the pedestal 22. The rotor 20 is rotationally driven in one direction, and the tip of the movable blade 40 mounted on the rotor 20 draws a circular locus P having a diameter within the range of 300 mm to 500 mm.

可動刃４０は刃物鋼でできた六面体であり、図５〜図１０に示すように、底面が台座２２の保持面２３に一致する取付面４３となり、後面４６が台座２２の背面２４に合致するように、取付面４３と直交する面に仕上げられ、両側面４４も取付面４３を直交する面となる。この六面体の前面は固定刃３０に対向する逃げ面４１となり、上面がローター２０の回転方向前方に位置するすくい面４２を規定する。すくい面４２と逃げ面４１との間の刃先角は４０〜５０度であり、すくい面４２の前端縁と逃げ面４１の上端縁との間に切刃縁４７を形成する。図６及び図７に示すように、すくい面４２は後面４６及び取付面４３と非平行な面とされ、切刃縁４７は、一方の側面４４から他方の側面４４に行くに従って、後面４６の上端縁からの奥行き（Ｄ）及び取付面４３の前端縁からの高さ（Ｈ）が次第に短くなるように傾斜し、図６に示すように、切刃縁４７は後面４６に対して４度から７度の角度で傾斜し、図７に示すように、底面の取付面４３に対して５度から７度の角度で傾斜する。これらの角度は、可動刃４０が描く回転軌跡Pの直径に依存する。可動刃４０の後端部には上面から底面の取付面４３に貫通する取付孔４５が形成され、この取付孔４５を通すボルト２８が台座２２のねじ穴２５に螺着されて、可動刃４０がローター２０に保持される。   The movable blade 40 is a hexahedron made of blade steel, and as shown in FIGS. 5 to 10, the mounting surface 43 whose bottom surface matches the holding surface 23 of the pedestal 22 and whose back surface 46 matches the back surface 24 of the pedestal 22 As described above, the mounting surface 43 is finished to be a surface orthogonal to the mounting surface 43, and the both side surfaces 44 also become a surface orthogonal to the mounting surface 43. The front face of this hexahedron becomes a flank 41 facing the fixed blade 30, and the upper face defines a rake face 42 located forward of the rotor 20 in the rotational direction. The cutting edge angle between the rake surface 42 and the flank surface 41 is 40 to 50 degrees, and a cutting edge 47 is formed between the front end edge of the rake surface 42 and the top edge of the flank surface 41. As shown in FIGS. 6 and 7, the rake surface 42 is a surface that is not parallel to the rear surface 46 and the mounting surface 43, and the cutting edge 47 extends from one side 44 to the other side 44. Inclined so that the depth (D) from the upper end edge and the height (H) from the front end edge of the mounting surface 43 become shorter, and the cutting edge 47 is 4 degrees with respect to the rear surface 46, as shown in FIG. And incline at an angle of 5 to 7 degrees with respect to the bottom attachment surface 43, as shown in FIG. These angles depend on the diameter of the rotation path P drawn by the movable blade 40. A mounting hole 45 is formed in the rear end portion of the movable blade 40 so as to penetrate from the upper surface to the mounting surface 43 on the bottom, and a bolt 28 passing through the mounting hole 45 is screwed into the screw hole 25 of the pedestal 22. Is held by the rotor 20.

可動刃４０がローター２０の台座２２にセットされて、ローター２０と共に軸の回りで一方向に回転すると、図１に示すように、可動刃４０の切刃縁４７が円軌跡を描き、可動刃４０の切刃縁４７が固定刃３０の刃先縁に近づく際、図１１（Ａ）（Ｂ）（Ｃ）に示すように、可動刃４０の逃げ面４１に相対する方向から見た場合に、すなわち、回転軌跡Ｐに接する面内では、可動刃４０の切刃縁４７が固定刃３０の刃先縁に対して斜めの状態で進む間に、切刃縁４７がその全長に亘って固定刃３０の刃先縁と協働することで、切断性能を向上させる。また、図１２（Ａ）（Ｂ）（Ｃ）に示すように、すくい面４２に相対する方向から見た場合でも、すなわち、回転軌跡Ｐの中心を含む面内で見たときに、固定刃３０の刃先縁に対して、可動刃２０の切刃縁４７が斜めになった状態で進む間に、切刃縁４７がその全長に亘って固定刃３０の刃先縁に接することができ、より一層剪断能力が高められ、破砕時の騒音もより一層低下させる。   When the movable blade 40 is set on the base 22 of the rotor 20 and rotates in one direction around the axis together with the rotor 20, as shown in FIG. 1, the cutting edge 47 of the movable blade 40 draws a circular locus and the movable blade When viewed from the direction opposite to the flank surface 41 of the movable blade 40, as shown in FIGS. 11 (A), (B) and (C), when the cutting edge 47 of 40 approaches the cutting edge of the fixed blade 30. That is, while the cutting edge 47 of the movable blade 40 travels in an oblique state with respect to the cutting edge of the fixed blade 30 in the plane in contact with the rotation trajectory P, the cutting edge 47 covers the entire length thereof. The cutting performance is improved by cooperating with the cutting edge of the blade. Further, as shown in FIGS. 12A, 12B, and 12C, even when viewed from the direction opposite to the rake face 42, that is, when viewed in a plane including the center of the rotation trajectory P, the fixed blade The cutting edge 47 can be in contact with the cutting edge of the fixed blade 30 over its entire length while advancing while the cutting edge 47 of the movable blade 20 is inclined with respect to the cutting edge of 30. The shearing ability is further enhanced, and the noise upon crushing is further reduced.

可動刃４０は長時間使用により摩耗するため、公知の研磨装置を利用して定期的にすくい面４１を研磨することが求められる。この研磨装置は、図１８に示すように、研磨対象体を載置する研磨台１００と、研磨台１００に対して上下前後に移動する移動する研磨ヘッド１１０を備えており、研磨ヘッド１１０は水平軸の周りで回転駆動される回転砥石であり、研磨台１００が往復移動することで、研磨台１００上に固定する可動刃４０のすくい面４１を研磨する。   Since the movable blade 40 wears over a long period of time, it is required to periodically polish the rake surface 41 using a known polishing apparatus. This polishing apparatus, as shown in FIG. 18, includes a polishing table 100 on which an object to be polished is placed, and a polishing head 110 which moves up and down with respect to the polishing table 100, and the polishing head 110 is horizontal. It is a rotary grindstone driven to rotate around an axis, and as the polishing table 100 reciprocates, the rake surface 41 of the movable blade 40 fixed on the polishing table 100 is polished.

本発明において用いる可動刃４０は、すくい面４１が取付面４３である底面と非平行であることから、すくい面４１を上にして研磨台１００に乗せると、すくい面４１が傾斜面となるため、すくい面４１全体を研磨ヘッド１１０に対して亘って移動させて正確な研磨を行うことが困難となる。本発明に係る研磨用治具は、この不都合を解消するために準備された金属製のブロック６０である。このブロック６０は、複数の可動刃４０を一列に並べた状態で保持する構成をなし、図１８に示すように、研磨台１００に配備された電磁石１０２による磁気力で研磨台１００に固定される。 Movable blade 40 Ru used Oite the present invention, since the rake face 41 is a bottom nonparallel a mounting surface 43, when placed on the polishing table 100 and the rake face 41 to the top rake face 41 inclined surface As a result, it becomes difficult to move the entire rake surface 41 relative to the polishing head 110 to perform accurate polishing. The polishing jig according to the present invention is a metal block 60 prepared to eliminate this disadvantage. The block 60 is configured to hold a plurality of movable blades 40 in a line, and is fixed to the polishing table 100 by the magnetic force of the electromagnet 102 disposed on the polishing table 100, as shown in FIG. .

このブロック６０は、図１３〜図１５に示すように、上面、下面、正面、後面、両側面を有し、ブロック６０の底面が研磨台１００に面接触する基底面６１を規定し、上面に可動刃４０を載置する複数の載置面６２が形成される。ブロック６０の後面側には載置面６２より上方に突出するガイド６３が形成され、このガイド６３が可動刃４０の後面に面接触して可動刃４０をその前後方向で位置決めする第１位置決め面６４を形成している。載置面４２は可動刃４０の取付面４３に合致する形状となり、基底面６１と所定の角度で傾斜してこの載置面６２に載置する可動刃４０のすくい面４２が基底面６１と平行な状態でブロック６０の上面に露出する。ブロック６０には、更に、載置面４２の一端で可動刃４０の一方の側面４４を受け止めて可動刃４０の左右方向の位置決めを行う第２位置決め面６５が形成され、この第２位置決め面６５は、隣り合う載置面６２を区画する段差を形成する。   This block 60 has an upper surface, a lower surface, a front surface, a rear surface, and both side surfaces as shown in FIGS. 13 to 15, and the bottom surface of the block 60 defines a base surface 61 in surface contact with the polishing table 100. A plurality of mounting surfaces 62 on which the movable blade 40 is mounted are formed. A guide 63 protruding upward from the mounting surface 62 is formed on the rear surface side of the block 60, and the guide 63 is in surface contact with the rear surface of the movable blade 40 to position the movable blade 40 in the front-rear direction 64 forms. The mounting surface 42 has a shape that matches the mounting surface 43 of the movable blade 40, and the rake surface 42 of the movable blade 40 mounted on the mounting surface 62 is inclined at a predetermined angle with the base surface 61 Exposed on top of block 60 in a parallel fashion. The block 60 is further provided with a second positioning surface 65 for receiving the side surface 44 of the movable blade 40 at one end of the placement surface 42 to position the movable blade 40 in the left-right direction. Forms a step that divides the adjacent mounting surface 62.

各載置面６２の左右方向の一端で第２位置決め面６５に近い箇所には、ガイド６３からブロック６０の正面に至る凹溝６７が形成され、凹溝６７がブロック６０の正面に開口している。   A recessed groove 67 extending from the guide 63 to the front of the block 60 is formed at one end in the left-right direction of each mounting surface 62 and close to the second positioning surface 65, and the recessed groove 67 opens in the front of the block 60 There is.

図１６及び図１７に示すように、可動刃４０をその取付面４３を載置面６２に向けて治具にセットし、この状態で、各可動刃４０の取付孔４５から載置面６２のねじ穴６６へボルト２８を通して、可動刃４０を治具に固定する。これにより、可動刃４０のすくい面４２がブロック６０の基底面６１、すなわち、研磨台１００の表面と平行とされ、各可動刃４０のすくい面４２が一平面内で一列に並ぶ。図１６に示すように、研磨ヘッド１１０をすくい面４２まで下降させ、この状態で、研磨台１００を左右に移動させることで、各可動刃４０のすくい面４２を一様に研磨することができる。   As shown in FIGS. 16 and 17, the movable blade 40 is set in a jig with its mounting surface 43 facing the mounting surface 62, and in this state, the mounting surface 62 of the movable blade 40 is The movable blade 40 is fixed to a jig by passing the bolt 28 into the screw hole 66. As a result, the rake surface 42 of the movable blade 40 is parallel to the base surface 61 of the block 60, that is, the surface of the polishing table 100, and the rake surfaces 42 of the movable blades 40 are aligned in a line. As shown in FIG. 16, by lowering the polishing head 110 to the rake surface 42 and moving the polishing table 100 to the left and right in this state, the rake surface 42 of each movable blade 40 can be uniformly polished. .

可動刃４０は、その制作過程において、一方の側面４４から取付面４３に若干のバリが突出する場合があるが、そのようなバリは第２位置決め面６５の一端に形成した凹溝６７に収めることができ、すくい面４２を研磨台１００の表面と平行に保つことができる。この場合、凹溝６７はブロック６０の正面に開口していることから、バリのある可動刃４０であっても、可動刃４０を載置面６２の前方からスライドさせて載置面６２にセットすることができる。   In the production process of the movable blade 40, some burrs may protrude from the side surface 44 to the mounting surface 43, but such burrs are accommodated in the concave groove 67 formed at one end of the second positioning surface 65. And the rake face 42 may be kept parallel to the surface of the polishing table 100. In this case, since the concave groove 67 is opened in the front of the block 60, the movable blade 40 is slid from the front of the mounting surface 62 and set on the mounting surface 62 even for the movable blade 40 with burrs. can do.
