Description

本発明は、板材の平行な２辺を加工し、次に残る２辺を加工する加工方法及び同装置に関する。   The present invention relates to a processing method and apparatus for processing two parallel sides of a plate material and then processing the remaining two sides.

ヒートシンクと称するアルミニウム（以下、アルミと記す。）製放熱ブロックに、パワートランジスタなどを実装する電装品メーカを例に、発明の背景を説明する。
一般に、小規模の電装品メーカは、アルミの圧延機や大判のアルミ板から所望の縦横寸法の板材を切出す切出し装置や、切出した板を加工する加工装置を、所有していない。このような電装品メーカでは、所望の縦横寸法に精密に加工した、加工済みのアルミ板を仕入れて、この加工済みのアルミ板にパワートランジスタなどを実装する。 The background of the invention will be described by taking as an example an electrical component manufacturer that mounts a power transistor or the like on a heat dissipation block made of aluminum (hereinafter referred to as aluminum) called a heat sink.
In general, a small electrical component manufacturer does not have an aluminum rolling mill or a cutting device that cuts a plate material having desired vertical and horizontal dimensions from a large-sized aluminum plate or a processing device that processes the cut plate. Such an electrical component manufacturer purchases a processed aluminum plate that has been precisely processed to a desired vertical and horizontal dimension, and mounts a power transistor or the like on the processed aluminum plate.

すなわち、我が国では、分業化が進んでおり、溶解炉や圧延機を所有する材料供給者と、この材料供給者から大判のアルミ板（圧延されたアルミ板）を仕入れて、所望の縦横寸法に加工する加工者と、上記の電装品メーカとの三者が存在する。
加工者が所有する加工装置としては、フライスが２個備わっている双頭フライス盤が知られている（例えば、特許文献１参照。）。
特開２０００−７４１公報（図８、図１１、図１２） In other words, in Japan, the division of labor is progressing, and a large-sized aluminum plate (rolled aluminum plate) is purchased from the material supplier who owns the melting furnace and rolling mill, and the desired vertical and horizontal dimensions are obtained. There are three parties: the processor to process and the electrical component manufacturer.
As a processing apparatus owned by a processor, a double-headed milling machine having two milling machines is known (see, for example, Patent Document 1).
JP 2000-741 A (FIGS. 8, 11, and 12)

特許文献１を次図に基づいて説明する。
図５は従来の技術の基本原理を説明する図であり、（ａ）に示すように、ワーク載せ台１０１に、粗加工板１０２を載せ、この粗加工板１０２を主クランパー１０３で抑え、補助クランパー１０４、１０４で補助的に抑える。次に、一対のフライス１０５、１０５を回し、粗加工板１０２を進ませて、粗加工板１０２の平行な２辺１０６、１０６を仕上げる。仕上げた板は第１次加工板と呼ぶ。 Patent document 1 is demonstrated based on the following figure.
FIG. 5 is a diagram for explaining the basic principle of the prior art. As shown in FIG. 5A, a rough processed plate 102 is placed on a work platform 101, and this rough processed plate 102 is held by a main clamper 103 to assist. The clampers 104 and 104 are used to suppress the auxiliary. Next, the pair of milling cutters 105 and 105 are rotated to advance the roughing plate 102 to finish the two parallel sides 106 and 106 of the roughing plate 102. The finished plate is called the primary processed plate.

次に、（ｂ）に示すように、主クランパー１０３及び補助クランパー１０４、１０４を離し、主クランパー１０３を縦に貫通しているピストンロッド１０７で第１次加工板１０８を抑え、この状態で、ワーク載せ台１０１を９０°旋回させる。
続いて、（ｃ）に示すように、主クランパー１０３で抑え、補助クランパー１０４、１０４で補助的に抑えながら、第１次加工板１０８の残りの平行な２辺１０９、１０９を一対のフライス１０５、１０５で仕上げる。
これで、４辺１０６、１０６、１０９、１０９が仕上げられた第２次加工板を得ることができる。 Next, as shown in (b), the main clamper 103 and the auxiliary clampers 104, 104 are separated, and the primary processed plate 108 is suppressed by the piston rod 107 that vertically penetrates the main clamper 103. The work platform 101 is turned 90 °.
Subsequently, as shown in (c), the remaining two sides 109 and 109 of the primary processed plate 108 are paired with a pair of milling 105 while being restrained by the main clamper 103 and supplementarily by the auxiliary clampers 104 and 104. , 105 to finish.
Thus, a secondary processed plate having finished four sides 106, 106, 109, 109 can be obtained.

なお、圧延板は、上下面の平坦性や粗さが保証されているため、上下面の仕上げ加工は省くことができる。これに対して、粗加工板１０２は回転鋸などで切断して切出されるため、４辺１０６、１０６、１０９、１０９の平坦性や粗さは許容できない。そこで、４辺１０６、１０６、１０９、１０９をフライス１０５、１０５で仕上げる。   In addition, since the flatness and roughness of the upper and lower surfaces are guaranteed, the finished processing of the upper and lower surfaces can be omitted. On the other hand, since the rough processed plate 102 is cut and cut by a rotary saw or the like, the flatness and roughness of the four sides 106, 106, 109, 109 cannot be allowed. Therefore, the four sides 106, 106, 109, 109 are finished with the milling cutters 105, 105.

ところで、圧延で上下面の平坦性や粗さを保証した、大判のアルミ板が材料供給者から加工者まで運搬される過程で、大判のアルミ板の上下面に、衝突、接触などによる、疵が付くことがある。この疵付きを回避するために、材料供給者は、近年、大判のアルミ板の上下面に樹脂製保護膜を被せるという対策を講じるようになってきた。この対策により、疵付きは解消できるが、新たな問題が発生することが判明した。この新たな問題を図面に基づいて以下に説明する。   By the way, in the process of transporting large-size aluminum plates that have been secured from flatness and roughness to the upper and lower surfaces by rolling from the material supplier to the processor, May be attached. In order to avoid this wrinkle, material suppliers have recently taken measures to cover resin protective films on the upper and lower surfaces of large-sized aluminum plates. Although this measure can eliminate the wrinkle, it has been found that a new problem occurs. This new problem will be described below with reference to the drawings.

図６は樹脂製保護膜を被せた粗加工板の加工説明図であり、旋回機能を備えるワーク載せ台１１１に、粗加工板１１２より一回り小型の治具ブロック１１３を載せ、この治具ブロック１１３に、樹脂製保護膜１１４、１１４、１１４、１１４が付いている２枚の粗加工板１１２、１１５を重ね、上位の粗加工板１１５に治具ブロック１１６を載せ、この治具ブロック１１６をピストンロッド１１７で下方へ押すことで、フライス加工に備えて２枚の粗加工板１１２、１１５を固定する。ピストンロッド１１７の押力は、例えば１．５トンである。   FIG. 6 is a diagram for explaining the processing of a roughing plate covered with a resin protective film. A jig block 113 that is slightly smaller than the roughing plate 112 is placed on a work platform 111 having a turning function. 113, two roughened plates 112, 115 having protective films 114, 114, 114, 114 made of resin are stacked, and a jig block 116 is placed on the upper roughened plate 115. By pushing downward with the piston rod 117, the two roughened plates 112 and 115 are fixed in preparation for milling. The pushing force of the piston rod 117 is, for example, 1.5 tons.

図７は図６の７−７矢視図であり、（ａ）に示すように、一対のフライス１１８、１１８で平行な２つの辺１１９、１１９を加工する。加工した物は第１次加工板になる。
次に、図６に示すワーク載せ台１１１を９０°回す。このときに、ピストンロッド１１６をフリーにすると、粗加工板１１２、１１５が不安定になるので、例えば０．５トンの押力で抑える。 FIG. 7 is a view taken in the direction of arrow 7-7 in FIG. 6, and as shown in FIG. 7A, two parallel sides 119, 119 are machined by a pair of milling cutters 118, 118. The processed product becomes the primary processed plate.
Next, the work platform 111 shown in FIG. At this time, if the piston rod 116 is made free, the roughened plates 112 and 115 become unstable, and are suppressed by a pressing force of 0.5 ton, for example.

この状態で、ワーク載せ台１１１（図６）を図反時計方向に９０°回したところ、（ｂ）に示すように、下位の第１次加工板１２１は９０°旋回したが、上位の第１次加工板１２２は８９°だけしか回らなかった。この状態で、残りの２辺１２３、１２３をフライス１１８、１１８で加工すると、上位の加工板１２２のコーナ（隅）角が８９°と９１°に仕上がる。これでは、上位の加工板１２２は製品価値が無くなる。   In this state, when the work platform 111 (FIG. 6) is turned 90 ° counterclockwise in the figure, the lower primary working plate 121 is turned 90 ° as shown in FIG. The primary processed plate 122 turned only 89 °. In this state, when the remaining two sides 123 and 123 are machined by the millers 118 and 118, the corner angles of the upper machining plate 122 are finished at 89 ° and 91 °. In this case, the upper processed plate 122 has no product value.

この原因は、樹脂製保護膜１１４が滑りやすく、樹脂製保護膜１１４と樹脂製保護膜１１４との間に顕著な滑りが発生したと考えられる。試みに樹脂製保護膜 を除去して、図６〜図７を実施したところ問題は起こらなかった。
樹脂製保護膜１１４は、加工者から電装品メーカへ運搬するときにも疵や汚れ対策として有効である。
したがって、樹脂製保護膜１１４が付いたままで４辺加工が可能であることが望まれる。 This is considered to be because the resin protective film 114 is slid easily and a significant slip occurs between the resin protective film 114 and the resin protective film 114. When the resin protective film was removed as an attempt and FIGS. 6 to 7 were carried out, no problem occurred.
The resin protective film 114 is also effective as a measure against wrinkles and dirt when transported from a processor to an electrical component manufacturer.
Therefore, it is desirable that four-side processing can be performed with the resin protective film 114 attached.

The drawings are viewed in the direction of the reference numerals.
FIG. 1 is a front view of a processing apparatus according to the present invention. The processing apparatus 10 includes a column 13 standing on a foundation 11 or a machine base 12, a workpiece platform 14 provided at the upper end of the column 13, and the workpiece mounting. In order to hold down the jig block 15, the rough processed plates 16 and 16 and the jig block 17 placed on the base 14 from above, the piston rod 19 provided on the base frame 18 standing from the base 11 or the machine base 12 is directed downward. A cylinder unit 21, ring rails 22, 23 provided on the foundation 11 or the machine base 12 around the work platform 14, and a turntable 24 that is horizontally swiveled on these ring rails 22, 23, The two parallel sides of the rough processed plates 16 and 16 are simultaneously processed on the turntable 24 to form a first processed plate, and the first processing is performed after the turntable is turned 90 °. A pair of milling machine 30, 30 Metropolitan to secondary processing plate by processing the remaining two sides parallel simultaneously. The turntable 24 is turned by a servo motor.

図左のフライス盤３０は、ターンテーブル２４に載っている箱状のテーブル３１と、このテーブル３１の上に敷いた下レール３２、３２と、これらの下レール３２、３２に支持されて図面表裏方向に移動する下部スライダ３３と、この下部スライダ３３の上に敷いた上レール３４と、この上レール３４に支持されて図面左右方向に移動する上部スライダ３５と、この上部スライダ３５に載っている主軸台３６と、この主軸台３６で回転自在に支持されている主軸３７を駆動する駆動モータ３８及びベルト３９と、主軸３７に取付けられたフライス４０とからなる。図右のフライス盤３０も同様の構成物であるため、符号を流用し、詳細な構造説明は省略する。   The milling machine 30 on the left side of the figure is a box-shaped table 31 mounted on a turntable 24, lower rails 32 and 32 laid on the table 31, and supported by these lower rails 32 and 32 in the front and back direction of the drawing. A lower slider 33 that moves on the lower slider 33, an upper rail 34 that is laid on the lower slider 33, an upper slider 35 that is supported by the upper rail 34 and moves in the horizontal direction of the drawing, and a spindle that is mounted on the upper slider 35 It comprises a table 36, a drive motor 38 and a belt 39 that drive a main shaft 37 that is rotatably supported by the main shaft table 36, and a milling cutter 40 attached to the main shaft 37. Since the milling machine 30 on the right side of the figure has the same structure, the reference numerals are used and the detailed description of the structure is omitted.

以上の構成からなる加工装置１０の作用を以下に説明する。
図２は加工装置の作用説明図であり、ワーク載せ台１４に治具ブロック１５を載せる。そして、上下面が樹脂製保護膜４１、４１で被われている粗加工板１６を２枚重ねて治具ブロック１５に載せる。その上に治具ブロック１７を載せる。この治具ブロック１７を、シリンダユニット２１のピストンロッド１９で押し下げる。押力は高く設定でき、例えば１．８トンとする。 The operation of the processing apparatus 10 having the above configuration will be described below.
FIG. 2 is a diagram for explaining the operation of the processing apparatus, and the jig block 15 is placed on the work platform 14. Then, two roughened plates 16 whose upper and lower surfaces are covered with resin protective films 41 and 41 are stacked and placed on the jig block 15. A jig block 17 is placed thereon. The jig block 17 is pushed down by the piston rod 19 of the cylinder unit 21. The pressing force can be set high, for example, 1.8 tons.

粗加工板１６は、アルミ板、ステンレス板、チタン板、高級炭素鋼などの金属板や、樹脂板、高級木板、セラミックス板、ガラス板などの非金属板が適用できる。アルミ板であれば、厚さが８ｍｍ〜１５０ｍｍで縦寸法が１５ｍｍ〜３００ｍｍで横寸法が２０ｍｍ〜３００ｍｍまで加工できる。
また、樹脂製保護膜４１は０．０８ｍｍ（８０μｍ）〜０．１５ｍｍ（１５０μｍ）の厚さの塩化ビニルが好適である。 The rough processed plate 16 may be a metal plate such as an aluminum plate, a stainless plate, a titanium plate, or a high-grade carbon steel, or a non-metal plate such as a resin plate, a high-grade wood plate, a ceramic plate, or a glass plate. If it is an aluminum plate, it can be processed to a thickness of 8 mm to 150 mm, a vertical dimension of 15 mm to 300 mm, and a horizontal dimension of 20 mm to 300 mm.
The resin protective film 41 is preferably vinyl chloride having a thickness of 0.08 mm (80 μm) to 0.15 mm (150 μm).

下レール３２、３２、３２、３２に沿って下部スライダ３３、３３を図面奥へ移動する。次に、上レール３４、３４に沿って上部スライダ３５、３５を図面左右へ移動させることでフライス４０とフライス４０との間隔を所定の幅（仕上げ幅）に調節する。
フライス４０、４０を回し、下部スライダ３３、３３を図面手前へ移動する。これで、粗加工板１６、１６の平行な２辺を加工することができる。 The lower sliders 33, 33 are moved along the lower rails 32, 32, 32, 32 to the back of the drawing. Next, the distance between the milling cutter 40 and the milling cutter 40 is adjusted to a predetermined width (finishing width) by moving the upper sliders 35, 35 along the upper rails 34, 34 to the left and right of the drawing.
The milling cutters 40 and 40 are turned to move the lower sliders 33 and 33 toward the front of the drawing. Thus, the two parallel sides of the rough processed plates 16 and 16 can be processed.

図３はフライスの作用説明図であり、（ａ）に示すように、粗加工板１６の平行な２辺４２、４２を加工し、加工が終わったらフライス４０、４０を元の位置に戻す。そして、フライス４０、４０を反時計方向に９０°旋回させる（矢印Ａ）。
この旋回により、（ｂ）に示すように、フライス４０、４０は、第１次加工板４３の図右側へ移動する。次に、このフライス４０、４０で第１次加工板４３の残りの平行な２辺４４、４４を加工する。
この間、粗加工板１６や第１次加工板４３は、固定したままである。フライス４０、４０はサーボモータにより正確に９０°旋回させることができる。したがって、得られる第２加工板はコーナ（隅）の角度が正確に９０°となり、高い精度の製品となる。 FIG. 3 is an explanatory view of the operation of the milling machine. As shown in FIG. 3A, the two parallel sides 42 and 42 of the roughened plate 16 are machined, and when the machining is finished, the milling machines 40 and 40 are returned to their original positions. Then, the milling cutters 40, 40 are turned 90 ° counterclockwise (arrow A).
By this turning, as shown in (b), the milling cutters 40, 40 move to the right side of the primary processed plate 43 in the figure. Next, the remaining two parallel sides 44 and 44 of the primary processing plate 43 are processed by the milling cutters 40 and 40.
During this time, the roughing plate 16 and the primary processing plate 43 remain fixed. The milling cutters 40, 40 can be turned exactly 90 ° by a servo motor. Therefore, the obtained second processed plate has a corner (corner) angle of exactly 90 °, and becomes a highly accurate product.

図４は本発明の加工方法を説明する図である。
（ａ）にて、上下面が樹脂製保護膜４１、４１で被われている、大判の板材４６を準備する（準備工程）。大判の板材４６から、所望の縦横寸法に加工代を加えた寸法で板を切出す（切出し工程）。
（ｂ）にて、得られた粗加工板１６を上下から抑えて固定し、粗加工板１６の４辺のうち、平行な２つの辺４２、４２を２個のフライスで同時に加工する（第１次加工工程）。 FIG. 4 is a diagram for explaining the processing method of the present invention.
In (a), a large-sized plate material 46 whose upper and lower surfaces are covered with resin protective films 41 and 41 is prepared (preparation step). A board is cut out from a large-sized plate material 46 in a dimension obtained by adding a machining allowance to a desired vertical and horizontal dimension (cutout process).
In (b), the obtained roughing plate 16 is held down and fixed, and two parallel sides 42 and 42 of the four sides of the roughing plate 16 are simultaneously processed by two milling cutters (first). Primary processing step).

（ｃ）にて、得られた第１次加工板４３は固定したままで、２個のフライスを移動させることで、残りの平行な２つの辺４４、４４を同時に加工する（第２次加工工程）。
これで（ｄ）に示すようにして、所望の縦横寸法の第２次加工板４７を得ることができる。すなわち、この第２次加工板４７も上下面が樹脂製保護膜４１、４１で被われている。 In (c), the remaining primary sides 44 and 44 are simultaneously processed by moving the two milling cutters while the obtained primary processed plate 43 is fixed (secondary processing). Process).
Thus, as shown in (d), the secondary processed plate 47 having desired vertical and horizontal dimensions can be obtained. That is, the upper and lower surfaces of the secondary processing plate 47 are covered with the resin protective films 41 and 41.

第２次加工板４７は、加工者から注文者（電装品メーカなど）まで運ばれるが、この運搬の過程で擦り疵や打ち疵が着くと、第２次加工板 の製品価値が著しく低下する。しかし、本発明によれば、第２次加工板４７は、上下面が樹脂製保護膜４１、４１で被われているため、上下面に擦り疵や打ち疵が着く心配はない。そのため、梱包も簡単化することができ、梱包費用を低減することができる。   The secondary processed plate 47 is transported from the processor to the orderer (electrical component manufacturer, etc.). If scuffs or hammers arrive during this transport process, the product value of the secondary processed plate significantly decreases. . However, according to the present invention, since the upper and lower surfaces of the secondary processing plate 47 are covered with the resin protective films 41 and 41, there is no fear that the upper and lower surfaces will be rubbed or hammered. Therefore, packing can be simplified and packing cost can be reduced.

図２で明示したように、本発明によれば、複数の粗加工板１６、１６を段積みして、一度に加工を施すとことができるため、加工能率が上がる。
また、図１に示した加工装置１０では、上下面が樹脂製保護膜４１、４１で被われている粗加工板１６の他、上下面が樹脂製保護膜４１、４１で被われていない、普通の粗加工板や上下面に防錆油を塗布した粗加工板、上下面に着色を施した粗加工板の何れも、加工可能である。 As clearly shown in FIG. 2, according to the present invention, a plurality of rough processed plates 16, 16 can be stacked and processed at a time, so that the processing efficiency is increased.
Further, in the processing apparatus 10 shown in FIG. 1, the upper and lower surfaces are not covered with the resin protective films 41 and 41 in addition to the rough processed plate 16 whose upper and lower surfaces are covered with the resin protective films 41 and 41. Either an ordinary roughened plate, a roughened plate coated with anti-rust oil on the upper and lower surfaces, or a roughened plate colored on the upper and lower surfaces can be processed.

したがって、粗加工板は樹脂製保護膜の有無は問わない。また、一度に加工する粗加工の枚数は、１枚、２枚（２段重ね）、３枚以上（３段重ね以上）の何れであっても良い。   Therefore, it does not matter whether the rough processed plate has a resin protective film. Further, the number of roughing processed at one time may be any one of 1, 2 (two-stage stack), and three or more (three-stage stack).

本発明は、上下面が約１２０μｍの塩化ビニルで被覆されているアルミ板の４辺加工に好適である。   The present invention is suitable for four-side processing of an aluminum plate whose upper and lower surfaces are coated with about 120 μm of vinyl chloride.
