Description
本発明は、プレス部品等の側面に穴を明けるための側面穴明け装置に関する。 The present invention relates to a side surface drilling device for making a hole in a side surface of a pressed part or the like.
例えば、図８に示すような、厚さ0.3mm程度のＳＵＳよりなるプレス部品の側面に穴を明ける場合、穴明けパンチとプレス部品の内部に挿入される穴明けダイとによりプレス部品の側面に穴を明けているが、従来の側面穴明け装置では、金型の上型に穴明けダイとカムを組み込み、下型に穴明けパンチが固定されたスライドカムを組み込んでいる。 For example, when making a hole in the side surface of a pressed part made of SUS having a thickness of about 0.3 mm as shown in FIG. 8, the side surface of the pressed part is formed by a punching punch and a punching die inserted inside the pressed part. In the conventional side surface drilling apparatus, a drilling die and a cam are incorporated in the upper mold of the mold, and a slide cam in which a drilling punch is fixed is installed in the lower mold.
図９は従来の側面穴明け装置を示す図であり、下型ダイ１にプレス部品２を固定する固定台３と、穴明けパンチ４が固定されたスライドカム５とが設けられている。このスライドカム５は下型ダイ１に設けられたスライドスリット（図示せず）内で摺動可能となっているとともに、スプリング（図示せず）により図面右方向に付勢されている。
一方、上型６はパンチプレート７、スペーサ８、ストリッパ９よりなり、これらは穴明け時に駆動機構（図示せず）により自動的に下降させられる。そして、パンチプレート７にスライドカム５を駆動するカム１０が固定されるとともに、先端に穴明けダイ１１が形成されたダイ支持具１２がスペーサ８に取り付けられている。なお、穴明けダイ１１の側面には穴明けパンチ４の先端が侵入可能な横穴が形成されている。
FIG. 9 is a view showing a conventional side surface drilling device, in which a fixing base 3 for fixing a press part 2 to a lower die 1 and a slide cam 5 to which a punching punch 4 is fixed are provided. The slide cam 5 is slidable in a slide slit (not shown) provided in the lower die 1 and is urged rightward in the drawing by a spring (not shown).
On the other hand, the upper die 6 includes a punch plate 7, a spacer 8, and a stripper 9, which are automatically lowered by a driving mechanism (not shown) when drilling. A cam 10 for driving the slide cam 5 is fixed to the punch plate 7, and a die support 12 having a perforated die 11 formed at the tip is attached to the spacer 8. In addition, a lateral hole into which the tip of the punching punch 4 can enter is formed on the side surface of the punching die 11.
従来の側面穴明け装置は上記のように構成されており、プレス部品２に側面穴を明ける場合、固定台３にプレス部品２がセットされた後、図１０に示すように上型６が下降し、穴明けダイ１１がプレス部品２の内部に侵入した後、パンチプレート７が更に下降するので、カム１０によりスライドカム５が押されて図示矢印方向に摺動し、穴明けパンチ４と穴明けダイ１１によりプレス部品２の側面への穴明けが行われる。 The conventional side hole drilling device is configured as described above. When a side hole is drilled in the press part 2, the upper part 6 is lowered as shown in FIG. Then, after the punching die 11 has entered the inside of the press part 2, the punch plate 7 is further lowered, so that the slide cam 5 is pushed by the cam 10 and slides in the direction of the arrow shown in the figure. A hole is formed in the side surface of the pressed part 2 by the opening die 11.
従来の側面穴明け装置は上記のように構成されているが、穴明けパンチ、スライドカムが下型に組み込まれ、穴明けダイとカムが上型に組み込まれているため、プレスの有するストローク精度では穴明けパンチと穴明けダイの位置関係が安定せず、図１１（ａ）に示すように、穴明けパンチと穴明けダイの横穴位置とが多少ずれる場合がある。
穴明けパンチと穴明けダイの位置関係がずれた場合、図１１（ｂ）に示すように、穴明けパンチ４と穴明けダイの横穴１５とのクリアランスが不均一となり、製品精度が悪くなって、穴バリが発生する原因となっていた。
The conventional side hole drilling device is constructed as described above, but the punching punch and slide cam are built into the lower mold, and the drilling die and cam are built into the upper mold, so the stroke accuracy of the press Then, the positional relationship between the drilling punch and the drilling die is not stable, and as shown in FIG. 11A, the position of the punching punch and the horizontal hole of the drilling die may be slightly shifted.
When the positional relationship between the drilling punch and the drilling die is deviated, the clearance between the punching punch 4 and the horizontal hole 15 of the drilling die is not uniform as shown in FIG. This was the cause of hole burrs.
本発明は、上記の問題に鑑みてなされたもので、穴明けパンチと穴明けダイのクリアランスを均一とし、精度の高い穴明けを行うことができる側面穴明け装置を提供することを目的とする。 The present invention has been made in view of the above problems, and an object of the present invention is to provide a side surface drilling device that can make the drilling punch and the punching die have a uniform clearance and can perform highly accurate drilling. .

以下、本発明の側面穴明け装置の実施例について、図面を用いて説明する。図１は本発明の側面穴明け装置の側面図であり、下型ダイ１にプレス部品２を固定する固定台３が設けられ、上型６はパンチプレート７、スペーサ８、ストリッパ９よりなり、これらは従来と同様に、穴明け時に駆動機構（図示せず）により自動的に下降させられる。そして、パンチプレート７にスライドカム５を駆動するカム１０が固定されるとともに、先端に穴明けダイ１１が形成されたダイ支持具１２がスペーサ８に取り付けられている。 Hereinafter, embodiments of the side hole drilling device of the present invention will be described with reference to the drawings. FIG. 1 is a side view of a side surface drilling apparatus according to the present invention. These are automatically lowered by a drive mechanism (not shown) at the time of drilling, as in the prior art. A cam 10 for driving the slide cam 5 is fixed to the punch plate 7, and a die support 12 having a perforated die 11 formed at the tip is attached to the spacer 8.
また、穴明けパンチ４が固定されたスライドカム５は、図２に示すようにスライドカムホルダー１３内に摺動可能に配置され、スプリング（図示せず）により図１の右方向に付勢されている。スライドカムホルダー１３はスライドカム５を囲うようなコの字形状をしており、このスライドカムホルダー１３がボルト１４によりスペーサ８に固定されている。また、図２に示すように、下型ダイ１のスライドカムホルダー１３に対応する部分はスライドカムホルダー１３が当たらないようざぐられている。 The slide cam 5 to which the punch 4 is fixed is slidably disposed in the slide cam holder 13 as shown in FIG. 2, and is urged to the right in FIG. 1 by a spring (not shown). ing. The slide cam holder 13 has a U-shape that surrounds the slide cam 5, and the slide cam holder 13 is fixed to the spacer 8 by a bolt 14. Further, as shown in FIG. 2, the portion corresponding to the slide cam holder 13 of the lower die 1 is swept so that the slide cam holder 13 does not hit.
このスライドカム５のプレート８への取付方法について、図３〜図５により簡単に説明する。なお、図３（ａ）、（ｂ）、図４（ａ）、図５（ａ）は側面図であり、図３（ｃ）、図４（ｂ）、図５（ｂ）は正面図である。
穴明けパンチ４が固定されたスライドカム５を、図３に示すように、コの字型のスライドカムホルダー１３内に入れることにより、図４に示すように、スライドカム５はコの字型のスライドカムホルダー１３の中を摺動可能となる。次に、図５に示すように、コの字型のスライドカムホルダー１３をスペーサ８にボルト１４で固定し、スプリング（図示せず）で図５（ａ）の右方向に付勢することにより、スライドカム５を上型６に摺動可能に組み込むことができる。
A method for attaching the slide cam 5 to the plate 8 will be briefly described with reference to FIGS. 3 (a), (b), FIG. 4 (a), and FIG. 5 (a) are side views, and FIG. 3 (c), FIG. 4 (b), and FIG. 5 (b) are front views. is there.
The slide cam 5 to which the punch 4 is fixed is placed in a U-shaped slide cam holder 13 as shown in FIG. 3, so that the slide cam 5 is U-shaped as shown in FIG. The slide cam holder 13 can be slid. Next, as shown in FIG. 5, the U-shaped slide cam holder 13 is fixed to the spacer 8 with bolts 14 and is urged to the right in FIG. 5A by a spring (not shown). The slide cam 5 can be slidably incorporated in the upper mold 6.
次に、図１の側面穴明け装置を使用してプレス部品２に側面穴を明ける場合の作用について説明する。
固定台３にプレス部品２がセットされた後、上型６が下降し、穴明けダイ１１がプレス部品２の内部に侵入した後、パンチプレート７が更に下降するので、図６に示すように、カム１０によりスライドカム５が押されてスライドカムホルダー１３の中を図示矢印方向に摺動し、穴明けパンチ４と穴明けダイ１１によりプレス部品２の側面への穴明けが行われる。
Next, an operation in the case of making a side hole in the pressed part 2 using the side hole drilling apparatus of FIG. 1 will be described.
After the press part 2 is set on the fixed base 3, the upper die 6 is lowered, and after the punching die 11 enters the inside of the press part 2, the punch plate 7 is further lowered, as shown in FIG. Then, the slide cam 5 is pushed by the cam 10 and slides in the slide cam holder 13 in the direction of the arrow shown in the figure, and the punching punch 4 and the punching die 11 punch the side surface of the press part 2.
穴明け後、パンチプレート７が上昇すると、カム１０の上昇につれてスプリングによりスライドカム５が右方向に摺動し、穴明けパンチ４がプレス部品２から離れる。この後、スペーサ８、ストリッパ９が上昇し、穴明けダイ１１が上昇してプレス部品２から離れるので、把持機構（図示せず）により側面穴が明けられたプレス部品２を次工程に搬送することができる。
そして、側面穴が明けられたプレス部品２の搬送後、新たなプレス部品を固定台３にセットすることにより、連続的にプレス部品の穴明けを実行することができる。
When the punch plate 7 is lifted after drilling, the slide cam 5 is slid rightward by the spring as the cam 10 is lifted, and the punch 4 is separated from the press part 2. Thereafter, the spacer 8 and the stripper 9 are lifted, and the punching die 11 is lifted and separated from the press part 2, so that the press part 2 whose side holes are drilled by a gripping mechanism (not shown) is conveyed to the next process. be able to.
Then, after conveying the press part 2 with the side holes drilled, by setting a new press part on the fixed base 3, the punching of the press part can be executed continuously.
以上のように、穴明けダイ１１と穴明けパンチ４が固定されたスライドカム５が金型の上型に組みこまれており、プレスの有するストロークが不安定であっても、図７（ａ）に示すように穴明けパンチと穴明けダイの横穴との位置関係が一定であるので、図７（ｂ）に示すように、穴明けパンチ４とダイ１１の横穴１５とのクリアランスを均一とし、精度の高い穴明けを行うことができ、穴バリの発生を防止することが可能となる。 As described above, even if the slide cam 5 to which the punching die 11 and the punching punch 4 are fixed is incorporated in the upper die of the mold, and the stroke of the press is unstable, FIG. As shown in FIG. 7 (b), the clearance between the punching punch 4 and the horizontal hole 15 of the die 11 is made uniform. Therefore, it is possible to perform drilling with high accuracy and to prevent occurrence of hole burrs.
