本発明はプレス機械を用いて、積層板を打抜加工する場
合において、打抜力及び引抜力を測定する装置に関する
。DETAILED DESCRIPTION OF THE INVENTION r Industrial Application Field The present invention relates to an apparatus for measuring punching force and pulling force when punching a laminate using a press machine.
積層板加工の基本工程として、部品取付用の穴あけ加工
がある。この加工は、積層板の素材の材質にもよるが、
通常プレス機械に打抜用の金型一式を取付けて行う。The basic process of laminated board processing involves drilling holes for parts attachment. This processing depends on the material of the laminate, but
This is usually done by attaching a set of punching dies to a press machine.
打抜加工は生産性、積層板の割れ防止、打抜穴の仕上り
状態等の要因から、打抜時に打抜穴周辺を強固に押える
ことが効果的である。In the punching process, it is effective to firmly press the area around the punched hole during punching due to factors such as productivity, prevention of cracking of the laminate, and finish of the punched hole.
このため金型の構造に改良を加え、金型とは別に油圧装
置を取付け、これによシ打抜く寸前に積層板を押えると
いう技術を用いる。For this purpose, the structure of the die was improved and a hydraulic system was installed separately from the die, using a technology that presses the laminate just before punching.
一方、銅張積層板等のプリント回路基板にとって、打抜
特性は重要な特性のひとつであり、打抜きの前処理とし
ての加熱条件、打抜穴の仕上り等の全打抜加工工程を考
慮した積層板の改良検討が為され、新製品の開発が行わ
れている。On the other hand, punching characteristics are one of the important characteristics for printed circuit boards such as copper-clad laminates, and the lamination process takes into consideration the entire punching process, such as heating conditions as a pretreatment for punching and finishing of punched holes. Improvements to the board are being considered and new products are being developed.
打抜加工特性の重要要素として、 （１）打抜力、 （２）引抜力 がある。As an important element of punching processing characteristics, (1) Punching force, (2) Pulling force There is.
打抜力とは、金型にて積層板を打抜く時の抵抗力であシ
、打抜速度尋機械側の条件によっても変化するし、積層
板の種類、加熱条件等によっても変化する。Punching force is the resistance force when punching a laminate with a die, and it varies depending on the punching speed, machine conditions, type of laminate, heating conditions, etc.
引抜力とは、金型にて積層板を打抜いた後、打抜ビンを
積層板から引抜く時の抵抗力である。The pulling force is the resistance force when the punched bottle is pulled out from the laminate after the laminate is punched out with a die.
打抜力及び引抜力の測定は、従来ピン数の非常に少ない
金型を使用して実施されていた。この場合、通常金型の
取付部にロードセルを取付け、これにより加圧力、引張
力を測定する方式が採用されていた。この方式によると
、ロードセル自体も打抜時高速で運動するためデータが
ばらつく、打抜金型交換毎にロードセルをセットし直す
必要がある、ピン数を多くすることができない、定格以
上の応力が加わると使用不能となる等、再現性、実用性
の面において問題があった。Measurements of punching force and pulling force have conventionally been carried out using a mold with a very small number of pins. In this case, a method has been adopted in which a load cell is usually attached to the attachment part of the mold and the pressure and tensile force are measured using this. According to this method, the data varies because the load cell itself moves at high speed during punching. It is necessary to reset the load cell every time the punching die is replaced. The number of pins cannot be increased. There were problems in terms of reproducibility and practicality, such as making it unusable if added.
ま友、打抜力、引抜力はプレスの１ストローク中に両方
発生するものであり、両動作とも非常に早い現象である
ので、これを記録紙等に残すことは非常に困難であった
。The punching force and the pulling force are both generated during one stroke of the press, and since both operations are extremely rapid phenomena, it has been extremely difficult to record them on recording paper or the like.

置に記憶させ、打抜力の測定について説明する。The frame is stretched under tension, and the temporal changes in frame deformation during laminate punching are converted into electrical signals via a strain gauge.
On the other hand, a device that presses the laminate using hydraulic pressure during punching is activated when pulling out the laminate after punching, converts the temporal change in the hydraulic pressure during pulling into an electrical signal, and records both electrical signals. The following describes how to store the punching force in the device and measure the punching force.

ジ（５）を固定する。In order to find the correlation between the deformation of the frame of the punching press and the punching force during punching, as shown in Fig. 1, there is a A hydraulic jack (4) is set in place of the punching die, and a strain gauge (5) is attached to an appropriate position on the frame (1) of the punching press to measure the deformation of the frame. In this state, operate the punching press and use the hydraulic jack (

るものである。To measure the pulling force, a device that presses the area around the punched hole during punching is used, as shown in FIG. This device is commonly used by being attached to a press during punching. Just before the punching process, the holder plate (6) presses down the laminate using hydraulic pressure, and after the punching process is complete, the hydraulic pressure is released. When the laminate plate (9) is pulled out from the punching pin (7), the holder plate (6) pushes the laminate plate (9) again by the hydraulic pressure (8). As shown in Fig. 4, the temporal change in the oil pressure (8) at the time of pulling out is converted into an electric signal (voltage) by a hydraulic-electrical converter (11), stored in a recording device (12), and recorded on recording paper, etc. shall be recorded.

A recording device is used that sequentially takes out the information and records it on recording paper or the like.
