品が素材の打抜き孔に押し戻されて製品輪郭に著しい損
傷を与えるという欠点があった。Conventionally, precision punching requires a three-motion press with punching force, plate pressing force, and reverse pressing force, so a dedicated precision punching press is used, but as a method to reduce capital investment,
Single-acting general-purpose presses are being used for precision punching. When using a single-acting press, hydraulic pressure, pneumatic pressure, and the elastic force of springs, rubber, etc. are used as the power source for the plate press force and reverse press force. It is the cheapest and has the simplest structure. However, methods that utilize the elastic force of springs, rubber, etc. cannot adjust the product ejection timing, so the punched product is pushed back into the punched hole in the material, causing significant damage to the product contour.

The plate pressing force is transmitted to the plate material 8, and the annular protrusion 9a of the plate holder 9 presses the plate material 8.
The presser foot near the punching surface becomes stronger. When the upper ram 1 further descends, the punching force is transmitted to the punching punch 6 via the upper die table 2 and the upper adapter 5 to punch out the product 32 from the board 8. As the punched bond 6 descends, the ejector 29 and spacer 30 descend against the elastic force of the urethane rubber 31.

打抜き孔８ａに押込まれるのを防ぐことができる。When the spacer 30 descends, a stopper 3 is inserted into the gap created between the spacer 30 and the plate portion 24 of the lower adapter 25.
6 is pushed in by the biasing force of the spring 35. This stopper 36 prevents the ejector 29 from returning unnecessarily. After the punching process is completed, the upper ram 1 rises and the punching punch 6 rises, and as the upper ram 1 further rises, the plate holder 9 has a time lag corresponding to the play in the bolt 13 attachment part. and rise. When the plate holder 9 is raised, the plate 8 is held by a material holder (not shown) that is previously attached to the plate holder 10 and lifted upward. When the upper ram 1 further rises, the slope 7a of the stopper drawer 7 attached to the plate portion 4 of the upper adapter 5 pushes the slope 36a of the stopper 36 to the deenergized side of the spring 35, and the stopper 36 is moved between the spacer 30 and the lower adapter 25. Pull it out from between the plate part 24. As the stopper 36 is pulled out, the spacer 30 and ejector 29 are raised by the elastic force of the urethane rubber 31, and the product 32 is ejected from the die 27. This method can prevent the product 27 from being pushed into the punched hole 8a of the plate material 8.
