The daily use and maintenance of the rotary punch is very important!

 　　 Rotary punch is installed on the stamping die to perform continuous punching and punching operations to separate or plastically deform the processed material to obtain the required finished or semi-finished products. If it is not maintained, no matter how good the punch is, it will not last long. Therefore, daily use and maintenance are very important!

　　 Preparation before use:

　　 1. Thoroughly clean the upper mold sleeve before use.

　　2. Check whether there are scratches or dents on the surface. If yes, remove with oilstone.

　　 3. Oiling inside and out.

　　 Matters needing attention when installing the punch on the upper die sleeve

　　 1. Clean the punch and oil its long handle.

　　2. Insert the punch into the bottom of the upper mold sleeve on the large-station mold, and do not use force. Nylon hammers cannot be used. During installation, the punch cannot be fixed by tightening the bolt on the upper die sleeve, and the bolt can be tightened only after the punch is correctly positioned.

　　 If you want to extend the service life of the mold, the gap between the outer diameter of the upper mold sleeve and the turret hole should be as small as possible. So please perform the following procedures carefully.

　　1. Clean the keyway and inner diameter of the turret hole and apply oil.

　　2. Adjust the keyway of the upper die guide sleeve to match the key of the turret hole.

　　3. Insert the upper mold sleeve straight into the tower hole, being careful not to have any tilt. The upper die guide sleeve should slide into the turret hole by its own weight.

　　 4. If the upper mold sleeve is inclined to one side, use a soft material tool such as a nylon hammer to tap it lightly. Repeat percussion until the upper die guide sleeve slides into the correct position by its own weight.

The editor of 　　 Punch Punch reminds you that you can’t use force on the outer diameter of the upper die guide sleeve, you can only use force on the top of the punch. Do not knock the top of the upper die sleeve to avoid damage to the turret hole and shorten the service life of individual stations.
