Overview

Perce 91179 double punch, composed of two punches clamped by Perce 95151 servo double punch holder, can choose V punch, flat punch, round punch, needle punch, ER round punch to achieve combined punching and cutting. It can punch leather, imitation leather, PU, PVC, EVA, SBR, cloth, cardboard, kraft paper and other materials.

The double punch drives the two main shafts to rotate synchronously through the motor with synchronous belt transmission; there is a rotary limit switch to accurately control the required punching angle.

Installation Dimensions

Instructions for use and debugging

（1）Installation and debugging

Fix the Perce 91179 double-head punch on the equipment mounting plate with 5 M5 screws. The installation height should be no higher than 20 (+1~+5) mm from the work surface. Connect the motor correctly and connect the cylinder to the air pipe. Depending on the punching effect, the stroke adjustment nut can be fine-tuned appropriately until the best punching effect is achieved.

（2）Punch installation and removal

Align the guide groove with the positioning pin and insert it into the connection, then use a hexagonal wrench to tighten the screw.

Connect the punch to the double-head punch, rotate and tighten, and then use a hexagonal wrench to tighten the top screw.

Punch removal: Be careful not to clamp the drive shaft to remove the punch, but fix the flat position of the wrench and remove the punch.

（3）Oiling and maintenance

Lubricating the guide rails at regular intervals can reduce wear on the guide rails and make them work better.

（4）Synchronous wheel installation distance

The reference surface to the synchronous wheel is 8mm; please measure the actual dimension B, therefore, C=A-B, and install the control distance C to ensure the parallelism of the synchronous belt.

Precautions

1. Before powering on, make sure the wiring is correct

2. The incoming air pressure is not higher than 0.6MPa

3. Clean and dry compressed gas must be connected. (For example, use a pneumatic triplex to filter, reduce pressure and add oil to the gas to ensure the normal operation of the pneumatic actuator and prevent malfunctions due to impurities, excessive air pressure or lack of oil.)
