A rotary punch, also known as a turret punch. The punch in the shop is a "C Frame" style punch and is used to shear holes in materials. The turret would normally contain a variety of punches of different shapes and sizes. The selected punch and die required needs to be properly aligned before use. You can use the laser to cut any shapes needed as the rotary punch does not currently have any tooling. Here is an example of a similar piece of equipment being used.
- Punch- The shaped metal the gets pressed through the working material and removes its shape.
- Die- The material that supports the punch as it passes through the working material.
- Turret- The rotary head of the equipment that holds the punch and dies.
The rotary punch consists of a handle and 2 rotary carousels that house various punch/die sets. The top carousel needs to match the correct bottom carousel to prevent damage to the punch/dies. Always verify the letter on the top and bottom carousel match. Always move the handle slowly when testing die alignment to verify proper alignment. Most dies have an alignment stub to center the die with the material you want to punch.
You will need to demonstrate safely setting up the rotary punch and make a hole or square of your choice.
- You will need to find a piece of 16 gauge or thinner scrap sheet metal larger than the punch you want to use. The material will also need to be large enough to hold onto.
- Drill a hole roughly 1/16" in the center location of where you would like to punch.
- Make sure the handle of the punch is in the up position.
- Pull the carousel release lever towards the front of the machine to allow rotation of the carousel.
- Rotate the top carousel to the desired punch and release the lever while rocking the carousel to verify it has locked in place.
- Lift the bottom locking lever for the lower carousel and rotate it until the top and bottom letters match. This will align the top punch with the lower die.
- When in position release the lower lever and rotate the carousel to verify it has locked into position.
- Slowly lower the punch handle to verify proper alignment of the punch and die. If you feel resistance DO NOT FORCE THE HANDLE. Get help from a supervisor if needed.
- Slip your material into the slot between the punch and dies.
- Align the small center punch located on the end of the punch with the small hole you made earlier in your material. You many need to move the handle to get the punch at the correct height.
- Pull down on the punch handle and you should feel the punch push through the material.
- Pull up on the punch handle to retract the punch.
- You can now remove your material and it should have a hole where the punch sheared though the material.
- Reset the space.
- Make sure to keep your hands and fingers away from all pinch points.
- Always check alignment of the punch and die by slowly advancing the punch handle without material in the machine. If you feel resistance stop and get a supervisor to help you.
- If the punch and die does not appear to be align make sure the lock handles are engaged in the carousel by gently trying to rock the carousel back and forth.
There are several grease fittings located on the machine that need to be greased. The punches also need to be oiled as needed by the technician.
