I'm using a "french" stop. I don't know what else it's called, but I'm sure there are a lot of names for the same thing. This type of stop cuts a step out of the material the exact length as the progression and there is a corresponding hard point for it to stop against. Having finished my layout, I know how big the die shoe needs to be and what kind and size of punches to order.
Buying die shoes and punches fall into the category of old machinist wisdom that tells you not to build anything you can buy cheaper. Yes, I "could" make a die shoe and punches, but this place specializes in building them and therefore it is cheaper than me making one. This set of photos show the process of adding features to the die block. Tapped holes in the corners for mounting to the die shoe.
Reamed holes for dowel pins so that the die can be taken apart, serviced, and reassembled correctly. The pierce holes that create the holes in the part, and the pocket for the stamp that adds the art.
Other holes are start holes for the wire EDM work that happens after heat treat. The most exciting part of this process is the heat treating.
Exciting because of the opportunities for bodily damage! I used A2 tool steel for this project for many reasons. The main one is that it's my favorite. O1 is a different story, and I don't tend to use it much anymore. A2 is also more dimensionally stable through heat treat, but I consider that a bonus and not the main selling point.
Step 2; Pop the package in the furnace, set to degrees Fahrenheit, and wait a couple of hours. Step 4; When it's cool enough to handle, remove the foil and put back in the furnace set to degrees and leave it for a couple more hours. This is the step called "tempering". Wire EDM is a specialized process that I don't have in my shop. It's worth paying for in the time and quality that you gain.
This video is a good explanation of the process, but the company that produced the video is not the one I use. No recommendation implied. Mounting the die block to the die shoe is a straight forward process of transferring the location of the tapped holes in the die block to the die shoe. There are a number of ways to do this. Concave jig attachment for lathe. Pneumatic injection moulding die machine. Fabrication of electromagnetic moulding machine. Design and analysis of press tool machine.
Design and fabrication of tool cutting force dynamo meter on lathe. Tool and die design for progressive tools. Fabrication of pneumatic bell crank press.
Eccentric punching die machine. Auto Indexing gear cutting attachment for pneumatic shaping machine. Vacuum bag moulding die machine. Tool and die design for combination tools. Tool and die design for machine mould. Fabrication of pneumatic pellet Press. Tool and die design for forming.
