What is the progressive die?

What is the progressive die?

: a compound tool used in a punch press for performing several operations (as drawing, punching, bending) in a single movement or in as few as possible successive movements.

How do progressive dies work?

The progressive stamping die is placed into a reciprocating stamping press. As the press moves up, the top die moves with it, which allows the material to feed. When the press moves down, the die closes and performs the stamping operation. With each stroke of the press, a completed part is removed from the die.

How much does a progressive die cost?

Progressive die costs range from under $10,000, to upwards of hundreds of thousands of dollars, and are most dependent on part size and complexity.

What is progressive die and compound die?

Compound die stamping is used for making simple flat parts such as washers. A strip of metal is fed through the compound die, but unlike progressive or transfer die stamping, compound stamping tooling performs multiple cuts, punches, and bends in one stroke rather than multiple strokes.

What bending dies?

Bend dies, clamp dies, and pressure dies are the minimum essentials for bending tube and tube forming. Each of these types of dies performs a function. A clamp die will hold the tube in position while it is being bent. A bend die prevents the tube from flattening and forms the radius of the bend.

What are die charges?

Die charges are service fees In the event there are reorders for a period of two years, we reserve the right to dispose of dies.

How much does it cost to make a die?

Pricing. Die prices range based on precision, complexity and size, but most dies cost around $100.00 – $150.00. Larger dies or “up dies” that require special bracing or material can cost upwards of $500.00. The lead time for a die to be manufactured is about 1 week or 5 business days.

What is blank die?

Blanking: A blanking die produces a flat piece of material by cutting the desired shape in one operation. The finished part is referred to as a blank. Generally a blanking die may only cut the outside contour of a part, often used for parts with no internal features.

What is Progressive tool?

A progressive tool is an alternative to the transfer press. Progressive tools are designed for the processing of strip material. This is pushed further through the tool by an upstream uncoiler and a precise strip guide with each stroke. The product is processed consecutively at successive processing stations.

What are transfer dies?

Transfer dies can include a single die, a number of dies, or machines arranged in a row to form a production line. The transfer press process begins with a strip of metal fed into the first station where the blank is cut. The blank is then transferred mechanically(or manually) through various forming stations.

When do you need to use a progressive die?

Progressive Dies. Progressive dies are used more for higher volume parts needing to run automatically at high rates of speed (strokes per minute). Normally the parts tend to be smaller, but there are also larger part applications as well.

How is lift eliminated in a progressive die?

If all forms in a part are in the same direction, lift can be eliminated by forming upward. This usually adds to the cost of the die. When the part has forms in opposite directions, compromises must be made among excessive lift, poor material use, and the complexity and cost of the tooling. One such compromise is shown in Figure 2.

What are the critical dimensions of progressive dies?

For example, Figure 1 shows a part for the computer industry that was rotated in the strip to guard against inconsistent form angles that could be caused by differences between coils. The part contained critical dimensions with 0.025-millimeter tolerances dependent on the forms.

How does a progressive die stamping process work?

Progressive Die Stamping. Progressive die stamping consists of several individual work stations, each of which performs one or more different operations on the part. The part is carried from station to station by the stock strip and is cut out of the strip in the final operation.
