Compound stamping dies are made with the help of compound die design. This die is made to carry out several tasks with each press stroke and they are used for cutting operations like blanking and piercing. Due to their ability to do tasks more quickly than simple stamping dies, compound stamping dies are more appropriate for intricate or difficult jobs.

Progressive tool stamping is ideal for long production runs due to its high repeatability. A single machine with multiple die stations is used in this metal stamping method. Each station where a stamping operation is performed automatically moves a metal strip of stock material. The finished part must then be cut free from the strip as the final step.

Compound tool and Progressive Tool Process

Compound tool and progressive tool offers a cost-effective and efficient method for producing large-volume runs by utilizing a progressive die. The die contains several stamping stations that perform unique forming operations as a strip of sheet metal is fed through the machine. Combining the necessary stamping tools into one die set improves the efficiency of the stamping project.

 

The following components are essential to a progressive die:

 

❆Die Set

❆Die Buttons (bushings)

❆Punches

❆Punch Holder

❆Plate (section)

❆Pins

❆Slug Clearance

❆Stripper

Compound tool and progressive too may also include features such as sub-liners, stop blocks, slides, or sensors. The primary goal of these components is to ensure accurate handling of the material.

 

Progressive metal stamping follows these steps:

 

The progressive die is positioned inside a reciprocating stamping press.

The press moves up, bringing the top die with it and allowing the metal strip to feed into the equipment.

When the press moves downward, the die closes to execute the stamping operation.

A finished part is released from the die with each stroke of the press.

The final cutoff station separates the finished parts from the conveying web.

Definition and Process for Compound Tool?

Compound Tool Stamping differs from Progressive Tool Stamping in completing multiple operations – such as cutting and forming – in a single stroke. This method is akin to a chef performing several cutting tasks in one swift motion.

It's particularly effective for producing flat parts, where multiple features must be added simultaneously. This single-stroke approach ensures high precision and alignment, making it ideal for parts with paramount dimensional accuracy.

 

Advantages of Compound Tool Stamping?

The primary advantage of Compound Tool Stamping is its precision. Since multiple operations are executed in a single stroke, the risk of misalignment between processes is minimized, resulting in highly accurate parts.

This method is also efficient for producing flat components, as it reduces the number of hits needed compared to other methods, thereby speeding up production.

Additionally, Compound Tool Stamping tends to generate less scrap material, contributing to cost savings and environmental sustainability.

Disadvantages and Limitations of Compound tool

The limitations of Compound Tool Stamping include its lower production speed than Progressive Tool Stamping, as it's generally used for more detailed and precise work rather than high-speed mass production.

Moreover, there are better methods for complex parts that require multiple bending or forming operations. The complexity and depth of parts that can be produced are limited, which means this method is best suited for simpler, flatter components.
