Rapid T.A.P. Software

Danly-IEM

In-Die Tapping and Cam Driver Design Software

Rapid T.A.P. software aids in the development of dies with Danly IEM in-die-tapping tools. This software is designed to educate die designers and stamping facilities on the benefits of In-Die Tapping (IDT) and provide easy ways to design dies that incorporate the IDT tools.

Rapid T.A.P. screenshot

Rapid T.A.P. produces needed CAD information for the IDT Cam Drivers that are proprietary to Danly IEM tapping tools. Rapid T.A.P.’s program logic evaluates the sinusoidal acceleration that is inherent with mechanical presses and converts it into a linear tapping motion. This conversion is more accurate than altering gear ratios.

Choosing the Proper Die Springs

Dayton ProgressDanly-IEMLaminaLempco

Springs

Extend operating life with well-chosen Dayton Lamina die springs

Die springs, an essential stamping die component, create the optimal pressure for restraining the sheet material in a fixed position while it is being pierced, formed, flanged, or trimmed. The springs also provide controlled return pressure for the die stripper to permit the punches and other die-mounted tools to evacuate the material during the press' return stroke.

Die springs are most commonly used to actuate strippers, but they can also be found behind form pressure pads and binder rings in draw dies. The goal is to provide adequate die spring pressure within the limited remaining space of the die.

Spring Selection Process

Figure 1

To select a die spring, you first should gather information about three different aspects of the die design: how much pressure is needed; what spring size and how many are needed to produce that pressure; and how far these springs must collapse or travel.

Pressure Requirements

To determine spring pressure for a spring used in a stripper, first calculate the perforating pressure for the entire die. To do this, you need to know the thickness and shear strength of the part material as well as the length of shear or cutting distance. These elements multiplied together will give you the perforating pressure. The formula reads:

Perforating pressure = S × T × L

Where:

  • S = Shear strength of the part material
  • T = Part material thickness
  • L = Total length of shear or cutting distance

 

A pressure equal to 10 to 15% of the total perforating pressure typically is used to actuate the stripper (the range accommodates the potential differences among spring manufacturers). This allows for the downward ram speed to align safely and engage the die shoe components into their guided, mated components before material contact.

Spring Stripper

Figure 2

As the ram moves down, the stripper makes contact with the part material and stops. The spring continues to compress, or travel, until the ram reaches the bottom of its stroke.

Stripping pressure = Perforating pressure × 0.10 to 0.15

Although the formula for determining pad pressure in a form die is different from that of a stripper, it must still contain the same three elements of (1) pressure, (2) quantity and size of springs, and (3) the travel. The pad pressure in a forming operation should be at least 1.5 times greater than the force required for bending the part.

Bending pressure = ((S × 0.166 × T2) / (T + R1/2 + R2/2)) × L

Where:

  • S = Tensile strength
  • T = Material thickness
  • R1 = Radius on form punch
  • R2 = Radius on form die
  • L = Length of form

 

Pad pressure = Bending pressure × 1.5

A forming operation requires more pad pressure than a bending operation because of the need to control sheet material movement over the forms and maintain its new shape. The pad pressure also helps to prevent material from scoring or tearing as it is being formed.

Pressure requirements for binder rings in draw dies tend to be less scientific, determined by trial and error. It is not uncommon to find a note on a draw die design stating the spring requirement as "springs to suit."

As the binder ring holds the material in its locating position, the spring pressure required tends to be adjusted to eliminate the tearing and shearing that may occur while the material is being drawn or stretched. A too-high spring pressure will inhibit the drawing of the material, while too little pressure will draw material up the form and fail to provide a uniform wall thickness.

Spring Size and Quantity

The amount of available space in the die will help determine how many springs to use and what sizes to choose. Whenever possible, try using numerous low-pressure springs rather than a few high-pressure springs. This will reduce stress on the springs.

As long as the tool layout permits the necessary space, more springs of lower pressure allow for more evenly distributed pressure and a more balanced stripper pad. This enhances sheet material control throughout the complete press stroke. Also, if just one die spring becomes fatigued, the die pad will continue to operate with the other springs.

Die spring placement, when applicable, should be nearest the area being pierced, formed, flanged, or trimmed. This enhances the ability to locate the most pressure on the area being worked upon while maintaining sheet material control. The use of spring cams, retainer bolts, or spring pockets serve to guard the springs from debris and protect the tool die details in the event of a fatigued or broken die spring.

Travel Requirements

When springs are installed in a die, they are compressed approximately 0.125 inch. Called preload, this compression is necessary to keep the springs from working their way out of the die. As a side benefit, the preload reduces the shock associated with rapid loading and unloading of the die and increases the spring life.

Figure 3

The bottom of the stripper draws up just short of being flush with the end of the punch. This ensures that the part material strips completely off the end of the punch. When the press cycle starts, the ram begins to move downward. The stripper makes contact with the part material and stops. As the ram continues descending, the springs compress, allowing the punches to extend through the part material and into the die button until the ram reaches the bottom of its stroke. This compression is called stripper travel.

The travel of a spring is determined by the spring preload, thickness of the material, entry of the punch into the die button, and the distance the stripper hangs below the bottom of the punch. Put simply, preload plus the stripper travel equals the total spring travel.

The same is true in form and draw dies. Pressure pads or binder rings will also travel and compress the springs. Preload plus travel of the stripper or comparable component will give you the total travel of the spring.

To reduce stress and allow for maximum spring life, you should keep preload and travel to a minimum. The more rapidly a spring works in compressing and decompressing, the greater the fatigue factor. Slower-spring applications permit longer spring travels, longer spring life, and the ability to operate near maximum spring deflection levels. The faster a die spring cycles, the shorter the spring life expectancy. In such fast cycling applications, you should lower the spring deflection.

Spring Selection

Now that you know the pressure, approximate size, and travel, you can begin the actual spring selection process. This starts by combining the three aspects of the die design. First, divide the total stripping force required by the number of springs to be used.

The selected spring must deliver the desired pressure at preload. To determine the pressure of the spring at a given preload, multiply the amount of preload by the amount of pressure the spring develops over one inch. Most spring catalogs give pressure ratings over one inch as well as various other amounts of compression or travel.

Keep in mind that the spring must offer sufficient travel within its normal operating range. For example, the maximum operating range of a medium-pressure spring is approximately 50% of the free, or static, length. The efficient operating range of this spring is between 10 and 35% of the free length. Higher-pressure springs will have a shorter range of travel.

Although springs will compress beyond the maximum operating range, you should avoid this at all cost. Compressing beyond maximum range will severely hinder spring life and could damage the die. It is also a good idea to choose a spring with extra travel to prevent over-traveling the spring after a tool has been re-sharpened.

Tough Under Pressure

Whatever your application might be, you can be sure that die springs from Dayton Lamina provide rugged, dependable performance. The brands of Dayton, Lamina, Danly-IEM, and Lempco offer a wide selection of NAAMS, ISO, and JIS standard springs.

NAAMS Automotive Pins

Danly-IEM

NAAMS guide posts are manufactured in accordance with the North American Automotive Metric Standards. They are manufactured from high quality hardened steel and finish ground for a high precision finish. Hardness is RC 57-62 with a minimum depth of 0.8 min. These posts are ideally suited for the self-lubricating NAAMS bushings.

To reduce tooling weight, the 100mm and 125mm diameter posts, NPH series, are manufactured with a through hole.

NAAMS Automotive Bushings

Danly-IEM

Demountable NAAMS bushings are self-lubricating and are available in guide post and pad styles. These bushings fully conform to the NAAMS, GM, Chrysler and Ford standards.

Self-lubricating bushings contain graphite plugs which are impregnated with oil. When the bushings reach 80-90°F as a result of friction between the bushing and guide post, oil is drawn from the plug, thus lubricating the wear surface. A dark smear pattern is created on the wear surface as the oil and graphite are embedded into the bronze or steel grain. This provides the lubrication necessary for continuous performance of the tool.

 

NAAMS Automotive Wear Plates

Special Die Springs and Heavy Duty Compression Springs

Special die springs and compression springs can be manufactured to your specifications. Our special compression springs can be manufactured to your choice of material, size, tolerances, and coatings. We can manufacture to military specifications. We will provide special inspections, certifications, and testing as required.

Special Wear and Guide Components

Our ball-bearing retainers and flat wear and guide components can also be supplied as specials. See our Specials Capabilities flyer for more details.

If one of Anchor Lamina's standard components is not suited to your application, we can manufacture a special to meet your exact needs. Our standard components can be modified to suit or we can create a new part to your exact requirements.

Specials can be manufactured outside the diameter and length size range normally found on our standard products. Our special components can include any standard product feature. Additional options can include surface finish, coatings, special materials and welding processes.

We offer a two-week turnaround on made-to-order special pins and bushings. Please give us an opportunity to quote to your requirements.
