1 DieMax XL . Maximum life Springs ISO Inch ISO Metric JIS. R Series DieMax XL Maximum life Springs Since 1923, Danly Delivers Quality Diemakers' Supplies Danly is the leading manufacturer of The Danly Story die making supplies and components for industry in North America. Since Danly incorporated on August 20, 1923, Danly provides high quality 1923. Although the first modern die products and services, innovative sets were used as long ago as the development, and custom products. late 1800s, Danly revolutionized the industry with the guide post die set. The Danly product set includes a wide This set, so named for the feature range of guide posts, bushings, die of the pin entering the bushing to Springs , punches, wear plates and guide the punch holder to the proper cams, and other diemakers' supplies.

2 Position, came into its own as a result We also supply customized products of the tremendous increase in the use to fit our customer specifications. of stampings to meet the urgency of production in WWI. This is the type of One of our goals at Danly is to lead die set which is generally used today. the industry in providing products When Danly was founded, however, that help customers find solutions die sets were still being produced to improve their operations. The in the tool shops of the user, or on development of tapping tools provided special order at job shops . the opportunity for gains in customer efficiency. These tools allow customers Danly brought a completely new to eliminate the secondary operation concept into the manufacture of die of tapping products by allowing sets.

3 This was Danly's now famous them to be tapped in the stamping interchangeability by which Danly operation. die holders of the same center distance are made interchangeable. To maintain our leadership and This method, for the first time, made reputation, we have invested heavily it possible for the die designer to lay in state-of-the-art manufacturing out his dies with absolute certainty facilities. that they would fit in the Danly die set Danly Products specified.

A combination of enhanced raw Physical Dimensions and Load Manufacturing Processes material, optimal spring design, Ratings In addition to the optimal, low- innovative manufacturing processes, Computer controlled coiling and spring stress spring design, the continual and broad distribution channels allow setting equipment allow tight control investment in the most advanced the DieMax XL spring to yield the over the critical spring characteristics.

5 Coiling and spring processing best, most dependable performance Every manufactured lot of DieMax equipment allows Danly to offer a and availability combination, time after XL Springs is carefully inspected for premium, long- life , mechanical spring time. hole/rod fit, free length, spring rate, solution. From the computer controlled solid height, squareness and physical spring coilers with in-line SPC data spring Wire appearance. All inspection results collection, the Springs are routed Danly Springs are manufactured from are recorded and analyzed to ensure through a series of steps including premium spring quality steel. The compliance to quality standards. shot peening to reduce working high tensile strength and superior These tight tolerances and highly stresses, and set removal which heat resistance wire characteristics inspected attributes guarantee the ensures the spring length and load will contribute to the low-stress, long life Springs will work freely over the rods not relax in the tool.

6 spring design. or freely in the holes specified without binding. They also ensure that the free Enhanced Design lengths, solid heights and spring loads Our spring starts with a modified are compatible from spring to spring trapezoidal cross section and and lot to lot for predictable, long- life changes to a D cross section after performance. coiling. This wire cross section has significantly lower stress levels during compression compared to competitor designs. The D cross section also allows for more coils per spring while providing a greater amount of spring travel to solid when compared to competitor Springs . Using the latest in CNC coiling Ends of each spring are closed and ground technology, Springs are produced square to assure that the spring will stand on with much better predictability and either end and provide a Maximum bearing surface.

7 Consistency in performance, rates and lengths. Operators use Statistical Process Control (SPC) software to ensure that every production process meets our Before Coiling After Coiling high quality standards. Modified trapezoidal cross section of spring testers track and verify rectangular wire Springs changes to a D cross section during coiling to achieve a low stress consistency in spring dimensions level that means longer spring life . and rates with custom spring testing software. 4. spring Selection Steps If the diameter and length are known, turn directly to dimension tables beginning on page 8 to select Springs with desired total load. If diameter and length are not known, use the following seven spring selection steps and refer to the rate column of the dimension tables for spring selection.

8 In determining the length of a spring , it should be remembered that Maximum Step 3 Step 6. delivered spring load is obtained by Determine free length C as follows: Inch: Determine R (total rate for all selecting longer Springs . For best Decide which load classification the Springs in pounds per 1/10 inch) by economy and saving of space, choose spring should be selected from: Light, using the following formula: Light and Medium Load Springs or Medium, Heavy, or Extra-Heavy Load. R= L. the Heavy Load spring having a free Then choose the figure nearest the ----------- length equal to six times the travel, or compressed length H required by the 10 x X. an Extra Heavy Load spring having die design from the appropriate charts a free length equal to eight times the on page 6.

9 Read corresponding C Metric: Determine R (total rate for travel. If ratios lower than these are (free length). all Springs in newtons per millimeter). used because of height limitations, by using the following formula: the number of Springs required will be R= L. substantially increased. ----------- X. Step 1 Step 7. Estimate the level of production Select Springs as follows: required of the die - short run, Step 4 1. The free length C must comply constant production, etc. Estimate total initial spring load L with the length determined in Step required for all Springs when Springs 3. Step 2 are compressed X inches or Determine compressed spring length millimeters. 2. Divide R in Step 6 by the number H and operating travel T from the of Springs to be used (if known).

If the number of Springs is not known, Step 5 divide R from Step 6 by the rate of Determine X (initial compression) by the spring you select for the correct using the following formula: number of Springs .
