Marsh Mellow Die Springs - Anchordanly
— Marsh Mellow Die SpringsMADE IN AMERICA1
The Lamina Marsh Mellow Die Spring is aproven cost saver for the metal stamping industry.Marsh Mellow Die Springs can be used as amaintenance free replacement for costly selfcontained nitrogen cylinders. The unique construction elements are the secret of the springdesign flexibility.The solid rubber core with hollow center and biasply fabric wrap are combined to meet special loadand performance requirements. When designedinto proper applications, Marsh Mellow DieSprings can give up to and greater than 1 millioncycles of life.To select the proper diameter.TO DETERMINE MAXIMUMFREE HEIGHT:DeflectionMarsh Mellow Die Springs may be safely compressed to 27.5% of their free length. Operatingwithin a 27.5% compression range will increasethe life of the springs. Any deflection greater than27.5% will greatly reduce the life of Marsh Mellow Die Springs.To select the proper diameter, free length, andquantity of Marsh Mellow Die Springs requiredfor your application, refer to the following examplesor contact a Lamina representative.Spring RatiosThe spring length should not be less than 1.2times the O.D. and not more than 1.7 times thespring O.D. (i.e. a 2" O.D. spring would rangebetween 2.4" to 3.4" length for optimum life.Consideration should be given to the cycle rate.Cycle RateMarsh Mellow Die Springs may be compressed upto 27.5% of their free height based upon the followingC.P.M.

Temperatures above 63 C (135 F) willreduce the part life.StorageLight and heat affect the storage life of rubbersprings. We recommend storing Marsh Mellow DieSprings in low light and temperatures under 63 C(135 F).Fluid CompatibilityWater Based Lubricants–Marsh Mellow DieSprings are compatible with most water based fluids.Certain additives, however, can attack the compoundand shorten life.Petroleum Based Lubricants—Marsh Mellow DieSprings are resistant, but not 100% compatible withpetroleum based fluids. Occasional contact shouldnot affect the part.With either type lubricant, drains should be used toprevent fluids from pooling around parts.The active life of Marsh Mellow Die Springs is3–5 years depending on environment and cycletime.

The sameattention must be placed uponthe surface on which the springscontact top and bottom. MarshMellow Die Springs free lengthshould not be more than 1.7 timesthe diameter and not less than1.2 times the diameter. For addedlength, springs may be used with aguide rod or stacked with locators.(Stacking of springs does not increaseforce but increases total deflection.)See Figures 3 and 4 on page 12.LOADS AS A PERCENTAGE OF DEFLECTIONActualO.D. x I.D.Inch1-1/8 " x 5/16"1-5/8" x 5/8"2" x 3/4"2-1/2" x 3/4"3-1/4" x 1"4" x 1"5" x 1"6" x 1"mm30 x 840 x 1650 x 2063 x 2080 x 25100 x 25125 x 25150 x 2510%15%20%25%30%Pounds Newtons Pounds Newtons Pounds Newtons Pounds Newtons Pounds 042612129505760217620783743

Installation Instructions1. Hole or Pocket SizeMarsh Mellow Die Springs were designed to insure proper fit in specificsize holes or spring pockets. Insure that the hole or spring pocket is theproper size and that the Marsh Mellow Die Spring is centered. See bulgecurve on page 3.ThreadBody2. Locating StudThreaded studs can be used as locatorsThreaded Studs Available(Press-fit) into Marsh Mellow Die Springs to order ad suffix “T” i.e. for 2"80mm3"Locating Stud*Metric studs will be used with metric sized Marsh Mellow Die Springs unless otherwise requested.Regarding installing studs in Marsh Mellow Die Springs:The body length of the stud should never exceed 50% of the Marsh Mellow Die Spring free length.If such a condition does arise, the stud must be altered to allow for compression.STACKING3.Using LocatorsLocators can be made from washers andshould fit closely around the rod. O.D. pocketmust accommodate bulge growth.4.Using Guide RodsGuide rods are recommended when stackingMarsh Mellow Die Springs.Guide rods, washers andsleeves are supplied bythe die maker.Double Locator tobe supplied by thedie maker.Locators and guide rodshown in aqua12
Application RequirementsConsiderations for the selection of individual Marsh Mellow Die Springs1 Determine the force required to blank, form, hold or strip thepart. Remember–die design is an art, not an exact science. Attimes more force may be necessary than originally calculated.We recommend an upward adjustment over determined force(this allows for the set that a spring will take over it’s lifetimeand any additional friction).2 Determine the working stroke required to make the part.3 Determine the die open clearance.4 Determine the working area.5 Determine the strokes per minute.Application Ideas:Marsh Mellow Die Springs are designed to replacecertain standard size coil die springs and nitrogencylinders.1. Die storage blocks. SEE EXAMPLE 12. Running storage blocks (which will balance unevenpress ram thereby improving part quality).3. Floating upper shoe on blank dies (improving quick diechange). SEE EXAMPLE 24. Floating punches on inverted stretch draws (replacingnitrogen cylinders).6 Determine if there are restrictions on the outside diameters(because of the bulge–expansion of the spring when compressed (see the bulge curve on page 3) due to restraints,interferences, flat and smooth mounting/striking surfaces, etc.Please Note:7 The Marsh Mellow Die Spring is made from a RubberCompound–its physical properties deteriorate over time.Depending on temperature, light, ratios, deflection, cycle rate,etc. the spring begins to diminish after three years of life.Heatis an enemy of rubber, either heat generated from compressionof the spring or operating environment temperatures.The active life of a Marsh Mellow Die Spring is 3 – 5 yearsdepending on operating conditions.In addition, the larger diameter parts can exert forcesfrom 1900 to 155,000 newtons (Lbs.) each, and are anextremely effective alternative to costly nitrogen cylindersas in CAM returns.5. Cam returns. SEE EXAMPLES 3 & 46. Die springs (on pads eliminating costly spring pockets).7. Pressure control on trim, flange and form dies.8. Replace nitrogen modular press cushions on OBIpresses.EXAMPLE 1EXAMPLE 3Marsh Mellow Die SpringsRequiredMarsh Mellow DieSprings RequiredPlan of Die Form Up and DownPlan of Die Cam FlangingEXAMPLE 2EXAMPLE 4Marsh Mellow Die SpringsRequiredMarsh Mellow DieSprings RequiredPlan of DiePlan of Die Stretch FormNote: Storage Blocks to be spaced as far apart as practical.Cam Returns are an excellent application for Marsh Mellow Die Springs. As the MarshMellow Die Springs eliminate the sometimes awkward long coil springs required toproduce enough pressure to return the cams13
