b"Selecting a READYHYDROCAMSystemHow To Select a HYDROCAMSystemfor Your ApplicationBasic Selection:1. Determine tonnage required (piercing or forming force, plus stripping force), per unit to perform the necessary work.Note when using urethane or other mechanical methods for stripping, please add the appropriate stripping force.2. After you calculate the forces, select the correct H-2 unit(s) required to do the work. Do not exceed 90% of the H-2units available de-rated force (rated force, less return system force) from the chart below. Include the proper strokelength needed for each unit (see pages 6 and 7 for available stroke lengths).3. Determine the correct size and number of H-1 pump(s). Group identical H-2 units together (tonnage and stroke),performing identical work (piercing, forming of flanging). One H-1 pump can operate up to four identical H-2piercing/forming units (see chart on page 5).Force of H2 Piercing/Forming UnitThis chart shows the effect of a nitrogen or oil return H-2 Model Model Model Model Model Model Modelsystem on the force rating of each H2 unit. 2 3.2 5 7.8 12.5 20 31Standard Rate equals the effect of standard daN 1,787 2,885 4,545 7,094 11,319 18,819 28,817(minimum) return force at 100 bar (1,450 psi) on Std.

We selected a 25mm stroke length for this example. (The working example uses piercing asthe HYDROCAM application. HYDROCAM is also ideal for forming, flanging and other applications.)Step 1 Calculate the force.Force = (HoleX ( = 3.1416) X material thickness X material tensile strength) + recommended 10% stripping forceEnglish example:(.250 in. X 3.1416 X .125 in. X 50,000 psi) + 10% = 4,909 lbs. + 491 lbs. = 5400 lbs. ( 2000 lbs. = 2.7 U.S. tons)Metric example: (6mm X 3.1416 X 3mm X 40 daN per mm 2 ) + 10% = 2,262 daN + 226 daN = 2,488 daN ( 1000 N = 2.5 metric tons)Step 2 Select the rate.
