|.250" of daylight||Under no circumstances should there be more space between the top of the Die Safety Block and the die, or between the top of the Die Safety Block and the slide if the die is absent. It is absolutely critical to accurately calculate the needed Safety Die Block length. An opening greater than .250" changes the force of a moving slide from static to dynamic.|

|Determining Length of Fixed Safety Blocks||1.Find stroke of the press. 2.Depending on how block is to be used: With die open (stroke up), measure either the space between the upper and lower die OR the space between the slide (RAM) face and the bolster at the point where the block(s) would be placed. 3.Add (1) and (2) together ~ TOTAL (Also when measuring, consider that the slide is adjustable.) 4.If wedges are to be used, subtract 1½" maximum. (This is allowance for variation in the stopping point of the crank shaft.) 5.If end caps are ordered, subtract the end cap allowance for the desired size of block. SB-1 1¼" - SB-2 1¼" - SB-3 1½" Add/subtract as directed and the result will be the safety block length to order.|
|Determining Static Load Capacity of Safety Blocks||A.) Determine the Safety Block Length (1) With the die open (top of the stroke), measure the space between the upper and lower die plates or (2), alternately, measure the space between the slide (ram) face and the bolster plate. "Top of the stroke" generally refers to shut height plus stroke. This provides the maximum height of the safety block. (2) The shut height will generally provide the minimum height of the safety block to be used. (3) These measurements can often be used for the upper and lower limits on and adjustable block. B.) Determine the Static Load that is to be Supported by the Safety Block (either standard or adjustable screw blocks) (1) Add the total weight of the slide (RAM) assembly plus upper die and all components. (2) Multiply this number by two (2) for a safety factor. (3) The resulting figure is the amount of static weight that the safety block(s) will have to support. C.) If static load of the ram and top tooling is unknown, calculate an approximated static load using the following formula. This method contains a built-in safety factor of two (2). press bed area (square inches) X shut height (inches) = total static load (in tons) 1728 (cubic inches in  cubic foot) D.) Refer to the size safety block that should be used for load by using the product data sheets.|
