The different dies should be used for fabricating different workpieces. You need to know the fabrication parameters of the press brake machine as well as the die very well, then it is possible for you to choose the right press brake die to match each other.The parameters of press brake including stroke, working ability, daylight (open height),middle plate type.<\/p>\n

Press brake die height formula<\/strong><\/p>\n – Stroke (mm)=daylight – middle plate height – upper die height – lower die height -(lowerdie height – 0.5V+t) t = plate thickness (mm)<\/p>\n

(83-t)mm<\/p>\n Note: 0.5V < stroke < max stroke<\/p>\n Please note the lower die base also have many different heights, which is used fordifferent fabrication purpose.So don’t forget this when choosing lower die base.<\/p>\n Different tool & die cluster can obtain different combined height for different fabricationpurposes of parts.<\/p>\n [\/fusion_text][fusion_text columns=””

die should less than the fabrication angle.<\/p>\n For example, if the workpiece’s bending angle is 90\u00b0 , you should choose the die with 88\u00b0 tipangle.<\/p>\n Lower die type<\/strong><\/p>\n Generally, the lower die has a single V type and double V type, among which it is separatedinto the separated die and full-length die.<\/p>\n The different die is applied to a different fabricating purpose.<\/p>\n However, the single-V die has a much wider application than double-V die, while theseparated die is more widely used than full-length die.<\/p>\n Lower die V width (die opening), V
