Description
Technical field
What the present invention relates to is the composite die in a kind of detection technique field, specifically is a kind of stretching punching reaming composite die that is used to detect sheet material reaming performance.
Background technology
State Standard of the People's Republic of China's " the metal sheet profiled performance of GB/T 15825.4-1995 and test method/hole expansion test " has provided the universal method of carrying out the sheet material hole expansion test, during this method test, the sample that the center is had a prefabricated circular hole places between die and the blank holder and compresses, by punch the sample material of its underpart is pressed into die, prefabricated Circularhole diameter is constantly swollen, ftracture until the peritreme part, stop the punch motion, measure the maximal value and the minimum value in sample aperture, calculate the reaming performance index of hole expansibility as sheet metal with them.
According to the sheet metal thickness difference, the prefabricated Circularhole diameter that is adopted is also inequality.Standard is divided into three thickness range: 0.20～1.00mm with sheet material, 1.00～2.00mm, 2.00～4.00mm, for 0.20～1.00mm, 1.00～2.00mm thickness range treat the punching plate, can adopt the prefabricated circular hole of three kinds of diameters.During test, preferentially adopt prefabricated Circularhole diameter maximum in this thickness range, when peritreme does not ftracture, get less a kind of prefabricated Circularhole diameter successively and change its corresponding pilot pin.For 2.00～4.00mm thickness range treat the punching plate, adopt a kind of prefabricated circular hole of diameter.
Find through retrieval prior art, Deng Ming, Xu Hongbin and Liu Fengzai " magnesium alloy plate bulging and reaming performance study " (forging technology, 2004, a kind of expanding method is disclosed 4:33-36), on sample, process the prefabricated circular hole of the maximum gauge in the pairing thickness range of sample thickness, on the forming test machine, carry out hole expansion test then.Every kind of test material of standard-required need be finished effective revision test 10 times, therefore will prepare the sample more than 10 at least.If peritreme does not ftracture, then also need prefabricated circular hole than minor diameter, test again.For needing prestretched to carry out the test of ream operation again, also need independent drawing die.The shortcoming of prior art is: need to adopt many molds, sometimes even need two complete equipments; If peritreme does not ftracture, might cause the waste of specimen preparation material resources manpower; Since need many molds, the test operation complexity, and the cycle is long; Under many circumstances, also can cause the delay of duration.
