Embodiment Construction
[0020] Take the production of a buffer spring as an example to describe the method in detail below:
[0021] The structural parameters of the spring are shown in figure 1 , the pitch of the spring is 29mm, and the section thickness is 23.8 0 +1.5 mm, outer diameter 47 -0.25 +0.2 mm, inner diameter 18 -0.2 +0.6 mm, the finished product length H 0 for 276 -2 +1.5 mm, height H of working start state 1 262mm, pressure P 1 26KN, height H at the end of work 2 238.5mm, pressure P 2 73±2KN, spring pressure and height H j : 217mm; corresponding pressure P j 156KN
[0022] First, the first compression height of the spring should be calculated according to the prefabricated height HI of the spring, and the next compression amount of the spring should be determined according to each compression situation, and the compression amount and the corresponding pressure P′ and height H′ should be calculated, see Table 1 :
[0023] Table 1: List of buffer spring short pressure tes...
