Summary of disc feeder test

disk Feeder Test summary
 
1. Steel and process for plate spring test of disc feeder:
 
60Si2Mn spring flat steel with composition (%): C 0.6T, si1.tb, Mn 0.76, P 0.026, s 0.006, Ni < 0.1, Cr 0.18, The heating time of the billet is 980 mm / 980 mm and the heating time is 60 minutes It is carried out on a 400 mm single housing double roll mill. The speed change rate of the leaf spring of the disc feeder is 80 m / min. the deformation is completed in one pass. The quenching hardness is greater than i-irc60, and the tempering is carried out in the usual% plate clamping and straightening mode. The tempering equipment is rjx-4i-9 box type electric furnace with water cooling after tempering,

2. Mechanical properties:
 
1) tensile test: the plate-shaped 6-fold tensile samples with different thicknesses were carried out on a 100 ton tensile testing machine made in Germany. The test results of the disc feeder leaf spring are listed in the table.
 
The fatigue test was carried out on the plate with the maximum fatigue load of 60 mm and the maximum fatigue load was 10.0 mm The results of the fatigue test of T: and T: are shown in Fig. 1
 
In addition, the fatigue life of a single piece was compared on the leaf spring of ameler high frequency fatigue disc feeder in Switzerland. The polished plate specimen with the size of} e.6x26x120 mm was used, the three-point bending loading was carried out, the fulcrum distance was 105 ‰ and the vibration frequency was 60 Hz.
