Apparatus for testing the bending strength of elastomeric materials
Реферат: 1408411 Testing bending strength POLYAIR MASCHINENBAU GmbH 25 Aug 1972 [26 Aug 1971] 39796/72 Heading G1S Apparatus for bend testing elastomeric samples of say shoe sole material comprises a driven shaft vertically reciprocating a con rod 6 and drive arms 7 each arm being attached by a pin 11 sliding in a slot 16 to one end of cross straps 8 the other ends of the straps 8 being guided by pins 9 sliding in slots 10. The straps 8 support plates 15 carrying test material samples 13, and a bar 17 which has a rounded top is connected to the arms 7 and is lifted and lowered to provide a support for each material piece in that portion to be subjected to bending stress. In operation, rotation of the shaft 2 reciprocates the rod 6 and bar 17 and opens and closes the plates 15 carrying the specimens 13. At the same time the plates 15 and samples 13 are raised into contact with counterweighted blocks 20 which apply pressure to the samples 13 at the points where the bars 17 provide support and where each sample 13 is bent.
