JSX-1009 Rubber fatigue cracking testing machine for Rubber
vulcanized or thermoplasticDetermination of flex cracking and crack
growth
Overview:
The rubber fatigue cracking test machine is used to determine the
cracking performance of materials such as vulcanized rubber and
rubber shoes after repeated bending, and meets the requirements of
GB/T 13934 "Determination of flexural cracking of vulcanized
rubber" and GB/T13935, GB/T3901, GB/T4495, ISO132, ISO133, etc.
Digital setting, display of bending times, automatic shutdown,
integrated design of host and electrical control, each sample can
be individually clamped, with beautiful appearance and convenient
operation.
Structure Overview:
This machine is mainly composed of a motor base, sliding column,
upper and lower clamps, eccentric wheel mechanism, and digital
display control box.
There are two sliding columns on the base, and upper and lower
clamps are connected to the sliding columns. The position of the
upper clamp can be adjusted arbitrarily, and the lower clamp is
connected to the eccentric wheel connecting rod. The motor drives
the eccentric wheel to rotate, and the lower clamp can perform up
and down reciprocating motion. The front of the eccentric wheel has
an adjustable scale, which can be adjusted according to the needs
of the test. The digital display control box can set and display
the reciprocating frequency of the lower gripper.
Main technical specifications:
| Lower gripper reciprocating frequency | 300 ± 10 times/min |
| Adjustable maximum distance of upper and lower clamps | 200mm |
| Eccentric wheel adjustable maximum distance | 50mm |
| Maximum reciprocating stroke of the lower gripper | 100mm |
| Number of test groups | 6 groups |
| Power supply voltage | AC380V ± 10% |
| Dimensions | 740 × 450 × 950 mm |
| Weight | 180kg |
Configuration List:
1. 1 Allen wrench (14)
2. 1 set of sample clamp (installed on the machine)
