Shoe bend testing machine for testing bend angle

Author:QINSUN Released in:2023-08 Click:108

The shoe bend test machine is a test equipment independently developed and produced by our company qisnun Precision Electromechanical Technology Co., Ltd. This is a cost-effective and comprehensive after-sales service. It is used to test the overall flex resistance of footwear in dry and wet environmental conditions. The sample is installed on the testing machine, and the forefoot is bent at a certain angle and a certain frequency to simulate the walking state of the human foot wearing shoes, and the fatigue resistance and lifespan of shoes are measured.

Applicable standard:

Satra TM92 & 77

Main parameters:

1. Bending angle: 30°, 45°, 60°, 90°

2. Testing speed: 100±5 C.P.M

Operation steps:

1) Observe the sample, if there is any debris, wipe it with gauze and alcohol.

2) The exThe device sample is an experimental foldable shape with proper specs, and the last size should be 5mm smaller than the shoe size.

3) The sample is clamped in the holder, and the metatarsophalangeal flexion of the sole of the shoe coincides with the axis of movement of the holder (if there is a cut, the cut must be on this axis).

4) Adjust the eccentric distance of the testing machine so that the bending angle reaches the specified angle under the experimental conditions.

5) The testing machine is in the state of the minimum bending angle, observe the position of the heel of the shoe, so that the sample is in a natural state without bending in any direction, otherwise adjust the tilt angle of the bracket so that it is in Adjust the bending angle after the natural state.

6) Put the testing machine into the bending angle state, cut a 5mm long incision in the middle part of the la metatarsophalangeal flex portion on the surface of the sole and cut through the sole.

7) Clear the test machine counter, preset the number of bends and bend frequency to the specified value, start the fan, then turn on the host.

8) Check the clamping condition of the specimen. In case of play or change of bending position, stop the machine in time for adjustment.

9) After the testing machine is stopped for the preset number of times, use the vernier caliper to visually measure and test the changing environment of the sample.

As an enterprise integrating R&D, manufacturing, sales, training and service, Shanghai Fanbiao Textile Testing Technology Co., Ltd. is committed to providing more test instruments to the market, long-term supply of textile, leather, Combustion test instruments, automotive interior materials, aging.Environmental climate ment, masks and protective clothing, etc., can also accept non-standard customization.
