ISO9001 Lab Test Machine Luggage Zipper Reciprocating Fatigue Testing Machine

Luggage Zipper Reciprocating Fatigue Testing Machine / Width Of Transverse Clamping Device: 25mm​

 

Product Introduction

The zipper reciprocating fatigue testing machine is used to test whether the zipper can withstand the specified number of reciprocating pulling operations under the action of transverse and longitudinal tension. During the test, the zipper pull head is driven by the machine at the same speed, and the machine moves back and forth 30 times per minute until the specified number of times. According to QB / T2171-2001 metal zipper, QB / T2172-2001 injection zipper, QB / T2173-2001 nylon zipper and other standards.

Operation specification

1) . sample preparation:

Random samples were taken from each batch of zippers

2) Operation steps:

1. Sample device:

1.1. After power on, start the "test" button, so that the latch clamping device is located at the bottom of the chute (convenient for clamping the sample)

1.2. (turn off the power), fix the zipper lock on the lock clamping device

1.3. First, fix the zipper tail end (bottom stop end) roughly in the upper collet (at this time, the collet center line is perpendicular to the zipper Center)

1.4. Fix the front end of the zipper (top end) on the two longitudinal clamps

1.5. Slightly loosen the upper collet, pull up the end of the zipper to make the rotating plate in a horizontal line, and then clamp the upper collet (at this time, visually check that the two longitudinal collets are in the same horizontal line)

1.6. Adjust the upper and lower nuts of the spring scale according to the zipper model, and apply appropriate longitudinal load on the zipper cloth belt: as shown in Table 1:

1.7 loosen the two transverse chucks, put the cloth tapes on both sides of the zipper into the two clamps for clamping (at this time, visually check that the two transverse chucks are parallel to the zipper and on the same horizontal line), and there should be a 5.0 mm gap between the chucks and both sides of the chain teeth

1.8. Adjust the upper and lower nuts of the horizontal spring scale according to the zipper model, and apply appropriate horizontal load on the zipper cloth belt: as shown in Table 1:

1.9. Start the "test" button to start the test

2.0. Set the test times according to the test regulations

2.1. After reaching the set number of times, the machine will stop automatically, remove the sample and turn off the power

2.2. Remove the sample and inspect its damage degree
