fish plate bolts are special equipments used to complete the tear test of ferrite steel drop hammer. Powerful software analysis function, give a variety of data processing results: preset energy, impact energy, absorption energy, impact speed, impact time, etc. And can automatically generate test report. So how do you use fish plate bolts?

How to use fish plate bolts

1. Before the test, replace the appropriate pendulum according to the requirements of the striking energy.

2. Turn on the power switch of the body, press and hold the operator to make the pendulum empty (no sample). Check that the dial's passive pointer points to zero. If it does not point to zero, adjust the pointer position so that the pointer is zero when it is empty.

3. Place the pendulum on the edge of the support with a wooden block, and use a notch centering template to make the notch of the impact sample in the center of the span of the support, and the notch surface on the impact drawing side.

4. Press the "Start" button and lift the pendulum. After the pendulum reaches the set height and stabilizes in place, clear all obstacles in the impact circle of the pendulum of the wooden board machine and move the dial pointer to the impact energy scale.

5. Press the "Impact" button and drop the hammer to break the sample. When the pendulum swings back, press the brake button. After the pendulum stops swinging, the impact energy is recorded. After the test, turn off the power supply of the operator and fish plate bolts, and hang the operator back to the original position.

Attention:

1. Do not bend over to place the sample after the pendulum is lifted; During the test, no human activity is allowed in the swinging plane of the hammer.

2. When the sample breaks, the pendulum swings back and forth, press the "brake", the still swinging fish plate bolts pendulum can not be stopped by hand.
