1、 Foreword of electrical casing bending tester
 & Nbsp& Nbsp Electrical bushing bending tester is applicable to the bending test of insulating electrical bushing and other materials
The total bending angle is 180 & deg;, After the test, observe the sample for cracks
Comply with GB / t14823 2 special requirements for conduits for electrical installation - rigid insulating material flat conduit, JG / t3050 insulated electrical conduits and accessories for buildings and zbg33008 polyvinyl chloride plastic corrugated conduit, etc

The electrical casing bending test can test three kinds of conduits specified in the standard on one equipment, and there is no need to replace the forming die and bending roll
And the operation is convenient, intuitive and reliable
Therefore, it is more and more widely used

3、 Structure description of electrical casing bending tester
It is composed of base, support, forming die, bending roll, clamping device, etc
4、 Operation of electrical casing bending tester
4
1 place stably and wipe the surface clean

4
2 before the test, first insert the bending auxiliary part into each sample
The bending auxiliary part can be a dense coil spring wound by a burr free steel wire with a diameter of 1-2mm (the outer diameter of the spring is 0
7-1mm smaller than the minimum inner diameter of the specified conduit)
Or use the bending auxiliary parts recommended by the manufacturer

4
3 lift the handles on both sides of the electrical casing bending tester, select the corresponding forming die (wheel) according to the samples with different diameters, insert the sample between the forming die and the bending roll (wheel), turn the clamping handle, and gently clamp it in the groove of the forming die with the clamping device

4
4 slowly press down the handles on both sides of the sample to make the total bending angle of the sample about 180 & deg;, So that when the profile roll is released, the sample is bent to 90 DEG; Angle, at 90 DEG; In this position, the angle shall be without damaging the specimen and bending auxiliary parts

4
5 after the test, observe whether the sample has cracks

4
6 if it is difficult to take out the sample, pull out the locating pin, turn the clamping device at a certain angle, and then take out the sample

4
7 after the test, wipe the electrical casing bending tester clean and store it in a dry place
