Metal conduit bending test machine

Metal conduit bending test machine

1Product Overview：

Metal conduit bending test machineIt is a device for conducting flat bending tests on metal pipes. The product is widely used in the metal pipe industry, steel pipe manufacturing industry, and pipeline enterprises. Product quality and material performance testing institutions are used to test the bending performance of metal pipes. Using a high-quality motor to drive the turbine gearbox to drive the machine spindle, the bending roller is installed on the machine spindle. The pipe bending machine is started, and the bending roller rotates around the forming mold at a bending angle of 90 °. After the test, observe whether there are cracks in the sample. (Note: The production of forming wheels needs to be in a certain proportion with the conduit according to the national standard requirements)

5Product Features：

Metal conduit bending machineBy utilizing new technologies, we aim to achieve greater harmony and have specially installed protective limit devices. In the event of user error or abnormal digital control switches that fail to activate emergency braking, the limit devices can be activated and intelligently shut down, providing protection for the testing personnel and the machine itself. This device is an invention in itself. This device has reliable accuracy, easy use, reliable limit, and long service life. It is currently the most advanced bending testing machine.

VIOperation instructions：

1. Place the testing machine steadily and wipe the surface clean.

2. Before the experiment, insert the bending aid into the specimen. The bending aid can be a dense coil spring made of steel wire with a diameter of 1-2mm and no burrs (the outer diameter of the spring is 0.7-1mm smaller than the specified inner diameter of the conduit). Or use the bending auxiliary parts recommended by the manufacturer. The sample length is 30 times the nominal diameter,

3. Insert the sample into the groove between the forming mold and the bending roller (wheel).

4. Slowly press down the handle to bend the sample to a total angle of approximately 120 °, so that when the roller is released, the sample bends to a 90 ° angle. At this 90 ° angle, the sample and bending aids should not be damaged.

5. After the experiment, observe whether there are cracks in the sample, the weld should not crack, and the cross-section of the conduit should not deform excessively. After the experiment, the catheter should pass normally under its own weight using the corresponding gauge.

6. After the experiment is completed, wipe the testing machine clean and store it in a dry place.
