The spring 11 can balance the weights of the vertical rod 8 and the upper die 5. When weights are added, the weight of the weights will press on the plate to bend the plate, so as to obtain the force at which the plate begins to bend. During the experiment, the widths of the two plates are the same. The plate is placed between the lower die 6 and the upper die 5, which is convenient for the bending experiment. Compare the forces on the two plates, and then remove the two plates to observe the creases to determine the quality of the plates. The device does not need to be fully bent, only the experimental results are required. Pre-bend experiment on the plate to test whether the bending of the plate meets the predetermined requirements; Bend and compare two different plates, and select the better batch of products for processing.
