Effectively picking out a good quality, high-performance foot pedal shearing machine, there are many things that we need to pay attention to. If you can't understand the relevant purchasing knowledge well, it will have a very big impact on the actual operation in the future.
In the actual selection process, for the bottom end of the stroke, in addition to the need to control the degree of the mold angle to be 86 ~ 90 °, in the middle of the concave and convex mold, it is necessary to have a gap slightly larger than the material thickness. There is one of them. In this way, it is possible to effectively reduce the damage of the rebound stress caused by the middle of the bending radius.
The accuracy requirement of the curve is an optional factor that we need to carefully consider. Because the accuracy of the curve is required or not, it is a good decision whether you need a pedal shearing machine for the corresponding use, or a manual folding machine to perform the corresponding operation.
In the actual use process, the repeatability of the slider in the pedal shearing machine is within the range of ±0.0004 inches. Moreover, for those angles that are precisely formed, it is necessary to use such precision and a good mold to perform the corresponding operations. However, for those manual folding machines, the repeatability of the slider is generally within ±0.002 inches. Moreover, under the condition of using a suitable mold, there will be a deviation of ±2~3°.
