What is The Precision of The High-Precision Shearing Machine to Cut The Sheet?

What does the hydraulic shearing machine symbolize in terms of the history of shearing machine revolution? The shearing machine clamp not only has good rigidity and stability, but also consists of the left and right column pressing panels, the working table and the inside of the oil tank. It is a hydraulic shear The whole main body of the trigger cutter, and its two oil cylinders lively on the supporting office connecting the left and right columns and the outer pressure plate.
Hydraulic shears are an important series among the types of shears that are flooded. Perhaps everyone does not understand the shears. So yesterday we talked about the important structure of the hydraulic shears. After its important structure, it is composed of one Let’s summarize how it works. In addition, the riveting structure of the triangular frame plate of the knife holder on the hydraulic shearing machine is equipped with rail plates, blades and backgauge installations. For the shearing machine, they are driven by large and small oil cylinders and return cylinders to achieve the shearing mission. .
What is the accuracy level of the high-precision shearing machine for cutting the sheet? The shearing accuracy of the shearing machine is in millimeters (mm), and the accuracy can reach 0.1mm per meter.

High-precision shearing machine

However, there are many factors that affect the precision of the shearing machine, such as the type of equipment used, the skill of the operator, the thickness of the material to be sheared, and so on.

National Precision Standard for Shearing Machine

Level 1 standard: Shear straightness ≤0.15mm/m Parallelism ≤0.10mm/m
Level 2 standard: straightness 0.15mm/m≤δ≥0.30mm/m, parallelism 0.10mm/m≤δ≥0.20mm/m

The type of shears affects the accuracy

Ordinary shearing machines are manual alignment. The shearing accuracy of Anhui Yongya can be controlled at 0.5mm/m. If the accuracy is higher, it is a CNC hydraulic shearing machine. The accuracy of the CNC shearing machine can be accurate. 0.1mm/m. Of course, the accuracy of manual line cutting depends on who is operating. The best accuracy of the backgauge is 1MM. If there is a requirement for accuracy above 0.1MM, it is better to use CNC.

Accuracy is affected by the thickness of the shear plate

The thickness of the shear plate affects the accuracy. It’s not easy to say. Why? The material of the plate (metal or non-metal), thickness (the effect of 1mm and 10mm is definitely different), width (also cut a 50mm wide strip, cross-cut It is different from the vertical shear width, so the accuracy is naturally different.) It is related, and it is not good to generalize. However, under normal circumstances, a thin plate of 1mm can be guaranteed, and the manual alignment accuracy of 0.1mm is almost impossible to achieve.
