What are the requirements for material and cutting angle of NC plate shears?

Numerical control plate shears have been widely used in many factories. What are the characteristics of the material requirements for the blades of numerical control plate shears in actual production? Let's talk about:

The materials sheared by the plate shears are very different, and the temperature of the materials is also different.

This is the time to really test the red hardness and wear resistance of the plate shears.

The performance of small hydraulic pendulum plate shears. The temperature and thickness of high-temperature hot plate are a test of the blade of the plate shears.


The temperature here refers to the specific temperature of the material sheared by the hydraulic pendulum shear,

Difference in temperature tolerance of plate shears with different materials although many plate shears with different materials have strong high temperature resistance

However, the scope of their suffering is very limited. If the temperature of the processing material is higher than the limit that the blade of the plate shears can bear,

The blade will be damaged.


The thickness of the processed plate is also a great challenge to the blade of the plate shears,

And the thickness of the blade hardness requirements are also different.

If the hardness of the blade of the plate shears is too high, the blade is easy to break when cutting high-temperature thick plates.

Cutting angle of NC plate shears

No matter what kind of machining is used, there are three main angles: front angle, cut in angle and back angle.

Its functions are as follows: ① rake angle: it affects cutting force, cutting edge strength and chip flow characteristics; ② Cut in angle: control the direction of cutting force, effectively reduce chip thickness and protect the weakest part of the cutting edge; ③ Back angle: ensure that the tool will not rub against the workpiece when cutting.

Through the comprehensive optimization of these three angles of the tool, the cutting edge can be strengthened, and the workpiece material can flow out freely from the cutting area, so as to reduce the cutting force and prolong the tool life.

If the blade of the plate cutter is not used for a long time, * apply a layer of lubricant on the blade to prevent the blade from rusting.
