First of all, when using the hydraulic shear blade, it can not cut the laminated steel plate material. There is no need to trim the edge of the raw steel plate material. And there is no need to cut the narrow plate material that is not tight.

Not only that, the cutting edge of the shear blade should keep sharp. And if it becomes dull or cracked, we must replace or sharpen it in time. The gap between the cutters of the shearing machine is also very important.

And it is best to adjust it according to the thickness of the sheet to keep it within the allowable range. When the hydraulic shearing machine is working, the pressing device should firmly press the sheet. And it can not cut under the state of not being tight, so as to avoid accidents.

Due to the use of time and blunt mouth, the blade of the shearing machine becomes ground. And we should take out the shear blade before the blade is ground. Slitting machine blades are mainly used for sheet metal and strip slitting production lines. Using stable high-speed cutting tool steel SKD, SKH, tungsten steel, and other materials.

After a complete set of vacuum heat treatment processes, uniform hardness, precision processing. The slitting machine blade is the most important part of the slitting tool holder. And its processing precision is even more demanding. The round blade forms a round shape. Generally, the round blade is used in mechanical equipment, mainly for cutting, trimming, and other processing functions.

Round blades usually have a middle hole, the purpose is to make it fixed on the mechanical equipment. So as to achieve the cutting function. The improper selection of the slitting machine blade will easily shorten the service life of the slitting blade and fail to meet the requirements of the slitting index. The slitting material will produce burrs and produce a large amount of slitting powder.

The specific method is as follows. With a single stroke, when the upper tool post of the shearing machine descends to the bottom dead center. Quickly turn the ball valve to close the oil circuit and make the upper tool post stop at the bottom dead center.

When adjusting the gap, temporarily loosen the locking screw, then turn the handle to the required scale value. And then tighten the screw. Then continue to open and close the ball valve slightly to make the upper tool post rise step by step over the full stroke. At this time, the uniformity of the blade gap should measure step by step.

The adjustment of the shearing gap of the shear blade should be determined according to the thickness of the sheet, generally about 1/20 of the thickness of the sheet. After the adjustment of the cutting edge gap of the shear blade completed, try cutting one from the thin plate to avoid damage to the blade.

A hydraulic shear blade, also known as a hydraulic shear cutter or hydraulic shear knife, is a cutting tool used in hydraulic shearing machines. These machines are used in metal fabrication and manufacturing processes to cut various types of sheet metal, plates, and other materials. The hydraulic shear blade plays a crucial role in this cutting process.

Here are some key points about hydraulic shear blades:

Cutting Mechanism: Hydraulic shearing machines use hydraulic force to drive the shearing blade or knife through the material being cut. The hydraulic system provides the power needed to make clean and precise cuts in the metal.

Blade Design: Hydraulic shear blades come in various shapes and sizes, depending on the specific cutting requirements. The blades are typically made of high-quality tool steel or other durable materials to withstand the cutting forces and maintain sharpness.

Blade Edge: The blade edge of a hydraulic shear blade is carefully designed to ensure a clean and straight cut. It should be sharp and properly maintained to prevent material deformation, burrs, or rough edges on the cut pieces.

Blade Maintenance: Regular maintenance and sharpening of the hydraulic shear blade are essential to ensure optimal cutting performance and the longevity of the blade. Dull or damaged blades can lead to poor-quality cuts and increased wear on the machine.

Blade Replacement: Over time, hydraulic shear blades can wear out due to the abrasive nature of cutting materials like metal. When a blade becomes excessively worn or damaged, it needs to be replaced to maintain the efficiency and precision of the shearing machine.

Cutting Capacity: The size and thickness of the material that a hydraulic shear blade can cut depend on the capacity of the shearing machine. Hydraulic shears come in various sizes and configurations to handle a wide range of materials, from thin sheets to thick plates.

Safety: Operating hydraulic shearing machines requires careful attention to safety procedures, including the use of protective equipment and adherence to machine-specific safety guidelines. Hydraulic shears are powerful machines, and improper use can lead to accidents.

In summary, a hydraulic shear blade is a crucial component of hydraulic shearing machines used for cutting sheet metal and other materials. These blades are designed for precision cutting, and their maintenance and proper operation are essential for achieving high-quality and accurate cuts in various industrial applications.
