• A sharp edge and a scooped back help you remove soft metal butts easily.
• If the cutting edge gets damaged, the blade can stick or break.
• Chips and cracks can mean the blade clearance is not correct.

Material dan Manufaktur

Heat treatment processes

Perlakuan panas makes shear blades strong and tough. You need strong blades for cutting steel and other metals. Special heat treatment and forging make the blade’s inside structure better. This helps the blade stay sharp and last longer. Methods like annealing, normalizing, and quenching change the blade’s inside. You get more strength, flexibility, and toughness. These things are important for good cuts and long blade life.

Toughness vs. hardness balance

You want a blade that is hard enough to cut steel. But it also needs to be tough so it does not break. Forging lines up the inside grain with the blade’s shape. This makes the blade stronger and helps it last longer. You get a blade that stays sharp and works well. Nanjing Metal Industrial uses these methods to make good shear blades.

Edge Profile and Blade Shape

The edge profile and blade shape change how well you cut billets. You need the right edge angle and small details for good cuts. Studies show that blade shape changes how well the blade works and how long it lasts. For example:

You get better cuts and longer blade life with the right edge profile.

Tip: Always match the blade shape and edge profile to your steel billet and cutting needs. This helps you get the best precision and quality in your metal manufacturing process.

Bar shear blades with special designs help you cut steel with high accuracy and quality. You get blades that last longer, cut better, and work well in metal manufacturing.

Distortion Control in Metal Shearing

Distortion can mess up your work when you shear metal. You want your cuts to be straight and smooth. You also want to stop problems like fishtailing and smearing. The right blade shape and sharpness help you control distortion. You can use special ways to cut metal for better results.

Blade Geometry Impact

V-block and rake profiles

You need to look at the shape of your blade. V-block profiles hold the billet steady when you cut. This keeps the billet from moving and helps you cut straight. Rake profiles change how the blade touches the metal. Low rake angles make cutting smoother. You use less force and get more accuracy. The right profile helps you stop bending and stretching the metal. You see fewer distortion problems with blades that have the best shape.

Stress distribution

Stress distribution is important when you shear metal. If you spread the force evenly, you get cleaner cuts. The blade shape controls how stress moves through the billet. V-blocks and low rake angles help spread the force. This lowers the chance of fishtailing and smearing. You get better results with the right cutting methods. You also keep your blade safe from damage.

Tip: Always check your blade shape before you start shearing. Good blade shape gives you better accuracy and less distortion.

Edge Sharpness and Maintenance

Burr reduction

Sharp blades really help when you shear metal. You get fewer burrs and smoother edges. Burrs are rough bits left after you cut. They can cause trouble in later steps. When your blade is sharp, you see less fishtailing and smearing. Here are some facts about sharp blades and good cuts:

• Less edge stretch means sharp blades make better cuts. This helps you stop fishtailing and smearing.
• The best edge keeps damage and changes inside the metal low. You get better results when you cut billets.
• Bad edge quality can cause cracks. For example, rocker panels made from DP980 had more cracks when the edge was not sharp.

You need to keep your blades sharp for the best results when you shear metal.

Alignment and clearance

Blade alignment and clearance are key for good cuts. If your blades are not lined up, you get uneven cuts. You also see more distortion. Clearance is the space between the blade and the billet. You need the right clearance for each way you cut metal. Too much clearance makes burrs. Too little clearance can hurt the blade. You should check alignment and clearance before you start shearing.

You can use good care steps to keep your blades sharp and lined up. Here is a table that shows what you should do:

You can follow these steps to keep your blades working well. You get better accuracy and less distortion when you shear metal. You also help your blades last longer.

Note: Good care helps you avoid stopping work and keeps your shearing process running well.

You control distortion in metal shearing by using the right blade shape, keeping blades sharp, and following good care steps. You get smooth cuts, better accuracy, and fewer problems like fishtailing and smearing. You also make your metal cutting better and your work easier.

Blade Material Selection for Precision

Picking the right blade material is very important. It helps you cut billets with accuracy. You need to know how alloys and hardness ratings change blade performance. This helps you choose blades that make clean cuts. Good blades last longer and help you work faster.

Alloy Choices

You have many choices for blade material. Each alloy has special benefits for cutting billets. The table below shows three steel alloys used in shear blades:

Toughness for solid stock

Blades need high toughness for cutting solid stock. S7 steel is very tough. This helps the blade avoid cracks and chips. A8 steel is also tough and works well for many cuts. Tough blades handle stress and impact better. You get more reliable cuts with tough blades.

Ketahanan aus

Wear resistance keeps blades sharp for longer. D2 steel has high wear resistance because of its carbon and vanadium. D2 is good for cutting rough materials. CPM steels are also great for wear resistance. They have a uniform structure inside. If you want blades that stay sharp, pick alloys with high wear resistance.

• Different alloys like A series, D series, and CPM steels change how long blades stay sharp.
• D series steels, like D2 and D7, work well in hard cutting jobs.
• CPM steels use a special process to make their structure even. This helps with toughness and wear resistance.

Hardness Ratings

HRC and durability

Hardness ratings use the Rockwell C (HRC) scale. They show how strong your blade is. Higher HRC means the blade is harder and keeps its edge longer. Hard blades are good for precise cuts. They resist wear and stay sharp for many uses. With the right hardness, you spend less time fixing blades. You get better and more steady results.

HRC ratings tell you how hard shear blades are. Hard blades last longer and cut better. High HRC means blades keep their sharpness and resist wear. This is important for good cutting over time.

You should match blade hardness to the steel you cut. For example, A8 steel with 55-60 HRC is good for punches and dies. D2 steel is best for blanking and trimming. S7 steel is great for jobs needing impact resistance.

If you want help picking blade material, you can ask Nanjing Metal Industrial. They know a lot about steel blade materials. They help you get the best results for billet cutting.

Tip: Always think about both toughness and hardness when picking blade material. This helps you get blades that last and cut well.

You get better cuts and longer blade life by picking the right steel alloy and hardness. This helps you work faster and get the accuracy you need for billet cutting.

Shear Blades for Different Applications

Cold Cropping vs. Hot Shearing

Speed and impact requirements

You must pick the best way to cut billets. Cold cropping uses strong blades and big machines. It cuts billets at room temperature. This method needs fast hits and lots of force. You get clean cuts if you line up the billet and blade well. Hot shearing is not the same. You heat the billet until it gets soft. The blade cuts with less force. The process goes faster. Hot shearing is good for big billets or hard metals.

Thermal fatigue resistance

Hot shearing makes blades face high heat many times. You need blades that can handle this heat. These blades keep their shape and stay sharp after many hot cycles. Special blade materials and coatings help them last longer. Cold cropping does not need as much heat resistance. But it does need blades that can take strong hits without breaking.

Process Workflow Comparison

You can see how cold cropping and hot shearing are different:

With cold cropping, you set up the billet and blade. You use a strong, quick hit to cut. This works best for metals that stay strong when cold. Hot shearing starts by heating the billet. The blade then slices through the soft metal. You use hot shearing for billets that are too thick or tough for cold cropping.

Suitable Materials Comparison

You must match your cutting way to the metal. Cold cropping works for metals that stay strong when cold. You use it for carbon steels, alloy steels, and non-ferrous metals. Hot shearing is better for billets that get soft when heated. You use it for high-alloy steels, big billets, and metals like aluminum. This helps you get good cuts and waste less material.
