How to Choose a Shearing Machine?

Nowadays, people are familiar with the shearing machine. The price is hundreds of thousands or millions. This is a great investment for the individual or business buyer. If you can't choose a good shearing machine, it will bring great losses to the buyer. It is a big burden, so buyers must fully understand and master the purchasing skills of shearing machines before buying shearing machines. Here are some tips for your reference.

Determine the specifications of the purchased machine according to your own demand parameters. At the same time, it is also necessary to consider the needs after the scale of the enterprise expands, and leave a certain margin to determine the parameters of the machine.

Especially for the shearing machine, for the required range of the thickness of the material to be sheared, the size of the cutting machine, etc., after determining the model parameters of the machine, you can contact the manufacturer to purchase.

When many users buy a shearing machine, they value the shearing machine with "good quality and many functions". A high-quality shearing machine is a necessary condition, but whether it has many functions depends entirely on your own needs. Theoretically speaking, the simpler the performance, the better and the more stable.

Many users always want to spend the least money to buy the best shearing machine, which is human nature. But you get every penny you pay for. Not to mention the quality of low-priced shears, the after-sales service is only a thousand miles away. After contacting a number of companies that produce machines and knowing the price, parameters, payment methods, and delivery methods of the machines, the most important step is to choose a manufacturer to buy from.

Generally, after removing the highest price and the lowest price, choose a reliable manufacturer to obtain better cost performance while ensuring quality and after-sales service. Purchasing good shearing machine equipment can save production costs.

When buying a shearing machine, pay attention to the accessories of the shearing machine to be purchased, such as the blade of the shearing machine, the pressing cylinder, and the feeding ball are all crucial accessories. The accessories of the shearing machine manufacturer are not the best, but they must be the most suitable.

Regardless of whether the high-quality shearing machine is used for a long time or not used for a long time, it is inevitable that it will fail. At this time, the after-sales service experience of the shearing machine manufacturer can be reflected. After all, if the equipment fails, no one wants to ask the manufacturer to come to repair it.

When choosing a shearing machine, it must be determined from the aspects of meeting the needs of the shearing machine manufacturer, cost performance, and after-sales service. Blindly pursuing low prices, or functions are often not as good as not paying.

Shearing machine blade materials generally include 9CrSI, 6CrW2Si, Cr12MoV, H13, and other materials.

It is a low-speed low alloy knife steel. 9CrSi is brittle and hard, sensitive to surface quenching heat, and easy to crack. Measuring cutting tool steel is a commonly used low-alloy tool steel with high hardenability and hardenability, as well as high tempering stability. It can be used to manufacture shear blades with complex shapes, small deformation, high wear resistance, and low-speed cutting. Suitable for shearing cooked copper. Mechanical properties: Hardness: HRC55~58 Heat treatment specification: Quenching temperature 820~860℃, tempering temperature 180~200℃.

It is a kind of alloy tool steel, which is formed by adding a certain amount of tungsten on the basis of chromium-silicon steel because tungsten helps to maintain relatively fine grains during quenching so that the steel is in a tempered state. Gain greater toughness. 6CrW2Si steel has higher quenching hardness and certain high-temperature strength than 4CrW2Si steel and 5CrW2Si steel. Usually used in the manufacture of shearing blades subject to shock loads and requiring high wear resistance. It is suitable for cutting all kinds of ordinary steel plates and hard stainless steel plates. Mechanical properties: Hardness: HRC56~60 Heat treatment specification: Quenching temperature 860~900℃, tempering temperature 285~229℃.

It is mold steel. The hardenability, hardness, strength, and toughness after quenching and tempering are all higher than CR12. Workpieces with a diameter of 300-400mm or less can be completely quenched, and the quenching deformation is small, but the high-temperature plasticity is poor. Cr12MoV is mostly used to manufacture shearing machine blades with large cross-sections, complex shapes, and heavy workloads. The sheer life is greater than 800,000 times. It is suitable for cutting high-hardness plates such as stainless steel plates and silicon steel sheets. Mechanical properties: Hardness: HRC56~60 Heat treatment specification: Quenching temperature 950~1000℃, tempering temperature 200℃~250℃.

It is an air-cooled quenching type hot work die steel. It has high toughness and resistance to cold and heat fatigue, and is not easy to produce thermal fatigue cracks; and has strong adhesion resistance and little interaction with molten metal, so it is widely used in hot heading, hot extrusion, and hot shearing. Trigger blade manufacturing. The performance and application are basically the same as 4Cr5MoSiV steel, but because of its high vanadium content, the medium temperature (600℃) performance is better than 4Cr5MoSiV steel.

It is a representative steel grade widely used in hot work die steel. It is suitable for hot shearing of steel plates below 800℃. Mechanical properties: Hardness: HR56~58 Heat treatment specification: Quenching temperature 1050~1080℃, tempering temperature 530~560℃.

Generally, CNC shearing machine manufacturers will use 9CrSi material steel to make shearing machine blades to save costs and reduce prices. Brand shearing machine manufacturers mostly use 6CrW2Si material tool steel, which can cut ordinary A3 plates and stainless steel metal plates, and is more wear-resistant. Cr12MoV and H13 are better tool steel materials, especially used for cutting stainless steel plates. Customers can choose the metal sheet they want to cut according to their needs.

The above introduces some factors that need to be considered when choosing a shearing machine. If you want to buy a shearing machine, please contact us.
