Material Matters: Thickness, Type, and Consistency

Not all shearing machines are created equal.  The type of metal you&#;ll be working with is the most critical factor to consider. Different machines are designed to handle various material thicknesses, types, and consistencies. Here&#;s a breakdown:

• Thickness: This is the most straightforward aspect. Measure the maximum thickness you plan to shear regularly. Shearing machines are rated for a specific maximum capacity. Don&#;t be tempted to push the limits &#; it can damage the machine and compromise safety.

• Type: The type of metal matters. Softer metals like aluminum can be handled by electric or air-powered shears. For tougher metals or thicker cuts, you&#;ll need a hydraulic or mechanical shear.

• Consistency: Even within the same metal type, there can be variations. For example, sheet metal with punched holes or uneven surfaces may require a more powerful machine than flat sheet metal of the same thickness.

Cutting Capacity: How Much and How Long?

Beyond material, consider the volume and size of the metal sheets you&#;ll be cutting.

• Quantity: Think about your typical workload. If you&#;re shearing a high volume of metal pieces, a production-oriented shearing machine with a higher capacity might be ideal.

• Length: Measure the longest cuts you&#;ll need to make regularly. Shearing machines have a maximum cutting length limitation. Make sure the machine you choose can handle your longest cuts without requiring multiple passes.

Guillotine vs. Swing Beam: Understanding Machine Design

There are two main types of shearing machine designs: guillotine and swing beam.

• Guillotine shears: These work similarly to a paper trimmer. A fixed upper blade descends onto a fixed lower blade, making the cut. Guillotine shears are generally more affordable and well-suited for lower-volume metalworking.

• Swing beam shears: In these machines, the upper blade is mounted on a pivoting arm that swings down to meet the lower blade. Swing beam shears offer more throat depth (the distance between the machine frame and the blade) and can handle larger or wider materials. They are typically more expensive than guillotine shears.

Safety Features: Protecting Yourself is Paramount

Never underestimate the importance of safety.  Look for shearing machines with essential safety features like:

• Blade guards: These shields protect your hands from accidental contact with the blades.

• Emergency stop buttons: These allow you to immediately halt the shearing process in case of emergencies.

• Foot pedal operation (optional): Foot pedals free up your hands for better material handling and can improve safety.

• Two-hand controls (optional): These require the operator to use both hands to initiate a cut, minimizing the risk of accidental shearing.

Rake Angle: Finding the Right Balance Between Cut Quality and Power

The rake angle refers to the angle at which the upper shearing blade is tilted. This angle impacts the quality of the cut and the force required to make the shear.

• Lower rake angle: This produces a cleaner, straighter cut with less distortion. However, it requires a more powerful machine to overcome the increased resistance.
• Higher rake angle: This requires less force but can result in a less clean cut with more potential for material twisting or bending.

The ideal rake angle depends on your priorities. If a pristine cut finish is essential, a lower rake angle might be worth the trade-off for a more robust machine.

By considering these five key factors, you&#;ll be well on your way to selecting the perfect shearing machine for your metalworking needs. Remember, don&#;t hesitate to consult with a professional to discuss your specific requirements and get recommendations tailored to your workshop.

Especially for the shearing machine, for the required range of the material thickness of the sheared material, the size of the slitting machine, etc., after the model parameters of the machine are determined, you can contact the manufacturer to buy it.

The Suitable Machine is The Best

When buying a shearing machine, many users value a shearing machine with &#;good quality and multiple functions&#;. A good quality shearing machine is a necessary condition, but whether there are many functions depends entirely on their own needs. In theory, the simpler the performance, the better and more stable it is.

You Get What You Pay For, It is The Eternal Law of Business

Many users always want to spend the least amount of money to buy the best shearing machine, which is human nature. But you get what you pay for every penny. Not to mention the quality of the low-priced shears, the after-sales service is only 108,000 miles away. After contacting a number of companies that produce machines and obtaining the price, parameters, payment and delivery methods of the machines, the most important step is to choose the manufacturer to buy.

Generally, a trusted manufacturer is selected after removing the highest and lowest prices, so as to obtain better cost performance and at the same time ensure quality and after-sales service. Buying a good shearing machine equipment can save production costs. It is not only important to choose a good shearing machine, but also a good shearing machine manufacturer. Based on these, we have summarized ten manufacturers for your reference: https://www.vigert.com/top-10-shearing-machine-manufacturers/

Accessories Are Important

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

After-sales Service of Shearing Machine Manufacturers

No matter how high-quality shears are used for a long time or not used for a long time, it is inevitable that there will be no failures. At this time, the after-sales service experience of shearing machine manufacturers can be reflected. After all, if the equipment fails, no one wants to ask the manufacturer to come and repair it.

When choosing a shearing machine, it must be determined from meeting the demand, cost performance and after-sales service of the shearing machine manufacturer. Blind pursuit of low price, or function more often than not pay.

Types of Shearing Machine

Special Shearing Machine

Use with other equipment to complete special purposes:

• Shearing machine for cold bending forming line: such as special shearing machine configured on production lines such as automobile longitudinal beam cold bending line, carriage side baffle production line, color steel plate forming line, etc.;
• Shearing machine for steel structure production line: it is mostly used for angle steel and H-beam automatic production line to complete the shearing process;
• Plate opening and leveling line shearing machine: It is a high-speed plate shearing machine designed to meet the requirements of high-speed cutting of the production line for plate uncoiling and leveling. The thick plate line is mostly hydraulic high-speed shearing machine, and the thin plate line is more Equipped with pneumatic shearing machine; high-speed line is equipped with flying shearing machine, continuous production and high efficiency.

Swing Beam Shearing Machine

The upper and lower blades of the shearing machine are at an angle. Generally, the upper blade is inclined, and the inclination angle is generally 1° to 6°. The shearing force of the inclined blade shearing machine is smaller than that of the flat blade shearing machine, so the motor power and the weight of the whole machine are greatly reduced, and the practical application is the most.

Guillotine Shearing Machine

The shearing quality is good, the distortion is small, but the shearing force is large and the energy consumption is large. More mechanical transmission. The upper and lower cutting edges of the shearing machine are parallel to each other and are often used for the hot shearing of blooms and slabs in rolling mills.

Multipurpose Shearing Machine

• Combined punching and shearing machine: it can complete the shearing of the sheet and the profile, which is mostly used for the blanking process;
• Sheet metal bending and shearing machine: that is, two processes of cutting and bending can be completed on the same machine.

Shearing Machine Models

• Which of the shearing machine models are more commonly used?

Regarding the shearing machine models, some of the more commonly used ones are mainly Q11 series mechanical shearing machine, QC11 series hydraulic gate shearing machine, QC12 series hydraulic pendulum shearing machine and K series CNC shearing machine. It&#;s these four.

• How is the model of the shearing machine generally expressed? In the international model, what is the code name of the shearing machine?

The representation of the shearing machine model, generally, is 11X, of which the front 11 refers to the shearing thickness of the shearing machine, in millimeters. The following refers to the cutting width. For example, 20X means that the shearing thickness of the shearing machine is 20mm and the shearing width is mm.

The shearing machine, among the international models, belongs to the category of shearing units, so its code name is the capital letter Q.

If the thickness is less than 4mm, the mechanical shearing machine is generally selected. If the thickness is more than 4mm, the swing shear is generally selected if the thickness is less than 8mm, and the gate shear is generally selected if the thickness is higher than 8mm.

Shearing Tool Selection

The blade materials of the shearing machine are generally 9CrSI, 6CrW2Si, Cr12MoV, H13 and other materials.

• 9Crsi

It is a low-speed and low-alloy cutting tool steel. 9CrSi is brittle and hard, and is thermally sensitive to surface quenching and easy to crack. Steel for measuring and cutting tools 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 shearing machine blades with complex shapes, small deformation, high wear resistance and low-speed cutting. It is suitable for shearing of cooked copper. Mechanical properties: Hardness: HRC55~58 Heat treatment specification: quenching temperature 820~860&#;, tempering temperature 180~200&#;.

• 6CrW2Si

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 preserve relatively fine grains during quenching, and makes the steel in the tempered state. Get higher toughness. 6CrW2Si steel has higher quenching hardness and certain high temperature strength than 4CrW2Si steel and 5CrW2Si steel. It is usually used to manufacture shearing blades that are subjected to shock loads and require high wear resistance. It is suitable for shearing various ordinary steel plates and hard stainless steel plates. Mechanical properties: Hardness: HRC56~60 Heat treatment specification: quenching temperature 860~900&#;, tempering temperature 285~229&#;.

• Cr12MoV

It is a kind of die steel. The hardenability, hardness, strength and toughness after quenching and tempering are higher than CR12. The work 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-section, complex shape and heavy workload. The shear life is more 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~&#;, tempering temperature 200&#;~250&#;.

• H13 steel (4Cr5MoSiV1)

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

It is a representative steel grade that is widely used in hot work die steel. It is suitable for hot shearing of steel plates with temperature below 800°. Mechanical properties: Hardness: HR56~58 Heat treatment specification: quenching temperature ~&#;, tempering temperature 530~560&#;.

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