Hydraulic Shear Machine Advantages - SHENCHONG

The hydraulic shear machine is a machine that uses a reasonable blade gap to apply a shearing force to metal sheets of various thicknesses by using a moving upper blade and a fixed lower blade to make the sheets break and separate according to the required size.

According to different working principles, they can be divided into hydraulic swing beam shearing machine and hydraulic guillotine shearing machine.

Hydraulic guillotine metal shear machines are often used in modern sheet metal processing production lines for ironworkers, because of its higher cutting accuracy, adjustable shear angle, longer blade life, longer oil cylinder life, and wider application range.

1. Higher cutting accuracy

The guillotine shear metal sheet cutting machine makes a vertical linear movement to achieve a smaller degree of distortion and a more accurate straightness of the sheared material. In addition, the guillotine hydraulic plate shearing machine is not easy to deform because the oil cylinder, the knife beam, and the blade are in the same straight line and move perpendicular to the lower blade.

In , Wuxi Shenchong successfully developed high-precision CNC hydraulic shear cutting machines and mass-produced them. The straightness of Shenchong hydraulic metal shear machine per meter is ±0.03MM, which can be used for laser tailor welding.

2. Adjustable shear angle

When cutting plates with a thickness of less than 20mm, the pendulum hydraulic punch and shear machine cannot adjust the cutting angle, so the cut material has twist-like distortion. The narrower the cut material, the greater the distortion.

The guillotine hydraulic shear machine can adjust the angle by adjusting the volume of the enclosed oil cavity of two oil cylinders in series:

– The shearing angle is enlarged and the shearing capacity is increased.

– The shearing angle is reduced, and the shearing speed is increased, saving electric energy and working time.

Wuxi Shenchong hydraulic shearing machine adopts the latest computer technology and has the characteristics of compact structure and complete functions. In addition to the controllable cutting angle, it can also control the backgauge stroke, blade clearance and cutting stroke.

3. Longer blade life

Steel Cutting Blade For Sale

For swing beam shear cutting machine, its top blade cannot be used for 4-sided cutting, because the motion line of the knife body of the hydraulic swing beam metal cutting machine is arc-shaped. So only the blade can be used for two-sided cutting.

But for guillotine shear metal cutting machine, it moves up and down in a straight line, and can use rectangular blades with four-sided cutting edges, so the serving life of the hydraulic punch and shear cutting machine’s blades on the guillotine shearing machine is twice that of the pendulum type.

4. Longer oil cylinder life

The built-in oil cylinder used in the pendulum hydraulic brake shear machine is difficult to lubricate and repair. However, the upper and lower chambers of the engineering oil cylinder used by the guillotine shears do not need additional lubrication, which greatly increases the service life.

The hydraulic oil cylinder of Wuxi Shenchong guillotine hydraulic shearing machine is made of 45# steel quenched and tempered, the inner hole is finely bored and extruded, and the inner surface has high strength.

The piston rod is also made of 45# steel quenched and tempered, and the surface is plated with nickel and phosphorus, which has self-lubricating function to increase wear resistance.

5. Wider application range of hydraulic shear machine

The guillotine metal shearing machine has a wider range of use, and can cut and process metal plates of different materials, such as carbon steel, stainless steel, and aluminum alloy, etc.

The company is the world’s best Hydraulic cable shear cutter machine supplier. We are your one-stop shop for all needs. Our staff are highly-specialized and will help you find the product you need.

At the same time, because its metal cutting angle is adjustable, effective cutting can be achieved by adjusting the cutting angle for plates of different thicknesses.

All in all, when the equipment procurement cost is not considered, the Shenchong hydraulic metal shearing machine is more recommended, which has higher cutting accuracy and longer service life (for blade and oil cylinder), can meet more requirements of different materials and different thicknesses.

The overall work efficiency is higher for the sheet cutting work, and the return on equipment investment will be higher too for ironworker. Of course, if your requirement of shearing accuracy is not high and the shearing thickness is low than 16mm, the pendulum shears are still a good choice in terms of cost performance.

Mechanical Versus Hydraulic, What's the best for Shearing Metal

One of the most common and essential tasks in the fabrication business is shearing metal. Everyone agrees on how important it is to be able to shear metal in a fabricating shop. What few can agree on, however, is whether a hydraulic method or mechanical method works better. If you’re going to spend the money on either a mechanical or hydraulic shear, you’ll want to know which one actually works better and does the best job.

While the debate is still very much heated, we can give you some insight into which method is superior to the other. Here’s an introduction to metal shearing with a look at the pros and cons of both types of shear. This information will put you in a better position to make a wise and informed decision when purchasing equipment for your shop.

What You Need to Know About Shearing Metal

When someone says that they’re shearing metal, they’re referring to a process in which a piece of a metal sheet is separated by making a straight cut. Metal shearing is a precise cutting process in which producing a straight line is critical.

In order to get that straight line, you're going to need the right equipment which brings us to the great debate on mechanical versus hydraulic shearing machines. Like most varieties of equipment, each one has their own set of pros and cons to recommend.

Pros and Cons of a Mechanical Shearing Machine

Aside from reliability and price, the number one concern you should have about any shearing machine, is accuracy. Mechanical shearing machines are operated manually while hydraulic shearing machines feature numerical controls.

It’s worth noting that mechanical shearing machines have more safety concerns when compared to hydraulic shearing machines. That said, a mechanical shear can cut remarkably fast, but it should not be operated continuously for long periods of time. The machine will need rest and you’ll have to take time to adjust the blade gap.

Mechanical shearing machines are shock-resistant, simple, easy to maintain, and environmentally friendly. Due to the fact that mechanical shearing machines don’t require any hydraulic oil, they produce no hydraulic waste. Unlike hydraulic shearing machines which require cooling, a mechanical shear doesn’t waste much energy.

Pros and Cons of a Hydraulic Shearing Machine

One thing that you should know about the difference between a hydraulic shearing machine and a mechanical shear is that a hydraulic shear has a hydraulic transmission while a mechanical shear has a mechanical transmission. What does that mean for you and your shop? The hydraulic transmission is generally perceived to be smoother in terms of operation and more reliable. That’s a pro for hydraulic shearing machines!

Another thing you should know about hydraulic shearing machines is that they’re slightly more accurate than their mechanical counterparts. Hydraulic shearing machines are also equipped with a feature to prevent them from being overloaded. That overload protection can save you a lot of money as the machine will stop on its own whenever there’s an obstruction or when it’s about to max out the PSI of the shear.

Finally, hydraulic shearing machines tend to be much less expensive than mechanical shearing machines which makes them quite popular in many fabricating shops.

The Big Conclusion

In conclusion, both hydraulic and mechanical shearing machines have qualities to recommend. When examining the pros and cons of each and evaluating them your decision will ultimately come down to which factors you value the most.

Do you want the speed of the mechanical shear? Or do you want the accuracy of a hydraulic shear? If your shop wants to maintain an environmentally friendly image you might be better off with a mechanical shear than a hydraulic one. It all depends on what you value the most and what you want to get out of the machine. If you want to move through material rapidly and don’t need to shear all day long, a mechanical shearing machine would be suitable for your needs.
