Scissors electric on metal. Manual scissors for metal. The indicator of the maximum thickness of the metal
Scissors for cutting metal are two knives fixed at a certain angle, which are equipped with handles. The larger the attachment angle (usually 7-12 degrees), the more solid material can cut these scissors. Electrical Options suitable for faster and more convenient work with metal.
Types of scissors for metal
Scissors are divided into manual and electrical models. Depending on the purpose and principle of cutting, hand-held metal scissors are:
With a length of 40 to 44 mm, it is distinguished by its working parts, the geometry of which is slightly rounded, which gives it the ability to easily remove curves, driving the sheet thanks to its micro-dirt. There are also rectangular straight drop scissors that allow you to cut in inaccessible places normal model, since the hand is no longer in scissors stretch.
Choosing electromechanical scissors
In monobloc shears, the Pelican Pass is known for long and continuous cuts due to its 75mm long blades. However, there are now articulated Pelican shears offering more power than the classic Pelican while being more compact.
- For straight cut- they are used if you need to make a straight cut.
- With curved blades - for cutting holes and parts.
- Finger - used for the same purposes, but have very thin blades.
- Chair - used for cutting thick sheets of paper.
- Lever scissors for metal - their base is mounted on a workbench.
Electrical options, in turn, are divided into the following types:
As for the cutting shears, the curved blades can penetrate the material and then make small diameter round cuttings. It should not be confused with shear shears, an important but less technical family that is used because its name suggests cutting a bit of everything at a construction site or workshop. This allows you to cut flat sheets without deforming the material, making curves more or less important. Its cutting method is different from the cutting method that goes through the shear.
Nibbler cuts the effect by cutting. Taken between them, the material is cut by pressure. As soon as it is necessary to cut a sheet thickness of more than 2 mm, a professional can turn to fixed scissors made of sheet metal. This applies in particular to the lever shift, which works according to the cutter principle and again has different sizes depending on the thickness of the sheet to be cut. The larger the lever, the lower the cutting force. The latter are fixed on a bench or on a closed foot. Capacities are typically 5mm for mild steel and up to 12mm for round steel.
- Sheet (cut) shears for metal are mainly used for cutting and cutting straight sheet metal with a thickness of 1.6 to 4.5 mm. Knives have square shape and four cutting edges.
- Metal nibblers work on the principle of a hole punch and are suitable for plumbing and roofing works. These scissors have small size, do not produce noise and vibration.
- Slotted shears for metal have a lower support blade and an upper movable pair cutting knives. Such scissors are always selected for the specific specifics of the work and the characteristics of the material being cut.
- Reinforcing shears - specially designed for cutting or biting metal rods different section.
In stores of the network Leroy Merlin» a wide range of metal shears is presented at various prices, and highly qualified employees of the company will always advise which metal shears to buy in a particular case. You can pick up the goods both independently and through delivery.
The safety system prevents the scissors from being accidentally closed, and the cutting line can benefit from lighting. There are also scissors that rest on a foldable base, allowing them to move from place to place and with a cutting width that can exceed one meter.
On the other hand, when it comes to machining on a larger scale, machines with large sizes enter workshops such as guillotine shears with manual or digital control, a cheaper alternative to laser cutting. We will not discuss them further on this issue.
Craftsmen who have been cutting sheet metal with hand shears know that this is a very laborious process, and it is also dangerous. And it’s not worth talking about cutting corrugated or profiled material. In this case, metal shears are ready to come to the rescue of professionals and amateurs. This tool is quite simple to use, for which you do not need much effort, since chopping or cutting is done automatically. When using such a unit, a fairly even cut line is obtained. Electric shears for metal are able to cut even three-millimeter material. It is worth considering what types they are.
In addition, cutting and cutting and ease of use, electric or battery-powered scissors can provide high efficiency cutting up to 4 or 5 mm, depending on the nature of the steel. Sometimes they have built-in cutting tools to control sheet thickness and offer different power and cutting speed to ensure cutting quality without distortion. This allows them to work faster, which is not negligible for those who use it constantly. Less complex than manual shears, electrical shear ranges are divided into three main types of shears, capable of cutting straight lines or curves, depending on the model.
All modern electric shears for metal can be divided into three types:
Slotted;
cutting;
For cutting sheet steel.
The generally accepted selection criteria are performance, power, equipment, reliability and functionality. Here you can give standard recommendations, which are based on the principles for choosing similar tools based on an electric motor. There is only a certain difference in terms of endurance, durability and reliability of the tool. In this sense, it would be best to focus on manufacturers who have already managed to prove themselves quite well: Bosch, Hitachi, Makita and ZUBR. It is worth saying that metal shears differ in compatibility, so some of them are suitable for some specific purposes, while not at all suitable for other tasks. This is what should be avoided.
The first alternative to hand scissors and high power cutting, goose shear knives are used for simple, long and silent cutting of sheet and of stainless steel. The so-called universal scissors do not cause deformation and are especially suitable for clean cutting on large flat surfaces with large radii. Whether producing a single regular and continuous chip or two chips, they sometimes integrate a chip cutter so as not to interfere with work.
The third type of powered shear, nipplers are especially suitable for trapezoidal, corrugated, profiles and other flat sheet metal, for which they provide excellent maneuverability and excellent strength crooked. In general, the compactness and ergonomics of a power tool are necessary to ensure its maneuverability and ease of tracking or calibration. It can even be used with one hand. The latter has just been developed in such a way that it can also be used with one hand.
In general, the choice of one type or another depends entirely on the tasks that you face.
