Construction universal clamp- X-pro clamp

Date: 28.07.2021 Viewed: times

X-pro clamp is a hand tool used to clamp and fix processed workpieces or to twist, bend, or cut metal wires. The shape of x-pro clamp is V-shaped and usually includes three parts: handle, jaw and mouth.

x-pro clamp are generally made of carbon structural steel, first forged and rolled into the shape of the pliers embryo, and then subjected to metal cutting processing such as milling and polishing, and finally heat treatment.


Basic meaning of x-pro clamp

The handles of the pliers are designed in three styles: straight handle, curved handle and bow handle according to the gripping style. The pliers are often in contact with live conductors such as wires, so their handles are generally covered with protective tubes made of insulating materials such as polyvinyl chloride to ensure the safety of the operator.

There are many types of pliers mouths, such as pointed mouth, flat mouth, flat mouth, round mouth, curved mouth and other styles, which can be adapted to the work needs of different shapes of workpieces. According to its main function and nature of use, x-pro clamp can be divided into clamping x-pro clamp, wire cutters, wire strippers, pipe pliers, etc.


Introduction of x-pro clamp

There are many types of x-pro clamp, and it has a wide range of uses. It is an indispensable hand tool for clamping and cutting workpieces in various industries such as assembly, repair and installation. But it has a common basic structure, that is, any hand-used x-pro clamp is composed of three parts: pliers head, pin and pliers handle. The basic principle of the x-pro clamp is to use two levers at a point in the middle and cross-connect them with a pin, so that the two ends can be relatively movable. As long as the tail end is operated by hand, the other end can pinch the object. . In order to reduce the force used by the user during operation, according to the principle of mechanical leverage, the pliers handle is usually made longer than the pliers head, so that a stronger clamping force can be obtained with a smaller force to meet the requirements of use. To


The three parts of x-pro clamp are as follows:

A pair of handles for holding. The pliers handle designed according to the ergonomic principle is convenient for safer and more comfortable holding. Connection shaft, this is the connection shaft point of the x-pro clamp. The connection point must move smoothly without any looseness, so that the x-pro clamp can be opened or closed easily with one hand. The pliers head strap holds the pliers mouth or cutting blade. The blades of the pliers are finely ground into a suitable shape. The two cutting edges (with springs) must be very sharp and close to each other accurately to make it easy to cut the wire.

This converts a small external force (such as the hand force applied on the pliers arm) into a larger power, so that the x-pro clamp can clamp or cut effectively. When the external force exerted on the pliers arm increases with the leverage ratio, the force of the pliers mouth produces an external force for clamping movement. If a large external force is to be generated, the distance from the center of the riveting position of the x-pro clamp to the handle must be as long as possible, and the distance from the clamping or cutting mouth to the riveting center must be as short as possible. However, many x-pro clamp will not greatly increase the hand strength, because they only make it easier to work in difficult-to-handle places, such as: electronic equipment assembly and electronic and precision engineering applications.

X-pro clamp are usually forged from alloyed and non-alloyed structural steel. For general x-pro clamp, they are made of high-quality carbon structural steel with 0.45% carbon content. x-pro clamp of high quality and for heavy duty operations are made of high carbon content and/or alloying elements such as chromium or vanadium.

The origin of x-pro clamp in Europe can be traced back to more than one thousand BC, when people just started to cast iron. During the casting process, x-pro clamp can be used to hold hot iron blocks. The shape of the forged x-pro clamp in the past has remained unchanged until now. The types of X-pro clamp have expanded with the development of handicraft, commerce and industrialization. There are 100 kinds of general-purpose pliers. Pliers for special applications are constantly increasing. Of course, these special x-pro clamp are not often available in the general-purpose range. The only company in Germany, the monthly output of x-pro clamp exceeds 1 million, about 50% of which are exported. Most of them are general-purpose x-pro clamp, such as cutting pliers, wire cutters and water pump pliers.

Regarding functions, the differences are as follows:

①The cutting pliers can be used for cutting or trimming (side cutting pliers, front cutting pliers, trimming pliers, etc.).

②Wire cutters can be used for cutting and clamping (wire cutters, crane nose pliers, electronic pliers, etc.).

Regarding the splicing structure, the differences are as follows:

① Butt splicing, such as woodworking pliers. Mounting on the top of the x-pro clamp does not require milling and riveting.

②Single shear splicing, such as wire cutters. Milling the joints, milling half the thickness, so that the two pieces of x-pro clamp are inserted into each other.

③ Sleeve type splicing, one handle is provided with a groove, and the other handle is passed through the groove and spliced at the joint. Casing spliced x-pro clamp—except for water pump pliers—because the use of harder alloy steel is more difficult to manufacture, so the manufacturing cost is higher. Therefore, compared with the first two splicing methods, it is relatively less important.


Different Types of x-pro clamp

X-pro clamp can be divided into: pinch type; shear type; pinch shear type. Divided by types and types, it can be divided into: hydraulic pliers; crimping pliers; hydraulic wire pliers; wire stripping pliers; rechargeable hydraulic cable pliers. According to the shape, it can be divided into: pointed mouth; flat mouth; round mouth; curved mouth; oblique mouth; needle mouth; top cutting; wire cutters; flower gill pliers, etc. According to the purpose, it can be divided into: DIY, industrial-grade pliers, special pliers, etc. According to the structure, there are two types: gill-piercing and gill-folding. The usual specifications are: 4.5” (mini pliers), 5”, 6”, 7”, 8”, 9.5” and so on.


The main categories are as follows:

Wire cutters

Wire cutters are a kind of clamp and cutting tool.

The wire cutter is composed of a pliers head and a pliers handle. The pliers head includes a jaw, a tooth, a knife, and a guillotine. The functions of each part of the x-pro clamp are: ①The tooth mouth can be used to tighten or loosen the nut; ②The knife edge can be used to cut the rubber or plastic insulation layer of the soft wire, and it can also be used to cut the wire and iron wire; ③The guillotine It can be used to cut hard metal wires such as wires and steel wires; ④The insulated plastic tube of x-pro clamp can withstand voltages above 500V, and it can cut wires with electricity. During use, avoid littering. So as not to damage the insulating plastic pipe. The wire cutters commonly used by electricians have a variety of specifications such as 150mm, 175mm, 200mm and 250mm.


Needle nose pliers

Needle-nose pliers are also called trimming pliers. They are mainly used to cut single-strand and multi-strand wires with smaller diameters, as well as to bend single-strand conductors and strip plastic insulation. They are also electricians (especially internal electricians) One of the commonly used tools. It is composed of a pointed tip, a knife edge and a pliers handle. The electrician's needle-nose pliers are covered with insulating sleeves with a rated voltage of 500V. Needle-nose pliers have sharp heads and are used in tight spaces. The operation method of using needle-nose pliers to bend the wire connector is: first fold the thread to the left, and then bend the screw to the right in a clockwise direction.


Wire stripper

Wire strippers are one of the tools commonly used by inside electricians, motor repairs, and instrument electricians. It is composed of a knife edge, a crimping mouth and a clamp handle. The clamp handle of the wire stripper is covered with an insulating sleeve with a rated working voltage of 500V.

Wire strippers are suitable for stripping plastic and rubber insulated wires and cable core wires.


Pipe Wrenches

Used to fasten or disassemble various pipes, pipeline accessories or round parts. Common tools for pipeline installation and repair. The inlay can be made by forging and casting. It is also made of aluminum alloy, which is characterized by light weight, light use, and not easy to rust.


Partial pliers

Partial-nose pliers are sometimes called diagonal pliers. When cutting wires, especially when cutting off the excess wire ends after the wire is wound on the welding point and the long leads after the printed circuit board is installed with the plug-in, the best effect is to use the tool of offset pliers. Partial-nose pliers are also commonly used to replace ordinary scissors to cut insulating sleeves and nylon cable ties. Partial-nose pliers with a length of 160mm and a plastic insulated handle are most commonly used.

Precautions of x-pro clamp

①Use the x-pro clamp to operate with your right hand. With the jaws facing inward, it is convenient to control the cutting position. Use your little finger to stretch the middle of the two pliers handles to resist the pliers handles, and open the pliers heads so that the pliers handles can be separated flexibly.

②The knife edge of x-pro clamp can be used to cut the rubber or plastic insulation layer of flexible wires.

③The blade of x-pro clamp can also be used to cut wires and iron wires. When cutting No. 8 galvanized iron wire, use a knife to cut back and forth around the surface a few times, and then only need to pull it lightly to break the wire.

④The guillotine can also be used to cut hard metal wires such as electric wires and steel wires.

⑤The insulated plastic tube of x-pro clamp can withstand voltage above 500V. With it, you can cut wires with electricity. Don't throw it around during use to avoid damaging the insulating plastic pipe.

⑥Do not use x-pro clamp as a hammer.

⑦Do not use x-pro clamp to cut double-stranded live wires, as they will short-circuit.

⑧When using x-pro clamp to wind the hoop to fix the cable, the x-pro clamp clamp the iron wire and wind it in a clockwise direction.

⑨It is mainly used for cutting single-strand and multi-strand wires with thinner wire diameter, as well as for bending single-strand conductor joints and stripping plastic insulation.
