Explosion-proof flat nose pliers are made of two types of beryllium bronze and aluminum bronze alloys. Among them, the working surface of beryllium bronze material has a hardness above that and a tensile strength of /aluminum bronze
The working surface hardness of the material is above and the tensile strength and explosion-proof performance are in line with national standards.
Explosion-proof flat-nose pliers are special auxiliary explosion-proof tools for fitters during operation and maintenance in flammable and explosive places such as petroleum, petrochemical, natural gas and coal mines. They are used for operations in narrow working spaces and can cut small parts or metals. Silk etc.
Flat nose pliers are a hand tool used to clamp and fix workpieces or twist, bend and cut metal wires. The shape of the pliers is shaped, usually including the handle, pliers jaws and pliers mouth. It consists of two pliers bodies with symmetrical structural shapes that overlap at the jaws and are fixed by riveting.
The pliers can be flexibly opened and closed as the fulcrum, and its design incorporates the lever principle. Pliers were originally used only to hold objects, such as fire tongs for blacksmithing.
Pliers are generally made of carbon structural steel. They are first forged and rolled into the shape of a pliers blank, and then undergo metal cutting processes such as grinding and polishing, and finally are heat treated. The handle of the pliers is designed into straight handle, curved handle and bow handle according to the holding form. Pliers are often in contact with live conductors such as wires, so the 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,
the common ones include pointed nose, flat nose, flat nose, round nose, curved nose, etc., which can adapt to the needs of working on workpieces of different shapes. According to their main functions and usage properties, pliers can be divided into clamping and shearing types and clamping and shearing types.
Clamping pliers are mainly used to clamp various objects or bend them into various required shapes. The clamping surface on the inside of the pliers mouth is generally chiseled with horizontal oblique or mesh-shaped groove-shaped teeth to clamp objects stably and firmly and prevent the clamped objects from slipping or moving. Clamp-type pliers are generally compact, with slender jaws, and can be operated with one or two hands. Clamping pliers such as curved nose pliers, needle nose pliers and flat nose pliers can flexibly clamp objects in a narrow operating space. They can also bend metal sheets, thin wires, etc. into various required shapes during inspection and assembly. The pin-pull spring used in mechanical instruments is usually a specialized tool used in the telecommunications industry to assemble circuit boards with dense parts. The clamping pliers have duckbill-shaped jaws and no prismatic teeth on the clamping surface of the jaws. It is a tool used for repairing reeds in the textile industry. Clamping pliers specially used for folding and installing circlip washers are called retaining ring pliers. There are two types of retaining ring pliers for holes and retaining ring pliers for shafts. Clamping pliers specially used for pulling flat or round rod-shaped workpieces are called carp pliers. They can also replace wrenches to pinch smaller bolts or pipe fittings. There are two hinge holes at the jaws of the carp pliers to adjust the clamping fulcrum and clamping range. Clamping pliers mainly used to clamp production and domestic pipes are called pipe wrench. It consists of a movable jaw and a fixed jaw. The size of the clamping mouth can be adjusted according to the thickness of the pipe fitting. Its working method is similar to an adjustable wrench. Pipe wrenches have a large load-bearing capacity.
