German AFFUTAGE tools AFFUTAGE models AFFUTAGE prices

AFFUTAGE tools are made of copper alloy. Due to copper's good thermal conductivity and its characteristic of being almost carbon-free, the heat generated in a short time when the tool rubs against or impacts an object is absorbed and conducted. Another reason is that copper itself is relatively soft, providing good compliance during friction and impact, making it difficult to produce tiny metal particles, so we hardly see any sparks. Therefore, explosion-proof tools are also called non-sparking tools. The materials for explosion-proof tools are beryllium bronze and aluminum bronze. Beryllium bronze alloys and aluminum bronze alloys do not spark upon impact or friction, making them very suitable for manufacturing safety tools used in explosive, flammable, strong magnetic, and corrosive environments. BeA-20C alloy withstands an impact energy of 561IJ in hydrogen containing 30% or in methane-air-oxygen containing 6.5-10%, impacting 20 times, without sparking or ignition.

AFFUTAGE tool classification

1) Screwdriver: A tool used to turn screws to force them into position, usually with a thin wedge-shaped head that can be inserted into the slot or recess of the screw head—also known as a "screwdriver". 2) Wrench: A hand tool with an open end or socket that utilizes the lever principle to turn bolts, screws, nuts, and other threaded fasteners. Wrenches usually have jaws at one or both ends of the handle to apply external force to the handle, allowing the bolt or nut to be turned. When in use, apply external force to the handle along the direction of thread rotation to turn the bolt or nut. 3) Hammer: A tool used to strike objects to move or deform them. It is most commonly used to drive nails, correct, or break apart objects. Hammers come in various forms; the common form consists of a handle and a head. One side of the head is flat for striking, while the other side is the hammer head. The shape of the hammer head can be like a claw, which functions to pull out nails, or it can be wedge-shaped. There are also round-headed hammer heads. 4) Test pen: Also called a voltage tester, abbreviated as "electric pen". It is an electrical tool used to test whether wires are live. There is a neon bulb in the pen body; if the neon bulb lights up during testing, it indicates that the wire is live or is the live wire of a circuit. The tip and tail of the test pen are made of metal, while the pen shaft is made of insulating material. When using a test pen, you must touch the metal part at the end of the test pen with your hand; otherwise, because the charged object, test pen, human body, and earth do not form a loop, the neon bulb in the test pen will not light up, causing a misjudgment that the charged object is not live. 5) Tape measure: A tape measure is a commonly used measuring tool in daily life. What people often see is the steel tape measure, which is commonly used in construction and decoration and is also one of the essential tools for households. It is divided into fiber tape measures, leather tapes, waist tapes, etc. Lu Ban rulers, Feng Shui rulers, and Wen Gong rulers also belong to steel tape measures. 6) Utility knife: A type of knife with a sharp blade, used to cut wallpaper and similar items, hence the name "wallpaper knife," also known as a "craft knife." It is frequently used in renovation, decoration, and billboard industries. 7) Electrician's knife: An electrician's knife is a cutting tool commonly used by electricians. Ordinary electrician's knives consist of a blade, cutting edge, handle, and blade lock. When not in use, retract the blade into the handle. The root of the blade is hinged to the handle, with scale lines and markings on it; the front end forms a screwdriver tip, both sides are processed with file surfaces, the cutting edge has a section of inwardly curved blade mouth, the end of the curved blade mouth forms a pointed tip, and the handle is equipped with a protection button to prevent the blade from bouncing back. The blade of the electrician's knife integrates multiple functions; when used, only one electrician's knife is needed to complete various operations for connecting wires, without carrying other tools, offering benefits such as simple structure, ease of use, and diverse functions. 8) Hacksaw: Includes hand saws (for household use, woodworking), pruning saws (for branch trimming), folding saws (for branch trimming), hand bow saws, edging saws (woodworking), rip saws (woodworking), and crosscut saws (woodworking). 9) Spirit level: A spirit level contains a bubble vial and can be used to inspect, measure, and debug whether equipment is installed horizontally. 10) Wire pliers: Wire pliers are a clamping and cutting tool, consisting of a head and handles. The head includes jaws, teeth, cutting edges, and shearing edges. The functions of the various parts of the pliers are: (1)) The teeth can be used to tighten or loosen nuts; (2)) The cutting edges can be used to strip the rubber or plastic insulation of soft wires, and can also be used to cut wires and iron wires; (3)) The shearing edges can be used to cut harder metal wires such as wires and steel wires; (4)) The insulating plastic tubes of the pliers have a voltage resistance of 500V or more, allowing live wire cutting. 11) Needle-nose pliers: Also called long-nose pliers, mainly used to cut thin single-strand and multi-strand wires, as well as to bend loops for single-strand wire connectors and strip plastic insulation. They are also one of the commonly used tools for electricians (especially internal wiring electricians). They consist of a pointed tip, cutting edges, and handles. The handles of electrician's needle-nose pliers are covered with insulating sleeves rated for 500V. Due to the pointed head, needle-nose pliers are suitable for operations in narrow spaces. The method for bending wire connectors with needle-nose pliers is: first fold the wire end to the left, then bend it to the right in a clockwise direction close to the screw. 12) Wire strippers: Wire strippers are one of the commonly used tools for internal wiring electricians, motor repair, and instrument electricians. Their appearance is shown in the figure below. They consist of cutting edges, crimping mouths, and handles. The handles of wire strippers are covered with insulating sleeves rated for a working voltage of 500V. Wire strippers are suitable for stripping the insulation of plastic and rubber insulated wires and cable cores. The method of use is: place the wire end to be stripped in the blade opening of the plier head, squeeze the two handles together with your hand, and then release; the insulation will separate from the core wire.

AFFUTAGE tool structural composition

The cross-sectional shape and distribution of the pole cores vary depending on the workpiece. Common structural types of electromagnetic chucks include rectangular and circular shapes. Rectangular magnetic poles are further divided into longitudinal and horizontal arrangements. Longitudinal arrangement of rectangular magnetic poles is suitable for fixing larger workpieces; horizontal arrangement of rectangular magnetic poles is suitable for fixing smaller workpieces. Circular chucks are suitable for fixing ring-shaped workpieces or workpieces with complex shapes. The main characteristics of ordinary electromagnetic chucks are: magnetic lines of force are evenly distributed on the surface of the magnetic disk, electromagnetic attraction cannot be concentrated, and the magnetic force per unit area is relatively small; the direction of magnetic force is perpendicular to the chuck surface and difficult to change, producing only one type of magnetic force for workpieces of the same suction area; the point of action of the magnetic force on the workpiece is limited to the contact surface between the workpiece and the chuck and cannot be changed arbitrarily. Therefore, during machining, there are disadvantages such as low positioning accuracy, insufficient clamping force, narrow scope of application, and low production efficiency.

AFFUTAGE tool usage

1) Before use, carefully inspect it to ensure there is no damage to the appearance, the switch operates flexibly without sticking, and the power cord and housing of the power tool are intact. Use a 500V megohmmeter to measure the insulation resistance between the winding and the housing, which must not be less than O.5 megohms; see the attached table for insulation resistance values. 2) Handheld power tools with metal housings must have a reliable protective grounding wire. The power cord is a multi-core soft rubber-sheathed cable, and its grounding protection wire must be securely connected at both ends. 3) Handheld power tools should be used by dedicated personnel with certain professional knowledge. Strictly adhere to relevant safety operating procedures during use. 4) Before use, check whether the related electrical protection devices and mechanical protection devices are intact and functioning normally. Also, pay attention to whether the rotating parts rotate flexibly without sticking. 5) When using Class I handheld power tools, users must wear prescribed protective equipment and set up qualified protective gear. Take corresponding anti-electric shock safety measures as required, such as installing residual current devices in the power circuit, or having the user wear insulating gloves, insulating shoes, or stand on an insulating mat. When using Class II handheld power tools in damp and narrow places, install a residual current switch with a working current of less than 1.5mA and an operating time of less than or equal to 0.1 seconds. The residual current switch should be placed inside the container and supervised by a dedicated person. 6) Occupational hazards of using handheld power tools. Arm vibration disease caused by long-term hand-transmitted vibration operations was listed as one of China's statutory occupational diseases as early as 1957, also known as local vibration disease, typically manifested as episodic white finger.
