German IBT tools IBT models IBT prices

IBT tools powered by electric motors or electromagnets, driving the working head through a transmission mechanism, are referred to as power tools. They are hand-held operating tools that use low-power electric motors or electromagnets as the power source to drive the working head via a transmission mechanism. Power tools are divided into two types: handheld and portable. Handheld power tools are more flexible, convenient, and widely used; many varieties have become essential tools for production and daily life. There are numerous power tool brands. Based on function and application, they are mainly classified into metal cutting power tools, grinding power tools, assembly power tools, and railway power tools. Common power tools include electric drills, electric grinders, electric wrenches and electric screwdrivers, electric hammers and impact drills, concrete vibrators, and electric planers.

IBT tool classification

1) Screwdriver: A tool used to turn screws to position them, typically featuring a thin wedge-shaped tip that inserts into the slot or recess of the screw head—also known as a "screwdriver bit". 2) Wrench: A manual tool with an open end or box end that uses 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, allowing the bolt or nut to be turned. When in use, applying external force to the handle in the direction of thread rotation turns 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 shapes, or break apart objects. Hammers come in various forms; a common form consists of a handle and a head. One side of the head is flat for striking, while the other is the hammer head. The hammer head can be shaped like a claw (for pulling nails) or wedge-shaped. There are also ball-peen hammer heads. 4) Test pen: Also called a voltage tester or simply "electric pen". It is an electrical tool used to test whether wires are live. The pen body contains a neon bulb; if the bulb lights up during testing, it indicates that the wire is live or is the live wire in 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 tail end with your hand; otherwise, because the live object, test pen, human body, and ground do not form a closed loop, the neon bulb will not light up, leading to a misjudgment that the live object is not electrified. 5) Tape measure: A commonly used measuring tool in daily life. Steel tape measures are frequently seen, often used in construction and decoration, and are essential household tools. Types include fiber tape measures, leather tape measures, and waist tape measures. Lu Ban rulers, Feng Shui rulers, and Wen Gong rulers also belong to the category of steel tape measures. 6) Utility knife: A type of knife with a sharp blade used for cutting wallpaper and similar materials, hence the name "wallpaper knife," also known as a "craft knife". It is frequently used in renovation, decoration, and signboard industries. 7) Electrician's knife: A cutting tool commonly used by electricians. A standard electrician's knife consists of a blade, cutting edge, handle, and sheath. When not in use, the blade retracts into the handle. The base of the blade is hinged to the handle, featuring scale lines and markings. The front end forms a screwdriver tip, both sides have file surfaces, the cutting edge has an inwardly curved blade section ending in a point, and the handle has a protection button to prevent the blade from snapping back. The electrician's knife integrates multiple functions, allowing various wire connection operations to be completed with just one tool, eliminating the need to carry other tools. It offers benefits such as simple structure, ease of use, and versatility. 8) Hacksaw: Includes hand saws (for household and woodworking use), pruning saws (for branch trimming), folding saws (for branch trimming), bow saws, veneer saws (for woodworking), rip saws (for woodworking), and crosscut saws (for 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 cutters: Wire cutters are clamping and cutting tools composed of a head and handles. The head includes jaws, teeth, cutting edges, and a cutter. The functions of the various parts 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 from soft wires, as well as to cut wires and iron wires; (3) The cutter can be used to cut harder metal wires such as electrical wires and steel wires; (4) The insulating plastic sleeves on the pliers withstand voltages above 500V, allowing for live wire cutting. 11) Needle-nose pliers: Also known as long-nose pliers, primarily used for cutting thin single-strand and multi-strand wires, bending loops for single-strand wire connectors, and stripping plastic insulation. They are also one of the common tools for electricians (especially interior 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 their pointed tips, 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 clockwise to the right against the screw. 12) Wire strippers: Wire strippers are one of the common tools for interior electricians, motor repair technicians, and instrument electricians. Their appearance is shown in the figure below. They consist of cutting edges, wire crimping slots, 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 from plastic and rubber insulated wires and cable cores. To use: place the wire end to be stripped into the blade slot of the head, squeeze the two handles together with your hand, then release, and the insulation will separate from the core wire.

IBT 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 configurations. Rectangular magnetic poles are arranged either longitudinally or transversely. Longitudinal arrangement of rectangular magnetic poles is suitable for securing larger workpieces, while transverse arrangement is suitable for securing smaller workpieces. Circular chucks are suitable for securing ring-shaped workpieces or workpieces with complex geometries. The main characteristics of standard electromagnetic chucks are: magnetic flux lines are evenly distributed across the chuck surface, magnetic attraction cannot be concentrated, and the magnetic force per unit area is relatively low; the direction of the magnetic force is perpendicular to the chuck surface and difficult to alter, generating only a single type of magnetic force for workpieces with the same contact area; the point of application of the magnetic force is limited to the contact surface between the workpiece and the chuck and cannot be freely adjusted. Consequently, machining operations suffer from disadvantages such as low positioning accuracy, insufficient clamping force, narrow scope of application, and low production efficiency.

IBT tool operation

1) The single-phase power cord for portable electric machinery and handheld power tools must use a three-core soft rubber cable, and the three-phase power cord must use a four-core rubber cable; when wiring, the cable sheath should pass into the junction box of the equipment and be secured. 2) Before using power tools, check the following items: no cracks or damage to the housing and handle; correct and secure connection of the protective grounding wire or neutral wire; intact cables or flexible cords; intact plugs; normal, flexible, and undamaged switches; intact electrical protection devices; intact mechanical guards; and flexible rotating parts. 3) The insulation resistance of power tools should be measured regularly using a megohmmeter with 500V. If the insulation resistance value between live parts and the housing is less than 2M Ω, maintenance must be performed. 4) After repairing the electrical parts of power tools, insulation resistance measurement and dielectric strength tests must be conducted. The test voltage is 380V, and the test duration is 1 minutes. 5) Electrical circuits connecting electric machinery and tools should have separate switches or sockets and be equipped with residual current operated protective devices (RCDs); metal housings must be grounded; it is strictly prohibited to connect multiple devices to a single switch. 6) The rated residual operating current of current-type RCDs must not exceed 30mA, and the operating time must not exceed 0.1 seconds; the rated residual operating voltage of voltage-type RCDs must not exceed 36V. 7) The operating switch of electric motor-driven tools should be placed within easy reach of the operator. During breaks, after work, or in case of sudden power outage during work, the power supply switch should be disconnected. 8) When using portable or mobile power tools, wear insulating gloves or stand on an insulating mat; when moving tools, do not lift them by the cord or rotating parts. 9) When using Class III insulated power tools in damp or acid-containing environments, or inside metal containers, reliable insulation measures must be taken, and a dedicated supervisor must be present. The power tool switch should be located within easy reach of the supervisor. 10) The magnetic disk surface of magnetic chuck drills should be flat, clean, and rust-free. When performing side drilling or overhead drilling, measures should be taken to prevent the drill body from falling in case of power loss. 11) When using an electric wrench, ensure the reaction torque support is firmly positioned and the nut is securely tightened before starting.
