HELIOS PREISSER tools powered by electric motors or electromagnets, driving the working head through a transmission mechanism, are referred to as power tools. These are hand-held 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 categorized into handheld and portable types. Handheld power tools offer greater flexibility, convenience, and wider application; many varieties have become essential tools for production and daily life. With numerous power tool brands available, they are primarily classified according to function and purpose 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.

HELIOS PREISSER 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" or "turn-screw." 2) Wrench: A manual tool utilizing the lever principle to turn bolts, screws, nuts, and other threaded fasteners. Wrenches typically have jaws or sockets at one or both ends of the handle to apply external force, enabling the turning of bolts or nuts. When in use, external force is applied to the handle in 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 for driving nails, correcting alignment, or splitting objects. Hammers come in various forms; a common design consists of a handle and a head. One face of the head is flat for striking, while the other may be shaped like a claw or wedge for pulling nails, or rounded. 4) Test pen: Also known as a voltage tester or simply "electric pen." This 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 the wire is live or is the phase conductor. The tip and tail of the test pen are made of metal, while the shaft is made of insulating material. When using a test pen, one must touch the metal part at the tail end with their hand; otherwise, no circuit is formed between the live body, the test pen, the human body, and the earth, causing the neon bulb not to light up and leading to misjudgment that the live body is de-energized. 5) Tape measure: A common measuring tool in daily life. Steel tape measures are frequently seen, widely used in construction and decoration, and are a household essential. Types include fiber tape measures, leather tapes, and waist tapes. Luban 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. Standard electrician's knives consist of a blade, cutting edge, handle, and lanyard loop. 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 gouge ending in a point, and the handle has a safety button to prevent blade rebound. The blade integrates multiple functions, allowing various wire connection operations to be completed with just one electrician's knife, eliminating the need for other tools, offering benefits such as simple structure, ease of use, and versatility. 8) Hacksaw: Includes hand saws (for household and woodworking), 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) Combination pliers: Combination pliers are clamping and cutting tools consisting of a head and handles. The head includes jaws, serrated grips, cutting edges, and wire cutters. The functions of the various parts are: (1) The serrated grips can be used to tighten or loosen nuts; (2) The cutting edges can be used to strip rubber or plastic insulation from soft wires, as well as to cut wires and iron wires; (3) The wire cutters can be used to cut harder metal wires such as electrical wires and steel wires; (4) The insulating plastic sleeves on the pliers have a voltage resistance of 500V or higher, allowing 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 in single-strand wire joints, and stripping plastic insulation. They are also commonly used by electricians (especially indoor electricians). They consist of pointed tips, cutting edges, and handles. Electrician's needle-nose pliers have insulating sleeves rated for 500V on the handles. Due to their pointed heads, they are suitable for operations in narrow spaces. To bend wire joints with needle-nose pliers: first fold the wire end to the left, then bend it clockwise to the right against the screw. 12) Wire strippers: Wire strippers are commonly used by indoor electricians, motor repair technicians, and instrument electricians. Their appearance is shown below. They consist of cutting edges, wire crimping slots, and handles. The handles of wire strippers are fitted with insulating sleeves rated for 500V. Wire strippers are suitable for stripping insulation from plastic and rubber insulated wires and cable cores. To use: place the wire end to be stripped into the blade slot, squeeze the two handles together, then release; the insulation will separate from the core wire.

HELIOS PREISSER tool structural composition

The cross-sectional shape and distribution of the pole cores vary depending on the workpiece. Common structures of electromagnetic chucks include rectangular and circular types. Rectangular magnetic poles are arranged either longitudinally or transversely. Longitudinal arrangement of rectangular magnetic poles is suitable for securing larger workpieces; transverse arrangement is suitable for securing smaller workpieces. Circular chucks are suitable for securing ring-shaped workpieces or workpieces with complex shapes. The main characteristics of standard electromagnetic chucks are: magnetic flux lines are evenly distributed on the disk surface, magnetic 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 contact area; the point of action of the magnetic force is limited to the contact surface between the workpiece and the chuck and cannot be arbitrarily changed. Therefore, machining with these chucks suffers from disadvantages such as low positioning accuracy, insufficient clamping force, narrow scope of application, and low production efficiency.

HELIOS PREISSER tool operation

1) Single-phase power cords for portable electric machinery and handheld power tools must use three-core flexible rubber cables, and three-phase power cords must use four-core rubber cables; when wiring, the cable sheath must pass into the equipment's junction box and be secured. 2) Before using power tools, check the following items: housing and handles are free of cracks and damage; protective grounding or neutral connections are correct and secure; cables or flexible cords are intact; plugs are intact; switches operate normally, flexibly, and without damage; electrical protection devices are intact; mechanical guards are intact; and rotating parts move freely. 3) The insulation resistance of power tools should be measured regularly using a megohmmeter of 500V. If the insulation resistance 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; metal housings must be grounded; connecting multiple devices to a single switch is strictly prohibited. 6) The rated residual operating current of current-type residual current protective devices must not exceed 30mA, and the operating time must not exceed 0.1 seconds; the rated residual operating voltage of voltage-type residual current protective devices must not exceed 36V. 7) The operating switch for electric motor tools should be located 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 carry 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 assigned. The power tool switch should be located within easy reach of the supervisor. 10) The disk surface of magnetic chuck drills should be flat, clean, and rust-free. When performing side drilling or overhead drilling, measures must be taken to prevent the drill body from falling in case of power loss. 11) When using electric wrenches, ensure the reaction torque support is firmly positioned and the nut is securely tightened before starting.
