German ALBRECHT tools ALBRECHT models ALBRECHT prices

ALBRECHT 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 operational tools using low-power electric motors or electromagnets as the power source to drive the working head via a transmission mechanism. Power tools are divided into handheld and portable types; 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.

ALBRECHT tool applications and usage

Electric hydraulic oil pumps can serve as hydraulic pumps for various hydraulic devices. When equipped with other hydraulic tools, electric hydraulic oil pumps can perform lifting, pressing, pipe bending, bar bending, straightening, shearing, assembly, disassembly, and other tasks, reducing labor intensity and improving work efficiency. During use, open the air release nut, open the switch on the oil collection block, connect the power supply, and attach the quick connector to the quick coupling of the corresponding hydraulic device. Press the power switch; after the motor runs for 1-2 minutes, close the switch to the pressure-boosting state. At this point, the output hydraulic oil will perform various tasks, self-pressurizing as the load increases until 63MPA. After work is completed, open the switch to relieve pressure. Once the hydraulic oil has returned, remove the quick connector, tighten the air release nut, unplug the power cord, and close the switch.

ALBRECHT tool classification

Non-sparking tools are internationally known as "safety tools" and "non-sparking tools," and domestically in China as "explosion-proof tools." Explosion-proof tools produced, sold, and distributed in China are divided into two main categories based on material: 1. Aluminum-copper alloy (commonly known as aluminum bronze) explosion-proof tools, specifically made from high-purity electrolytic copper as the base with added aluminum, nickel, manganese, iron, and other metals to form a copper-based alloy. 2. Beryllium-copper alloy (commonly known as beryllium bronze) explosion-proof tools, specifically made from high-purity electrolytic copper as the base with added beryllium, nickel, and other metals to form a copper-based alloy. Both materials exhibit excellent thermal and electrical conductivity. After heat treatment, the hardness and wear resistance of aluminum bronze are nearly identical to those of beryllium bronze, both reaching above HRC30o. Beryllium bronze is non-magnetic and can be used in strong magnetic field environments. Explosion-proof tools can also be divided into two main categories based on manufacturing process: 1. Casting process: A traditional manufacturing technique that was the international standard for explosion-proof tool production in the 80s and continues to be used by most domestic manufacturers. Advantages of casting: Simple process, low manufacturing cost. Disadvantages: Lower product density, hardness, tensile strength, and torque; more pores and sand holes, resulting in shorter service life. 2. Forging process: The latest international manufacturing technique, using large presses or punch presses with high-heat-resistant forming molds for one-time forging. Advantages of forging: Significantly improves product density, hardness, tensile strength, and torque; basically eliminates pores and sand holes, extending mechanical performance and service life by approximately 1 times compared to traditional casting. Disadvantages: Higher investment in equipment and molds, leading to higher costs.

ALBRECHT tool operation

1) Single-phase power cords for portable electric machinery and handheld power tools must use three-core soft rubber cables; 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: No cracks or damage to the housing or handle; correct and secure connection of protective grounding or neutral wires; 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 of 500V. If the insulation resistance between live parts and the housing is less than 2M Ω, maintenance is required. 4) After repairing the electrical parts of power tools, insulation resistance measurement and dielectric withstand voltage tests must be performed. 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 operated 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 operated protective devices must not exceed 36V. 7) Operating switches for electric tools should be placed within easy reach of the operator. During breaks, after work, or in case of sudden power failure during operation, the power supply side switch should be turned off. 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 areas, 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 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.
