German henkel tools henkel models henkel prices

henkel tools are made of copper alloy. Due to the good thermal conductivity of copper 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 mixture containing 6.5-10%, undergoing 20 impacts without sparking or ignition.

henkel tool classification

1) Squeeze-exhaust suction cups rely on downward squeezing force to expel all air from the suction cup, creating a negative pressure state inside to hold the workpiece. They have advantages such as simple structure, light weight, and low cost. However, the suction force is not large, and they are mostly used for workpieces that are not too large in size, thin, and light. 2) Airflow negative pressure suction cups: An airflow control valve injects compressed air from an air pump through a nozzle, forming a high-speed jet that carries away the air in the suction cup cavity, creating negative pressure inside, allowing the suction cup to hold the object. If compressed air is available at the worksite, using this type of suction cup is convenient and low-cost. 3) Vacuum pump exhaust suction cups: Vacuum pump exhaust suction cups use an electromagnetic control valve to connect the vacuum pump to the suction cup. When the control valve evacuates air, the air in the suction cup cavity is removed, creating negative pressure to hold the object. Conversely, when the control valve connects the suction cup to the atmosphere, the suction cup loses suction and releases the workpiece. The suction force of vacuum pump suction cups mainly depends on the size of the suction area and the vacuum degree inside the suction cup (referring to the thinness of the air in the inner q cavity). This type of suction cup is reliable and has large suction force, but requires a vacuum pump and airflow control system, resulting in higher costs. 4) Mechanical clamping type: The structure of a straight-bar dual-cylinder translational gripper refers to fingers mounted on a straight bar with finger mounting seats. When pressurized gas enters the rod-side chambers of the single-acting dual cylinders, the two pistons move toward the center, clamping the workpiece; when no pressurized gas enters, springs push the two pistons outward, releasing the workpiece. To ensure synchronous movement of the two pistons, a flow divider valve is installed in the cylinder intake line. This type of end effector is used in loading and unloading assembly workstations.

henkel 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 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 flux lines are evenly distributed on the surface of the magnetic disk, electromagnetic suction force 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 magnetic force on the workpiece is limited to the contact surface between the workpiece and the chuck and cannot be changed arbitrarily. Therefore, there are disadvantages such as low positioning accuracy, insufficient clamping force, narrow scope of application, and low production efficiency during machining.

henkel tool usage

1) Explosion-proof tools provide safety assurance for personnel working in flammable, explosive, and corrosive environments, enhancing social safety and allowing workers to operate with greater peace of mind. After daily use, explosion-proof tools should undergo proper maintenance, which is crucial for their service life. Improper maintenance may prevent the tools from serving us for a long time. First, store the tools in a dry place to protect working parts from damage. In daily work, after continuous striking 20 times, treat the attachments on the tool surface, wipe clean before reuse, and avoid continuous use to prevent overheating due to prolonged friction, which could damage the tool product. 2) After use, wipe clean surface dirt and deposits, and store in a dry, safe place. 3) For striking tools, do not strike continuously; allow appropriate intervals after ten strikes, and promptly remove debris adhering to the product before continuing use. 4) Wrench-type products must not be used with excessive force, nor should sleeves or other metal bars be attached to extend the lever arm, nor should they be struck with a hammer (except for strike wrenches) to tighten fasteners. 5) Cutting-edge tools should be gently brought into contact with a grinding wheel in a water trough for sharpening; avoid excessive force and prolonged contact with the grinding wheel. 6) In actual operation with battering tools, clear site debris and corrosive oxides from the working surface to prevent third-party impacts. Based on the above performance and usage, aluminum bronze alloys are more suitable for normal pressure equipment and environments with less stringent explosion-proof requirements (such as gas stations and small oil depots), while beryllium copper alloy explosion-proof tools are suitable for applications such as refineries, gas transfer stations, gas production plants, and drilling teams. 7) Before using various products, remove surface oil stains and use according to the instructions for steel tools.
