German AVN Group tools, AVN Group models, AVN Group prices

AVN Group tools are made of copper alloy. Due to the good thermal conductivity of copper and its nearly carbon-free nature, heat generated during friction or impact between the tool and an object is absorbed and conducted away in a short time. Another reason is that copper itself is relatively soft, providing good compliance during friction and impact, which makes it difficult to produce tiny metal particles. As a result, sparks are hardly visible, so 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 mixtures containing 6.5-10%, without sparking or ignition after 20 impacts.

AVN Group tool classification

1) Squeeze-exhaust suction cups expel all air from the cup by downward squeezing force, 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, so they are mostly used for workpieces that are not too large in size, thin, and light. 2) Airflow negative pressure suction cups use an airflow control valve to inject compressed air from an air pump through a nozzle, forming a high-speed jet that removes air from the suction cup cavity, creating negative pressure 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 connect the vacuum pump to the suction cup via an electromagnetic control valve. 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 degree of vacuum in the inner q cavity (referring to the thinness of the air). This type of suction cup is reliable and has strong suction, 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.

AVN Group 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 fixing larger workpieces; transverse arrangement 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, magnetic suction 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 on the workpiece is limited to the contact surface between the workpiece and the chuck and cannot be changed arbitrarily. Therefore, disadvantages during machining include low positioning accuracy, insufficient clamping force, narrow scope of application, and low production efficiency.

AVN Group tool types and features

Hydraulic tools include: hydraulic wrenches, electric pumps dedicated to hydraulic wrenches, hydraulic jacks, hydraulic bolt tensioners, hydraulic flange spreaders, hydraulic nut splitters, hydraulic pullers, etc. Hydraulic tools offer the advantages of high efficiency and convenience. 1) Generally use mineral oil as the working medium; relative moving surfaces can self-lubricate, resulting in long service life. 2) Light weight, compact size, small motion inertia, and fast response speed. 3) Various hydraulic transmission components can be conveniently and flexibly arranged as needed. 4) Automatic overload protection can be achieved. 5) Convenient operation and control, enabling wide-range stepless speed regulation (speed regulation range up to 2000:1). 6) Linear motion is easily achieved. 7) Machine automation is easily achieved; when electro-hydraulic combined control is adopted, not only a higher degree of automatic control process can be realized, but remote control is also possible.
