Germany osterland workpiece clamping fixtures osterland model osterland price

osterland workpiece clamping fixtures are one of the actuators for vacuum equipment. Generally, using vacuum suction cups to grip products is the most economical method. Vacuum suction cups come in various types; rubber suction cups can operate at high temperatures, silicone rubber suction cups are very suitable for gripping products with rough surfaces, and polyurethane suction cups are highly durable. In addition, in actual production, if oil resistance is required for the suction cups, materials such as polyurethane, nitrile rubber, or vinyl-containing polymers can be considered for manufacturing them. Typically, to avoid scratching the surface of the product, it is best to choose bellows-type suction cups made of nitrile rubber or silicone rubber. The suction cup material is made of nitrile rubber, which has high tensile strength, and is therefore widely used in various vacuum holding devices.

An electromagnetic chuck is an electromagnetic fixture that secures the workpiece being processed through the suction force generated by the chuck body when the electromagnetic coil is energized. The electromagnetic chuck consists of several parts, including an iron core, coil, faceplate, and bracket. The electromagnet, composed of the coil and iron core, is the main part of the electromagnetic chuck.

osterland workpiece clamping fixture manufacturing process

The electromagnetic chuck consists of a base housing, iron core, coil, faceplate, and junction box. Its manufacturing process is as follows: 1) Select suitable materials for welding or casting the base housing. 2) Install the iron core onto the base housing according to the different types of chucks. 3) Wind the coil with the corresponding number of turns and technical parameters, dry it, and then fit it onto the iron core. 4) Pour asphalt or other waterproof materials into the interior of the base housing. 5) Manufacture the faceplate and install it together with the base housing. Electromagnetic chucks use DC power supply and feature stability, strong suction force, and low residual magnetism. Electromagnetic chucks can be classified into standard suction chucks and high-power suction chucks. The suction force of standard suction chucks is 10-12 kg/cm², while that of high-power electromagnetic chucks is no less than 14 kg/cm². According to their applications, they can be divided into electromagnetic chucks for grinding machines, electromagnetic chucks for milling and planing machines, electromagnetic chucks for tool grinding machines, etc.

osterland workpiece clamping fixture maintenance

When using vacuum suction cups (without grippers), note that the manipulator's movement speed should not be too high; otherwise, shear forces will be generated on the suction cups, causing the product to drop easily during rapid twisting. In some cases, a gripper can be used to ensure safe transport of the product. Considering that the product may stick to the mold, an air gripper is usually installed to solve this problem. When the product's surface area is too small or the product is too heavy for vacuum suction cups, the issue can also be resolved by using grippers. If the product has strict appearance requirements, the clamped area must not be the outer surface. To address this, a sensor circuit can be installed. After confirming that the gripper or suction cup has securely held the product, the sensor sends a signal to the manipulator to proceed with the next operation. In cases where the manipulator's motion capability is limited and manual twisting or prying is required to demold the product or move it out of the forming area, a special cylinder capable of independent movement without relying on the manipulator can be added to improve the situation.
