metabo fixtures Germany metabo models metabo prices

metabo fixtures are electromagnetic fixtures that secure workpieces by the suction force generated by the chuck body when the electromagnetic coil is energized. An electromagnetic chuck consists of an iron core, coil, faceplate, and bracket. The electromagnet, composed of the coil and iron core, is the main part of the electromagnetic chuck. Electromagnetic chucks vary due to differences in design methods or materials used, and they are continuously developing and improving. Electromagnetic chucks were initially used on grinding machines to replace clamping plates and bolts for securing workpieces to be ground. Such electromagnetic chucks are relatively simple and can only secure flat workpieces. This is the traditional electromagnetic chuck, which has significant limitations in its application. With industrial development, the demand for electromagnetic tools from enterprises has grown, and the requirements have become higher, prompting a series of improvements to electromagnetic chucks to meet production needs.

metabo fixture introduction

Vacuum suction cups are one of the actuators in vacuum equipment. The suction cup material is made of nitrile rubber, which has high tensile strength, and is therefore widely used in various vacuum holding devices, such as in construction, papermaking, printing, and glass industries, to perform tasks of holding and transporting thin and light items like glass and paper. Vacuum suction cups are also known as vacuum lifters and vacuum nozzles. Generally, using vacuum suction cups to grab products is the most cost-effective method. There is a wide variety of vacuum suction cups; rubber suction cups can operate at high temperatures, silicone rubber suction cups are very suitable for grabbing products with rough surfaces, and polyurethane suction cups are highly durable. In actual production, if oil resistance is required for the suction cup, materials such as polyurethane, nitrile rubber, or vinyl-containing polymers can be considered. Typically, to avoid scratching the product surface, it is best to choose suction cups with bellows made of nitrile rubber or silicone rubber.

metabo fixture structure

The mechanical gripper-type end effectors used in loading and unloading industrial robots are mostly two-finger claw types. According to the motion of the fingers, they can be divided into translational and rotary types. According to the mechanical clamping method, they can be divided into external clamping and internal expansion types. According to the mechanical structural characteristics, they can be classified as electric (electromagnetic), hydraulic, and pneumatic types, as well as their combinations. When the end effector clamps the workpiece, there should be certain force constraints and shape constraints to ensure that the clamped workpiece is completely released during movement, dwelling, and loading processes. In addition, it should ensure that the geometric deviation of the workpiece clamping posture reproduction is within the given tolerance zone.

metabo fixture maintenance

When using vacuum suction cups (without clamps), note that the manipulator's movement speed should not be too high; otherwise, shear forces will be generated on the suction cup, causing the product to drop easily during rapid twisting. In some cases, a clamp can be used to ensure safe transport of the product. Considering that the product may stick to the mold, an air clamp is usually installed to solve this problem. When the product surface area is too small or the product is too heavy for vacuum suction cups, clamps can also be used to solve this problem. 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 clamp or suction cup has securely grabbed the product, the sensor sends a signal to the manipulator to proceed to the next operation. In cases where the manipulator's motion capability is limited and manual twisting or prying is required to demold or remove the product from the forming area, a special cylinder capable of independent movement, not relying on manipulator operation, can be added to improve this situation.
