Germany dirk steinbauer workpiece clamping fixtures dirk steinbauer model dirk steinbauer price

dirk steinbauer workpiece clamping fixture is an electromagnetic chuck that secures the workpiece being machined by 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. Electromagnetic chucks vary due to differences in design methods or materials used, and they are continuously developing and improving. Initially, electromagnetic chucks were 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, and its application has significant limitations. 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.

dirk steinbauer workpiece clamping 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, paper industry, 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 lifting devices and vacuum nozzles. Generally, using vacuum suction cups to grab products is the most cost-effective method. There are various types 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 addition, 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 for manufacturing the suction cup. Typically, to avoid scratching the surface of the product, it is best to choose suction cups with bellows made of nitrile rubber or silicone rubber.

dirk steinbauer workpiece clamping 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 rotational 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.

dirk steinbauer workpiece clamping fixture maintenance

When using vacuum suction cups (without clamps), note that the manipulator's movement speed should not be too high; otherwise, a shear force will be generated on the suction cup, causing the product to easily fall off 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 can usually be installed to solve this problem. When the product's surface area is too small or the product is too heavy to use a vacuum suction cup, this problem can also be solved by using a clamp. If the product has strict appearance requirements, the clamped area must not be the outer surface. To solve this problem, 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 movement capability is limited and manual twisting or prying is required to demold the product or move it out of the molding area, a special cylinder capable of independent movement without relying on the manipulator operation can be added to improve this situation.
