franken plastik fixture, German franken plastik model, franken plastik price

franken plastik fixture is an electromagnetic fixture that secures the workpiece by the suction force generated by the chuck body when the electromagnetic coil is energized. The 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. 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 plate-type 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.

franken plastik fixture working principle

The most widely used grippers are pneumatic grippers; they are essentially cylinders powered by compressed air. When air is supplied, the gripper jaws approach the object and firmly grasp it to perform other operations, and when the air direction is reversed, the gripper releases the object. Typical applications include changing the orientation of an object or moving the object in pick-and-place operations. When the gripper holds a workpiece, there should be certain force constraints and shape constraints to ensure that the clamped workpiece is fully released during movement, dwelling, and loading. In addition, it should ensure that the geometric deviation of the workpiece holding posture remains within the specified tolerance zone.

franken plastik fixture technology

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 type of chuck. 3) Wind the coil with the corresponding number of turns and technical parameters, dry it, and fit it onto the iron core. 4) Pour asphalt or other waterproofing materials into the interior of the base housing. 5) Manufacture the faceplate and install it together with the base housing. The electromagnetic chuck uses DC power supply and features stability, strong suction, and low residual magnetism. Electromagnetic chucks can be classified into standard suction chucks and high-power chucks. The suction force of standard suction chucks is 10-12 kg/cm², while high-power electromagnetic chucks are not less than 14 kg/cm². According to usage, they can be divided into electromagnetic chucks for grinding machines, milling and planing machines, and tool grinders.

franken plastik fixture applications

1) Consistently ensure workpiece machining accuracy: When using a fixture to clamp a workpiece, the positional accuracy of the workpiece relative to the tool and machine tool is guaranteed by the fixture, unaffected by the worker's skill level, ensuring consistent machining accuracy for a batch of workpieces. 2) Reduce auxiliary time and improve labor productivity: Using fixtures for workpiece clamping is convenient and fast; workpieces do not require marking and alignment, significantly reducing auxiliary time; clamping workpieces in fixtures increases their rigidity, allowing for increased cutting amounts; fixtures capable of clamping multiple workpieces or at multiple stations can be used, along with high-efficiency clamping mechanisms, further improving labor productivity. 3) Expand the scope of machine tool use and achieve multi-functionality: By attaching different types of fixtures according to the forming motion of the machining machine tool, the original process range of the machine tool can be expanded. For example, installing a boring jig on the carriage of a lathe or the table of a radial drilling machine allows for boring operations on box-type parts. 4) Ensure machining accuracy: Using fixtures for installation accurately determines the mutual position between the workpiece, machine tool, and cutter. The positional accuracy of the workpiece is guaranteed by the fixture, unaffected by the worker's skill level, resulting in high and stable machining accuracy. 5) Improve productivity and reduce costs: Clamping workpieces with fixtures allows for rapid positioning and clamping without alignment, significantly reducing auxiliary time; clamping workpieces in fixtures increases their rigidity, allowing for increased cutting amounts; fixtures for multiple workpieces and multiple stations can be used, along with high-efficiency clamping mechanisms, all of which help improve labor productivity. Additionally, using fixtures stabilizes product quality, reduces scrap rates, allows for the assignment of lower-skilled workers, and significantly lowers production costs. 6) Expand the process range of machine tools: Using special fixtures can change the original purpose of the machine tool and expand its scope of use, achieving multi-functionality. For example, after installing boring jig fixtures on lathes or radial drilling machines, boring operations can be performed on hole systems of box parts; special fixtures can also convert lathes into broaching machines, fully utilizing the capabilities of general-purpose machine tools. 7) Reduce worker labor intensity: Clamping workpieces with fixtures is convenient and fast; when using pneumatic, hydraulic, or other clamping devices, worker labor intensity can be reduced.
