Magnetic tools are tools that use electromagnetic technologies such as permanent magnets to assist the mechanical manufacturing process. They can be divided into magnetic fixtures, magnetic tools, magnetic molds, and magnetic auxiliary tools. The use of magnetic tools can greatly improve production efficiency and reduce the labor intensity of employees.
The earliest magnetic tool was the compass. Greek sailors used magnets to make compass, which could indicate the direction. An object floats in a bowl full of water, and the sailor places a needle-shaped magnet on the object, with one end of the magnet pointing north and the other pointing south. A compass tells sailors which way to go.
There are some magnetic tools used for car repairing and iron cutting tools for cleaning workshops, which are widely used in North America, Canada, Spain and other European countries, the United States of these developed countries. Ironically, China is the main producer of this tool, but there is no market in the country. This is far from our economy.
Some workpieces are inconvenient to be clamped due to their own structural characteristics during machining and assembly. Just place the U-shaped iron core vertically on the workbench for processing. At this time, we only need to insert a magnet on the positioning block of the fixture, and the workpiece can be firmly adsorbed on the workbench equipped with the positioning block. Positioning, which can greatly simplify the fixture structure and improve work efficiency. Some products need to weld some small parts to the workpiece. If they cannot be positioned accurately, not only the work is inconvenient, but also the requirements cannot be met.
In production, the magnetic properties of materials are often used to facilitate production, such as magnetic screwdrivers used in electronic product assembly. A large amount of finely crushed iron filings will be produced during machining, and these iron filings flow back into the recovery container with the cooling medium, often causing circuit blockage and inconvenient cleaning. A magnetic oil tank can be installed on the machine tool. During metal cutting, the cooling medium wrapped with iron chips flows into the oil tank from the oil drain tank of the workbench. When passing through the filter, the iron chips are blocked and accumulated on the side of the filter due to the action of the ring magnet, and the cooling The medium flows into the oil tank through the oil passage. When cleaning, the oil tank can be lifted very conveniently, and the chips can be poured out.
When bending and forming some workpieces with complex shapes, due to the deviation of the center of gravity, if the mold is too small, it may cause a cantilever and make the workpiece unstable, causing flipping and warping. For example, a positioning magnet can be added to the die to assist the positioning of the workpiece, which not only reduces the size of the mold, but also increases the reliability of positioning.
In stamping production, there is no gap when the steel plates used for processing are stacked together. Due to atmospheric pressure and other reasons, the plates stick together, making it extremely inconvenient to take out materials. The above-mentioned problem can be solved by installing a magnetic auxiliary table close to the punch press. The working principle is to fix a baffle on the workbench, install a magnet on one side of the baffle, and place the plate to be processed on the other side close to the baffle. , so that the plate vibrates up and down, and the uppermost plate leans against the baffle because the gravity is not enough to overcome the magnetic force, naturally forming a certain gap, and it is convenient to take out the material. The magnetic force can be adjusted by changing the thickness of the baffle.
Magnetic force is like an invisible hand that assists us to hold the workpiece. We have simplified the structure of various tools by cleverly using magnet technology, and also improved the process performance of the workpiece, making production easier. It can be seen that magnetic tools can help us Achieve unexpected results.
In some software applications, some modules are called magnetic tools. For example, in the deformation tool group in Poser4.0, there is a module called Magnetic Deformer (Magnet Deformer).
This type of magnetic deformation tool is one of the most commonly used and most effective deformation tools.
Composition of magnetic tools: A set of magnetic deformation tools consists of three components, they are: magnet (Mag), magnetic base (Mag Base) and action area (Mag Zone).
