Goudsmit Magnetic Fixtures Introduction

Magnetic fixtures are tools that utilize electromagnetic technologies, such as permanent magnets, to assist in mechanical manufacturing processes. They can be categorized into magnetic fixtures, magnetic tools, magnetic molds, and magnetic auxiliary devices. The use of magnetic tools can significantly improve production efficiency and reduce the labor intensity of employees.

The earliest magnetic tool was the compass. Greek sailors used lodestones to manufacture compasses, which could indicate direction. An object floated in a bowl filled with water; the sailor placed a needle-shaped lodestone on this object. One end of the lodestone pointed north, and the other pointed south. The compass indicated the course for the sailors.

Magnetic Fixture Processing Field

Some magnetic tools are used for automotive repair and for cleaning up iron cutting chips in workshops. They are widely used in developed countries such as those in North America, Canada, Spain, other European countries, and the United States. Ironically, China is the main producer of these tools, but there is no domestic market nationwide. This is far removed from our economic reality.

For some workpieces, clamping is inconvenient during machining and assembly due to their structural characteristics. Simply position the U-shaped iron core vertically on the worktable for processing. By embedding a magnet in the locating block of the fixture, the workpiece can be firmly attracted to the worktable equipped with the locating block, ensuring accurate positioning. This significantly simplifies the fixture structure and improves work efficiency. Some products require small parts to be welded onto the workpiece; if accurate positioning is not achieved, it not only makes the work difficult but also fails to meet requirements.

In production, the magnetic properties of materials are often utilized to facilitate operations, such as using magnetic screwdrivers during electronic product assembly. In mechanical machining, a large amount of fine iron chips is generated. These chips flow back into the recovery container with the cooling medium, often causing circuit blockages and creating inconvenience for cleaning. A magnetic oil trough can be installed on the machine tool. During metal cutting, the cooling medium containing iron chips flows from the worktable drain into the oil trough. As it passes through the filter screen, the iron chips are blocked and accumulate on one side of the screen due to the action of ring magnets, while the cooling medium flows into the oil tank through the oil channels. For cleaning, the oil trough can be conveniently lifted, and the chips can be dumped out.

GoudsmitMagnetic Molds

When bending and forming workpieces with complex shapes, an offset center of gravity may cause instability if the mold is too small, potentially leading to cantilevering, flipping, or warping. For example, adding a positioning magnet to the concave die can assist in workpiece positioning, reducing the mold volume while increasing positioning reliability.

GoudsmitMagnetic Auxiliary Devices

In stamping production, steel plates stacked for processing have no gaps between them. Due to atmospheric pressure and other factors, the sheets stick together, making material handling extremely inconvenient. Installing a magnetic auxiliary worktable closely against the press solves this problem. The working principle is as follows: a baffle is fixed on the worktable, with a magnet installed on one side. The sheets to be processed are placed tightly against the other side of the baffle. During operation, the vertical movement of the press slider and vibrations caused by the punching force cause the sheets to vibrate vertically. The top sheet, unable to overcome the magnetic force due to insufficient gravity, leans against the baffle, naturally forming a gap and facilitating material handling. The magnetic force can be adjusted by changing the thickness of the baffle.

Magnetic force acts like an invisible hand to help us hold workpieces. By cleverly utilizing magnet technology, we simplify the structure of various tools and improve the process performance of workpieces, making production easier. It is evident that magnetic tools can help us achieve unexpected results.

Goudsmit Other Applications of Magnetic Fixtures

In some software applications, certain modules are referred to as magnetic tools. For example, in the deformation tool group of Poser4.0, there is a module called the 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: Magnet (Mag), Mag Base (Mag Base), and Zone (Mag Zone).
