Crane Rectangular Electromagnet

1. The principle of electromagnetic chuck

Electromagnetic chuck is a kind of electromagnetic principle,It is a machine tool accessory product produced by energizing the inner coil to generate magnetic force, passing through the magnetic conductive panel, and tightly attracting the workpiece in contact with the surface of the panel.

The electromagnetic chuck adopts DC power supply, which has the characteristics of stability, strong suction and small remanence.

The performance of a rectangular electromagnet is mainly determined by its coil parameters and core material. When selecting and designing a rectangular electromagnet, it is necessary to consider its current, voltage, power and other parameters, as well as its magnetic field strength, magnetic flux and other magnetic performance indicators.

2. application：

Our magnet is capable of lifting various types of materials with ease, from steel sheets and iron blocks to scrap iron, metal waste, and even cars. It has a high magnetic force that can lift up to thousands of pounds of material, making it ideal for use in various industries, including construction, recycling, automotive, and mining.

The main applications are: workpiece fixation of iron workpieces such as grinders, FYMC series electromagnetic sharpeners, gantry milling machines, gantry planers and other iron workpieces.

3. Component:

The electromagnetic sucker is composed of bottom shell, iron core, coil, panel and junction box. The production process is as follows:

(1) Select the appropriate material for welding or casting the bottom shell.

(2) Install the iron core on the bottom shell according to the different types of suction cups.

(3) Wind the coil with the corresponding number of turns and technical parameters, and put it on the iron core after drying.

(4) Pouring asphalt or other waterproof materials inside the bottom shell.

(5) Make the panel and install it with the bottom shell part.

4. Classification

Electromagnetic suction cups can be divided into ordinary suction cups and strong suction cups according to different classifications.

The suction force of ordinary suction cups is 10-12 kg per square centimeter, and the strong electromagnetic suction cup is not less than 14 kg per square centimeter.

According to the purpose, it can be divided into electromagnetic chuck for grinding machine, electromagnetic chuck for milling machine and planer, electromagnetic chuck for sharpening machine, etc.

Our Crane Rectangular Electromagnet is fully customizable to meet the specific needs of our customers. For example: modify its size, shape, and pull force to match the requirements of different businesses. Whether you need a smaller, more compact magnet or a larger electromagnet with a higher pulling capacity, we can design it to meet your needs.

5. Suction cup

The electric-controlled strong suction cup has super strong holding force, the maximum can reach 16kg/cm², the magnetic force distribution is uniform and adjustable, and can be applied to various strong machining, roughing and finishing; ordinary strong suction cups have weak suction and uneven distribution, Unable to withstand the demands of heavy machining operations.

6. Work efficiency

Ordinary strong suction cups require a lot of workpiece adjustment time, which can account for 40%-50% of the entire processing process, and the clamping positioning is prone to obvious errors, high rejection rate and very low efficiency; electronically controlled strong suction cups have automatic auxiliary positioning Function, simply press a button, the workpiece can be clamped or released in 0.3 seconds, which can greatly improve production efficiency.

7.Instructions for use of rectangular electromagnetic chuck

There are hoisting screw holes on both sides of the rectangular electromagnetic chuck, which can be hoisted by screwing in T-shaped screws during installation, fixed on the workbench with T-shaped blocks and screws, connected to the DC power supply and ground wire on the machine tool, and then put the suction cup on the plane Finish grinding once to ensure the parallelism of the upper plane to the bottom plane.

When absorbing the workpiece, as long as two adjacent magnetic poles are overlapped, sufficient positioning suction force can be obtained, and the grinding process can be carried out.

Through the button of the machine tool, the magnetization and demagnetization of the workpiece can be realized.
