Coiling Machines

In many ways, the coiling machine is very similar to the winding machine. A coiling machine or a winding machine is a machine that winds string, twine, cord, thread, yarn, rope, wire, ribbon, tape, etc. on a spool, bobbin, reel, The coiling machine must have a central roller, which is usually a bobbin, spool, reel, belt-winding shell, etc., on which material can be wound.

The central roller is divided into a round bar and a square bar. Round bars help increase speed, while square bars can supply greater torque power. The edge sensor is used to sense the fullness of the central roller. They are mounted on adjustable slides to accommodate many different widths, which will increase as the central roller fills. The sensitivity of the sensor depends on the required operating speed.
 
In the metal working industry, coiling is a broadly defined term that describes the rolling of metal materials into specific forms for further usages, such as spring coils. In addition, it can also be made into sheet metal rolls and put into inventory, and then spread out for further processing when required.

 

Spring coiling

In many industrial fields such as automobiles, motorcycles, sports and 3C consumables, spring coiling is an important part of almost every aspect. The spring coiling machine is the machinery that produces coil springs (also called helical springs). A coil spring is a mechanical part that can store and release energy. It can be used to absorb shocks or maintain support between the contact surfaces.
 
They are usually made of an elastic material formed into a helix shape and will return to their natural length when unloaded.
The accuracy of the spring will affect the accuracy and performance of the machinery it is installed on. The material of the coil spring (i.e. metal wire) is twisted when it is stretched or compressed. The spring characteristics depend on the shear modulus. There are many types of spring coiling machine due to the types of springs they are suitable for. Taiwan-made spring coiling machine are welcomed by users all over the world because of their high cost-effectiveness, and can greatly improve the productivity of users in different industrial fields.

 

Cut to length line

When the coiled material is to be used, a cut-to-length production line is usually used. In the sheet metal industry, fixed-length cutting is a method of making flat rectangular blanks from metal sheet coils. This method is also called CTL or blanking line. The cut-to-length production line will uncoil coiled materials, straighten or flatten them, and then cut them to the desired length. Some production lines also have devices that stack the cut materials together for easy storage or transportation.
 
Many suppliers use roller leveling technology to stretch and compress materials. This method can significantly improve flatness and material stability, thereby ensuring the accuracy of the final product.

 

Steel coil slitting

In the metal coiling and cutting production line field, there is another cutting type worth mentioning, namely the steel coil slitting line. It can keep the overall length of the unrolled sheet metal and cut it into narrower rolls. The mechanical operation of steel coil slitting is very similar to roll slitting. In the metal forming industry, automatic steel coil slitting production lines are widely used in various industries.
 
There are two types of slitting in Steel coil slitting, one is log slitting and the other is rewind slitting. In the process of log slitting, one or more slices can be taken out without uncoiling the entire metal sheet coil. In rewind slitting, the metal sheet coils needs to be uncoiled and passed through the cutter or laser on the machine to form a narrow roll.

 

Conclusion

During the metal forming procedure, the preliminary step is very important. It can determine the final quality of punching, pressing, forging or other metal forming process. The feeding device will give the required materials to the main forming machine to form metal products with specific shape. The coiling machine plays an important role in various production lines and manufacturing plants throughout the industry. It can be expected that with the technology progresses with the latest trends, these coiling process will eventually be enhanced to a very accurate level compared with the present.
