How To Maintain The Uncoiler

Uncoiler, also known as decoiler, material rack, loading rack, unwinder machine, etc., is an indispensable unwinding device for metal coil to be stamped processing. Like the feeder, it is also a product that must be used on the factory workshop. It is suitable for the continuous stamping processing industry of various auto parts, hardware and electronic parts. We know a lot about several decoilers, and different uncoiler machines have different characteristics.

The decoiler/uncoiler plays a vital role in the cutting production line, pressing production line and various metal production lines. In order to allow it to be used for a longer period of time, we need to pay more attention to daily maintenance. Here are some useful tips.

1. Grease the decoiler/uncoiler mandrel regularly.

2. It is best to expand the coil within the acceptable parameters.

3. Check whether the core rod of the decoiler/uncoiler is stuck or abnormal before starting up.

4. Operate the uncoiler correctly according to the instructions and safety regulations.

5. When abnormal noise is heard, stop the uncoiler immediately.

6. In the metal production line, every operator in charge of different machines must cooperate closely.

Advantages of decoiler:

The decoiler is suitable for conveying various coil materials. Thin thin metal and non-metal materials can be equipped with motor power and feeding device. The brake device is adjustable and the main shaft is reinforced, which makes the rolling of the material roll more stable and increases its carrying capacity. It can automatically produce indispensable parts with the punching machine, saving manpower, material resources, and reducing costs. The effect is very good.

Uncoiler machine can save feeding time and improve production efficiency. It can be used with the calibration machine. It can be equipped with a motor and electrical control instead of a power frame.

A Guide To Uncoilers

Capital equipment investment is a business that requires consideration of many factors and characteristics. Do you need a machine that can meet current manufacturing needs, or do you want to invest in next-generation features? These are the questions that shopkeepers have been asking themselves when buying a coil front machine. However, research on uncoilers has received little attention.

If you are looking for any machine that runs with a coil, you will undoubtedly need an uncoiler (or decoiler as it is sometimes called). Whether you have roll forming, stamping, or slitting, an uncoiler is needed to unwind the coil for the next process; there really is no other way. Ensuring that the uncoiler meets the needs of your workshop and project is critical to keeping the coiler in shape, because the machine cannot run without material.

In the past 30 years, the industry has undergone great changes, but the uncoiler has always been designed according to the specifications of the steel coil industry. Thirty years ago, the standard outer diameter (OD) of steel coils was 48 inches. As the degree of customization of the machine became higher and higher, the project also required different options, and the length of the coil was adjusted to 60 inches, and then to 72 inches. Nowadays, manufacturers occasionally use sizes above 84-in.coils. Therefore, the uncoiler must adapt to changing coil consumption.

Uncoilers are widely used in the roll forming industry. Today's rollers have more features and capabilities than their predecessors. For example, 30 years ago, roll mills could run at 50 feet per minute (FPM). Now they can run to 500 FPM. This change in roll shape production also increases the capacity and basic range of decoiler options. Merely choosing any standard decoiler is not enough; many factors and functions need to be considered to ensure that the store’s needs are met.

Choosing the right uncoiler

The uncoiler manufacturer offers a variety of options to ensure that the roll forming process can be optimized. When choosing a decoiler, please keep these specifications in mind:

The weight of the coil

Inner diameter and outer diameter of the coil

Coil width

Coil thickness (minimum and maximum)

Number of coils loaded

Roll speed and coil change time

Footprint

Budget

Application/Next Process

You also need to consider the type of project you will be working on and the materials you will use.

It all depends on what you want to run on the roll former, including whether the coil is pre-painted, galvanized, or stainless steel. These specifications will determine the decoiler function you need.

Manufacturers usually don't realize how useful the decoiler is until they realize that, depending on the size of the coil, they can change it 6 to 8 times or more per day. There is a second coil ready and waiting for the machine, eliminating the immediate need for a forklift or crane to load the coil, once the first one is out of the material. The uncoiler plays a vital role in the roll forming environment, especially in large-scale operations, the uncoiler may require 8 hours of shifts to form parts.

When investing in a uncoiler machine, it is important to understand the current specifications and functions. However, it is also important to consider the future use of the machine and what possible future projects will on the roll former. These are all factors that need to be considered accordingly, and really help determine the appropriate uncoiler.

What Is Wear Resistance Steel

Abrasion resistant steel is a steel material with strong wear resistance containing chemical elements such as silicon, manganese, chromium, copper, vanadium and so on.

Production process of wear resistance steel

Wear resistance steels are all smelted by electric furnaces or converters, and most of the products are castings. In recent years, hot-worked materials such as forging and rolling are increasing. The production method of wear resistance steel parts used in general machinery is not much different from other workpieces, but there should be requirements in terms of heat treatment process or surface treatment process to meet the requirements of ensuring wear resistance. For those steel parts whose material metallurgical purity significantly affects wear resistance, refining measures should be taken, and limit requirements for harmful impurities and gases should be put forward. The number, shape and distribution of the second phase outside the matrix often have a significant impact on the wear resistance of steel parts. At this time, it is necessary to coordinate the design of the chemical composition of the steel, smelting, thermal processing, heat treatment (including thermomechanical treatment), etc. Consider it in order to achieve the requirements of improving wear resistance from the aspect of metallurgical factors.

Strengthening technology of wear resistance steel

Wear is a process that occurs on the surface of the workpiece, so it is very important to strengthen the surface of the workpiece. The surface strengthening technology of steel has a long history. For example, the carburizing technology can be traced back to the Han Dynasty in China at least two or more years ago, and the carbonitriding process has been recorded in Chinese history books more than a thousand years ago. In recent decades, various surface strengthening technologies and equipment have developed rapidly. Taking necessary surface strengthening and surface modification measures can not only save a lot of raw materials, but also give the workpiece surface layer a variety of special structure and performance of materials so as to obtain the most excellent wear resistance and huge economic benefits. Today, surface strengthening technology has become an important development direction in the research and application of wear resistance steel(including wear-resistant materials).

Process development of wear resistant steel

In recent years, the surface strengthening (wetting) technology of iron and steel materials has developed rapidly, and new technologies and new processes have emerged one after another. Different surface strengthening technologies can be selected for different needs to improve the wear resistance of steel parts under various types of wear conditions. Use cheaper base materials to make workpieces instead of expensive alloy steels. Carburizing, carbonitriding, nitriding and other processes are still the main measures to strengthen mechanical parts. In addition, casting processes such as infiltration and composite casting are also used in the manufacture of wear resistance steel parts.

Production Capacity Of Vibrating Screen

The more products you plan to sort, the more surfaces you need to filter. The most immediate symptom of a screen that is too small is that its effectiveness is reduced because it cannot let so many particles pass through the holes.

On the other hand, the smaller the size to be sorted, the more surface is required, because the smaller the hole, the less the number of products that can pass.

Vibration frequency of vibrating screen

As a general rule for large classification, low-frequency and large-amplitude vibrations are best, while fine-classified high-frequency and small-amplitude vibrations are best. In other words, if the particle is large, a slow and wide movement is better, in this case the particle jumps are few but large, if it is small, it is smaller than many jumps but smaller. This is a problem that the particles do not pass through several single hop holes.

The importance of feeding properly

In the screen, as in any sorter, it is necessary to use the width of the entire work surface from the beginning. If the product falls on the screen surface "pile", the particles at the top of the pile will not touch the screen or the screen element until the pile is vibrated and disappears. When this happened, it had already crossed half of the earth's surface. In other words, we wasted the surface and caused a very important production loss. At the same time, the area where the piles are located will also be severely worn, and additional maintenance costs will follow. It also increases the risk of clogging, especially for low-density products, if the pile is much higher. This is meaningless, it is impossible to accept correct screening.

This is why it is necessary to pay attention to the implementation and design of the pipes that dump the product on the screen, and use auxiliary means such as vibrating distributors when necessary.

Good screen and bad screen

A good vibrating screen must be reliable, minimize wear and maintenance, and have strong vibration like any vibrating screen: the more it vibrates, the better it goes, that is, it gives more production and efficiency.

On the other hand, most "bad" screens are not really bad, but not suitable for use: if the product is wet and sticky, it will stick to the metal screen instead of the polyurethane screen. If it is dry and fine, the screen should be dust-proof. If you are sieving large and heavy particles, the sieve should be very strong. If it is very sturdy and used with a good product, it will consume more power and maintenance costs than required.

The combinations are endless, and a good choice, suitable for use at the beginning, will save the user from having to remember the machine again in life, or at least until he needs to install another screen.
