Riveting System Nowadays

Riveting systems come as a very important utility in these days industries. The process implies the worker to set up the rivet in the nose of the tool to actuate it. However, times changes and  these days the worker is excluded from the whole operation. Riveting system reduces the overall costs in a company. They come in a wide variety of models, depending on their structure and features.

Riveting refers to the operation where through two or more metal sheets or other thin profiles are combined through various systems. The riveting systems can be split in multiple categories, by various criteria.

  • Judging from a technological temperature point of view, the most common riveting systems are the room temperature ones. The rivets are usually smaller than 12 mm in diameter. The systems may also be used at hot temperatures, for a better anchorage. It only depends on the metal that is used and the necessity of the job.
  • From the working style point of view, the rivet systems may be manual or mechanical. The mechanical riveting systems imply large scale rivets, which are usually larger than 12 mm in diameter.
  • The purpose and the destination of the job is also very important in riveting systems classification. Some rivets are used for resistance. This implies metallic bridges and rolling bridges first of all. Cranes skeletons are also very rich in rivets. Another category defined by the purpose of the job implies the sealing rivets. Such systems are mostly used for smaller scale objects, such as steam boilers or various recipients under pressure. You may also encounter resistance and sealing rivets. However, they are pretty rare and mostly common in particular orders.

Riveting systems nowadays come with many advantages.

  • They present extra safety in the superior exploitation of ball iron. This includes various constructions under dynamic burdens, such as bridges or naval ships.
  • They also allow combinations between unweldable materials. Some materials may be weldable, but the temperature required diminishes the effect of thermal treatments.

Just like anything else, nothing is perfect. So riveting systems nowadays also come with a few side effects.

  • They have a high consumption of materials.
  • The working conditions are very stressful due to the very high noise.
  • The resistance of the worked parts diminishes in various sections.
  • The sealing of the new construction also losses some of its characteristics and becomes very weak.

The side effects of riveting systems don't seem to be too minor and easy to ignore. Then why are these systems so common in various industries? The answer is pretty simple. They are not like regular workers and they can easily substitute a few workers. Also, they don't need any breaks, so as long as there is someone to take care of them, they can go on and on for days without any problems at all. Their prices come to substitute the workers as well, so they are only recommended for top industries. A good riveting system can easily reach $50,000.

How To Take Care Properly Of Your Metalwork Tools

Metalwork tools are split in two major categories. The first category includes the industrial metalwork tools. They are very advanced and can easily do various jobs with minor help from an engineer. Industrial metalwork tools can easily be referred to as machines. Their prices reach astronomical numbers. If you own such tools, then you probably need a professional to take care of them. They require particular maintenance operations that cannot be done by a regular owner. However, this is a valid statement only if you own a large scale company or you are... An eccentric person.

A regular person interested in metalworking opts for a different category of tools. Most garage owners don't usually use them to host their car inside. Almost every garage has a small area in a corner full of tools. It is a common hobby for men to do various crafting operations. Sometimes they are needed in the house, sometimes they are just fun times. However, such metalwork tools are easier to maintain than industrial machines. Let's see how.

Among the most common tools, hammers and screwdrivers are the easiest to take care of They must be kept out of moisture and if somehow they end up wet, they need to be taken through scrapping operations. However, such unpleasant situations appear over long periods of time, like for instance constant leaks through your garage roof in your tools set. On the other hand, clippers may require more operations. Every once in a while, oil their mechanisms in order to keep them working smoothly. Also, avoid using them for anything else they are not designed for. Especially if you own pneumatic or blading clippers. Blades need to be used for very clear and soft surfaces. Any small particle of dirt may ruin them.

If your passion goes beyond the Sunday fun metal crafting, then you probably need more than just the basic tools. If you are practicing to become a professional or just having a little business going in your garage, you may opt for mechanical or electric tools. They are more expensive, but they can make a better job. They also need particular maintenance operations for a good functionality.

For a proper care of more advanced metal crafting tools, make sure you read their manuals first. It is imperative to avoid going beyond the limits if you care for your tools. Since most of them come with warranty periods, you are basically obliged to resume to exactly what you should do. If somehow you think you are smarter than the manufacturers and start doing your own things, you will lose the warranty. This only means two things - you have a wrecked tool and you need to pay money to fix it, congratulations!

Among the basic maintenance operations for mechanical or electrical tools, you might have to clean them with wet and clean sponges, or use oil for their joints. Make sure you keep them at the temperatures indicated in their manuals and avoid direct sunlight or moisture. Dusty places are also a bad idea for depositing your tools.

Importance Of Taking Safety Precaution Of Metalworking


Metalworking is by far one of the top industries in the world. Metals are everywhere, in one form or another. People deal with it daily, but how many actually think about how it is manufactured? Before getting on the market or being part of most devices, metal goes through more stages. This includes mining and manufacturing. Metalworking isn't only a top industry, but also a very risky one. The risks of mining and manufacturing can only be understood by someone working in this industry. However, the catastrophic accidents you see on the news every year from various parts of the world should give you an idea on these risks.

Safety equipment comes to prevent such issues. Mining implies the biggest risks. Whenever one gets down there, there is always the risk of gases and fire. Gases can be prevented with gas masks, while fire only depends on the workers. Methane, firedamp and other such gases are found in pockets. Sometimes they are inflammable, while other times they simply choke the workers and asphyxiate them. Collapses are also a major risk miners face. Although all the mines are sustained with fake ceilings and resistance columns, the soil is unpredictable. Safety precautions minimize these risks, but never eliminate them completely.

At the surface, the risk of collapses is out of discussion. However, the risks of metal working fluids are a major risk that affect over 1 million workers worldwide in every year. Skin contact doesn't just harm a worker's epidermis, but once the blood gets in contact with such metals, it becomes toxic and can lead to a slow death. Sometimes, workers don't even know that their blood is affected and think that a curing wound is everything they need.

Before involving with such industries, the workers are being instructed on the safety measures and equipment. They are given brochures related to it and are asked to sign for their responsibility, after all their questions and issues are being answered and solved. However, this is not a managers trick to take away the guilt from themselves, as it may seem. There are cases when the workers are the only ones responsible for their wounds or death.

Safety precautions in metalworking are just safety measures. They don't eliminate the risks completely. In most of the cases, the workers are the ones responsible for the errors leading to catastrophes and deaths. Safety equipment is therefore very important. Some aspects like the poisonous gases make it mandatory, although in some cases it is used to help a little with the various errors workers may end up with. If one individual cannot pay proper attention to self when working, the safety equipment may help him out.

Overall, safety precaution is mandatory. It obviously saves life. There are cases when the authorities found living people within days after collapses, without food or water and surrounded by poisonous gases. How did they survive? Obviously, they couldn't resist without their equipment. So even when it comes to catastrophes, you never know when your lucky day is.

Newest Metalworking Heavy Tools


Metalworking tools come in a wide variety of models. If decades ago you would only see some basic non electric tools workers used to kill their time with, these days you can see robotized machines that are just as good or even better and more precise than humans.

Plate rolls for instance are very common, especially metal is highly commercialized in sheets. The most modern such machines include an automatic balancing system and hydraulic cone rolls. They also come with an emergency safety system, in case the worker dealing with them encounters problems. Radial arm drills are also very efficient metalworking tools that take away one responsibility off the workers' back. Years ago, workers have to perform manual drills. Even when they had the right tools, they still had to choose and make the holes themselves. These days, radial arm drills are programmable intelligent machines that only need programming. Basically, a professional engineer can set up the number of holes and the distance or the period of time between two holes. Then, the job is done by the machine, simple like that.

Milling machines are part of the heavy tools category. A milling machine does the job of 7 workers and it never needs to rest. Such machines are recently brought into the metalworking industry and their prices fit with their importance. They can be as expensive as a house. The modern milling machines have independent powered parts, in order to maintain integrity. Therefore, during troubleshooting, the working parts can go on while the damaged one is getting repaired. The same category includes the hydraulic presses. The RK models are the newest metalworking tools on the market. They have 10 to 20 horse-powers and a 100 to 150 tons capacity. In order to help you understand their power, you should know there still are cars manufactured in the 70's that have less horse-powers than a hydraulic press.

CNC lathes are modern micro panthers for production environment or training schools. Therefore, they are created to resist for tests and heavy work. They may come with up to 5 motors and various other smaller engines. CNC milling machines are also one of the newest and most important metalworking tools. The modern machines come tunned with chip augers or coolant wash down.

The prices for these modern tools may be exorbitant. They are obviously intended for major industries who can afford such huge numbers. For instance, the CNC machines can be purchased for around $50,000. Even the daily rent of over $1,000 is worth considering. What makes them so important? In the long run, they have more advantages over workers. They don't need breaks, sleep and they don't ask for monthly wages. In years, they are both more effective and lower in costs. Besides that, although it is said that a machine can never be better than a human, the repeated precision of these professional machines comes to argue against that fact. No surprise the top manufacturers opt for them instead of investing in training and hiring new workers.
