Worried about appropriate torque? Check this

In the industry, there are numerous machines in different industries that help to carry out different activities related to production and other important processes. There are lots of industries where thousands of machines are used. In each of these machines, lots of nuts and bolts are used that hold various parts of machines which are important to carry out different processes. For an operator to have the machine in a perfect condition is very important. He needs to carry out maintenance activities at a regular interval that can help to get the processes done in its true sense.

The device:

The wrench which is used to fix the nut and bolt is a great help to the operators who need to run the machines. To fix the nuts and bolts for moving the machine are of great importance. They need to be removed or fixed as and when necessary for the process as well as the maintenance. The torque wrenches manufacturers offer many useful devices that can help the operators to provide the exact amount of torque to fix or remove the nuts and bolts. They are made with scientific designs and provide tremendous quality of work when it comes to applying the torque to the concerned machine. They are made of best quality material alloys which can offer complete value for money spent on them. Hence, with the help of this tool one can apply the right amount of torque to fix the nuts and bolts and run the machine smoothly.

A torque wrench is the best device that eases the task of fixing the nuts and bolts. For every machine, the proper amount of torque on nuts and bolts is much required and hence the user needs to fix the nut and bolt in a manner that the machine can work perfectly. A bolt or nut fixed with much torque can pressurise the machine, and hence the machine cannot function perfectly. If the torque is less than required, the parts may not move as per expectation, and hence it can affect the production capacity again. Therefore, it is much important to fix the machine nuts and bolts as per the required amount.

Application of the device and availability of the same:

The manual application of torque may not be that much accurate, and hence the use of the automatic torque wrench can be much helpful. The user can fix the torque on the wrench that can help him to move the same to the set level. It helps to fix the nuts and bolts easily. The user can get the same from the local market as in themajority of the cities; there are lots of quality shops that sell such devices. One can also check the same in the online stores also. The manufacturers of the device also sell them on their site where the probable buyer can check the description as well as images and see if he wants to go for the same. One can easily place the order on such sites and ask the delivery of the same at the doorstep.

Different Types of Torque Wrenches

The tool used specifically to tighten nuts and bolts to the correct amount, we call as a torque wrench. This helps the worker from over-tightening the nuts especially of the steam pipes and mains of the water system. Using a torque wrench, an operator can measure the amount of torque he or she applies while tightening.

Method of application

By tightening all the nuts by the same amount, one can make sure the system load is uniform and thus the stress distribution is even. However, the drawback in this system is that some nuts may have extra friction on the bolt and this will show up as extra tension. The measurement of the bolt tension will provide the most accurate reading but since one cannot always do this, one must resort to measuring the nut torque.

Different Types of Torque Wrenches

One sees torque wrenches manufacturers make several types of wrenches. The most popular ones are these:

1. Adjustable Click Torque Wrenches: These use a calibrated clutch mechanism to measure the torque. Most common method is the spring-ball system. Here the ball is held in tension by a spring. You find the tension graduation in torque units. By setting the reading to the desired value, the spring pushes until you reach the value. At this point, the ball release takes place and the tension disappears. This is simple and accurate. One finds it safe to use.
2. Square Drive Torque Wrenches: We use this torque wrenches to get consistent torque output. These have 360° swivel manifold with couplers of the screw lock type. You can prevent lock-on on tool by providing fine ratchets. The advantage of this type of wrench is reliability, safety, and durability. They have lesser moving parts and a faster stroke. You get accurate repeatability with this. If needed, you can also perform hands-off operation.
3. Beam Type Torque Wrenches: In this type of torque wrench, two beams come into play. The first one is a handle that serves as a lever for applying the torque. The second one bends in proportion to the torque applied. The scale at the end of the beam will show how much torque we apply at any point of time. The advantage of this type of wrench is the simplicity. The equipment is light and the readings are accurate. If you want more accuracy, you can mount a dial gauge on the beams to get the reading.
4. Slipper Type Torque Wrenches: This type of torque wrench has cam and a roller. We attach the driver to the cam while the roller pushes against it, locking it in place. We can adjust the pressure point in this manner to a prescribed value so that when we reach that point, the cam will roll and the roller will slip, and the nut tightening will stop. In this way, we tighten the nut to the set value and not beyond.
5. Programmable Wrenches: These use an angle measurement gyroscope and electronic torque wrench reading mechanism. Since the torque measurement is in-situ, one can analyse points of stress where we have final torque, prevail torque, and breakaway torque. At the same time, the angel of tightening is always monitored. You require this kind of mechanism in automobile parts tightening to maintain constant stress in all the parts.

The Perfect Turn with Torque Wrenches…!!!

Applying accurate torque on fasteners is crucial in all assembly operations. Failing to do so can result in stripped threads, premature loosening or broken fasteners, often, it can result in leaking joints in automobiles. A torque wrench is a device which is intended to apply specified torque on the fastener.

Most torque wrenches manufacturers come up with four types of torque wrenches which are detailed as below:

• Standard model: These models are manufactured to deliver a torque in the range of 0.3kg.mts to 275kg.mts.
• Production torque wrenches: As the name suggests they be handy in heavy production firms. A particular torque is pre-set in these wrenches which can be employed for the repetitive production applications.
• Ratchet head model: A ratchet mechanism is employed in their manufacture which can enable them to function effectively in confined areas.
• Open jaw fixed type wrenches: The working torque is predetermined as in case of production torque wrenches. It can be productive when using at places where the vertical clearance is restricted. They are highly suitable for turning nuts.

Applications:

• Automobiles
• Machine maintenance
• Construction
• Oil field
• Compressor/ generator

The torque wrench can be applied at any place where ever, the effect of torque is considered strongly.

Operating Tips:

• Hold the wrench at the centre and pull it smoothly and steadily.
• The pressure should be released once the required torque is reached.
• Assemblies, which consist of multiple fasteners should be operated little at a time.
• If the bolt is already tightened, never apply a torque wrench on it.
• These devices must be calibrated at least once in a year.

Safety Tips:

• Safety goggles must be used to protect eyes.
• Damaging equipment like hammers shouldn’t be used.
• Do not exceed the rated torque.
• Before every use check out for cracks and damages of the tool.

Specifications:

The specifications of the torque wrench can be helpful in choosing the perfect one for the required application.

• Maximum torque output
• Input drive size
• Output drive size
• Tool type

Important tools contributing to better productivity and efficiency of industries

There are many different types of industrial tools found in various industries. Without these tools, industries cannot run smoothly and deliver their best efficiency and productivity. The industrial tools are the best partners of the workers working in an industry as they help workers in delivering their full efficiency and increase their productivity. With proper tools and equipments, a worker can perform a task in a very less time and in very better way. The industrial tools determine the productivity of the industry and quality of the products and services, as well. Here are some of the common industrial tools that are used in almost every industry on regular basis for various tasks.

Welding sets

Welding is done in almost all industries for joining two metal parts. The welding is the process in which molten metal is inserted between two metal parts using high electric current or gas to provide a strong and long lasting joint. There are many types of welding processes used in industries such as electric welding, gas welding, arc welding, MIG welding. The welding sets are available in variable sizes and capacities. You can also find portable welding sets, which can be moved easily from one part of company to another.

Grinders

Grinders are basically used for removing a thin layer of metal from various products and metal parts. The process of grinding is performed for various purposes such as giving a smooth and shiny texture to the products, reduce the size of a metal part or eliminate the open or sharp ends of a metal part to make it smooth. There are many types of grinders used in various industries such as cylindrical grinders, hand grinders and angle grinders. The angle grinders are used for cutting heavy metal rods and angles.

Wrenches

Bolting is a major operation that is performed in every industry in daily basis. It is important to perform this operation in an effective way to ensure best quality of the product and safety at workplace. In order to do so, proper tools are necessary, and wrenches are the most appropriate tools to do it. The wrenches are available in various types such as simple wrenches, impact wrenches, torque wrenches and special purpose wrenches such as pipe wrenches. The torque wrenches are the most used wrenches in the industries where you need very high power and high level of accuracy. The torque wrenches manufacturers provide you a digital or analogue metre, which can be used to measure the force applied on a fastener. In this way, you can decide when you should stop the application of force on the fastener to avoid over tightening as it can shatter the fastener.

Apart from these, there are many other tools such as nut splitters, tool balancers, etc. which make the industries and its workers efficient and more productive.

Industrial tools making industries efficient and productive

Tools are lifeline of any industry and most of the operations are dependent on these tools and equipments. It is difficult to imagine an industry without proper tools and equipments. The industrial tools not only improve the productivity and efficiency of the workers, but also provide you accurate and precise working of very high degree in very less time. Tools are considered to be the best friend of a worker in any industry.

There is a vast range of tools that are used in an industry varying from portable small tools, which are handheld to heavy fixed tools. The fixed tools are very heavy and are difficult to move frequently. They are fixed in one section of an industry. They are used for heavy operations in which large amount of force are needed. For example, sheet cutting, lifting heavy goods, etc.

The handheld tools are used for lighter operations such as bolting, welding, cutting etc. They are light weight and can be easily carried by the workers to the various sections of an industrial plant.

Some the most commonly used handheld tools that are used in the modern industry are given below.

Surface grinders

A surface grinder is the tool that is used for creating a smooth and shining surface on a finished product. This smooth texture and shining surface determines the quality of a product. The surface grinder files out the upper layer of metal, which is rusted or damaged. After the top layer of metal is removed, the shiny layer is obtained, which gives a mirror finish to the product. An angle grinder is also used in industries, which is a bit heavier version of a surface grinder. It used for cutting heavy iron rods, and steel angles. They are ideal for industries where there is no facility for cutting heavy bars and angles of steel.

Drilling machines

A drilling machine is used for making holes of variable dimensions in different surfaces. Both fixed and portable drills are found in most of the industries. Portable drills are used for those areas, which are inaccessible for fixed rills. Holes are made using drills with very high precision. The drill bits are especially designed to work on high speed and temperature so that they could withstand the high pressure exerted on them during operation.

Wrenches

Wrenches are used extensively in industries for bolting operations. There are basically two types of wrenches used in industries namely impact wrenches and torque wrenches. Impact wrenches use a heavy impact force to turn the fasteners while the torque wrenches use heavy radial force called torque to generate circular motion in the fasteners. Torque wrench manufacturers design it in such a way that they provide you maximum precision and accuracy. They are provided with a gauge on which you can easily measure the force applied so that you could get higher accuracy.
