According to the Collins dictionaryit is the process of producing various parts by hammering. The magnitude of the force will depend on the type of metal and type of machines among other factors. Thus, it can be classified broadly as hot or cold forging. This refers to the metal forming temperature. You will understand it in next chapter Chapter 2: Forging Process Traditional vs. At times, one may refer to it as primitive blacksmith — Iron Age. This has been replaced by machines. It was during the industrial revolution that man adopted the use of machines.
They can forge both small and large equipment. That is, from small bolts to turbine rotors. Despite being an ancient technology, it has been adopted even in the modern metal part manufacturing.
In fact, with these machines, it is possible to obtain very complex shapes. By deforming the work piece, one can create a desired geometrical shape. In most industries, the individual metals must be tested to determine the technique that should be adopted. Therefore, the technician or the engineer should understand the basic principles that govern the entire process. It is important that you understand every aspect of the entire process to be able to make informed decisions.
Forging process refers to all the steps that engineers and technicians use to shape the metal into a desired shape. In the modern manufacturing process, it is to produce complex shapes with minimal secondary operations.
This may involve a number of metal fabrication techniques. There are a number of factors you need to consider in any metal forging works. Any technique adopted for a manufacturing process should relate to the exact specifications of the final product. It is worth considering how a given technique will affect the final grain structure of the metal.
To get components with improved physical properties, it is important that the technique aims at refining grain structure of the metals.
Normally, during plastic deformation ,metals tend to change their structural composition. Before any metal fabricationthe grow book and equipment guide pdf free download, to get an accurate component ,you will always need a CAD drawing to confirm all details like shape, size etc.
Sometime you even need the 3 D print to see how your components will look like. At times, deep drawing may not be a single process. It may involve a series of process such as: blanking, drawing, piercing and trimming.
This forging technique is mainly used to increase the cross sectional area of metal at the expense of length. In this metal forging technique, the cross-sectional area of metal decreases as the length of the metal is increased. A reasonable amount of force is applied to the work piece when the bottom of the fuller is maintained at an angle hole. In this process, the metal is manipulated into the desired shape by striking it between two dies.
This manufacturing process is suitable in operations where the grow book and equipment guide pdf free download length of the final product should be reduced to a desired shape.
In most cases, the final product has a reduced cross section that can be used in threading, tapping or threading. In summary, there is some of the most common metal forging process.
Video : Die forging process open and closed die. Hot Forging Vs. Cold Forging. Furthermore, the grow book and equipment guide pdf free download, the type of forging machine and equipment forms an integral part when it comes to classifying different types of forging operations.
In normal industrial setup, there are four basic types of machines. Working principle of these hammers is based on a potential energy that is converted to a kinetic energy and then to a deformation energy. This is one of the reasons why they are also referred to as the gravity drop hammers or drop hammers. This implies that, the magnitude of force will depend on the weight of the hammer and the height.
This is one of the main reasons why it is referred to as the energy restricted machine. That is, a greater percentage deforms work piece while others are lost in the form of noise, foundation shock, the grow book and equipment guide pdf free download, noise and heat. This makes it important to define the fraction of energy generated by hammer that is utilized efficiently.
Normally, the efficiency is defined by the magnitude of deformation that takes place during any stroke. This can be defined in the range: 0. Where, Ƞ denotes the efficiency of the forging hammer. The efficiency of the forging hammer is based on the analysis of the amount of energy generated and the amount utilized. Where, w is the weight of the hammer, A is the area of the piston, P is the steam or air pressure while H is the grow book and equipment guide pdf free download drop height.
Where σ is the true stress and ε is the true strain. However, it is important to note that the initial cost of the forging equipment is slightly expensive. These machines use hydraulic pressure to move the piston. These machines are also associated with longer contact time, especially at the die and metal interface. Hydraulic presses are more accurate. This is the main reason why they are used in applications that require the grow book and equipment guide pdf free download tight tolerances.
Again, it is worth noting that, they are more expensive than hammers and mechanical presses. These machines have crank presses with the ability to translate rotary motion to a reciprocating linear motion.
Depending on specified requirements, this will result in a total energy that can forge a work piece. Where W is the total energy required, I is the moment of inertia of the flying wheel, ω is the angular velocity, ωo is the original value while the ωf is after the deformation of the work piece. Mechanical presses are distinguished by the fact that, their ram stroke is relatively shorter than either the hydraulic press or hammer.
In most cases, these presses are always rated based on the magnitude of force they can develop at the end of each stroke. In most cases, establishing the right force should be based on the following key criteria:.
Drop Forging Hammers. Forging Machinery. This implies, one has to be very specific on chemical and physical properties of the individual metals. It is a copper alloy that offers a wide range of benefits and has been incorporated in a number of applications. These are some of the main reasons why brass is commonly used in a number of industrial applications. It is the most forgeable. There are quite a number of alloy steel forging that are used in different manufacturing industries.
Some of the most popular alloys include theand There are other types of steels with nearly the same chemical and physical properties. However, there are some variations based on the elements contained. Steel forging companies can choose from three main types of steels:.
Carbon the grow book and equipment guide pdf free download have similar properties of iron. Adding more carbon makes it difficult to weld or deform and cracks easily. Which will make it difficult to forge. Alloy steels have greater strength, hardness, wear resistance and enhanced toughness. Often you may need additional heat treatment to achieve all these. Stainless steels contain higher amount of chromium.
They are corrosion resistant and do not rust. It is upon the metal fabrication technician to opt for a metal that suits a specific application. By adopting right technique, metal forging company can produce stronger and durable steel parts than cast or machined parts. With right forging techniquesteel parts will possess the following key properties:. Forged steel parts are used in a wide range of applications that may include manufacturing cranes, cables, hydraulic press, shafts and axles for drives.
Aluminum has become popular across very many industries due to its light weight. Check one list from slideshare, the grow book and equipment guide pdf free download. Aluminum forging is popular due to the superior physical and chemical properties. This makes it a perfect choice for a number of applications such as automotive, wheels, airframes and panels. This is the main reason why they are used in the petrochemical and marine industries.
In fact, most fasteners in these industries are manufactured from aluminum. It is a versatile metal that be manufactured with a wide range of metal forging processes. Its soft compared to other materials such as iron.
This reduces the production cost. In most industries, iron is considered a super alloy. This is due to the fact that, the forged parts are mainly used in high temperature applications. Iron forged parts are less expensive as compared to other alloys such as the nickel or cobalt-based alloys.
In addition to these, the iron based alloys can be hot or cold worked.
