The following points highlight the top nine methods adopted for forging. The methods are: 1. Drop Forging 2. Press Forging 3. Hammer and Press Forgings 4. Hot Bar Forging 5. Upset Forging 6. Electrical Upset Forging 7. Swing Forging 8. Cored Forging 9. Rotary Forging. Method # 1. Drop Forging: The difference between drop forging and smith forging is that [...]
Forging hammers are commonly used for impression-die forging and can be used for a variety of forging operations. In forging hammers a heavy ram containing the upper die is lifted by steam pressure or air pressure, then driven or allowed to fall on the workpiece which is placed on the bottom die, which in turn is supported on the anvil. [...]
In this article we will discuss about the general design consideration in forging of metals. Factors Influencing the Design of a Forging: The various factors which require due consideration and which influence the design of a forging are: (i) Shape and size, (ii) Grade and composition of metal, (iii) Quantity required, (iv) Subsequent processing and heat-treatment, and (v) End use. [...]
The frictional force of the rolls on the material acts in the direction of material movement on the entry side of the neutral point, but on the exit side of the neutral point the frictional force of the rolls on the material acts in the reverse direction of the material movement as shown in Fig. 5.2. It is difficult to [...]
