Types of closed die forging press

A closed die forging press refers to a method for shaping metal. In this process, heated metal is placed in a die block. Then, a ram drives down and squashes the metal into the shape of the die block. The metal will have a shape after the process that is very similar to the block.

There are multiple types of closed die forging presses:

• Hydraulic Closed Die Forging Presses

  Hydraulic closed die forging presses utilize hydraulic cylinders to generate and control forging force. Their versatility and control make them suited for diverse industries. These machines shape metal by applying high pressure to contracted cylinders. This hydraulic pressure drives a ram downward in the machine, which then molds the metal workpiece into a predetermined shape. The use of hydraulic force ensures consistent and uniform shaping of the metal. This method is particularly useful for complex shapes requiring high precision. Manufacturing plants often use hydraulic closed die forging presses for their flexibility and reliability in metal shaping.

• Mechanical Hammer Closed Die Forging

  Mechanical hammers work by dropping a predetermined weight on the metal workpiece to shape it according to the closed die's shape. The drop of weight is controlled by a mechanical linkage and can change based on the machine’s configuration. Mechanical hammer forging operates with a series of gears, motors, and clutches. These components work together to control the speed, frequency, and weight of the hammer. The force generated from the falling hammer reshapes the metal into desired forms. This method is traditionally used for heavier metals but is now applied to lighter metals for greater efficiency and production rates.

• Drop Forge Press

  A drop forge press functions by dropping a heavy block (sometimes referred to as the forging hammer) onto the metal workpiece until it assumes the shape of the die. They can also be called drop hammer presses. It is essential to note that drop forge presses differ from mechanical hammer closed die forgings. Drop forge presses utilize gravity while utilizing hammers, as mentioned before, rely on force generated from clutched motors and gears.

Specifications and maintenance of closed die forging presses

Specifications

The following specifications are essential when choosing a closed die forging press.

• Force: The force or tonnage a closed die forging press generates is substantial. Machines with a tonnage of 25-1000 can be found on the market.
• Die sizes: The die sizes will determine the shape and size of the forged metal. Generally, the die sizes range from 10-36 inches, depending on the machine model.
• Speed: Speed is the number of strokes per minute. Speed affects productivity levels. Generally, the speed ranges from 60 to 150 strokes per minute.
• Energy source: The energy source can be hydraulic or mechanical. Hydraulic presses use a fluid-based system, while a mechanical press relies on an electric motor.
• Machine dimensions: The machine dimension will determine how much space the machine takes up. The overall height will also affect the stacking during the shipment of goods.
• Machine weight: The forging press weight will affect the shipment method.

Maintenance

Regular maintenance of a closed die forging press can help to maximize uptime and productivity. Here are some tips for maintenance.

• Weekly die maintenance: Operators should check the dies for signs of wear, damage, or buildup of foreign material. Any flaws or roughness should be polished or corrected to avoid impacting the forged part's surface finish and overall quality.
• Lubrication: Regular lubrication is essential for moving parts. Identify the points required for lubrication and the periodicity as per the manufacturer's instructions. Clean the area before lubricating to avoid contamination.
• Safety device checks: The safety devices should be inspected periodically to ensure they are functioning correctly. Any safety guard or emergency stop button should be checked for proper operation. This will help to reduce the risk of accidents.
• Daily fluid checks: The hydraulic fluids should be checked at least once daily before using closed die forging hydraulics. Look for any leaks in the lines, hoses, or fittings. Ensure that the hydraulic system is free from contamination. A clean, functional hydraulic system is critical for the machine's longevity and performance.
• Air filters: Air filters on closed die forging presses using pneumatic systems must be inspected. Dirt and contaminants can adversely affect component functions.

How to choose a closed die forging press

When purchasing a closed die forging press, buyers need to consider several factors that affect both performance and production efficiency.

• Product complexity

  First, the buyer should determine if the product can be created through open-die forging. If the desired shape of the final product has a simpler design, a closed-die forging press should only be considered for those items. The buyer should consider each product they aim to manufacture and see if open or closed-die forging applies to it.

• Required strength

  A key reason manufacturers use the closed-die forging process is to achieve great strength and durability in parts required to have high stress. The buyer should assess each part they wish to create with the forging method and determine if strength and durability are essential requirements for it.

• Production volume and the cost of dies

  The forging process can encounter high initial costs due to the forging dies. The costs of these items are known to be higher with the closed-die method. If a manufacturer wants to create several product units of the same type, the closed-die forging method can be the more cost-efficient way to mass-produce items.

• Material variety

  The closed-die forging process is compatible with several metal materials, such as titanium, brass, carbon steel, stainless steel, etc. When choosing a machine for sale, the buyer should consider what material they will use during production. They should look at the material compatibility and ensure it works with the forging machine.

Closed die forging press Q & A

Q1: What is the difference between closed-die and open-die forging?

A1: In closed-die forging, the metal is shaped in enclosed dies, which provides better dimensional accuracy and surface finish. Closed-die forging also allows for more complex shapes. On the other hand, open-die forging uses flat dies or open cavities. While both processes improve the strength of the metal, closed-die forging offers better precision.

Q2: What materials are suitable for closed-die forging?

A2: A wide range of metals can be closed die-forged, including carbon steel, alloy steel, stainless steel, aluminum, copper, brass, titanium, etc. Each material has its own unique properties and advantages. Titanium alloy closed die forging is usually the most expensive forging process but also produces the most durable parts, so it is commonly used in the aerospace industry.

Q3: What are the limitations of closed-die forging?

A3: Closed die forging has its limitations. The main limitation is that it is only suitable for mass production. The initial cost is high because the dies are expensive to design and manufacture. If the number of pieces needed is not large, open die forging or other forging techniques is a better choice.

Q4: What are some applications of closed-die forging?

A4: Closed-die forging is widely used in various industries. The automotive sector relies heavily on closed-die forging to produce components such as crankshafts, gears, axle shafts, and wheel hubs. Aerospace also makes extensive use of this method to create parts like turbine disks, rods, and aircraft landing gear. Other industries that use closed-die forging include machinery manufacturing, oil and gas, defense and military, and medical.
