A mechanical press can be used to manufacture a variety of different components. You can choose to use a single geared, Servo, or Overhanging or gap frame presses. There are also Pneumatic die cushions available to suit your needs. Lastly, you can consider a knuckle joint or flywheel-drive press.
Overhanging or gap frame presses
There are several types of mechanical presses available in the market. These machines are used to press metal components. They are available in many different models and designs.
Most of the power presses are actuated by hydraulic energy. However, there are also foot powered kick presses. The size of the press is determined primarily by the work to be done. Some operations may require a higher stroke strength, while others need a lower one.
In order to determine the best machine for your needs, it is important to understand the various types of presses. The major parts of a press include the bed, frame, ram, and drive system.
A servo press is a mechanical straight sided press that uses a servo motor instead of a common inductive motor. It is programmable and can offer higher speeds for various forming applications. In addition, it can provide more forming in a single station.
The servo press also improves accuracy and flexibility. Servo presses use a servo motor to replace a flywheel and brake. This reduces energy consumption and simplifies the transmission chain.
Depending on the application, a servo press can be used for drawing, cutting and embossing. It can work with different dies and can be customized. Compared to a conventional mechanical press, a servo press can deliver more throughput, and can operate at lower speeds during the non-working part of the stroke.
Single-geared mechanical straight sided presses are among the most popular press drives in the automotive industry. These presses can run at continuous speeds as low as 28 SPM. A geared press provides more energy than other types of press, allowing the flywheel to run faster. This allows a greater range of energy availability, particularly in heavy-duty applications.
The size of the flywheel and the distance it travels will determine the amount of energy it can supply. The energy can be used to stamp or pierce parts. It’s also possible to integrate an additional flywheel into the driving system to add extra energy at low speeds.
Knuckle joint presses
The knuckle joint is a mechanical device that is used to connect two cylindrical rods. It allows angular movement between them under a tensile load. As a result, it has a very high system rigidity. This means that it can handle a hefty tensile load without breaking a sweat. In addition, it can reduce the impact shock that would otherwise be experienced when hitting a hard surface.
The knuckle-joint press is a good example of the magic of angular motion. Its main function is to deliver a high amount of force with a very short working stroke. So, it is no surprise that it is also a very good candidate for net shape forming.
Pneumatic die cushion
A draw cushion is a device used in a press to provide the force required to bind the workpiece between the upper die and the blank holder. This force can be programmed into the force profile and is generally a constant value.
Draw cushions are mounted on a press bed. They can be either hydraulic or pneumatic. The type of draw cushion installed depends on the drawing operations that are performed.
For deep-drawing, a pneumatic cushion is preferred. These cushions are manufactured with a greater range of power than hydraulic cushions.
A mechanical straight sided press is a heavy-duty press. It is often used in extruding, stamping, and swaging applications. Depending on the production requirement, it is available in a wide variety of sizes.
A flywheel-drive mechanical straight sided press is used for various operations. Specifically, this type of press is ideal for blanking, piercing, and a variety of other high speed operations. This is due to the dynamic balance of weight in the upper die and press slide.
The major components in a power press are the flywheel, ram, crankshaft, and clutch. They all work together to provide the energy needed to drive the press. These presses are available in a number of different capacities, frame types, and power systems.
Depending on the type of press, the speed of the press can vary from 90 to several hundred strokes per minute. The length of the stroke can also vary. Guides and controls can adjust the power of the ram as necessary.
