Power Press

What does a press machine do?

Power press is metalworking machines primarily used to cut, punch, or shape metal using tools (dies) mounted on a slide. and bed. The slide has a controlled reciprocating motion to and from the surface of the bed and at right angles to it. Power Press

What are the specifications of the press machine?

Working capacity: The capacity of mechanical presses varies from 50 tons to 4000 tons. On the other hand, the capacity of a hydraulic press is determined by the area of ​​the piston multiplied by the oil pressure in the cylinder. The capacity of the hydraulic press varies from 100 tons to 40,000 tons.

What energy system is used in presses?

By the action of the press. An impact force is applied to the surface of the metal matrix, which is subsequently deformed into the desired shape. Mechanical presses use a reciprocating crank mechanism controlled by a flywheel clutch.

How does a mechanical press work?

The working principle of a mechanical press is to change the rotational power of the electric motor into translational power. Which drives the press mechanism. The power source of a mechanical press is usually a motor.

What are the parts of a press?

Each press consists of a frame, bed or support plate, And a reciprocating member called a ram or chute that forces the work material through special tools attached to the ram and bed.

What is the principle of hydraulic press?

Image result The hydraulic press works on the principle of Pascal’s law, which states that when pressure is applied to a closed fluid, the pressure in the entire fluid changes. Inside the hydraulic press is a piston that acts as a pump that provides a slight mechanical force to a small area of ​​the sample.

Is a hydraulic press a motor press?

A hydraulic press presses fluid, which in turn produces energy. It mainly consists of a piston, a hollow cylinder and a drive unit/pump. The pump moves the piston, which increases the internal pressure of the liquid.

What are the 7 parts of a press release?

What are the advantages of a hydraulic press?

Hydraulic presses have built-in overload protection, which means that there is a set pressure and the press will not exceed this limit. The relief valve opens when its limit is reached, so you don’t have to worry about overloading or damaging the weight.

What pump used for a hydraulic press?

Pump. The three types of hydraulic pumps are vane, gear, and piston, with piston pumps being the most commonly used. Hydraulic press pumps are positive displacement pumps, meaning they deliver a constant amount of fluid in each pump cycle.

How do you measure a hydraulic press?

Use the formula: Area is equal to 3.14 times the square of the diameter divided by four. For example, if the diameter of the piston is 4 inches, then you multiply 3.14 times 4 inches by 4 inches divided by 4. So the area is 12.56 square inches.

What does a punch press do?

punch presses, a machine that changes the size or shape of a piece of material, usually sheet metal, by pressing it against a die where the workpiece is held. The shape and construction of the die determines the shape produce by the workpiece.

What exactly is a Press?

Presses are driven by a servo motor. Like a traditional press. It designed for forming. The ability to control ram position, stroke length, shear profile, load value, torque. And speed makes them very effective. There are extremely low energy losses during operation.  Presses are high torque machines. They are capable of producing full force output pressure at every point of operation. This makes it ideal for processing high strength materials. Full control allows them to shaped with high precision. Secondary processes such as surface treatment are limited.

Full control of direct actions achieved with a closed-loop feedback system. The system equipped with ram sensors so cycle time. And load are controlled more precisely. As a result, a  press can perform tasks that require different torque, speed, feed and stroke. Common uses include pressing, riveting, sealing, bending, drawing, forming, cutting, punching to name a few.

How does an electric press work?

The operation of the ram is very different from a conventional mechanical press.  There a lead screw and nut rather than a cylinder that moves the ram.

Drive shaft

The  motor connect to the lead screw with a belt. As the motor drive shaft rotates, the belt pulls the lead screw to rotate. As the lead screw rotates, the nut inside the cylinder moves along the lead screw. Unlike typical electric motors, a servo motor can rotate the drive shaft clockwise or counterclockwise. It controls the direction of rotation of the lead screw and subsequently the pressure and thrust of the ram. Below is a video showing how the press works.

Types of press with

● Hydraulic Hydraulic presses work on the basis of Pascal’s law. The pressure apply to the close environment distributed evenly without energy loss. In other words, the pressure inside a closed system is constant. In conventional hydraulic presses. The piston creates force in a smaller cylinder. The second piston creates more force on the larger cylinder. Compared to conventional hydraulic presses, -hydraulic presses with high-performance motors achieve higher feed rates in the forming process. It often use for casting, casting, punching and metal forming. The hydraulic press is popular in industrial manufacturing for its ability to create complex shapes with less material waste.

● Ball screw This type of presses uses ball screws to reduce friction. Unlike conventional screw presses. The caliper speed can change in the forming process without a clutch or flywheel. The advantage is that full slide speed and maximum force can apply in any position. It can use in a variety of applications to meet the needs of long stroke applications such as extrusion.

Ball screw presses are also ideal for forming applications.

That require fast movement at the end of the process. Regarding the maximum load of the ball screw type, you need to know the load capacity of the ball screw as well as the reduction of the belt. By increasing the number of motors and spindles, you can increase the performance of the machine.

● Handle motor driven crank presses are an economical alternative to ball screw types. The high torque motor of the crank press can attach directly to the drive shaft. It is very similar to a traditional mechanical press. The main difference being the removal of the flywheel and clutch. Works with two connecting rods to improve performance for high load applications.

● Connection The clutch mechanism reduces feed rate and achieves higher engine load capacity near bottom dead center. By slowing the feed rate within the stroke, they can increase the approach and return rates. Another advantage is the ability to sustain a high load during a relatively long processing cycle.
