Press Machines :

Press machines are majorly used in sheet metal industries for providing any shape or punch to the sheet metal. The Press Machines are designed to use mechanical force or pressure to mold or cut metal. With the use of a press machine, you may muold metal into any shape you want without having to remove any chips.

There are various types of categorizing presses into various categories. We at Rajesh group of company provides two types of Power Press Machines.

 Types according to Power Source :

1. Manually operated or Hand Press or ball press or Fly press

2. Power press

Types according to designs of the frame:

1. Gap Frame Press

2. Inclinable Frame Press

3. Adjustable Bed Frame Press

4. Horning Press

5. Straight Side Press

6. Pillar

Classification according to Power Source :

1. Manually Operated Press Machines :

These machines are the most simple form of Press machine in which press is applied manually. This kind of machine is used when working operations are of thin metal sheet where less force and pressure are required. It is operated manually. These presses are used to perform small operations like piercing, blanking, bending, etc. The types of manual press machines are hand press, ball press, and fly press.

The main parts of the hand press machines are the frame, ram, nut and screw, iron ball, handle, guideway, punch, and die. The cast iron balls are mounted at two ends which are bolted to screw. The ram moves up and down by rotating the arm manually and performing operations. The sheet is placed on the bed, and the ram is equipped with a punch.

2. Power Press Machines:

 These are the most famous machines which are mainly used in workshops. The function is the same as the hand press but the only difference is that the ram is operated by power. The power source of this kind of machine is either an electric motor or engine. 

The ram is equipped with a punch and is used to work on the job that is held on the die block and bolster. The flywheel receives energy from the electric motor, which is then transferred to the ram via a clutch and crankshaft.

Classification according to designs of the frame:

1. Gap Frame Press :

As seen in the above figure, it has the larger frame opening part which indicates the wide gap between ram and bed. It is also called C-Frames machines. This type of machine is beneficial for the accommodation of large workpieces with longer beds as seen in the figure.

2. Inclinable Frame Press:

It is known as inclinable frame press because of the flexibility of the frame. As seen in the figure, the frame is tilted back up to some angle. It’s also known as the open back inclinable press since its rear is open to allow scrap to depart.

3. Adjustable Bed Frame Press:

Because it has a knee-type bed supported on a column-shaped frame, it’s also known as the column and knee-type press. Its bed (knee) can be moved vertically up and down with the use of power screws to any desired height. In comparison to other structures, this construction has a small lack of stiffness. It is depicted in Figure.

4. Horning Press:

It is made out of a vertical frame with an overhanging top that faces the front. The ram control and driving mechanism are housed in the overhanging part. The frame has a horn-shaped front face that serves as a work table.

5. Straight Side Press :

The figure depicts the straight side press. Two vertical stiff frames make up this press machine. These are positioned on two sides of the base and are designed to absorb the ram’s essential stress. The machine can handle heavy work, but sheet metal cannot be fed from the side due to the existence of side frames.

6. Piller Press :

The above illustration is of pillar press. It’s a hydraulic press with four pillars at the bottom. The ram is supported and guided by the pillars.

At Rajesh machine tools we sell all kinds of Power Press machines be it H-type or any C-type frame machines. We provide you with machines with the best quality as you need to add for your workshop.

Power presses are a common type of machine tools. They can be a great benefit in many different industries, including metalworking and woodworking. Safety is an important concern when operating these machines. A good way to protect your staff is to install mechanical interlock guards or fixed guards.

Hydraulic Press Machine

Hydraulic press machine tools are used to form a variety of work pieces. They are designed to bend, draw, punch, and coin work pieces. Each tool has its own special configuration that allows the user to control the amount of force applied to different pieces and the amount of time it takes to complete each operation. Hydraulic presses can also be customized to perform various operations at different stages. Customization options include the shape of the die and the type of hydraulic fluid used to press the workpiece. Depending on the desired results, hydraulic presses can be customized for any size or shape of the workpiece.

Hydraulic press machine tools can produce high-quality components, assemblies, and parts. They are used in many industries. Hydraulic press machine tools can complete many large-scale processing tasks, including metal forging. These machines can reach up to ten thousand tons of pressure, and are commonly used for pressing materials together. They can also bend and straighten metal. Hydraulic technology has a history dating back thousands of years. Hydraulic technology is based on the principles of fluid flow and control. Joseph Brahma developed the first hydraulic press in the 18th century.

The increasing production of electric vehicles in the United States and elsewhere is increasing the need for more efficient metal processing equipment. Hydraulic presses are an ideal tool for shaping metal in the automotive industry. They can significantly increase the speed of production.

Hydraulic Press Brake Machine

Press brakes can be used to cut and bend metal parts into a variety of shapes. They work by applying force to a metal piece as it passes through the press. There are two types of press brakes: straight and offset. A straight type of press brake can be used for thicker materials.

The bending operation is controlled by a pedal. There is also an emergency switch. The clamps that are used in hydraulic press brakes include normal clamps and fast clamping tools that allow quick changes to the top punch. Safety is another concern when working with hydraulic press brakes, which come with steel fences and safety devices to prevent worker injuries.

A hydraulic press brake works like a pump that exerts pressure on a small cross-sectional area. This results in high mechanical force. Unlike flywheel-driven presses, hydraulic presses use little energy and are safe. The hydraulic fluid is transferred to the larger piston, which then applies more force to the material.

The structure of a hydraulic press brake consists of a frame and two upright plates with supporting bodies. It also has an oil tank that enables it to provide maximum fluid pressure while bending the material. The frame is made of metal and is connected to the fuel tank. The uprights have welded connections with the fuel tank to enhance the rigidity of the machine and increase its heat dissipation area. It also features a wedge-shaped crowning that ensures greater bending accuracy.

Final Thoughts

Hydraulic Press machine tools offer a number of benefits over conventional pressing machine tools. In addition to their accuracy, these presses are designed to operate cleanly and minimize operating costs. Clean operation eliminates the need for pneumatic equipment and reduces the need for maintenance personnel.

The hydraulic press brake is a powerful machine tool that can be used in many applications. It is designed for precise and repeatable bending of metal sheets and rods. It has many benefits, including accurate bending and quick set-up. It can save the labour and time of the operator. Compared to a traditional press brake, this machine is able to produce the most precise bend angle and frame.
