How many types of shearing machines are there?

Dedicated shearing machine is always combined with other equipment to complete special purposes. Cold-formed line shearing machine is a special shearing machine configured on production lines. Steel-structure line shearing machine is mostly for angle steel and H-beam automatic production lines to complete the shearing process. Plate and line shearing machine is a high-speed shearing machine designed to meet the high-speed cutting requirements of the production line for the plate uncoiling and leveling line. Hydraulic high-speed shearing machine is available for thick plate line, while the thin plate line is equipped with pneumatic shearing machine.

The upper and lower blades of oblique-blade shearing machine form an angle. The upper blades are inclined, whose inclination angle is from 1° to 6°. The shearing force of this type shearing machine is smaller than that of the flat-blade one. It has a wide range of applications.

Flat-blade shearing machine has good quality and small distortion. But the shearing force and energy consumption are large. There are more mechanical transmissions. The upper and lower blades of the shearing machine are parallel to each other, which are used in hot-cutting of blooms and slabs in rolling mills.

Combined-punching shearing machine can do the cutting of the plate and the profile, which is mostly used in the blanking process. Sheet-bending shearing machine contains two processes that shearing and bending can be performed on the same machine.

How to choose shearing machine?

Determine the specifications and parameters of the shearing machine according to your own demands. You should consider the required range of the m aterial thickness of the sheared material. You can contact the manufacturer for recommendations if you are not sure.

Confirm which manufacturers produce the shearing machine to be purchased. The model produced by different manufacturers is different. Therefore, users should pay special attention to choosing the best one. Choose some manufacturers for comparison, such as the quality and the after-sales service.

It is better to pay attention to the overall condition of the shearing machine manufacturer. It is recommended to visit the factory. After removing the highest and lowest prices, choose a trustworthy manufacturer to get better price and performance ratio.

Why we use press brake?

Press brake uses the electro-hydraulic servo system to control the two-cylinder synchronization. Press brake cooperates with the international standard grating ruler to form a fully closed-loop control. The synchronization has high accuracy and high level of the bending and repeat accuracy.

Press brake can be equipped with hydraulic upper mold automatic clamp, quick clamp, or slot type lower mold to reduce the labor and improve efficiency.

Press brake is equipped with high-quality linear guides and ball screws to ensure the accuracy.

Press brake has flexible operation mode, not only solving the processing of ultra-long plates by dual-machine linkage, but also processing short parts by single-machine operation. Press brake improves the utilization rate and reduces energy consumption.

The frame of press brake is welded with steel, ensuring high rigidity and machining accuracy.

How does press brake work?

To avoid cracks on the radius, it is essential that the press brake is carried out orthogonally to the rolling direction.

The press brakes are controlled by mechanical systems, a crank connecting rod system, and hydraulic pistons. Press brake can be operated by manually or computer, called CNC press brake.

The metal sheet is deformed by a bending force of press brake which necessarily exceeds the limit that the elasticity of the material imposes.

Also, the press brakes are equipped with a punch mounted on the movable part. This part of press brake is composed of a die and a blank holder piston with the same functions and characteristics of a mold for a press.

Press brakes contain a work table, a clamping plate, and supporters. The worktable consists of a base and a pressure plate, which is attached to the supporters. As working with a press brake, adjust the bending angle and dimensions continually.

What are the uses of press brake?

The forming of press brake greatly depends on operator’s skill. Therefore, varying levels of quality and productivity are to be achieved by two different operators.

Press brake is available for bending sheet metal. The sheet metal will play a important role in the manufacturing industry. These sheet metals processed by press brake are used in home appliances, vehicles, heavy equipment.

Before the right sheet metals are formed, press brakes should first consider the right die design to produce the right sheet metal. Press brakes are used in different forming works with the right die design like V dies, rotary bending dies, acute angle dies, and radius dies.

In a mechanical press brake, power is added to a flywheel with an electric motor. A clutch matches the flywheel to power a crank mechanism moving vertically. Accuracy and speed are two advantages of the mechanical press brake. Hydraulic press brake operates by means of two synchronized hydraulic cylinders on the C-frames moving the upper beam.

What are the types of laser cutting machines?

In terms of cutting material types, there are two types of laser cutting machines: metal and non-metal laser cutting machine. A metal laser cutting machine is used when metal materials are needed, while a non-metal one is to cut non-metal materials.

Classified by laser types, the laser cutting machines can be divided into three types: fiber, CO₂ gas and YAG. Now, the mainstream type of laser cutting machine in the domestic market is fiber laser cutting machine.

According to the laser output power, laser cutting machines involve high-power, medium-power and low-power laser cutting machine. In the industrial field, high-power ones are needed, while the medium-power ones are main in the laser engraving field.

As far as the cutting board size, the laser cutting machines contain standard-format and large-format ones. The cutting length of the large-format laser cutting machine in the X-axis direction is more than 8000mm, and the cutting width in the Y-axis direction is more than 2500mm. For the standard-format one, it is generally about 3000mm multiply1500mm and 4000mm multiply 2000mm.

The cutting plates have flat plates and three-dimensional plates. Flat plates are cut by a flat laser cutting machine, while three-dimensional plates can be cut by a three-dimensional five-axis laser cutting machine.

How to choose laser cutting machine?

Make clear processing demands, such as processing material type, size, and accuracy tolerance. It helps determine which type of CNC laser cutting machine you need. For metals, you may look for a metal or fiber laser cutting machine.

Choose the right laser cutting machine manufacturer. It matters a lot concerning the quality. Good manufacturers provide high-quality machine with a complete quality assurance system and after-sales service system.

Choose the configuration. You can negotiate the configurations and specifications with the manufacturer. All the configurations shall be based on specific processing requirements. It may include lasers, laser heads, servo motors, guide rails, and water coolers. If you are not sure about the specifications, you can introduce your requirements that the manufacturers will recommend the suitable one.

How to use laser cutting machine?

Decide what material to cut or engrave. Laser cutting machine can cut and engrave wood, plastic, cardboard, foam, fabric, and thin sheets of metal. Any material containing chlorine cannot be used due to the toxic fumes.

Choose an image, such as a photo, a computer drawing, and computer text. Make sure the image has plenty of contrast without many shadows. Upload the image into software that is compatible with the laser cutting machine. Set the dimensions of the image to match the size of the material. Optimize the image.

Place the material in the center of the laser cutting machine. Press any key to let the laser test the dimensions across the mat. If your material has a bend, place a weighty metal rod to hold it down.

Clean the lens with rubbing alcohol. Set the lens height. Most laser cutting machine will have an automatic lens height sensor or button. If not, you will need to adjust the height manually.

Turn on the fume extractor to suck all the fumes and dust from the material out of the laser cutting machine

In the material settings, select what kind of material you are using. This will affect the settings of the laser. Select what type of cuts you are making. Press print.
