Mild Steel Sheet Metal Press Brake- China Manufacturers Factory Suppliers

Press brake is a kind of general equipment for bending sheet. Press brake can press metal sheet into a certain geometric shape by using a simpler general mold. For sheets of different thicknesses, V-groove lower molds with different opening sizes should be selected. The required bending force can be obtained from the bending pressure gauge.

What are the characteristics of press brake?

1. The oil cylinders at both ends of the body of the press brake are arranged on both sides of the slider to directly drive the slider. A mechanical stop is arranged in the oil cylinder to control the bottom dead center position of the slider. The upward end position of the slider is adjusted by the stop beside the travel switch.

2. The bottom dead center of the slide block of the press brake and the end position of the back gauge stroke are shown by the corresponding rotation number table.

3. The torsion shaft of press brake is used to forcibly synchronize the two ends of the sliding block and can withstand a certain amount of eccentric load.

4. The upper part of the press brake is equipped with a precision compensation mechanism, which can make the workpiece obtain consistent bending accuracy over the entire length.

What are the specifications of press brake?

The accuracy of press brake is a factor that needs to be carefully considered. It is this factor that determines whether you need a CNC or manual press brake. If the press brake requires in the range of 1° and cannot be changed, you should choose CNC press brake. The repeatability of the slider of the is in the range of 0.002 inches with the deviation of 2 to 3°under the condition of using a suitable mold.

The wear of each mold must be checked by measuring the length from the front end of the punch to the shoulder and the length between the shoulder of the die. The deviation per foot should be around 0.001 inches and the total length deviation should not be greater than 0.005 inches.

When free bending is adopted, the bending radius of press brake is 0.156 times of the opening distance of the die. The opening distance of the die should be 8 times the thickness of the metal material. If the bending radius is less than the thickness of the material, a punch that a radius at the front end is smaller than the thickness of the material must be used.

What is the future trend of press brake?

The press brake is a machine that can bend thin plates. Traditional processing methods in the metal sheet workshop include plate shearing, punching and bending. A large number of molds are needed. Adapting to modern metal sheet processing, press brake come into being, reducing production costs and improving processing technology.

With the development of technology, the modern production mode puts forward higher requirements for the production equipment. In the past, the press brake had to bend the entire batch of workpieces when performing multi-pass bending processing, which required continuous work of refueling. However, the stopper and the slider stroke of press brake can be controlled, which can continuously bend batches of workpieces in multiple passes. The press brake ensures that the workpieces have high forming accuracy and high degree of identity, which can greatly improve production efficiency and have a promising development prospect.

What is the difference between shearing machine and laser cutting machine?

Laser cutting machine is a piece of blanking equipment, which can cut boards of any shape, including straight, line and curve, holes and complex geometric figures. The laser cutting machine uses a focused high-power density laser beam to irradiate the workpiece to quickly melt, vaporize, ablate or reach the ignition point of the irradiated material. At the same time, the molten material is blown away by the coaxial high-speed airflow of the beam to cut workpiece. The incision of laser cutting machine is high but small without burrs. The cutting speed is based on the thickness of the steel and the power of the laser.

Shearing machine is a straight-line machine, which is mainly used to cut the straight edge of various sizes of metal plates. Although shearing machines are also blanking equipment, they perform simple shape cutting. Shearing machine is widely used in various industrial sectors such as steel rolling, automobiles, ships, tractors, bridges, airplanes, electrical appliances, instruments, boilers, and pressure vessels. The steel plate cut by the shearing machine has low degree, large cut and high roughness with burrs at a slow cutting speed. The cutting quality decreases more according to the thickness of the material.

What is the difference between guillotine and swing-type plate shearing machine?

The guillotine shearing machine is used in industries such as automobiles, tractors, rolling stock, ships, motors, and instruments. It is also suitable for stretching work of various high-strength alloy plates. The guillotine shearing machine adopts an integral welded-frame structure and has vibration treatment so that is has good rigidity, high precision and good precision retention. A three-point supporting shaft rolling guide rail is adopted that the upper tool holder rolls between the rolling guide rails without gap. The lifespan is determined by turning the hand wheel. The movable blade base and the four-edged long blade are convenient to adjust the uniformity of the blade gap, improving the cutting quality and extending the lifespan. The guillotine shearing machine uses tandem cylinder synchronization system with even force. By adjusting the flow rate of the tandem cylinders, the shearing angle can be easily to meet the needs of different shear plate thicknesses.

The swing-type plate shearing machine is used in the stretching, bending, extrusion, forming and other processes of metal sheets in the power industry and aviation industries. Compared with guillotine shearing machine, swing-type plate shearing machine mostly adopts oblique-blade, which is widely used due to simple structure, low failure rate, and high efficiency. As the tool holder rotates, the shearing angle and gap will change.

Which shearing machine can be viewed as high quality?

Relying on the guide rail, the shearing machine can realize intelligent movement. The cutting length and thickness are not limited by the size of the shearing machine. Even the guide rail can be lengthened as needed.

The shearing machine replaces manual feeding and adopts heavy-duty robots, which can load 5 tons at a time. It saves manpower and effectively avoids safety accidents.

The shearing machine has zero loss during the cutting process. The feeding platform can automatically flip the steel plate. In addition to eliminating manual operations, it also avoids the material waste caused by the long steel plate. During the operation, no pollutants are generated.
