Bending is a processing technique of deformation and forming after shaping. It is performed industrially with press brakes. Press brake can perform rectilinear and parallel folds on pieces of medium-large dimension. The minimum radius relies on the thickness and type of material to be bent.
Why we use press brake?
How does press brake work?
What are the uses of 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.
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.
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.

Shearing machine is a kind of equipment that can cut the metal sheet, automatically count, and send to the next process by the feeding car according to the processing requirements. It is widely used in machining. Shearing machines can cut steel plates of various thicknesses.
What are the structural characteristics of shearing machine?
How to use shearing machine?
What should be paid attention to when using shearing machine?
The frame of shearing machine adopts steel structure that has left and right vertical plates. The workbench and the blanking plate are welded into a whole structure. After welding, the internal stress is eliminated by tempering so that the shearing machine has high rigidity and stability.
The tool holder of shearing machine adopts a steel structure. Under the thrust of the cylinders on both sides, it can swing around the fixed pin to complete the shearing action without the need for a guide rail system. At the end, under the action of the return cylinder, the tool holder returns quickly and automatically. Shearing machine has a mechanism for quickly adjusting the blade gap.
The backgauge of shearing machine is installed on the tool holder and swings with it. The adjustment of the backgauge distance is driven by a motor, which is transmitted respectively to the left and right screw rods through a transmission shaft and a pair of sprocket pairs, driving the backgauge to move back and forth along the guide rod. There are two buttons to perform the forward and backward coarse adjustment. There is an adjusting hand wheel on the button box to fine-tune the stroke and positioning. A mechanical display meter displays the distance of the backgauge.
The hydraulic system of shearing machine is installed on the end face of the oil tank, which is fixed on the frame beam. It is easy to clean and disassemble. The system pressure is supplied by the oil pump.
When the material to be cut is fed, it is automatically transported in the right place of shearing machine by the motor.
The cut size of the sheet is fixed. Shearing machine controls the position to ensure the accurate cut size.
The shearing machine presses and cuts the sheet material after the material is positioned. The main motor drives the presser and the cutting tool.
The stopper allows the knife to move to a certain long position. Rotary unloading of sheet bracket.
The operation of the feeding cart includes automatic return after unloading.
The size setting, automatic counting and the number of sheets should be pre-set. The corresponding position signal detection switch must be set in the system. The installation positions of the various detection components of the shearing machine, the presser compression travel switch, the stopper fixed-length switch, the trolley status information switch, the trolley in-position switch, and the unloading in-position switch should be checked.
Shearing machine needs professors to be responsible and operate. The operator should be familiar with the structure and performance.
Shearing machine is used to cut metal plates with a thickness of 1 to 12mm. The cut sheet is based on mild steel with a tensile strength of 450N/mm² and an elongation of 25%. If you need to cut the stainless-steel plate, the cutting thickness is 1 to 6mm.
Before starting the shearing machine, check whether all parts are normal. All sundries and tools should not be stacked on the workbench.
The operator is not allowed to remove the protective fence. He must not put his hands between the upper and lower blades. The shearing machine needs to stop when picking up and cutting the workpiece to keep the movable parts at the rear of the shearing machine from injuring others.

The shearing machine is all steel welding mechanism. It has a good performance in reducing vibration stress, which has good rigidity and stability.
Shearing machine adopts advanced hydraulic integrated valve block in compact structure. It can reduce pipeline connection, improving system reliability and maintainability.
The series oil cylinder makes the shear angle not change during cutting. The main oil cylinder fixed on the wallboard moves downward to control shear movement. The nitrogen cylinder controls the returning. The hydraulic system is simplified and the operation is more stable.
Shearing machine uses hydraulic transmission, which has light weight, low noise, lightness, reliability, and overload performance.
Standard shearing machine is equipped with five stations and dual hydraulic workstations, which can work independently at the same time. The shearing machine does not need any horizontal adjustment.
Shearing machine uses CNC control system to increase automatic punching and cutting efficiency.
The frame of shearing machine is welded by the whole machine. After high-temperature quenching treatment, it has high rigidity and high strength.
The major parameters in shearing machine are the shape of the punch and die, the speed of punching, lubrication, and the clearance between the punch and the die.
The clearance between the punch and the die is a major factor in determining the shape and the quality of the shearing machine. As the clearance increases, the zone of deformation becomes larger and the sheared edge becomes rougher. The sheet tends to be pulled into the clearance region. The edges of the sheared zone become rougher. Secondary operations may be required to make smoother, which will increase the production cost.
Edge quality can be improved with the increasing speed of punching of shearing machine. Sheared edges can undergo severe cold working due to the high shear strains. The hardness of the edges will reduce the ductility of the edges and adversely affect the formability of the sheet during bending and stretching.
