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.

 

What is the parameter of shearing machine?

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.

How does CNC press brake work?

A CNC press brake works quite similarly to a hydraulic press brake. However, the difference is that CNC press brake is controlled by slider stroke and backgauge. All you have to do is input the number of pieces that require bending along with the bending angle, getting the job done with accuracy.

CNC press brake has a ram fitted with a punch that forces the material being worked into a die. The material is formed into an angle corresponding to the angle of the die or the depth the punch forces it into the die.

CNC press brakes can be pre-programmed to bend the sheet metal through many various bends completing one part at a time. It uses a V blade to push on the sheet metal with pressure against a die.

How to calibrate CNC press brake?

The CNC press brake adopts electromagnetic force clamping so that the pressing plate can be made into a variety of workpiece with side walls. The operation is simple.

Metrology personnel required to calibrate CNC press brake need to open the cover of the saw that the optical components can be adjusted on the worktable, the spindle and the independent tripod. The time that spatial calibration process needs depends on the size of the CNC press brake. If the part is within the tolerance range by the three-coordinate surveying and mapping machine, the spatial calibration is not so necessary.

The trajectory of the calibrated CNC press brake is not a straight line but lateral movement. Traditional correlators cannot do this, except for the single-aperture laser correlation instrument.

When testing a CNC press brake, use a moderate probe to measure the proportion of the drawing part. The specified spatial error can be listed as an error table or offset table. The software can correct the coordinates of the probe.

Why is shearing machine widely used?

The shearing machine plays a role in fast cutting for some panels that need to be processed. The traditional cutting wood is more often used by the see-saw method, which has slow speed and makes people tired. The saw blade is very easy to wear and break. However, the use of shearing machine gives a feeling of high efficiency, convenience and the high quality. Because the shearing machine has two blades merged into one joint, which can be adjusted, it can be cut at any angle, even if the plate is bent and deformed.

What is the structure of shearing machine?

The main structure of the shearing machine is generally composed of the body, the transmission system, the knife holder, the presser, the front stopper, the rear stopper, the supporting device, the blade gap adjustment device, the light alignment device, the lubrication device, electrical control devices and other components.

The shearing machine is welded by steel plate, which has good rigidity. The two cylinders are fixed on the left and right columns. The auxiliary tool holder is provided on the working table to facilitate the micro adjustment of the lower tool holder. There is also a feeding ball on the working table of shearing machine.

The upper tool holder is a steel plate welded structure. It uses the eccentric sleeve as the fulcrum to swing back and forth under the drive of the left and right oil cylinders and the accumulator return cylinder to complete the shearing. The vertical supporting surface of the blades of shearing machine forms an arc-shaped curve to ensure the consistency of the gap between the upper blades during the cutting process.

The material pressing device is composed of several material pressing oil cylinders installed on the front supporting surface of the frame. The head presses down after overcoming the tension of the relay spring to compress the sheet material. It resets by the pulling force of the tension spring.

How does shearing machine work?

The shearing machine should be able to meet requirements of the straight and parallel shearing surface of the sheared sheet. Shearing machine should minimize the distortion of the sheet to obtain high-quality workpieces. The upper blade of the shearing machine is fixed on the knife holder, while the lower blade is fixed on the workbench. A holding ball is installed on the workbench so that the sheet material will not be scratched when performing. The back gauge is used for positioning the plate that the position can be adjusted by the motor. The pressing cylinder is used to compress the sheet to prevent the sheet from moving during shearing. The guardrail is a safety device to prevent work-related accidents. The returning generally relies on nitrogen, which is fast and has little impact.

The movement of the shearing machine is that the belt on the motor transmits the torque to the large pulley shaft. The large pulley shaft has a small gear at the other end. The power is transmitted from the small gear to the large gear on the shearing shaft. The large gear shaft is equipped with a clutch mechanism. When the shearing machine is operated, the large gear drives the shearing shaft. The eccentric wheel on the shearing shaft drives the upper knife holder to move up and down linearly through the connecting rod to shear.

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.

How to use shearing machine?

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.

What should be paid attention to when using shearing machine?

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.
