What are the common faults of press brake?

Press brake makes poor surface roughness of the workpiece. The tool tip of the press brake is damaged that is not sharp. The press brake resonates leading to the unstable placement. The press brake has a crawling phenomenon, resulting in poor processing technology.

The workpiece produces taper-size head. The level of the press brake is not adjusted properly that one side is high and the other is low, resulting in uneven placement. When turning the long shaft, the material fed is too hard to be cut deeper. The tailstock thimble and the spindles are not concentric.

The size of each workpiece is inconsistent. The carriage of the press brake runs at high speed for a long time, resulting in the wear of the screw and bearing. The repeated positioning accuracy of the tool holder produces deviations during long-term use. The carriage can accurately return to the starting point of processing every time, but the size of the processed workpiece is still changed. It is generally caused by the main shaft, caused by the high-speed rotation to wear.

How to avoid electric leakage when the press brake is working?

For the press brake, it is inevitable that there will be leakage in the working process. If the leakage is not handled in time, it will damage to safety.

In order to avoid the occurrence of electric leakage when the press brake is working, the press brake must be equipped with a leakage protector, it is a current-driven leakage maintenance device, which has a good effect on the protection of the press brake.

When operating the press brake, if the insulation of the electrical installation equipment is damaged, the cover will be charged. The correct grounding and zeroing work must be done. The electrical installation of the press brake should be maintained with high-voltage grounding to reduce the risk of electric shock.

The wiring operation of the press brake is also very simple. It is enough to connect the metal shell and the common maintenance neutral line firmly. Lead out from the neutral line on the power side of the leakage maintainer. Under the protection of its maintainer, the press brake can maintain a good and stable situation.

Why there are errors when using the press brake?

The outer circle of the bend is a cone. The connection between the front and rear centers is not coaxial with the spindle axis, which is caused by the wrong position of the tailstock center of the press brake.

The workpiece vibrates when bending. It may be that the tailstock sleeve of the press brake extends too long or the support of the workpiece is too loose. The mold is not sharp enough or the arc is too large. The bearing clearance of the rotary center is large. The clearance of the medium and small sliding plates is too large.

The mold does not meet the requirements. The mold and the main shaft axis of press brake are not on the same axis. The circular runout caused by the wear of the bearing. The center hole of the workpiece is not cleaned or is fuzzed. The center hole does not work because the lever in the center of the mold touches the end face of the chuck.

What are the failures of laser cutting machine?

Laser cutting machine has become an indispensable tool for metal sheet processing enterprises. However, when using laser cutting machine for processing, we encounter some problems, like the large gap of steel plate and the reduced accuracy of the processed components.

A lot of heat will be generated, which may deform the surface of the thin plate and the processed workpiece.

The focus of the laser cutting machine and the surface of the processed object change, causing the large cutting gap or inaccurate processing.

An error will occur due to the incorrect position of the worktable. If the laser cutting machine is not installed firmly and the parts are worn for a long time, the worktable surface will be uneven. This imbalance will also cause problems between the thin steel plate and the laser focus, resulting in excessive cutting gaps or reduced processing accuracy.

What materials can be cut by laser cutting machine?

One of the biggest advantages of laser cutting machine is to cut a wide range of materials.

Laser cutting machine can cut all types of metals, ranging from mild steel to stainless and non-ferrous metals. More reflective metals like aluminum are more difficult to cut. The thickness of the metal can be up to 30mm. The maximum thickness depends on the laser cutting machine.

Different types of wood are suitable for cutting like plywood and MDF. However, be aware of oils or resin to avoid fire.

Paper and cardboard are also suitable for laser cutting machine, where the popular wedding invitations are made.

Plastics also leave a great finish when using laser cutting machine that the edges are melted in a polished way.

POM is a highly utilized plastic in the engineering sector, finding usage in gears, guiding and sliding elements, medical instruments, and food packaging. It can also be cut by laser cutting machine.

Cutting glass is a seemingly impossible task because of its fragile and reflective properties. However, laser cutting machine can engrave glass.

How to maintain laser cutting machine?

Replace the circulating water once a week. Make sure that the laser tube is filled with circulating water before the laser cutting machine works. It is recommended to use pure water and keep the water temperature below 35°C.

Long-term use of the fan will accumulate a lot of solid dust, making the fan generate a lot of noise and not conducive to exhaust and deodorization. Disassemble the air inlet and outlet pipes on the fan. Remove the dust inside. Turn the fan upside down and pull the inner blades until they are clean.

It is recommended to clean lens before laser cutting machine works every day. There are 3 mirrors and 1 focusing mirror on the machine. The lens are easily stained with dust or other contaminants, which can cause laser loss or damage to the lens. Just rotate to wipe from the center to the edge with the lens wiping paper.

After the motion system has been working for a period of time, the screws and couplings at the motion connection will loosen, which will affect the smoothness of the mechanical motion. Observe whether there are abnormal noises or phenomena in the transmission components.

It is recommended to check whether the optical path is normal before each work.

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.

• How to choose V groover machines?

• How about the market situation of V groover machine?

What are the types of V groover machines?

The working table of vertical CNC V grooving machine is small and narrow. The planer is fixed in a straight-line position to the working table. Variable factors can be so well-controlled that the position accuracy is in the range of 0.02mm. When the vertical V groover machine is working, the holder part moves back and forth. Vertical V groover machines have many separate pressing plates and independent clamps. It can do both horizontal and vertical grooves. The surface is made of high-quality mold steel, which goes through overall heat treatment after a grinder refined.

The working table of horizontal CNC V grooving machine is larger and easier to work. The knife is facing a platform with 1.5 meters width and more than 4 meters length. The accuracy is lower. When the horizontal V groover machine is working, the gantry and the holder move back and forth together. Its energy consumption is more than 10 times than that of the vertical V groover machine. A horizontal V groover machine is available for large sheet metal. It cannot be able to horizontal gouging. The working table is welded by a common iron plate, causing spots on the processed products for long-term use.

How to choose V groover machines?

When choosing a V groover machine, considering the materials such as steel bars, concrete walls, and stones. Once they are encountered, you must choose a diamond blade. With high hardness, it is widely used for cutting marble, steel bars, stones and other super-hard materials.

The power of V groover machine is an important indicator. In fact, it does not mean the higher the power the better the V groover machine. In the ordinary grid lines, it cannot withstand the 4000W power at all. Three-phase power is required to achieve smooth operation.

The size of the V groover machine motor determines its power. The larger the size of the motor, the greater the power. The power can be obtained by measuring and comparing the diameter of the stator and the length of the rotor.

Groove depth should be measured by two dimensions: the distance from the center of the tool shaft to the tool cover and the height of the tool beyond the bottom of the V groover machine. The larger the distance, the larger the diameter of the blade that can be installed. The higher the distance, the deeper the groove. It is best to choose V groover machine with deeper and wider grooves.

Also, you should choose a V groove machine that can adjust the depth of slotting to meet different demands.

How about the market situation of V groover machine?

Chins will continue to support the development of CNC V grooving machine. During the Fourteenth Five-Year Plan period, we will continue to invest the CNC industry greatly to elevate the cultivation of core competitiveness, innovate independently, integrate quantitatively and build brand.

Numerical control processing is the trend of high-quality, high-precision, high-yield, and high-efficiency development in the V groover machine industry. The good development trend shows that the demand is still at a high level. Companies should seize the opportunity and strive to realize the transformation of V groover machine from low-end to high-end, from primary processing to high-precision manufacturing.
