CNC Hydraulic Sheet Metal Press Brake Bending & Shearing Machine

In the past few years, the metal plate processing industry has achieved many technological advances in machine tools and moulds. Now the machine tools can be used to punch, cut and bend with the speed and precision that are beyond the expectation. However, no matter how advanced the new technology is, there are some bottlenecks in the bending workshop or section of the metal plate processing, which even the most advanced factories cannot be avoided. Although these problems cannot be attributed to one reason, the metal processing plant can achieve improvements in many ways, which can help to shorten the lengthy preparation time, improve the efficiency and enhance the comprehensive production capacity. Execute SOP on repeated work Metal plate processing plants now are facing a difficult problem: most of the processing tasks are small, tolerable, and the adjustment of each flight in every 15 times is common, and for many factories, the adjustment time is far beyond the number. Technicians...

The nozzle of  laser cutting machine  can assist the rapid gas ejection. It can effectively prevent impurities such as melted up to rebound, and then protect the focusing lens. At the same time, it can control the area and size of gas diffusion, thus further affect the cutting quality of laser cutting machine. At the same time, the size of the nozzle is various according to the thickness of the cutting material. 1. When cutting thin plates (below 3mm).  The nozzle with diameter of 1mm diameter will be relatively fine, and the nozzle with diameter of 1.5mm will be relatively thick, and the corner will be easier to contain stains. 2. When cutting thick plates (above 3mm).  The nozzle of the diameter of 1mm is not very stable. Because at this time, the power of cutting is high, the relative heat dissipation time is longer, and the relative cutting time also increases, the nozzle gas diffusion area with the diameter of 1mm diameter is small, so it is not very stable, but...

The simplest outline of  metal plate processing  is to process different materials of metals. In the process of metal plate processing, there is a certain requirement for metal materials. Not only the integrity of the metal plate is required, but also the metal appearance, such as whether the metal is over oxidation or not, while in the process of the metal plate, metals are not allowed to be oxidized. In addition, the thickness of the metal is required to exceed the thickness of treated goods; but in reality, there is hardly any metal that has not been oxidized, so how do we need to deal with the oxidized metal? Stainless steel in processing operations is usually treated by rolling, welding, or heating through the artificial surface, to produce the black oxide coating. This kind of gray black oxide coating is strong and contains two kinds components of EO4, NiCr2O4 and NiF. In the past, it was basically eliminated by using hydrofluoric acid and nitric acid for stro...

We must have a comprehensive understanding of bending machine for better usage, pay attention not only to the machine itself but also the matching bending die. The bending die of the bending machine generally adopts the upward forming method, which needn’t the upper plate and the upper pad. Only when the mold is large, for example, when the height of the die is above 350mm, it will use the upper plate. If the components are small, the hole can be dug directly on the lower die of the  press brake  machines and then bent it by inserting the bending part. When the bending edge is long with the shape bent, the lower mould forming of the lower bending machine is set with inserts, milling the slot on the lower splint and the pinned, then the thickness of the lower splint is 25, the milling groove depth is 7, the insert width is not less than 30. When there is a longer internal bending, it can be referenced by the inner bending die structure. There are also factors to be consid...

The application of the  press brake machine  is indispensable in current industrial production, because it is the main operating equipment for the bending of the plate, only after this process has been down can the workpiece enter into the next step. The press brake machine can make use of the pressure the pressure plate puts on the workbench, and find the linear relationship between the design parameters and the deformation through the traditional calculation, so as to realize the bending of the materials. For different types of press brake machines, the requirements of the sheet material and bending shape are different. So, before buying a press brake machine, it is necessary to determine what kind of parts you want to produce, and what kind of materials you will use, then using the machine to bend the sheet into the shapes you desire. Be careful when operating the press brake machine. When bending the plate, the slider will occur elastic deformation, which seriously affec...

In order to ensure the precision and quality of the bending steel plates, it is considered that the engineer not only should choose suitable and high-quality press brake machine but also should maintain a horizontal condition of the steel plates while bending them. The engineer must be in strict accordance with the part drawing or the diameter size which is provided by the lofting to line the edges and bend the steel plates. And he must select the appropriate models for the press brake machine according to their size of bending diameter. If the  press brake machine  works for a batch of steel plates, it must try to bend one of these to test its bending quality. The qualified bending steels’ quality of the two sides edges should be mellow and smooth, and the edges’ width and size should meet the requirement of the requirements for steel pipes, etc. If the abnormal situation appears, the engineer need to adjust the press brake machine or the models or choose other ways to solve ...

As a hydraulic device, the interior of the  Hydraulic press brake bending machine  is equipped with the corresponding hydraulic oil pump, which has many types, so what kind of oil pump is often applied in a hydraulic bending machine among gear pump, screw pump, vane pump, plunger pump and so on? The gear pump used in a hydraulic bending machine is simple in structure, good in technology, small in volume, light in weight, easy to maintain and long service life. However, the working pressure is low, while the flow pulsation and pressure pulsation are large, so the volumetric efficiency of hydraulic bending machine will obviously decrease under high pressure without end compensation. The screw pump used in a hydraulic bending machine is also a kind of gear pump, which is simple in structure and light in weight. Flow and pressure pulsations are small, conveying even, without turbulence and stirring, and rarely bubbles produced. The work is reliable with small noise and so on,...

Bending machine is able to do conventional plate bending processing, based on that, it can also complete much special processing, such as reaming processing after bending, groove treatment before bending, cutting holes or cutting lines alongside the bending line, using repair processing to make it to the design dimension at the edge of the hole after bending. When  press brake bending machine  doing reaming processing after bending, only one or a few pixels hole to the distance of the bending lines is less than the minimum spacing. When the need for product appearance is strict, in order to avoid material stripping when bending, you can treat the pixel with shrinkage, but there are many procedures to do and the efficiency is low. In actual design, because of the need for structural design, the processing factory usually adopts the groove treatment before bending because the actual distance is smaller than the above-mentioned distance. Since the numerical control bending machi...

The  laser cutting machine 's nozzle can help emit gas quickly, which can effectively prevent the sundries and other debris from rebounding upwards, thereby protecting the focusing lens. At the same time it can control the gas diffusion area and size, which in turn will affect the cutting quality of the laser cutting machine. In addition, the nozzle size varies the thickness of the material being cut. 1.In cutting thin plates (below 3mm), Φ1mm aperture nozzle will be relatively fine, while Φ1.5mm aperture nozzle will be relatively thick, and the corner will be more likely to contain stains. 2. In cutting thick plate (above 3mm), the Φ1mm aperture nozzle is not stable when used. Because the cutting power is higher at the moment, the relative heat dissipation time is longer and the relative cutting time is also increased. With a Φ1 mm aperture nozzle, the gas diffusion area of the nozzle is small, so it is not stable, but basically can be used. The Φ1.5mm aperture nozzle has a lar...

The laser cutting technology is more cost-efficient than the traditional processing technology and the laser beams are all in the shape of points, therefore it has great flexibility in two-dimensional plane processing. In the laser cutting machine processing, only the cutting head moves, while the workpiece is stationary. There is no need to set up micro-connections, helping the laser in the cutting process is relatively simple. Its computer CAM system does not require the production of a single part machining process. It is only necessary to optimize the layout results and the cutting route, and then start the laser to process it. However, in the multi-functional machine, it is necessary to set the mold, preset the laser cutting route, and set the connection site, and then the next step can be taken. In comparison, the preparation time of the laser cutting process is greatly reduced compared with the laser cutting machine. In practical use, when the laminating machine is processing...
