CNC Hydraulic Sheet Metal Press Brake Bending & Shearing Machine

500 Ton press brake   is a primary size in big tonnage machine. Under this tonnage, the standard length of work table start from 4000mm to 8000mm. If clients have special requirements, some customized size can be redesigned ------ this is the advantage and skill service of GLDMA.   Application fields of this size include bridge construction, public facilities producing, big storage racks manufacturing, also some small boat processing. 500T/8000mm can bend max 8mm/8000mm size, and 500T/4000mm can reach max 15mm/4000mm bending capability. We usually suggest client to choose CNC type on large tonnage machine, to ensure the bending effect and quality. The max opening height (daylight) can reach 600mm, and throat depth is 500mm. These parameters are both decided by the pressure and structure designed. During the producing of  large size plate bending machine , most important is the whole structure processing. GLDMA brought four big floor-type milling/boring facilities thi...

The 30 ton press brake is a wise choice for small enterprise. As the development of world, more and more country have some small enterprise who take part in industry area. As metal play an important role in so many different industries, press brake also become more and more important. So for those small enterprises, we GLDMA design 30 ton press brake. Economichyd The  small size press brake  like 30 ton will not be a heavy burden to small enterprise. It can be a best choice when some company want to enter the metal process field. Besides, it will bring you profit soon if you have enough order. Quality Compare to big machine,  30 ton press brake  still have same high quality. The design of this servo press brake compliance with EU international standards. The fuselage eliminates internal stress by annealing and ensures higher strength and precision. All these  MB8 series  steel sheet bending machines  are designed by SOLID WORKS 3D progra...

Business, especially when they need  large  pieces of metal bent, will look into getting large, single press brakes to handle the workload. However, tandem press brakes can handle similar length requirements and will still provide your company with capability you might lose with large press brakes. Tandem press brakes can:  Run together, singly, or at the same time independently;  Be set up with two different sets of tooling to increase efficiently in multi-stage bending;  Bend small pieces of metal alone or large pieces together. When tandem bending machine used in the process, the cylinder which on both sides can synchronize its imports of electro-hydraulic. So to the relevant structure of grating ruler can form the unique mechanical closed loop.During the working process it will has certain accuracy at the same time, and the slide block in the process of running are more accurate. What is more, its automatic in adopting this hydraulic shape co...

The operation standards of  hydraulic press brake machine  are very necessary and reasonable for those who just start to use it to learn and read. Operating hydraulic bending machine according to the standards can greatly prolong the life of the machine and ensure the safety of the operator at the same time. 1. The operator must read the instructions in detail before using the bending machine to acquaint with and grasp the structure, performance and adjustment method of the bending machine. 2. If there are multi-operators operating the machine, confirm that there is no unsafe factor before stepping down the foot switch. 3. The clearance between the upper and lower molds must be adjusted evenly. When working, no tools can be placed on the lower mold and the worktable, and defects such as welding scarring cannot be found on the surface of the workpiece. 4. Always keep the bending machine clean. When using it, attention should be paid to the conditions of all parts of the bending...

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 ...

Press brake bending machine is suitable for large steel structure parts, tower, lamp pole, high lamp pole, car girder, automobile truck container and other related industries. The essence of  press brake bending machine  is to bend the hardware thin plate, and the bending process is closely related to the press brake bending tool.The press brake machine tool consists of a bracket, a worktable, and a clamping plate. Through the power of the coils, the gravity of the pressure plate is generated, so as to complete the clamping of the thin plate between the pressure plate and the base.Because of the method of electromagnetic force holding, the pressure plate is made according to the specific requirements of the workpiece, which is easy to operate and can be processed with the workpiece with side-wall. At present, there are different types of press brake bending machine in the market, such as electric hydraulic servo press brake bending machine, torsion sy...

At present, the operating system of CNC press brake in domestic market mainly includes Delem DA52 and Delem DA65W.The price of the two operating systems, Delem DA65W, is higher than that of Delem DA52, and the price difference is tens of thousands. After knowing the price of these two operating systems, I will give you a brief analysis of the differences between the two operating systems and how to choose them. First of all, we must know the purpose of buying the  CNC press brake  is to process products and which products will be processed later. After all, buying equipment is a capital investment for the company, which is crucial for the future development of the enterprise. If our products are more complex, small, and frequently changing product types, I feel that the Delem DA65W will be better. But a single large enterprise, Delem DA52, is basically enough. The CNC press brake is compared with ordinary press brake, and the precision and eff...

The common malfunction of electric- hydraulic press brake  and solutions 1. Slide can't move down quickly  The poppet valve is not connected and the spool is stuck  The spool of the directional valve which controls filling valve is stuck, can't be reset  The orifice of the filling valve is blocked  The proportional valve is abnormal  The mechanical part is too tight 2. There is large synchronization error between two cylinders when slider quick moves down  There is large friction difference between the two guide rails  There is large friction difference between the two cylinders  The connection between one cylinder and slider is skew, radial force  Check whether the damping in the filling valve control port which is on synchronous block is blocked  Check whether the filling valve is stuck  Check whether the cylinder, slider is too tight  The proportional valve is abnormal 3.The system does not build ...

Electro-hydraulic Servo Press Brake , most clients will feel confused of this name. What is that? Actually it's a kind of totally CNC press brake machine. This bending machine consists of machine rack frame, slider, work table, cylinders, hydraulic proportional servo system, position detection system, CNC system and electrical control system and other components. It's a kind of high precision, high efficiency sheet metal processing equipment. The slider up and down movement is driven by the left and right two cylinders. Relying on the mold respectively on slider and work table, the sheet metal can be bent into different angles or cross-sectional shape. During the movement of the slider, two grating scales mounted on each side of the machine detect the position of the slider at both ends in real time.  On the one hand, comparing the two values, according to controlling the proportion of servo to correct bias timely, in order to maintain the slider parallel. On the other hand...
