Type and number of CNC Press Brake

The  cnc  press brake is generally divided into the torsion axis nc synchronous press brake and the electro-hydraulic servo  cnc press brake . Their main differences can be summarized as follows: 1. Guarantee that the structure of the two sides of the bending slide is different, and the press brake is connected with the rigid shaft of the two cylinder piston simultaneously, and the electro-hydraulic servo press brake is synchronized with the servo synchronization valve on both sides. 2. Different precision.The electro-hydraulic servo press brake is relatively synchronous with high accuracy, with real-time error feedback, and the flexural ability is strong.There is no error feedback in the torsional axis synchronous press brake, and the deflection of the bending block is poor. 3. The price is different.The numerical control system of twisting shaft synchronous press brake is different from that of electro-hydraulic servo press brake, and the price difference of system itself is

The Application Industry Brief of Press Brake Bending Machine

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 synchronouspress brake ben

Surface Treatment of Sheet Metal Processing

The decorative and protective effects of sheet metal processing on the surface of the product are recognized by many industries.In the sheet metal processing industry, the surface treatment methods commonly used are electroplating, spraying and other surface treatment methods. 1. Electroplating is divided into galvanized (color zinc, white zinc, blue zinc, black zinc), nickel plating, chromium plating, etc.; It is mainly to form a protective layer on the surface of the material to protect and decorate. 2, spray paint and powder, is the materials after pretreatment, spray gun, air sprayed coating to the metal workpiece surface, coating on the workpiece surface coating. After drying, play a protective role; 3. Other surface treatment methods: anodizing, chromate, drawing, sandblasting, oxidation, etc.; Attention! 1.

How to Select the Operating System for CNC Press Brake?

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 efficiency of the processed products

The Future Development Trend of CNC Press Brake Machine - Multilateral Press Brake Machine

In life, we often need to take the elevator, but you know, although many elevators are made by us, the machine tools that produce elevators are imported from abroad. One of the difficulty is that the press brake machine needs to be used in the production of elevators. Currently, the domestic equipment can only do the unilateral bending, which requires manual assistance when encountering the multilateral bending. Many people do not think that we often take the elevator in our lives, and many of the machine tools are imported. Take the elevator door as an example, the elevator door we see seems to be a plane, but actually, it's a "square box". The outside of the elevator has a door panel, and there is a door panel inside, which is hollowed-out in the middle.The elevator doors need to be folded into a "square box". It's like taking a piece of paper and folding it into a box.  Among them, folding this "square box" needs to use bending machin

Common Failure Analysis of CNC Hydraulic Bending Machine

Failure 1: no pressure on the hydraulic system Whether the electromagnetic coil of the proportional overflow valve is electric, and whether the proportional electromagnetic coil voltage meets the requirements, for the above reasons, please check the relevant electrical reasons. Check whether the cartridge valve is stuck or whether the main valve core is jammed, and the damping holes are blocked. If this is the above reason, please remove the overflow valve to clean and reload. Three-phase power supply phase, leading to motor reversal. Fault 2: the slide is fast and slow, and the time is too long Check whether the oil level of the oil tank is too low, and the filling port is not submerged.For the above reasons, the oil tank oil can be added to above 5mm above the filling mouth and the filling hole is completely submerged. Check whether the fast-forward speed is too fast, and the filling is insufficient.For the above reasons, the fast forward speed can be reduced by modify

The development trend of CNC bending machine

CNC press brake bending machine is a kind of machine which can be carried out on the thin plate bending , and the structure mainly includes the bracket, workbench and clamping plate. Workbench is on the scaffold, consisting of base and the clamp. The base is connected with the clamping plate through the hinge and the base is composed of shell, the coil and plate. Coil is placed in the depression of the shell and the top of the depression is covered with a cover plate.When used, the wire is connected to the coil. After the power is energized, gravity is generated on the plate, so as to realize the clamping of the thin plate between the pressure plate and the base. Because of the use of electromagnetic force clamping, the pressure plate can be made into a variety of artifacts' requirements. The artifacts with side wall can be processed, and the operation is very simple. CNC bending machine From now on, the development trend of CNC bending machine is mainly embodied in the th

How to improve efficiency by combining hydraulic bending machine and stamping die?

It's well-known that hydraulic press brake machine can only use bending mould for plate length bending processing, stamping die can only be used in  power press punching machine  as single mode, but if we can combine plate length bending and stamping die single molding effectively; For some products that are processed on line (such as profiles), it means that the production efficiency is several times higher. Substantial improvement in product quality; The sharp decrease in labor intensity. It has an inestimable effect on reducing the production cost. For the products of online processing, most of them are mainly punch holes. If we can make the bending machine similar to the punching machine, it will be better.  That is to make the press brake bending machine mold unloading workbench as workbench suitable for fixed stamping die, and as long as change the mould of the waste discharge to the back side (bottom row material for machine tool under the front board, is difficult.). The

Safety Operation Procedures for Three Roll Bending Machine

The upper roll of the rolling machine is in the central symmetrical position of the two lower roll. It acts vertically on the piston through the hydraulic oil in the hydraulic cylinder, and drives the two lower roll gears to move together and rotate through the last gear of the main reducer, so as to provide torque for the rolled sheet. The leveling plastic plate is made up of three roll bending machine, with the help of the upper roller's lower pressure and the rotation movement of the lower roll, so that the metal plate can be continuously bent through multiple passes. A permanent plastic deformation is produced to be rolled into the required cylinder, cone, or part of them. The drawback of the three roll bending machine is that the end of the plate must be prebent with the aid of other equipment. The rolling machine is suitable for large rolling plate machine with the thickness of 50 mm.  Safety operation procedures for  three roll bending machine cnc rolling machine by gl

How to choose a right shearing machine

Here is a brief introduction about how to choose the right shearing machine for your metal working, article from Ma'anshan Gilde CNC Machine Tool Co.,Ltd: 1. Shearing length*width*thickness If shearing width exceeds the back gauge's length, then the back gauge's length needs to be lengthened. If the sheet is thin, should add pneumatic rack. 2. Material of your sheet metal, shear's design is based on σb ≤ 450N/mm2 Different material,different requirements to the blades, also affect the shearing thickness. 3. User's requirement for straightness Guillotine shear is better than swing beam shear. 4. User requirements for parallelism Guillotine shear is better than swing beam shear. 5. User's requirements for speed Swing beam shear is faster than  guillotine shear . 6. User's requirements for distortion Guillotine's shearing angle is adjustable. It is advantageous to cut thin plate under the condition of reducing the shearing thickness. 7. User's customa

About Container and Transportation of GLDMA Machines

For a client buying sheet metal fabrication machinery, most worrying thing is how to guarantee the safe transportation and save the cost of it. Today let talk about this theme. Different with consumer goods, the machine has a large size and weight, like big size press brake and shearing machine, also with complex and precise structure. Suitable container and stable fixing is the key point. Widely used in machinery industry is 20' /40' GQ (general container), 40HQ (high container), 20' /40' OT(open top container). If the machine is much larger, flat rack container is the leading part. 20' GQ is a good choice for a small machine, like power press, ironworker and some duct forming machine. When the height is over 2100mm, need to level up to 40' HQ container. Some machine like pneumatic power press, as its height, need to be laid down in the container. But if the machine is too heavy and large, it's necessary to separate and use several containers. Such as
