Talking About The Development Trend Of Rotary Bending Machine

Professional Pipe Bender

Today’s press brakes have developed rapidly in terms of system application and flexibility. Rotary bending machine plays a huge role in the forming and processing of modern sheet metal parts and has unlimited development prospects. Facing the new situation of the machine tool industry, we believe that the rotary bending machine will be better developed, bringing better production efficiency to product manufacturers and promoting the progress of the machine tool industry.

Bending machine tool is an essential configuration for industrial manufacturing, and it is also one of the necessary configurations. It has the characteristics of high precision, high speed, compounding, different compensation results, new control results, and automatic diagnosis. In the bending machine tool industry, informatization and networking are inevitable trends, and the basis of intelligence, each component of the result, is crucial to the quality and performance of the whole machine.Rotary bending machine

Bending machine market demand

  • Geographically, spin benders are popular in Canada and other North American regions. There are many torsion press brakes in Youngstown, Ohio, USA. CNC hydraulic press brakes are available in Asia in China, Japan, Korea and Singapore.
  • There are many torsion types of used hydraulic bending machines in India, the Philippines, and other countries. In Africa, such as South Africa, the torsion type of hydraulic bending machine is also mainly used. In Europe and Australia, CNC electro-hydraulic bending machines are used primarily.
  • From the point of view of cargo, if the hydraulic bending machine of higher tonnage exceeds 250 tons, the simple hydraulic type will not work well. The manufacturing cost of the 300-ton torsion axis CNC hydraulic bending machine is very high.
  • And close to the electro-hydraulic bending machine. Therefore, benders with more considerable tonnage are more suitable for designing CNC electro-hydraulic bending machines.
  • From an industry perspective, in some decoration industries, the accuracy of products is relatively high. But the torsion bending machine can’t satisfy it. So they prefer electro-hydraulic bending machines with high precision.
  • With industry competition and worker costs increasing, efficiency has become a more critical factor. Due to the fast speed of electro-hydraulic bending machines, many factories gradually began to use CNC electro-hydraulic bending machines.
  • However, many small companies intend to improve the precision of their products but do not have enough money to buy new electro-hydraulic bending machines. They will buy used numerical control electro-hydraulic bending machines.
  • Used prime line, Canada, and triumph CNC hydraulic bending machines are famous in many developing countries. Used hydraulic bending machines are ubiquitous in India, such as Ahmedabad, Kolkata, Delhi, Kerala. The global demand for bending machines is enormous, and the future development trend is also up-and-coming.

Reflect The Performance Development Trend Of Rotary Bending Machine

  • Multi-axis linkage processing, after the parts are clamped once on a CNC bending machine tool, automatic tool change, rotating spindle head, rotating worktable, etc., can complete multi-process and multi-surface composite processing, which not only has high finish but also dramatically improves efficiency.
  • Software and hardware are open, and users can develop CNC bending machine system software twice according to their needs. Manufacturers no longer limit the scope of use of users.
  • Flexible, the rotary bending machine system adopts a new generation of modular design, with broader functional coverage and more robust reliability, which can meet the needs of different users. The same group control system can automatically dynamically adjust the information flow according to other production processes and play the functions of the group control system.
  • Intelligence, the development trend of bending machines, is reflected in these places. In the technical field of bending machines, the research and application of real-time intelligent control are developing along the lines of adaptive management, fuzzy control, neural network control, expert control, learning control, feedforward control, etc. For example, programming expert system fault diagnosis expert system, when the system fails, diagnosis, maintenance, etc., are intelligent.

Care And Maintenance

  • Before performing maintenance or polishing of the rotary bending machine, the upper die should be aligned with the lower die and then put down and shut down until the work is completed. If you need to start the machine or other operation, select the mode manually and ensure safety. Its maintenance contents are as follows:
  • Hydraulic oil circuit
  • Weekly check the fuel tank oil level, such as hydraulic system maintenance should also be checked, the oil level should be below the oil window should be filled with hydraulic oil; the new machine should be changed after 2000 hours, after every 4000 to 6000 hours should be changed, each oil change, the tank should be cleaned; the system oil temperature should not exceed 70℃ if too high will lead to deterioration of oil quality and accessories damage.
  • Filter
  • Every time the oil is changed, the filter should be replaced or thoroughly cleaned, and the machine tool has related alarms or other filter abnormalities such as unclean oil quality, should be replaced; the air filter on the oil tank should be inspected and cleaned every three months, preferably once a year.
  • Hydraulic components
  • Clean hydraulic components (substrate, valve, motor, pump, tubing, etc.) every month to prevent dirt from entering the system, can not use cleaning agent; one month after the new machine, check the bending of each tubing for deformation, if abnormal should be replaced, after two months of use, all accessories should be fastened, shut down when doing this work, the system pressureless hydraulic bending machine includes bracket, workbench and clamping plate, Place the workbench On the frame, the worktable is composed of a base and a pressing plate, the floor is connected with the clamping plate through a hinge, and the base is composed of a seat shell, a coil and a cover plate.


  • The bending sequence of the rotary bending machine.
  • Short side and then long side: When all four sides are bent, fold the short side first and then fold the long side, which is conducive to the processing of the workpiece and the assembly of the bending mold.
  • Periphery and then middle: Under normal circumstances, it is generally bent from the periphery of the workpiece to the center of the workpiece.
  • Local and then whole: If some structures inside or outside the workpiece are different from other bends, it is generally necessary to bend these structures first and then fold other parts.
