How To Use The Double-Machine Press Brake In The Lamp Pole Industry

Street light pole production process

The production of street light poles generally includes processes such as opening, shearing, forming, welding, straightening, grinding, bending and spraying.
First, the steel coil is unfolded, twisted and cut into the required size through a simple coiling and opening production line; then the plate is beveled according to the size using a steel plate bevel shearing production line to meet the taper requirements. The core equipment is a lamp pole forming and press brake, which consists of two press brakes linked together and is equipped with a variety of lamp pole molds, suitable for bending and forming different types of lamp poles such as conical and polygonal. When producing conical lamp poles, they are bent in sequence through multiple knives, and finally the middle knife is used to complete the closure, and then the rounding machine is used to pull out the forming; polygonal lamp poles replace the corresponding molds, the process is similar, the operation is efficient and flexible, and it is the key link in the forming of lamp poles. Subsequently, an automatic seam welding production line is used for efficient welding, the weld is beautiful and firm, and the speed can reach 23 meters/minute. After welding, it is manually visually corrected by a straightening machine, and then automatically polished by a grinder to ensure that the pole body is clean and bright. If the design requires a curved arm, it can also be cold-bent by a pipe press brake, which is easy to operate. Finally, the surface is treated by an electrostatic spraying line to ensure uniform coating and strong adhesion, achieving aesthetic and anti-corrosion effects.

Synchronous double-link press brake

The synchronous double-machine linkage press brake achieves precise bending of product length and angle through the collaborative work of two press brakes. It has a self-processed rigid frame, which is stable, efficient and high-precision. The advanced control system ensures the synchronization of the movements of the two press brakes, thereby ensuring the consistency and accuracy of the bending angle. The synchronous double-machine linkage press brake is widely used in automobile manufacturing, aerospace, electrical manufacturing, metal processing and other industries. In these industries, the bending accuracy and production efficiency of metal sheets are required to be high, and the synchronous double-machine linkage press brake can meet these needs.

Why choose a double linkage press brake?

1.Reliability

The technical maturity of dual-machine linkage is better than that of large-tonnage and large-size press brakes. While achieving the same production capacity, it can effectively reduce the probability of failure, thereby ensuring smooth production of the enterprise.

2. Flexibility

When the workpieces produced by customer companies change and small parts need to be processed, the large-size press brake will cause the dilemma of "killing a chicken with a sledgehammer" due to its high energy consumption, and the production cost per unit workpiece will also increase accordingly, which is not conducive to the overall profit of the company. The dual-machine linkage effectively avoids such situations. In order to make the output of standard production line components meet the standards required by customers, we can use these two devices as separate press brakes: when we need to bend longer parts for special production lines, we also have a way to achieve this goal.

3. Value preservation

Equipment is not only a production tool for customer companies, but also a major asset. When the production and operation model of an enterprise changes, large-size equipment must be transferred to manufacturers with the same production model, and the circulation rate is relatively low. However, dual-machine linkage equipment not only maintains its value due to its regular size, but can also be split and sold.

Application of large bending machines in the light pole industry

The length of the workpiece has prompted the lamp pole industry to generally use two press brakes of the same tonnage, which are linked to achieve synchronous work. When producing conical lamp poles, a conical mold is installed, and multiple knives are bent. The last knife is bent in the middle, and a conical lamp pole is formed. Then the lamp pole is pulled out with a lamp pole rolling machine; when it is necessary to produce polygonal lamp poles, sign poles and high pole lamps, a polygonal special mold is installed, and multiple knives are bent. Finally, a knife is bent in the middle, and a multi-deformed lamp pole is formed, and then the lamp pole is pulled out with a rod rolling machine.

1. Dual-machine linkage, flexible and efficient

The double-machine linkage press brake uses two press brakes of the same specification, equipped with a double-machine linkage synchronization device to complete the linkage, synchronization, bending and other actions of the whole machine. The two devices work synchronously to meet the processing needs of ultra-long plates. Different upper and lower dies can be used to complete multiple bending of steel to form round tubes and polygonal tubes, and then the production of lamp poles can be completed through seam welding, etc. Even the processing of long lamp poles can be solved.

When customers need to process small parts, they can also run independently to achieve batch production. With a large opening and long stroke, the processing range of the equipment is expanded to meet the needs of different working conditions. Especially for the processing households that undertake external orders, it has greater flexibility and is a long plate processing tool for heavy industries such as ships, construction, machinery, street light poles, and power poles.

2. Rock solid, stable and reliable

Long plate workpieces are long and heavy. The frame and slide of DURMAPRESS press brake are made of imported large CNC floor boring and milling machines. They are clamped and processed in one time to ensure the parallelism and verticality of the machine. The machine body is combined with finite element analysis, annealing and vibration aging treatment to eliminate the deformation caused by welding and processing stress, ensuring the stability and reliability of the machine tool under long-term high load and high speed operation. It also adopts advanced integrated hydraulic system with stable and reliable performance.

3. Multiple tools to ensure accuracy

The oil cylinder is synchronously controlled by an electro-hydraulic servo system. The mechanical deflection compensation workbench not only meets the load-bearing requirements of long plates, but also compensates for deflection deformation, reduces the deviation of the bending angles at both ends and in the middle when bending long plates, and ensures the straightness and bending angle of the workpiece. The rear stop beam adopts a double-rail structure to effectively reduce the shaking of the stopper finger. Multiple tools ensure the accuracy, consistency and stability of long-size plate processing. The standard movable front support rack can move the support rack along the linear guide rail according to the length of the workpiece, and can be docked at any position, making the auxiliary bending more labor-saving and efficient. A variety of auxiliary devices such as laser protection and follow-up support vehicles are available for users to choose from, which can easily cope with large-scale workpiece processing, reduce labor intensity, and achieve safe and efficient production. In the future, DURMAPRESS will continue to focus on polishing products, improving services, and deepening the market, providing high-quality and reliable sheet metal forming equipment and system solutions to help industrial users upgrade their smart manufacturing and improve both quality and efficiency!
