The bending center specializes in solving complex sheet metal bending problems in metal forming. Its applications include steel cabinet enclosures (file cabinets, tool cabinets, exterior enclosures, electrical cabinets, communications cabinets, gas cabinets, water meter cabinets, etc.), kitchen appliances (refrigerators, air conditioners, stoves, etc.), furniture, ventilation, refrigeration, purification, door construction, decoration, elevators, and other related metal forming fields, suitable for bending a wide range of workpieces.The bending center achieves superior bend quality thanks to its angle correction database and servo motor technology.
The bending center can automatically create multiple bends for each side, including up/down bends, flat bends, and curved bends. Suction cup feeders and pressure arm feeders replace traditional bending center operating devices, expanding the range of products that can be bent.
The intelligent flexible bending center uses universal bending molds and realizes bending of various shapes through multi-axis concurrent linkage and full servo control. It can bend various complex shapes. It can bend right angles, non-right angles, arcs, up and down folds, and other complex shapes.
Traditional Production Model Faces Difficulties
Before partnering with the HOGI CNC bending center, the sheet metal shop had traditionally relied on manual bending to process workpieces. This traditional production model created numerous bottlenecks for the group. Because products were non-standard, each new workpiece required the creation of a new mold, along with mold changes and adjustments. This not only increased production costs but also significantly increased production preparation time. Furthermore, manual bending relies heavily on operator expertise. An unskilled operator could take two or even three times as long as a skilled worker to complete the same number of orders. Given the uncontrollable production schedule and the need to meet delivery deadlines, overtime was inevitable. Furthermore, due to the limitations of manual operation, product consistency within the same order was often difficult to achieve, undoubtedly posing a challenge to product quality.
HOGI CNC Bending Center Equipment Breaks Through Bottlenecks
The arrival of the HOGI CNC bending center is undoubtedly a booster for sheet metal processing plants to achieve cost control, increase efficiency, and ensure on-time delivery. The ABA automatic upper pressure adjustment mechanism on the multi-sided bending center acts as a universal bending die, enabling zero-second die changes for different workpieces, effectively reducing production time and lowering costs. Furthermore, the multi-sided bending center can be integrated with HOGI CNC bending center’s proprietary CNC software, allowing for one-click import of drawings and automatic generation of bending programs based on the workpiece contours. This streamlines programming, reduces production setup time, and significantly improves production efficiency. Regarding the increased production efficiency, a leader added, “In addition to significantly reducing equipment adjustment and die change time, the automation of the HOGI CNC bending center itself is a significant contributor to efficiency improvements. We’ve calculated that one HOGI CNC bending center is equivalent to eight conventional press brakes, yet requires only one-quarter the labor.” Thanks to the multiple advantages of the HOGI CNC bending center, short order delivery times are no longer a problem for Mianyang Jiancheng Group. In terms of product quality, the leader also said that the introduction of HOGI CNC bending center equipment has completely eliminated manual intervention in the bending process, replacing the previous production model that relied on the professionalism of operators to ensure product quality: “Now the products are completely bent automatically by the equipment, which is a guarantee for the consistency of product quality.” The source of this guarantee is the robot equipped with the HOGI CNC bending center’s multilateral bending center and the single-shot centering process – after the operator loads the material, the robot can automatically and quickly control all movements of the plate. Combined with the single-shot centering process that automatically positions the plate using a CNC positioning device, it can achieve one-time positioning to complete multilateral bending, control the error of plate shearing on the first bend, and effectively ensure the high quality of the product.
