2D Frame Bending and Welding Integrated Machine: A New Benchmark for Efficiency in Kitchen Knife Rack Production

In the field of kitchen knife rack production, the forming precision and production efficiency of iron frames directly determine product quality and market competitiveness. The 2D frame bending and welding integrated machine, with its precise processing performance and high production capacity, has become the core equipment for large-scale production of kitchen knife racks, bringing unprecedented technological innovation to the industry.

This equipment is specially built for iron kitchen knife racks, adapting to iron wires with a diameter of 3-8mm. It can perfectly process round wires, flat wires, and square wires. Its production speed is stable at 10-15 pieces per minute, and when taking a 200*200 square frame as a sample, the efficiency also maintains this level, which is nearly 3 times higher than that of traditional equipment, easily meeting the delivery requirements of bulk orders. For kitchen knife racks that focus on structural stability, the equipment's bending accuracy and wire feeding accuracy of ±0.5mm ensure that every frame connection is precise, avoiding the problem of unstable tool placement caused by dimensional deviations.

The performance advantages of the equipment come from precise parameter configuration and high-quality core components. The power system adopts Inovance servo motors with a total power of about 7.8kw, among which 4.0kw is responsible for wire feeding, 1.8kw drives bending, 1.0kw controls cutting, and 1.0kw drives servo lifting. All modules operate in coordination to achieve high-speed production. The maximum wire feeding speed reaches 25m/min, combined with 3 sets of wire feeding wheels made of national standard Cr12 (with a hardness of 58° after precision polishing and heat treatment), which significantly improves wear resistance while ensuring wire feeding accuracy and prolongs the service life of the equipment. The 28 forming molds are precision-machined with national standard Cr12 and high-quality materials SKD11/51, with a hardness of 62°, which is sufficient to meet the high-strength processing requirements of 3-8mm iron wires.

In terms of processing capacity, the equipment shows strong adaptability. The maximum bending speed is about 100 rpm, and the bending angle can reach 180°. The inner mold and outer mold can move down, move up, and rotate 360° clockwise and counterclockwise. Combined with a pneumatic system composed of 9 cylinders and 5 solenoid valves (with a maximum bending force of about 125 Nm), it can easily complete the complex multi-directional bending forming of kitchen knife racks. The cutting force of the cutter motor for 88 iron wires, paired with a 63KW welding transformer, ensures that the iron wires are cut smoothly and welded firmly, making the knife rack frame both beautiful and load-bearing.

The intelligent control system is the core competitiveness of the equipment. Equipped with a 32-bit high-performance PLC processor, it adopts a dual-system operation of control panel buttons and touch screen, supports Chinese-English switching, and has data upload and download functions, facilitating collaborative production of multiple devices and parameter sharing. The equipment can store 4000 sets of data, with each set containing 300 actions. Various types and specifications of kitchen knife rack products can be produced through different combinations of actions. The mechanical actions are precisely controlled by microcomputer programs, realizing an integrated process of automatic feeding, returning, straightening, cutting, and bending forming. Combined with 2 sets of mechanical grippers, it greatly reduces manual intervention, lowers labor costs, and avoids human operation errors.

The equipment also performs excellently in practicality and safety. With a weight of 1100KG, it is suitable for the layout needs of most production workshops. The power supply design of three-phase 380V + grounding wire and the stable performance of the Yaqi servo system ensure the long-term safe operation of the equipment. For kitchen knife rack manufacturers, this 2D frame bending and welding integrated machine is not only a tool to improve efficiency but also a solid backing for quality control. From precise forming to firm welding, from multi-specification adaptation to intelligent operation, it comprehensively helps enterprises gain advantages in the fierce market competition.
