2D Frame Bending and Welding Machine: An Efficient and Precision Solution for Paper Towel Holder Production

In the paper towel holder production field, the 2D frame bending and welding machine, with its integrated "forming + welding" core advantage, has become a key piece of equipment for improving production efficiency and product consistency. Designed specifically for iron wire, it is compatible with round, flat, and square wires with diameters ranging from 2-6mm. It maintains a stable speed of 8-10 pieces/minute, meeting the batch processing needs of paper towel holder frames. While maintaining high precision and strong adaptability, it provides full-process automation support for metal product production.

I.  Power and Structure: Stable and Efficient Core Configuration
The equipment's power system is centered around a 5.8kW servo motor unit, meticulously configured to precisely meet the needs of each process: a 2.3kW wire feed servo ensures strong and stable wire transport, a 1.5kW bending servo drives four axes for complex bending, a 1kW cutter servo ensures clean and smooth cutting, and a 1.0kW lift servo provides flexible adjustment of processing height. These multiple motors work together to seamlessly integrate wire feeding, bending, cutting, and welding.

The equipment's structural design combines a high-strength chassis with precision components. The 28 straightening wheels are made of high-quality 45# steel, using multi-stage straightening to eliminate wire stress and prevent distortion of the paper towel holder frame. The three sets of wire feed rollers are made of national standard Cr12 material. After fine polishing and heat treatment, they achieve a hardness of 58°, offering excellent wear resistance and ensuring stability during long-term high-speed wire feeding (up to 90m/min). The bending molds are precision-machined from SKD11/51 material, achieving a hardness of 62° and enduring high-frequency bending impacts, ensuring long-term stable bending angle accuracy.

II. Processing Precision and Adaptability: Meeting Diverse Production Needs
As a key piece of equipment in paper towel holder production, its precision control addresses industry pain points: bending accuracy of ±0.5mm and wire feeding accuracy of ±0.5mm ensure minimal dimensional variation within the same batch of paper towel holder frames, significantly reducing subsequent assembly challenges. The bending motion supports 150 external rotations per minute within a ±180° angular range. The inner and outer molds can achieve 360° clockwise and counterclockwise rotation, as well as vertical and horizontal movement. Combined with four-axis linkage, it easily produces complex shapes, including right angles and circular arcs, for paper towel holders.

The machine's compatibility extends beyond single-size specifications: it covers wire diameters from 2-6mm and is compatible with a variety of materials, including iron wire, stainless steel, and carbon steel. Whether it's the main frame or detailed connectors, the machine can be formed using 300 action settings. With an unlimited circumference range, it can process compact frames for small desktop paper towel holders or long structures for large public facilities, meeting diverse product design requirements.

III. Intelligent Operation and Storage: Efficient and Convenient Production Management
The machine features a dual-system "keyboard + touchscreen PLC" system, a high-performance 32-bit processor, an interface that supports switching between Chinese and English, and built-in data upload and download functions for convenient parameter synchronization across multiple devices. With a storage capacity of 4,000 sets of data (each containing 300 actions), the machine can quickly access processing programs for different paper towel holder sizes, significantly reducing changeover time.

The core of its efficiency lies in its automated process: from automatic feeding, straightening and cutting, to bending, forming, and automatic material removal, the entire process requires no human intervention. Two sets of robotic grippers, coupled with precise motion control, can achieve complex bending angles. The welding module, equipped with a 40kW welding transformer, ensures secure and smooth joints, preventing problems such as cold solder joints and desoldering on the paper towel holder frame, while maintaining a balanced structural strength and aesthetic appearance.

IV. Mechanical Performance and Practical Value: Boosting Production Speed and Efficiency
Weighing 1,100 kg, the machine boasts a compact yet stable structure, making it suitable for any workshop layout. In actual production, taking a 200*200mm square frame as an example, the efficiency can reach 15-20 pieces/minute, far exceeding traditional manual processing. The pneumatic system is equipped with 9 cylinders and 5 solenoid valves, providing stable power to components such as the clamp and mold, ensuring rapid response.

For paper towel holder manufacturers, the value of the 2D frame bending and welding machine lies not only in its efficient output of 8-10 pieces/minute, but also in the "standardized production" achieved through microcomputer program control. From wire to finished frame, parameters are fully controllable and errors are extremely small. This not only reduces labor costs but also improves product qualification rates, making it an ideal choice for intelligent upgrades in metal product processing.
