What are bending machines used for?

As the core equipment in the field of metal processing, bending machine plays an indispensable role in the modern industrial system. Whether in automobile manufacturing, aerospace, or in construction engineering, home appliance production and other industries, the bending machine has become an important tool to promote the transformation and upgrading of the manufacturing industry with its high efficiency, precision and flexibility.

1.The main purpose of the bending machine

The core function of the bending machine is to bend and form the metal sheet, through the mold with the mold, can achieve a variety of angles, a variety of shapes of processing.

(1) Industrial production

In the automotive industry, bending machines are used to manufacture body sheet metal parts, such as door panels, hoods and roof parts. In the aerospace industry, bending machines are capable of processing machine jibs and structural support parts with high precision. In the home appliance industry, the molding of metal parts such as refrigerators, washing machines and air conditioning housings also rely on the precision of the bending machine.

(2) Construction Industry

Bending machines are widely used in the manufacture of steel structure supports, ventilation ducts and curtain wall skeletons. According to the Metal Forming Process Handbook (2023 Edition), the bending accuracy of modern bending machines can reach ± 0.1 mm, which is sufficient to meet the construction industry's stringent requirements for high precision.

(3) Customized Processing

As the market demand for personalized and small orders increases, the bending machine can realize complex processes such as U-shaped, V-shaped and multi-angle bending by replacing different molds, providing flexible customized solutions for enterprises.

2. Functional features and technical advantages of the bending machine

(1) High-precision control

- Adopting CNC system (such as E21, Delem and other brand solutions), the repetitive positioning accuracy is ≤ 0.01 mm, to ensure the consistency of mass production.

- Equipped with hydraulic or electric servo drive, the pressure adjustment range is wide (usually 10-2000 tons), adapting to the processing of different thickness of plates.

(2) Automation and Intelligent

- It supports automatic feeding, angle compensation and real-time monitoring functions to reduce manual intervention. For example, some models are equipped with AI algorithm, which can predict the rebound of the plate and automatically correct the parameters.

- Multi-axis linkage (e.g., Y1/Y2/X-axis synchronization) realizes complex curve bending and improves efficiency by more than 30% (Source: ICMA 2022 report).

(3) Safety and energy-saving design

- Equipped with grating protection and emergency braking device, complying with ISO 12100 safety standards.

- Energy consumption of servo motor models is 40%-60% lower than traditional hydraulic presses, and it automatically enters into dormant mode when no load.

3. Comparison of key parameters of different types of bending machines

As can be seen from the table, the hydraulic bending machine is suitable for large tonnage, large workpiece processing; servo bending machine emphasizes energy saving and precision processing of small and medium batches; CNC bending machine in terms of precision and intelligence has obvious advantages.

4. Application areas of bending machine

(1) metal processing

bending machine in the field of metal processing is widely used, can be bending sheet metal into the required various shapes, such as bending into a thin sine, V-shaped, U-shaped and so on. These shapes of parts or components are widely used in home appliances, communications, aviation, rail transportation and other fields.

(2) Construction

In housing construction, bending machines are used to process building materials, such as bending pipes, door frames, window frames, stair handrails and so on. The fast processing and high efficiency of bending machines accelerate the progress of building construction.

(3) Machinery Manufacturing

In the field of machinery manufacturing, bending machines are used to manufacture a variety of mechanical parts, such as gears, bearings, racks and so on. They are widely used in automobile manufacturing, aerospace, machinery manufacturing and other fields.

(4) Automobile Manufacturing

Bending machines also play an important role in automobile manufacturing. Doors, roofs, hoods, body parts, etc. of automobiles need to be processed by bending machines.

(5) Other fields

In addition to the above fields, the bending machine can also be applied to other fields, such as electronics, plastic products, medical equipment and so on. In the manufacturing industry, the bending machine is widely used.

Bending machine is not only the key equipment for metal forming, but also an important force to promote the intelligent and green development of manufacturing industry. With the continuous upgrading of technology, the bending machine will play a greater value in more industries, helping enterprises to improve production efficiency and market competitiveness. It can be predicted that in the future industrial manufacturing map, bending machine will continue to maintain its irreplaceable position.
