How sheet metal machining reduces the bender setup time
- 2020-10-28 11:13:43 -

In recent years, sheet metal processing plants are better at complex bending machine preparation technicians are becoming more and more tight, the factory mostly depends on the operator to complete the preparation and operation of the bend machine. The sheet metal processing industry has made a number of technological advances in machine tools and molds, and today machine tools can be punched, cut and bent with more speed and precision than expected.

CNC bending machine

Standard operating procedures are performed to ensure consistency and reduce multiple setup parts and the resulting material waste. These SOPs not only help to minimize machining preparation time, but also improve the consistency of bend sequence operations and reduce part deviations caused by individual operators.

A list of preparations

For recurring machining tasks, one of the means available to the bender operator is to use a "preparation list". The preparation documentation documents the molds used for each use and tips on specific machining tasks, which should be used each time the processing task re-emerges.


The factory should consider using some snapshots to record mold positioning and dedicated stops. These photos can also be used as a reference for future applications.

Loading on

Another important means is that the loader mold must be loaded when the machine is fully open, providing the operator with a more accessible workspace and a safer working environment.

Professional tools

The plant should also consider the use of appropriate procedures and tool systems, such as top and bottoming units, to enable workers to complete regular processing tasks more quickly and efficiently.

Accessibility features

Many step molding mold systems include punch seats, button-operated safety clips, fast-changing 2V die molds and electric pressing mechanisms, so the operator can change molds very quickly alone. These systems also help operators perform tasks more independently and efficiently without compromising safety.

Segment the mold

Make finely ground segmented mold components according to the bend length required, without having to take the time to cut the mold to a certain length. Fine-grinding molds also reduce or omitt gasket adjustment needs. Segmented molds are lightweight and well handled, thus reducing physical exertion and fatigue and the possibility of accidents. In order to extend the service life, the fine grinding mold is also hardened and surface-reinforced.

Mold identification

Almost all of the molds now have information about laser etching, making it easy for workers to quickly identify, plan and reorder the molds. This information generally includes category numbers, tip angles, radius, V-shaped grooves, lengths, and rated tonnages.

Mold storage

Saving molds in cabinet groups provides the dual benefits of increased safety and improved material/tool management, utilizing an orderly storage system without having to look through tool racks for a custom-length mold. In addition, orderly storage allows managers to monitor mold status more vigilantly, ensuring high-quality inventory, identifying mold wear and damage in a timely manner, and determining how and when molds are replaced.

Use machine tool machining characteristics

The new bender offers advanced functionality and many features that help workers run the machine more efficiently, and operators who master the new machine control features can take advantage of these features to improve efficiency.

Work piece mold specification memory

Most of the new CNC benders have one thing in common: the ability to store work part specifications and all relevant processing information, such as mold model, position and bend order. Moreover, the CNC feature enables operators to store and access the tool library, making it easy to manage tool inventory.

Material thickness detection

When using finely ground molds, the bender detects changes in material thickness and performs real-time bend calculations, reducing the number of parts with too large or insufficient bend angles.

3-D graphical display and bend simulation

As the work piece bends and forms, these functions display the part bending process on the controller screen to avoid material scrapping due to incorrect part molding.

Offline programming

Offline programming of the bender saves preparation time because workers do not have to prepare parts machining procedures, which can be prepared by technicians and passed down to the bender.

Universal mold height

Universal mold height mold series, you can use the "plug and play" function to simplify complex grading mold adjustment. The general mold height mold was developed successfully with the appearance of CNC vertical moving rear stop material. In order to accurately utilize the principle of "universal mold height", vertical CNC control is necessary because the universal mold height is achieved by maintaining the same height (from the lower die base) at the bottom of the die opening. When the die opening is large, the total height of the die must be increased accordingly. This is why universal mold height molds no longer need to use special pads or special gaskets to drive the mold to close synchronously.

Small and complex parts often require offset bending, 90-degree bending, and leveling, and preparation typically requires multiple machine tools or equipment. A graded or universal mold height mold enables this operation to be done by a bender in the case of one loading. With the universal mold height mold, the operator can install 30-degree mold, partial head mold, flat mold and goose-neck mold on the same mold base and complete the entire processing of the parts.

Make the most of bending technology: Metal processing plants with benders are currently facing complex problems, and high raw material costs make every blank a good product. A sheet metal processing plant that reacts quickly and is willing to change the operation of bend molding sections to meet current needs reduces preparation time, resulting in greater production capacity and reduced scrap rates. Better use of storage and inventory systems, integrated use of machine tool functionality and full exploration of human resources, is an effective way to help bend molding workshop to improve efficiency and productivity.
