A guide to choosing the right press bending tool for your needs

The importance of press bending tool

The importance of press bending tool in processing cannot be ignored. A press bending tool is a tool used to bend sheet metal into the desired shape. They can be used in various industries such as automobile manufacturing, appliance manufacturing, construction and aerospace, among others. Proper selection and use of bending dies is critical to product quality and production efficiency.

First of all, choosing the right bending die can ensure product quality. The design and manufacturing quality of the die directly affects the accuracy and quality of the metal sheet during the bending process. A precise die can ensure the accuracy of product bending angles, curves and dimensions. In contrast, choosing low-quality or unsuitable dies can lead to inaccurate bending, dimensional deviations, or even breakage of the product. Therefore, choosing a high-quality bending die is very important to ensure product quality.

Secondly, choosing the correct bending die can improve production efficiency. Proper dies can provide higher production speed and less human error. For example, a set of highly efficient automated bending dies can achieve fast and accurate continuous bending, thereby greatly improving production efficiency. In addition, the reliability and durability of the die will also affect the production efficiency. Using durable dies reduces the frequency of maintenance and replacement, saving time and money.

In short, choosing the correct bending die has an important impact on product quality and production efficiency. Appropriate dies can ensure the accuracy and quality of products, while increasing production speed and reducing human error. Therefore, it is very critical to choose high-quality and suitable bending dies during processing.

Types of bending machine tool

The bending machine die is an auxiliary tool for forming and processing sheets. It consists of a variety of parts, and different dies have different shapes and parts. The physical state of the material is changed by the pressure applied by the bending machine, and the shape of the material is changed to obtain the desired shape.

From a structural point of view, bending machine dies can be divided into two categories: upper dies and lower dies. In most cases, the upper die is the active die (moving die), and the lower die is the passive die (fixed die), but there are also some cases where the opposite is true. However, the overall form remains the same.

In terms of use, bending machine dies are generally divided into standard dies and special dies. The angle of the tool tip of the standard upper die is usually 30 degrees (the actual angle is 26-28 degrees), 60 degrees, 78 degrees to 88 degrees, etc., while the angle of the lower die groove is roughly 30 degrees, 45 degrees, 60 degrees, 80 degrees to 90 degrees, etc.

According to the shape of the upper die, the bending machine die can be divided into sharp knife die, arc die, curved knife die and forming die. The sharp knife die is usually 30 degrees and 60 degrees, and occasionally there are special angles such as 45 degrees and 55 degrees. The arc die is mainly designed according to the diameter and arc length of the arc, and there are many types. Scimitar dies are mainly used for avoidance in “U”-shaped workpieces or multi-bending.

The most complex is the forming die, which can be one-piece or combined. Generally speaking, the combined die is designed, manufactured and used together with the upper and lower dies. From the perspective of production cost, the manufacturing cost of the one-piece forming die is relatively high (especially for large-sized dies), and it is difficult to control the accuracy. The combination die has great advantages in large-size and complex-shaped dies.

According to the function, the bending machine die can be divided into a single die and a multi-functional die. A single die can only be used to process a single type of workpiece, while a multi-functional die can process different types of workpieces, and some can also be disassembled and assembled. We call them composite dies, such as segment differential dies and forming dies.

According to the number of grooves of the lower die, the bending machine die can be roughly divided into single V die, double V die and multi V die. There are only one or two grooves on the surface of single V die and double V die, which are common in CNC bending machines and have high precision because they have fixed references, also known as concentric dies, which can be exchanged arbitrarily. The multi-V lower die is usually a square die, and its four surfaces have several grooves of different sizes. The advantage is that the number of grooves is large, and it can adapt to bending of sheets of various thicknesses.

How to choose the press bending tool?

1. Understand the requirements of the machined parts: First, carefully read the engineering drawings or related specifications of the machined parts. Understand the size, shape, surface requirements and other related requirements of the machined parts.

2. Analyze the machining process: Understand the die types and functions required in the machining process. For example, dies may require processes such as stamping, injection dieing, casting, etc. Select the corresponding die type according to the requirements of the processing process.

3. Consider the material properties: Choose the appropriate die material according to the material properties of the processed parts. For example, for parts that need to withstand high temperatures, you can choose die materials with good heat resistance.

4. Consider the processing accuracy: Select the appropriate die according to the dimensional accuracy requirements of the processed parts. If the parts need to be processed with high precision, the manufacturing precision of the die also needs to be higher.

5. Consider the production batch and cycle: Select the appropriate die according to the production batch and cycle requirements of the processed parts. If you need to mass-produce parts, you can choose a die with good wear resistance to improve service life and production efficiency.

6. Consider economy: Consider the manufacturing cost, maintenance cost and service life of the die comprehensively, and choose economical and practical die specifications. Weigh the return on investment of the tooling against the projected service life of the machined part and market demand.

7. Learn from experience and professional advice: Discuss with die manufacturers, engineers or relevant experts based on your own experience and professional opinions, and obtain their suggestions and guidance.
