Characteristics of bending machine press brake tools materials：

Bending machine press brake tools is an important tool for sheet metal forming and processing, the material needs to have high strength, high hardness, high wear resistance and other characteristics. Commonly used bending machine press brake tools materials are the following:

1. Hard and soft alloys: with high hardness and great strength, especially suitable for making punches and other small press brake tools.
2. High-speed steel: high hardness, low wear, high temperature resistance, good processing performance, suitable for the production of large press brake tools and press brake tools of complex shapes.
3. Alloy tool steel: good abrasion resistance, high strength, suitable for the production of high-volume press brake tools and high-demand press brake tools.

When choosing the material of the bending machine press brake tools, you need to determine the type of material according to the characteristics of the processed material and the requirements of the press brake tools parts.

Welding techniques for bending machine press brake tools：

Bending machine press brake tools because it needs to withstand greater force and pressure, so the press brake tools interface and cracks are more likely to crack or broken. In this regard, we can take the welding repair method. Welding methods are divided into manual welding, gas welding, arc welding, etc., different welding methods for different press brake tools materials and types. When welding bending machine press brake tools, you need to pay attention to the following skills:

1. Surface Cleaning: The surface of the press brake tools needs to be cleaned before welding to ensure the quality of welding.
2. Temperature control: When welding, care needs to be taken to control the temperature to avoid generating excessive heat leading to deformation or damage.
3. Selection of appropriate welding consumables: Select appropriate welding consumables and welding methods according to the specific conditions to ensure the welding effect.
4. Post-welding treatment: After completing the welding, the weld needs to be polished and adjusted to ensure a flat surface.

Maintenance of bending machine press brake tools：

1. Regular cleaning: bending machine press brake tools in the process of use, will accumulate metal shavings, oil and other substances, affecting the bending effect and processing quality. Regular cleaning of the press brake tools is particularly important. You can use wire brushes, solvents and other tools for cleaning to keep the press brake tools clean and smooth.
2. Regular lubrication: the bending machine press brake tools will produce heat due to friction during operation, in order to maintain the normal operation of the press brake tools and extend its service life, the press brake tools should be regularly refueled. The use of lubricating oil or grease for lubrication can reduce the friction loss of the press brake tools and reduce noise.
3. Avoid overuse: excessive use of the bending machine press brake tools will lead to its fatigue rupture and deformation, so in the production process should pay attention to controlling the number of times of use and bending angle, to avoid excessive pressure and damage to the press brake tools.
4. Attention to storage and maintenance: when the bending machine press brake tools are not in use for a while, they should be properly stored and well maintained to prevent rust and deformation. You can apply a layer of anti-rust oil and place it in a dry and ventilated place to avoid collision and damage with other items.

What are the types of bending machine press brake tools：

There are many kinds of bending machine press brake tools, generally there are right-angle bending with standard upper die, sharp knife upper die, flattening knife die, R-shaped knife die, avoidance of the upper die, 1V lower die, 2V lower die, 3U, 4V lower die, Urethane lower die, hard rubber lower die, lower die guide, lower die seat, section of the difference between the bending press brake tools, press brake tools bending press brake tools, combined bending press brake tools, no scar bending press brake tools, etc., and according to the situation, design a variety of non-standard press brake tools. We can also design all kinds of non-standard press brake tools according to different situations.

1. Ordinary standard upper and lower press brake tools: used for bending 90 ° -180 ° angle. Advantages: thick and thin plate universal, durable, and the most widely used.
2. Sharp Die: For bending 20°-180° angles. Advantages: can bend smaller angles and sizes, bending R curvature is smaller, beautiful, sharp edges.
3. Big Bend Die (gooseneck die): also called big bending knife, used for bending 30 ° -180 ° angle. Advantages: used for standard press brake tools and pointed die can not complete the “U” shaped products, applicable to a wide range.
4. Flattening die: used to shoot the dead edge, with the tip of the die with the application of the tip of the die to bend the work piece into an angle of less than 45 °, and then use the flattening die pressed into the dead edge, mainly used for the reinforcement of the frame.
5. Discrepancy die: (also known as “Z” die) is mainly used for one-time bending of small-size “Z” type work pieces, divided into fixed and adjustable two kinds.
6. Forming die: (including arc die, door frame one-time press brake tools die, U-word press brake tools , lamp post press brake tools, etc.) usually for the more complex products bending, including a variety of bending angles and styles, so as to design the one-time bending press brake tools  die, in order to improve the bending accuracy and efficiency.
7. The same core press brake tools: usually refers to the supporting CNC bending machine and the use of the lower die, composed of press brake tools bracket and segmented lower die, the same core refers to the use of any slot can only be changed to the specified slot, without the need to re-centering the upper and lower die position, the change of the press brake tools is very convenient, and high processing accuracy.

Summarize：

Selection of bending machine press brake tools material needs to be based on the work piece material, processing accuracy and processing conditions and other factors for comprehensive consideration in order to meet the processing requirements. Alloy die steel, ordinary die steel, carbide, stainless steel and other materials have their own characteristics, you can choose according to the actual situation. Finally, the key to choosing the material of the bending machine press brake tools is to choose a reliable quality and cost-effective material to achieve the best processing results and cost-effectiveness.
