1. Bending dies are manufactured from high-quality steel through special heat treatment, possessing characteristics such as high hardness, resistance to wear, and ability to withstand high pressure. However, each set of dies has a limit pressure it can withstand: tons per meter. Therefore, when using the dies, it is important to correctly select the length of the dies, including how much pressure is added per meter, without exceeding the pressure indicated for the dies.
2. To prevent damage to the dies, it is a rule that when setting the origin point, both the upper and lower dies with a length of over 300mm must be used. Only after setting the origin point correctly can the upper and lower dies of the same height be used. It is strictly prohibited to use segmented smaller dies for setting the origin point, and the origin point must be set according to the standard pressure within the press brake machine.
3. Due to the varying heights of different dies, when selecting dies on a machine, only dies of the same height should be used, and dies of different heights should not be mixed.
4. When bending products with high hardness or very thick materials, it is not allowed to use dies to bend steel bars or other cylindrical products.
5. When bending sharp angles or hemming corners, a 30-degree upper die should be used, first bending the sharp angle and then hemming the edge. When bending R angles, R-type upper and lower dies should be used.
6. When bending longer workpieces, it is best not to use segmented dies to reduce the marks from blade joints. It is preferable to use a single groove die because the outer corner R of the V-groove in a single groove die is larger, reducing the likelihood of bending marks.
7. When using dies, suitable upper and lower dies should be selected based on the material hardness, thickness, and length of the metal sheet. Generally, lower dies are used following a standard of 5-6T, with a length slightly longer than the material. For harder materials with greater thickness, a wider slot lower die should be used.
8. When selecting upper dies, it is important to understand the parameters of all dies and then decide which upper die to use based on the desired shape of the product being formed.
9. When using dies, clear thinking is essential. After setting the origin point on the machine, lock the upper and lower dies to prevent them from falling and causing injury or damage to the dies. During operation, pay attention to applying pressure gradually and avoid applying excessive force at once. Monitor changes in displayed data on the screen.
10. After using the dies, they should be promptly returned to the die rack and stored according to the markings. Regularly clean dust off the dies and apply rust prevention oil to prevent rusting and maintain die accuracy.
