The process of the bending machine mold is generally forging --- tempering --- rough milling --- rough planing --- heat treatment --- rough grinding --- fine grinding --- demagnetization --- test die --- Inspection --- Packaging and storage.
The material of the bending machine mold is generally T8 or T10, and better 42CrMo, Cr12mov materials, etc., it mainly requires high strength, high toughness and good wear resistance, choose cold work die steel. 42CrMo is mainly used for CNC bending machine molds. The practical performance can be satisfied, and the process performance is also good. The precision of the bending machine we made is: the parallelism of the upper die is 0.02mm, the center tolerance is within 10 seconds; the parallelism of the lower die is 0.03mm, and the slot tolerance is within 10 seconds.
The other is the mold design.
1. In order to select the proper bending machine mold for the bending machine equipment, we must first have a global grasp of the type of bending machine. The specific needs to understand are the brand, size and even the actual tonnage of the bending machine. After you are familiar with these factors, you can use these materials as factual basis when choosing the mold.
2. If you encounter a bending machine with a brand that is too vague to be visible due to its long service life, it is recommended to send the sample of the bending machine mold to the manufacturer as much as possible to customize.
3. If the use of a combination of bending machine molds is involved in production, the degree of matching between the upper and lower molds is usually higher. If the matching is not in place, the results produced by the bending process of the workpiece may not meet the production quality specifications and requirements. In addition, the special-shaped mold is our main target. If you need to make a mold, you can design the mold according to the product!
