What are the effects of bending mold quality?

Under the pressure of the bending machine, the blank is made into a tool with a specific shape and size. What are the effects of bending the quality of the mold?

First, the design of the workpiece should be reasonable, and the best structural scheme should be selected as much as possible. The designer of the workpiece should consider that the technical requirements of the workpiece and its structure must conform to the craftability and feasibility of the mold manufacturing.

2. The design of the mold is the most important step to improve the quality of the mold. Many factors need to be considered, including the selection of the mold material, the usability and safety of the mold structure, the machinability of the mold parts and the convenience of mold maintenance. These should be considered as thoughtfully as possible at the beginning of the design. In the design, it is necessary to reduce the range of disassembly and assembly when repairing a certain component, especially when the consumable parts are replaced, and the disassembly and assembly range is minimized.

The manufacturing process of the three-fold bending mold is also an important part of ensuring the quality of the mold. The processing method and processing precision in the mold manufacturing process also affect the service life of the mold. The accuracy of each component directly affects the overall assembly of the mold. In addition to the influence of the accuracy of the equipment itself, it is necessary to improve the machining accuracy of the mold parts by improving the machining method of the parts and improving the technical level of the fitter in the mold grinding process. If the overall assembly effect of the mold does not meet the requirements, the probability of the mold being operated in an abnormal state will be increased in the trial mold, which will have a great influence on the overall quality of the mold.

4. Surface strengthening of the main molded parts of the mold to improve the surface wear resistance of the mold parts, thereby better improving the quality of the mold. For surface strengthening, different strengthening methods should be used according to the molds for different purposes. For example, the punching die can be made by electric spark strengthening, hard alloy surfacing, etc., in order to improve the wear resistance and compressive strength of the surface of the mold parts; the hot-working die steel parts such as die-casting molds and plastic molds can be nitrided (hard nitrogen). Treatment) to improve the wear resistance, thermal fatigue resistance and abrasion resistance of the parts; the drawing die and bending die can be treated by sulfurizing to reduce the friction coefficient and improve the wear resistance of the material; carbonitriding (Soft nitriding) can be applied to the surface strengthening treatment of various types of molds. In addition, a kind of FCVA vacuum-plated diamond film technology developed in recent years can form a protective film which is extremely firm and smooth and evenly compacted on the surface of the part. This technology is especially suitable for mold surface protection. Processing is also a significant method to improve the quality of the mold. Of course, if the part is a trial product or the production batch is quite small, it is not necessary to perform surface strengthening treatment of the mold part.

5. The correct use and maintenance of the mold is also a major factor in improving the quality of the mold. For example, the installation and debugging mode of the mold should be appropriate. In the case of hot runners, the power supply wiring should be correct, and the cooling water circuit should meet the design requirements. The parameters of the injection molding machine, die casting machine and press in the production of the mold should be consistent with the design requirements. and many more. When the mold is used correctly, the mold needs to be regularly maintained. The guide post, guide sleeve and other parts with relative movement of the mold should be filled with lubricating oil. For each of the forging mold, plastic mold and die-casting mold, A lubricant or mold release agent should be applied to the surface of the molded part before molding. Planned protective maintenance of the mold and data processing during the maintenance process can prevent mold problems in production and improve maintenance efficiency.
