Nowadays, the competition among manufacturing industries is becoming more and more fierce. It is necessary for enterprises to produce high quality products in a short period of time. Improving the quality of die is the key to the leap of manufacturing industry. Under the condition of high precision, low cost and high efficiency, the mould can produce more qualified parts and die materials for a longer time and more times, which not only meets the customer's requirements for product quality, but also takes into account the cost of materials and the strength in the set period, and of course, according to the type of mould and the selection of die materials. Material selection is based on working mode, processing speed and main failure modes.
It is necessary to reduce the scope of disassembly and assembly when repairing a part in the design, especially when replacing vulnerable parts, so as to reduce the scope of disassembly and assembly as much as possible. The manufacturing process of the die is also an important part of ensuring the quality of the die. The processing method and precision in the process of the die manufacturing will also affect the service life of the die. The accuracy of each part directly affects the overall assembly of the die. In addition to the influence of the accuracy of the equipment itself, it is necessary to improve the processing methods of the parts and the technical level of the fitters in the process of grinding the die to improve the processing accuracy of the die parts. If the overall assembly effect of the die fails to meet the requirements, the die will be tested. It will have a great influence on the overall quality of the die if the probability of the die moving under abnormal conditions is increased.
Surface strengthening of the main forming parts of the die is carried out to improve the surface wear resistance of the die parts, so as to better improve the quality of the die. For surface strengthening, different strengthening methods should be selected according to the different use of the die. Correct use and maintenance of the die is also a major factor to improve the quality of the die. Quality is the life of the brand. The quality of the mould will directly affect the quality, output, cost of the product, the cycle of new product production and old product renewal, the speed of product structure adjustment and market competitiveness. Therefore, the economic situation has put forward higher and higher requirements for the quality of the mould. Whether it is the designer and manufacturer of the die, the designer of the parts, or the user of the die, they should be actively concerned about the problem.
