Description

Efficient internal thread die matching method Technical Field The invention belongs to the field of die manufacturing and production management, and particularly relates to a high-efficiency internal thread die matching method. Background In the traditional internal thread die matching process, an operator usually needs to hold process cards, and goes to a die warehouse one by one to select and carry the dies, and the die matching process of each set of dies needs to consume about 15 minutes on average, so that the process is long in time consumption, and a plurality of potential hazards and efficiency problems exist. Because the specifications of the dies are similar and the information of the process card is abstract, operators are easy to misjudge when selecting the dies, so that the dies with wrong specifications are selected, the quality problem of products can be caused, excessive wear to production equipment can be caused due to mismatching of the dies, and even the production period is delayed. In addition, the traditional mode of matching has obvious defects in the aspects of information transmission and management, the information on the process card needs to be checked manually, and the real-time state of the die, such as whether the die is led up or not, whether maintenance is needed or not, is difficult to reflect in time, so that the risk of misoperation is further increased. Because of lack of digital management means, the storage, the acquisition and the return records of the die all depend on manual statistics, so that the efficiency is low, data distortion is easy to occur, and extra difficulties are brought to production planning and inventory management. Disclosure of Invention The invention aims to provide a high-efficiency internal thread die matching method, which aims to realize quick matching and accurate positioning of dies through an intelligent and digital management system. By constructing the mold database, the process database, the inventory database and the MES system, the invention not only can obviously shorten the mold selection time, but also can effectively reduce the manual misoperation and improve the production efficiency and the stability of the product quality.
