Abstract
Description
Technical Field
[0001] This invention belongs to the field of mold manufacturing and production management, and in particular relates to an efficient method for matching internal thread molds. Background Technology
[0002] In the traditional process of matching internal thread molds, operators typically need to carry process cards and go to the mold warehouse one by one to select and transport the molds. The matching process for each set of molds takes an average of about 15 minutes. This process is not only time-consuming but also has many potential hidden dangers and efficiency problems. Because the molds are similar in size and the information on the process cards is relatively abstract, operators are very prone to misjudging when selecting molds, resulting in the selection of molds of the wrong specifications. This can not only cause product quality problems but also cause excessive wear and tear on production equipment due to mold mismatch, and even delay the production cycle.
[0003] Furthermore, traditional mold allocation methods have significant shortcomings in information transmission and management. The information on the process cards needs to be manually verified, making it difficult to reflect the real-time status of the molds, such as whether they have been used or require maintenance. This further increases the risk of operational errors. Due to the lack of digital management tools, the storage, use, and return records of molds all rely on manual statistics, which is not only inefficient but also prone to data distortion, bringing additional difficulties to production planning and inventory management. Summary of the Invention
[0004] The purpose of this invention is to provide an efficient method for matching internal thread dies, aiming to achieve rapid matching and precise positioning of dies through an intelligent and digital management system. By constructing a die database, process database, inventory database, and MES system, this invention can not only significantly shorten die selection time but also effectively reduce human error and improve production efficiency and product quality stability.
[0005] To achieve the above objectives, the present invention provides a method for efficient internal thread mold fitting, comprising the following steps: For tooling and dies used in the production of internal thread products, establish a database containing the geometric dimensions of the dies; Based on the manufacturing process of internal thread products, construct a database of dimensional parameters for corresponding mold combinations; For each type of internal thread product specification, establish a database containing product specification parameters, technical requirement tolerance ranges, and technical requirement numbers; Establish an inventory database for all tooling and dies used to produce internal thread products, including the storage location and quantity of the dies. By linking and integrating the above databases, a MES system program for quick matching of internal thread molds is formed. When producing specific internal thread products, input the corresponding product technical requirement number, and the system will retrieve and match the corresponding tooling mold and storage location number. Select and requisition tooling molds based on the storage location number provided by the system, and double-verify the mold and product specifications after selection.
[0006] Preferably, the tooling molds include reducing molds, threaded mandrels, sliding mandrels, mandrels, spinning rings, steel balls, pre-diameter molds, and sizing molds. The basic specifications and application conditions of each tooling mold are recorded in the corresponding mold geometry parameter database.
[0007] Preferably, the mold geometry parameter database is equipped with a dynamic maintenance mechanism, allowing mold managers to update information on new mold specifications in a timely manner.
[0008] Preferably, the mold combination size parameter database accurately matches each product specification with its corresponding tooling mold combination, so that only the product specification needs to be entered to obtain the size parameters of the entire mold.
[0009] Preferably, the product specification database assigns a unique number to each product specification to facilitate rapid identification and traceability during the production process.
[0010] Preferably, the inventory database reflects the storage location and inventory quantity of molds in real time, supporting mold allocation and replenishment decisions.
[0011] Preferably, the MES system for matching internal thread molds integrates the mold combination database, product specification database, and inventory database to achieve efficient data linkage and intelligent analysis.
[0012] Preferably, after the system retrieves and matches the required tooling mold, it further displays the mold's storage location number so that the operator can quickly locate and retrieve it.
[0013] Preferably, the dual verification mechanism includes verification of the matching of product specifications, technical requirement numbers, and molds used, to ensure that the molds are highly matched with the production tasks.
[0014] Preferably, the database can be updated by a designated person to adapt to new product specifications, process changes, or adjustments to customer requirements.
[0015] In summary, the present invention has the following beneficial technical effects: The digital management system eliminates the inefficiencies of information ambiguity and manual searching inherent in traditional mold matching, significantly improving the accuracy and efficiency of mold finding and shortening matching time. The dynamic maintenance mechanism records changes in molds and processes in real time, quickly adapting to new specifications and requirements, making the production process more flexible. The quick-match algorithm directly maps product specifications, mold combinations, and storage location numbers, simplifying intermediate processes, avoiding human error, and further ensuring the matching degree between molds and product specifications, improving production quality and efficiency. The dual verification mechanism re-verifies after mold selection to ensure that mold specifications and technical requirement numbers are correct, effectively preventing the risk of incorrect mold selection, avoiding potential quality problems in the production process, and significantly improving product qualification rate and production efficiency. Attached Figure Description
[0016] Figure 1 This is a schematic diagram of the process in the efficient internal thread mold matching method of the present invention. Detailed Implementation
[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0018] This invention discloses an efficient method for matching internal thread dies, aiming to achieve rapid matching and efficient production of internal thread dies by constructing a complete digital management system. It integrates multi-dimensional information such as die, process, product specifications, and inventory management, and achieves automated and precise die configuration through an intelligent matching system, including the following steps: Step one involves establishing a detailed geometric dimension parameter database for all tooling and dies involved in the production of internal thread products, including reducing dies, thread mandrels, sliding mandrels, mandrels, spinning rings, steel balls, pre-sizing dies, and sizing dies. This database not only records the basic specifications of each die but also covers its application conditions and limitations in actual production, ensuring that die selection is highly scientific and applicable. The database is equipped with a dynamic maintenance mechanism, allowing die management personnel to update information on new die specifications in a timely manner based on production needs, thereby ensuring the database's real-time performance and completeness.
[0019] Step two involves building a database of tooling and mold dimensions for each product specification based on the manufacturing process of internal thread products. This database precisely matches each product specification with its required complete mold combination, allowing operators to quickly obtain the dimensions of the entire mold set simply by inputting the product specification. This design not only greatly simplifies the mold search process but also provides data support for mold replacement and process adjustments during production. When new product specifications or process improvements occur, the database can be updated by designated personnel, ensuring consistency between the database and the manufacturing process, and guaranteeing its accuracy and reliability. The continuous update mechanism of the database ensures that new product specifications and process changes are quickly reflected in the system, ensuring that the database remains highly consistent with actual production needs. Each product specification requires a set of tooling and molds for processing. A set of tooling and molds includes a reducing die, threaded mandrel, sliding mandrel, mandrel rod, spinning ring, steel ball, pre-diameter die, and sizing die; a set of molds can be considered a combined block.
[0020] Step three involves establishing a detailed product specification database for each type of internal thread product, along with its corresponding technical requirements, tolerance ranges, and technical requirement numbers. Product specifications include key parameters such as outer diameter, tooth height, bottom wall thickness, and helix angle. Technical requirements tolerance ranges include the tolerance requirements for parameters such as outer diameter, tooth height, bottom wall thickness, helix angle, tooth tip angle, and per-unit weight. Each technical requirement number corresponds to a unique number for each customer and each specification. This database assigns a unique technical requirement number to each product specification, facilitating rapid identification and traceability during production. The database's real-time update function ensures that the technical requirements of new customers and new product specifications are promptly incorporated into the system, providing comprehensive data support for accurate mold matching. New customers or new specifications can be updated in the database by designated personnel.
[0021] Step four involves building a detailed inventory database for all tooling and molds used in the production of internal thread products, based on their type and specifications. This database accurately records the storage location and quantity of each mold, making mold management more organized. Through close integration with the procurement and requisition processes, the database can reflect the real-time inventory dynamics of molds, providing a basis for mold allocation and replenishment decisions. The data is updated whenever a new mold is purchased or issued for use.
[0022] Step five involves linking and deeply integrating the aforementioned databases through a program to form a rapid matching MES system for internal thread molds. This system, as the core driver of the entire method, achieves efficient data linkage and intelligent analysis, providing solid technical support for rapid mold matching.
[0023] Step five: When the required tooling and molds are needed to produce internal thread products of a specific specification, the operator only needs to enter the corresponding product technical requirement number (i.e., a unique number corresponding to each customer and each specification) into the quick-match system. The system then quickly retrieves and matches all the tooling and molds required to produce the product based on the number, while accurately locating the storage location number of each mold. This process greatly shortens the mold search time and improves production preparation efficiency.
[0024] Step six: Based on the storage location number provided by the system, the operator goes to the designated location to select and retrieve the required tooling molds. This step is designed with the actual operational needs of the production site in mind, making the mold retrieval process simple, clear, efficient, and orderly.
[0025] Step seven: After the mold selection is completed, the quick-match system verifies the product specifications, technical requirement numbers, and the tooling molds to be used again. This dual verification mechanism ensures a high degree of matching between the mold and the production task, effectively avoiding production errors caused by incorrect mold selection, and providing strong assurance for product quality.
[0026] Through close collaboration in the above steps, the efficient internal thread mold matching method disclosed in this embodiment of the invention achieves a full-process digital and intelligent transformation from mold management to production application, significantly improving mold matching efficiency and production flexibility. Through precise data control and intelligent system support, it greatly reduces production costs, enhances the market competitiveness of enterprises, and contributes to the efficient production of internal thread products.
[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
