Problem to Be Overcome By the Invention
However, Patent Document 1 does not disclose contents of the manufacturing history data stored and managed for every management number in the above-described managing method. Further, the cast-iron pipes are centrifugally cast by pouring molten metal into an interior of a metal mold rotated at high speeds. This metal mold is not collapsed like a sand mold at a demolding step where a cast product is taken out but is used repeatedly. More specifically, cast-iron pipes having the same shape are manufactured using the same metal mold. Accordingly, the metal mold used in the casting does not differ for every one cast-iron pipe. Further, since the metal mold is present even after completion of the cast-iron pipes, the metal mold can be inspected when a defect occurs in the quality of the iron-cost pipes. Thus, this managing method is poor in the utility to store and manage data relating the metal mold for every one of cast-iron pipes.
On the other hand, the sand mold is collapsed in demolding when cast products are cast using a sand mold. Accordingly, no sand mold is present after completion of the cast products with the result that the sand mold cannot be inspected. Further, intermediates in the manufacturing process of cast products include what is hard to inspect after completion of cast products (for example, molten metal, a core and the like) as well as the sand mold.
The present invention was made in view of the foregoing circumstances and an object thereof is to provide a method of managing manufacturing data of cast products, which can allow inspection of the intermediates which affect the quality of cast products and are hard to inspect after completion of the cast products.
Means for Overcoming the Problem
A method of managing manufacturing data of cast products according to the present invention, in which various manufacturing data of cast products are registered on a database and managed, includes a first data acquisition step of acquiring manufacturing data of a sand mold in a mold making process of making sand molds, and a second data acquisition step of acquiring manufacturing data of molten metal in a molten-metal making process in which casting metals are melted to make molten metal and the molten metal is tapped off. The manufacturing data acquired in the first and second data acquisition steps are registered on the database and managed while being correlated with every one of the corresponding cast products.
A sand mold and molten metal are intermediates in a manufacturing process of cast products. States of the sand mold and the molten metal have a major effect on the quality of cast product. However, the sand mold is collapsed during demolding. Accordingly, the sand mold cannot directly be inspected after completion of a cast product. Further, the molten metal cannot directly be inspected after completion of the cast product, either. In view of the circumstances, in this method of managing manufacturing data of cast products, the manufacturing data of sand mold in the mold making process acquired in the first data acquisition step and the manufacturing data of molten metal in the molten-metal making process acquired in the second data acquisition step are registered on the database and managed while being correlated with every one of the corresponding cast products. Consequently, the sand mold and the molten metal used in the manufacture of the cast product can be inspected on the basis of the various manufacturing data registered on the database even after completion of the cast product. In the invention, “correlated” refers to the state where the various manufacturing data can be specified on the basis of the cast product by accessing the database and the state where the cast product can be specified on the basis of the various manufacturing data.
Accordingly, the intermediates in the manufacturing process, which affects the quality of cast product and is hard to inspect after completion of the cast product, can be inspected in the method of managing manufacturing data of cast products according to the invention.

Mode for Carrying Out the Invention
An embodiment of the method of managing manufacturing data of cast products, according to the present invention will be described with reference to the drawings.
Various manufacturing data are registered on a database 1 of a manufacturing data management system and managed by the method of managing manufacturing data of cast products, according to the embodiment, as shown in Fig. 1. The various manufacturing data are registered on the database 1 by automatic input from various measuring devices and sensors or by manual input by an operator using a touch panel in a manufacturing process of cast products. The database 1 is accessible via a network from a plurality of computers 2.
The manufacturing process of the cast products includes a mold making process 10, a core making process 20, a molten-metal making process 30, a pouring process 40, a forming process 50, a demolding process 60 and a finishing process 70, as shown in Fig. 2.
A sand mold 11 (see Fig. 4(C)) is made in the mold making process 10.
The sand mold 11 is an intermediate in a manufacturing process of cast products.
The mold making process 10 includes a kneading step, a sand placing step, a hardening step, a pattern extracting step, a core setting step and a mating step, all of which are carried out in this order. The molding sand 13 to which resin and a hardener are added is kneaded in the kneading step. In the sand placing step, the kneaded molding sand 13 is put into a molding flask 12 comprising two casting patterns (not shown) which have the same shape and are placed in parallel. The molding sand 13 put into the molding flask 12 is hardened in the hardening step.
The casting patterns are extracted from the molding flask 12 in the pattern extracting step. An upper mold 11A and a lower mold 11B are thus formed (see Fig. 4(A)). The upper mold 11A is formed with two cavities 14A having the same shape and placed in parallel, and the lower mold 11B is formed with two cavities 14B having the same shape and placed in parallel. The upper mold 11A has a pouring gate 15 and a degassing hole (not shown) both of which are formed therethrough and communicate with the cavities 14A. Cores 21 made in the core making process 20 which will be described later are disposed in the two cavities 14B of the lower mold 11B respectively (see Fig. 4(B)). In the mating step, the upper mold 11A is combined with the lower mold 11B in which the cores 21 are disposed (see
Fig. 4(C)). Thus, a sand mold 11 is completed in which the cores 21 are disposed in the cavities 14A and 14B respectively. Two castings can be cast by the use of the single sand mold 11.
In the mold making process 10, a mold-making serial number (ZB-1, ZB-2, ...) is assigned to every one of sand molds 11 or more specifically, every one set of combined upper and lower molds 11A and 11B at the pattern extracting step, as shown in Fig. 3(B). In other words, the mold-making serial numbers are registered ;
on the database 1 and managed as shown in Fig. 1. In this case, manufacturing data of every one of sand molds 11 acquired in a first data acquisition step before the pattern extracting step is registered on the database 1 in association with the mold-making serial number.
In the first data acquisition step, additive amounts of resin and hardener added to the molding sand 13, a temperature of kneading sand at the kneading step, the number of times of use of casting pattern, a hardening time of the molding sand 13 and the like are automatically acquired using measuring devices and sensors for every one of sand molds 11 (every one of sets of the upper and lower molds 11A and 11B) in the mold-making process 10. Furthermore, the first data acquisition step acquires matters the operator has found by manual input on the touch panel, in a core setting step. Data input in this case includes pieces of information that the core 21 is tight in the cavity 14B or that the core has broken, or the like. Since the core setting step is carried out after the pattern extracting step, the data manually input in the core setting step is registered on the database 1 in association with the mold-making serial number.
Further, in the mold-making process 10, every one of products to be cast is assigned with a corresponding product serial number (CB-1, CB-2, ...) in the core setting step, as shown in Fig. 3(B). More specifically, the product serial numbers are registered on the database 1 and managed, as shown in Fig. 1. No cast product is present at this time. Accordingly, the product serial number is assigned to every one of sets of cavities 14A and 14B in which one casting is to be formed.
The product serial number is attached to a cavity surface of a predetermined portion of the upper mold 11A or the lower mold 11B. As a result, the product serial number is formed as embossed letter on every cast product.
Further, in the core setting step, as shown in Fig. 5, the product serial numbers, the mold-making serial numbers and core serial numbers which will be described later are registered on the database 1 in association with one another ;
and are managed. Thus, in the core setting step, the product serial numbers, the mold-making serial numbers and the core serial numbers are registered on the database 1 being associated with one another, so that various manufacturing data of the sand mold 11 and the core 21 can reliably be correlated with every one of cast products.
The cores 21 are manufactured in the core making process 20. The cores 21 are also intermediates in the manufacturing process of cast products. The core making process 20 includes a sintering step, a deburring step, an assembly step, a coating/drying step and an inspection step all of which are carried out in this order. In the sintering step, the molding sand 13 is kneaded with the resin and the hardener being added thereto and then put into a metal mold to be formed into a predetermined shape (an intermediate of the core 21), thereafter being sintered.
The intermediate of the core 21 is deburred in the deburring step. A plurality of intermediates having different shapes is assembled into the core 21 in the assembly step. A heat-resistant coating agent is applied to the core 21 and dried in the coating/drying step. The operator carries out a visual inspection of the cores 21 in the inspection step. Thus, the cores 21 to be disposed in the cavities of the sand mold 11 are completed. in the core making process 20, a core serial number (N-1, N-2, ...) is assigned to every one of cores 21 in the sintering step as shown in Fig. 3(A). The core serial numbers are registered on the database 1 and managed as shown in
Fig. 1. In this case, the sintering temperature of every one of cores 21 is acquired in a third data acquisition step and registered on the database 1 in association with the core serial number. Further, a tape on which the core serial number is marked is affixed to every core 21.
In the third data acquisition step, the sintering temperature in the sintering step, a coating concentration in the coating/drying step, a drying temperature in the coating/drying step and the like are automatically acquired using measuring devices and sensors for every one of cores 21 in the core making process 20. The coating concentration refers to a concentration (a variance) of a muddy coating agent applied to the cores 21. Furthermore, the third data acquisition step acquires matters the operator has found, by manual input on the touch panel, in the inspection step of the core making process 20. Since the coating/drying step and the inspection step are carried out after the deburring step, various data acquired in these steps are registered on the database in association with the corresponding core serial numbers when the data are acquired.
Molten metal to be poured into the cavities of the sand mold 11 is manufactured in the molten-metal making process 30. The molten metal is also an intermediate in the manufacturing process of cast products. The molten-metal making process 30 includes a measuring step, a melting step, a component regulating step and a tapping step all of which are carried out in this order as shown in Fig. 2. In the measuring step, amounts of various casting metals to be melted at one time in an electric furnace, additives and the like are measured in the measuring step. The various casting metals and the like are melted by the electric furnace in the melting step. The components of the molten metal in the electric furnace are regulated in the component regulating step. The molten metal in the electric furnace is tapped off into a treating ladle in three times.
In the molten-metal making process 30, a melting serial number (S-1-1,
S-1-2, $-1-3, S-2-2, S-2-3, ...) is assigned in the tapping step as shown in Fig. 3(C). More specifically, the melting serial numbers are registered on the database 1 and managed. In this case, the manufacturing data of molten metal of every tapped molten metal acquired in the second data acquisition step is registered on the database 1 in association with the melting serial number. The melting serial number is assigned to every amount of molten metal melted in one time in the electric furnace as S-1, 8-2, ..., and a sub-number (-1, -2, -3) is added thereto every time the molten metal is tapped off into the treating ladle in three times.
A temperature of molten metal in the electric furnace, weight of molten metal, blending amounts of various casting metals, blending amounts of additives, component values and the like are automatically acquired for every tapped molten metal using measuring devices and sensors in the second data acquisition step in the molten-metal making process 30. Furthermore, matters the operator has found are acquired by manual input on the touch panel at the tapping step in the second acquisition step.
In the pouring process 40, the molten metal made in the molten-metal making process 30 is poured into the sand mold 11 completed through the mold making process 10, as shown in Fig. 2. More specifically, the molten metal is transferred from the treating ladle to a pouring ladle, and the molten metal in the pouring ladle is caused to flow from a pouring gate of the sand mold 11 into the cavity. In this case, the molten metal in the pouring ladle is poured into three sand molds 11. In the pouring process 40, the mold-making serial numbers and the melting serial numbers are registered on the database 1 in association with each other and managed, as shown in Fig. 5. As a result, the product serial numbers, the mold-making serial numbers, the core serial numbers and the melting serial numbers are associated with one another on the database 1. Thus, in the pouring process 40, the mold-making serial numbers and the melting serial numbers are registered on the database 1 being associated with each other, so that manufacturing data of the molten metal can reliably be correlated with every one of cast products.
In the forming process 50, the molten metal poured into the sand mold 11 is gradually cooled (slow-cooled) thereby to be solidified. As a result, castings are formed in the sand mold 11. In this case, a time period required for cooling is automatically acquired using measuring devices and sensors and registered on the database 1 in association with the mold-making serial numbers.
In the demolding process 60, the castings are taken out of the sand mold
11. The demolding process 60 includes a demolding step, an external slow-cooling step, an external shot blasting step and a primary inspection step, all of which are carried out in this order. In the demolding step, the sand mold 11 is collapsed in order to take out the castings. The castings taken out of the sand mold 11 are slow-cooled in the external slow-cooling step. The molding sand 13 adhered to outer surfaces of the castings are removed by shot blasting in the external shot blasting step. The operator carries out a visual inspection of the outer surfaces of the castings in the primary inspection step. In this case, matters the operator has found are manually input on the touch panel to be registered on the database 1 in association with the product serial numbers.
In the finishing process 70, the castings are finished into cast products, which are shipped. The finishing process 70 includes a deburring step, an internal shot blasting step, a secondary inspection step and a fraise step, all of which are carried out in this order. Burrs formed on the castings are removed in the deburring step. The molding sand 13 adhered to inner surfaces of the castings are removed by shot blasting in the internal shot blasting step. The operator carries out a final visual inspection of the castings in the secondary inspection step. In this case, matters the operator has found are manually input on the touch panel to be registered on the database 1 in association with the product serial numbers.
Predetermined portions of the castings are cut in the fraise step. The cast products are thus completed to be shipped.
In the method of managing manufacturing data of cast products, the product serial numbers, the mold-making serial numbers, the core serial numbers and the melting serial numbers are associated with one another on the database 1.
This correlates various manufacturing data of the cast products with every corresponding cast product. The manufacturing data includes the manufacturing data of every sand mold 11 in the mold-making process 10 acquired in the first data acquisition step, the manufacturing data of molten metal for every tapped molten metal in the molten-metal making process 30 acquired in the second data acquisition step, manufacturing data of every core 21 in the core making process 20 acquired in the third data acquisition step and the like.
Accordingly, the manufacturing data of the cast product can be called up on the basis of the product serial number assigned to the cast product using the computer 2 accessible to the data- base 1 via the network even after completion of the cast product. Consequently, the sand mold 11, molten metal and core 21 used in the manufacture of the cast product can be inspected. Further, the product serial number can be called up on the basis of the core serial number, mold-making serial number and melting serial number using the computer 2 accessible to the data base 1 via the network. As a result, even when the manufacturing is continued in the situation that failure would occur in one step, the corresponding cast products can be specified.
Accordingly, the manufacturing data managing method of the foregoing embodiment can inspect the intermediates which affect the quality of the cast product and belong to the manufacturing step hard to inspect after completion of the cast product.
Further, according to the manufacturing data managing method of the foregoing embodiment, the manufacturing data is acquired for every one of sand molds 11, the manufacturing data of molten metal is acquired for every tapped molten metal and the manufacturing data is acquired for every one of cores 21, and these manufacturing data are correlated with every one of cast products.
Accordingly, various manufacturing data inherent in every one of cast products but not in every lot of cast products can be specified. Consequently, factors affecting the quality of cast product can accurately be understood.
Further, in this manufacturing data managing method, various serial numbers are assigned and associated with one another for every one of cast products. As a result, the manufacturing data can easily be correlated with every one of cast products.
The invention should not be limited by the foregoing embodiment described with reference to the drawings but the technical scope of the invention encompasses the following embodiments: (1) Although the manufacturing data managing method has been described regarding the cast products cast with the cores being disposed in the cavities in the foregoing embodiment, the method may be applied to cast products cast without use of cores. (2) Manufacturing data other than those presented in the foregoing embodiment may be registered on the database and managed. (3) Although two castings are cast in one sand mold in the foregoing embodiment, one, three or more castings may be cast in one sand mold. (4) Although the molten metal in the electric furnace is tapped off into the pouring ladle in three times in the foregoing embodiment, the molten metal may be tapped off into the pouring ladle in a plurality of times other than three times. (5) Timings to assign the serial numbers may differ from those described above in the foregoing embodiment. (6) The serial numbers may have a form other than that shown in the foregoing embodiment.
