[0047] A manufacturing method for a steel skeleton electrofusion pipe fitting proposed in an embodiment of the present application. The pipe fitting includes an injection molding bonding section and pipe fitting prefabricated ends. The pipe fitting prefabricated ends are installed at both ends of the injection molding bonding section. The injection molding bonding section includes a steel skeleton and an injection molding reinforcement layer. The method includes: first, obtaining the manufacturing task information of the target pipe fitting. The manufacturing task information includes the length dimension information, cross-sectional dimension information, material information, and standard information of the target pipe fitting. Then, based on the cross-sectional dimension information and standard information of the target pipe fitting, select the pipe fitting prefabricated ends of the target pipe fitting. Then, based on the cross-sectional dimension information and length dimension information of the target pipe fitting, select the steel skeleton of the target pipe fitting. Then, control the pipe fitting prefabricated ends of the two target pipe fittings to be installed at both ends of the steel skeleton of the target pipe fitting respectively. Then, based on the material information and standard information of the target pipe fitting, select the injection molding material of the target pipe fitting. Then, control the injection molding material of the target pipe fitting to be injection molded on the steel skeleton of the target pipe fitting to form the injection molding reinforcement layer of the target pipe fitting. Finally, manufacture the target pipe fitting based on the injection molding reinforcement layer, steel skeleton, and pipe fitting prefabricated ends of the target pipe fitting.

[0048] That is, when manufacturing the target pipe fitting, first, according to the cross-sectional dimension information and standard information in the target pipe fitting task information, obtain the pipe fitting prefabricated ends of the target pipe fitting. At the same time, according to the cross-sectional dimension information and length dimension information of the target pipe fitting, select the steel skeleton of the target pipe fitting. Then, install the two selected pipe fitting prefabricated ends at both ends of the steel skeleton. Next, according to the material information and standard information of the target pipe fitting, select the injection molding material of the target pipe fitting. Then, inject the injection molding material onto the steel skeleton of the target pipe fitting to form the injection molding reinforcement layer of the target pipe fitting. Finally, manufacture the target pipe fitting according to the injection molding reinforcement layer, steel skeleton, and pipe fitting prefabricated ends of the target pipe fitting.

[0049] That is, since this method can automatically select the pipe fitting prefabricated ends, steel skeleton, and injection molding material of the target pipe fitting respectively according to the manufacturing task information of the target pipe fitting, then connect the mutually matching pipe fitting prefabricated ends and the steel skeleton, and then inject the injection molding material onto the steel skeleton, and finally manufacture the target pipe fitting. Therefore, compared with the prior art in which the pipe fitting prefabricated ends, steel skeleton, and injection molding material of the target pipe fitting are manually selected, this method can select the pipe fitting prefabricated ends, steel skeleton, and injection molding material of the target pipe fitting more efficiently. And by prefabricating the pipe fitting prefabricated ends in advance and then injection molding the steel skeleton and the pipe fitting prefabricated ends together instead of performing integral injection molding, the manufacturing efficiency of the target pipe fitting can be greatly improved.

[0062] It should be understood that the specific embodiments described herein are only used to explain this application and are not used to limit this application.

[0063] Currently, the steel - skeleton electro - fusion pipe fitting is integrally injection - molded by injection molding. However, this method of integral injection molding has low efficiency.

[0064] To solve the above - mentioned technical problems, this application provides a method for manufacturing a steel - skeleton electro - fusion pipe fitting. As Figures 1-4 shown, the pipe fitting includes an injection - molding bonding section and a pre - fabricated end 1 of the pipe fitting. The pre - fabricated end 1 of the pipe fitting is installed at both ends of the injection - molding bonding section. The injection - molding bonding section includes a steel skeleton 3 and an injection - molding reinforcement layer. As Figure 5 shown, the method includes:

[0065] S11: Obtain the manufacturing task information of the target pipe fitting; the manufacturing task information includes the length dimension information, cross-sectional dimension information, material information, and standard information of the target pipe fitting.

[0066] In the specific implementation process, the target pipe fitting refers to the pipe fitting with a steel skeleton 3 that needs to be manufactured, and the manufacturing task information refers to the task information issued by the corresponding unit according to the production demand or supply demand. This task information mainly makes corresponding requirements for the performance, indicators, etc. of the target pipe fitting, such as length dimension information, cross-sectional dimension information, material information, standard information, and the number of pieces in this batch. Among them, the standard information refers to the information required to meet a certain standard.

[0067] S12: Based on the cross-sectional dimension information and standard information of the target pipe fitting, select the prefabricated end of the target pipe fitting.

[0068] In the specific implementation process, since the prefabricated end 1 of the target pipe fitting is prefabricated in advance, it is necessary to select the prefabricated end 1 that matches the manufacturing task information of the target pipe fitting. The information that affects the selection of the prefabricated end 1 is mainly the cross-sectional dimension information and standard information of the target pipe fitting. Therefore, according to the cross-sectional dimension information of the target pipe fitting, the cross-sectional dimensions of the prefabricated end 1 can be selected, such as the cross-sectional shape, area, perimeter, etc. of the prefabricated end 1; according to the standard information of the target pipe fitting, the prefabricated end 1 that meets the requirements of the target pipe fitting, such as quality requirements, can be selected. Thus, based on the cross-sectional dimension information and standard information of the target pipe fitting, the prefabricated end 1 of the target pipe fitting can be quickly selected.

[0069] S13: Based on the cross-sectional dimension information and length dimension information of the target pipe fitting, select the steel skeleton of the target pipe fitting.

[0070] In the specific implementation process, since the steel skeleton 3 of the target pipe fitting is also manufactured in advance, it is also necessary to select the steel skeleton 3 that matches the manufacturing task information of the target pipe fitting. The information that affects the selection of the steel skeleton 3 is mainly the cross-sectional dimension information and length dimension information of the target pipe fitting. Therefore, according to the cross-sectional dimension information of the target pipe fitting, the diameter of the steel skeleton 3 can be selected, and according to the length dimension information of the target pipe fitting, the length of the steel skeleton 3 can be selected. Thus, based on the cross-sectional dimension information and length dimension information of the target pipe fitting, the steel skeleton 3 of the target pipe fitting can be quickly selected.

[0071] S14: Control the prefabricated ends of the two target pipe fittings to be respectively installed at both ends of the steel skeleton of the target pipe fitting.

[0072] In the specific implementation process, based on the two pipe fitting prefabricated ends 1 of the target pipe fitting selected in step S12 and step S13 and one steel skeleton 3 (a batch of pipe fitting prefabricated ends 1 and steel skeletons 3 that meet the requirements can also be selected simultaneously), at this time, relevant equipment can be controlled to install the pipe fitting prefabricated ends 1 at both ends of the steel skeleton 3, and thus the basic skeleton of the target pipe fitting can be built.

[0073] S15: Based on the material information and standard information of the target pipe fitting, select the injection molding material for the target pipe fitting.

[0074] In the specific implementation process, after the pipe fitting prefabricated ends 1 of the target pipe fitting are respectively installed at both ends of the steel skeleton 3, that is, after the basic skeleton of the target pipe fitting is built, it is necessary to inject the corresponding injection molding material onto the steel skeleton 3. To inject the corresponding injection molding material onto the steel skeleton 3, it is necessary to select the injection molding material corresponding to the target pipe fitting. The main factors affecting the selection of the injection molding material for the target pipe fitting are the material information and standard information of the target pipe fitting. Through the material information and standard information of the target pipe fitting, the injection molding material that meets the corresponding requirements can be selected.

[0075] S16: Control the injection of the injection molding material of the target pipe fitting onto the steel skeleton of the target pipe fitting to form an injection molding reinforcement layer of the target pipe fitting.

[0076] In the specific implementation process, after the injection molding material of the target pipe fitting is selected, the steel skeleton 3 and the pipe fitting prefabricated end 1 can be placed as a whole into a molding die, and then the injection molding material is injected onto the steel skeleton 3 of the target pipe fitting in a conventional manner. When the injection molding material dries, the injection molding reinforcement layer of the target pipe fitting can be formed.

[0077] S17: Manufacture the target pipe fitting based on the injection molding reinforcement layer, steel skeleton, and pipe fitting prefabricated end of the target pipe fitting.

[0078] In the specific implementation process, after the injection molding reinforcement layer is formed on the steel skeleton 3, subsequent steps such as pressure maintaining and shaping, deburring, wire laying, and installing terminal posts on the pipe fitting prefabricated end 1 can be carried out based on the injection molding reinforcement layer, steel skeleton 3, and pipe fitting prefabricated end 1 of the target pipe fitting. In this way, the target pipe fitting that meets the relevant requirements can be manufactured.

[0079] In this embodiment, when manufacturing a target pipe fitting, first, according to the cross-sectional dimension information and standard information in the target pipe fitting task information, the pipe fitting prefabricated end 1 of the target pipe fitting is obtained. At the same time, according to the cross-sectional dimension information and length dimension information of the target pipe fitting, the steel skeleton 3 of the target pipe fitting is selected. Then, the two selected pipe fitting prefabricated ends 1 are installed at both ends of the steel skeleton 3. Next, according to the material information and standard information of the target pipe fitting, the injection molding material of the target pipe fitting is selected, and then the injection molding material is injection molded onto the steel skeleton 3 of the target pipe fitting to form the injection molding reinforcement layer of the target pipe fitting. Finally, the target pipe fitting is manufactured based on the injection molding reinforcement layer, the steel skeleton 3, and the pipe fitting prefabricated end 1 of the target pipe fitting.

[0080] That is, since this method can automatically select the pipe fitting prefabricated end 1, the steel skeleton 3, and the injection molding material of the target pipe fitting respectively according to the manufacturing task information of the target pipe fitting, then connect the mutually matching pipe fitting prefabricated end 1 and the steel skeleton 3, and then injection mold the injection molding material onto the steel skeleton 3, and finally manufacture the target pipe fitting. Therefore, compared with the prior art in which the pipe fitting prefabricated end 1, the steel skeleton 3, and the injection molding material of the target pipe fitting are manually selected, this method can more efficiently select the pipe fitting prefabricated end 1, the steel skeleton 3, and the injection molding material of the target pipe fitting, and by prefabricating the pipe fitting prefabricated end 1 in advance and then injection molding the steel skeleton 3 and the pipe fitting prefabricated end 1 together instead of performing integral injection molding, the manufacturing efficiency of the target pipe fitting can be greatly improved.

[0081] In some embodiments, such as Figure 6 shown, before the step of selecting the pipe fitting prefabricated end of the target pipe fitting based on the cross-sectional dimension information and standard information of the target pipe fitting, it further includes:

[0082] S21: Obtain the cross-sectional dimension information, standard information, and pipe fitting prefabricated ends of a number of historical pipe fittings.

[0083] In the specific implementation process, the historical pipe fitting refers to a pipe fitting of the same type as the target pipe fitting and before the production of the target pipe fitting. In this embodiment, based on the relevant information of the historical pipe fitting, the pipe fitting prefabricated end 1 of the target pipe fitting is selected. Therefore, the relevant information of the historical pipe fitting is obtained first, such as the cross-sectional dimension information, standard information, and pipe fitting prefabricated end 1 of the historical pipe fitting, etc.

[0084] S22: Based on the cross-sectional dimension information, standard information, and pipe fitting prefabricated ends of a number of the historical pipe fittings, obtain the one-to-one correspondence between the cross-sectional dimension information of the historical pipe fitting and the pipe fitting prefabricated end of the historical pipe fitting, and obtain the one-to-one correspondence between the standard information of the historical pipe fitting and the pipe fitting prefabricated end of the historical pipe fitting.

[0085] In the specific implementation process, after obtaining the cross-sectional dimension information, standard information of the historical pipe fitting, and the pipe fitting prefabricated end 1, based on the idea of selecting the pipe fitting prefabricated end 1 of the target pipe fitting according to the cross-sectional dimension information and standard information of the target pipe fitting, the corresponding pipe fitting prefabricated end 1 can still be selected according to the cross-sectional dimension information and standard information of the historical pipe fitting. In this way, a one-to-one correspondence is formed between the standard information of the historical pipe fitting and the pipe fitting prefabricated end 1 of the historical pipe fitting.

[0086] S23: Based on the one-to-one correspondence between the cross-sectional dimension information of the historical pipe fitting and the pipe fitting prefabricated end of the historical pipe fitting, and the one-to-one correspondence between the standard information of the historical pipe fitting and the pipe fitting prefabricated end of the historical pipe fitting, select the pipe fitting prefabricated end of the historical pipe fitting.

[0087] In the specific implementation process, since both the cross-sectional dimension information and the standard information of the historical pipe fitting will affect the pipe fitting prefabricated end 1 of the historical pipe fitting, therefore, the influence degrees of the cross-sectional dimension information and the standard information of the historical pipe fitting on the selection of the pipe fitting prefabricated end 1 of the historical pipe fitting are studied separately. Specifically, based on the one-to-one correspondence between the cross-sectional dimension information of the historical pipe fitting and the pipe fitting prefabricated end 1 of the historical pipe fitting, a cross-sectional dimension information score is obtained; based on the one-to-one correspondence between the standard information of the historical pipe fitting and the pipe fitting prefabricated end 1 of the historical pipe fitting, a standard information score is obtained; based on the cross-sectional dimension information score and the standard information score, the pipe fitting prefabricated end 1 of the historical pipe fitting is selected. More specifically, if the cross-sectional dimension information score is greater than the standard information score, select the pipe fitting prefabricated end 1 corresponding to the cross-sectional dimension information of the historical pipe fitting as the pipe fitting prefabricated end 1 of the historical pipe fitting; if the cross-sectional dimension information score is less than the standard information score, select the pipe fitting prefabricated end 1 corresponding to the standard information of the historical pipe fitting as the pipe fitting prefabricated end 1 of the historical pipe fitting. Therefore, based on the cross-sectional dimension information and standard information of the target pipe fitting, the pipe fitting prefabricated end 1 of the historical pipe fitting can be selected according to the above method; since the historical pipe fitting and the target pipe fitting belong to the same type of pipe fitting, the influencing factors on the pipe fitting prefabricated end 1 of the historical pipe fitting and the pipe fitting prefabricated end 1 of the target pipe fitting are the same. Therefore, based on the selected pipe fitting prefabricated end 1 of the historical pipe fitting, the pipe fitting prefabricated end 1 of the target pipe fitting can be selected, that is, select the pipe fitting prefabricated end 1 of the historical pipe fitting as the pipe fitting prefabricated end 1 of the target pipe fitting.

[0088] In this embodiment, through the above technical solution, the influence degrees of the cross-sectional dimension information and the standard information of the historical pipe fitting on the selection of the pipe fitting prefabricated end 1 of the historical pipe fitting can be analyzed more specifically, that is, the amounts of the cross-sectional dimension information score and the standard information score, to determine which pipe fitting prefabricated end 1 is selected as the pipe fitting prefabricated end 1 of the historical pipe fitting, and then use the selected pipe fitting prefabricated end 1 of the historical pipe fitting as the pipe fitting prefabricated end 1 of the target pipe fitting, so that the pipe fitting prefabricated end 1 of the target pipe fitting can be selected more accurately and efficiently.

[0089] In some embodiments, such as Figure 7 shown, before the step of selecting the steel skeleton 3 of the target pipe fitting based on the cross-sectional dimension information and the length dimension information of the target pipe fitting, the following steps are further included

[0090] S31: Obtain the cross-sectional dimension information, the length dimension information, and the steel skeleton of a number of historical pipe fittings.

[0091] In the specific implementation process, similarly, the steel skeleton 3 is also a pre-manufactured component, so it can also be quickly selected through the information of historical pipe fittings. Among them, the information of historical pipe fittings includes the cross-sectional dimension information, the length dimension information, and the steel skeleton 3 of historical pipe fittings.

[0092] S32: Based on the cross-sectional dimension information, the length dimension information, and the steel skeleton of the historical pipe fittings, obtain the one-to-one correspondence between the cross-sectional dimension information, the length dimension information of the historical pipe fittings and the steel skeleton of the historical pipe fittings.

[0093] In the specific implementation process, similar to the target pipe fitting, according to the cross-sectional dimension information of the historical pipe fitting, the diameter of the steel skeleton 3 of the historical pipe fitting can also be selected, and according to the length dimension information of the historical pipe fitting, the length of the steel skeleton 3 of the historical pipe fitting can also be selected, and the one-to-one correspondence between the cross-sectional dimension information, the length dimension information of the historical pipe fitting and the steel skeleton 3 of the historical pipe fitting is obtained.

[0094] S33: Based on the one-to-one correspondence between the cross-sectional dimension information, the length dimension information of the historical pipe fittings and the steel skeleton of the historical pipe fittings, select the steel skeleton of the historical pipe fittings.

[0095] In the specific implementation process, according to the one-to-one correspondence between the cross-sectional dimension information, the length dimension information of the historical pipe fitting and the steel skeleton 3 of the historical pipe fitting obtained in step S32, knowing the cross-sectional dimension information and the length dimension information of the historical pipe fitting can select the corresponding steel skeleton 3 of the historical pipe fitting. Based on the obtained steel skeleton 3 of the historical pipe fitting, the steel skeleton 3 of the target pipe fitting can be selected, that is, select the steel skeleton 3 that is the same as the steel skeleton 3 of the historical pipe fitting as the steel skeleton 3 of the target pipe fitting. In this way, the steel skeleton 3 of the historical pipe fitting can be selected more quickly and efficiently.

[0096] In some embodiments, such as Figures 8-9 shown, a card slot 2 is opened on the side surface of the pipe fitting prefabricated end 1, a plurality of strengthening holes 31 are opened on the steel skeleton 3, and a hole net cover 5 is arranged on the strengthening holes 31; the installation of the pipe fitting prefabricated ends 1 of the two target pipe fittings at both ends of the steel skeleton 3 of the target pipe fitting respectively includes:

[0097] The control reinforcement 4 passes through the reinforcing holes 31 and the card slots 2 in sequence, so as to respectively install the prefabricated ends 1 of the two target pipe fittings at both ends of the steel skeleton 3 of the target pipe fitting.

[0098] In this embodiment, the traditional embedded steel skeleton 3 is a porous mesh structure, that is, a plurality of reinforcing holes 31 are formed in the steel skeleton 3, making the product not easy to delaminate. However, there are weak areas in its strength. After injection molding, the perforation gaps of the internal steel skeleton 3 cannot be well protected by the steel skeleton 3, and the radial stress is relatively large under the internal high-pressure environment. Therefore, a hole mesh cover 5 is designed in the perforation area of the steel skeleton 3, which helps to enhance the radial pressure resistance of the pipe fitting. The hole mesh cover 5 of the steel skeleton 3 is connected to the main body of the steel skeleton 3 and designed with a die-piercing pore, which does not affect the integrity between the steel skeleton 3 and the pipe fitting plastic part, and the overall manufacturing process remains unchanged. The reinforcement 4 is a component connecting the prefabricated ends 1 of the two pipe fittings and the steel skeleton 3, such as a steel bar, etc. Passing the reinforcement 4 through the reinforcing holes 31 and the card slots 2 in sequence can connect the prefabricated ends 1 of the pipe fittings to both ends of the steel skeleton 3. In this way, by opening card slots 2 on the side of the prefabricated ends 1 of the pipe fittings, the prefabricated ends 1 of the pipe fittings and the steel skeleton 3 can be connected more conveniently.

[0099] In some embodiments, such as Figure 10 shown, before the step of selecting the injection molding material of the target pipe fitting based on the material information and standard information of the target pipe fitting, it further includes:

[0100] S41: Obtain the material information, standard information, and injection molding materials of several historical pipe fittings.

[0101] In some embodiments, the injection molding material can also be selected according to the relevant information of historical pipe fittings. Similar to the target pipe fitting, the main factors affecting the injection molding material of historical pipe fittings are the material information and standard information of historical pipe fittings. Therefore, obtain the material information, standard information, and injection molding materials of several historical pipe fittings.

[0103] In some embodiments, since there is a corresponding injection molding material for the material information of the historical pipe fitting and a corresponding injection molding material for the standard information of the historical pipe fitting, the corresponding relationships between the material information of the historical pipe fitting, the standard information of the historical pipe fitting, and the injection molding material of the historical pipe fitting can be obtained according to the material information of the historical pipe fitting, the standard information of the historical pipe fitting, and the injection molding material of the historical pipe fitting.

[0104] S43: Select the injection molding material for the historical pipe fitting based on the corresponding relationships between the material information of the historical pipe fitting, the standard information of the historical pipe fitting, and the injection molding material of the historical pipe fitting.

[0105] In some embodiments, since both the material information of the historical pipe fitting and the standard information of the historical pipe fitting affect the injection molding material of the historical pipe fitting, it is necessary to obtain the corresponding relationships between the material information of the historical pipe fitting, the standard information of the historical pipe fitting, and the injection molding material of the historical pipe fitting respectively. Specifically, based on the corresponding relationships between the material information of the historical pipe fitting, the standard information of the historical pipe fitting, and the injection molding material of the historical pipe fitting, obtain the injection molding material of the historical pipe fitting corresponding to both the material information of the historical pipe fitting and the standard information of the historical pipe fitting; based on the injection molding material of the historical pipe fitting corresponding to both the material information of the historical pipe fitting and the standard information of the historical pipe fitting, select the injection molding material of the historical pipe fitting. In this way, select the injection molding material that satisfies both the material information of the historical pipe fitting and the standard information of the historical pipe fitting as the injection molding material of the historical pipe fitting.

[0106] Finally, based on the obtained injection molding material of the historical pipe fitting, select the injection molding material of the historical pipe fitting as the injection molding material of the target pipe fitting. Through this method, the injection molding material of the target pipe fitting can be selected more quickly and efficiently. In summary, since the present application can find the corresponding pipe fitting prefabrication end 1, steel skeleton 3, and injection molding material based on the relevant information of the historical pipe fitting, and the historical pipe fitting is of the same type as the target pipe fitting, the information of the pipe fitting prefabrication end 1, steel skeleton 3, and injection molding material of the historical pipe fitting can be directly used as the information of the pipe fitting prefabrication end 1, steel skeleton 3, and injection molding material of the target pipe fitting. Thus, the pipe fitting prefabrication end 1, steel skeleton 3, and injection molding material of the target pipe fitting can be selected more quickly, efficiently, and accurately, and then the target pipe fitting can be manufactured more quickly, efficiently, and accurately.
