[0002] In the domestic container manufacturing industry, with the rapid development of materials science, manufacturing equipment, etc., container specifications have started to be designed and manufactured towards large sizes. In the head industry, due to the limitations of forming equipment, the overall manufacturing capacity is limited to head specifications with a diameter of less than 10 meters. For specifications with a diameter of more than 10 meters, only the method of segmented manufacturing followed by welding and forming can be adopted. During the segmented manufacturing process, the main forming is the design and manufacturing of the mold. The traditional mold design and manufacturing is to manually draw the mold assembly, and then disassemble the mold for cutting and correction during the pressing process to ensure that the gap of the head section is qualified. However, through manual line drawing and cutting, the mold needs to be corrected multiple times, and the mold manufacturing time is relatively long. Summary of the Invention

[0024] Now, the present invention will be described in detail with reference to the accompanying drawings. This figure is a simplified schematic diagram, which only illustrates the basic structure of the present invention in a schematic way, so it only shows the components related to the present invention.
[0025] Please refer to Figures 1 to 4 , the present invention provides a manufacturing method for a large-scale head segment die, and this manufacturing method includes the following steps:
[0026] Step S1: Select materials and prepare steel plates. In this implementation mode, the steel plate is made of S30408 stainless steel material, and the thickness dimension of the steel plate is 6 mm.
[0027] Among them, the S30408 stainless steel material is an austenitic stainless steel material, which has good corrosion resistance, heat resistance, low-temperature strength and other characteristics.
[0028] Step S2: Draw and layout, use drawing software to draw the upper die 1 and the lower die 2, and layout the plates required for the upper die 1 and the lower die 2. In this implementation mode, the drawing software is one or more of CAD, solidworks, and UG.
[0029] Furthermore, the upper die 1 cooperates with the lower die 2, and the head segment is located between the upper die 1 and the lower die 2.
[0030] The upper die 1 includes an upper rib plate 11, a first side plate 12, a second side plate 13, an upper strengthening block 14 and an upper panel 15. There are multiple upper rib plates 11, and multiple upper rib plates 11 are all inserted into the first side plate 12. The second side plate 13 is arranged at opposite ends of the multiple upper rib plates 11. The second side plate 13 is located below the first side plate 12 and is in contact with the first side plate 12, so as to increase the connection stability between the multiple upper rib plates 11. The upper panel 15 is arranged at the bottom of the multiple upper rib plates 11. There are multiple upper strengthening blocks 14, and multiple upper strengthening blocks 14 are arranged between the upper rib plates 11 and the upper panel 15. Specifically, one end of the upper strengthening block 14 is fixedly connected to the upper rib plate 11, and the other end of the upper strengthening block 14 is fixedly connected to the upper panel 15. By arranging the upper strengthening blocks 14, the support strength between the upper panel 15 and the upper rib plates 11 can be increased.
[0031] Furthermore, a first insertion block 111 is provided on the upper rib plate 11, and a first insertion slot 121 is formed on the first side plate 12. The first insertion block 111 is inserted into the first insertion slot 121, thereby realizing the connection between the upper rib plate 11 and the first side plate 12.
[0032] The lower mold 1 includes a lower rib plate 21, a third side plate 22, a fourth side plate 23, a lower reinforcing block 24, and a lower panel 25. There are multiple lower rib plates 21, and multiple lower rib plates 21 are all inserted into the third side plate 22. The fourth side plate 23 is arranged at opposite ends of the multiple lower rib plates 21. The fourth side plate 23 is located above the third side plate 22 and is in contact with the third side plate 22, thereby being able to increase the connection stability between the multiple lower rib plates 11. The lower panel 25 is arranged on the top of the multiple lower rib plates 21, and the lower reinforcing block 24 is arranged between the lower rib plate 21 and the lower panel 25. Specifically, one end of the lower reinforcing block 24 is fixedly connected to the lower rib plate 21, and the other end of the lower reinforcing block 24 is fixedly connected to the lower panel 25. By providing the lower reinforcing block 24, the support strength between the upper panel 15 and the upper rib plate 11 can be increased.
[0033] Furthermore, a second insertion block 211 is provided on the lower rib plate 21, and a second insertion slot 221 is formed on the third side plate 22. The second insertion block 211 is inserted into the second insertion slot 221, thereby realizing the connection between the lower rib plate 21 and the third side plate 22.
[0034] Step S3: Laser cutting. Laser cutting is performed on the steel plate according to the plates required for the upper mold 1 and the lower mold 2 that have been typeset. Specifically, the steel plate is cut into multiple upper rib plates 11, two first side plates 12, two second side plates 13, multiple upper reinforcing blocks 14, one upper panel 15, multiple lower rib plates 21, two third side plates 22, two fourth side plates 23, multiple lower reinforcing blocks 24, and one lower panel 25. In this embodiment, laser cutting has the advantages of no burrs, no wrinkles, and high precision. Therefore, it is not necessary to correct the cut plates anymore, greatly saving the production time.
[0035] Step S4: Mold assembly. The plates of the multiple upper molds 1 are assembled and spliced to form the upper mold 1, and the plates of the multiple lower molds 2 are assembled and spliced to form the lower mold 2. Specifically, multiple upper rib plates 11, two first side plates 12, two second side plates 13, multiple upper reinforcing blocks 14, and one upper panel 15 are assembled and spliced into the upper mold 1, and multiple lower rib plates 21, two third side plates 22, two fourth side plates 23, multiple lower reinforcing blocks 24, and one lower panel 25 are assembled and spliced into the lower mold 2.
[0036] Step S5: Welding. Weld the upper die 1 and the lower die 2. Specifically, first weld the weld seams between the two second side plates 13 and the multiple upper rib plates 11, and the weld seams between the multiple upper rib plates 11 and the upper panel 15. Then weld the multiple upper strengthening blocks 14 between the upper rib plates 11 and the upper panel 15. Then weld the weld seams between the two fourth side plates 23 and the multiple lower rib plates 21, and the weld seams between the multiple lower rib plates 21 and the lower panel 25. Finally, weld the multiple lower strengthening blocks 24 between the lower rib plates 21 and the lower panel 25.
[0037] In this embodiment, the welding method for the upper die 1 and the lower die 2 is plasma welding. This welding method can greatly improve the plasticity and toughness of the weld seams on the upper die 1 and the lower die 2, and prevent the weld seams on the upper die 1 and the lower die 2 from cracking. In other embodiments not shown, the welding method can also be submerged arc welding or manual welding, which is not limited here.
[0038] The manufacturing method of the large head segment die provided by the present invention draws and arranges the drawing on the drawing software, and laser cuts the steel plate according to the required plates of the upper die 1 and the lower die 2 after arrangement. Thus, it is not necessary to manually draw lines and cut on the steel plate, and it is also not necessary to correct the cut plates, which greatly saves the manufacturing time and labor costs.
[0039] Inspired by the above ideal embodiments of the present invention, through the above description, relevant staff can make various changes and modifications completely within the scope not deviating from the present invention. The technical scope of this invention is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
