Abstract
Description
Technical Field
[0001] This utility model relates to the field of niobium-zirconium ingot processing technology, and in particular to a multi-cavity niobium-zirconium ingot forging die. Background Technology
[0002] Currently, niobium-zirconium ingots are cast to a relatively short length, making them unsuitable for radial forging. They must be forged to a certain length using rapid forging before being transferred to the radial forging process. During rapid forging, the ingots must first be forged to a certain size using a large anvil before being replaced with a small anvil for further forging. This process involves repeated disassembly and reassembly of the large and small anvils, which is time-consuming and labor-intensive, prolonging the forging time and resulting in low forging efficiency. Summary of the Invention
[0003] In order to solve the technical problems existing in the above-mentioned technology, it is necessary to provide a multi-cavity niobium-zirconium ingot forging die.
[0004] A multi-cavity niobium-zirconium ingot forging die includes an upper anvil and a lower anvil. The upper anvil is located directly above the lower anvil and can move longitudinally along the upper part of the lower anvil. At least two upper dies are detachably mounted on the lower end face of the upper anvil, and each upper die has an upper forging groove on its lower end face. The size of each upper forging groove is different. At least two lower dies are detachably mounted on the upper end face of the lower anvil. Each lower die corresponds to each upper die, and each lower die has a lower forging groove on its upper end face. The size of each lower forging groove is different.
[0005] Preferably, the lower end face of the upper anvil and the upper end face of the lower anvil are provided with grooves for mounting the upper mold and the lower mold.
[0006] Preferably, the groove has a first V-shaped groove symmetrically formed on both sides, and the upper mold and the lower mold have a second V-shaped groove corresponding to the first V-shaped groove on both sides. The first V-shaped groove and the second V-shaped groove are fixed by a diamond-shaped wedge key.
[0007] Preferably, a threaded hole is provided on the bottom surface of the groove, and stepped through holes corresponding to the threaded hole are provided on both the upper mold and the lower mold. The stepped through holes and the threaded holes are fixed to the upper mold and the upper anvil, and the lower mold and the lower anvil, by bolts.
[0008] Preferably, the lower end face of the upper mold is flush with the lower end face of the upper anvil, and the upper end face of the lower mold is flush with the upper end face of the lower anvil.
[0009] Preferably, the upper forging groove and the lower forging groove are arc-shaped.
[0010] Preferably, a guide post is fixedly provided on the upper end surface of the lower anvil, and a guide hole adapted to the guide post is provided on the lower end surface of the upper anvil, the guide hole being able to move up and down along the guide post.
[0011] Preferably, a receiving hole is formed longitudinally along the upper end face of the guide post, and a positioning hole is formed longitudinally along the bottom surface of the guide hole.
[0012] Preferably, a spring is installed in the receiving hole, with the lower end of the spring connected to the bottom of the receiving hole and the upper end of the spring extending out of the receiving hole and connected to the bottom of the positioning hole.
[0013] Compared with the prior art, the multi-cavity niobium-zirconium ingot forging die provided by this utility model includes an upper anvil and a lower anvil. The upper anvil is located directly above the lower anvil and can move longitudinally along the upper part of the lower anvil. At least two upper dies are detachably mounted on the lower end face of the upper anvil. Each upper die has an upper forging groove on its lower end face. The size of each upper forging groove is different. At least two lower dies are detachably mounted on the upper end face of the lower anvil. Each lower die corresponds to each upper die. The size of each lower forging groove is different. By installing multiple upper and lower dies on the upper and lower anvils, and each upper and lower die having upper and lower forging grooves of different sizes, multiple cavities of different specifications and shapes are integrated into one during forging, which can meet diverse forging needs. Whether it is a small niobium-zirconium ingot or a large niobium-zirconium ingot, only the die cavity needs to be switched to complete the forging of products of different sizes. There is no need to frequently change dies, which greatly shortens the die change time and significantly improves production efficiency. Attached Figure Description

Detailed Implementation
[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0027] In the description of this utility model, it should be understood that the terms "upper", "middle", "outer", "inner", "lower", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
[0028] Please refer to Figures 1 to 4This invention provides a multi-cavity niobium-zirconium ingot forging die, including an upper anvil 01 and a lower anvil 02. The upper anvil 01 is located directly above the lower anvil 02 and can move vertically up and down along the vertical direction directly above the lower anvil 02. At least two upper dies 03 are detachably mounted on the lower end face of the upper anvil 01, each upper die 03 having an upper forging groove 31 of different sizes on its lower end face. At least two lower dies 04 are detachably mounted on the upper end face of the lower anvil 02, each lower die 04 corresponding to each upper die 03, each lower die 04 having a lower forging groove 41 of different sizes on its upper end face. In use, the lower anvil 02 can be installed on forging equipment to prevent it from moving back and forth during forging. The upper anvil 01 can be driven to move up and down by external equipment, such as a hydraulic cylinder. By installing multiple upper molds 03 and lower molds 04 on the upper anvil 01 and lower anvil 02 respectively, and each upper mold 03 and lower mold 04 has an upper forging groove 31 and a lower forging groove 41 of different sizes, multiple mold cavities of different specifications and shapes are integrated into one during forging, which can meet diverse forging needs. Whether it is a small-sized niobium-zirconium ingot or a large-sized niobium-zirconium ingot, only the mold cavity needs to be switched to complete the forging of products of different sizes. There is no need to frequently change molds, which greatly shortens the mold change time and significantly improves production efficiency.
[0029] In one embodiment, the lower end face of the upper anvil 01 and the upper end face of the lower anvil 02 are both provided with grooves 05 for mounting the upper mold 03 and the lower mold 04.
[0030] Please refer to Figure 7 , Figure 8 Specifically, first V-shaped grooves 51 are symmetrically formed on both sides of the groove 05. Second V-shaped grooves 06, corresponding to the first V-shaped grooves 51, are formed on both sides of the upper mold 03 and the lower mold 04. The first V-shaped grooves 51 and the second V-shaped grooves 06 are fixed together by diamond-shaped wedge keys. When either the upper mold 03 or the lower mold 04 becomes worn, simply remove the corresponding diamond-shaped wedge key, take out the worn upper mold 03 or lower mold 04, and then install the intact upper mold 03 or lower mold 04.
[0031] Please refer to Figure 5 , Figure 6 , Figure 9 , Figure 10In another installation method, a threaded hole 07 can be provided on the bottom surface of the groove 05. The upper mold 03 and the lower mold 04 both have corresponding stepped through holes 08. The stepped through holes 08 and the threaded holes 07 are fixed to the upper mold 03 and the upper anvil 01, and the lower mold 04 and the lower anvil 02, by bolts. When either the upper mold 03 or the lower mold 04 becomes worn, simply loosen the corresponding bolts, remove the worn upper mold 03 or lower mold 04, and then install the intact upper mold 03 or lower mold 04.
[0032] Of course, there are other detachable connection methods for the installation of the upper mold 03 and the lower mold 04, such as dovetail groove connection or T-groove connection.
[0033] In one embodiment, the lower end face of the upper mold 03 is flush with the lower end face of the upper anvil 01, and the upper end face of the lower mold 04 is flush with the upper end face of the lower anvil 02.
[0034] In one embodiment, the upper forging groove 31 and the lower forging groove 41 are arc-shaped.
[0035] Please refer to Figures 7 to 10 In one embodiment, a guide post 09 is fixedly provided on the upper end face of the lower anvil 02, and a guide hole 10 adapted to the guide post 09 is provided on the lower end face of the upper anvil 01. The guide hole 10 can move up and down along the guide post 09. The guide post 09 is located at both ends of the upper end face of the lower anvil 02, and correspondingly, the guide hole 10 is located at both ends of the lower end face of the upper anvil 01. Relying on the action of the guide post 09 and the guide hole 10, it can be ensured that the upper anvil 01 can move up and down directly above the lower anvil 02, and the niobium-zirconium ingot is forged using the upper die 03 and the lower die 04.
[0036] Please refer to Figure 4 , Figure 6 In one embodiment, a receiving hole 91 is longitudinally formed along the upper end face of the guide post 09, and a positioning hole 101 is longitudinally formed along the bottom face of the guide hole 10. Correspondingly, a spring 20 is installed in the receiving hole 91, with the lower end of the spring 20 connected to the bottom of the receiving hole 91 and the upper end of the spring 20 extending out of the receiving hole 91 and connected to the bottom of the positioning hole 101. When the upper anvil 01 moves downward, the spring 20 can effectively buffer the impact force, making the forging force act more evenly and stably on the billet. This not only reduces deformation defects in the forging, improves the dimensional accuracy and surface quality of the forging, but also extends the service life of the die and reduces production costs.
[0037] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
