Description

Technical Field

[0001] This application relates to a three-dimensional forging apparatus. Background Technology

[0002] Forging refers to a processing method that uses forging equipment to apply pressure to a billet, causing it to deform into a forging. Forging is more environmentally friendly and safer than casting. Forging can eliminate defects generated during metal smelting and optimize the microstructure. During forging, the influence of the die and the pressure-applying components on the forging equipment must be considered. Currently, the common method is to place the billet in a die for fixation and then perform stamping forging. This method produces billet edges, and the resulting product is prone to structural defects. Therefore, improvements to existing forging methods and equipment are needed to address these issues. Utility Model Content

[0003] To address the aforementioned problems, this application proposes a three-dimensional forging apparatus, comprising a lower support portion, a lower support mold disposed above the lower support portion, an upper support mold disposed above the lower support mold and cooperating with the lower support mold, and an upper pressure application portion disposed below the upper support mold. A forging space is formed between the upper and lower support molds. One side of the forging space includes a first stamping channel, and the other side includes a second stamping channel. A first stamping force application portion cooperating with the first stamping channel is disposed on one side of the forging space, and a second stamping force application portion cooperating with the second stamping channel is disposed on the other side. This application employs an integral mold structure composed of the upper and lower support molds, and establishes the first and second stamping channels. By cooperating the first stamping force application portion with the first stamping channel and the second stamping force application portion with the second stamping channel, the reliability of the forged product can be guaranteed, preventing the formation of blank edges and avoiding defects after forging. This application uses a casting process, which is more environmentally friendly and has better safety during processing compared to casting.

[0004] Preferably, the first stamping force application part includes a first stamping plate, the first stamping plate is fixedly connected to a first stamping side piston rod, and the first stamping side piston rod is cooperated with a first stamping side piston cylinder;

[0005] The second stamping force-applying part includes a second stamping plate, which is fixedly connected to a second stamping lateral piston rod, which is cooperating with a second stamping lateral piston cylinder. The side portion of this application utilizes the cooperation of a first stamping plate and a second stamping plate, enabling casting deformation of the internal blank and ensuring structural reliability.

[0006] Preferably, a vertical through space is provided between the first stamping plate and the second stamping plate at the innermost position of the forging space.

[0007] Preferably, at least one side of the first stamping plate and / or the second stamping plate is abutted against the position of the lower support mold and / or the upper support mold.

[0008] Preferably, an overflow groove is provided on the side of the vertical through space where the contact position between the lower support mold and / or upper support mold corresponding to the first stamping plate and / or the second stamping plate is located near the vertical through space. The vertical through space of this application can form an intermediate connecting component, avoiding defects during the casting process. Furthermore, by providing an overflow groove, it is ensured that during use, if excessive material damages the mold itself, the overflowing material is easily removed.

[0009] Preferably, the vertical cross-sectional area of ​​the vertically penetrating space is gradually varied.

[0010] Preferably, the upper pressure part includes an upper pressure piston rod, which is configured to cooperate with an upper pressure piston cylinder.

[0011] Preferably, the lower support portion includes a lower support piston rod, which is configured to cooperate with a lower pressure piston cylinder.

[0012] Preferably, the forging space in the lower support die and the forging space in the upper support die are symmetrically arranged.

[0013] This application can bring the following beneficial effects:

[0014] 1. This application adopts an integral mold structure consisting of an upper support mold and a lower support mold, and sets up a first stamping channel and a second stamping channel. By cooperating the first stamping force application part with the first stamping channel and the second stamping force application part with the second stamping channel, the reliability of the forged product can be guaranteed, no blank edge is generated, and defects after forging can be avoided.

[0015] 2. The side of this application uses a first stamping plate and a second stamping plate in combination, which can perform casting deformation on the internal blank and ensure structural reliability.

[0016] 3. The vertical through space of this application can form a connecting component in the middle, avoiding defects during the casting process.

A forging space 5 is formed between the upper support mold 3 and the lower support mold. One side of the forging space 5 includes a first stamping channel 6, and the other side includes a second stamping channel 7. A first stamping force application part 8 cooperating with the first stamping channel 6 is provided on one side of the forging space 5, and a second stamping force application part 9 cooperating with the second stamping channel 7 is provided on the other side.

[0022] In use, the blank is placed on the lower support mold 2, and then the upper pressure part 4 is used to press the upper support mold 3 onto the lower support mold 2 to form a forging space 5. Then, the first stamping force part 8 is used on both sides to press the first stamping channel 6, and the second stamping force part 9 is used to press the second stamping channel 7, thus completing the forging of the blank. Then, the first stamping force part 8, the second stamping force part 9 and the upper support mold 3 are removed, thus completing the forging of the blank in the forging space 5 and obtaining the forging part.

[0023] In the second embodiment, as Figure 1-2 As shown, a three-dimensional forging device includes a lower support part 1, a lower support mold 2 above the lower support part 1, an upper support mold 3 above the lower support mold 2 and cooperating with the lower support mold 2, and an upper pressure part 4 below the upper support mold 3. A forging space 5 is formed between the upper support mold 3 and the lower support mold. One side of the forging space 5 includes a first stamping channel 6, and the other side includes a second stamping channel 7. A first stamping force application part 8 cooperating with the first stamping channel 6 is provided on one side of the forging space 5, and a second stamping force application part 9 cooperating with the second stamping channel 7 is provided on the other side.

[0026] The forging space 5 located in the lower support mold 2 is symmetrically arranged with the forging space 5 located in the upper support mold 3.

[0027] In use, the blank is placed on the lower support mold 2, and then the upper pressure part 4 presses the upper support mold 3 onto the lower support mold 2 to form the forging space 5. That is, the upper pressure piston rod 18 drives the upper support mold 3 to abut against the lower support mold 2. Then, the first lateral piston rod drives the first stamping plate 10 to press into the first stamping channel 6, and the second lateral piston rod drives the second stamping plate 13 to press into the second stamping channel 7, thus completing the forging of the blank. The excess blank will be pressed into the overflow groove 17.
