Description

Technical Field

[0001] This utility model relates to the field of forging die tooling technology, specifically a combined forging die tooling. Background Technology

[0002] Forging dies are a general term for molds used to form metal in a hot or cold state. Due to the different working characteristics of various forging equipment, the structures of their forging dies vary considerably, and there are also slight differences in the die cavity design. A sound forging die design process should first consider: obtaining forgings that meet dimensional accuracy requirements and have good microstructure properties, while also meeting productivity requirements; secondly, it should also consider that the forging die has sufficient strength and a long service life, and is simple to manufacture, easy to install, adjust, and maintain. Therefore, a comprehensive analysis should be conducted when designing forging dies.

[0003] Existing forging dies need to be fixed on a specific structure during use to ensure that they do not wobble or shift under stress during forging, thus improving the quality of the forged workpiece. However, the fixing and disassembly of existing forging dies are inconvenient, making it difficult to guarantee the speed of die assembly and replacement, and thus failing to meet the needs of modern production.

[0004] Therefore, a modular forging die fixture that can be easily assembled and disassembled is needed. Summary of the Invention

[0005] To address the aforementioned issues, this invention proposes a combined forging die fixture, consisting of a lower die and an upper die used together. The lower die is fixed to the base plate and can be quickly disassembled and assembled, facilitating cleaning or replacement of the die.

[0006] To achieve the above objectives, the present invention proposes the following specific solutions:

[0007] A combined forging die fixture includes a base plate, a lower die on the top of the base plate, a limiting groove in the middle of the bottom surface of the lower die, symmetrical triangular slots on the upper inner wall of the limiting groove, a connecting groove in the middle of the top surface of the base plate, the connecting groove communicating with the limiting groove, symmetrical rectangular slots on the inner wall of the connecting groove, a moving groove on the top surface of the inner side of the rectangular slot, a limiting plate symmetrically arranged on the inner side of the connecting groove, the upper end of the limiting plate located inside the limiting groove, a triangular block fixed to the upper side wall of the limiting plate, the triangular block located inside the triangular slot, a rectangular plate fixed to the lower side wall of the limiting plate, the rectangular plate movably inserted into the inner side of the rectangular slot, a spring fixed to one end of the rectangular plate, one end of the spring fixed to the inner wall of the rectangular slot, a moving plate fixed to the edge of the top surface of the rectangular plate, the moving plate passing through the moving groove, a fixing post symmetrically fixed to the top surface of the lower die, an upper die above the lower die, a through hole symmetrically provided on the top surface of the upper die, the fixing post passing through the through hole.

[0008] As a preferred technical solution of the combined forging die tooling of this utility model, the bottom plate is symmetrically provided with a protective box on the top surface. The protective box is located outside the moving plate. A rotating block is symmetrically fixed on the outer wall of one side of the lower end of the protective box, and a rotating shaft is fixed on the side wall of the rotating block.

[0009] As a preferred technical solution of the combined forging die tooling of this utility model, a fixing block is symmetrically fixed on the top surface of the base plate, and a rotating hole is provided on the upper side wall of the fixing block, and the rotating shaft passes through the rotating hole.

[0010] As a preferred technical solution of the combined forging die tooling of this utility model, a vertical plate is fixed to the edge of the top surface of the base plate, and a top plate is fixed to the top of the vertical plate.

[0011] As a preferred technical solution of the combined forging die tooling of this utility model, a hydraulic device is fixed to the bottom edge of the top plate, and a pressure plate is fixed to the lower end of the hydraulic device, with the pressure plate located above the upper die.

[0012] As a preferred technical solution of the combined forging die tooling of this utility model, the bottom surface of the lower die is symmetrically provided with an insertion groove, the insertion groove is located on both sides of the limiting groove, and the top surface of the base plate is symmetrically fixed with an insertion post, the insertion post being movably inserted into the inner side of the insertion groove.

[0013] As a preferred technical solution of the combined forging die tooling of this utility model, a first handle is symmetrically fixed on the upper outer wall of the lower die, and a second handle is symmetrically fixed on the upper outer wall of the upper die.

[0014] As a preferred technical solution of the combined forging die tooling of this utility model, the bottom surface of the base plate is symmetrically fixed with a support plate.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The lower mold of this invention is fixed to the top surface of the base plate. When the lower mold is placed from above onto the top surface of the base plate, the limiting groove on the bottom surface of the lower mold encloses the triangular blocks on the side walls of the two limiting plates. As the lower mold moves downward, the inner wall of the limiting groove presses against the two triangular blocks, causing them to move closer together. This, in turn, moves the two rectangular plates closer together, stretching the two springs. After the lower mold is fully placed on the top surface of the base plate and the insertion post is inserted into the insertion groove, the two springs can pull the two triangular blocks apart through their rebound force, thus locking them into the triangular plates. The lower die is vertically limited by the slot, and horizontally limited by the insert pin, ensuring that the lower die will not move. During disassembly, by pushing the two moving plates closer together, the two rectangular plates move closer together, thereby moving the two limiting plates closer together and moving the triangular block out of the triangular slot, allowing the lower die to be moved upward for disassembly. This solution facilitates the disassembly and assembly of the lower die, making it easy to change the die according to different forging needs and to clean the die, thus improving the efficiency of forging processing.

[0017] This utility model has a fixing block fixed on the top surface of the base plate. The side wall of the fixing block is provided with a rotating hole. The rotating shaft of the side wall of the rotating block, which is fixed to the outer wall of the protective box, is sleeved inside the rotating hole. Therefore, the protective box can be rotated around the rotating shaft. The protective box houses the movable plate that controls the movement of the limiting plate inside, which can prevent accidental contact with the movable plate from causing the lower mold to loosen. When it is necessary to disassemble the lower mold, the protective box is flipped over to expose the movable plate. After the movable plate is pushed, the protective box is flipped back, and the protective box can hold the movable plate and prevent the spring from pulling the limiting plate to move, thus facilitating the disassembly of the lower mold. The operation is simple and fast, with multiple functions and good practicality. Attached Figure Description

[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. Example

[0027] Please see Figure 1-6 As shown, the present invention provides the following technical solution: a combined forging die fixture, including a base plate 1, with a support plate 11 symmetrically fixed to the bottom surface of the base plate 1. The support plate 11 can support the base plate 1 from below to prevent the base plate 1 from tilting or shaking.

[0028] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, specifically, a lower mold 2 is provided above the base plate 1 for forging materials in conjunction with the upper mold 3. A limiting groove 23 is provided in the center of the bottom surface of the lower mold 2 to accommodate the limiting plate 15 and provide a connecting channel for the triangular locking block 151. The upper inner wall of the limiting groove 23 is symmetrically provided with triangular locking grooves 231 for limiting the lower mold 2 in conjunction with the triangular locking block 151. A connecting groove 14 is provided in the center of the top surface of the base plate 1 for connecting the limiting plate 15. The connecting groove 14 communicates with the limiting groove 23. A rectangular groove 141 is symmetrically provided on the inner wall of the connecting groove 14 for moving the rectangular plate 152. A moving groove 142 is provided on the inner top surface of the rectangular groove 141 for moving the moving plate 154. 4. A limiting plate 15 is symmetrically provided on the inner side to fix the triangular block 151 and drive the triangular block 151 to move. The upper end of the limiting plate 15 is located inside the limiting groove 23. The triangular block 151 is fixed to the upper side wall of the limiting plate 15 to limit the vertical movement of the lower mold 2. The triangular block 151 is located inside the triangular groove 231. A rectangular plate 152 is fixed to the lower side wall of the limiting plate 15 and can drive the limiting plate 15 to move. The rectangular plate 152 is movably inserted into the inner side of the rectangular groove 141. A spring 153 is fixed to one end of the rectangular plate 152. The spring pulls the rectangular plate 152 to move. One end of the spring 153 is fixed to the inner wall of the rectangular groove 141. The top of the rectangular plate 152 A movable plate 154 is fixed to the edge of the mold 2 to push the rectangular plate 152 to move. The movable plate 154 passes through the movable groove 142. The bottom surface of the lower mold 2 is symmetrically provided with an insertion groove 24 to accommodate the insertion post 18, which is adapted to the size of the insertion post 18. The insertion groove 24 is located on both sides of the limiting groove 23. The top surface of the bottom plate 1 is symmetrically fixed with an insertion post 18 to restrict the lateral movement of the lower mold 2. The insertion post 18 is movably inserted into the inside of the insertion groove 24. The upper outer wall of the lower mold 2 is symmetrically fixed with a first handle 21 to lift the lower mold 2. In this design, when the lower mold 2 moves down close to the bottom plate 1, the two triangular blocks 151 will enter the inside of the limiting groove 23 and be squeezed by the inner wall of the limiting groove 23. Triangular locking blocks 151 move closer to each other, causing the two springs 153 to be stretched. When the lower mold 2 contacts the base plate 1 and the insertion post 18 is inserted into the insertion slot 24, the two triangular locking blocks 151 move and engage with the inner sides of the two triangular locking slots 231 under the pull of the rebound force of the two springs 153, thus limiting the lower mold 2 and completing the installation of the lower mold 2. When disassembling, by pushing the two moving plates 154, the two limiting plates 15 can be moved closer to each other, thereby causing the two triangular locking blocks 151 to disengage from the inner sides of the two triangular locking slots 231, so that the lower mold 2 can be moved upward and disassembled. The disassembly and assembly are convenient, making it easy to replace or clean the mold and improve processing efficiency. Example

[0029] In another embodiment of this solution, refer to Figure 1 , Figure 2 and Figure 5As shown, specifically, a protective box 17 is symmetrically provided on the top surface of the base plate 1 to prevent people from accidentally touching the movable plate 154. The protective box 17 is located outside the movable plate 154. A rotating block 171 is symmetrically fixed on the outer wall of one side of the lower end of the protective box 17 to fix the rotating shaft 172. The rotating shaft 172 is fixed on the side wall of the rotating block 171, so that the protective box 17 can be flipped. A fixing block 16 is symmetrically fixed on the top surface of the base plate 1 to support the rotating shaft 172. A rotating hole 161 is provided on the upper side wall of the fixing block 16 for connecting the rotating shaft 172. The rotating shaft 172 passes through the rotating hole 161. This design uses a protective box 17 to cover the moving plate 154, preventing the moving plate 154 from being accidentally touched, which would cause the triangular locking block 151 to disengage from the inside of the triangular locking slot 231, thus avoiding accidental risks and enhancing safety. Furthermore, after the moving plate 154 is pushed to move and the triangular locking block 151 disengages from the inside of the triangular locking slot 231, the protective box 17 can also hold the moving plate 154 against it, preventing the spring 153 from pulling the moving plate 154 to move. This makes it easier to move the lower mold 2 up and disassemble, making it more practical. Example

[0030] In another embodiment of this solution, refer to Figure 1 , Figure 2 and Figure 6 As shown, specifically, the top surface of the lower mold 2 is symmetrically fixed with a fixing column 22 to improve the stability of the upper mold 3. The upper mold 3 is located above the lower mold 2 to cooperate with the lower mold 2 in forging and shaping the material. The top surface of the upper mold 3 is symmetrically provided with a through hole 32 for inserting and connecting the fixing column 22. The fixing column 22 passes through the through hole 32. The upper outer wall of the upper mold 3 is symmetrically fixed with a second handle 31, which can be used to lift the upper mold 3. The top edge of the bottom plate 1 is fixed with a vertical plate 12 to support and fix the top plate 121. The top plate 121 is fixed at the top of the vertical plate 12 for fixing the hydraulic equipment 13. A hydraulic device 13 is fixed to the bottom edge (the hydraulic device 13 is existing technology, and the specific operation mode and principle can be referred to the electric hydraulic cylinder in the existing technology, which is controlled by an external power source to open and close, so it is not described in detail here). A pressure plate 131 is fixed to the lower end of the hydraulic device 13. The pressure plate 131 is located above the upper mold 3 and can apply pressure to the upper mold 3. In this solution, the upper mold 3 and the lower mold 2 are combined by inserting the fixing column 22 into the through hole 32. The pressure plate 131 is driven to move down by the hydraulic device 13 to apply pressure to the upper mold 3, so that the material is forged and formed inside the upper mold 3 and the lower mold 2.

[0031] The working principle and usage process of this utility model:

[0032] In use, the lower mold 2 is lifted using the first handle 21, and then the limiting groove 23 is aligned with the connecting groove 14. The lower mold 2 is then moved downwards towards the base plate 1. During the downward movement of the lower mold 2, the limiting groove 23 gradually contacts the two triangular blocks 151. The two triangular blocks 151 move into the inner side of the limiting groove 23, and the inner wall of the limiting groove 23 presses against the two triangular blocks 151, causing the two triangular blocks 151 to move closer to each other (when the two triangular blocks 151 move towards each other, they will drive the two limiting plates). 15 moves towards each other, then drives the two rectangular plates 152 to move towards each other, causing the two springs 153 to be stretched. After the lower mold 2 contacts the base plate 1 and the plug-in post 18 is inserted into the inside of the plug-in slot 24, the triangular block 151 and the triangular slot 231 are at the same height. Under the pull of the spring 153, the triangular block 151 is inserted into the inside of the triangular slot 231 to limit the lower mold 2. Then the protective box 17 is flipped over to cover the moving plate 154, thus completing the installation and fixing of the lower mold 2.

[0033] The material is placed inside the forging groove on the top surface of the lower mold 2, and then the upper mold 3 is placed above the lower mold 2. The two fixing posts 22 on the top surface of the lower mold 2 are respectively inserted into the two through holes 32 on the top surface of the upper mold 3. Then the hydraulic device 13 is started, and the hydraulic device 13 drives the pressure plate 131 to move down, applying pressure to the upper mold 3, so that the upper mold 3 presses the material and forges the material.

[0034] When it is necessary to disassemble, replace or clean the mold, grasp the second handle 31 to separate the upper mold 3 from the lower mold 2, then flip the two protective boxes 17 open, push the two moving plates 154 to move towards the lower mold 2, the moving plates 154 drive the rectangular plate 152 to move, stretch the spring 153, so that the limiting plate 15 drives the triangular block 151 to move out of the triangular slot 231, then flip the protective box 17 back to its original position, the protective box 17 can resist the moving plate 154, prevent the spring 153's rebound force from pulling the moving plate 154 to move, thus ensuring that the triangular block 151 will not be stuck in the triangular slot 231 again, finally grasp the first handle 21 to lift the lower mold 2, and the disassembly of the lower mold 2 can be completed.

[0035] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
