Description

Technical Field

[0001] This utility model relates to a technical improvement of a forging equipment for ferrous liquid metal, specifically a fixture for a forging die for ferrous liquid metal. Background Technology

[0002] Ferrous metals typically refer to metals such as iron, manganese, and chromium that are smelted after being mixed in different proportions. They are characterized by high hardness and high wear resistance. To further improve the density of the metal and enhance its hardness and wear resistance, forging processes can be used for manufacturing. The forging process of ferrous liquid metals generally involves pressing the ferrous metal into a solid state using a large-tonnage press. The lower die contains the liquid ferrous metal, and the upper die is installed on the telescopic end of the press. The lower die is fed into the extrusion station of the large-tonnage press for forging.

[0003] Currently, the process of feeding the lower die into the press mainly uses a lifting device, that is, the lower die is equipped with a hook, and the hook is manually hooked onto the lower die before the die is transported by a gantry crane. This method increases the danger of manual operation, increases the instability of the lower die during lifting, and reduces the production efficiency of forging.

[0004] However, this hoisting method is used because the lower mold containing molten black metal is relatively heavy, and ordinary robotic arms are unable to transport the small mold containing molten black metal. Therefore, how to stably clamp the lower mold in the forging process of molten black metal for easy transportation is a technical problem that needs to be solved. Utility Model Content

[0005] Based on the aforementioned problems in the existing technology, this utility model provides a fixture for forging dies of ferrous liquid metal. Through the structural design and layout of the fixture, stable clamping, flipping and transportation of the lower die can be achieved.

[0006] The technical solution adopted by this application to solve its technical problem is: a fixture for forging dies of ferrous liquid metal, including a sprocket, a rotating shaft and a mounting base. The sprocket is located above the mounting base and is linked to the rotating shaft through a chain. The rotating shaft is located below the mounting base. One end of the rotating shaft is provided with a gripper module including two cylindrical parts. The other end of the rotating shaft is provided with a counterweight. The weight of the counterweight is not less than the weight of the gripper module. The line connecting the center of the two cylindrical parts and the center of the sprocket on the same projection plane is an equilateral triangle.

[0007] Preferably, the mounting base is provided with a strip groove, through which the chain passes and is linked with the sprocket and the shaft respectively.

[0008] Preferably, the gripper module includes a base, a cylindrical component, and a flange. The base is centrally connected to a rotating shaft, the cylindrical component passes through the base and is located on one side of the base, and the flange is located on the other side of the base and connected to the cylindrical component. The flange is screwed to the base.

[0009] Preferably, the cylindrical component and the flange are integrally formed.

[0010] Preferably, the base is provided with a slot, and the flange is also engaged with the slot.

[0011] Preferably, the mounting base is installed in the housing, and the base is provided with a first locking block on both sides, and the housing is provided with a second locking block, wherein the first locking block can abut against the second locking block.

[0012] The beneficial effects of this utility model are as follows: The clamp for forging dies of ferrous liquid metal can tilt the entire clamping jaw assembly at an angle while ensuring the stability of the jaw assembly connection, and ensure the stability of the action process. At the same time, the overall stability of the entire clamp is further improved by the equilateral triangle design, thereby effectively realizing the stable clamping, rotation and transportation of the lower die; it replaces the traditional hook hoisting method, and can greatly improve the production efficiency of forging ferrous liquid metal.

Detailed Implementation

[0014] This utility model discloses a fixture for forging dies of ferrous liquid metal, such as... Figure 3As shown, the rotating shaft 2 and the gripper module 5 are installed in a housing 12 and located at the lower end of the gripper arm 13, and are driven by the motor module 17. The fixture of this utility model includes a sprocket 1, a rotating shaft 2, and a mounting base 3. The mounting base 3 can form the top of the housing 12. The motor module 17 (a module formed by a motor and a reducer) can be installed on the mounting base 3 and is linked to the sprocket 1 via the rotating shaft. The sprocket 1 is located above the mounting base 3 and is linked to the rotating shaft 2 via a chain 4. The chain 4 can generally be two or more. The rotating shaft 2 is located at the mounting base 12. The base 3 can be installed in the housing 12 and rotates with the housing 12. A gripper module 5 is provided on one side of the rotating shaft 2, located outside the housing 12. A counterweight 6 is provided on the other side of the rotating shaft 2, located inside the housing 12, and its weight is not less than the weight of the gripper module 5, generally 1.5-2 times that of the gripper module 5. Two symmetrically distributed cylindrical parts 9 are provided on the gripper module 5. The line connecting the center of each of the two cylindrical parts 9 and the center of the sprocket 1 on the same projection plane forms an equilateral triangle. The mounting base 3 has a strip groove 7, through which the chain 4 passes and is linked with both the sprocket 1 and the rotating shaft 2. This design allows the gripper module 5 to maintain the stability of the rotating shaft 2 after clamping with the lower mold, thereby maintaining the transmission stability of the sprocket 1 and the chain 4. Generally, a sprocket 2 18 is provided on the rotating shaft 2 and on one side of the counterweight 6. The sprocket 2 18 drives the chain 4, thereby achieving stable rotation of the lower mold through the above transmission method via the motor module 17. The sprocket 2 18 and the counterweight 6 can be an integrally formed structure.

[0015] The gripper module 5 includes a base 8, a cylindrical component 9, and a flange 10. The base 8 is centrally connected to the rotating shaft 2. The cylindrical component 9 passes through the base 8 and is located on one side of the base 8. The flange 10 is located on the other side of the base 8 and is connected to the cylindrical component 9. The flange 10 is screwed to the base 8. The cylindrical component 9 and the flange 10 are integrally formed. The base 8 is provided with a slot 11, and the flange 10 is also engaged with the slot 11. During installation, the flange 10 is first nested in the slot 11, and the cylindrical component 9 passes through the base 8. The diameter of the cross-section of the cylindrical component 9 is generally not less than 20 cm, and it is an integrally formed structure of cast iron and flange 10, which has the characteristics of high hardness, high rigidity, and high temperature resistance. The lower mold is provided with a slot for the cylindrical component 9 to be inserted into the slot, thereby lifting and flipping the lower mold. The flange 10 is screwed to the base 8, and the bolts are distributed in a circle. This design can further ensure that the gripper module 5 can stably clamp the lower mold.

[0016] In practical implementation, the clamping arm 13 approaches the lower mold, and the cylindrical parts 9 on both sides of the base 8 are inserted into the slots of the lower mold. The lower mold is then raised and lowered by the up-and-down movement of the clamping arm 13. The tilting and flipping of the lower mold are controlled by the drive of the motor module. To further achieve unilateral flipping of the gripper module 5, such as... Figure 1As shown, the mounting base 3 is installed in the housing 12. The base 8 has two locking blocks 14 on both sides, and the housing 12 has two locking blocks 15. The locking blocks 14 can abut against the locking blocks 15. The locking blocks 15 can be L-shaped and horizontally positioned. If there are two locking blocks 15, they can also be L-shaped and centrally symmetrically distributed, thereby controlling the flipping and reversing of the gripper module 5. The operator can stand on the non-tilting / flipping side, ensuring operator safety. The above structure can complete the loading of the lower mold at a large-tonnage press and the demolding and unloading of the die-cast ferrous metal from the lower mold.

[0017] The above embodiments are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
