Description

Technical Field

[0001] This utility model relates to the technical field of industrial manufacturing, and in particular to a metal forging equipment with a protective mechanism. Background Technology

[0002] Metal forging equipment, as a basic piece of equipment in the industrial manufacturing field, is mainly used to plastically deform metal billets through high temperature and high pressure to obtain forgings of specific shapes.

[0003] During the forging process, the impact of the forging hammer or hydraulic forging press on the workpiece generates a large amount of high-temperature debris and sparks, posing a safety hazard of flying debris and injury. Current mainstream protective measures, such as fixed protective covers, can block flying debris, but they severely hinder operators from observing the workpiece's forming process and quickly loading and unloading materials, leading to a decrease in processing efficiency.

[0004] To address the above issues, we have introduced a metal forging equipment with a protective mechanism. Utility Model Content

[0005] This utility model discloses a metal forging equipment with a protective mechanism, which aims to solve the technical problems in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A metal forging equipment with a protective mechanism includes a base plate and a top plate, characterized in that: a protective housing is fixedly connected between the base plate and the top plate, and two arc surfaces are symmetrically arranged on the protective housing;

[0008] The bottom plate has a sliding groove with an arc shape, and the top plate has a through groove and a straight groove with an arc shape.

[0009] A forging hydraulic press is fixedly connected to the top plate, and a tooling table is fixedly connected to the top of the bottom plate and below the forging hydraulic press.

[0010] Two sliding protective plates are symmetrically slidably connected on the slide groove; the sliding protective plates move between the slide groove and the through groove via a drive assembly;

[0011] The drive assembly includes a sliding block slidably connected in the straight groove, a push rod fixed to the top of the sliding block, and a drive rod rotatably connected between the push rod and the upper movable end of the forging hydraulic press.

[0012] In a preferred embodiment, the drive assembly further includes two connecting rods that are rotatably connected to the outside of the top rod in an up-down symmetrical structure;

[0013] Each connecting rod is fixedly connected to a limiting plate at one end, and a sliding sleeve is fitted on the outside of each limiting plate. A connecting rod is fixedly connected to one end of each sliding sleeve.

[0014] In a preferred embodiment, each connecting rod is provided with a clearance arc structure, the position of which corresponds to the movement trajectory of the upper movable end of the forging hydraulic press.

[0015] In a preferred embodiment, each of the sliding protective plates has a vertical groove inside, and a lifting block is slidably connected in each vertical groove. A spring is fixedly connected between the bottom of the lifting block and the corresponding vertical groove.

[0016] In a preferred embodiment, each of the lifting blocks is fixedly connected to a mating rod at its top, and the top of the mating rod extends through the sliding protective plate and the through groove to the top plate.

[0017] In a preferred embodiment, the end of the limiting plate away from the connecting rod is provided with a collar structure, the size and position of which are configured to fit over the top of the mating rod.

[0018] In a preferred embodiment, each of the sliding protective plates has a slot communicating with the vertical groove, and a pull rod is fixedly connected to the outside of the mating rod, the pull rod extending to the outside of the sliding protective plate through the slot.

[0019] In a preferred embodiment, the curvature of the two arc surfaces is concentrically arranged with the arc-shaped structure of the slide and the through groove, and the moving trajectory of the sliding protective plate is consistent with the curvature of the arc surfaces.

[0020] The metal forging equipment with a protective mechanism provided by this utility model has the following advantages:

[0021] This invention inserts a mating rod into a collar structure at one end of a connecting rod. This allows the sliding protective plate to move synchronously with the forging hydraulic press, bringing the two sliding protective plates closer together to close and form a protective enclosure. This prevents sparks from flying during forging and thus avoids safety hazards to workers. When the sliding protective plate is not needed, simply pull the mating rod with a pull rod to lower it and separate it from the collar structure at one end of the connecting rod. Then, push the sliding protective plate to its maximum distance. In this way, the operation of the forging hydraulic press will not cause the sliding protective plate to move. Users can flexibly select the mode of use according to different forging parts. Attached Figure Description

[0030] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and marked in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0031] This utility model discloses a metal forging equipment with a protective mechanism.

[0032] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, a metal forging equipment with a protective mechanism includes a bottom plate 1 and a top plate 2, characterized in that: a protective housing 3 is fixedly connected between the bottom plate 1 and the top plate 2, and two arc surfaces 4 are symmetrically arranged on the protective housing 3;

[0033] The bottom plate 1 has a circular arc-shaped groove 5, and the top plate 2 has a circular arc-shaped through groove 6 and a straight groove 10.

[0034] A forging hydraulic press 7 is fixedly connected to the top plate 2, and a tooling table 8 is fixedly connected to the top of the bottom plate 1 and below the forging hydraulic press 7.

[0035] Two sliding protective plates 9 are symmetrically slidably connected on the slide 5; the sliding protective plates 9 move between the slide 5 and the through groove 6 via a drive assembly;

[0036] The drive assembly includes a sliding block 11 slidably connected in the straight groove 10, a push rod 12 fixed to the top of the sliding block 11, and a drive rod 13 rotatably connected between the push rod 12 and the upper movable end of the forging hydraulic press 7.

[0037] In this embodiment: when the upper movable end of the forging hydraulic press 7 moves downward, the drive rod 13 pushes the top rod 12, causing the sliding block 11 to slide horizontally in the straight groove 10, so that the two sliding protective plates 9 close towards the center along the arc trajectory of the sliding groove 5 and the through groove 6, thereby sealing the tooling table 8; when the forging hydraulic press 7 returns to the starting position, the drive rod 13 is pulled in the opposite direction, so that the sliding protective plates 9 move to both sides along the arc trajectory and unfold, exposing the tooling table 8.

[0038] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, in a preferred embodiment, the drive assembly further includes two connecting rods 14 that are rotatably connected to the outside of the top rod 12 in an up-down symmetrical structure;

[0039] Each connecting rod 14 is fixedly connected to a limiting plate 17 at one end, and a sliding sleeve 15 is sleeved on the outside of the limiting plate 17. A connecting rod 16 is fixedly connected to one end of the sliding sleeve 15.

[0040] In this embodiment, when the top rod 12 moves horizontally, it drives the two symmetrically arranged connecting rods 14 to rotate, causing the limiting plate 17 to slide within the sliding sleeve 15. The force is transmitted to the sliding protective plate 9 through the connecting rod 16, achieving bidirectional synchronous drive. The sliding of the connecting rod 14 within the sliding sleeve 15 can also achieve the effect of avoiding motion interference.

[0041] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, in a preferred embodiment, each of the connecting rods 16 is provided with a clearance arc structure 18, the position of which corresponds to the movement trajectory of the upper movable end of the forging hydraulic press 7.

[0042] In this embodiment, the avoidance arc structure 18 of the connecting rod 16 avoids the upper moving end of the forging hydraulic press 7 during the movement, preventing interference between the mechanisms.

[0043] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, in a preferred embodiment, each sliding protective plate 9 has a vertical groove 19 inside, and each vertical groove 19 has a lifting block 20 slidably connected to it. A spring 21 is fixedly connected between the bottom of the corresponding lifting block 20 and the corresponding vertical groove 19. Each lifting block 20 has a mating rod 22 fixedly connected to its top. The top of the mating rod 22 passes through the sliding protective plate 9 and the through groove 6 and extends to the top plate 2. Each end of the limiting plate 17 away from the connecting rod 14 is provided with a collar structure. The size and position of the collar structure are configured to fit the top of the mating rod 22. Each sliding protective plate 9 has a slot 23 communicating with the vertical groove 19. A pull rod 24 is fixedly connected to the outside of the mating rod 22. The pull rod 24 extends to the outside of the sliding protective plate 9 through the slot 23. The curvature of the two arc surfaces 4 is concentric with the arc structure of the sliding groove 5 and the through groove 6, and the movement trajectory of the sliding protective plate 9 is consistent with the curvature of the arc surface 4.

[0044] In this embodiment, the lifting block 20 inside the sliding protective plate 9 can slide up and down within the vertical groove 19. When the sliding protective plate 9 needs to be moved, the mating rod 22 is inserted into the collar structure at one end of the connecting rod 14. In this way, the sliding protective plate 9 can move synchronously with the operation of the forging hydraulic press 7, so that the two sliding protective plates 9 move closer to each other and close, forming an enclosed protection to prevent sparks from flying during forging and thus avoiding safety hazards to workers. When the sliding protective plate 9 is not needed, the mating rod 22 is pulled by the pull rod 24, causing the mating rod 22 to descend and separate from the collar structure at one end of the connecting rod 14. Then, the sliding protective plate 9 is pushed to its farthest distance, so that the operation of the forging hydraulic press 7 will not cause the sliding protective plate 9 to move.

[0045] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
