Description

Technical Field

[0001] This application relates to the field of hand-held clamps, and more particularly to a hand-held clamp for forging processing. Background Technology

[0002] Forgings refer to workpieces or blanks obtained by forging and deforming metal billets. Forgings can be classified into cold forging, warm forging, and hot forging according to the temperature at which the billet is processed. Cold forging is generally processed at room temperature, while hot forging is processed at a temperature higher than the recrystallization temperature of the metal billet. Therefore, when the metal is heated to 1200 degrees Celsius during forging, the plasticity of the metal is greatly enhanced, making its movement during processing (mainly including removal from the heating furnace and turning it on the anvil during hot working) very inconvenient. Utility Model Content

[0003] To address the problem that the increased plasticity of metals when heated to 1200 degrees Celsius during metal forging makes their movement during processing (mainly including removal from the furnace and turning them on the anvil during hot working) very inconvenient, this application provides a hand-held clamp for forging processing.

[0004] The forging machining hand clamp provided in this application adopts the following technical solution:

[0005] A hand-held clamp for forging processing includes a fixed rod with telescopic components and a bracket at both ends. A cylinder is installed inside the fixed rod, and the output end of the cylinder passes through the bracket and extends outward to connect to a toothed plate. A through-hole is provided at both corners of the bracket, and a first connecting rod is connected inside the through-hole via a shaft. A sector gear is provided on one side of each of the two first connecting rods, and the two sector gears are symmetrically distributed and mesh with the toothed plate in the middle.

[0006] Preferably, both ends of the bracket are provided with through slots, and a second connecting rod is connected inside the through slots via a shaft. The second connecting rod and the first connecting rod are connected to a third connecting rod via a shaft. Each of the two third connecting rods has a clamping plate at one end opposite to the other, and the two clamping plates are symmetrically distributed from left to right.

[0007] Preferably, the telescopic assembly includes a main rod, the main rod has a threaded rod inside, a movable rod is sleeved on the outer wall of the threaded rod, one end of the movable rod passes through the main rod and extends outward to connect with the fixed rod.

[0008] Preferably, the outer wall of the main rod is provided with two symmetrical sliding openings, and each of the two sliding openings is provided with a slider, which is connected to the moving rod.

[0009] Preferably, one end of the threaded rod passes through the main rod and extends outward to be connected to a rotating plate. The outer wall of the threaded rod located between the rotating plate and the main rod is connected to a circular plate via a bearing, and the outer wall of the circular plate is provided with a handle.

[0010] Preferably, the bracket is connected to two rectangular plates, which are located above and below the first and second connecting rods.

[0011] In summary, this application includes the following beneficial technical effects:

[0012] 1. The output end of the cylinder drives the gear plate to move horizontally. Since the gear plate is meshed with the sector gears on both sides, the movement of the gear plate drives the two sector gears to move around the shaft in the passage. The movement of the two sector gears drives the two first connecting rods to move. The movement of the first connecting rods drives the second connecting rod through the third connecting rod, thereby realizing the relative or opposite movement of the two clamping plates. By adjusting the distance between the two clamping plates, forgings of different sizes can be clamped and held, making it easier for forging workers to flip and forge the forgings, thus improving the quality of the castings.

[0013] 2. By rotating the rotating plate, the rotation of the rotating plate drives the threaded rod to rotate. The rotation of the threaded rod drives the moving rod and the two sliders to move inside the sliding mouth. The movement of the moving rod drives the fixed rod to move. For some high-temperature forgings, by adjusting the length between the moving rod and the main rod, a certain distance is maintained between the worker and the forging to prevent burns.

[0018] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0019] This application discloses a handheld clamp for forging processing, as shown in the embodiments below. Figures 1-2 The system includes a fixed rod 3, with telescopic components and a bracket 5 at each end. The bracket 5 is fixedly connected to the fixed rod 3. Two rectangular plates 7 are fixedly connected to the bracket 5, located above and below the first connecting rod 8 and the second connecting rod 9, respectively. A cylinder 6 is installed inside the fixed rod 3. The output end of the cylinder 6 passes through the bracket 5 and extends outward to be fixedly connected to a toothed plate 4. Two through-holes 12 are provided at the two corners of the bracket 5. The first connecting rod 8 is connected to the inside of the through-hole 12 via a shaft. The first connecting rod 8 is movably connected to the shaft inside the through-hole 12, and the through-hole 12 is fixedly connected to the shaft inside it. A sector gear 14 is fixedly provided on one side of each of the two first connecting rods 8. The two sector gears 14 are symmetrically distributed and mesh with the toothed plate 4 in the middle. Through slots 13 are provided at both ends of the bracket 5. The second connecting rod 9 is connected to the inside of the through-hole 13 via a shaft. The second connecting rod 9 is connected to the shaft inside the through-hole 13. The rods are movably connected, and the through slot 13 is fixedly connected to the shaft inside. The second connecting rod 9 and the first connecting rod 8 are movably connected to the third connecting rod 10 through the shaft. The two third connecting rods 10 are fixedly provided with clamping plates 11 at opposite ends. The two clamping plates 11 are symmetrically distributed from left to right. The output end of the cylinder 6 drives the toothed plate 4 to move horizontally. Since the toothed plate 4 is meshed with the sector gears 14 on both sides, the movement of the toothed plate 4 drives the two sector gears 14 to move around the shaft inside the through slot 12. The movement of the two sector gears 14 drives the two first connecting rods 8 to move. The movement of the first connecting rods 8 drives the second connecting rod 9 to move through the third connecting rod 10, thereby realizing the relative or opposite movement of the two clamping plates 11. By adjusting the distance between the two clamping plates 11, forgings of different sizes can be clamped and held, making it easier for forging workers to flip and forge the forgings, thus improving the quality of the castings.

[0020] Reference Figure 1 and Figure 3The telescopic assembly includes a main rod 1, with a threaded rod 18 inside the main rod 1, rotatably connected to the main rod 1. A movable rod 2 is threadedly fitted onto the outer wall of the threaded rod 18, slidably connected to the main rod 1. One end of the movable rod 2 passes through the main rod 1 and extends outward to be fixedly connected to a fixed rod 3. Two sliding openings 17 are symmetrically arranged on the outer wall of the main rod 1, and sliders 16 are slidably installed inside each of the two sliding openings 17. The sliders 16 are fixedly connected to the movable rod 2. One end of the threaded rod 18 passes through the main rod 1 and extends outward to be fixedly connected to a rotating plate 20. The outer wall of the threaded rod 18 located between the rotating plate 20 and the main rod 1 is connected to a circular plate 15 via a bearing. A handle 19 is fixedly provided on the outer wall of the circular plate 15. By rotating the rotating plate 20, the rotation of the rotating plate 20 drives the threaded rod 18 to rotate. The rotation of the threaded rod 18 drives the moving rod 2 and the two sliders 16 to move inside the sliding opening 17. The movement of the moving rod 2 drives the fixed rod 3 to move. For some high-temperature forgings, by adjusting the length between the moving rod 2 and the main rod 1, a certain distance is maintained between the worker and the forging to prevent burns.

[0021] The implementation principle of a forging processing hand-held clamp according to an embodiment of this application is as follows: During use, the output end of the cylinder 6 drives the toothed plate 4 to move horizontally. Since the toothed plate 4 is meshed with the sector gears 14 on both sides, the movement of the toothed plate 4 drives the two sector gears 14 to move around the shaft inside the through-hole 12. The movement of the two sector gears 14 drives the two first connecting rods 8 to move. The movement of the first connecting rods 8 drives the second connecting rod 9 to move through the third connecting rod 10, thereby realizing the relative or opposite movement of the two clamping plates 11. By adjusting the two... The distance between the clamping plates 11 allows for clamping and holding forgings of different sizes, making it easier for forging workers to flip and forge the forgings. By rotating the rotating plate 20, the rotation of the rotating plate 20 drives the threaded rod 18 to rotate. The rotation of the threaded rod 18 drives the moving rod 2 and the two sliders 16 to move inside the sliding opening 17. The movement of the moving rod 2 drives the fixed rod 3 to move. For some high-temperature forgings, by adjusting the length between the moving rod 2 and the main rod 1, a certain distance is maintained between the worker and the forging to prevent burns.
