DETAILED DESCRIPTION

[0022] like Figure 1-4 As shown, a forging hydraulic press proposed by the utility model includes a frame 1, a hydraulic assembly 2, a clamping assembly 6, a translation assembly 4 and a flip assembly 5. A forging table 3 is arranged on the frame 1. The hydraulic assembly 2 is arranged on the frame 1 to perform hydraulic forging on the forging. The clamping assembly 6 is arranged between the hydraulic assembly 2 and the forging table 3, and the forging is clamped from the upper and lower sides and the left and right sides of the forging through the clamping plate 66. The translation assembly 4 is arranged on the frame 1 to drive the clamping assembly 6 to move forward and backward. The flip assembly 5 is arranged on the translation assembly 4 to drive the clamping assembly 6 to flip.

[0023] Further explanation, the hydraulic assembly 2 includes a plurality of vertical rods 21 arranged on the frame 1; a top plate 22 is commonly arranged at the upper ends of the plurality of vertical rods 21; a hydraulic cylinder 23 is arranged on the top plate 22; a hammer forging plate 24 is connected to the telescopic end of the hydraulic cylinder 23; and the hammer forging plate 24 is opposite to the forging table 3. The forgings can be hydraulically forged.

[0024] Further, a plurality of sliding sleeves 25 are provided on the hammer forging plate 24; the plurality of sliding sleeves 25 are opposite to the plurality of vertical rods 21 one by one, and are respectively slidably connected with the corresponding vertical rods 21. This makes the hammer forging plate 24 more stable when pressed down, and avoids the hammer forging plate 24 from tilting and affecting the forging quality.

[0025] Further explanation, the translation assembly 4, the flip assembly 5 and the clamping assembly 6 are all symmetrically arranged about the forging table 3. The translation assembly 4 includes a fixed block 41 symmetrically arranged at the lower end of the frame 1; a threaded rod 42 is rotatably connected between the two fixed blocks 41; one end of the threaded rod 42 is connected to the driving end of a driving mechanism 43 arranged on the fixed block 41, and a slider 44 is also threadedly connected thereto. The clamping assembly 6 can be driven to approach or move away from the forging. When it is close to the forging, it can be convenient to clamp the forging, and when it is far away from the forging, the clamping assembly 6 can be prevented from affecting the forging process.

[0026] Further explanation, the frame 1 is provided with a slide slot 51; the flip assembly 5 includes a telescopic mechanism 1 52 arranged at the upper end of the slider 44; the fixed end of the telescopic mechanism 1 52 is slidably connected to the slide slot 51, and the telescopic end is connected to a fixed frame 53; a driving mechanism 2 54 is provided on the fixed frame 53; and the driving end of the driving mechanism 2 54 is connected to a flip frame 55. The flip assembly 5 can drive the forging to flip, so that each surface of the forging can be forged, which meets different forging requirements and improves the practicality of the device.

[0027] Further explanation, the clamping assembly 6 includes a telescopic mechanism 2 61 arranged on the driving mechanism 2 54; the driving end of the telescopic mechanism 2 61 is connected to a push plate 62; the push plate 62 is symmetrically rotatably connected to a connecting rod 1 63; the other ends of the two connecting rods 1 63 are both rotatably connected to connecting rods 2 64; the other ends of the two connecting rods 2 64 are both connected to a clamping plate 66, and are both rotatably connected to a fixed plate 65 arranged on the driving mechanism 2 54; the angle between the connecting rod 2 64 and the clamping plate 66 is an obtuse angle. When clamping the forging, the clamping assembly 6 on one side can clamp the left and right ends of the forging, and the clamping assembly 6 on the other side can clamp the upper and lower ends of the forging, so that the clamping assembly 6 can clamp the forging more tightly, avoid the clamping assembly 6 from slipping during the flipping process, and cause the clamping assembly 6 to be damaged, thereby improving the yield rate of the forging.

[0028] Further, the forging table 3 is rotatably arranged on the frame 1 and is coaxially connected to the driving end of the driving mechanism 3 301 arranged on the frame 1. The driving mechanism 3 301 can drive the forging table 3 to rotate, so that the forging on the forging table 3 can be rotated to an angle convenient for the clamping assembly 6 to clamp it.

[0029] The working principle of the utility model is as follows: when working, the forging is first placed on the forging table 3. When the forging needs to be turned over, the driving mechanism 3 301 is first started to drive the forging table 3 to rotate, and the forging is adjusted to a convenient clamping angle. Then the driving mechanism 1 43 is started to drive the threaded rod 42 to rotate, thereby driving the turning assembly 5 and the clamping assembly 6 to approach the forging. Then the telescopic mechanism 2 61 on the clamping assembly 6 on one side is started, so that the telescopic end of the telescopic mechanism 2 61 extends to drive the connecting rod 1 63, the connecting rod 2 64 and the clamping plate 66 to rotate, so that the two clamping plates 66 clamp the forging from the left and right ends respectively. Then the corresponding telescopic mechanism 1 52 is started to lift the forging and vacate the lower end of the forging. Then the telescopic mechanism 2 61 on the clamping assembly 6 on the other side is started, so that the clamping plates 66 on it clamp the forging from the upper and lower ends respectively. Finally, the two driving mechanisms 2 54 are started to drive the two turning frames 55 to turn over, thereby driving the forging to turn over. After the turning is completed, the clamps 66 at the upper and lower ends after the turning are first loosened, and then the clamps 66 at the two ends of the turning are loosened to make the forging fall onto the forging table 3. Finally, the hydraulic cylinder 23 is started to drive the hammer forging plate 24 to press down to forge the forging.

[0030] The implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
