DETAILED DESCRIPTION

[0021] The following will be combined with the drawings of the specification to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Embodiment 1: Combination Figure 1-Figure 3 As shown, the utility model provides a technical solution: a hydraulic shear mechanism with a rotating function, comprising a frame 1, a fixing plate 2 is arranged on the top of the frame 1, and a hydraulic shear assembly 3 is arranged on the fixing plate 2;

[0023] The hydraulic shear assembly 3 includes a slewing bearing 31 rotatably mounted on the fixed plate 2, a U-shaped frame 32 is fixedly connected to the bottom end of the slewing bearing 31, a shearing piece is arranged on the U-shaped frame 32, a second cylinder 37 is arranged on one side of the slewing bearing 31, an output end of the second cylinder 37 is rotatably connected to a mounting plate 39 via a positioning shaft 38, and the mounting plate 39 is fixedly mounted on the slewing bearing 31;

[0024] The shearing piece includes an upper blade 34 and a lower blade 33 located at the upper and lower ends of the inner side of the U-shaped frame 32. The lower blade 33 is fixedly mounted on the U-shaped frame 32. A first cylinder 35 is fixedly connected to the top of the slewing support bearing 31. The output end of the first cylinder 35 penetrates the U-shaped frame 32 and is fixedly connected to the upper blade 34.

[0025] The second cylinder 37 is rotatably connected with a trunnion foot seat 36 , and the trunnion foot seat 36 is fixedly mounted on the fixing plate 2 .

[0026] In the embodiment of the present invention, the second cylinder 37 is turned on, the positioning shaft 38 and the mounting plate 39 are cooperated to drive the slewing support bearing 31 to rotate on the fixed plate 2, so that the slewing support bearing 31 drives the U-shaped frame 32, the lower blade 33 and the upper blade 34 to rotate synchronously, thereby changing the shearing angle. When the sheared object is located between the lower blade 33 and the upper blade 34, the upper blade 34 is driven to move to the side of the lower blade 33 by turning on the first cylinder 35, so that the lower blade 33 cooperates with the upper blade 34 to shear the sheared object.

[0027] By starting the second cylinder 37 and combining the coordinated operation of the positioning shaft 38 and the mounting plate 39, the slewing support bearing 31 can be fixed on the fixed plate 2 for smooth rotation. This process realizes the synchronous rotation of the U-shaped frame 32, the lower blade 33 and the upper blade 34 driven by the slewing support bearing 31. Therefore, the user of the equipment can adjust the shearing angle according to the needs to meet the processing requirements of different sheared objects. When the sheared object is located between the lower blade 33 and the upper blade 34, starting the first cylinder 35 can drive the upper blade 34 to move toward the side of the lower blade 33. This design enables the lower blade 33 and the upper blade 34 to work together to accurately shear the sheared object. This innovative design greatly improves the shearing efficiency and shearing accuracy of the equipment and meets the processing requirements of various types of sheared objects.

[0028] Embodiment 2: Combination Figure 3 As shown, on the basis of the first embodiment, the fixed plate 2 includes a mounting seat 21 fixedly mounted on the frame 1, a slewing support bearing 31 is rotatably mounted on the mounting seat 21, a fixing frame 22 is fixedly mounted on both sides of the mounting seat 21, and a buffer 23 is fixedly connected to the fixing frame 22;

[0029] A limiting plate 310 is fixedly connected to one side of the top of the mounting plate 39 . The rotation position of the limiting plate 310 is located between the two buffers 23 . The buffer 23 is installed on the mounting seat 21 . The buffer 23 can be composed of a telescopic rod and a damping buffer spring, which can buffer the limiting plate 310 .

[0030] In an embodiment of the present invention, when the second cylinder 37 drives the slewing support bearing 31 to rotate, the slewing support bearing 31 drives the limit plate 310 to rotate synchronously. Buffers 23 are provided on both sides of the limit plate 310. When the limit plate 310 rotates to the maximum position, the buffer 23 will play a role to limit and buffer the rotation of the limit plate 310. This treatment method helps to prevent the limit plate 310 from being damaged due to excessive impact during rotation, thereby extending the service life of the equipment. In summary, the synergistic effect between the second cylinder 37, the slewing support bearing 31, the limit plate 310 and the buffer 23 ensures the stability and reliability of the mechanical equipment during operation.

[0031] The working principle of the hydraulic shear mechanism with a rotating function is: when the object to be sheared is located between the lower blade 33 and the upper blade 34, the first cylinder 35 is activated to drive the upper blade 34 to move toward the side of the lower blade 33. This design enables the lower blade 33 and the upper blade 34 to work together to perform precise shearing of the object to be sheared;

[0032] When shearing at different angles is required, by starting the second cylinder 37 and combining the coordinated operation of the positioning shaft 38 and the mounting plate 39, the slewing support bearing 31 can be fixed on the fixed plate 2 and rotate smoothly. This process realizes the synchronous rotation of the U-shaped frame 32, the lower blade 33 and the upper blade 34 driven by the slewing support bearing 31. Therefore, the equipment user can adjust the shearing angle according to the needs to meet the processing requirements of different shearing objects.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
