[0001] The utility model relates to the technical field of shearing machine blade disassembly and assembly, in particular to a shearing machine blade disassembly and assembly device. Background Art

[0002] A shearing machine uses a blade that moves back and forth linearly relative to another to shear metal sheets. Using a moving upper blade and a fixed lower blade, with a reasonable gap between the blades, the machine applies shearing force to metal sheets of various thicknesses, breaking and separating the sheets to the desired dimensions. Shearing machines are a type of forging machinery primarily used in the metalworking industry. They are widely used in aviation, light industry, metallurgy, chemicals, construction, shipbuilding, automotive, electric power, electrical appliances, and interior decoration, providing specialized machinery and complete equipment.

[0003] When shearing channel steel, an opening with the same cross-section as the channel steel is often opened on the fixed blade, so that the channel steel can be inserted into the opening, and then the moving blade is controlled to shear the channel steel; however, due to the different sizes of channel steels, when processing different channel steels, the opening on the fixed blade needs to be changed accordingly, and the fixed blade needs to be replaced. For this reason, a shearing machine blade disassembly and assembly device is urgently needed, which can conveniently and quickly disassemble and replace the fixed blade. Utility Model Content

[0026] In this utility model, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium, internal communication between two components, or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0027] See also Figure 1-Figure 3The embodiment of the utility model provides: a shearing machine blade disassembly and assembly device, comprising: a fixed blade 1, a frame 2, a pushing ring 3 and a pushing mechanism 4; the fixed blade 1 is provided with a channel steel groove with the same cross-section as the channel steel, and the opening of the channel steel groove should be slightly larger than the cross-section of the channel steel, so that the channel steel can be easily inserted into the channel steel groove; the frame 2 is provided with a mounting groove 21 that matches the fixed blade 1, and a stop edge 22 is provided in the edge of one end of the mounting groove 21; the pushing ring 3 is arranged on the side of the fixed blade 1 away from the stop edge 22; the pushing mechanism 4 can control the pushing ring 3 to slide in the length direction of the mounting groove 21, so that the pushing ring 3 abuts against or separates from the fixed blade 1.

[0028] During specific implementation, the fixed blade 1 is placed into the installation groove 21; the pushing mechanism 4 is controlled to act, and the pushing mechanism 4 drives the pushing ring 3 to move toward the fixed blade 1, so as to apply a thrust to the fixed blade 1, and in cooperation with the blocking edge 22, the fixed blade 1 is fixed; and when the fixed blade 1 needs to be disassembled and assembled, it is only necessary to control the pushing ring 3 to separate from the fixed blade 1 through the pushing mechanism 4; in this way, the fixed blade 1 can be replaced simply and quickly, so that the shearing machine can adapt to channel steels of different models and sizes.

[0029] See also Figure 1-Figure 3 In other embodiments, the push mechanism 4 includes: a sleeve 41, a flange 42, and a threaded rod 43; the sleeve 41 is slidably plugged into the mounting slot 21, one end of the sleeve 41 is fixedly connected to the push ring 3, and the other end of the sleeve 41 is installed with a flange 42; the threaded rod 43 passes through the flange 42 and is threadedly connected to the flange 42; and the threaded rod 43 is arranged along the length direction of the mounting slot 21 and is rotatably connected to the frame 2. During specific implementation, the threaded rod 43 is rotated, and the threaded rod 43, under the action of the thread, controls the push ring 3 to approach the fixed blade 1 through the flange 42 and the sleeve 41, thereby achieving abutment and fixation of the fixed blade 1. By rotating the threaded rod 43 in the opposite direction, the push ring 3 can be controlled to move away from the fixed blade 1 through the flange 42 and the sleeve 41, so that the push ring 3 slides out of the mounting slot 21, and the fixed blade 1 can be replaced.

[0030] See also Figure 1-Figure 3 In other embodiments, multiple threaded rods 43 are provided around the sliding sleeve 41. The provision of multiple threaded rods 43 allows for pressing at multiple locations on the sliding sleeve 41, thereby ensuring a more stable thrust applied by the push ring 3 to the fixed blade 1. Furthermore, a transmission mechanism 5 is included that can drive the multiple threaded rods 43 to rotate synchronously. The provision of the transmission mechanism 5 allows for simultaneous rotation of multiple threaded rods 43, making replacement of the fixed blade 1 more convenient and quick.

[0031] See also Figure 1-Figure 3In other embodiments, the transmission mechanism 5 can be the following structure including: a sprocket 51 and a chain 52; a sprocket 51 is coaxially fixed on each threaded rod 43; and multiple sprockets 51 are connected by a chain 52. In a specific implementation, when one of the threaded rods 43 is rotated, the other threaded rods 43 are driven to rotate synchronously under the action of the sprocket 51 and the chain 52, thereby reducing the number of times the threaded rods 43 are rotated, thereby making it more convenient and quick to disassemble and assemble the fixed blade 1. Furthermore, a motor is also included, which can drive one of the threaded rods 43 to rotate. Through the setting of the motor, the forward and reverse rotation of one of the threaded rods 43 can be controlled by the motor. Furthermore, the transmission mechanism 5 can also be a belt drive.
