Description

Technical Field

[0001] The utility model relates to the technical field of high-speed flying shears, in particular to a high-speed flying shear blade with an adjustment function. Background Art

[0002] In the modern metallurgy and metal processing industry, flying shears are widely used as a key equipment in continuous production lines to achieve fast and accurate cutting of moving metal plates, strips or tubes. Traditional flying shear designs mostly focus on stability and cutting accuracy under high-speed operation, but have limitations in flexibility to adapt to materials of different thicknesses. Most of the roller-type high-speed flying shear devices on the market currently have fixed blade gaps or only provide limited adjustment capabilities, mainly by adjusting the distance between the two rollers to match the processing materials of different thicknesses.

[0003] However, when the thickness of the processed material increases significantly and exceeds the thickness design limit of the flying shear blade itself, even if the roller spacing is adjusted so that the material can continue to be transferred between the two rollers, effective cutting operation cannot be ensured. This is because when the material thickness is much greater than the thickness of the shear blade, the shear blade cannot penetrate the material to complete the cutting, resulting in cutting failure. This problem not only limits the flying shear equipment's ability to handle thick materials, but may also cause adverse consequences such as equipment jamming and increased blade wear. In severe cases, it may even interrupt the production process, affecting overall production efficiency and cost control. No effective solution has yet been proposed for the problems in the relevant technology. Therefore, it is necessary to propose a high-speed flying shear blade with an adjustment function to solve the above-mentioned problems. Utility Model Content

[0004] In view of the problems in the related technology, the utility model proposes a high-speed flying shear blade with an adjustment function to overcome the above technical problems existing in the existing related technology.

[0005] To this end, the specific technical solutions adopted by the utility model are as follows:

[0006] A high-speed flying shear blade with an adjustment function comprises a telescopic adjustment frame, transmission motor 1 is fixedly installed on both sides of the inner wall of the telescopic adjustment frame, a protective shell is fixedly connected to the transmission shaft of the transmission motor 1, a transmission roller is fixedly installed at one end of the protective shell, a transmission shell is fixedly installed at the end of the transmission roller, a transmission motor 2 is fixedly installed inside the transmission shell, a threaded transmission rod is fixedly connected to the transmission shaft of the transmission motor 2, conical transmission blocks are threadedly connected at both ends of the surface of the threaded transmission rod, a positioning ring is rotatably connected at the center of the surface of the threaded transmission rod, a telescopic spring is fixedly connected to the surface of the positioning ring, a trapezoidal extrusion plate is fixedly connected to one end of the telescopic spring, an adjusting shear blade is fixedly connected to the end of the trapezoidal extrusion plate, an adjusting hole is opened on the surface of the transmission roller, and the adjusting shear blade is slidably installed in the adjusting hole.

[0007] Furthermore, in order to change the distance between the two transmission rollers on the telescopic adjustment frame, the bottom end of the telescopic adjustment frame is fixedly connected to a support plate, transmission tubes are rotatably installed on both sides of the surface of the support plate, a lifting threaded rod is connected to the inner thread of the transmission tube, and the top of the telescopic adjustment frame is fixedly connected to the lifting plate, and the top of the lifting threaded rod is fixedly connected to the bottom surface of the lifting plate.

[0008] Furthermore, in order to enable the conical transmission block to push the trapezoidal extrusion plate after it moves, the inclined surfaces on both sides of the trapezoidal extrusion plate match the conical surfaces of the conical transmission block.

[0009] Furthermore, in order to realize rotational support for the threaded transmission rod, one end of the threaded transmission rod is rotationally connected to the inner wall of the protective shell.

[0010] Furthermore, in order to realize installation and disassembly of the adjustable flying shear in the transmission drum, one end of the protective housing and the transmission housing is fixedly connected with a loading and unloading ring, and the loading and unloading ring is fixedly installed on both ends of the transmission drum by bolts.

[0011] Furthermore, in order to control each motor in the device, a multi-control switch is fixedly installed on one side surface of the telescopic adjustment frame.

[0012] Furthermore, in order to facilitate the twisting of the transmission tube, a twisting block is fixedly connected to the surface of the transmission tube.

[0013] The beneficial effects of the utility model are as follows: the transmission motor 2 in the transmission housing drives the threaded transmission rod to rotate, so that the conical transmission blocks at both ends of the surface of the threaded transmission rod move relatively, and the trapezoidal extrusion plate at one end of the adjusting shear blade is squeezed, so that the trapezoidal extrusion plate drives the adjusting shear blade to move telescopically on the surface of the transmission roller, thereby changing the thickness of the adjusting shear blade exposed on the surface of the transmission roller, which is used for adjusting and cutting processing materials of different thicknesses, significantly enhancing the adaptability of the flying shear in cutting materials of different thicknesses, increasing the processing range of the equipment, avoiding the replacement of equipment, and thus improving the overall production efficiency and continuous operation capacity.

The inclined surfaces on both sides of the trapezoidal extrusion plate 11 cooperate with the conical surfaces of the conical transmission blocks 8. The two conical transmission blocks 8 are moved closer to each other by the rotation of the threaded transmission rod 7, and the trapezoidal extrusion plate 11 and the adjusting shear blade 12 are squeezed while moving, so that the trapezoidal extrusion plate 11 drives the adjusting shear blade 12 to slide out of the adjusting hole 13.

[0025] like Figure 1-Figure 4 As shown, the bottom end of the telescopic adjustment frame 1 is fixedly connected with a support plate 14 for stably supporting the telescopic adjustment frame 1; a pair of transmission tubes 15 are rotatably installed on both sides of the surface of the support plate 14, and the transmission tube 15 is internally threaded with a lifting threaded rod 16, and the top of the telescopic adjustment frame 1 is fixedly connected with a lifting plate 17, and the top of the lifting threaded rod 16 is fixedly connected to the bottom surface of the lifting plate 17.
