Description

Technical Field

[0001] The utility model belongs to the technical field of iron and steel metallurgy, and particularly relates to a fixed device for a flying shear switcher conduit. Background Art

[0002] In recent years, the high-speed bar production process has been widely used. Compared with ordinary bars, high-speed bars have the advantages of single and double-line high-speed rolling of finished products, high product precision and appearance quality. On the rolling production line, the switcher is usually arranged at the inlet and outlet of the flying shear equipment to guide the rolled pieces. The finished products of double high-speed bars have a high speed. During the rolling of small-sized steel, the linear speed of the flying shear switcher is large, the servo motor rotates and brakes suddenly, and the switcher vibrates greatly. When the switcher vibrates violently, the conduit base is prone to loosen and rotate, and the conduit jumps up and down when the swing arm swings. Seriously, the steel head will hit the shear blade and cause steel stacking. Chinese Utility Model CN 216501545 U discloses a switcher anti-jumping device, which includes a switcher having a steel-passing body; a base disposed at the rear of the switcher; a limiting assembly disposed on the base, which includes a limiting plate and a limiting hole opened on the limiting plate, and the steel-passing body of the switcher passes through the limiting hole. The limiting assembly includes a vertical plate and an inclined plate, the inclined plate is connected to the bottom of the vertical plate or the inclined plate is separated from the vertical plate, the inclined plate is inclined relative to the vertical plate, both the inclined plate and the vertical plate are connected to the base, the upper edge of the inclined plate is used to abut against the steel-passing body of the switcher, and the limiting hole is disposed on the vertical plate. The above device ensures that the switcher eliminates shaking and displacement through the limiting assembly, but it is not convenient to disassemble, which affects the replacement efficiency, thus affecting the production rhythm and reducing the production efficiency. Summary of the Invention

[0003] The technical problem solved by the utility model is the problem that the existing switcher fixing device is inconvenient to press, fix and disassemble.

[0004] The utility model provides a fixed device for a flying shear switcher conduit, which includes an upper fixing clip, a lower fixing clip, a locking screw and a locking nut. Both the upper fixing clip and the lower fixing clip are L-shaped. Arc-shaped clamping surfaces matching the outer wall of the conduit are provided at the inner bending parts of the upper fixing clip and the lower fixing clip. A first groove is provided at the upper end of the lower fixing clip, and connection holes are provided on both side surfaces of the first groove. A second groove is provided at the right end of the lower fixing clip, and a pin shaft is inserted through the second groove. A protrusion is provided at the left end of the upper fixing clip, and a through hole is provided on the protrusion. The protrusion is hinged with the first groove in a matching manner. A vertical through groove is provided on the right side surface of the upper fixing clip. One end of the locking screw is provided with a thread, and the other end is provided with a through hole. The through hole end of the locking screw is sleeved on the pin shaft and can rotate around the pin shaft. The threaded end of the locking screw is matched in the vertical through groove, and the upper end of the locking screw is fastened by the locking nut, so that the conduit is fastened between the upper and lower fixing clips.

[0005] Further, when the locking nut is in the loosened state, the locking screw rotates around the pin shaft and leaves the vertical through groove, realizing quick disassembly.

[0006] Further, the depth of the vertical through groove is 40 mm and the height is 85 mm.

[0007] Further, the radius of the arc-shaped clamping surface is 35 mm.

[0008] The utility model has the following beneficial effects: The fixed device for the flying shear switcher catheter of the utility model makes the catheter fit and press tightly without looseness by arranging arc-shaped clamping surfaces on the inner sides of the upper and lower fixing clips, the stress state is more stable, the shearing mark is centered, avoiding steel piling accidents caused by catheter loosening and self-rotation; When performing maintenance operations by replacing the catheter, loosen the locking nut and turn up the upper fixing clip to remove the catheter, which greatly reduces the time. When replacing the new catheter, ensure that the catheter is placed fittingly on the arc-shaped clamping surface of the lower fixing clip, close the upper and lower fixing clips, screw the locking screw into the vertical through groove, and lock it with the locking nut, reducing the labor intensity of employees, improving work efficiency, and accelerating the production rhythm.
