Description

Technical Field

[0001] This utility model relates to a novel wear-resistant and high-temperature resistant guide rocker device for bar and wire rods, belonging to the technical field of steel rolling machinery structure design. Background Technology

[0002] Using a multiple-length flying shear to segment moving finished steel bars according to process requirements is an efficient method for collecting hot-rolled threaded steel bars. The guide lever device is the key equipment for realizing the multiple-length flying shear. The original design of the guide lever had poor heat resistance and was prone to deformation, bending, and breakage due to heat. As the high-temperature red-hot steel passes through the device at high speed, the guide lever device experiences rapid heat wear, leading to lever deformation and process failures, which seriously affect production efficiency and production costs.

[0005] Preferably, the tail lever gun head includes a guide tube and a flange, with the flange fixed to one end of the guide tube and fixedly connected to the flange at the end of the guide tube.

[0006] Preferably, the guide rocker arm device further includes a rocker arm bottom slide structure, which is installed radially on the seamless steel pipe and includes a base and a cover plate. One end of the base and the cover plate are hinged together, and the other end is connected and fixed by a hinge bolt, a pin and a nut.

[0007] Compared with the prior art, the present invention has the following advantages: 1. Reduce wear, deformation, and breakage of the guide rocker arm; 2. Extend the lifespan of the guide rocker arm device and save equipment costs. Attached Figure Description

[0009] The following is in conjunction with the appendix Figure 1-4 Further details of this utility model: A novel wear-resistant and high-temperature resistant guide rocker device for bar and wire rods, such as... Figure 1-2 As shown, the guide rocker arm device mainly consists of a middle guide tube structure, an outer water-cooled cooling tube structure, a bottom slide block structure of the rocker arm, and a tail rocker arm gun head.

[0010] like Figure 1-2 As shown, the intermediate guide tube structure serves as the inlet conduit 1, comprising a flared mouth and a conduit. One end of the flared mouth is inserted into one end of the conduit, and a steel plate 11 is welded at the joint to seal the two. The other end of the conduit is connected to the tail swing rod nozzle. Figure 3-4 As shown, in this embodiment, the tail swing arm gun head includes a guide tube 8 and a flange. The inner diameter of the guide tube 8 is the same as the inner diameter of the guide tube. The flange is installed at one end of the guide tube 8 and is opposite to the flange 9 installed at the end of the guide tube. After the two are assembled, they are fixed by bolts 5, nuts 6 and spring washers 7 passing through the corresponding mounting holes.

[0011] like Figure 1 As shown, the outer water-cooled cooling pipe structure includes a seamless steel pipe 3 and a welded pipe seat 4. The welded pipe seat 4 is located radially on the seamless steel pipe 3 with its open end facing upwards, serving as a cooling circulating water connector. The outer diameter of the seamless steel pipe 3 is larger than the outer diameter of the conduit. Its two open ends are sealed to the outer surface of the conduit by welded steel plates 2, thereby forming a water-cooled space between the seamless steel pipe 3 and the conduit. The outer water-cooled cooling pipe structure and the intermediate guide pipe structure together constitute the swing rod body. A cooling circulating water connector (welded pipe seat 4) is installed at the front and rear ends of the upper part of the outer cooling pipe wall of the guide swing rod body, and its end is provided with external threads.

[0012] like Figure 3As shown, the bottom slide structure of the rocker arm is connected to the cylinder to realize the rocker arm guide and change angle. It is installed in the radial direction of the seamless steel pipe and includes a base 16 and a cover plate 14. The base 16 and one end of the cover plate 14 are hinged. The other end of the cover plate 14 has a through hole for the hinge bolt 15 to pass through. The through hole passes through the upper and lower surfaces of the cover plate 14. One end of the through hole is open and its open end is located at the edge of the cover plate 14. The other end of the base 16 is a double lug structure. A through hole for the pin shaft 17 to pass through is opened at the corresponding position. One end of the hinge bolt 15 is limited to the base 16 by the pin shaft, and the other end is connected and fixed by the nut 12 and the flat washer 13.
