[0002] In recent years, hot-rolled bars have been widely used in civil buildings, industrial buildings, bridge construction, petroleum industry, high-rise buildings, underground railways and mine tunnels and industrial steel structures due to their excellent mechanical properties. In particular, the bar market is extremely hot, and the demand for large bars has also surged.

[0003] After hot-rolled bars are rolled, a pusher device is needed to push the bars to the next process. The current bar pusher device has the following problems: First, the pusher rod needs to be replaced after it wears out, which results in high maintenance costs. Second, the pusher rod lacks a guide component during its movement. The large range of shaking during its movement can cause the pusher end to scratch the bar and accelerate the wear of the pusher rod. Summary of the Invention

[0042] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0043] like Figures 1 to 6 As shown, a hot-rolled bar feeding device includes:

[0044] Push rod 1, which is movably connected to base 8;

[0045] A guide assembly that guides the movement direction of the push rod 1;

[0046] A drive assembly, the output end of which is connected to the push rod 1 via an adjustment assembly 4, the length of which is adjustable;

[0047] Push plate 2, which is detachably connected to the end of push rod 1 away from the drive assembly.

[0048] The guide assembly includes three guide wheels 3, each guide wheel 3 being rotatably connected to a mounting base 301, and the mounting base 301 being fixedly connected to the base 8;

[0049] Two of the guide wheels 3 support the lower end face of the push rod 1, while the other limits the upper end face of the push rod 1. The contact surface between the guide wheel 3 and the push rod 1 is an arc to ensure that the push rod does not wobble from side to side during forward and backward movement. The lower guide wheel 3 supports the push rod 1, while the upper guide wheel 3 has a gap of 1-2mm with the push rod 1 to ensure that the push rod 1 does not jam during movement.

[0050] The push rod 1 is a cylindrical rod, and the outer wall of the guide wheel 3 has an annular groove 302 that matches the cylindrical rod. The push rod 1 is located inside the annular groove 302. There is a gap between the push rod 1 and the guide wheel 3 that limits the upper end face of the push rod 1.

[0051] The drive assembly includes a hydraulic cylinder 5 and a first swing arm 6. The lower end of the first swing arm 6 is hinged to the base 8, the housing of the hydraulic cylinder 5 is hinged to the base 8, and the output shaft of the hydraulic cylinder 5 is hinged to a second swing arm 9. The upper end of the first swing arm 6 is hinged to one end of an adjusting assembly 4, and the other end of the adjusting assembly 4 is hinged to a push rod. The hydraulic cylinder 5 is assembled using a central trunnion swing-type hydraulic cylinder 5, which is more flexible during operation. The trunnion bearing seat of the hydraulic cylinder 5 and the base 8 are connected by a concave-convex surface, making the hydraulic cylinder 5 more stable during operation.

[0052] The lower ends of the first swing arm 6 and the second swing arm 9 are fixedly connected to the hinge shaft 7, and the hinge shaft 7 is hinged to the base 8. There are multiple first swing arms 6, and each first swing arm 6 is provided with a push rod 1, and the axes of the push rod 1 are arranged parallel to each other. The adjustment assembly 4 includes two hinge rings 401 and an adjustment tube 402. One hinge ring 401 is fixed with a left-hand threaded post 404, and the other hinge ring 401 is fixed with a right-hand threaded post 405. The inner side of one end of the adjustment tube 402 is provided with a left-hand thread, and the inner side of the other end is provided with a right-hand thread. The two ends of the adjustment tube 402 are threadedly connected to the left-hand threaded post 404 and the right-hand threaded post 405, respectively. One hinge ring 401 is hinged to the upper end of the swing arm, and the other hinge ring 401 is hinged to the end of the push rod 1 away from the push plate 2. By rotating the adjusting tube 402, the positions of the two hinge rings 401 can be adjusted, thereby adjusting the horizontal position of the push plate 2, so that the two push plates 2 can be aligned, improving the stability of the pushing action.

[0053] The regulating tube 402 is provided with a socket 403, and the axis of the socket 403 is set perpendicular to the axis of the regulating tube 402.

[0054] The push plate 2 is a structural component made of wear-resistant steel, which extends the service life of the device.

[0055] The pusher rod 1 is fixedly provided with a mounting plate 101 corresponding to the pusher plate 2. Side plates 202 corresponding to the mounting plate are fixedly provided on both sides of the pusher plate 2. The distance between the two side plates 202 matches the width of the mounting plate 101. A second through hole 103 is opened on the mounting plate 101, and a first through hole is opened on the pusher plate 2. A mounting bolt 10 is installed in the first through hole, and the mounting bolt 10 passes through the first and second through holes 103 and is threadedly connected to a nut. The two side plates 202 serve to position the pusher plate 2, improving the efficiency of installation and replacement. When the pusher plate 2 wears out after prolonged use, it can be replaced by loosening the mounting bolt 10, making the process convenient.

[0056] The push plate 2 is provided with a V-shaped groove 201, and the second through hole 103 is a strip-shaped through hole with its length direction perpendicular to the ground. The upper and lower ends of the mounting plate 101 are fixed with adjusting plates 102. The push plate 2 is located between the two adjusting plates 102. The lower adjusting plate 102 has two threaded holes, and the upper adjusting plate 102 has one threaded hole. The first threaded hole is internally threaded with a support bolt 11, which supports the lower end face of the push plate 2. The second threaded hole is internally threaded with a limit bolt 12, which limits the upper end face of the push plate 2. The second threaded hole corresponds to the two first threaded holes. The V-groove 201 serves a certain positioning function, preventing the round bar from shaking when pushing it and improving the stability of the pushing process. Loosening the mounting bolt 10, support bolt 11 and limit bolt 12 can adjust the height of the push plate 2 and thus adjust the position of the V-groove 201, which is suitable for pushing round bars of different diameters. The support bolt 11 and limit bolt 12 reduce the force on the mounting bolt 10 and prevent the mounting bolt 10 from bending during use.

[0057] Work process:

[0058] When this solution is implemented, when the bar reaches the left side of the push plate 2, the output shaft of the hydraulic cylinder 5 extends, driving the first swing arm 6, the hinge shaft 7, and the second swing arm 9 to rotate. The second swing arm 9 drives the push rod 1 to move through the adjustment component 4. The push plate 2 at the front end of the push rod 1 pushes the bar to move. The guide component plays a guiding role, making the movement of the push rod 1 more stable. The push plate can be detachably connected to the push plate, which is convenient for replacement and improves maintenance efficiency.
