Description

Technical Field

[0001] This invention relates to the field of short material removal technology for rebar, specifically to a short material removal device for the working platform of a rebar cold shearing machine and its usage method. Background Technology

[0002] Rebar is widely used in civil engineering construction, including houses, bridges, and roads. From large-scale public facilities such as highways, railways, bridges, culverts, tunnels, flood control, and dams, to smaller components like foundations, beams, columns, walls, and slabs in buildings, rebar is an indispensable structural material. With the deepening of urbanization in China, the booming development of infrastructure construction and the real estate industry has created a strong demand for rebar.

[0003] The short material removal process on the working platform of a traditional cold shearing machine for rebar still has the following problems: In rebar production lines, fixed-length rebar is cut using a cold shear machine. After a section of rebar is cut to a multiple length, a significant amount of short material remains on the cold shear machine's work platform, requiring manual cleaning and resulting in high labor intensity for workers. Furthermore, incomplete cleaning of these short materials can lead to them flowing into subsequent processes, affecting the normal operation of downstream equipment and causing malfunctions. Summary of the Invention

[0004] Technical Objective: To address the aforementioned technical problems, this invention proposes a short material removal device for the working platform of a cold shearing machine for rebar and its usage method. This solves the problems of high labor intensity, incomplete removal of short materials, and disruption to the normal operation of subsequent equipment caused by manually cleaning short materials on the working platform of the cold shearing machine, which can lead to equipment failure.

[0005] Technical solution: To achieve the above technical objectives, the present invention employs the following technical means: A short material removal device for the working platform of a cold shearing machine for rebar is provided. The short material removal device is installed on the body of the cold shearing machine and includes a lifting and rotating mechanism and a scraper. The lifting and rotating mechanism drives the scraper to lift and rotate in order to remove short materials on the working platform of the cold shearing machine body. The lifting and rotating mechanism includes: The bushing is fixed to the cold shear machine body via the bushing base; A rotating shaft is movably inserted into the bushing and extends out from the bottom of the bushing to connect to the scraper. A cap is fixed at the top of the rotating shaft. A rotating lifting ring is movably fitted onto the rotating shaft. The bushing supports the rotating lifting ring, and the rotating lifting ring supports the cap. The rotating lifting ring has a first inclined surface facing upward near the cap, and the cap has a second inclined surface that fits against the first inclined surface. The first rotary cylinder has its two ends connected to the bushing base and the side wall of the rotating lifting ring respectively via pins. The first rotary cylinder is used to drive the rotating lifting ring to rotate. The second rotary cylinder is connected at both ends to the bushing base and the side wall of the rotary shaft respectively by pins. The second rotary cylinder is used to drive the rotary shaft to rotate. The first rotary cylinder drives the rotary lifting ring to rotate, and pushes the second inclined plane through the first inclined plane to make the cap rise and fall. When the cap lifts the scraper to the horizontal plane above the working platform of the cold shear machine body, the second rotary cylinder drives the rotating shaft to rotate so that the scraper can clean the short material on the working platform of the cold shear machine body.

[0006] Furthermore, the first rotary cylinder includes a first cylinder body and a first piston rod, and the bushing base is fixed with a first cylinder seat at the location corresponding to the first cylinder body. The first cylinder body and the first cylinder seat are connected by a pin. A first conical protrusion is fixed to the side wall of the rotating lifting ring, and the end of the first piston rod is connected to the first conical protrusion by a pin.

[0007] Furthermore, the second rotary cylinder includes a second cylinder body and a second piston rod, and a second cylinder seat is fixed at the bushing base corresponding to the second cylinder body. The second cylinder body and the second cylinder seat are connected by a pin. A second conical protrusion is fixed to the side wall of the rotating shaft near the scraper end, and the end of the second piston rod is connected to the second conical protrusion by a pin.

[0008] Furthermore, the rotating axis is perpendicular to the working platform of the cold shear machine body.

[0009] Furthermore, the bottom end of the rotating shaft is perpendicularly connected to one end of the scraper.

[0010] Furthermore, the top end of the rotating shaft is pinned to the cap.

[0011] A method of using the short material removal device for the working platform of a cold shearing machine for rebar according to claim 1 includes the following steps: Step 1: The first rotary cylinder actuates, pushing the rotating lifting ring to rotate; Step 2: Rotate the lifting ring to make the first inclined surface rotate relative to the second inclined surface of the cap, and push the second inclined surface to lift the cap upward; Step 3: The cap pulls the rotating shaft upward, and when the rotating shaft is pulled upward, the scraper is lifted to above the horizontal plane of the cold shear machine's working platform, the first rotating cylinder stops moving. Step 4: The second rotary cylinder is activated, pushing the rotating shaft to rotate; Step 5: The rotating shaft rotates, causing the scraper to rotate, thereby scraping the short material on the cold shear machine's working platform into the material frame set below the cold shear machine's working platform; Step Six: The first and second rotary cylinders retract together, causing the rotating shaft and scraper to rotate to the starting position.

[0012] Beneficial effects: Because it adopts a dual-cylinder drive system consisting of a first rotary cylinder and a second rotary cylinder, the first rotary cylinder drives the rotating lifting ring to rotate. The rotating lifting ring, through the first inclined plane, pushes the second inclined plane, causing the rotating shaft to rise, thereby pushing the cap to rise. The rise of the cap causes the rotating shaft and the scraper to rise. At this time, the second rotary cylinder drives the rotating shaft to rotate, and the rotation of the rotating shaft causes the scraper to rotate. The scraper scrapes the short material on the cold shear machine's working platform into the material frame below the working platform, realizing the automatic cleaning of short material on the cold shear machine's working platform. This reduces the labor intensity of the operators and avoids the impact on the normal operation of subsequent equipment due to incomplete cleaning of short material. Attached Figure Description

Detailed Implementation

[0014] To make the objectives, technical solutions, and advantages of the invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of the invention.

[0015] See Figures 1-6 A short material removal device for the working platform of a cold shearing machine for rebar is disclosed. The short material removal device is installed on the body of the cold shearing machine and includes a lifting and rotating mechanism and a scraper 1. A material frame is provided below the working platform of the cold shearing machine body. The lifting and rotating mechanism of the short material removal device drives the scraper 1 to lift and rotate, so as to clean the short materials on the working platform of the cold shearing machine body and scrape the short materials into the material frame provided below the working platform of the cold shearing machine body.

[0016] The lifting and rotating mechanism includes: The bushing 10 has its sidewall fixed to the cold shear machine body via the bushing base 2; the bushing is perpendicular to the cold shear machine working platform 10, and the telescopic bushing is located above the horizontal plane of the working platform.

[0017] A rotating shaft 9 is movably inserted into the bushing 10. The rotating shaft 9 can slide within the bushing 10. The rotating shaft 9 extends out from the bottom of the bushing 10 to connect to one end of the scraper handle 1. The rotating shaft 9 is perpendicularly connected to the scraper handle 1.

[0018] A cap 12 is fixed to the top of the rotating shaft 9, and the top of the rotating shaft 9 is pinned to the cap 12. A rotating lifting ring 11 is sleeved on the rotating shaft 9, and the rotating lifting ring 11 can rotate relative to the rotating shaft 9. The bushing 10 supports the rotating lifting ring 11, and the rotating lifting ring 11 supports the cap 12. The rotating lifting ring 11 has an upward-facing surface near the cap 12. Figure 5 As shown in the diagram, the first inclined surface 15 has a second inclined surface 16 that fits downwards. The rotating lifting ring 11 rotates and pushes the second inclined surface 16 upward through the first inclined surface 15, thereby lifting the cap 12 upward. The upward lifting of the cap 12 drives the rotating shaft 9 upward, which in turn drives the scraper 1 upward, thus raising the scraper 1 above the horizontal plane of the cold shear machine's working platform.

[0019] The first rotary cylinder includes a first cylinder body 3 and a first piston rod 4. One end of the first piston rod 4 is movably disposed in the inner cavity of the first cylinder body 3. The bushing base 2 is fixed with a first cylinder seat at the location corresponding to the first cylinder body 3. The end of the first cylinder body 3 away from the first piston rod 4 is connected to the first cylinder seat by a pin. A first conical protrusion 7 is fixed to the outer wall of the rotating lifting ring 11. A pin hole is provided on the first conical protrusion 7. The end of the first piston rod 4 away from the first cylinder body 3 is connected to the pin hole on the first conical protrusion 7 by a pin. The end of the first piston rod 4 away from the first cylinder body 3 can rotate with the first conical protrusion 7 by the pin. The first rotating cylinder pushes the rotating lifting ring 11 to rotate by extending and retracting the first piston rod 4.

[0020] The second rotary cylinder includes a second cylinder body 5 and a second piston rod 6. One end of the second piston rod 6 is movably disposed in the inner cavity of the second cylinder body 5. The bushing base 2 is fixed with a second cylinder seat at the location corresponding to the second cylinder body 5. The end of the second cylinder body 5 away from the second piston rod 6 is connected to the second cylinder seat by a pin. A second conical protrusion 8 is fixed to the side wall of the rotating shaft 9 near the scraper 1. The second conical protrusion 8 is also provided with a pin hole. The end of the second piston rod 6 away from the second cylinder body 5 is connected to the pin hole on the second conical protrusion 8 by a pin. The end of the second piston rod 6 away from the second cylinder body 5 can rotate with the second conical protrusion 8 by the pin. The second rotating cylinder pushes the rotating shaft 9 to rotate by extending and retracting the second piston rod 6. The rotation of the rotating shaft 9 drives the scraper 1 at the lower end of the rotating shaft 9 to rotate. The rotation of the scraper 1 scrapes the short material on the cold shear machine working platform into the material frame set below the cold shear machine working platform.

[0021] The first rotary cylinder drives the rotary lifting ring 11 to rotate, and pushes the second inclined plane 16 through the first inclined plane 15 to make the cap 12 rise and fall. When the cap 12 drives the scraper 1 to rise above the horizontal plane of the cold shear machine body working platform, the second rotary cylinder drives the rotating shaft 9 to rotate so as to drive the scraper 1 to clean the short material on the cold shear machine body working platform.

[0022] This invention relates to a short material removal device for the working platform of a cold shearing machine for rebar, which, when in use: Step 1: The first rotary cylinder actuates, pushing the rotary lifting ring 11 to rotate; Step 2: Rotate the lifting ring 11 to make the first inclined surface 15 rotate relative to the second inclined surface 16 of the cap 12 and push the second inclined surface 16 to lift the cap 12 upward; Step 3: The cap 12 drives the rotating shaft 9 to lift upwards. When the rotating shaft 9 lifts upwards, it drives the scraper 1 to lift upwards to above the horizontal plane of the cold shear machine's working platform, at which point the first rotating cylinder stops moving. Step 4: The second rotary cylinder is activated, pushing the rotating shaft 9 to rotate; Step 5: The rotating shaft 9 rotates, causing the scraper 1 to rotate, thereby scraping the short material on the cold shear machine's working platform into the material frame set below the cold shear machine's working platform; Step 6: The first and second rotary cylinders retract together, causing the rotary shaft 9 and scraper 1 to rotate to the starting position.
