Description

Technical Field

[0001] The utility model relates to the technical field of cold shearing, in particular to a cold shearing tail sweeping mechanism. Background Art

[0002] Cold shearing is to cut the steel on the cooling bed into the length specified by the user. The shearing process involves cutting the head and tail, as well as the processing of the head and tail materials. The processing of the head and tail materials directly affects the working efficiency and failure rate of the cold shearing, and even affects the normal shearing, so the processing of the head and tail materials is particularly important.

[0003] A cold shear tail sweeping mechanism is typically a device in a cold shear machine that removes residual material or debris after shearing to maintain a clean work area and ensure a smooth production process. Existing cold shear tail sweeping mechanisms, when handling head and tail stock, can become stuck in the gap between the sweeping guide plate and the lower shear blade after shearing, as the head and tail of steel are typically not smoothly rounded. This can affect the transport and handling of the head and tail stock. Utility Model Content

[0004] The utility model is made to solve the above technical problems, and its purpose is to provide a cold shear tail sweeping mechanism which can prevent the head and tail materials from being stuck in the gap when cleaning.

[0005] In order to achieve the above-mentioned purpose, the utility model provides a cold shear tail sweeping mechanism, which is installed on the shear blade base, including a tail sweeping guide plate, the lower end of which is rotatably connected to the shear blade base, and the upper surface is higher than the upper surface of the lower shear blade; a hydraulic cylinder, one end of which is rotatably connected to the end of the tail sweeping guide plate away from the lower shear blade, driving the tail sweeping guide plate to rotate when extending and retracting; a support, which is fixedly connected to the shear blade base and is rotatably connected to the tail sweeping guide plate.

[0006] Preferably, it further comprises a first rotating shaft, which is located at the connection between the tail sweeping guide plate and the hydraulic cylinder; and a second rotating shaft, which is rotatably connected to the support and the tail sweeping guide plate.

[0007] Preferably, the sweeping guide plate includes a guide plate body, a connecting plate and a guide plate bracket, the connecting plate is connected to the guide plate body and the guide plate bracket, and the guide plate body is arranged parallel to the guide plate bracket; the first rotating shaft and the second rotating shaft are both arranged on the guide plate bracket.

[0008] Preferably, an elastic buffer is further included, which is installed between the guide plate body and the guide plate bracket.

[0009] Preferably, the tail sweep guide plate further comprises a fixing column installed between the guide plate body and the guide plate bracket, and the elastic buffer is sleeved on the fixing column.

[0010] Preferably, the guide plate body, the connecting plate and the guide plate bracket are welded together.

[0011] Preferably, the surface of the guide plate body is provided with a wear-resistant coating.

[0012] Preferably, the sweeping guide plate rotates around the first rotation axis at an angle less than 90 degrees.

[0013] Preferably, it further comprises a limiting member installed on the second rotating shaft.

[0014] Preferably, it further comprises a collecting device, the opening of which faces the tail sweeping guide plate, and when the tail sweeping guide plate rotates, the projection of one end of the tail sweeping guide plate falls into the range of the collecting device.

[0015] According to the above description and practice, the cold shear tail sweeping mechanism provided by the present invention is installed on the shear blade base, wherein the cold shear tail sweeping mechanism includes a tail sweeping guide, a hydraulic cylinder and a support, the steel and the head and tail materials move on the tail sweeping guide, the hydraulic cylinder supports and drives and limits the tail sweeping guide to rotate and dump the head and tail materials together with the support. The lower end of the tail sweeping guide is rotatably connected to the shear blade base, and the upper surface is higher than the upper surface of the lower shear blade. On the one hand, it prevents the steel from touching the lower shear blade when the steel moves along the tail sweeping guide toward the shear blade base, causing damage to the steel; on the other hand, due to the certain gap between the tail sweeping guide and the shear blade base, it prevents the head and tail materials with sharp corners from getting stuck in the gap when the steel moves along the tail sweeping guide away from the shear blade base, and falling when the tail sweeping guide rotates, affecting the normal operation of other devices in the cold shear mechanism. One end of the hydraulic cylinder is rotatably connected to the end of the sweep guide plate, away from the lower shear blade. This drives the sweep guide plate to rotate during extension and retraction. When the hydraulic cylinder extends, it supports the sweep guide plate, allowing the steel to move along the sweep guide plate toward the shear blade base. When the hydraulic cylinder retracts, it drives the sweep guide plate to rotate, completing the dumping of the head and tail stock. The support, fixedly connected to the shear blade base and rotatably connected to the sweep guide plate, limits the sweep guide plate's rotation angle, preventing excessive sweep guide rotation from affecting the normal operation of the entire cold shear mechanism.

[0023] The utility model discloses a cold shear tail sweeping mechanism, which is installed on the shear blade base 10. Please refer to Figures 1 to 4In some embodiments, the cold shearing tail sweeping mechanism includes a sweeping guide plate 1, a hydraulic cylinder 2, and a support 3. The steel and the head and tail materials move on the sweeping guide plate 1. The hydraulic cylinder 2 supports the sweeping guide plate 1 and drives and restricts the sweeping guide plate 1 from rotating and dumping the head and tail materials together with the support 3. The lower end of the sweeping guide plate 1 is rotatably connected to the shear blade base 10, and the upper surface is higher than the upper surface of the lower shear blade 20. On the one hand, it prevents the steel from touching the lower shear blade 20 and causing damage to the steel when the steel moves along the sweeping guide plate 1 toward the shear blade base 10; on the other hand, since there is a certain gap between the sweeping guide plate 1 and the shear blade base 10, it prevents the head and tail materials with sharp corners from getting stuck in the gap when the steel moves along the sweeping guide plate 1 away from the shear blade base 10, and falling when the sweeping guide plate 1 rotates, affecting the normal operation of other devices in the cold shearing mechanism. One end of the hydraulic cylinder 2 is rotatably connected to the end of the sweep guide plate 1 away from the lower shear blade 20. When the hydraulic cylinder 2 is extended, it drives the sweep guide plate 1 to rotate. When the hydraulic cylinder 2 is extended, it is used to support the sweep guide plate 1, at which time the steel moves along the sweep guide plate 1 toward the shear blade base 10. When the hydraulic cylinder 2 is retracted, it drives the sweep guide plate 1 to rotate to complete the dumping of the head and tail of the material. The support 3 is fixedly connected to the shear blade base 10 and is rotatably connected to the sweep guide plate 1, which limits the rotation angle of the sweep guide plate 1, preventing the sweep guide plate 1 from rotating too much and affecting the normal operation of the entire cold shear mechanism. Specifically, the support 3 is fixedly connected to the shear blade base 10. On the one hand, it supports the sweeping guide plate 1 to prevent the sweeping guide plate 1 from moving toward the shear blade base 10 under the force of the steel, causing the steel and the head and tail materials to fall from the sweeping guide plate 1 and affect the working efficiency of the entire cold shearing mechanism; on the other hand, it is used to assist and limit the rotation of the sweeping guide plate 1 to avoid the sweeping guide plate 1 from rotating at too large an angle and causing deflection, which causes the sweeping guide plate 1 to be unable to return to its initial position normally.

[0024] In some embodiments, the cold shearing tail sweeping mechanism further includes a first rotating shaft 4 and a second rotating shaft 5, wherein the first rotating shaft 4 is located at the connection between the tail sweeping guide plate 1 and the hydraulic cylinder 2. When the hydraulic cylinder 2 contracts, the tail sweeping guide plate 1 rotates around the first rotating shaft 4 and dumps the head and tail materials. When the hydraulic cylinder 2 extends, the tail sweeping guide plate 1 rotates around the first rotating shaft 4 and approaches the shear blade base 10 for transporting steel to the shear blade base 10. The second rotating shaft 5 is rotatably connected to the support 3 and the tail sweeping guide plate 1, so that the tail sweeping guide plate 1 can move relative to the support 3. Under the premise of not affecting the normal rotation of the tail sweeping guide plate 1, the rotation angle of the tail sweeping guide plate 1 is limited to prevent the tail sweeping guide plate 1 from rotating too much and affecting the subsequent resetting of the tail sweeping guide plate 1.

[0025] To ensure the overall stability of the tail sweep guide 1 and prevent unnecessary friction on steel materials during transportation on the tail sweep guide 1, in some embodiments, the tail sweep guide 1 includes a guide body 11, a connecting plate 12, and a guide bracket 13. The connecting plate 12 is connected to the guide body 11 and the guide bracket 13, connecting the guide body 11 and the guide bracket 13 into a single unit. The guide body 11 and the guide bracket 13 are arranged parallel to each other to ensure that the guide body 11 and the guide bracket 13 always maintain consistent alignment during rotation. The first rotating shaft 4 and the second rotating shaft 5 are both arranged on the guide plate bracket 13. On the one hand, it prevents the steel and the head and tail materials from exerting force on the first rotating shaft 4 and the second rotating shaft 5 when being transported on the guide plate body 11, thereby causing the first rotating shaft 4 and the second rotating shaft 5 to deform, thereby affecting the normal operation of the entire rotating cold shear tail sweeping mechanism; on the other hand, the first rotating shaft 4 and the second rotating shaft 5 are installed on the guide plate bracket 13 to prevent the first rotating shaft 4 and the second rotating shaft 5 from damaging the guide plate body 11 during installation, thereby generating unnecessary friction on the steel in transportation, affecting the quality of the steel.

[0026] Furthermore, in some embodiments, the cold shear tail sweeping mechanism also includes an elastic buffer 6, which is installed between the guide plate body 11 and the guide plate bracket 13 to avoid direct contact between the guide plate body 11 and the guide plate bracket 13. The elastic buffer 6 plays a buffering role between the two. Since the guide plate body 11 will be subjected to a certain pressure when transporting steel and head and tail materials, an elastic buffer 6 is set between the guide plate body 11 and the guide plate bracket 13 to provide some buffer space for the guide plate body 11 when transporting steel and head and tail materials, thereby avoiding the guide plate body 11 or the guide plate bracket 13 from being subjected to force and causing loss when the weight of the steel or head and tail materials is large, thereby reducing maintenance costs.

[0027] It can be understood that the elastic buffer 6 is a disc spring or other parts with elastic and impact resistance to absorb and relieve the pressure of the guide body 11 and the guide bracket 13 on the steel or head and tail materials, and reduce the vibration between the guide body 11 and the guide bracket 13 during transportation.

[0028] In some embodiments, the tail sweeping guide plate 1 also includes a fixed column 14 installed between the guide plate body 11 and the guide plate bracket 13, wherein the fixed column 14 can be arranged perpendicular to the guide plate body 11, and the elastic buffer 6 is mounted on the fixed column 14, further ensuring that when transporting steel or head and tail materials, the elastic buffer 6 will not be separated from the guide plate body 11 and the guide plate bracket 13 due to the vibration between the guide plate body 11 and the guide plate bracket 13, thereby affecting the stability of the tail sweeping guide plate 1.

[0029] It can be understood that in order to ensure the rigidity of the overall structure of the tail sweeping guide plate 1, in some embodiments, the guide plate body 11, the connecting plate 12 and the guide plate bracket 13 are welded together. On the one hand, this prevents the entire tail sweeping guide plate 1 from being crushed by the excessive weight of the steel during transportation; on the other hand, when connecting the guide plate body 11, the connecting plate 12 and the guide plate bracket 13, the welding connection reduces the overall mass of the tail sweeping guide plate 1 compared to other connection methods, and greatly speeds up production efficiency.

[0030] Furthermore, since both the steel and the head and tail materials are transported on the guide plate body 11, in order to avoid the friction of the head and tail materials damaging the guide plate body 11, and the guide plate body 11 blocking the steel when transporting the steel, in some embodiments, the surface of the guide plate body 11 is provided with a wear-resistant coating. When the steel and the head and tail materials are transported on the guide plate body 11, they are always in contact with the wear-resistant coating, which increases the service life of the guide plate body 11 and further ensures the quality of the transported steel.

[0031] It is understood that the guide plate body 11 itself can be made of a more wear-resistant material, further ensuring that when the steel, head and tail materials come into contact with the guide plate body 11, the more wear-resistant guide plate body 11 is always in contact. This avoids unnecessary damage to the steel due to the failure to replace the wear-resistant coating on the guide plate body 11 in a timely manner when transporting steel or head and tail materials, thereby affecting the quality of the transported steel.

[0032] In some embodiments, the rotation angle of the tail sweeping guide plate 1 around the first rotation axis 4 is less than 90 degrees, that is, when the hydraulic cylinder 2 is extended and stable, the rotation angle of the tail sweeping guide plate 1 is 0 degrees at this time. When the hydraulic cylinder 2 contracts and drives the tail sweeping guide plate 1 to rotate, the rotation angle of the tail sweeping guide plate 1 around the first rotation axis 4 can be specifically 10 degrees, 20 degrees, 30 degrees, 45 degrees, 50 degrees, 60 degrees, 75 degrees, 80 degrees, 89 degrees, etc., to ensure that the tail sweeping guide plate 1 will not over-rotate due to excessive rotation angle when rotating, resulting in the tail sweeping guide plate 1 being unable to return to the state of 0 degree rotation angle under the drive of the hydraulic cylinder 2, affecting the subsequent work of the cold shear tail sweeping mechanism.

[0033] It can be understood that in some embodiments, the cold shear sweeping mechanism also includes a limiter (not shown), which is installed on the second rotating shaft 5 and is used to limit the relative rotation between the sweeping guide plate 1 and the support 3, and further limit the rotation angle of the sweeping guide plate 1, to prevent the sweeping guide plate 1 from rotating too much and being unable to rotate, affecting the normal operation of the entire cold shear sweeping mechanism.

[0034] Furthermore, in some embodiments, the cold shearing tail sweeping mechanism also includes a base 7, which is installed on the ground or on the cold shearing mechanism. The end of the hydraulic cylinder 2 away from the tail sweeping guide plate 1 is rotatably connected to the base 7, further enhancing the stability of the hydraulic cylinder 2 when driving the tail sweeping guide plate 1 to rotate, and ensuring the flexibility of the rotation of the tail sweeping guide plate 1.

[0035] In some embodiments, the cold shearing tail sweeping mechanism also includes a collecting device (not shown), the opening of which faces the tail sweeping guide plate 1, and when the tail sweeping guide plate 1 rotates, the projection of one end of the tail sweeping guide plate 1 falls within the range of the collecting device, that is, when the tail sweeping guide plate 1 rotates, the head and tail materials located on the tail sweeping guide plate 1 can always fall into the collecting device after rotation, ensuring that the cold shearing tail sweeping mechanism properly handles the head and tail materials.

[0036] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
