Description

Technical Field

[0001] The utility model relates to the technical field of metallurgical equipment, in particular to a hydraulic coil unloading machine used in metallurgy. Background Art

[0002] At present, the existing metal strip needs to be unloaded through a coiling device after being coiled by a coiler. The commonly used method is to transport the lifting device through a rail trolley, adjust the reel removal device to a suitable height through the lifting device, and then unload the metal strip after removing the reel, and the unloading efficiency is low.

[0003] There are many existing technologies for unwinding machines, such as:

[0004] Chinese patent publication number CN215089873U discloses a reel-type winder unloading device, which includes a rail trolley, which is arranged on a rail, and a first hydraulic lifting column is arranged on the upper end of the rail trolley, a fixed plate is arranged above the first hydraulic lifting column, a winding box is arranged at one end of the upper surface of the fixed plate, and one side of the winding box is opened with an opening, a fixed block is arranged at the other end of the upper surface of the fixed plate, a slidable slider is arranged between the fixed block and the winding box, a hydraulic telescopic rod is arranged between the fixed block and the slider, a second hydraulic lifting column is arranged on the upper surface of the slider, and an adjustment box is arranged at the upper end of the second hydraulic lifting column, and one side of the adjustment box is opened with an opening. The reel-type winder unloading device can effectively improve the unloading efficiency without removing the reel, greatly shortening the unloading time and greatly improving the convenience of use.

[0005] It can be seen from this that most of the rolled metal strips are unloaded by rail trolleys, which increases the production cost of the hydraulic unloading machine. If the reel is tightly connected to the inner wall of the rolled metal strip, the stability of the rolled metal strip can be increased, but the friction between the outer wall of the reel and the inner wall of the rolled metal strip will increase, increasing the work efficiency of unloading the rolled metal strip. If the rolled metal strip can be quickly unloaded by a hook block, the reel and the inner wall of the rolled metal strip may be unstable, reducing the quality of the metal strip winding, thereby reducing the practicality of the hydraulic unloading machine.

[0006] In view of this, we propose a hydraulic coil unloading machine for metallurgy. Utility Model Content

[0007] The utility model aims to solve the above-mentioned shortcomings and provide a hydraulic unloading machine for unloading a rolled metal plate strip by pushing a component.

[0008] The position of the paper ring of the rolled metal strip is fixed by the auxiliary component and the clamping component, thereby increasing the stability of the rolled metal strip. Similarly, the auxiliary component and the clamping component are used to reset the paper ring and the pushing component is used to unload the rolled metal strip.

[0009] Therefore, the utility model provides a hydraulic coil unloading machine for metallurgy, which comprises two connecting rods, and the two ends of the two connecting rods are respectively provided with a body and a storage box for storing coiled metal strips, and a reel is arranged above the body near one side of the connecting rod.

[0010] An auxiliary component is arranged inside the reel, and two clamping components for stabilizing the position of the paper ring of the wound metal sheet are arranged on the outside of the auxiliary component. The auxiliary component is used to adjust the distance between the two clamping components and limit the position of the paper ring of the wound metal sheet. A pushing component for assisting in unloading the rolled metal sheet is arranged on the side of the machine body close to the reel.

[0011] As a further improvement of the technical solution, the pushing assembly comprises at least a multi-stage hydraulic cylinder, the multi-stage hydraulic cylinder is arranged inside the machine body on the side close to the reel, and the piston rod of the multi-stage hydraulic cylinder is provided with a push ring.

[0012] As a further improvement of the present technical solution, the auxiliary component at least includes a cavity, a cavity is opened inside the reel, a motor is arranged inside the cavity, the output shaft of the motor extends to the inside of the reel and is coaxially connected to a bidirectional screw rod, and moving blocks are threadedly connected to both ends of the outer wall of the bidirectional screw rod.

[0013] As a further improvement of the technical solution, the clamping assembly at least includes a multi-stage cylinder, the four sides of the moving block are provided with multi-stage cylinders, and the piston rods of the multi-stage cylinders are provided with L-shaped clamping plates.

[0014] As a further improvement of the technical solution, an anti-slip layer is provided on the side of the L-shaped clamping plate away from the multi-stage cylinder.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] In the hydraulic unloading machine used in metallurgy, the position of the paper ring of the metal plate strip is fixed by the auxiliary component and the clamping component, which increases the stability of the metal plate strip winding, not only increases the quality of the metal plate strip winding, but also improves the working efficiency of the metal plate strip winding, avoids the waste of time, and improves the flexibility of the use of the hydraulic unloading machine. Similarly, the work of resetting the auxiliary component and the clamping component and using the pushing component to unload the rolled metal plate strip is beneficial to improving the convenience of the use of the hydraulic unloading machine. There is no need to remove the reel, which greatly shortens the unloading time, thereby improving the practicality of the hydraulic unloading machine. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Most of the rolled metal strips are unloaded by rail trolleys, which increases the production cost of the hydraulic unloading machine. If the reel is tightly connected to the inner wall of the rolled metal strip, the stability of the rolled metal strip can be increased, but the friction between the outer wall of the reel and the inner wall of the rolled metal strip will increase, which will increase the work efficiency of unloading the rolled metal strip. If the rolled metal strip can be quickly unloaded by a hook block, the reel and the inner wall of the rolled metal strip may be unstable, which reduces the quality of the metal strip winding and thus reduces the practicality of the hydraulic unloading machine.

[0026] See also Figure 1-Figure 4 The embodiment of the utility model shown in the figure comprises two connecting rods 10, at both ends of the two connecting rods 10 are respectively provided with a body 11 and a storage box 12 for storing rolled metal sheets and strips, a reel 20 is provided above the body 11 close to the connecting rod 10, an auxiliary component 21 is provided inside the reel 20, two clamping components 22 for stabilizing the position of the paper ring of the rolled metal sheet and strip are provided on the outer side of the auxiliary component 21, the auxiliary component 21 is used to adjust the distance between the two clamping components 22 and limit the position of the paper ring of the rolled metal sheet and strip, and a pushing component 13 for assisting in unloading the rolled metal sheet and strip is provided on the side of the body 11 close to the reel 20.

[0027] First, the specific structure of the pushing assembly 13 is disclosed. The pushing assembly 13 at least includes a multi-stage hydraulic cylinder 131. The multi-stage hydraulic cylinder 131 is arranged inside the body 11 on the side close to the reel 20. The piston rod of the multi-stage hydraulic cylinder 131 is provided with a push ring 132.

[0028] The improvement lies in that after the metal sheet strip is wound up, the multi-stage hydraulic cylinder 131 is connected to the power supply to make it work. Through the pushing work of the piston rod of the multi-stage hydraulic cylinder 131, the push ring 132 is pushed toward the storage box 12, and the rolled metal sheet strip on the reel 20 is pushed out of the outer wall of the reel 20 so that it enters the interior of the storage box 12, thereby improving the unloading efficiency of the hydraulic unloading machine. There is no need to unload the reel 20, which greatly shortens the unloading time and improves the convenience of using the hydraulic unloading machine, thereby improving the practicality of the hydraulic unloading machine.

[0029] Secondly, the specific structure of the auxiliary component 21 is disclosed. The auxiliary component 21 at least includes a cavity 211. The interior of the reel 20 is provided with a cavity 211. The interior of the cavity 211 is provided with a motor 212. The output shaft of the motor 212 extends to the interior of the reel 20 and is coaxially connected to a bidirectional screw rod 213. Both ends of the outer wall of the bidirectional screw rod 213 are threadedly connected to a moving block 214.

[0030] The improvement lies in: connecting the motor 212 to the power supply to make it work, and the output shaft of the motor 212 rotates clockwise, driving the bidirectional screw rod 213 to rotate clockwise, so that the two moving blocks 214 are close to each other. Similarly, the output shaft of the motor 212 rotates counterclockwise to move the two moving blocks 214 away from each other, which is conducive to the winding of metal plates and strips of different sizes, reduces the production cost of the hydraulic unwinding machine, improves the flexibility of the use of the hydraulic unwinding machine, and thus improves the practicality of the hydraulic unwinding machine.

[0031] The specific structure of the clamping assembly 22 is disclosed again. The clamping assembly 22 at least includes a multi-stage cylinder 221 . The four sides of the moving block 214 are provided with the multi-stage cylinder 221 . The piston rod of the multi-stage cylinder 221 is provided with an L-shaped clamping plate 222 .

[0032] The improvement lies in: putting the paper ring of the wound metal strip on the surface of the reel 20, and then connecting the power supply to the multi-stage cylinder 221 to make it work. The L-shaped clamping plate 222 is moved out of the interior of the reel 20 through the pushing of the piston rod of the multi-stage cylinder 221, and the position of the paper ring of the wound metal strip is fixed, which also plays a role of limiting the winding of the metal strip, thereby increasing the quality of the winding of the metal strip, and improving the working efficiency of the winding of the metal strip, thereby improving the flexibility of the use of the hydraulic unwinding machine.

[0033] Taking into account that the side of the L-shaped clamping plate 222 away from the multi-stage cylinder 221 is tightly attached to the inner wall of the rolled metal strip, when the metal strip is rolled up, the inner wall of the rolled metal strip and one side of the L-shaped clamping plate 222 may slip, affecting the working efficiency of the metal strip and reducing the practicality of the hydraulic unloading machine. Therefore, an anti-slip layer 23 is provided on the side of the L-shaped clamping plate 222 away from the multi-stage cylinder 221.

[0034] The improvement lies in that: by providing an anti-slip layer 23, the friction between the L-shaped clamping plate 222 and the inner wall of the rolled metal sheet can be increased, thereby increasing the stability of the position of the rolled metal sheet. This not only improves the work efficiency of metal sheet winding and avoids wasting time, but also improves the quality of metal sheet winding, thereby improving the practicability of the hydraulic unwinding machine.

[0035] In summary, the working principle of this scheme is as follows: first, the paper ring of the wound metal strip is sleeved on the surface of the reel 20, and then the motor 212 is powered on to make it work, and the output shaft of the motor 212 rotates clockwise, driving the bidirectional screw rod 213 to rotate clockwise, so that the two moving blocks 214 are close to each other, and at the same time, the multi-stage cylinder 221 is powered on to make it work, and the piston rod of the multi-stage cylinder 221 pushes the L-shaped clamping plate 222 out of the interior of the reel 20, and the position of the paper ring of the wound metal strip is fixed, so that the preparation work of winding the metal strip is completed;

[0036] When it is necessary to unload the rolled metal sheet, first, the L-shaped clamping plate 222 is retracted into the interior of the reel 20 through the work of resetting the piston rod of the multi-stage cylinder 221. At the same time, the output shaft of the motor 212 is rotated counterclockwise to move the two moving blocks 214 away from each other. After that, the multi-stage hydraulic cylinder 131 is powered on to make it work. The push ring 132 is pushed toward the storage box 12 through the work of the piston rod of the multi-stage hydraulic cylinder 131, and the rolled metal sheet on the reel 20 is pushed out of the outer wall of the reel 20 and into the interior of the storage box 12, thereby completing the work of unloading the metal sheet.
