Description

Technical Field

[0001] The utility model relates to the technical field of metallurgical hot rolling, in particular to a follow-up shearing machine. Background Art

[0002] In the production process of high-quality steel, the rolled pieces on the rolling line need to be cut into a certain length for the next rolling production.

[0003] At present, most hydraulic shears require the workpiece to stop on the rolling line during operation, and the hydraulic cylinder drives the shear blade to shear the workpiece. After the shearing is completed, the hydraulic cylinder drives the shear blade to retract and the workpiece continues to move forward. Due to the limitation of the shearing method, the workpiece must remain stopped during the operation of the hydraulic shear. Once the workpiece does not stop or moves during the shearing process, it will cause damage to the hydraulic shear equipment. In addition, since the workpiece needs to stop and wait for shearing, the production cycle is invisibly lengthened and the fast-paced production process is slowed down. In addition, since the workpiece must remain stopped during the operation of the hydraulic shear, steel piling accidents are inevitable during the production process. Once a steel piling accident occurs, the hydraulic shear cannot provide effective loss-stopping measures such as breaking.

[0004] During the production process, due to the different composition of the rolled pieces and different production processes, the temperature of the rolled pieces passing through the hydraulic shears ranges from 700℃ to 1200℃. As equipment that is in close contact with the rolled pieces, the various components on the hydraulic shears are exposed to high temperature environments for a long time, which poses severe challenges to lubrication, sealing, etc. The hydraulic cylinders, pipelines and other components of the existing hydraulic shears are not resistant to high temperatures. During the production process, due to the influence of high temperatures, there is often a lack of lubricating oil, resulting in structural wear and oil leakage due to poor sealing, which drips onto the rolled pieces and creates a fire hazard.

[0005] In view of this, the inventor has designed a follow-up shearing machine based on many years of production design experience in this field and related fields and after repeated experiments, in order to solve the problems existing in the prior art. Utility Model Content

[0065] Furthermore, the guide device 80 may adopt the existing technology, which will not be described in detail here.

[0066] Please refer to Figures 1 to 4 Now, the specific implementation process of the follow-up shearing machine 100 proposed by the utility model is described in detail in conjunction with an embodiment.

[0067] In this embodiment, the follow-up shearing machine 100 is composed of a driving device 30 (hydraulic cylinder), two tool holders 20 located at the upper and lower parts, a connecting rod 41, a frame 10, a detection element 70, a cooling device 60, a guide device 80 and other supporting components. The hydraulic cylinder is suspended on the frame 10 through an ear shaft and a sleeve end cover. The cylinder head 31 of the hydraulic cylinder is connected to the upper tool holder 20 through a shaft and a sleeve. The upper tool holder 20 rotates around the central axis 11. A sleeve and a spacer ring are arranged between the tool holder 20 and the central axis 11. When the upper tool holder 20 moves, the connecting rod 41 is driven to move through the central axis 11. A connecting rod 43 is arranged between the two connecting rods 41 to ensure that the distance between the two connecting rods 41 is a fixed value. The upper end of the connecting rod 41 is hinged to the upper tool holder 20 through a pin 42, and the lower end of the connecting rod 41 is hinged to the lower tool holder 20 through a pin 42. The lower tool holder 20 moves around the central axis 11. When the follow-up shearing machine 100 is running, the hydraulic cylinder is the power source to push the upper and lower knife racks 20 from Figure 1 Initial position to Figure 2 Closed position.

[0068] After the hydraulic cylinder is installed, the reinforcement plate 13 is fixed to the frame 10 by bolts to enhance the strength of the machine body. The shear blade 50 is fixed to the upper tool holder 20 and the lower tool holder 20 by a wedge bolt and a gasket set. In order to prevent the wedge bolt from breaking and causing difficulty in replacing the shear blade, the bolt holes for fixing the shear blade 50 and the wedge bolt are through holes for easy disassembly and installation. The swing amplitude of the hydraulic cylinder does not exceed 1° during operation, ensuring that the thrust of the hydraulic cylinder is basically fully utilized. Figure 1 , Figure 2 , the upper tool holder 20 is symmetrical with the two limit positions and the maximum arm line of the hydraulic cylinder to ensure that the output force is always near the maximum value during the working process. After the shear blade 50 and the tool holder 20 are installed, the cooling device 60 is fixed to the frame 10 by bolts. The two parts of the detection element 70 are fixed to the tool holder 20 and the frame 10 respectively. Only when the set signal is detected, the follow-up shearing machine 100 will proceed to the next working state, thereby ensuring production safety.

[0069] like Figure 1 , Figure 2 As shown, when the rolled piece needs to be trimmed, the hydraulic circuit controls the hydraulic cylinder to match the speed of the rolled piece and perform trimming. After trimming, the rolled piece moves backward (to facilitate the opening of the two shear blades 50). The two shear blades 50 are Figure 2 Position back Figure 1 Position, the waste material at the head of the rolled piece falls into the collection basket under the platform, and the rolled piece moves forward. The guide device 80 prevents the head of the rolled piece from being too high and hitting the shear blade 50 above. When the rolled piece needs to be trimmed, the rolled piece does not need to change in speed. The tool holder 20 and the shear blade 50 directly match the speed of the rolled piece to perform the trimming work, and the waste material falls into the collection basket. A cooling device 60 is set on the incoming side of the follow-up shearing machine 100. When the rolled piece is incoming, the cooling water enters the sealed space inside through the lower part of the cooling device 60 for heat exchange. After absorbing the heat from the rolled piece, it is discharged from the upper part, reducing the temperature of the working area of ​​the hydraulic cylinder behind the cooling device 60, effectively alleviating the harm caused by high temperature.

[0070] The follow-up shearing machine 100 proposed in the utility model can realize follow-up shearing during the period without accidents to speed up the production speed; when an accident occurs, it can also perform cutting shearing to ensure production safety, realize multiple uses of one machine, reduce costs and increase efficiency, and at the same time ensure production safety, it can also play a role in improving the quality of rolled products.

[0071] The follow-up shearing machine 100 proposed in the utility model is provided with a cooling device 60, which effectively reduces the temperature around the equipment, especially the temperature near the hydraulic cylinder. The follow-up shearing machine 100 provides a good working environment for the machine body and internal components, and reduces maintenance costs and leakage risks.
