Detailed Description
In order to better explain the technical scheme disclosed by the invention, the following specific description is combined with specific examples.
Example 1
The embodiment discloses a synchronous hydraulic shearing method for continuous casting billets, which is characterized in that a pressing synchronizer 2 positioned on a rack 1 is utilized to apply pressure to a billet 4, the billet 4 drives the rack 1 to do synchronous motion, and a shearing mechanism 3 on the rack 1 shears the billet 4 in the process that the billet 4 drives the rack 1 to do synchronous motion, as shown in figure 1. The pressing synchronization device 2 on the frame 1 is a shearing device 5 of the shearing mechanism 3 arranged on the frame 1, and the billet 1 is pressed by the shearing device 5. The shearing mechanism 3 shears the billet 4 by moving the lower shearing device 6 upward, and the upper shearing device 5 performs a shearing process while pressing the billet 4. Meanwhile, when the lower shearing device 6 moves upward to perform shearing, the upper shearing device 5 presses the billet 4 and resets at the same time. However, the resetting is only to generate a certain degree of displacement, and the process that the upper shearing device 5 compresses the steel billet 4 to drive the rack 1 to move is not influenced, and because the lower shearing device 6 is in contact with the steel billet 4 in the shearing process, friction force is inevitably generated, so that the lower shearing device 6 and the upper shearing device 5 apply vertical acting force to the steel billet 4 in the shearing process, and the rack movement is ensured.
As can be seen from fig. 1, the method proceeds to the process of pre-billet-shearing I → simultaneous compaction II → simultaneous following and shearing III → shearing completion IV → returning to the pre-shearing initial position V. When a steel billet 4 needs to be sheared, an upper shearing device 5 of a shearing mechanism 3 vertically moves downwards to be in contact with the steel billet 4 and applies pressure to the steel billet 4, the friction force between the steel billet 4 and the upper shearing device 5 brought by the pressure enables a pressing synchronization device 2 and the steel billet 4 to synchronously move together, and the pressing synchronization device 2 is connected to a rack 1, so that the rack 1 and the steel billet 4 synchronously move together; then the lower shearing device 6 of the shearing mechanism 3 vertically moves upwards to cut the steel billet 4, because the acting force of the upward movement of the lower shearing device 6 on the steel billet 4 is greater than the downward pressing force of the upper shearing device 5 on the steel billet 4, the upper shearing device 5 needs to be reset upwards, but the resetting does not influence the process that the upper shearing device 5 presses the steel billet 4 to drive the rack 1 to do synchronous movement, and meanwhile, the lower shearing device 6 always moves vertically upwards until the steel billet cutting at the position is finished; after the cutting is finished, the lower shearing device 6 returns to the initial position under the action of external force, the upper shearing device 5 loses the compaction on the steel billet, the whole rack 1 returns to the initial position under the action of external force, and the next shearing signal is continuously waited until the cutting in the whole stage is finished.
The embodiment discloses that in the process of shearing the steel billet, the movement of the steel billet drives the rack to synchronously move together, so that the complete consistency of the displacement of the rack and the displacement of the steel billet can be ensured, the effect of protecting a sealing ring and a blade of a shearing hydraulic cylinder in the shearing process is realized, and the service life of equipment is prolonged; and the steel billet can be ensured to run stably (the liquid level of the molten steel of the crystallizer is not fluctuated, and the steel billet is not pulled by a blade), so that the internal quality of the steel billet is good and the appearance shape of the shearing section is regular and regular.
