Description

Technical Field

[0001] The utility model relates to the technical field of steel rolling production, in particular to an intelligent integrated finishing rolling pressure adjustment device. Background Art

[0002] Adjusting the finishing rolling K1 and K2 press-down devices is the main means of adjusting negative tolerances in daily production. With the improvement of production technology, negative tolerance indicators have become particularly important, and the frequency of adjusting the K1 and K2 press-down devices has become increasingly higher. Due to the constraints of the safety system, when adjusting the press-down operation, the rolling rhythm must be pulled apart, and the relevant rotating parts have not been enlarged and lengthened. The entire adjustment process cannot be accurately quantified and is inconvenient to adjust, which will lead to abnormal fluctuations in the production rolling process and even steel piling, which will lead to interruptions in the production process. This seriously restricts the increase in one-bar-hour output. The reduction in output will lead to an increase in the production cost per ton of steel and an increase in the consumption of energy media per ton of steel, which will reduce production efficiency.

[0023] See also Figure 1 , an intelligent integrated finishing rolling pressure adjustment device, used for pressure adjustment of rolling mill rolls during rolling process, the device comprises a three-dimensional square cover 1, an upper transmission roller 4, a lower transmission roller 5, a connecting rod 8, a steering lap joint 7, a rod end connector 15 and a power pressure rod 16. The upper transmission roller 4 and the lower transmission roller 5 are arranged in the three-dimensional square cover 1 in an upper and lower relative manner, and the upper transmission roller 4 and the lower transmission roller 5 are used as rolling rollers, and the upper and lower parts cooperate to extrude and deform the rolled piece. The connecting rod 8 is arranged horizontally, one end of which is connected to the end of the upper transmission roller 4 through the steering lap joint 7, and the end of the connecting rod 8 away from the steering lap joint 7 is connected to the power pressure rod 16 through the rod end connector 15.

[0024] The three-dimensional square cover 1 provides all-round protection for the upper transmission roller 4 and the lower transmission roller 5 to prevent the upper transmission roller 4 and the lower transmission roller 5 from being subjected to abnormal collisions during normal production and rolling. The steering lap joint 7 is an intelligent steering connection interface, which realizes intelligent and smooth connection of pressure conduction, making it more intelligent. The connecting rod 8 serves as the direct bearing of the rotation output of the upper transmission roller 4 and the lower transmission roller 5 and the lateral bearing body of kinetic energy conduction. Through an integrated rotation connection, the rotation conduction across space is realized.

[0025] In this embodiment, the rod end connector 15 is fixedly sleeved on the outer peripheral surface of the end of the connecting rod 8. The connecting rod 8 is rotated by the power pressure rod 16, and the connecting rod 8 is linked with the steering lap 7 and the upper transmission roller 4 to realize the downward pressing of the lower transmission roller 5. The end of the power pressure rod 16 away from the rod end connector 15 is connected with a ring 17, which can provide a convenient point of force for the downward adjustment of the production rolling personnel, and at the same time provide multi-dimensional standing safety protection for the personnel.

[0026] The first drive connector 2 is connected to one end of the upper transmission roller 4 relative to the steering lap 7, and the second drive connector 3 is connected to the end of the lower transmission roller 5. In this embodiment, the first drive connector 2 and the second drive connector 3 are both connected to the motor to realize the drive transmission of the motor kinetic energy and mechanical buffer deceleration, so as to transfer the kinetic energy to the ends of the upper transmission roller 4 and the lower transmission roller 5, so that the upper transmission roller 4 and the lower transmission roller 5 rotate and squeeze the rolled piece, thereby realizing the rolling process.

[0027] See also Figure 1 A first connecting flange 9 is provided at the connection between the connecting rod 8 and the steering lap member 7, and a first rod length adjusting member 10 is installed on the first connecting flange 9. Through the first connecting flange 9, the connecting rod 8 and the steering lap member 7 are combined into an integrated structure, thereby realizing an integrated integrated output. Through the first rod length adjusting member 10, the intelligent adjustment of the length of the connecting rod 8 and the combined enhancement of the strength of the fixed end are realized.

[0028] A second connecting flange 13 is provided at the connection between the connecting rod 8 and the protective fence 11, and a second rod length adjusting member 14 is installed on the second connecting flange 13. The second connecting flange 13 has the same structure and function as the first connecting flange 9, and the second rod length adjusting member 14 has the same structure and function as the first rod length adjusting member 10, which will not be described in detail here.

[0029] In this embodiment, the stress-bearing points at both ends of the connecting rod 8 and the components connected to the connecting rod 8 are enlarged and lengthened. The connecting rod 8 cooperates with the steering lap joint 7, the first connecting flange 9 and the first rod length adjustment member 10 to achieve precise adjustment of the downward adjustment operation, which not only ensures the stability of the production rolling process, but also improves production efficiency.

[0030] See also Figure 1 A protective fence 11 is provided on one side of the three-dimensional square cover 1, and the end of the connecting rod 8 away from the three-dimensional square cover 1 passes through the side of the protective fence 11 opposite to the three-dimensional square cover 1. The protective fence 11 isolates the area near the rolling process, thereby avoiding the safety impact of steel piling during the rolling process, and providing a good safety environment for the relevant operations of the personnel on duty.

[0031] Among them, an observation window 12 is provided on the protective fence 11. In this embodiment, the observation window 12 is a frame-shaped window, and can also be other geometric shapes that are convenient for observation, such as circular, trapezoidal, etc., so that operators can diagnose through a local small area window to achieve efficient and safe detection of the rolling state and product quality state. The lower end side of the protective fence 11 is connected to a triangular support frame 18 for support. There are at least two triangular support frames 18, which are symmetrically arranged on one side of the protective fence 11, and can also be arranged on both sides of the protective fence 11. The triangular support frame 18 has a triangular stable structure, which can achieve strong and stable support for the protective fence 11.

[0032] Preferably, an inspection platform 6 is provided beside the three-dimensional square cover 1, and the inspection platform 6 is used for dynamic adjustment of rolling and dynamic visual inspection of the rolling state.

[0033] The pressure adjustment process of the intelligent integrated finishing rolling pressure adjustment device of the utility model is as follows: the staff holds the end of the power pressure rod 16 away from the connecting rod 8, and presses down or lifts up along the circumference of the connecting rod 8, so that the connecting rod 8 rotates circumferentially along its axis. When the connecting rod 8 rotates, it is linked with the upper transmission roller 4 through the steering lap joint 7, driving the upper transmission roller 4 to rise or fall, thereby realizing the roller pressure adjustment operation in the finishing rolling process. In the above process, the staff stands behind the protective fence 11 and does not contact the equipment in the rolling process, so it is safer, and the pressure adjustment operation can be realized by operating the power pressure rod 16, which is not only convenient for adjustment, but also does not need to open the rolling rhythm. On average, 40S of time can be saved in one hour, that is, the output is increased by 1 stick per hour, thereby improving production efficiency.
