Description

TECHNICAL FIELD

[0001] The utility model relates to metallurgical rolling equipment technical field, concretely relates to a kind of head, tail automatic tracking device for high-speed wire rod flying shear cutting, for real-time monitoring whether the scrap after shearing is normally dropped, avoid steel stacking failure. BACKGROUND

[0002] In the key production link of high-speed wire rod rolling, after red steel is rolled, its head and tail part can generate defects such as size deviation, surface crack, internal organization unevenness in the rolling process, in order to ensure the quality of subsequent products, it needs to be accurately sheared by flying shear to remove these defective parts.

[0003] However, in actual production process, due to improper adjustment of blade gap, strip tension fluctuation, shearing temperature change and other multiple factors, flying shear often fails to drop in time when cutting head or tail. This problem is hidden, as the operator cannot realize in real time that the head or tail does not drop in the main control room, and cannot take timely measures, so the head or tail that does not drop will be brought into the subsequent rolling channel. In the rolling channel, the entry of foreign matter will seriously interfere with the normal rolling process, eventually leading to the generation of steel stacking and scrap cutting failure, causing production stagnation, raw material waste and product quality damage and a series of adverse consequences. In the face of this problem, the operator has to frequently leave the main control room and go to the site for inspection and treatment. This process greatly reduces production efficiency and increases labor intensity.

[0004] Currently, the existing technical means has obvious deficiencies in scrap treatment, especially lacking an effective automatic detection and alarm mechanism for the dropping state of head and tail. This leads to the fact that the operator cannot know the dropping state of scrap in time and cannot discover and solve abnormal problems such as jamming in the first time. Therefore, it is urgent to develop a device that can feedback the dropping state of scrap in real time and accurately, which is of great significance to improve the production efficiency of high-speed wire rod rolling and improve product quality.

[0013] Compared with the prior art, the device has the following beneficial effects:

[0014] 1. The waste falling state is monitored in real time through the linkage of the proximity switch and the signal lamp, and the manual inspection frequency is reduced.

[0021] As shown in Figure 1 and 2 A flying shear head tail tracking device, a rotating baffle 1 is arranged on the falling path of the head and tail cut off by the flying shear, the rotating baffle 1 is fixedly connected with one end of a connecting rod 2, a block 3 is fixedly arranged on the other end of the connecting rod 2, the connecting rod 2 is rotatably connected with a bearing 6, the bearing 6 is arranged on the front and back of the block 3, a proximity switch 4 is arranged on the movement path of the block 3, the proximity switch 4 and the bearing 6 are both fixed on a support frame 5, the bearing 6 ensures that the block 3 can respond to the rotation of the rotating baffle 1 sensitively and smoothly, avoids signal delay or failure caused by excessive friction, makes the rotation of the block 3 more stable, avoids jamming or shaking, and the bearing 6 is a standard part, easy to replace and maintain. The support frame 5 is fixed on a base 7, one end of the base 7 away from the rotating baffle 1 is connected with a cylinder 9, for adjusting the position of the base 7; the proximity switch 4 is electrically connected with a signal lamp to generate a detection signal, the signal lamp is arranged in a main control room, and the proximity switch 4 is also electrically connected with a rolling control system, and the opening and closing of the rolling control system controls the operation and stop of the flying shear and the red steel on the production line.

[0022] Further, the rotating baffle 1 is composed of three blades distributed at equal angles, and the material of the rotating baffle 1 is high-temperature-resistant metal alloy.

[0023] Further, the device further comprises an electric induction angle sensor 8, the electric induction angle sensor 8 is installed on the rotating shaft of the connecting rod 2, the electric induction angle sensor 8 is also electrically connected with the signal lamp and the rolling control system, for detecting the rotation angle of the rotating baffle 1 and generating an auxiliary signal, and the auxiliary signal and the detection signal of the proximity switch 4 form double verification, the auxiliary signal and the detection signal are transmitted to the main control room together, to ensure the detection reliability; at the same time, the auxiliary signal can be used for fault diagnosis, data recording and system linkage, to further improve the intelligent level of the device.

[0024] Further, the working pressure of the cylinder 9 is 0.4 MPa, and is fixed on the cylinder base 10, and its stroke range covers the adjustment requirement of different positions below the flying shear.

[0025] Further, the proximity switch 4 is an inductive proximity switch, and the sensing distance thereof is adjustable to adapt to the detection requirement of different sizes of cut head and tail.

[0026] The device has two working states: when the cut head and tail normally drop to trigger the rotation of the rotating baffle 1 to drive the rotation of the connecting rod 2, then drive the movement of the stop block 3 and trigger the proximity switch 4, the signal light remains off; when the cut head and tail do not normally drop, the rotating baffle 1 does not rotate, and the proximity switch 4 is not triggered, the signal light flashes to alarm and closes the rolling control system to prohibit steel tapping.

[0027] The working process of the device is as follows: the rotating baffle 1 is installed on the drop path of the cut head and tail below the flying shear, the operator operates the rolling control system in the main control room to make the flying shear cut the head and tail of the red steel, in the normal working state, the flying shear performs the cutting operation, and when the cut head and tail normally drop, the rotating baffle 1 is impacted. The rotating baffle 1 is forced to drive the connecting rod 2 to rotate through the rotating shaft, and the stop block 3 on the connecting rod 2 moves to trigger the proximity switch 4. The proximity switch 4 (inductive proximity switch, sensing distance can be adjusted according to the size of the cut head and tail) transmits the detection signal to the signal light, and the inductive angle sensor 8 on the connecting rod 2 receives the change of the angle to transmit the auxiliary signal to the signal light, at this time, the signal light remains off, indicating that the cut head and tail normally drop, and the rolling control system normally operates to continuously tap the steel.

[0028] Abnormal working state: after the operator operates the rolling system in the main control room to cut the head and tail of the red steel, if the cut head does not normally drop, the rotating baffle 1 is not impacted before cutting the tail of the red steel, the stop block 3 does not move, and the proximity switch 4 is not triggered. At the same time, the inductive angle sensor 8 detects that the rotating baffle 1 has no rotation angle change, and the generated auxiliary signal also shows abnormality. The non-triggering signal of the proximity switch 4 and the abnormal auxiliary signal of the inductive angle sensor 8 are transmitted to the signal light together, the signal light starts to flash and alarm, and the rolling control system is closed in linkage to prohibit steel tapping, so as to avoid the fault of steel piling caused by the non-dropping of the cut head and tail. In this process, the cylinder 9 can adjust the position of the base 7 in its stroke range according to the actual requirement, so as to ensure that the device is always in the best detection state.
