Description

Technical Field

[0002] In the production process of steel billets, there is a water cooling step. The spraying section is set on the conveyor rollers, and the surface of the steel billet is sprayed as it passes by to cool it down. Currently, the width of the water curtain sprayed by the spraying section is fixed and cannot be adjusted. However, the width of the water curtain varies from batch to batch of steel billets.

[0015] See Figure 1 and Figure 2This utility model includes a front sensing element, a rear sensing element, and a cooling section. The front and rear sensing elements are both disposed on one side of the billet conveying roller conveyor 1. The cooling section is disposed on both sides of the billet conveying roller conveyor 1, and is located between the front and rear sensing elements. The billet passes through the front sensing element, the cooling section, and the rear sensing element in sequence. The front sensing element can sense the arrival of the billet, and the rear sensing element can sense the departure of the billet. The on / off state of the cooling water spray is controlled by the cooperation of the front and rear sensing elements. The cooling section is used to perform water spray cooling treatment on the billet.

[0016] The cooling section includes a first side positioning mechanism, a second side positioning mechanism, an arc-shaped guide mechanism, a spraying mechanism, and a follow-up mechanism. The first side positioning mechanism and the second side positioning mechanism are respectively located on both sides of the billet conveying roller table 1. The first side positioning mechanism and the second side positioning mechanism are used to clamp the two sides of the width of the billet, thereby allowing the spraying mechanism above to adapt to the positioning mechanism, ensuring that the two ends of the spraying mechanism are aligned with the two sides of the billet, ensuring that the sprayed water curtain is not wasted, and spraying as much water as possible onto the billet. The arc-shaped guide mechanism is located on the first side positioning mechanism, the follow-up mechanism is located on the second side positioning mechanism, and the spraying mechanism is located between the arc-shaped guide mechanism and the follow-up mechanism. The arc-shaped guide mechanism and the follow-up mechanism work together to allow the spraying mechanism to adapt to the position adjustment of the first side positioning mechanism and the second side positioning mechanism.

[0017] The first side positioning mechanism includes a first column 2, a first guide rod 3, a first spring 4, a first vertical plate 5, and a first triangular top block 6. The first column 2 is disposed on one side of the billet conveying roller conveyor 1. A guide hole is provided on the first column 2, and the first guide rod 3 passes through the guide hole. The center line of the first guide rod 3 is parallel to the width direction of the conveying roller conveyor 1. The end of the first guide rod 3 near the conveying roller conveyor 1 is connected to the bottom end of the side wall of the first vertical plate 5. The first spring 4 is disposed between the first vertical plate 5 and the first column 2. The first spring 4 provides the first vertical plate 5 with a forward force, which is the first... The triangular top block 6 provides the force to press against the side wall of the billet; the first guide rod 3 provides guidance for the back-and-forth movement of the first vertical plate 5; the first triangular top block 6 is located at the bottom end of the end face of the first vertical plate 5 near the conveyor roller 1, and the end of the first triangular top block 6 away from the first vertical plate 5 is an arc-shaped end; when the billet passes by, it pushes away the triangular hypotenuse of the first triangular top block 6, causing the first vertical plate 5 to retract, and the arc-shaped end of the first triangular top block 6 smoothly presses against the side wall of the billet, which also ensures that the end of the water pipe 18 above it is located directly above the side of the billet, avoiding the spraying of cooling water onto the position where there is no billet.

[0018] The second side positioning mechanism operates on the same principle as the first side positioning mechanism, with both positioning contacts at both ends of the steel billet, ensuring that the other end of the water pipe is directly above the other side of the steel billet. The second side positioning mechanism includes a second column 7, a second guide rod 8, a second spring 9, a second vertical plate 10, and a second triangular top block 11. The second column 7 is positioned on one side of the steel billet conveying roller conveyor 1, while the first column 2 and the second column 7 are positioned on opposite sides of the conveying roller conveyor 1. The second column 7 has a guide hole, through which the second guide rod 8 passes, with its centerline parallel to the width direction of the conveying roller conveyor 1. The end of the second guide rod 8 near the conveying roller conveyor 1 is connected to the bottom end of the side wall of the second vertical plate 10. The second spring 9 is positioned between the second vertical plate 10 and the second column 7. The second triangular top block 11 is positioned at the bottom end of the end face of the second vertical plate 10 near the conveying roller conveyor 1, with the end of the second triangular top block 11 away from the second vertical plate 10 being an arc-shaped end.

[0019] The arc-shaped guide mechanism includes a horizontal support plate 12, a disc 13, and an arc-shaped guide strip 14; the horizontal support plate 12 is located at the top end of the first vertical plate 5 near the conveyor roller 1; the disc 13 is located on the bottom end surface of the horizontal support plate 12; the side wall of the arc-shaped guide strip 14 is connected to the circumferential side wall of the disc 13 through a bracket; the axis of the arc-shaped guide strip 14 coincides with the axis of the disc 13.

[0020] The follower mechanism includes a horizontal rod 15 and a slider 16; the horizontal rod 15 is located at the top end of the second vertical plate 10 near the conveyor roller 1; a slide rail is provided along the length of the end face of the horizontal rod 15 near the conveyor roller 1, and the slider 16 is slidably mounted on the slide rail of the horizontal rod 15 through a groove thereon, and limit blocks are provided at both ends of the slide rail; the end of the slider 16 is connected to the outer wall of the outer ring of the first bearing, and the inner wall of the inner ring of the first bearing is connected to the side wall of the round rod.

[0021] When the distance between the two vertical plates changes, the assembly of the horizontal long plate 17 and the water pipe 18 needs to be adjusted to adapt the angle. The spraying mechanism includes the horizontal long plate 17 and the water pipe 18. The water pipe 18 is located on the bottom end face of the horizontal long plate 17, and a connector is provided at the end of the water pipe 18. The connector is connected to a high-pressure water source through a long flexible hose. A solenoid valve is provided on the long flexible hose, and the signal input end of the solenoid valve is connected to the signal output end of the CPU. Multiple nozzles are evenly arranged along the length of the bottom end face of the side wall of the water pipe 18, and the nozzles are connected to the inner cavity of the water pipe 18. The bottom end of the round rod is connected to one end of the top surface of the horizontal long plate 17. An annular guide groove is provided at the end of the top surface of the horizontal long plate 17 away from the round rod. The annular guide strip on the bottom surface of the disc 13 is slidably disposed within the annular guide groove of the horizontal long plate 17. One end of the horizontal long plate 17 can rotate around the disc 13, while the other end of the horizontal long plate moves adaptively through the rotation of the round rod and the sliding of the slider 16, ensuring that the horizontal long plate is reliably positioned between the two vertical plates, and the distance between the two vertical plates and the two side walls of the steel billet remains constant. This further ensures that both ends of the water pipe are reliably positioned directly above the two side walls of the steel billet. A guide block is provided on the top surface of the horizontal long plate 17, and an arc-shaped guide groove is provided on the bottom surface of the arc-shaped guide strip 14, with the guide block slidably disposed within the guide groove at the bottom end of the guide strip. The arc-shaped guide strip 14 ensures that the horizontal long plate 17 can reliably rotate around the disc 13.

[0022] The front sensing element includes a front upright 19 and a front infrared rangefinder 20; the front upright 19 is set on the ground on one side of the conveyor roller 1, and the front infrared rangefinder 20 is set on the top end of the front upright 19 near the conveyor roller 1; the signal output terminal of the front infrared rangefinder 20 is connected to the signal input terminal of the CPU; when the front infrared rangefinder 20 senses a sudden decrease in distance, it indicates that the billet is in place.

[0023] The rear sensing element includes a rear upright 21 and a rear infrared rangefinder 22; the rear upright 21 is set on the ground on one side of the conveyor roller 1, and the rear infrared rangefinder 22 is set on the top end of the rear upright 21 near the conveyor roller 1; the signal output terminal of the rear infrared rangefinder 22 is connected to the signal input terminal of the CPU; when the infrared rangefinder 22 senses a signal, the disappearance of the signal indicates that the billet has left.

[0024] The CPU module in this invention is model 87C196KC.

[0025] Operating principle: When the steel billet passes the front infrared rangefinder 20, it is sensed, and then the solenoid valve switch on the long flexible hose is opened to connect the water source, causing the water pipe 18 to spray cooling water downwards. When the steel billet passes the triangular top blocks on both sides, it first hits the hypotenuse of the triangular top blocks, pushing the two vertical plates apart. Under the action of the spring, the push plate is close to the steel billet, ensuring that the triangular top blocks on both sides are pressed against the side walls of the steel billet. During the process of adjusting the distance between the vertical plates on both sides, the horizontal long plate 17 can be adaptively adjusted in position by the rotation guide of the disc 13, the sliding of the slider 16, and the rotation of the round rod, so that its two ends are directly above the side walls of the steel billet. This also ensures that the two ends of the water pipe are directly above the side walls of the steel billet. At this time, the cooling water is continuously sprayed onto the steel billet for cooling treatment. After the steel billet passes the rear infrared rangefinder, the solenoid valve is closed and the spraying stops. At this time, the triangular top blocks on both sides move forward under the action of the spring, waiting for the next steel billet to arrive. This process is repeated to cool the passing steel billets.
