Description

Technical Field

[0001] The present invention belongs to the technical field of smelting, and in particular relates to a steel billet counting device. Background Art

[0002] Steelmaking involves controlling the carbon content to generally less than 2%, eliminating harmful elements such as P, S, O, and N, retaining or increasing beneficial elements such as Si, Mn, Ni, and Cr, and adjusting the ratios between these elements to achieve optimal performance. Pig iron for steelmaking is placed in a steelmaking furnace and smelted according to a specific process to produce steel. Steel products include ingots, continuous casting billets, and various directly cast steel castings. Steel, as commonly referred to, generally refers to steel rolled into various steel grades. Although steel is classified as a ferrous metal, it is not completely equivalent to ferrous metals. In the current steelmaking process, billets are pulled from the continuous caster and cut. After cutting, the billets are pulled from each stream onto a cooling bed, where they are continuously tumbled and cooled by convection with the air. They are then hoisted by an overhead crane to complete the production process.

[0003] The steelmaking technology currently on the market is prone to quality problems during the steelmaking process. It is difficult to determine at which stage the quality problem occurs in the steel billet, and it is difficult to find the steel billet with quality problems, which is time-consuming and laborious. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the present invention provides a billet counting device, which solves the problem of the current steelmaking technology on the market. Quality problems are prone to occur during the steelmaking process, and it is difficult to determine which specific flow of the billet with the problem is caused.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] The top of described sliding panel also is provided with an interlocking structure, and the interlocking structure of described sliding panel also is provided with an interlocking structure, and the interlocking structure of described sliding panel also is provided with an interlocking structure. The top surface of the cylinder head is fixedly connected to the joint, and the top surface of the joint is fixedly connected to the intake pipe, and the surface of the intake pipe is fixedly connected to the shell. The inner wall of the shell is provided with a limiting groove, and the outer surface of the shell and the inner wall are penetrated by the exhaust port, and the inner wall of the shell is rotatably connected to the exhaust pipe, the surface of the exhaust pipe is fixedly connected to the limiting column, and the surface of the exhaust pipe and the inner wall are penetrated by the through hole, the first gear is fixedly installed on the side of the exhaust pipe, the surface of the intake pipe is fixedly connected to the motor, and the motor is fixedly connected to the shell, the output end of the motor is fixedly connected to the second gear, the end of the intake pipe is fixedly connected to the solenoid valve, a coil is wound on the surface of the solenoid valve, and the solenoid valve is fixedly connected to the PLC through the coil.

[0007] Preferably, the cylinder head and the cylinder bottom are both circular plate structures, and the cylinder head and the cylinder bottom are equal in size.

[0008] Preferably, the first gear is meshed with the second gear, and the radii of the first gear and the second gear are equal.

[0009] Preferably, the cylinder is a circular tubular structure, and the piston is a circular plate structure.

[0010] Preferably, there are two air ports, and both of the air ports penetrate the surface and inner wall of the cylinder bottom.

[0011] Preferably, the vent has a radius equal to that of the through hole, and both the housing and the air outlet pipe are circular tubular structures.

[0012] Compared with the prior art, the beneficial effects of the present invention are: when the billet counting device is cut and advances to a certain length, the PLC outputs a signal to control the solenoid valve to be turned on, the solenoid valve is actuated, and compressed gas enters the cylinder through the air supply port and the working port of the solenoid valve. The compressed gas compresses the piston in the cylinder, and the piston generates pressure downward and is pressed down through the connecting rod. However, because the tenon is stuck by the positioning pin and cannot move downward, the PLC outputs a signal, and the tripping motor starts to rotate, driving the cam to rotate. When the cam rotates, it hits the positioning rod and causes the positioning rod to retreat. The positioning rod drives the positioning pin backward, causing it to disengage from the tenon. The piston pushes the connecting rod downward, driving the pressure head and the punch to press downward, punching an impression on the billet. At the same time, the PLC controls the solenoid valve to close, and the motor drives the second gear to rotate, driving the first gear and the bleed pipe to rotate, so that the bleed port and the through hole are aligned, and the compressed gas can be released. The piston begins to rise under the action of the spring and drives the connecting rod to rise. During the rising process, the tenon pushes the positioning pin. When the tenon rises above the positioning pin, the positioning pin returns to its position under the action of the reset spring, and each component returns to its initial state, waiting for the next cycle to run. When the tripping motor returns to its original position, the positioning cam hits the contact point, and the billet can be numbered. This achieves the goal of facilitating the determination of which link in the billet has quality problems, and can quickly find the billet with problems, reducing the time staff spend searching when problems occur with the billet.

[0020] The electrical components mentioned in this article are all connected to an external main controller and 220V AC power, and the main controller can be a conventional known device that performs control such as a computer.

[0021] Working principle: The steel billet 1 is cut by the flame and conveyed forward by the conveyor roller 2. The PLC19 starts to control the solenoid valve 17. The solenoid valve 17 is activated. The compressed gas in the air supply port passes through the solenoid valve 17, the working port, and the connector 20 into the cylinder 7. The compressed gas presses the piston 4 downward, and the piston 4 presses the connecting rod 5 downward. There is a tenon 9 on the connecting rod 5. The tenon 9 is stuck by the positioning pin 13, causing the piston 4 and the connecting rod 5 to be unable to move downward. When the PLC19 determines that the steel billet 1 has moved to the appropriate part, the PLC 19 starts to output a signal to control the tripping motor 16 to start running. The tripping motor 16 drives the cam 15 to rotate. When the cam 15 rotates, the positioning rod 14 is pushed open. The positioning rod 14 drives the positioning pin 13 to retreat. At the same time, the reset spring 12 is compressed. When the positioning pin 13 is disengaged from the tenon 9, the compressed gas in the cylinder 7 pushes the piston 4 to move downward. The movable 4 pushes the connecting rod 5 downward. The connecting rod 5 pushes the pressure head 10 downward. A punch 11 is installed under the pressure head 10. There is a flow number mark on the punch 11. When the punch is pressed, the piston 4 moves downward. When the head 11 is pressed onto the billet 1, it leaves an imprint on the billet 1. After the above actions are completed, the PLC 19 controls the solenoid valve 17 to operate, and the second gear 27 is driven to rotate by the motor 26, which drives the first gear 25 and the bleed pipe 24 to rotate, so that the bleed port 28 is aligned with the through hole 29, so that the gas in the cylinder 7 is discharged. The spring 6 pushes the piston 4, the connecting rod 5, the pressure head 10, the punch 11 and the tenon 9 to start upward, and the release motor 16 drives the cam 15 to release the positioning pin 13 from the tenon 9. Continue running, the positioning pin 13 gradually returns to its original position under the action of the reset spring 12. When the tenon 9 passes through the positioning pin 13, the tenon 9 is buckled by the positioning pin 13 and cannot go down. When the piston 4, connecting rod 5, punch pressure head 10, punch 11 and tenon 9 return to their original positions under the action of the spring 6 and prepare for the next action, after the tripping motor 16 turns to its original position, the positioning cam 21 presses against the positioning contact 18, the PLC19 system receives the signal, the tripping motor 16 stops rotating, and prepares for the next action.
