Description

Technical Field

[0001] This utility model relates to the field of wire rod production equipment in the metallurgical industry, specifically to a sliding guide for a high-speed wire rod rolling production line. Background Technology

[0002] In hot-rolled wire rod production lines, due to the large volume of cooling water and the small size of the rolled pieces, especially when producing high-carbon steel with a specification of Φ5.5-6.5, the steel head cools rapidly upon contact with water during the rolling process. When biting into the next stand of rolls, it is prone to slippage and steel piling, or cracking and slag falling off the head, which can lead to other production accidents. Existing sliding guides contain cooling water, and the rolled piece inevitably comes into contact with water when passing through the sliding guide, causing blackening at the head of the rolled piece, resulting in production accidents, reduced yield, and increased production costs. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and propose a sliding guide for a high-speed wire rod rolling production line. This guide can clean the cooling water inside the sliding guide, prevent the rolled piece from coming into contact with water, avoid production accidents caused by black spots on the head of the rolled piece, improve the yield, and reduce production costs.

[0004] To achieve the above objectives, the present invention proposes the following technical solution:

[0005] A sliding guide for a high-speed wire rod rolling production line includes a guide body, a pneumatic nozzle, and a pressure regulating device. The guide body includes a guide inlet and a guide outlet. An inclined channel is provided on the guide body between the guide inlet and the guide outlet. The inclined channel is inclined at an angle of 25-35° to the axis of the rolling passage of the guide body. The pneumatic nozzle is installed at the opening of the inclined channel and is connected to an external high-pressure air source. The inner diameter of the pneumatic nozzle is 8-12 mm, and the air pressure is 5-8 bar. The pressure regulating device is used to regulate and control the outlet air pressure of the pneumatic nozzle.

[0006] The air pressure regulating device includes a filter, a pressure regulating valve, and a pressure gauge, which are sequentially installed on the pipeline between the high-pressure air source and the pneumatic nozzle. The filter is located at the front end of the pressure regulating valve and is used to filter moisture, oil, and particulate matter in the compressed air to prevent the pneumatic nozzle from clogging. The pressure regulating valve stabilizes the output pressure and resists fluctuations in the air source or changes in the load. The pressure regulating valve is an electrically controlled proportional valve. The pressure gauge is used to monitor the actual output air pressure, and the pressure value of the pressure regulating valve can be adjusted according to the actual pressure value displayed by the pressure gauge.

[0007] Preferably, the inclined channel is inclined at a 30° angle to the axis of the rolling channel of the guide body, the diameter of the pneumatic nozzle is 10 mm, and the air pressure is 7 bar.

[0008] Preferably, two sets of inclined channels are symmetrically arranged along the axial direction of the rolling channel of the guide body, located at the top and bottom of the guide body respectively, to further optimize the cleaning effect of cooling water.

[0009] Preferably, the air pressure regulating device further includes a small air storage tank located between the high-pressure air source and the filter, which serves as a buffer tank to buffer air pressure fluctuations and ensure continuous and stable purging airflow.

[0010] Preferably, the system also includes a PLC controller. The input terminal of the PLC controller is connected to the pressure gauge, and the output terminal of the PLC controller is connected to the opening actuator of the pressure regulating valve through a servo motor. The PLC controller sends instructions to the servo motor according to the actual pressure value, and the servo motor drives the opening actuator to adjust the opening of the pressure regulating valve through a mechanical transmission mechanism, thereby accurately controlling the air pressure.

[0011] Preferably, the device also includes a PLC controller, an infrared temperature sensor located at the guide outlet, and a high-speed camera located on one side of the guide outlet. The infrared temperature sensor monitors the temperature of the workpiece head in real time, and the high-speed camera captures the surface condition of the workpiece head, such as black spots or cracks. The infrared temperature sensor and the high-speed camera are connected to the input terminal of the PLC controller, and the output terminal of the PLC controller is connected to the opening actuator of the pressure regulating valve through a servo motor. Based on the workpiece head temperature monitored by the infrared temperature sensor and the surface condition captured by the high-speed camera, the PLC controller sends a command to the servo motor. The servo motor drives the opening actuator to adjust the opening of the pressure regulating valve through a mechanical transmission mechanism, dynamically adjusting the output pressure of the air pressure regulating device to ensure the quality of the workpiece.

[0012] The PLC controller, infrared temperature sensor, and high-speed camera mentioned above are existing technologies.

[0013] The beneficial effects of this utility model are as follows:

[0014] This invention features inclined channels at the guide inlet and outlet, with pneumatic nozzles installed at the openings of these channels and connected to an external high-pressure air source. A pressure regulating device controls the outlet pressure of the pneumatic nozzles, effectively cleaning the cooling water inside the sliding guide, preventing the rolled piece from contacting water, avoiding production accidents caused by blackheads on the rolled piece head, improving yield, and reducing production costs.

[0015] This invention optimizes the cleaning effect of cooling water and accelerates the cleaning efficiency by setting two sets of inclined channels, which are symmetrically located at the top and bottom of the guide body along the axial direction of the rolling channel.

[0016] This invention uses a PLC controller connected to a pressure gauge and a pressure regulating valve actuator. The PLC control can adjust the opening of the pressure regulating valve according to the actual pressure value, thereby accurately controlling the air pressure and ensuring the cleaning effect of the cooling water.

[0017] This invention incorporates a PLC controller, an infrared temperature sensor, and a high-speed camera. The PLC controller adjusts the opening of the pressure regulating valve based on the temperature of the rolled piece head monitored by the infrared temperature sensor and the surface condition captured by the high-speed camera, thereby dynamically regulating the output pressure of the air pressure regulating device to ensure the quality of the rolled piece.

[0018] By adopting the above solution, this utility model can clean the cooling water inside the sliding guide, prevent the rolled piece from coming into contact with water, avoid production accidents caused by black spots on the head of the rolled piece, improve the yield, and reduce production costs.
