Description

Technical Field

[0001] The utility model relates to the field of steel billet production equipment, in particular to a steel billet cutting device. Background Art

[0002] In the continuous casting workshop, the billets on the billet discharging device need to be cut according to customer requirements. At this time, a flame cutting device is needed for cutting.

[0003] A traditional flame cutting device includes: a crossbeam guide rail, and a frame arranged on the crossbeam guide rail and capable of moving back and forth on the crossbeam guide rail, a pair of clamping arms are arranged on the frame, and a cutting gun capable of cutting the steel billet is arranged on the frame located in front of the clamping arms. The frame, the clamping arms, and the cutting gun are respectively controlled by a PLC controller. A travel switch is arranged on the steel billet discharging device, and the travel switch is electrically connected to the PLC controller. When the travel switch senses the steel billet, the travel switch sends a signal to the PLC controller, and the PLC controller controls the clamping arms to clamp the steel billet. The PLC controller simultaneously drives the frame to move forward and the cutting gun to start cutting the steel billet. When the cutting is completed, the PLC controller controls the clamping arms to release the steel billet, and at the same time, the PLC controller controls the cutting gun to stop cutting and controls the frame to move backward to reset to the starting point. However, the flame cutting device of the above structure will encounter the following problems when cutting steel billets: iron oxide impurities will remain on the cut end of the steel billet, making the cut end of the steel billet fail to meet the process requirements, and the staff needs to perform a second cutting process on the cut end of the steel billet, which not only increases the workload and reduces production efficiency, but also causes waste and increases production costs.

[0004] Therefore, this field needs a new technical solution to solve the above problems. Summary of the invention

[0005] In order to improve or solve the technical problem in the prior art that the cutting slag remains on the steel billet after cutting, resulting in the steel billet not meeting the process requirements, the utility model provides a steel billet cutting device. The steel billet cutting device comprises: a cutting clamp arm, which is suitable for clamping the steel billet and moving under the drive of a driving device; a cutting gun, which is installed on the cutting clamp arm; a purge structure, which is installed on the cutting clamp arm and comprises a support frame fixed on the cutting clamp arm, a pipe fixed on the support frame, a nozzle installed on the end of the pipe, and a solenoid valve installed on the pipe; a compressed air source is connected to one end of the pipe away from the nozzle, and the solenoid valve is configured to open when the cutting clamp arm clamps the steel billet and close after the cutting clamp arm releases the steel billet.

[0006] The utility model steel billet cutting device includes a cutting clamp arm, a cutting gun and a purging structure. The cutting clamp arm is used to clamp the steel billet and move under the drive of the driving device, and is also a mounting frame for other components. The cutting gun is generally connected to a power source such as propane and natural gas for cutting the steel billet. The purging structure is installed on the cutting clamp arm and is used to purge the cutting slag remaining on the steel billet. The support frame is fixed on the cutting clamp arm and is used to support the pipeline and the nozzle. One end of the pipeline is connected to the compressed air source, and the other end is connected to the nozzle for conveying compressed air. The battery valve is installed on the pipeline, opened after the cutting clamp arm clamps the steel billet, and closed after the cutting clamp arm releases the steel billet; wherein, when the cutting clamp arm clamps the steel billet, it is ready to cut the steel billet; when the cutting clamp arm releases the steel billet, the steel billet cutting is completed. Through the above-mentioned setting, the utility model steel billet cutting device can purge the cutting slag formed on the steel billet when the steel billet is cut, so that the steel billet meets the process requirements, avoids secondary treatment of the cutting slag, improves production efficiency, and reduces production costs.

Through the above-mentioned arrangement, the arrangement of the air pressure detection gauge can more conveniently monitor the air pressure in the pipeline to prevent pipeline leakage or insufficient air pressure, which affects the purging effect of the cutting slag.

[0010] In the preferred technical solution of the above-mentioned steel billet cutting device, a spray structure is also included, the spray structure includes a water pipe and a water spray head arranged at one end of the water pipe, the water spray head is suitable for facing the lower surface of the steel billet. Through the above-mentioned arrangement, the arrangement of the spray structure can more conveniently cool the cutting slag.

[0011] In the preferred technical solution of the above-mentioned steel billet cutting device, a waste trough for collecting cutting slag is arranged below the cutting gun. Through the above-mentioned arrangement, the arrangement of the waste trough can more conveniently collect the cutting slag, thereby uniformly processing the cutting slag.

[0012] In the preferred technical solution of the above-mentioned billet cutting device, an industrial camera for detecting cutting slag on the billet surface is also arranged on one side of the cutting clamp arm; the industrial camera is arranged on one side of the purge structure, and is configured to detect the remaining cutting slag after the purge structure cleans the cutting slag. Through the above-mentioned setting, the arrangement of the industrial camera can detect the remaining cutting slag, so that when there is too much cutting slag remaining, the billet surface is purged again.
