Description

Technical Field

[0001] The invention relates to the technical field of ship steel processing, in particular to a numerical control machine tool for processing the ends of ship steel. Background Art

[0002] Marine T-steel is a kind of steel with T-shaped cross section, which is widely used in ship structures, especially the skeleton, frame and supporting parts of the hull. The structure has good strength and stability. The main purpose of processing the ends of marine T-steel is to ensure the accuracy and adaptability of its joints, reduce assembly errors, and improve the safety and durability of the structure. The processed ends can be better welded or connected with other parts. At present, plasma cutting is mostly used for cutting the ends of marine T-steel. Compared with other cutting methods (such as oxygen cutting or mechanical cutting), plasma cutting has higher cutting speed, more precise cutting edge, smaller heat-affected zone and less deformation. The heat generated by plasma cutting is concentrated, which can effectively reduce the oxide layer and burrs of steel, ensure the quality of cutting surface, and improve the efficiency of subsequent processing. In addition, plasma cutting is suitable for thicker materials, less pollutants are generated during the cutting process, and it is more environmentally friendly.

[0003] Common CNC machine tools in the prior art can generally only perform plasma pre-cutting or grinding on the ends of marine T-shaped steel. After the ends of marine T-shaped steel are pre-cut by plasma cutting machines, they need to be transferred to special grinding equipment for grinding. The transfer process increases the complexity of operation and the space occupied by equipment, reducing production efficiency. Secondly, the coordination between multiple devices may lead to processing accuracy errors and time delays, increase the need for manual intervention, and increase production costs. After the ends of marine steel are directly stored after grinding, the ends of marine steel will rust. The surface of steel is easily exposed to moisture and oxygen in the air, causing rust. Rust not only affects the appearance of steel and reduces its corrosion resistance, but may also cause a decrease in mechanical properties, affecting the overall safety and service life of the ship structure. In addition, the rust layer will increase the difficulty of subsequent processing and require additional cleaning work. Summary of the invention

[0004] The purpose of the present invention is to solve the problem that the commonly used CNC machine tools in the prior art can generally only pre-cut or grind the ends of marine T-shaped steel. After the ends of marine T-shaped steel are pre-cut by a plasma cutting machine, they need to be transferred to a dedicated grinding device for grinding.

Secondly, the coordination between multiple devices may lead to processing accuracy errors and time delays, increase the need for manual intervention, and increase production costs. In addition, after the ends of marine steel are directly stored after grinding, the ends of marine steel will rust. The surface of the steel is easily exposed to moisture and oxygen in the air, causing rust. Rust not only affects the appearance of the steel and reduces its corrosion resistance, but also may cause a decrease in mechanical properties, affecting the overall safety and service life of the ship structure.

[0015] A method for processing the end of a ship steel material comprises the following steps:

[0016] S1, pre-cutting and pre-grinding of the ends of the marine steel, the ends of the marine steel extend into the top of the common seat at an appropriate distance, and the ends of the marine steel on the top of the stage are cut by a CNC plasma cutting assembly, and the servo motor drives the common seat to flip, and drives the grinding assembly to rotate to one end of the marine steel end, and grinds the ends of the marine steel;

[0017] S2, the end of the marine steel is sealed and sprayed with paint to prevent rust. The servo motor drives the common seat to flip again, driving the sealing spray painting assembly to rotate to one end of the marine steel end. The sealing spray painting assembly can wrap one end of the marine steel end and paint the marine steel end.

[0018] Compared with the prior art, the present invention has the following advantages:

[0019] 1. The present invention has a servo motor fixedly arranged on the side of the inner cavity of the CNC machine tool, a common seat fixedly arranged on the output end of the servo motor, and four horizontal surfaces of the common seat are sequentially provided with a composite processing component for first grinding and then painting the end of the steel material, the composite processing component includes a sealing and painting component and a steel end face grinding component. During the plasma cutting process, due to the action of the high-temperature plasma arc, slag, sputtering and oxide layer often appear on the cutting surface, resulting in an uneven cutting surface, and even unevenness. Grinding can remove these uneven parts, making the cutting surface smoother and smoother, meeting the precision requirements of shipbuilding. After the composite processing component is set on the CNC machine tool for plasma cutting of the ship steel end, on the premise that the entire ship steel end does not move, the end of the ship steel can be grinded and then painted in sequence, thereby avoiding the cumbersome process of transferring to other equipment in the traditional process. This design enables the steel ends to be polished and painted without moving, reducing processing errors and time delays and improving production efficiency. At the same time, the integration of sealing, painting and polishing functions of the composite processing components not only saves space and cost, but also effectively avoids damage or contamination caused by transfer, thereby improving processing accuracy and product quality.

[0020] 2. One of the core components of the composite polishing assembly of the present invention is a sealed spray-painting assembly. The sealed spray-painting assembly can first wrap one end of the marine steel to be painted, and complete the spray-painting and rust prevention of the end of the marine steel in a smaller sealed space. The sealed space can effectively control the airflow and spray diffusion during the painting process, avoid paint waste and environmental pollution, and improve the uniformity of the coating. The sealed environment can reduce the entry of external moisture, impurities or dust in the air into the painting area, ensure the quality of the coating, and extend the anti-corrosion effect of the steel. Finally, the sealed spray-painting can also control the temperature and humidity during painting, further improving the anti-rust effect.

[0021] 3. A horizontal seat is suspended inside the common seat of the present invention, and an attraction electromagnet is arranged on the top of the horizontal seat. The attraction electromagnet can assist the end of the marine steel when the end of the entire marine steel is cut by the CNC machine tool. When the servo motor drives the common seat to rotate and switch its function, the cutting waste will be released and dumped into the storage box at the same time to avoid the accumulation of waste in the working area and ensure the cleanliness of the processing environment. This design not only improves the stability and safety of the cutting process, but also effectively reduces the workload of manual cleaning and improves production efficiency.

[0022] 4. One of the core components of the composite polishing assembly of the present invention is a sealed spray paint assembly. The sealed spray paint assembly has error correction. When an inverted T-groove is provided on the side of the sealed spray paint assembly's sealing box, when the processing end of the marine T-steel fails to be correctly inserted into the inverted T-groove, so that the processing end of the marine T-steel fails to be wrapped by the sealed spray paint assembly, the sealed spray paint assembly cannot spray paint, and the sealed box is in a state of connection with the outside world, thereby preventing the paint spray system from starting in a non-sealed environment. This design not only ensures high precision and coating quality during the painting process, but also effectively protects the environment. Since painting can only be carried out in a closed sealed space, the leakage of harmful substances during the painting process is avoided, and the pollution to the air and the impact on the surrounding environment are reduced. This closed environment ensures that the painting operation will not be disturbed by external dust, moisture, etc., and further improves the uniformity and durability of the coating.

[0023] 5. In order for the marine T-steel to fit the side of the common seat during processing and for the sealing box to be correctly connected with the processing end of the marine T-steel, the bottom of the sealing box must be set to an open surface. Therefore, when the sealing box is sealed and sprayed, an auxiliary sealing assembly composed of a sealing magnetic plate and a pulling magnetic plate is set at the bottom of the sealing box. When the sealing box is close to the marine T-steel, the pulling magnetic plate will temporarily close the bottom of the sealing box due to the magnetic force of pulling the sealing magnetic plate. When the pulling magnetic plate is not needed, it retracts onto the common seat to avoid being cut by the laser emitted by the plasma cutting machine. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] The auxiliary sealing assembly includes a pulling magnetic plate 27, a sealing magnetic plate 242, and a vertical rod 2420. A top groove 252 is provided on the top of the sealing box 25. A docking frame 26 is fixedly provided on the top of the top groove 252. The top of the docking frame 26 is fixedly connected with the pulling magnetic plate 27. The common seat 241 is provided with a receiving groove 2411 at the lower edge of the sealing box 25. A transverse groove 2410 is provided at the midline position of the receiving groove 2411.

The top view cross-sectional dimensions of the sealing magnetic plate 242 and the accommodating groove 2411 are the same. The accommodating groove 2411 is used to accommodate the sealing magnetic plate 242. When the sealing magnetic plate 242 and the pulling magnetic plate 27 are installed, the magnetic properties of the opposite surfaces of the installed sealing magnetic plate 242 and the pulling magnetic plate 27 are opposite. When the pulling magnetic plate 27 moves transversely, the sealing magnetic plate 242 will be pulled transversely by magnetic force.

[0046] The specific implementation steps and principles of the present invention are as follows:

[0047] When the entire device is in standby state, the sealing cylinder 34 and the grinding cylinder 23 are both in a retracted state. At this time, the pulling magnetic plate 27 will store the sealing magnetic plate 242 in the accommodating groove 2411 through magnetic force, and the docking tube 28 is connected to the external painting equipment. The worker puts the marine T-shaped steel to be processed on the top of the loading platform 10 and starts the vertical cylinder 19. The vertical cylinder 19 will press the marine T-shaped steel down through the holding seat 18. One end of the marine T-shaped steel extends to the top of the common seat 241. The end of the marine steel is pre-cut and pre-grinded, and the end of the marine steel extends to the top of the common seat 241 at an appropriate distance.

[0048] The attraction electromagnet 221 uses magnetic force to attract the end of the marine steel, and uses the CNC plasma cutting component to cut the end of the marine steel on the top of the stage 10. The servo motor 24 drives the common seat 241 to flip, and drives the grinding component to rotate to one end of the marine steel to grind the end of the marine steel. At the same time, when the servo motor 24 is started, the attraction electromagnet 221 is powered off, and when the common seat 241 flips, the cutting waste will be shaken into the storage box 5.

[0049] When the end of the marine steel is sealed and sprayed for rust prevention, there are two situations. The servo motor 24 drives the common seat 241 to flip again, drives the sealing spray paint assembly to rotate to one end of the marine steel end, and starts the sealing cylinder 34 to drive the sealing box 25 to move horizontally.

[0050] When one end of the marine T-steel is correctly inserted into the inverted T-slot 251, the connecting spring 32 will not be compressed, the release hole 301 is aligned with the docking tube 28, and the external painting equipment will spray paint on one end of the marine T-steel through the spray hole 291 of the docking tube 28, the extension tube 30, and the T-box 29.

[0051] When one end of the marine T-steel cannot be correctly inserted into the inverted T-slot 251, the connecting spring 32 will be compressed, the release hole 301 will be staggered with the docking tube 28, and the external painting equipment will not spray paint to one end of the marine T-steel through the docking tube 28, the extension tube 30, and the spray hole 291 of the T-box 29. It should be added that no matter which of the above situations is the case, when the sealing box 25 is close to the marine T-steel, the pulling magnetic plate 27 will temporarily close the bottom of the sealing box 25 due to the magnetic force pulling the sealing magnetic plate 242.

[0052] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
