Description

Technical Field

[0001] The present invention relates to the technical field of marine steel processing, and particularly to a numerical control machine tool for processing the end of marine steel. Background Art

[0002] Marine T-shaped steel is a kind of steel with a T-shaped cross-section, which is widely used in ship structures, especially the hull skeleton, frame and support components. The structure has good strength and stability. The main purpose of processing the end of marine T-shaped steel is to ensure the accuracy and adaptability of its connection, reduce assembly errors, improve the safety and durability of the structure. The processed end can be better welded or connected to other components. At present, most of the cutting methods for the end of marine T-shaped steel use plasma cutting. Compared with other cutting methods (such as oxygen cutting or mechanical cutting), plasma cutting has a higher cutting speed, a more precise cutting edge, a 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 the steel, ensure the cutting surface quality and improve the subsequent processing efficiency. In addition, plasma cutting is suitable for thicker materials and produces less pollutants during the cutting process, with better environmental protection.

[0003] Common numerical control machine tools in the prior art generally can only perform plasma pre-cutting or grinding on the end of marine T-shaped steel. After the end of marine T-shaped steel is pre-cut by a plasma cutting machine, it needs to be transferred to a dedicated grinding device for grinding. The transfer process increases the operation complexity and equipment occupancy space, reduces the production efficiency. Secondly, the coordination between multiple devices may lead to machining accuracy errors and time delays, increasing the need for manual intervention and raising the production cost. Moreover, after the end of marine steel is directly stored after grinding, the end of marine steel will rust. The steel surface is easily exposed to moisture and oxygen in the air, resulting in rust. Rust not only affects the appearance of the steel, reduces its corrosion resistance, but may also lead to a decline 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 object of the present invention is to solve the problems in the prior art that common numerical control machine tools can generally only pre-cut or polish 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 polishing device for polishing. This transfer process increases the operational complexity and the occupied space of the equipment, reduces the production efficiency. Secondly, the coordination between multiple devices may lead to machining precision errors and time delays, increasing the need for manual intervention and raising the production cost. Moreover, after the marine steel ends are directly stored after polishing, the marine steel ends will rust. The surface of the steel is easily exposed to moisture and oxygen in the air, resulting in rust. Rust not only affects the appearance of the steel, reduces its corrosion resistance, but may also cause a decline 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.

The sealing magnetic plate is fixedly arranged at the top of the vertical rod.

[0015] A processing method for the end of marine steel includes the following steps:

[0016] S1. Pre-cut and pre-grind the end of the marine steel. The end of the marine steel extends into the top of the common seat by an appropriate distance. Use the numerical control plasma cutting component to cut the end of the marine steel on the top of the stage. The servo motor drives the common seat to flip, driving the grinding component to rotate to one end of the end of the marine steel to grind the end of the marine steel.

[0017] S2. Seal and spray paint the end of the marine steel to prevent rust. The servo motor drives the common seat to flip again, driving the seal spray painting component to rotate to one end of the end of the marine steel. The seal spray painting component can wrap one end of the end of the marine steel and spray paint the end of the marine steel.

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

[0019] 1. In the present invention, a servo motor is fixedly arranged on the side of the inner cavity of the numerical control machine tool. The output end of the servo motor is fixedly provided with a common seat. Four horizontal planes of the common seat are successively provided with a composite processing component for first grinding and then spray painting the end of the steel. The composite processing component includes a seal spray 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, spatter, and oxide layers often appear on the cutting surface, resulting in an uneven cutting surface, and even possible unevenness. Grinding can remove these uneven parts, making the cutting surface smoother and more flat, meeting the accuracy requirements of shipbuilding. The composite processing component can, after the plasma cutting of the end of the marine steel on the numerical control machine tool, successively grind and then spray paint the end of the marine steel on the premise that the whole end of the marine steel does not move, avoiding the cumbersome process of transferring to other equipment in the traditional process. This design enables the end of the steel to complete grinding and spray painting without moving, reducing processing errors and time delays, improving production efficiency. At the same time, the integration of the seal spray painting and grinding functions of the composite processing component not only saves space and cost, but also effectively avoids damage or pollution caused by transfer, improving processing accuracy and product quality.

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

[0021] 3. Inside the common seat of the present invention, a horizontal seat is suspended, and an attracting electromagnet is arranged on the top of the horizontal seat. When the end of the marine steel is being cut by a numerical control machine tool, the attracting electromagnet can assist in processing the end of the marine steel. 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, avoiding the accumulation of waste in the working area and ensuring the cleanliness of the processing environment. This design not only improves the stability and safety during the cutting process but also effectively reduces the workload of manual cleaning and improves the production efficiency.

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

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

[0044] One end of the connecting spring 32 is fixedly connected to the side surface of the connecting ring 33, and the other end of the connecting spring 32 is fixedly connected to the side surface of the docking cylinder 31. The extension pipe 30 is movably inserted into the docking cylinder 31.

An inverted T-shaped groove 251 is provided on one side surface of the sealing box 25 away from the sealing cylinder 34. When the inverted T-shaped groove 251 is set, it is proportional to the cross-sectional size of the side surface of the marine T-shaped steel actually processed. The size of the inverted T-shaped groove 251 is slightly larger than the cross-sectional size of the side surface of the marine T-shaped steel actually processed.

[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 at the top of the sealing box 25, and a docking frame 26 is fixedly provided at the top of the top groove 252.

When the sealing magnetic plate 242 and the pulling magnetic plate 27 are installed, the opposite magnetic surfaces of the sealing magnetic plate 242 and the pulling magnetic plate 27 are opposite. When the pulling magnetic plate 27 moves horizontally, it will pull the sealing magnetic plate 242 to move horizontally through magnetic force.

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

[0047] When the entire device is in the standby state, the sealing cylinder 34 and the grinding cylinder 23 are both in the retracted state. At this time, the pulling magnetic plate 27 will magnetically collect the sealing magnetic plate 242 inside the receiving groove 2411. The docking pipe 28 is externally connected to a painting device. The worker places 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 down the marine T-shaped steel through the pressing seat 18. One end of the marine T-shaped steel extends to the top of the common seat 241, and the end of the marine steel is pre-cut and pre-ground. The end of the marine steel extends an appropriate distance to the top of the common seat 241.

[0048] The attracting electromagnet 221 attracts the end of the marine steel by magnetic force, and the end of the marine steel on the top of the loading platform 10 is cut by the numerical control plasma cutting assembly. The servo motor 24 drives the common seat 241 to flip, driving the grinding assembly to rotate to one end of the 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 attracting electromagnet 221 is powered off. When the common seat 241 flips, the cutting waste will be shaken into the storage box 5.

[0049] When the end of marine steel is sealed and painted for rust prevention, there will be two situations. The servo motor 24 drives the common seat 241 to turn again, driving the seal painting assembly to rotate to one end of the marine steel end, and then starting the seal cylinder 34 to drive the seal box 25 to move horizontally.

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

[0051] When one end of the marine T-shaped steel cannot be correctly inserted into the inverted T-groove 251, the connecting spring 32 will be compressed, the release hole 301 will be staggered with the docking pipe 28, and the external painting equipment will not spray paint on one end of the marine T-shaped steel through the docking pipe 28, the extension pipe 30, and the spray hole 291 of the T-shaped box 29. It should be added that in either of the above situations, when the seal box 25 approaches the marine T-shaped steel, the pulling magnetic plate 27 will temporarily close the bottom of the seal box 25 by magnetic force pulling the seal magnetic plate 242.

[0052] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes should be covered within the protection scope of the present invention.
