Description

Technical Field

[0001] The present invention relates to the technical field of metal processing, in particular to a cutting device and a cutting method for angle iron production. Background Art

[0002] Angle iron, a common metal profile, is widely used in numerous industrial fields, including construction, machinery manufacturing, and power equipment installation. Typically manufactured through a rolling process, angle irons possess a specific cross-sectional shape, providing stable support and connection for structures. Cutting is a critical step in the production and processing of angle irons, requiring them to be cut into segments of varying lengths based on actual needs.

[0003] Currently, there are a variety of angle iron cutting equipment on the market, and these equipment are constantly improving in terms of cutting efficiency and cutting precision. However, most existing angle iron cutting equipment focuses on improving cutting speed and ensuring the accuracy of cutting dimensions, and pays less attention to the problem of oxidation and rusting on the cut surface of the angle iron after cutting.

[0004] During the cutting process, the cross-section of angle iron will be exposed to the air. Since angle iron is usually made of iron, iron easily reacts chemically with oxygen and water in the air, causing oxidation and rust on the cross-section. Oxidation and rust will not only affect the appearance quality of the angle iron, but more importantly, it will reduce the strength and corrosion resistance of the angle iron, thereby affecting the safety and service life of the entire structure. For example, in a building structure, if the cross-section of the angle iron is rusted, it may cause the connection to loosen and affect the stability of the structure; in the installation of power equipment, rusty angle iron may affect the normal operation of the electrical equipment and even cause safety accidents; In addition, existing angle iron cutting equipment also has some problems with the conveying and positioning of angle irons during the cutting process. When conveying angle irons, they are prone to slippage, resulting in inaccurate cutting lengths; during the cutting process, the angle irons may bend, affecting the cutting quality. These problems have restricted the performance improvement and application scope of angle iron cutting equipment. In view of the above problems, the present invention document proposes a cutting device and a cutting method for angle iron production. Summary of the Invention

[0020] S6. Coating drying: After spraying the protective coating, the conveyor belt continues to drive the angle iron to move, so that both ends of the angle iron pass through the heat generated by the electric heating racks in the installation boxes on both sides to dry and form a protective coating.

[0021] It should be understood that the foregoing general description and the following detailed description are exemplary only and are not restrictive of the invention.

[0022] Beneficial effects: In the present invention, by providing a transmission assembly, the angle iron to be cut can be passed through the two mounting bases and placed on the two driving wheels. Then, the angle iron can be pressed and limited by operating the two pressing members so that the angle iron is in close contact with the two driving wheels. Then, the No. 1 driving motor can be started to drive one of the driving wheels to rotate. Then, under the transmission action of the two synchronous wheels and the synchronous belt, the other driving wheel can be rotated synchronously. Therefore, the two driving wheels that keep rotating can stably drive the angle iron to move. By displacing the angle iron, the angle iron can be cut conveniently. In the present invention, the limit seat can be set in the support frame through the setting of the limit assembly, and the No. Ⅱ clamping plate is clamped with the clamping hole, and then the positioning member is operated to clamp the positioning member with the clamping slot, so that the limit seat can be positioned, and then the angle iron is passed through the positioning hole, and the angle iron is wrapped with the limit seat. When the angle iron is cut, it can avoid shaking of the angle iron, thereby keeping the cutting position accurate, and the limit seat can be disassembled and assembled, so in this technical solution, if Figure 10 As shown, multiple limit seats of different specifications can be configured according to processing requirements, and the apertures of the positioning holes on the multiple limit seats are kept expanding in sequence, so that different limit seats can be selected when cutting angle irons of different thicknesses to wrap and limit the angle irons; In the present invention, the moving assembly is provided to drop the cut angle iron into the corresponding triangular groove, and then the stepping motor is started to drive the active roller to rotate. At this time, with the support and cooperation of the driven roller, the conveyor belt can be driven to move, thereby driving the angle iron to move, so that the protective coating can be sprayed on the cross-sections of the two ends of the angle iron by the spraying assembly; In the present invention, the spraying assembly is provided, and the connecting conduit can be connected to the external pipe for conveying the protective coating, and then the conveying pump is started to convey the protective coating into the connecting box. After that, the protective coating can be sprayed out from the two nozzles through the conveying of the two conveying conduits. Therefore, when the cut angle iron is moved to the position corresponding to the two nozzles, the protective coating can be sprayed on the cross-sections at both ends of the angle iron. After spraying, the angle iron is kept moving, and the heat generated by the electric heating racks in the installation boxes on both sides can be used to dry the two ends of the angle iron to form a protective coating. After the angle iron is cut, the problem of oxidation and rust on the cut cross-section can be avoided.

[0023] The present invention can stably transport the angle iron when cutting the angle iron, and can stably limit the angle iron during the cutting process, thereby preventing the angle iron from being displaced during the cutting process. At the same time, after the angle iron is cut, a protective coating can be sprayed on the cross-section surfaces at both ends of the angle iron, thereby forming a protective effect on the end face of the angle iron and avoiding the problem of rust.

[0026] The embodiments of the present invention are described below with reference to the accompanying drawings.

[0027] In the description of the embodiments of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms, "connection", and "installation" should be understood in a broad sense. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. In addition, "communication" can be a direct connection or an indirect connection through an intermediate medium. Here, "fixed" means that the two are connected to each other and the relative position relationship after connection remains unchanged. The directional terms mentioned in the embodiments of the present invention, such as "inside", "outside", "top", "bottom", etc., are only reference to the directions of the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of the present invention, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the embodiments of the present invention.

[0028] In one embodiment: Figure 1-10A cutting device includes a cutting mechanism and a protective mechanism. In the cutting mechanism, an operating table 1 serves as the basic support structure, and a support roller 2 is rotatably connected to one side of its top through a bearing to support the angle iron. A transmission component and a limit component are also installed on the top of the operating table 1. The transmission component consists of two mounting bases 3 fixed to the top of the operating table 1. Each mounting base 3 is rotatably connected to a drive wheel 4 through a bearing. The drive wheel 4 is concave to better contact the angle iron. A No. 1 drive motor 5 is fixedly installed at the bottom of one side of one of the mounting bases 3. Its output shaft extends into the mounting base 3 and is fixedly connected to one end of the corresponding drive wheel 4. The other end of the drive wheel 4 passes through the inner wall of one side of the mounting base 3 and extends to the outside of the mounting base 3. Both drive wheels 4 are fixedly sleeved with a synchronous wheel 6 located on the outside of the two mounting bases 3, and the transmission sleeves of the two synchronous wheels 6 are provided with the same synchronous belt 7. A pressing component is also installed in the mounting base 3, and the pressing component includes a pressure wheel 9 (made of high-strength rubber (hardness Shore A 70-80), which increases friction). The cross-section of the pressure wheel 9 is diamond-shaped and can contact the inner wall of the angle iron. Adjustment holes are provided on the inner walls on both sides of the mounting base 3, and an adjustment base plate 8 is slidably connected in the adjustment hole. The two ends of the pressure wheel 9 are rotatably connected to the corresponding adjustment base plates 8 respectively. The top of the two adjustment base plates 8 is fixedly installed with the same connecting frame 10, and the top of the connecting frame 10 is rotatably connected with an adjusting screw 11. An adjusting nut 12 is fixedly installed on the top of the mounting base 3, and the top end of the adjusting screw 11 passes through the top inner wall of the mounting base 3 and the adjusting nut 12 respectively and extends to the top of the adjusting nut 12. The adjusting screw 11 is threadedly connected to the adjusting nut 12. After the angle iron to be cut is passed through the two mounting bases 3 and placed on the two driving wheels 4, the adjusting screw 11 is rotated, and the threaded transmission action of the adjusting nut 12 drives the connecting frame 10 downward, thereby driving the pinch wheel 9 downward, so that the pinch wheel 9 is in close contact with the inner side of the angle iron. Thus, under the cooperation with the driving wheels 4, the angle iron is stably clamped and limited, so that the angle iron will not slip when driven by the driven wheels 4. Then, the No. 1 driving motor 5 can be started to drive one of the driving wheels 4 to rotate. Then, under the transmission action of the two synchronous wheels 6 and the synchronous belt 7, the other driving wheel 4 can be rotated synchronously. Therefore, the two driving wheels 4 that keep rotating can stably drive the angle iron to move. By displacing the angle iron, the angle iron can be cut conveniently.

[0029] like Figure 4As shown, the limit assembly includes a support frame 13 fixedly mounted on the top of the operating table 1, with a limit seat 17 provided inside the support frame 13. The limit seat 17 has a positioning hole 18 formed therein. The angle iron passes through the positioning hole 18 and fits tightly against the inner wall of the positioning hole 18. A positioning member is connected to the inner wall of one side of the support frame 13. The positioning member includes a positioning screw 15 that passes through the inner wall of one side of the support frame 13 and is threadedly connected to the inner wall of one side of the support frame 13. One end of the positioning screw 15 located inside the support frame 13 is rotatably connected to a clamping plate 14 via a bearing. The clamping plate 14 is slidably connected to the inner wall of the support frame 13. A No. 1 clamping plate 16 is fixedly mounted on one side of the clamping plate 14. A slot is provided on one side of the limit seat 17, one side of the No. I clamping plate 16 extends into the slot and is movably engaged with the slot, and a No. II clamping plate 20 is fixedly installed on the other side of the limit seat 17. A clamping hole 19 is provided on one inner wall of the support frame 13, and one side of the No. II clamping plate 20 extends into the clamping hole 19 and is movably engaged with the clamping hole 19. After the selected limit seat 17 is set in the support frame 13 and the No. II clamping plate 20 is engaged with the clamping hole 19, the positioning screw 15 is rotated. At this time, under the action of the thread transmission with the inner wall of one side of the support frame 13, the positioning screw 15 can be moved, and the pressing plate 14 can be driven to move, so that the No. I clamping plate 16 is inserted into the slot and engaged with the slot, thereby positioning the limit seat 17. Then, the angle iron is passed through the positioning hole 18. The angle iron is wrapped by the limit seat 17 to prevent the angle iron from shaking when cutting, thereby maintaining the cutting position accurately. In addition, the limit seat 17 can be disassembled and assembled, and multiple limit seats 17 of different specifications can be configured according to processing requirements, and the apertures of the positioning holes 18 on the multiple limit seats 17 can be expanded in sequence, so that different limit seats 17 can be selected when cutting angle irons of different thicknesses to wrap and limit the angle irons.

[0030] like Figure 3 and Figure 6As shown, a fixed frame 21 is fixedly installed on the top of the operating table 1. The fixed frame 21 is fixedly connected to one side of the support frame 13. A movable seat 22 is slidably connected inside the fixed frame 21. A No. II drive motor 24 is fixedly installed on one side of the movable seat 22. The output shaft of the No. II drive motor 24 passes through the movable seat 22. The annular cutter 25 is located on the outside of the fixed frame 21. An electric push rod 23 is fixedly installed on one side of the fixed frame 21. The output shaft of the electric push rod 23 extends into the fixed frame 21 and is fixedly connected to the movable seat 22. The sliding connection between the movable seat 22 and the fixed frame 21 can realize the lateral sliding limit of the annular cutter 25. When it is necessary to cut the angle iron, the No. II drive motor 24 and the electric push rod 23 can be started. When the No. II drive motor 24 rotates, the annular cutter 25 can be driven to rotate at high speed. When the electric push rod 23 is running, it can drive the movable seat 22 to move, thereby driving the annular cutter 25 to move laterally, so that the annular cutter 25 can be brought close to the angle iron and cut the angle iron.

[0031] The angle iron material (such as carbon steel Q235, stainless steel 304, thickness 5-50mm), preferably, a mechanical protective cover is installed around the annular cutter 25 and connected by a hinge for easy maintenance.

[0032] The present application can be used in the field of metal processing technology, and can also be used in other fields applicable to the present application.

[0033] In another embodiment: Figure 1 Figure 2 、 Figure 7 、 Figure 8 and Figure 9A cutting device for producing angle irons, which is applied to the field of metal processing technology, comprises a protective mechanism including an equipment frame 26, on which a moving assembly and a spraying assembly are respectively provided. The moving assembly includes an active roller 27 rotatably connected to the equipment frame 26, a stepper motor 30 fixedly mounted on one side of the equipment frame 26, the output shaft of the stepper motor 30 extending into the equipment frame 26 and fixedly connected to one end of the active roller 27. Sliding holes 32 are provided on the inner walls on both sides of the equipment frame 26, and a contraction member is mounted in the sliding holes 32. The contraction member includes a sliding plate 33 slidably connected to the sliding holes 32, a driven roller 28 passes through the sliding plate 33 and is rotatably connected to the sliding plate 33, a locking screw 34 is rotatably connected to one side of the sliding plate 33, and a locking nut 35 is fixedly mounted on the outside of the equipment frame 26, one end of the locking screw 34 respectively passes through the inner wall of one side of the sliding hole 32 and the locking nut 35 and extends to one side of the locking nut 35, and the locking screw 34 is threadedly connected to the locking nut 35. The two retracting members are connected to the same driven roller 28, and the active roller 27 and the driven roller 28 are connected to the same conveyor belt 29 (preferably, limit baffles can be installed on both sides of the conveyor belt 29 to prevent the angle iron from slipping). A plurality of angle iron support bars 31 are fixedly installed on the conveyor belt 29 at equal intervals, and the angle iron support bars 31 are provided with triangular grooves for supporting the cut angle iron. A pad 36 is fixedly installed in the equipment frame 26 and passes through the conveyor belt 29, and the spray assembly is installed on the top of the pad 36. After the cut angle iron is dropped into the corresponding triangular groove, the locking screw 34 is rotated and driven by the threaded transmission of the locking nut 35, which drives the sliding plate 33 to move to the side away from the active roller 27, thereby tightening the conveyor belt 29. This prevents the conveyor belt 29 from slipping when the conveyor belt 29 is supported and driven. Then, the stepper motor 30 is started to drive the active roller 27 to rotate. At this time, with the support and cooperation of the driven roller 28, the conveyor belt 29 can be driven to move, thereby driving the angle iron to move, so that the protective coating can be sprayed on the cross-sections of both ends of the angle iron using the spraying assembly.

[0034] like Figure 9As shown, the spray assembly includes a delivery pump 39 fixedly mounted on the equipment frame 26. The suction end of the delivery pump 39 is fixedly connected to a connecting conduit 43, which is used to connect to an external pipeline for delivering protective coating. The output end of the delivery pump 39 is fixedly connected to a connection box 40. Delivery conduits 41 are fixedly mounted on the inner walls of both sides of the connection box 40. The top of the delivery conduit 41 extends above the equipment frame 26 and is fixedly connected to the top of the base plate 36. A nozzle 42 is fixedly mounted on the top of the delivery conduit 41. Two installation boxes 37 are symmetrically fixedly mounted on the top of the base plate 36, and electric heating racks 38 are fixedly mounted in the installation boxes 37. Then connect the connecting conduit 43 to the external pipe for conveying the protective coating, and then start the conveying pump 39 to convey the protective coating into the connecting box 40. After that, the protective coating can be sprayed out by the two nozzles 42 through the two conveying conduits 41. Therefore, when the cut angle iron is moved to the position corresponding to the two nozzles 42, the protective coating can be sprayed on the cross-sections at both ends of the angle iron. After spraying, the angle iron is kept moving, and the heat generated by the energized electric heating racks 38 in the mounting boxes 37 on both sides can be used to dry the two ends of the angle iron to form a protective coating. After the angle iron is cut, the problem of oxidation and rust on the cut cross-section can be avoided.

[0035] The present invention provides a cutting method, which is applied to the cutting equipment for producing angle iron as described above, comprising the following steps: S1. Place the required limit seat 17 in the support frame 13, and fit the No. II card plate 20 into the card hole 19. Then rotate the positioning screw 15. At this time, under the action of the thread transmission with the inner wall of one side of the support frame 13, the positioning screw 15 can be moved, which can drive the pressing plate 14 to move, so that the No. I card plate 16 is inserted into the card slot and fits with the card slot, so that the replaced limit seat 17 can be stably limited. S2. Pass the angle iron to be cut through the two mounting bases 3 and place the angle iron on the two driving wheels 4. Then, rotate the adjusting screw 11. Under the threaded transmission action of the adjusting nut 12, the connecting frame 10 can be driven downward, which can drive the clamping wheel 9 to move downward. The cross-section of the clamping wheel 9 is diamond-shaped, so it can be in close contact with the inner side of the angle iron, so that under the cooperation with the driving wheel 4, the angle iron can be stably clamped and limited. S3. Start the No. 1 drive motor 5 to drive one of the drive wheels 4 to rotate. Then, under the transmission action of the two synchronous wheels 6 and the synchronous belt 7, the other drive wheel 4 can be rotated synchronously. Therefore, the two driving wheels 4 that keep rotating can stably drive the angle iron to move, so that the angle iron passes through the positioning hole 18. The angle iron is wrapped by the limit seat 17 to prevent the angle iron from shaking when cutting. S4. After the angle iron is moved to the length required for cutting, the No. II drive motor 24 and the electric push rod 23 are started. When the No. II drive motor 24 rotates, it can drive the annular cutter 25 to rotate at high speed. When the electric push rod 23 is running, it can drive the moving base 22 to move, thereby driving the annular cutter 25 to move horizontally, so that the annular cutter 25 can be brought close to the angle iron and cut the angle iron; S5. The cut angle iron falls into the triangular groove on the angle iron support bar 31. Then, the stepping motor 30 is started to drive the active roller 27 to rotate. At this time, with the support and cooperation of the driven roller 28, the conveyor belt 29 can be driven to move, thereby driving the angle iron to move, so that the two ends of the angle iron move to the positions corresponding to the two nozzles 42. S6. Start the delivery pump 39 to deliver the protective coating into the connection box 40. After that, the protective coating is delivered through the two delivery pipes 41 and sprayed out from the two nozzles 42. Therefore, when the cut angle iron is moved to the position corresponding to the two nozzles 42, the protective coating can be sprayed on the cross-sections at both ends of the angle iron. After spraying, the angle iron is kept moving, and the heat generated by the powered electric heating racks 38 in the installation boxes 37 on both sides can be used to dry the ends of the angle iron, forming a protective coating. After the angle iron is cut, the problem of oxidation and rust on the cut cross-section can be avoided.
