Description

Technical Field

[0001] The present invention relates to the technical field of hot-rolled steel sawing processing, and particularly relates to a hot saw for processing hot-rolled steel sections. Background Art

[0002] During the production process of hot-rolled steel sections, the temperature is relatively high. When the steel rolling is completed, it is still in a red-hot state. At this time, the steel has good plasticity and small cutting resistance. Therefore, using a hot saw to cut it can greatly improve the cutting efficiency and finished product quality. The hot saw can quickly cut the hot steel sections to the required length, avoiding the energy consumption and deformation problems caused by reprocessing after cooling.

[0003] After the hot-rolled steel sections are cut by the hot saw, two cutting ends will be formed. Burrs will be formed at both cutting ends, and burrs will also be formed at the four edges of the cutting ends. In the prior art, most of the cut hot-rolled steel sections are transferred from the hot saw to a dedicated burr treatment device. However, during the transfer process, the burrs have cooled down, and the burrs quickly become hard and brittle after cooling, resulting in more difficult removal, longer time consumption, and lower efficiency when the subsequent burr treatment equipment processes the burrs. Summary of the Invention

[0004] The purpose of the present invention is to solve the problem that in the prior art, most of the cut hot-rolled steel sections are transferred from the hot saw to a dedicated burr treatment device. However, during the transfer process, the burrs have cooled down, and the burrs quickly become hard and brittle after cooling, resulting in more difficult removal, longer time consumption, and lower efficiency when the subsequent burr treatment equipment processes the burrs. A hot saw for processing hot-rolled steel sections is proposed.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions: A hot saw for processing hot-rolled steel sections, including a workbench, a speed reducer, and a hot saw blade. An installation platform is provided at the top of one end of the workbench. The speed reducer is provided on the top of the installation platform, and the output end of the speed reducer is connected to the rotating shaft of the hot saw blade; A feeding assembly is provided on one side surface of the workbench with respect to the installation platform. The feeding assembly includes a feeding cross plate, which is used to carry the hot-rolled steel sections to be cut and is slidably arranged on the top of the workbench through a T-shaped rail. The feeding cross plate transfers the hot-rolled steel sections to be cut between the loading position and the cutting position; A multi-sided chip scraping assembly is provided on the top of the feeding cross plate. The chip scraping frame in the multi-sided chip scraping assembly is sleeved on the outer wall of the hot-rolled steel sections to be cut. When the hot-rolled steel sections are cut to form two cutting ends, the chip scraping frame crosses the two cutting ends and contacts the edges of the two cutting ends.

[0006] Optionally, the multi-faceted chip scraping component includes a chip scraping frame, a driven rod, and a safety driving component. When the multi-faceted chip scraping component cuts the two cutting ends, the safety driving component prevents the feeding component from accidentally starting and moving to the cutting position, resulting in a collision between the multi-faceted chip scraping component and the hot saw blade.

[0007] Optionally, a fixing component is arranged on the top of the feeding cross plate. The fixing component includes a fixing cylinder, a pressing plate, and an inverted U-shaped frame. Right-angle rods are symmetrically and fixedly arranged on the top of the feeding cross plate. An inverted U-shaped frame is fixedly arranged between the two right-angle rods.

After passing through the transverse movement groove, the vertical rod is fixedly provided with a transverse movement block. The longitudinal width of the transverse movement block is greater than the longitudinal width of the transverse movement groove.

[0008] Optionally, a receiving groove is formed on the top of the feeding cross plate. Auxiliary frames are symmetrically and fixedly arranged in the receiving groove. A fixing cylinder is fixedly arranged on the top of the right-angle rod. The output end of the fixing cylinder is fixedly provided with a pressing plate.

[0009] Optionally, the safety driving component includes a driven rod, a driving block, a counterweight column, and a chip scraping screw rod. Both ends of the chip scraping screw rod are rotatably connected to the top of a compensation seat. The compensation seat is fixedly arranged on the top of a triangular plate. The triangular plate is fixedly arranged on the side of the workbench. One end of the chip scraping screw rod is fixedly connected to the output end of a chip scraping motor.

[0010] Optionally, a driving block is screwed onto the outer wall of the chip scraping screw rod. An insertion groove is formed on the top of the driving block. First inclined surfaces are formed on both side surfaces of the insertion groove on the top of the driving block. One end of the side surface of the chip scraping frame is rotatably connected to one end of the driven rod. A second inclined surface is formed on the side surface of the driving block close to the driven rod.

[0011] Optionally, a counterweight block is fixedly arranged at the bottom of the driven rod. An arc surface is formed at the bottom of one end of the driven rod close to the second inclined surface. One end of the driven rod provided with the arc surface is inserted into the insertion groove.

[0012] Optionally, the top of the counterweight column is fixedly connected to one end of a pulling rope. The other end of the pulling rope is placed inside the wheel groove of a guide wheel and then fixedly connected to the side surface of the transverse movement block. The guide wheel is rotatably connected to the side surface of a mounting seat. The mounting seat is fixedly connected to the side surface of the inverted U-shaped frame.

[0013] Optionally, a microswitch is fixedly arranged on the side surface of the triangular plate. The microswitch is connected to the control circuit of the chip scraping motor.

[0014] Optionally, a T-shaped rail is movably inserted at the bottom of the feeding cross plate, and the T-shaped rail is fixedly connected to the top of the workbench. A vertical seat is fixedly arranged at the edge position of the top of the workbench, and a feeding motor is fixedly arranged on the side of the vertical seat. A feeding screw rod is fixedly arranged at the output end of the feeding motor, and the feeding screw rod is threadedly screwed into the side of the feeding cross plate.

[0015] Optionally, a folding rod is fixedly arranged on the top of the mounting table, and a protective cover is fixedly arranged at the other end of the folding rod. The side of the hot saw blade is exposed from the side of the protective cover.

[0016] Compared with the prior art, the present invention has the following advantages: 1. The main structure of the present invention includes a hot saw blade, a workbench and a feeding assembly. A multi-faceted shaving assembly is arranged on the side of the workbench. After the feeding cross plate in the feeding assembly finishes cutting the hot-rolled steel section to be cut and retreats to the loading position, the multi-faceted shaving assembly will cross the two cutting ends and simultaneously scrape the burrs generated at the four ridge lines of the two cutting ends. After hot saw cutting, the cutting surface and the burr area are still in a high-temperature semi-softened state. At this time, the multi-faceted shaving assembly intervenes, and the burrs can be directly scraped using the state where the burrs have not been completely hardened. Compared with scraping after cooling, the scraping resistance is small, the efficiency is high, and the wear of the equipment is small. The multi-faceted shaving assembly covers the cutting end faces of two sections of hot-rolled steel sections, and the burr treatment at both ends can be completed simultaneously with one round-trip movement, synchronously processing the two ports, saving time.

[0017] 2. The core component of the multi-faceted shaving assembly provided by the present invention is also provided with a safety drive assembly. The safety drive assembly can only provide a power source for the multi-faceted shaving assembly to drive the displacement of the multi-faceted shaving assembly when the multi-faceted shaving assembly performs a shaving action at the loading position. When the loading assembly accidentally starts and displaces to the cutting position, it automatically separates from the multi-faceted shaving assembly, and the multi-faceted shaving assembly cannot displace, avoiding the collision between the multi-faceted shaving assembly and the hot saw blade, ensuring the safe operation of the equipment, reducing the damage risk, and improving the stability and safety of the overall system.

[0018] 3. The safety drive assembly of the present invention has a dual safety structure. One safety structure is a pure mechanical structure, which relies on physical limit to achieve passive disconnection, and has the advantage of reliable disconnection without power supply, and can block the movement path of the multi-faceted shaving assembly in the first time in case of emergency; the other is an electrical structure based on a micro switch, which can sense the position state of the loading assembly in real time and automatically cut off the drive power supply through the control circuit to achieve intelligent interlocking protection. The dual structures are redundant with each other, which not only ensures the basic safety of the system in case of power failure or failure, but also improves the overall response sensitivity and control accuracy, and greatly enhances the operation reliability of the equipment and the safety of personnel operation.

[0019] 4. The safety drive component of the present invention has a self-resetting function. When the feeding component accidentally starts to move to the cutting position, it automatically separates from the multi-faceted chip scraping component. After the multi-faceted chip scraping component cannot move, when the pure mechanical structure of the safety drive component needs to be re-docked with the multi-faceted chip scraping component, the motor in the safety drive component and the motor of the feeding component only need to drive the drive block of the safety drive component and the feeding cross plate to return to the initial feeding position. Through the first inclined surface and the second inclined surface provided on the drive block and the driven rod provided on the side of the multi-faceted chip scraping component, the pure mechanical structure of the safety drive component can be automatically docked with the multi-faceted chip scraping component. Once the traditional structure is separated or abnormally disconnected, it usually requires manual alignment and reconnection, which is time-consuming and laborious and has the risk of misoperation. Through the guiding cooperation between the first inclined surface and the second inclined surface on the drive block and the driven rod on the side of the multi-faceted chip scraping component, the present invention realizes automatic reset docking while restoring to the initial feeding position, greatly improving the automation operation level and intelligence degree of the equipment. During the restoration process, there is no need for personnel to approach the equipment movement area at all, effectively ensuring the personal safety of the operators and meeting the requirements of modern industry for high-safety-level equipment.

Detailed implementation manner

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0032] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, 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 should not be construed as a limitation of the present invention.

[0033] Referring to Figures 1-10 , a hot sawing machine for hot-rolling section steel processing, including a workbench 2, a reducer 4, and a hot saw blade 7. A reducer 4 is arranged on the top of a mounting table 3. The output end of the reducer 4 is connected to the rotating shaft of the hot saw blade 7, and the input end of the reducer 4 is fixedly connected to the output end of a driving motor 9. The housing of the driving motor 9 is fixedly arranged on the side surface of the housing of the reducer 4. The reducer 4 reduces the rotational speed of the driving motor 9 and increases the torque transmitted from the driving motor 9 to the hot saw blade 7. The diameter of the hot saw blade 7 is set to be relatively large. The large-diameter hot saw blade 7 has a longer radial cutting depth during the cutting process, can meet the needs of cutting large-section section steel during the hot-rolling process, improves the versatility and processing ability of the hot sawing machine. By converting the high-speed and low-torque output of the motor into a low-speed and high-torque transmission through the reducer 4, the anti-jamming ability of the hot saw blade 7 during the high-temperature and high-resistance cutting process can be effectively improved, so that it can still maintain stable cutting under complex working conditions such as high-temperature softening, adhesion, and oxidation scale adhesion of section steel, and reduce the phenomena of saw blade slipping, tooth skipping, and jamming.

[0034] The workbench 2 is provided with a feeding assembly on one side of the mounting platform 3, and the feeding assembly includes a feeding horizontal plate 11, and a fixing assembly is provided on the top of the feeding horizontal plate 11, and the fixing assembly includes a fixing cylinder 13, a holding plate 131, and an inverted U frame 14. A right-angle rod 15 is symmetrically fixedly provided on the top of the feeding horizontal plate 11, and a receiving groove 110 is opened on the top of the feeding horizontal plate 11, and an auxiliary frame 12 is symmetrically fixedly provided in the receiving groove 110, and a fixing cylinder 13 is fixedly provided on the top of the right-angle rod 15. The fixing cylinder 13 A holding plate 131 is fixedly provided at the output end. When the fixed cylinder 13 is extended, it is pressed against the top of the hot-rolled steel to be cut by the holding plate 131 to prevent the hot-rolled steel to be cut from shifting when the heated saw blade 7 is cutting. A folding rod 8 is fixedly provided on the top of the mounting table 3. A protective cover 81 is fixedly provided at the other end of the folding rod 8. The side of the hot saw blade 7 is exposed from the side of the protective cover 81. The protective cover 81 protects the hot saw blade 7. In order to cool the hot saw blade 7, the protective cover 81 also needs to be connected to external cooling water.

[0035] An inverted U frame 14 is fixedly installed between the two right-angle rods 15, and a transverse groove 141 is opened on the top of the inverted U frame 14. A vertical rod 16 is fixedly installed on the top of the scraper frame 17. After the vertical rod 16 passes through the transverse groove 141, a transverse block 161 is fixedly installed. The longitudinal width of the transverse block 161 is greater than the longitudinal width of the transverse groove 141. The setting of the transverse block 161 and the vertical rod 16 assists the scraper frame 17 to move stably in the horizontal direction.

[0036] The inverted U-frame 14 includes a vertical portion and a horizontal portion, and the transverse movement groove 141 is specifically arranged at the top of the horizontal portion. The horizontal portion of the inverted U-frame 14 provides a path for the lateral movement of the scraper frame 17. Vertical portions are fixedly arranged at the bottom of both ends of the horizontal portion of the inverted U-frame 14. The vertical portion of the inverted U-frame 14 is fixedly arranged on the top of the feeding cross plate 11, and the height of the vertical portion of the inverted U-frame 14 is set sufficient to avoid the horizontal portion of the inverted U-frame 14 from colliding with the top of the hot saw blade 7 when the inverted U-frame 14 moves to the side of the hot saw blade 7. In addition, the feeding cross plate 11 is provided with a cutting groove 10 in the longitudinal displacement path of the hot saw blade 7.

[0037] The feeding cross plate 11 is used to carry the hot-rolled steel to be cut, and is slidably arranged on the top of the workbench 2 through the T-rail 1. The feeding cross plate 11 transfers the hot-rolled steel to be cut between the loading position and the cutting position. A multi-faceted scraper assembly is arranged on the top of the feeding cross plate 11. The scraper frame 17 in the multi-faceted scraper assembly is sleeved on the outer wall of the hot-rolled steel to be cut. When the hot-rolled steel is cut and two cutting ends are formed, the scraper frame 17 passes over the two cutting ends and contacts the edges of the two cutting ends. The multi-faceted scraper assembly includes a scraper frame 17, a driven rod 18, and a safety drive assembly. The safety drive assembly prevents the feeding assembly from accidentally starting and moving to the cutting position when the multi-faceted scraper assembly cuts the two cutting ends, causing the multi-faceted scraper assembly to collide with the hot saw blade 7.

[0038] The safety drive assembly includes a driven rod 18, a drive block 22, a counterweight column 29, and a chip scraping screw 19. Both ends of the chip scraping screw 19 are rotatably connected to the top of a compensation seat 200. The compensation seat 200 is fixedly arranged on the top of a triangular plate 20. The triangular plate 20 is fixedly arranged on the side of a workbench 2. One end of the chip scraping screw 19 is fixedly connected to the output end of a chip scraping motor 23. A drive block 22 is screwed onto the outer wall of the chip scraping screw 19. An insertion slot 25 is formed at the top of the drive block 22. First inclined surfaces 24 are formed on both side surfaces of the insertion slot 25 at the top of the drive block 22. One side of the chip scraping frame 17 is rotatably connected to one end of the driven rod 18. A second inclined surface 221 is formed on one side of the drive block 22 close to the driven rod 18. Due to the arrangement of the first inclined surface 24, when one end of the driven rod 18 gradually approaches the side surface of the drive block 22, one end of the driven rod 18 will cross the first inclined surface 24 and enter the inside of the insertion slot 25.

[0039] A counterweight block 181 is fixedly arranged at the bottom of the driven rod 18. An arc surface 182 is formed at the bottom of one end of the driven rod 18 close to the second inclined surface 221. One end of the driven rod 18 provided with the arc surface 182 is inserted into the inside of the insertion slot 25. The arrangement of the arc surface 182 reduces the wear of one end of the driven rod 18 when one end of the driven rod 18 gradually approaches the side surface of the drive block 22, and one end of the driven rod 18 will cross the first inclined surface 24 and enter the inside of the insertion slot 25. The arrangement of the counterweight block 181 enables one end of the driven rod 18 to automatically fall into the inside of the insertion slot 25 due to gravity when one end of the driven rod 18 crosses the first inclined surface 24. When one end of the driven rod 18 disengages from the insertion slot 25, it will naturally rest on the top of the feeding cross plate 11.

[0040] The top of the counterweight column 29 is fixedly connected to one end of a pulling rope 26. The other end of the pulling rope 26 is placed inside the pulley groove of a guide pulley 28 and then fixedly connected to the side surface of a cross - moving block 161. The guide pulley 28 is rotatably connected to the side surface of a mounting seat 27. The mounting seat 27 is fixedly connected to the side surface of an inverted U - shaped frame 14. When the feeding cross plate 11 is at the loading station, the chip scraping frame 17 is at the extreme position at one end of a cross - moving groove 141, and the counterweight column 29 is at the lowest horizontal position. When the chip scraping motor 23 drives the drive block 22 to move through the chip scraping screw 19, the drive block 22 drives the chip scraping frame 17 to cross two cutting ends and contact the two cutting end ridges to scrape off burrs. During this process, the cross - moving block 161 drives the counterweight column 29 to move upward through the pulling rope 26. When one end of the driven rod 18 moves out of the insertion slot 25, at this time, the counterweight column 29 moves downward due to gravity, and drives the chip scraping frame 17 to quickly fall back to the left - most position through the pulling rope 26 and the cross - moving block 161, avoiding the collision between the chip scraping frame 17 and the hot saw blade 7.

[0041] A micro - switch 21 is fixedly arranged on the side surface of the triangular plate 20. The micro - switch 21 is connected to the control circuit of the chip scraping motor 23. When the feeding cross plate 11 is in the loading position, the micro - switch 21 is pressed, and only then can the chip scraping motor 23 be powered on and rotate.

[0042] The bottom of the feeding cross plate 11 is movably inserted with a T-shaped rail 1. The T-shaped rail 1 is fixedly connected to the top of the workbench 2. A vertical seat 6 is fixedly arranged at the edge position of the top of the workbench 2. A feeding motor 5 is fixedly arranged on the side of the vertical seat 6. The output end of the feeding motor 5 is fixedly provided with a feeding screw rod 51, and the feeding screw rod 51 is screwed into the side of the feeding cross plate 11.

[0043] The specific implementation steps and principles of the present invention are as follows: When the feeding cross plate 11 is at the loading station, at this time, one end of the driven rod 18 is inserted into the insertion groove 25, the counterweight column 29 is at the lowest horizontal position, the transverse movement block 161 is at one extreme position of the transverse movement groove 141, and the chip scraping frame 17 is at one extreme position of the transverse movement groove 141. The worker inserts the hot-rolled section steel to be cut into the accommodation groove 110. The chip scraping frame 17 and the auxiliary frame 12 are both sleeved on the outer wall of the hot-rolled section steel. Finally, two fixed cylinders 13 are started. The fixed cylinders 13 extend to drive the pressing plate 131 to move downward to fix the hot-rolled section steel. The driving motor 9 and the feeding motor 5 are started. The feeding motor 5 drives the hot-rolled section steel on the feeding cross plate 11 to move to the side of the hot saw blade 7 through the feeding screw rod 51, and the hot saw blade 7 cuts the hot-rolled section steel to form two cutting ends.

[0044] After the cutting is completed, the feeding motor 5 drives the hot-rolled section steel on the feeding cross plate 11 to move back to the loading position through the feeding screw rod 51. At this time, the microswitch 21 is triggered. One end of the driven rod 18 crosses the second inclined surface 221 and finally enters the insertion groove 25. At this time, the chip scraping motor 23 is started. The chip scraping motor 23 drives the driving block 22 to move through the chip scraping screw rod 19. The driving block 22 drives the chip scraping frame 17 to cross the two cutting ends and contact the ridge lines of the two cutting ends through the driven rod 18 to scrape off the burrs. During this process, the transverse movement block 161 drives the counterweight column 29 to move upward through the pulling rope 26. Suppose during this process, the feeding motor 5 is accidentally started and the feeding cross plate 11 moves towards the hot saw blade 7. At this time, the microswitch 21 is no longer triggered, the chip scraping motor 23 cannot continue to rotate, and one end of the driven rod 18 moves out of the insertion groove 25. At this time, the counterweight column 29 moves downward due to gravity and drives the chip scraping frame 17 to quickly fall back to the leftmost position through the pulling rope 26 and the transverse movement block 161.

[0045] The above is only the preferred specific implementation manner 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, makes equivalent replacements or changes, and all should be covered within the protection scope of the present invention.
