Description

Technical Field

[0001] The invention relates to the technical field of hot-rolled steel sawing processing, in particular to a hot sawing machine for processing hot-rolled steel sections. Background Art

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

[0003] After being cut by a hot saw, hot-rolled steel sections will form two cut ends, both of which will form burrs, and burrs will be formed at the four edges of the cut ends. In the existing technology, the cut hot-rolled steel sections will mostly be transferred from the hot saw to a dedicated burr processing equipment. However, during the transfer process, the burrs have cooled down, and the burrs quickly become hard and brittle after cooling, resulting in subsequent burr processing equipment. Subsequent grinding or scraping will be more difficult to remove the burrs, taking longer time, and having lower efficiency. Summary of the Invention

[0004] The purpose of the present invention is to solve the problem that in the prior art, most of the hot-rolled steel sections are transferred from the hot saw machine to a dedicated burr processing equipment after cutting. However, during the transfer process, the burrs have cooled down and the burrs quickly become hard and brittle after cooling, which makes it more difficult to remove the burrs by subsequent grinding or scraping when the subsequent burr processing equipment is used, which takes longer time and is less efficient. A hot saw machine for processing hot-rolled steel sections is proposed.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

A mounting platform is provided on the top of one end of the workbench, a reducer is provided on the top of the mounting platform, and an output end of the reducer is connected to a rotating shaft of the hot saw blade.

[0007] The workbench is provided with a feeding assembly on one side of the mounting platform, and the feeding assembly includes a feeding cross plate, which is used to carry the hot-rolled steel to be cut and is slidably arranged on the top of the workbench through a T-rail.

[0013] Optionally, a drive block is screwed into the outer wall of the scraping screw, an insertion groove is provided on the top of the drive block, a first inclined surface is provided on both sides of the insertion groove on the top of the drive block, the side of the scraping frame is rotatably connected to one end of the driven rod, and a second inclined surface is provided on the side of the drive block close to the driven rod.

[0014] Optionally, a counterweight is fixedly provided at the bottom of the driven rod, an arcuate surface is provided at the bottom of one end of the driven rod close to the second inclined surface, and the end of the driven rod provided with the arcuate surface is inserted into the insertion slot.

[0015] Optionally, the top of the counterweight column is fixedly connected to one end of the pulling rope, and the other end of the pulling rope is overlapped inside the guide wheel groove and then fixedly connected to the side of the transverse block. The guide wheel is rotatably connected to the side of the mounting seat, and the mounting seat is fixedly connected to the side of the inverted U frame.

[0016] Optionally, a micro switch is fixedly provided on the side surface of the triangular plate, and the micro switch is connected to the control circuit of the scraper motor.

[0017] Optionally, a T-rail is movably inserted into the bottom of the feeding cross plate, and the T-rail is fixedly connected to the top of the workbench. A vertical seat is fixedly provided at the edge of the top of the workbench, and a feeding motor is fixedly provided on the side of the vertical seat. A feeding screw is fixedly provided at the output end of the feeding motor, and the feeding screw is threaded into the side of the feeding cross plate.

[0018] Optionally, a folding rod is fixedly provided on the top of the mounting platform, a protective cover is fixedly provided on the other end of the folding rod, and the side surface of the hot saw blade is exposed from the side surface of the protective cover.

[0019] Compared with the prior art, the present invention has the following advantages:

[0020] 1. The main structure of the present invention includes a hot saw blade, a workbench and a feeding assembly, and a multi-faceted scraper assembly is provided on the side of the workbench. When the feeding cross plate in the feeding assembly completes cutting the hot-rolled steel to be cut and returns to the loading position, the multi-faceted scraper assembly will pass over the two cutting ends and scrape off the burrs generated at the four edges of the two cutting ends at the same time. After the hot saw cutting, the cutting surface and the burr area are still in a high-temperature semi-softened state. The multi-faceted scraper assembly intervenes at this time and can directly scrape off the burrs in the state that they have not yet completely hardened. Compared with scraping after cooling, the scraping resistance is small, the efficiency is high, and the wear on the equipment is small. The multi-faceted scraper assembly covers the cutting end faces of the two sections of hot-rolled steel. One reciprocating action can complete the burr processing at both ends at the same time, and the two sections of the port are processed synchronously, saving time.

[0021] 2. The core component of the multi-sided scraper assembly provided in the present invention is also provided with a safety drive component. The safety drive component can only provide a power source for the multi-sided scraper assembly when the multi-sided scraper assembly is performing a scraping action at the loading position, thereby driving the multi-sided scraper assembly to move. When the loading component is accidentally started and moved to the cutting position, it automatically separates from the multi-sided scraper assembly, and the multi-sided scraper assembly cannot move, thereby avoiding collision between the multi-sided scraper assembly and the hot saw blade, ensuring safe operation of the equipment, reducing the risk of damage, and improving the stability and safety of the overall system.

[0022] 3. The safety drive assembly of the present invention has a dual safety structure. One safety structure is a purely mechanical structure, which relies on physical limits to achieve passive disengagement. It has the advantage of being able to reliably disconnect without power supply, and can block the movement path of the multi-faceted scraper assembly in the first time in an emergency; the other is an electrical structure based on a microswitch, which can sense the position status of the feeding assembly in real time, automatically cut off the driving power supply through the control circuit, and realize intelligent interlocking protection. The dual structures are redundant with each other, which not only ensures that the system still has basic safety in the event of power outage or failure, but also improves the overall response sensitivity and control accuracy, greatly enhancing the operating reliability of the equipment and the safety of personnel operation.

[0023] 4. The safety drive assembly of the present invention has a self-resetting function. When the loading assembly is accidentally started and displaced to the cutting position, it automatically separates from the multi-sided scraper assembly. After the multi-sided scraper assembly cannot be displaced, when the purely mechanical structure of the safety drive assembly needs to be re-docked with the multi-sided scraper assembly, the motor in the safety drive assembly and the motor of the loading assembly only need to drive the drive block of the safety drive assembly and the loading cross plate to return to the initial loading position. Through the first bevel and the second bevel provided on the drive block and the follower rod provided on the side of the multi-sided scraper assembly, the purely mechanical structure of the safety drive assembly can be automatically docked with the multi-sided scraper assembly. Once the traditional structure is detached or abnormally disconnected, it usually requires manual alignment and reconnection, which is time-consuming and labor-intensive and has the risk of misoperation. The present invention achieves automatic resetting and docking while restoring the initial loading position through the guidance and cooperation between the first bevel and the second bevel on the drive block and the follower rod on the side of the multi-sided scraper assembly, thereby greatly improving the automation operation level and intelligence level of the equipment. During the recovery process, there is no need for personnel to approach the movement area of ​​the equipment, effectively ensuring the personal safety of the operator, and meeting the requirements of modern industry for high-safety equipment.

[0038] The workbench 2 is provided with a feeding assembly on one side of the mounting table 3. The feeding assembly includes a feeding horizontal plate 11. A fixing assembly is provided on the top of the feeding horizontal plate 11. 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 fixed on the top of the feeding horizontal plate 11. A receiving groove 110 is provided on the top of the feeding horizontal plate 11. An auxiliary frame 12 is symmetrically fixed in the receiving groove 110. A fixing cylinder 13 is fixed on the top of the right-angle rod 15. The fixing cylinder 13 is fixed on the top of the fixing cylinder 13. A holding plate 131 is fixedly provided at the output end. When the fixed cylinder 13 is extended, it is supported by the holding plate 131 to the top of the hot-rolled steel to be cut, so as 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, and 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, and in order to cool the hot saw blade 7, the protective cover 81 also needs to be connected to external cooling water.

[0039] An inverted U-frame 14 is fixed between the two right-angle rods 15, and a transverse slot 141 is provided at the top of the inverted U-frame 14. A vertical rod 16 is fixed to the top of the scraper frame 17. After the vertical rod 16 passes through the transverse slot 141, a transverse block 161 is fixed thereto. The longitudinal width of the transverse block 161 is greater than the longitudinal width of the transverse slot 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.

[0040] The inverted U-frame 14 includes a vertical part and a horizontal part. The transverse movement groove 141 is specifically arranged at the top of the horizontal part. The horizontal part of the inverted U-frame 14 provides a path for the transverse movement of the scraper frame 17. Vertical parts are fixedly provided at the bottom of both ends of the horizontal part of the inverted U-frame 14. The vertical part of the inverted U-frame 14 is fixedly provided at the top of the feeding cross plate 11, and the height of the vertical part of the inverted U-frame 14 is set sufficient to avoid the horizontal part of the inverted U-frame 14 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.

[0041] The feeding cross plate 11 is used to carry the hot-rolled steel to be cut, and is slidably set 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 provided 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 ridges 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.

[0042] The safety drive assembly includes a driven rod 18, a driving block 22, a counterweight column 29 and a scraper screw 19. Both ends of the scraper screw 19 are rotatably connected to the top of the compensation seat 200. The compensation seat 200 is fixedly set on the top of the triangle plate 20. The triangle plate 20 is fixedly set on the side of the workbench 2. One end of the scraper screw 19 is fixedly connected to the output end of the scraper motor 23. The outer wall of the scraper screw 19 is threaded with a driving block 22. An insertion groove 25 is provided at the top of the driving block 22. A first inclined surface 24 is provided on both sides of the insertion groove 25 at the top of the driving block 22. The side of the scraper frame 17 is rotatably connected to one end of the driven rod 18. A second inclined surface 221 is provided on the side of the driven rod 18 near the driving block 22. The setting of the first inclined surface 24 is such that when one end of the driven rod 18 gradually approaches the side of the driving block 22, one end of the driven rod 18 will pass over the first inclined surface 24 and enter the inside of the insertion groove 25.

[0043] A counterweight 181 is fixedly provided at the bottom of the driven rod 18, and an arcuate surface 182 is provided at the bottom of one end of the driven rod 18 near the second inclined surface 221. The end of the driven rod 18 provided with the arcuate surface 182 is inserted into the insertion groove 25. The setting of the arcuate 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 of the driving block 22 and one end of the driven rod 18 passes over the first inclined surface 24 and enters the insertion groove 25. The setting of the counterweight 181 makes it possible for one end of the driven rod 18 to automatically fall into the insertion groove 25 due to gravity when the one end of the driven rod 18 passes over the first inclined surface 24. When the one end of the driven rod 18 detaches from the insertion groove 25, it will naturally overlap with the top of the feeding cross plate 11.

[0044] The top of the counterweight column 29 is fixedly connected to one end of the pulling rope 26, and the other end of the pulling rope 26 is connected to the inside of the wheel groove of the guide wheel 28 and fixedly connected to the side of the transverse block 161. The guide wheel 28 is rotatably connected to the side of the mounting seat 27, and the mounting seat 27 is fixedly connected to the side of the inverted U frame 14. When the feeding cross plate 11 is in the loading station, the scraper frame 17 is in the extreme position at one end of the transverse groove 141, and the counterweight column 29 is in the lowest horizontal position. When the scraper motor 23 drives the drive through the scraper screw 19, The movable block 22 moves, and the driving block 22 drives the scraper frame 17 through the driven rod 18 to cross the two cutting ends and contact the two cutting end edges to scrape off burrs. In this process, the transverse 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, the counterweight column 29 moves downward due to gravity, and drives the scraper frame 17 to quickly fall back to the leftmost position through the pulling rope 26 and the transverse block 161 to avoid collision between the scraper frame 17 and the hot saw blade 7.

[0045] A micro switch 21 is fixedly provided on the side of the triangle plate 20. The micro switch 21 is connected to the control circuit of the scraper motor 23. When the feeding cross plate 11 is in the loading position, the micro switch 21 is pressed, and the scraper motor 23 can be powered and rotated.

[0046] A T-rail 1 is movably inserted into the bottom of the feeding horizontal plate 11, and the T-rail 1 is fixedly connected to the top of the workbench 2. A vertical seat 6 is fixedly set at the top edge of the workbench 2, and a feeding motor 5 is fixedly set on the side of the vertical seat 6. A feeding screw 51 is fixedly set at the output end of the feeding motor 5, and the feeding screw 51 is threaded into the side of the feeding horizontal plate 11.

[0047] The specific implementation steps and principles of the present invention are as follows:

[0048] When the feeding cross plate 11 is in the loading station, one end of the driven rod 18 is inserted into the insertion slot 25, the counterweight column 29 is in the lowest horizontal position, the transverse block 161 is at the extreme position on one side of the transverse slot 141, and the scraper frame 17 is at the extreme position at one end of the transverse slot 141. The worker inserts the hot-rolled steel to be cut into the accommodating slot 110, and the scraper frame 17 and the auxiliary frame 12 are both sleeved on the outer wall of the hot-rolled steel. Finally, the two fixed cylinders 13 are started, and the fixed cylinder 13 extends to drive the holding plate 131 to move downward to fix the hot-rolled steel. The drive motor 9 and the feeding motor 5 are started, and the feeding motor 5 drives the hot-rolled steel on the feeding cross plate 11 to move to the side of the hot saw blade 7 through the feeding screw 51. The hot saw blade 7 cuts the hot-rolled steel to form two cutting ends.

[0049] After the cutting is completed, the feeding motor 5 drives the hot-rolled steel on the feeding cross plate 11 to move back to the loading position through the feeding screw 51. At this time, the micro switch 21 is triggered, and one end of the driven rod 18 passes over the second inclined surface 221 and finally enters the insertion groove 25. At this time, the scraping motor 23 drives the driving block 22 to move through the scraping screw 19. The driving block 22 drives the scraping frame 17 through the driven rod 18 to pass over the two cutting ends and contact the two cutting end ridges to scrape off the burrs. In this process, the transverse moving block 161 drives the counterweight column 29 to move upward through the pulling rope 26.

[0050] If during this process, the feeding motor 5 is accidentally started and the feeding cross plate 11 moves toward the hot saw blade 7, the micro switch 21 is no longer triggered, the scraper motor 23 cannot continue to rotate, and 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 scraper frame 17 to quickly return to the leftmost position through the pulling rope 26 and the transverse block 161.

[0051] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
