Abstract
Description
Technical Field
[0001] This invention relates to the field of wheel processing technology, and in particular to a bar cutting device for wheel production. Background Technology
[0002] As a key load-bearing and moving component of the train's running gear, the performance of high-speed train wheels directly affects the train's operational safety, stability, and service life. High-speed train wheels are typically manufactured from high-performance special alloy steel bars (such as CL60, ER8, and ER9) through multiple processes including forging, rolling, heat treatment, and machining. In the initial stage of wheel manufacturing, long alloy steel bars need to be cut to a fixed length according to the specifications of the wheel blank. The processing quality and efficiency of this step have a fundamental impact on the cost control, material utilization rate, and processing accuracy of subsequent processes in the entire wheel production. The cut bars are then transported to a ring-shaped heating furnace for calcination and heating via a crane mechanism and a robotic arm.
[0003] Currently, common cutting methods in wheel bar cutting mainly include flame cutting, sawing (such as circular saws and band saws), and some CNC shearing equipment. Flame cutting equipment has low investment and strong adaptability, but its large heat-affected zone can easily lead to changes in the metallographic structure of the cut, the formation of a hardened layer and microcracks. At the same time, the cut surface is rough and has poor precision, requiring a large machining allowance, which not only increases material waste but also brings additional burden to subsequent wheel forming and machining. Traditional mechanical sawing (especially friction saws) has relatively improved cut surface quality, but it suffers from slow cutting speed, high saw blade wear, high energy consumption, and serious noise and dust pollution, making it difficult to meet the requirements of high efficiency, material saving, and environmental protection in modern wheel production lines. Currently, circular saws are used to cut wheel bar stock. Furthermore, carbide saw blades are required for cutting wheel bar stock, and cutting fluid is not used during the process. Wheel steel has extremely high hardness after quenching, while ordinary tool steel softens and anneals at high temperatures. Carbide, however, maintains its hardness above 850℃, ensuring cutting efficiency and precision. Moreover, this dry cutting method in train wheel processing relies solely on air cooling to dissipate heat from the saw blade, meeting both environmental and cost requirements while also being suitable for the characteristics of high-hardness materials, making it the most practical choice currently available.
[0004] In existing technologies, most air-cooling mechanisms use multiple jet nozzles to provide fixed-point airflow cooling to the saw teeth of the cutting saw blade. As the cutting feed rate increases, the temperature of most surfaces of the cutting saw blade also rises. The lack of cooling mechanisms in these areas leads to a shorter service life for the cutting saw blade. Furthermore, in existing technologies, after the wheel bar is cut, the circumference of the wheel bar will have a lot of impurities and rust due to prolonged storage. Placing the cut wheel bar directly into the annular heating furnace will affect the calcination effect of the annular heating furnace. Summary of the Invention

[0016] In summary, the present invention has the following beneficial effects: 1. In this invention, during the cutting process of the wheel bar, the cutting saw blade is divided into two operating states: a waiting state (hereinafter referred to as the idle state) and a cutting state. The operating speed of the rotating spindle in the waiting state is less than that in the cutting state, and the operating speed of the rotating spindle in the cutting state will increase with the increase of the cutting feed. In the idling state, the rotating spindle will generate centrifugal force during rotation, causing the push block to move outward. At this time, spring two will pull the push block, spring one will pull the sliding plate, and the distance between the sliding plates on both sides changes little. During the cutting process, the increased speed of the rotating spindle generates a stronger centrifugal force, causing the pusher block to move further outward. As the pusher block moves outward again, the sliding plates on both sides move closer together, narrowing the air duct between them. This narrowing of the air duct increases the exhaust air velocity, which can better remove the heat generated by the cutting saw blade and teeth during the cutting process. The exhaust cooling air will also evenly cover the cutting saw blade, thus better dissipating heat and extending its service life. Furthermore, the exhaust cooling air can dissipate heat at the cutting position of the wheel bar and blow away cutting debris. 2. In this invention, the movement of the wheel bar causes the toothed ring to rotate the steel brush, thereby removing rust and impurities from the circumferential surface of the wheel bar. Furthermore, the two steel brushes rotate in opposite directions, which can better clean the circumferential surface of the wheel bar. This reduces the impact of external impurities on the ring heating furnace when the cut wheel bar enters the subsequent annular heating furnace for heating and calcination, and improves the heating and calcination effect of the cut wheel bar. 3. In this invention, the impurities removed by brushing will detach from the circumferential surface of the wheel bar. Some of the detached impurities and dust will fall back onto the circumferential surface of the wheel bar. When the wheel bar passes the cutting saw blade, the cutting saw blade is in an idling state. The adhering impurities will be blown off by the cooling air discharged from the air outlet ring, thereby improving the cleaning effect on the wheel bar. 4. In this invention, during the cutting process, some of the metal cutting chips will fall onto the surface of the push rail and the conveyor belt. Some of the chips on the inclined surface of the push rail will slide onto the conveyor belt. As the wheel bar moves, another part of the chips will fall onto the surface of the conveyor belt. Then, the second motor is started, causing the connecting shaft to drive the conveyor belt to move. The conveyor belt carries away most of the metal cutting chips, preventing them from accumulating on the conveyor frame. Attached Figure Description

[0019] The principles and spirit of the present invention will be explained in detail below with reference to several representative embodiments.
[0020] Please see Figure 1-19 The present invention will now be described in detail with reference to the accompanying drawings and embodiments: like Figure 1 and 5 As shown in Figure 7, a rod cutting device for wheel production includes a feeding frame 1 for transporting wheel rods 8 to be cut and a conveying frame 6 for transporting wheel rods 8 after cutting. The conveying frame 6 is located on the right side of the feeding frame 1, and rod fixing frames 3 and rod cutting frames 4 are respectively provided on the front and rear sides of the feeding frame 1 and the conveying frame 6. The feeding rack 1 is equipped with a cleaning mechanism 5 for processing the circumferential surface of the wheel bar 8. The cleaning mechanism 5 can remove impurities and rust from the circumferential surface of the wheel bar 8, so that when the cut wheel bar 8 enters the subsequent annular heating furnace for heating and calcination, the external impurities it brings will affect the use effect of the annular heating furnace, and the heating and calcination effect of the cut wheel bar 8 will be improved. The cutting frame 4 is equipped with a cutting mechanism 7 for segmenting the wheel bar 8 and symmetrically arranged cutting cylinders 41 for driving the cutting mechanism 7. The fixing frame 3 is symmetrically equipped with clamping cylinders 32 for limiting and fixing the wheel bar 8 to be cut; The cutting mechanism 7 includes a support frame 71 that slides with the cutting frame 4. A cutting motor 73 is installed inside the support frame 71. A coupling 731 is installed at the outer end of the output shaft of the cutting motor 73. A rotating spindle 76 is installed at the outer end of the coupling 731. A cutting saw blade 75 is installed on the circumferential surface of the rotating spindle 76. Air-cooling heat dissipation mechanisms 9 are symmetrically arranged on both sides of the cutting saw blade 75 to cool the outer surface and teeth of the cutting saw blade 75.
[0021] The aforementioned cutting saw blade 75 is made of cemented carbide, which can maintain its hardness at temperatures above 850°C, ensuring cutting efficiency and precision. The aforementioned annular heating furnace is existing technology and will not be described in detail here.
[0022] like Figure 1-2 As shown, in this embodiment, a plurality of feeding rollers 11 are rotatably arranged inside the feeding frame 1 to assist the movement of the wheel bar 8; Pushing frames 2 are symmetrically arranged on the front and rear sides of the feeding frame 1, and a single pushing frame 2 is arranged on the front side of the conveying frame 6. Each pushing frame 2 is equipped with a screw conveying mechanism 211 at its upper end. Above the feeding rack 1 is a push plate 21 that connects to the two screw conveyor mechanisms 211. The push plate 21 is fixedly engaged with the sliding block in the two screw conveyor mechanisms 211. The screw conveyor mechanism 211 drives the push plate 21 to move laterally above the feeding rack, thereby driving the wheel bar 8 to move. A pusher cylinder 22 is fixedly installed on the outer side of the pusher plate 21. The movable end of the pusher cylinder 22 passes through the pusher plate 21 and slides in cooperation with it, thereby assisting the pusher plate 21 to push the wheel bar 8 a second time, so that the cut wheel bar 8 enters the conveyor frame 6. A base 23 is provided on the outside of the conveyor frame 6. The base 23 is fixedly engaged with the sliding block in the screw conveyor mechanism 211 on the same side. A rotary motor 24 is fixedly provided on the outside of the base 23. A U-shaped discharge plate 25 is fixed on the output shaft of the rotary motor 24. The screw conveyor mechanism 211 drives the base 23 to move, and then the rotary motor 24 drives the U-shaped discharge plate 25 to rotate to the work position, so that the cut wheel bar 8 is pushed through the discharge plate 25.
[0023] The aforementioned lead screw transmission mechanism 211 is existing technology and will not be described in detail here.
[0024] like Figure 3-4 As shown, in this embodiment, the conveyor frame 6 is U-shaped, and a number of support frames 61 are symmetrically arranged on the inner bottom surface of the conveyor frame 6. Push rails 62, which are fixed to the support frames 61, are symmetrically fixed inside the conveyor frame 6. A support plate 65 is fixedly connected between the two push rails 62. The cut wheel bar 8 will contact the inclined surfaces of the push rails 62 on both sides. The push rails 62 and the support frame 61 support the wheel bar 8. There is a gap between the support plate 65 and the wheel bar 8. A connecting shaft 64 is symmetrically rotated inside the conveyor frame 6. The connecting shaft 64 is located at both ends of the support plate 65. A conveyor belt 66 is connected between the two connecting shafts 64. There is also a gap between the conveyor belt 66 and the wheel bar 8. The connecting shaft 64 drives the transmission belt to slide on the surface of the support plate 65. A motor 63 with an output shaft fixed to the connecting shaft 64 is fixed on the outer side of the conveyor frame 6.
[0025] Specifically, during the cutting process, some of the metal cutting debris falls onto the surface of the push rail 62 and the conveyor belt 66. Some of the debris on the inclined surface of the push rail 62 slides onto the conveyor belt 66. As the wheel bar 8 moves, another part of the debris falls onto the surface of the conveyor belt 66. Then, the motor 63 is started, causing the connecting shaft 64 to drive the conveyor belt 66 to move. The conveyor belt 66 carries away most of the metal cutting debris, preventing it from accumulating on the conveyor frame 6.
[0026] like Figure 1-2 As shown, in this embodiment, both the cutting frame 4 and the fixing frame 3 are trapezoidal, and both have a support frame 31 fixedly fixed on their upper surfaces. The pressing cylinder 32 on the fixing frame 3 and the cutting cylinder 41 on the cutting frame 4 are fixed to the corresponding support frame 31. A rubber head is fixedly installed on the outer side of the movable end of the pressing cylinder 32, and the movable end of the cutting cylinder 41 is fixed to the support frame 71.
[0027] like Figure 6-7As shown, in this embodiment, a plurality of grooves 411 are provided on the inclined surface of the cutting frame 4. A guide shaft 412 is fixedly provided in the groove 411. A slider 732 that slides in the groove 411 is symmetrically fixed at the lower end of the support frame 71. The cutting motor 73 is fixed to the slider 732. The guide shaft 412 passes through the slider 732 and slides to ensure the stability of the support frame 71 on the cutting frame 4.
[0028] like Figure 6-8 As shown, in this embodiment, a support frame 711 is vertically fixed on the outer surface of the support frame 71, and a connecting rod 712 is symmetrically fixed on the outer end of the support frame 711. An inverted U-shaped air inlet frame 72 is fixed on the outer end of the connecting rod 712. An air inlet 721 is opened on the upper surface of the air inlet frame 72, and a filter screen is installed at the air inlet 721 to prevent external debris from falling into the air inlet frame 72. Bearings are installed on both sides of the lower end of the air inlet frame 72 and rotate in conjunction with the rotating main shaft 76. A protective cover 74 is installed in the middle of the air inlet frame 72. The protective cover 74 has a through groove, which facilitates the air-cooled heat dissipation mechanism 9 to carry away the heat of the cutting saw blade 75, and also prevents cutting debris and broken saw teeth from flying.
[0029] like Figure 8-11 As shown, in this embodiment, the air-cooled heat dissipation mechanism 9 includes an air guide frame 91, a sleeve 94, an air outlet ring 93, and a symmetrically arranged air guide frame 92. The air guide frame 91 is fixedly installed on the side wall of the air inlet frame 72 by bolts and communicates with the inner cavity of the air inlet frame 72. The two air guide frames 2 92 are fitted onto the outside of the air guide frame 1 91 and then fastened together with bolts. The sleeve 94 is fixedly sleeved on the circumferential surface of the rotating spindle 76 and leaves a gap with the cutting saw blade 75. A connecting shaft 64 bearing is fixedly installed on the circumferential surface of the sleeve 94 near the cutting saw blade 75, and an intake fan blade 942 is fixedly installed away from the cutting saw blade 75. The outer ring of the connecting shaft 64 bearing is fixedly fitted with the inner wall of the first air guide frame 91, so that the rotation of the rotating main shaft 76 will not affect the first air guide frame 91 and the second air guide frame 92. The connection between the first air guide frame 91 and the second air guide frame 92 is provided with several interconnected ventilation slots in a circular shape, so that the fan blades 942 can guide the cooling air from the air inlet frame 72 and then guide it into the second air guide frame 92 along the first air guide frame 91. The other end of the air guide frame 292 is connected to the outside.
[0030] like Figure 8-11As shown, in this embodiment, symmetrically arranged clamps for fixing the cutting saw blade 75 are provided on the circumferential surface of the rotating spindle 76. One side of the fixed clamp 762 is welded to the circumferential surface of the rotating spindle 76, and the other side of the movable clamp 761 is sleeved on the circumferential surface of the rotating spindle 76. After the cutting saw blade 75 is clamped, bolts are used to pass through the fixed clamp 762 and the movable clamp 761 to fix the cutting saw blade 75. One side of the air outlet ring 93 is fixed on the circumferential surface of the fixed sleeve 762, and the other side of the air outlet ring 93 is fixed on the circumferential surface of the movable sleeve 761.
[0031] like Figure 12-14 As shown, in this embodiment, a gap is left between the air outlet ring 93 and the air guide frame 92 to prevent the rotation of the air outlet ring 93 from affecting the air guide frame 92. The air outlet ring 93 has several air inlets 931 circumferentially opened on the outer surface of the air guide frame 2 92. Since the distance between the outlet of the air guide frame 2 92 and the several air inlets 931 on the side of the air outlet ring 93 is very close (there is a very small gap), the cooling air can smoothly pass through this tiny "dynamic-static gap" under the action of pressure difference and enter the air inlet 931 of the rotating side air outlet ring 93 from the outlet of the stationary side air guide frame 2 92. The air outlet ring 93 has a number of heat dissipation vents 932 that communicate with the air guide vent 931 on its circumferential surface. Cooling air entering from the air guide vent 931 will be discharged to the outside through the heat dissipation vent 932 to cool the cutting saw blade 75 and the saw teeth. The air outlet position of the heat dissipation vent 932 is set outward to ensure that the discharged cooling air can cover the outer surface of the cutting saw blade 75.
[0032] like Figure 12-14 As shown, in this embodiment, an air outlet component 95 that can change the width of the air duct is provided inside the heat dissipation vent 932; The air outlet assembly 95 includes a U-shaped frame 951, which is fixed inside the heat dissipation vent 932. A sliding shaft 955 is symmetrically fixed in the upper and lower parts of the U-shaped frame 951. A sliding plate 952 is symmetrically slidably arranged on the circumference of the sliding shaft 955. The distance between the two sliding plates 952 is the air outlet duct of the heat dissipation vent 932. The width of the air outlet duct is adjusted by changing the distance between the two sliding plates 952, thereby changing the wind speed of the cooling air discharged from the heat dissipation vent 932. A spring 956, which is sleeved on the outside of the sliding shaft 955, is fixedly connected between the sliding plate 952 and the inner wall of the U-shaped frame 951. A rubber layer is fixedly connected between the upper end of the sliding plate 952 and the upper end face of the U-shaped frame 951. This rubber layer can stretch and deform. A push block 953 is slidably disposed between the sliding plate 952 and the inner wall of the U-shaped frame 951. Both the push block 953 and the sliding plate 952 are provided with inclined surfaces. The two inclined surfaces are in close contact and slide together. A second spring 957 is symmetrically fixedly connected between the push block 953 and the inner bottom surface of the U-shaped frame 951. The first spring 956 and the second spring 957 do not interfere with each other.
[0033] Specifically, during the cutting process of the wheel bar 8, the cutting saw blade 75 operates in two states: a waiting state (hereinafter referred to as the idle state) and a cutting state. The operating speed of the rotating spindle 76 in the waiting state is lower than that in the cutting state, and the operating speed of the rotating spindle 76 in the cutting state increases with the increase of the cutting feed. In the idling state, the rotating spindle 76 will generate centrifugal force during rotation, causing the push block 953 to move outward. At this time, the second spring 957 will pull the push block 953, and the first spring 956 will pull the sliding plate 952. The distance between the two sliding plates 952 changes little. In the cutting state, the increased speed of the rotating spindle 76 generates a stronger centrifugal force, causing the push block 953 to move further outward. As the push block 953 moves outward again, the sliding plates 952 on both sides will move closer together, and the air duct between them will become narrower. The narrowing of the air duct will further increase the exhaust air speed, which can better remove the heat generated by the cutting saw blade 75 and saw teeth during the cutting process. The exhaust cooling air will evenly cover the cutting saw blade 75, which can better dissipate heat from the cutting saw blade 75, extend the service life of the cutting saw blade 75, and the exhaust cooling air can also dissipate heat at the cutting position of the wheel bar 8 and blow away the cutting debris.
[0034] like Figure 15-19 As shown, in this embodiment, the cleaning mechanism 5 includes a drive component 51 and a dirt removal component 52 arranged sequentially from left to right, and an air blowing cleaning component 53 is arranged above the dirt removal component 52. The drive assembly 51 includes a protective frame 511 arranged symmetrically in front and behind and a rotating shaft 515 arranged symmetrically in the top and bottom. A protective frame 513 is symmetrically fixed on the outer side of the protective frame 511. The two ends of the rotating shaft 515 pass through the protective frames 511 and 513 on both sides and rotate in cooperation. The protective frame 511 is fixed to the feeding rack 1. A rubber roller 512 is fixedly installed on the central circumferential surface of the rotating shaft 515. The rubber roller 512 fits tightly against the wheel bar 8 that is transported there. The movement of the subsequent wheel bar 8 drives the rubber roller 512 and the rotating shaft 515 to rotate. The upper rubber roller 512 and the lower rotating roller rotate in opposite directions.
[0035] like Figure 19 As shown, in this embodiment, two sets of fixed seats 517 are symmetrically arranged inside the first protective frame 511. A second rotating shaft 516 is vertically rotatably arranged inside each set of fixed seats 517. A meshing bevel gear 526 is fixedly arranged at the outer end of the second rotating shaft 516 and the first rotating shaft 515. A drive shaft 527 is arranged at the corresponding end of the two second rotating shafts 516. A third protective frame 514 is horizontally fixedly arranged on the outer side of the protective frame. The drive shaft 527 is arranged inside the third protective frame 514 and passes through the first protective frame 511 and rotates. A bevel gear 526 that meshes with the bevel gear 526 at the end of the second rotating shaft 516 is fixedly arranged at the end of the drive shaft 527 inside the first protective frame 511. The diagram shows the rotation directions of shaft 1 (515) and shaft 2 (516).
[0036] Specifically, when the movement of the wheel bar 8 causes the rubber rollers 512 on the upper and lower sides to rotate, the bevel gear 526 above the first shaft 515 will drive the second shaft 516 to rotate, thereby driving the horizontally placed drive shafts 527 on both sides to rotate, and the rotation directions of the two drive shafts 527 are opposite.
[0037] like Figure 15-18 As shown, in this embodiment, the impurity removal component 52 includes a mounting frame 521, which is fixed to the feeding frame 1. The mounting frame 521 has a circular through groove, and fixing rings 522 are symmetrically arranged in the through groove. The two fixing rings 522 are joined together by bolts and fixed to the mounting frame 521. A groove 5222 is provided inside the fixed ring 522, and a toothed ring 524 is rotatably provided inside the groove 5222. An annular cover 528 is fixed to the outside of the fixed ring 522 by bolts to protect the toothed ring 524. A gear 526 is engaged at one side of the gear ring 524 near the protective frame 511, and a gear 526 is also engaged at the other side of the gear ring 524 away from the protective frame 511. The two gears 526 are fixed to the drive shafts 527 on both sides respectively. The drive shafts 527 drive the gears 526 to rotate, which in turn drives the gear ring 524 to rotate. The drive shafts 527 on both sides rotate in opposite directions, so the gear rings 524 on both sides also rotate in opposite directions.
[0038] like Figure 15-18 As shown, in this embodiment, an annular steel brush 525 is fixedly provided on the inner ring of the toothed ring 524, and the inner diameter of the steel brush 525 is adapted to the diameter of the wheel bar 8.
[0039] Specifically, the toothed ring 524 drives the steel brush 525 to rotate, thereby brushing away the rust and impurities on the circumferential surface of the wheel bar 8. The brushed impurities will detach from the circumferential surface of the wheel bar 8, and some of the detached impurities and dust will fall back onto the circumferential surface of the wheel bar 8. When the wheel bar 8 passes the cutting saw blade 75, the cutting saw blade 75 is in an idling state, and the adhering impurities will be blown off by the cooling air discharged from the air outlet ring 93, thereby improving the cleaning effect on the wheel bar 8. Some of the detached impurities will remain between the two steel brushes 525. These impurities can be removed from the gap between the two steel brushes 525 by the air-blowing cleaning component 53.
[0040] like Figure 5 and Figure 15-18 As shown, in this embodiment, the air blowing cleaning assembly 53 includes a piston rod 532, an air storage cylinder 531, and a support rod 534. The upper end of the support rod 534 is fixed to the air storage cylinder 531 to support the air storage cylinder 531. The lower end of the support rod 534 is fixed to the upper surface of the mounting bracket 521 by bolts. The piston rod 532 is slidably disposed inside the air storage cylinder 531, and a connecting seat 533 is fixedly disposed at the upper end of the piston rod 532. The connecting seat 533 is fixed to the outer side of the air inlet frame 72 by bolts. The piston rod 532 moves with the movement of the air inlet frame 72. An exhaust check valve 536 is installed at the lower outlet of the air storage cylinder 531. A rubber hose 535 communicating with the inner cavity of the air storage cylinder 531 is fixedly installed at the lower end of the exhaust check valve 536. An intake check valve 537 communicating with the inner cavity is fixedly installed on the outer side of the air storage cylinder 531 near the lower end. When the piston rod 532 moves downward, it will push the air in the air reservoir 531 into the rubber hose 535 through the one-way valve 536 and then discharge it. When the piston rod 532 moves upward, outside air will re-enter the air reservoir 531 through the intake check valve 537.
[0041] The aforementioned exhaust check valve 536 and intake check valve 537 are both existing technologies and will not be described in detail here.
[0042] like Figure 15-18 As shown, in this embodiment, the outer surfaces of the two fixed rings 522 are provided with downward-facing discharge channels 5221, and the mounting frame 521 is provided with a discharge port 5211 communicating with the discharge channels 5221. A detachable cloth bag is installed at the outlet of the discharge port 5211 of the mounting frame 521 to collect impurities between the two steel brushes 525. Furthermore, an exhaust vent 523 communicating with the material discharge groove 5221 is provided at the upper end of the mounting bracket 521, and the lower end of the rubber hose 535 is connected to the exhaust vent 523. An air outlet frame 54 is fixedly installed inside the feeding channel 5221. Several exhaust heads are fixedly installed on the outer surface of the air outlet frame 54. The air discharged from the rubber hose 535 is guided to the feeding channel 5221 through the exhaust heads, and then the impurities between the two steel brushes 525 are blown off, so that the impurities pass through the feeding channel 5221 and the feeding port 5211 and enter the cloth bag.
[0043] The aforementioned cloth bag is existing technology and will not be drawn or described in detail here.
[0044] The work process is as follows: The wheel bar 8 is placed on the feeding roller 11 of the feeding frame 1, and then the wheel bar 8 is pushed by the push plate 21. The wheel bar 8 passes through the rubber roller 512 and the steel brush 525 and enters the cutting point. During the movement, the rotation of the rubber roller 512 on the upper and lower sides will drive the steel brush 525 on both sides to rotate in different directions, which improves the cleaning effect on the circumference of the wheel bar 8. When the wheel bar 8 passes the cutting saw blade 75, the cutting saw blade 75 is already in an idling state, which can blow off the impurities attached to the surface of the wheel bar 8. After the wheel bar 8 moves to the cutting point, the clamping cylinder 32 clamps and fixes the wheel bar 8 to ensure the stability of the wheel bar 8 during the cutting process. When cutting begins, the cutting cylinder 41 drives the support frame 71 to move diagonally downwards, and the air inlet frame 72 drives the piston rod 532 to slide inside the air storage cylinder 531, discharging the air in the air storage cylinder 531 into the material discharge channel 5221, blowing off the impurities between the two steel brushes 525. As the feed rate increases, the speed of the rotating spindle 76 increases, generating a stronger centrifugal force that causes the push block 953 to move further outward. As the push block 953 moves outward again, the sliding plates 952 on both sides will move closer together, and the air duct between them will become narrower. The narrowing of the air duct will further increase the exhaust air velocity, which can better remove the heat generated by the cutting saw blade 75 and the saw teeth during the cutting process. The exhaust cooling air will evenly cover the cutting saw blade 75, which can better dissipate heat from the cutting saw blade 75, extend the service life of the cutting saw blade 75, and the exhaust cooling air can also dissipate heat at the cutting position of the wheel bar 8 and blow away the cutting debris. After cutting, the cutting cylinder 41 drives the support frame 71 to reset. During the reset process, the speed of the rotating spindle 76 is adjusted to a slow idle speed. At the same time, the air inlet frame 72 drives the piston rod 532 to reset. Outside air enters the Andon air storage cylinder 531 again through the air inlet one-way valve 537. Then the pressing cylinder 32 resets, releasing the pressure on the wheel bar 8. Subsequently, the push plate 21 continues to drive the remaining wheel bar 8 to the cutting point. The rotating motor 24 drives the discharge plate 25 to move, so that the discharge plate 25 enters between the cutting surfaces of the two wheel bars 8. Finally, the screw transmission mechanism 211 on the push frame 2 drives the base 23 to move, so that the discharge plate 25 pushes the cut wheel bar 8 out along the push rail 62.
