[0006] In some embodiments, the actuating unit further includes: a fourth bracket connected to the third base and located above the conveying channel; and a sixth motor connected to the fourth bracket, the output shaft of the sixth motor being connected to the center of the actuating plate.

[0007] In some embodiments, the processing assembly includes: a housing extending along a direction perpendicular to the first direction; two sets of first push rods, each set positioned on opposite sides of the housing along the first direction, with the top end of each first push rod connected to the housing and the bottom end of each first push rod connected to a first base; two first bases, each positioned on opposite sides of the housing along the first direction, connected to the worktable, with the bottom end of each set of first push rods connected to the first base on the same side; two first drive wheels, arranged opposite each other along a second direction, rotatably connected to the housing, the second direction being perpendicular to the first direction; a saw blade fitted onto the two first drive wheels; and a first bracket connected to the housing, with two support rollers rotatably connected to the first bracket, the two support rollers arranged opposite each other along the second direction and located between the two first drive wheels, the outer circumferential surface of the support rollers having a first groove adapted to the thickness of the saw blade to change the shape of the saw blade.

[0008] In some embodiments, the processing assembly further includes: clamping plates, two of which are disposed on the top of each of the first bases, the two clamping plates being movable relative to or away from each other along the second direction to clamp the bar to be processed.

[0009] In some embodiments, the feeding assembly includes: a second base connected to the worktable at its bottom, the second base and the first base being sequentially connected along the first direction; two first baffles disposed opposite each other on the top of the second base along the second direction; and a correction unit including a third bracket and pressure rollers, wherein the third bracket is disposed above the side of the second base facing the first base, and a plurality of pressure rollers are sequentially and rotatably connected to the third bracket at intervals along the first direction.

[0010] In some embodiments, the correction unit further includes an infrared module, comprising an infrared transmitter and an infrared receiver that cooperate with each other, the infrared transmitter and the infrared receiver being disposed opposite to each other on the third support along a second direction, and respectively located on both sides of the rod.

[0011] In some implementations, the correction unit further includes: a first connecting frame movably connected to the third support along the first direction, and the infrared module connected to the first connecting frame.

At this point, the actuating unit drives the actuating plate to deflect to the corresponding orientation based on the confirmed bar stock information. For example, if the infrared module detects that the remaining bar stock length is sufficient for the next cut, the actuating plate deflects to guide the finished product into one side of the guide plate, and the finished product is diverted from the feeding port onto the guide plate. If the infrared module detects that the remaining bar stock length is insufficient, it drives the actuating plate to deflect to the other side, allowing the remaining material to enter the other side of the guide plate through another feeding port, thus achieving automatic diversion of finished products and remaining material.

[0016] This application enables finished products and scrap materials to be sorted and diverted through a discharge component when scrap materials may be generated during bar processing, thus avoiding the impact on processing efficiency and waste of manpower caused by manual sorting of finished products and scrap materials.

[0020] To enable those skilled in the art to more clearly understand this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0021] Figure 1 This illustration shows a schematic diagram of a CNC band saw for cutting axle-type automotive parts according to one or more embodiments of this application. (Combined with...) Figure 1 The CNC band saw includes a worktable 1 and a feeding assembly 21, a processing assembly 20, and a discharging assembly 23 arranged sequentially on the worktable 1 along a first direction. After the bar to be processed is conveyed to the worktable by the feeding assembly 21, the bar is cut into finished products that meet the length requirements by the processing assembly 20. During the processing, there may be leftover material. Finished products and leftover material are sorted and diverted by the discharging assembly 23 to avoid the impact on processing efficiency and waste of manpower caused by manual sorting of finished products and leftover material.

[0022] To describe the directions, the first direction is defined as the front-back direction, and the second direction, which is perpendicular to the first direction, is defined as the left-right direction. The specific settings of the CNC band saw are further described below with reference to the accompanying drawings.

[0023] In some embodiments, the workbench 1 has a certain height to facilitate manual observation and operation, and the top surface of the workbench 1 is preferably flat to facilitate the arrangement of components.

[0024] Figure 2 It shows Figure 1 A schematic diagram of the processing components in the diagram. Figure 3 It shows Figure 1 A cross-sectional schematic diagram, Figure 4 A schematic diagram of the motion of the processing components is shown. (Combined with...) Figure 2 as well as Figure 3In some embodiments, the processing component 20 includes a housing 203, a first push rod 202, a first base 201, a first drive wheel 204, a saw blade 208, and a first bracket 206. The housing 203 extends along a second direction and is located above the worktable 1. Two sets of first push rods 202 are provided, with the two sets of first push rods 202 respectively located on both sides of the housing 203 in the front-rear direction. The top end of each first push rod 202 is connected to the housing 203. Two first bases 201 are provided, with the two first bases 201 respectively located on both sides of the housing 203 in the front-rear direction. The first bases 201 are connected to the worktable 1. The bottom end of each set of first push rods 202 is connected to the first base 201 on the same side. Therefore, by controlling the movement of the first push rods 202, the housing 203 can be driven to rise and fall. Two first drive wheels 204 are arranged opposite each other in the left-right direction and are rotatably connected to the housing 203. The saw blade 208 is sleeved on the two first drive wheels 204. A first bracket 206 is connected to the housing 203, and two support rollers 207 are rotatably connected to the first bracket 206. The two support rollers 207 are arranged opposite each other in the left-right direction and are located between the two first drive wheels 204. The outer circumferential surface of the support rollers 207 is provided with a first groove adapted to the thickness of the saw blade 208 to change the shape of the saw blade 208. Since the action of the first push rod 202 can drive the housing 203 to rise and fall, it can drive the saw blade 208 to rise and fall, thereby processing the bar material positioned on the worktable 1 (such as...). Figure 4 (As shown).

[0025] Combination Figure 2 as well as Figure 3 Specifically, a second bracket 209 is fixedly connected to the outer wall of the housing 203. A first push rod 202 is fixedly connected to both the front and rear sides of the second bracket 209. The first push rod 202 can be an electric push rod, and there are two first push rods 202 on each side. A first base 201 is fixedly connected to the bottom of each first push rod 202. There are two first bases 201, respectively located on the front and rear sides of the housing 203. The bottom of the first base 201 is fixedly connected to the worktable 1. The inner wall of the housing 203 is rotatably connected to a first... A first motor 205 is fixedly connected to the outer wall of the drive wheel 204 and the housing 203. The output end of the first motor 205 is fixedly connected to the first drive wheel 204. A saw blade 208 is sleeved on the first drive wheel 204. A first push rod 202 is used to change the height of the saw blade 208. A first bracket 206 is fixedly connected to the inner wall of the housing 203. A support roller 207 is rotatably connected to the inner wall of the first bracket 206 through a bearing. The support roller 207 is used to adjust the orientation of the saw blade 208 so as to change the horizontal saw blade 208 into a vertical saw blade 208.

[0026] Combination Figure 2 as well as Figure 3In some embodiments, the processing assembly 20 further includes clamping plates 2011. Two clamping plates 2011 are disposed on the top of each first base 201. The two clamping plates 2011 can move relative to or away from each other along a second direction to clamp the bar to be processed. When the bar needs to be cut, after clamping the bar to be processed using the two clamping plates 2011 on the top of each first base 201, the first push rod 202 is controlled to descend, and the bar can then be cut using the saw blade 208.

[0027] In some embodiments, the opposing surfaces of the two clamping plates 2011 are arc-shaped to fit the bar, and the opposing surfaces of the two clamping plates 2011 are textured to ensure the reliability of clamping the bar.

[0028] Combination Figure 2 as well as Figure 3 Specifically, the inner wall of the first base 201 is rotatably connected to the first screw 2014 via bearings, and the outer wall of the first base 201 is fixedly connected to the second motor 2013. The output end of the second motor 2013 is fixedly connected to the first screw 2014, and the outer wall of the first screw 2014 is bolted to the first connecting plate 2012. The inner wall of the first connecting plate 2012 is fixedly connected to the U-shaped plate 2010, and the end of the U-shaped plate 2010 away from the first connecting plate 2012 is fixedly connected to the clamping plate 2011. The rotation of the second motor 2013 is used to drive the clamping plate 2011 to move. When processing the bar, the bar to be cut is conveyed to the cutting area through the feeding assembly 21. At this time, the second motors on both sides... The first screw 2014 is driven to rotate, and the first connecting plate 2012 moves, which in turn drives the clamping plate 2011 to clamp and fix the bar through the U-shaped plate 2010. At the same time, the first motor 205 drives the first drive wheel 204 to rotate, which in turn drives the saw blade 208 sleeved on the outer wall to move continuously in one direction. Then, the first push rod 202 is activated, which drives the housing 203 to move in the vertical direction, so that the saw blade 208 can smoothly cut into the bar and complete the cutting action. After the cutting is completed, the clamping plate 2011 moves in the opposite direction under the drive of the second motor 2013, releases the bar, and allows the saw blade 208 to reset. Then, it is transported to the discharge assembly 23 for subsequent diversion processing through the conveyor belt 2017.

[0029] Figure 5 A schematic diagram of the feeding assembly is shown. Figure 6 A schematic diagram of the correction unit is shown, combined with Figure 5 as well as Figure 6In some embodiments, the feeding assembly 21 includes a second base 211, a first baffle 212, and a correction unit 22. The bottom of the second base 211 is connected to the workbench 1, and the second base 211 and the first base 201 are connected sequentially in the front-back direction. Two first baffles 212 are arranged opposite each other on the top of the second base 211 in the left-right direction. The correction unit 22 includes a third bracket 222 and pressure rollers 2210. The third bracket 222 is arranged above the side of the second base 211 facing the first base 201. Multiple pressure rollers 2210 are sequentially and intermittently rotatably connected to the third bracket 222 in the first direction to assist in conveying the bar to be processed into place.

[0030] Combination Figure 5 as well as Figure 6 In specific implementation, the bottom of the second base 211 of the feeding assembly 21 is fixedly connected to the workbench 1, the front end of the second base 211 is fixedly connected to the rear side of the first base 201, and the two sides of the top of the second base 211 are fixedly connected to the first baffles 212. The two first baffles 212 and the top surface of the second base 211 enclose and form a conveying channel for the movement of the bar.

[0031] Combination Figure 6 Specifically, the correction unit 22 also includes a second connecting plate 221, which is fixedly disposed on the top of the second base 211 in the left-right direction. A third bracket 222 is fixedly connected to the top of the second connecting plate 221. A third connecting plate 223 is fixedly connected to the end of the third bracket 222 away from the second connecting plate 221. The end of the third connecting plate 223 away from the second connecting plate 221 is fixedly connected to the first base 201. A pressure roller 2210 is rotatably connected to the inner side of the second connecting plate 221 via a bearing. The outer wall of the pressure roller 2210 is provided with a second groove for conforming to the bar stock being processed. When the equipment is working, as the bar stock is conveyed forward, the pressure roller 2210 contacts the surface of the bar stock being processed. The second groove on the outer wall of the pressure roller 2210 plays an auxiliary limiting and stabilizing guiding role, preventing the bar stock from deviating during movement and ensuring that the bar stock is on the correct cutting path.

[0032] In some embodiments, the correction unit 22 further includes an infrared module 229, which includes an infrared transmitter and an infrared receiver that cooperate with each other. The infrared transmitter and the infrared receiver are arranged opposite each other on the third bracket 222 in the left-right direction and are located on both sides of the bar. During the cutting process, the infrared transmitter of the infrared module 229 emits an infrared signal to the infrared receiver. If the infrared receiver does not receive the infrared signal from the other side, it indicates that there is a bar blockage in the signal path, that is, the remaining bar length is sufficient to meet the requirements of the next cutting. Conversely, if the infrared receiver of the infrared module 229 receives an infrared signal, it indicates that the bar has moved out of the detection area and the remaining length is insufficient. The system thus prevents the remaining material from entering the next round of cutting.

[0033] Combination Figure 5 as well as Figure 6 In specific implementation, a second screw 224 is rotatably connected to the outer side of the third bracket 222, a fourth motor 225 is fixedly connected to the outer wall of the second connecting plate 221, the output end of the fourth motor 225 is fixedly connected to the second screw 224, a first slider 226 is movably connected to the outer wall of the third bracket 222, a first connecting frame 227 is fixedly connected to the top of the first slider 226, a connecting block 228 is fixedly connected to the outer wall of the first slider 226, and the inner wall of the connecting block 228 is threadedly connected to the second screw 224. That is, by controlling the fourth motor 225 to start, the first slider 226 and the first connecting frame 227 can be moved in the front-back direction. The infrared transmitter and infrared receiver of the infrared module 229 are respectively located at the bottom ends of two first sliders 226, meaning that the fourth motor 225 can change the position of the infrared module 229 and the first connecting frame 227 via the second screw 224. That is, the first connecting frame 227 is movably connected to the third bracket 222 along the first direction, and the infrared module 229 is connected to the first connecting frame 227. The infrared module 229 and the first connecting frame 227 can move synchronously along the front-back direction.

[0034] Combination Figure 6 In some embodiments, the feeding assembly 21 further includes a first rangefinder 2211, which is connected to the third bracket 222 and disposed on the side of the first connecting frame 227 facing away from the housing 203. For the specific configuration and function of the first rangefinder 2211, please refer to the relevant description below, which will not be repeated here.

[0035] Figure 7 A schematic diagram of the discharge assembly is shown. (Combined with...) Figure 7The discharge assembly 23 includes a third base 231, a guide plate 234, and a toggle unit. The bottom of the third base 231 is connected to the workbench 1. A conveying channel 231a is provided on the third base 231, and feeding ports 231b are provided on both sides of the conveying channel 231a. Two guide plates 234 are respectively connected to the two sides of the third base 231. One side of the guide plate 234 is connected to the lower side of the feeding port 231b on the same side. The other side of the guide plate 234 extends away from the third base 231, and the other side of the guide plate 234 is lower than the first side of the guide plate 234, that is, at least part of the guide plate 234 extends downward at an angle. The toggle unit is connected to the third base 231. The toggle unit has a rotatable toggle plate 238. At least part of the toggle plate 238 is rotatably disposed in the conveying channel 231a and located between the two feeding ports 231b. After the bar is cut, it is conveyed above the third base 231. At this time, the actuating unit drives the actuating plate 238 to deflect to the corresponding orientation based on the confirmed bar information. For example, if the infrared module 229 detects that the remaining bar length is sufficient for the next cut, the actuating plate 238 deflects to guide the finished material into one side guide plate 234, and the finished material is diverted from the feed port 231b onto the guide plate; if the infrared module 229 detects that the remaining bar length is insufficient, it drives the actuating plate 238 to deflect to the other side, so that the remaining material enters the other side guide plate 234 through another feed port 231b, thereby realizing the automatic diversion of finished product and remaining material.

[0036] Combination Figure 7 Specifically, the bottom of the third base 231 of the discharge assembly 23 is fixedly connected to the workbench 1, the rear side of the third base 231 is fixedly connected to the first base 201, and guide plates 234 are fixedly connected to the left and right sides of the end of the third base 231 away from the first base 201. Feeding ports 231b are opened at the ends of the two guide plates 234 away from the third base 231.

[0037] Combination Figure 7 In some embodiments, the actuation unit further includes a fourth bracket 236 and a sixth motor 237. The fourth bracket 236 is connected to the third base 231 and is located above the conveying channel 231a. The sixth motor 237 is connected to the fourth bracket 236, and the output shaft of the sixth motor 237 is connected to the middle of the actuation plate 238. Specifically, the fourth bracket 236 is fixedly connected to the top of the third base 231, the sixth motor 237 is fixedly connected to the top of the fourth bracket 236, and the actuation plate 238 is rotatably connected to the bottom of the fourth bracket 236 via a bearing. The output end of the sixth motor 237 is fixedly connected to the actuation plate 238. The sixth motor 237 is used to adjust the deflection direction of the actuation plate 238. The sixth motor 237 is linked with the infrared module 229 to perform corresponding actuation actions according to the confirmation information from the infrared module 229.

[0038] Specifically, the CNC band saw also includes a control system, which is electrically connected to the infrared module 229 and the sixth motor 239. The control system is configured to: receive the detection signal from the infrared module 229, and determine whether the remaining bar length meets the requirements for the next cutting based on the detection signal; if it does, control the sixth motor 237 to drive the actuating plate 238 to deflect to the first position, so that the bar enters the guide plate 234 from one feed port 231b; if it does not meet the requirements, control the sixth motor 237 to drive the actuating plate 238 to deflect to the second position, so that the bar enters the guide plate 234 from another feed port 231b.

[0039] Combination Figure 7 In some embodiments, the upper part of the guide plate 234 can extend horizontally, and the lower part can be inclined as a whole. A discharge port 235 can be provided at the lower part of the guide plate 234, through which finished products and waste materials can be collected. Baffles can be provided on the sides and bottom edges of the guide plate 234 to restrict the movement direction of finished products and waste materials on the corresponding guide plate 234. For example, the angle between the guide plate 234 and the horizontal plane is 15° to 45° to ensure that the bar material slides smoothly under gravity.

[0040] Figure 8 It shows Figure 7 The enlarged diagram at point A in the diagram, combined with... Figure 7 as well as Figure 8 In some embodiments, the discharge assembly 23 further includes two relatively openable limiting plates 2316. The two limiting plates 2316 are rotatably connected to the third base 231 and located between the housing 203 and the actuating unit to position the bar stock to be processed. Specifically, when the bar stock needs to be processed and cut, the two limiting plates 2316 close onto the conveying path of the bar stock. Then, the bar stock is controlled to be conveyed to the third base 231 and move against the two limiting plates 2316. At this time, the processing assembly 20 can be operated to cut the bar stock. After cutting is completed, the two limiting plates 2316 are controlled to flip open, and the bar stock can be continued to be conveyed to the actuating unit for sorting of finished products and scrap.

[0041] In some embodiments, the two limiting plates 2316 can move along the front-back direction on the third base 231 and can be locked onto the third base 231. This configuration can accommodate the processing of bars with different length requirements.

[0042] Combination Figure 7 as well as Figure 8In specific implementation, a fourth connecting plate 239 is fixedly connected to the outer wall of the third base 231, and a sliding column 2311 is fixedly connected to the outer wall of the fourth connecting plate 239. One end of the sliding column 2311 away from the fourth connecting plate 239 is fixedly connected to the first base 201. A second slider 2312 is movably connected to the outer wall of the sliding column 2311. A fastening bolt 2313 is threadedly connected to the outer wall of the second slider 2312, and a second connecting bracket 2314 is fixedly connected to the top of the fastening bolt 2313. The outer wall of the connecting frame 2314 is fixedly connected to the seventh motor 2315. The inner wall of the second connecting frame 2314 is rotatably connected to the limit plate 2316 through the bearing. The inner wall of the second connecting frame 2314 is fixedly connected to the blocking column 2317. When the fastening bolt 2313 is tightened, it is used to fix the position of the second slider 2312 on the sliding column 2311, that is, to lock the position of the two limit plates 2316 on the third base 231. The seventh motor 2315 is used to control the deflection of the limit plate 2316.

[0043] After the bar stock is cut, the processed bar stock is conveyed to the top of the third base 231. At this time, the sixth motor 237 will drive the deflector plate 238 to deflect to the corresponding orientation according to the detection result of the infrared module 229. If the infrared module 229 detects that the remaining bar stock length is sufficient for the next cut, the sixth motor 237 will deflect the deflector plate 238 to guide the finished material into the side pouring plate, and the finished material will be discharged from the corresponding outlet 235 along the pouring plate. If the infrared module 229 detects that the remaining bar stock length is insufficient, the sixth motor 237 will deflect the deflector plate 238 to the other side, so that the remaining material enters the other side pouring plate and is discharged from the corresponding outlet 235, realizing the automatic diversion of finished product and remaining material.

[0044] Combination Figure 7 In some embodiments, the discharge assembly 23 further includes a second rangefinder 2310, which is connected to the third base 231. Exemplarily, the second rangefinder 2310 is fixedly connected to the outer wall of the fourth connecting plate 239.

[0045] Before processing, the position of the second slider 2312 on the sliding column 2311 is first adjusted according to the required finished product length. When the second slider 2312 moves, it drives the second connecting frame 2314, the seventh motor 2315, the limit plate 2316, and the blocking column 2317 to move synchronously. After the second slider 2312 moves to the target position, the fastening bolt 2313 is tightened to fix the second slider 2312 and its accessories on the sliding column 2311, completing the mechanical setting of the cutting length. At the same time, the second rangefinder 2310 on the fourth connecting plate 239 detects the relative position of the second slider 2312 in real time. The distance measured by the second rangefinder 2310 is transmitted to the main controller as a basic value. Based on this basic value, the main controller automatically adjusts the detection position of the infrared module 229 in the auxiliary component to ensure that the infrared module 229 can accurately determine whether the length of the remaining bar meets the requirements for the next cutting. During cutting, the bar is conveyed forward, and its end first contacts the limiting plate 2316. After cutting, the seventh motor 2315 drives the limiting plate 2316 to deflect outward to make room for the cut bar. The bar passes smoothly through the position of the limiting plate 2316 and enters the subsequent diversion stage.

[0046] The first rangefinder 2211 and the second rangefinder 2310 provided in this application both employ industrial-grade laser rangefinders. The first rangefinder 2211 is fixedly mounted on the third bracket 222, located on the side of the first connecting frame 227 facing away from the housing 203, and is used to detect the displacement of the first connecting frame 227 along a first direction, thereby determining the position of the infrared module 229. The second rangefinder 2310 is connected to the fourth connecting plate 239 of the third base 231, and is used to detect the distance of the second slider 2312 relative to the fourth connecting plate 239 in real time, thereby determining the positions of the two limiting plates 2316. Specific models can be selected from the Keyence IL series CMOS laser displacement sensors, such as the IL-065 type. Of course, other types of rangefinders can also be used, and this application does not impose any restrictions on this.

[0047] Combination Figure 7In some embodiments, a fifth motor 233 is fixedly connected to the end of the third base 231 away from the first base 201. A third drive wheel 232 is rotatably connected to the inner wall of the end of the third base 231 away from the first base 201 via a bearing. The output end of the fifth motor 233 is fixedly connected to the third drive wheel 232. A third motor 214 is fixedly connected to the end of the second base 211 away from the first base 201. A second drive wheel 213 is rotatably connected to the inner wall of the end of the second base 211 away from the first base 201 via a bearing. The output end of the third motor 214 is fixedly connected to the second drive wheel 213. A conveyor belt 2017 is sleeved on the outer wall of the second drive wheel 213. The second drive wheel 213 is rotatably connected to the third drive wheel 232 via the conveyor belt 2017. The fifth motor 233 and the third motor 214 are used to drive the conveyor belt 2017 to move.

[0048] Figure 9 It shows Figure 1 A cross-sectional schematic diagram, combined with Figure 9 In some embodiments, the top of the workbench 1 is fixedly connected to the outer frame 2015, and the inner wall of the outer frame 2015 is rotatably connected to the rotating roller 2016 via bearings. The conveyor belt 2017 is sleeved on the outer wall of the rotating roller 2016. There are three rotating rollers 2016, which are used to change the height of the conveyor belt 2017 at the saw blade 208.

[0049] Figure 10 A schematic diagram of the assembly of the rotating roller and the conveyor belt is shown. (Combined with...) Figure 10 Specifically, the three drive rollers 2016 are defined as the first drive roller 20161, the second drive roller 20162, and the third drive roller 20163, respectively. The first drive roller 20161 is located directly below the saw blade 208 and presses the conveyor belt 2017. The second drive roller 20162 and the third drive roller 20163 support the conveyor belt 2017, thereby forming a beveled shape for the conveyor belt to face the saw blade 208 in order to avoid the saw blade 208 and meet the processing of the bar by the saw blade 208.

[0050] Testing showed that using the CNC band saw of this application for blanking shaft-type automotive parts can increase single-batch processing efficiency by approximately 30%–50% and reduce labor costs by approximately 40%–60% compared to traditional manual sorting methods. Furthermore, by avoiding human error, raw material utilization is increased by approximately 5%–10%. Taking the blanking of a typical automotive half-shaft blank as an example, approximately 1.5 hours of manual sorting time can be saved per 8-hour shift, while reducing waste caused by misjudgment by approximately 2%. The above data are the comparison results between the experimental prototype and a traditional band saw with manual sorting under the same working conditions, fully demonstrating the significant progress of this application.

[0051] This application enables finished products and scrap materials to be sorted and diverted through a discharge component when scrap materials may be generated during bar processing, thus avoiding the impact on processing efficiency and waste of manpower caused by manual sorting of finished products and scrap materials.
