Description

Technical Field

[0001] This invention relates to the field of cutting device technology, specifically to a cutting device for automotive parts. Background Technology

[0002] Automotive parts refer to the various components that make up a car as a whole, as well as related accessories, including cylinder blocks, cylinder heads, shock absorbers, stabilizer bars, etc. In the production of cylinder barrels, a cutting device is often used to cut long strips of aluminum alloy profiles into multiple cylinder barrels of the same size.

[0003] In traditional cutting devices, the cutting part is often directly fixed to the operating table with bolts, thus keeping its position constant. Therefore, if the cutting blade gets stuck in the material or encounters excessive resistance during the cutting process, a rebound force may be generated, causing the cutting blade to move suddenly upward or in other directions, which may cause injury to the operator. This makes the device impractical.

[0004] During the cutting of aluminum alloy profiles, the cutting part of the equipment is fixed to the operating table with bolts. When cutting aluminum alloy profiles of different sizes, the vertical position of the cutting blade is constant. Therefore, it is necessary to adjust the position of the cutting part or replace the cutting blade with a different radius by removing the bolts. The operation process is cumbersome and lacks flexibility.

[0005] During the cutting of aluminum alloy profiles, operators need to move multiple aluminum alloy profiles onto the operating table and align their ends with the clamps on the equipment. Then, during the cutting process, operators need to repeatedly turn the equipment off and on and add aluminum alloy profiles. The operation is cumbersome and results in low cutting efficiency.

[0033] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0034] like Figure 4 and Figures 6-9As shown, the present invention discloses an automotive parts cutting device, comprising a cutting machine body 1, a conveying structure 2 mounted on the cutting machine body 1, a feeding structure 3 mounted on the cutting machine body 1, a braking structure 5 disposed inside the cutting machine body 1, a height adjustment structure 6 connected to the braking structure 5, and a cutting structure 7 disposed on the height adjustment structure 6. The braking structure 5 includes six load-bearing beams 501 and two guide plates 502 fixedly connected between two of the load-bearing beams 501. Three load-bearing beams 501 are fixedly connected to the inner walls of both sides of the cutting machine body 1. A support plate 504 is slidably connected between two guide plates 502. Two third guide rods 507 are fixedly connected between the three load-bearing beams 501 on the same side. A docking block 508 is slidably connected between the two third guide rods 507. The docking block 508 is slidably connected to the outer wall of the guide plate 502. Two locking blocks 509 are slidably connected inside the docking block 508. A spring 511 is fixedly connected between the inner walls of the locking block 509 and the docking block 508. A pull rod 510 is fixedly connected between the ends of the two locking blocks 509. The pull rod 510 is slidably connected to the docking block 508. The other ends of the two locking blocks 509 are engaged with grooves on the support plate 504. A height adjustment structure 6 is connected to the support plate 504. A cutting structure 7 is fitted on the height adjustment structure 6. A second guide rod 5 is fixedly connected inside the two guide plates 502. 03, the support plate 504 is slidably connected to the second guide rod 503, both ends of the support plate 504 are fixedly connected to the inner wall of the guide plate 502 with tension springs 505, the bottom of the two guide plates 502 are fixedly connected with limit blocks 506, the two load-bearing beams 501 near the guide plate 502 are rotatably connected with a second lead screw 512, the docking block 508 is threadedly connected to the second lead screw 512, and the bottom of the second lead screw 512 is fixedly connected with a knob 513;During the cutting process, if abnormal phenomena such as the saw blade 704 being stuck by the aluminum alloy profile 4 or experiencing excessive resistance are found, in order to avoid damage to the saw blade 704 or fragments flying in all directions, simply pull the pull rod 510 on the side of the cutting machine body 1. The pull rod 510 will then drive the two locking blocks 509 inside the connecting block 508 to slide outwards. At the same time, one of the locking blocks 509 compresses the spring 511 until the two locking blocks 509 are no longer engaged with the groove on the support plate 504. At this time, the support plate 504 and the mounting plate 508 will be properly secured. The cutting section mounted above moves rapidly downwards under the force of gravity and the tension of the spring 505, causing the saw blade 704 to move rapidly downwards until it is completely retracted into the interior of the cutting machine body 1. Simultaneously, the support plate 504 slides downwards along the guide plate 502 and the second guide rod 503, ensuring stability during the overall movement. Before the support plate 504 slides downwards until its bottom contacts the two limit blocks 506, the two springs 505 return to their initial length. The support plate 504 and the cutting section of the equipment continue to move downwards due to inertia, compressing the springs 505, thus providing a buffering effect. The limit blocks 506, made of rubber, installed at the bottom of the guide plate 502, prevent the support plate 504 and the cutting section from sliding further downwards, providing a buffering effect and demonstrating strong practicality. This effectively retracts the saw blade 704 into the interior space of the cutting machine body 1, preventing damage caused by continued cutting and improving safety. Furthermore, when the pull rod 510 is not pulled... Because the docking block 508 is threadedly connected to the second lead screw 512, rotating the knob 513 can drive the second lead screw 512 to rotate on the load-bearing beam 501. This causes the second lead screw 512 to drive the docking block 508 and the support plate 504 to move upwards. At this time, the support plate 504 drives the second hydraulic rod 603 and the two drive frames 601 to move upwards. The two drive frames 601 then drive the cutting part of the equipment to move upwards, making it easy to adjust the overall height of the second hydraulic rod 603 and the cutting part. This makes operation simple and highly flexible.

[0035] Specifically, such as Figure 4 and Figures 6-8As shown, the height adjustment structure 6 includes two drive frames 601 and two load-bearing bars 602 fixedly connected to the drive frames 601. A drive frame 601 is slidably connected between two third guide rods 507 located on the same side. A second hydraulic rod 603 is provided at the bottom of one of the drive frames 601. The second hydraulic rod 603 is fixedly connected to the support plate 504. The telescopic end of the second hydraulic rod 603 is fixedly connected to an adjacent drive frame 601. The two drive frames 601 are symmetrically arranged, and a cutting structure 7 is installed between the two load-bearing bars 602. Before using the equipment, first... The height of the saw blade 704 is adjusted according to the size of the aluminum alloy profile 4 to be cut. When it is necessary to cut a larger aluminum alloy profile 4, the height of the saw blade 704 needs to be increased. Simply turn on the power of the equipment. At this time, the telescopic end of the second hydraulic rod 603 extends upward, thereby driving the two drive frames 601 to slide upward along the third guide rod 507. The two drive frames 601 drive the two load-bearing bars 602 and the saw blade 704 above them to move upward. This effectively increases the height of the saw blade 704 extending outward on the cutting machine body 1, which is convenient for cutting aluminum alloy profiles 4 of different sizes. The operation is simple and highly flexible.

[0036] Specifically, such as Figure 4 and Figures 6-8As shown, the cutting structure 7 includes a second guide rail 701 and two sliders 702 slidably connected to the second guide rail 701. Each of the two load-bearing bars 602 is fixedly connected to a second guide rail 701. A mounting base 703 is fixedly connected between the four sliders 702. A third motor 705 is fixedly connected to one end of each load-bearing bar 602 away from the second hydraulic rod 603. A third lead screw 706 is fixedly connected to the output shaft of the third motor 705. One end of the third lead screw 706 away from the third motor 705 is connected to an adjacent drive frame 60. A rotating connection is made between the mounting base 703 and the third lead screw 706. A reducer 707 is fixedly connected to the upper surface of the mounting base 703. A third pulley 710 is mounted on one end of the output shaft of the reducer 707, and a saw blade 704 is mounted on the other end. A fourth motor 708 is fixedly connected to the bottom of the mounting base 703. A second pulley 709 is fixedly connected to the output shaft of the fourth motor 708. A second belt 711 is wound between the second pulley 709 and the third pulley 710. The mounting base 703 is in the form of... The U-shaped structure has a radius larger than that of the second pulley 709 than that of the third pulley 710. During the cutting process, the third motor 705, installed at the end of the load-bearing bar 602, drives the third lead screw 706 to rotate. Since the bottom surface of the mounting base 703 is slidably connected to the second guide rail 701 through four sliders 702, and the mounting base 703 is threadedly connected to the third lead screw 706, the third lead screw 706 drives the mounting base 703 to move back and forth along the second guide rail 701. As a result, the mounting base 703 drives the saw blade 704 located above it to move back and forth. The saw blade moves back and forth, thus achieving the purpose of completely cutting the aluminum alloy profile 4. At the same time, during the movement of the mounting base 703, the fourth motor 708 located at its bottom drives the second pulley 709 on the output shaft to rotate. The second pulley 709 drives the third pulley 710 mounted on the reducer 707 to rotate through the second belt 711. Thus, the third pulley 710 drives the shaft of the reducer 707 and the saw blade 704 at the other end of the shaft to rotate. In conjunction with the back and forth movement of the mounting base 703, the cutting of the aluminum alloy profile 4 is completed. The operation is simple and the cutting efficiency is high.

[0037] Specifically, such as Figures 1-3As shown, the conveying structure 2 includes two first guide rails 201 and a slide plate 202 slidably connected between the two first guide rails 201. The upper surface of the cutting machine body 1 is fixedly connected to the first guide rails 201. The bottom of the slide plate 202 is fixedly connected to the connecting plate 203. The outer wall of the cutting machine body 1 is fixedly connected to the first motor 204. The cutting machine body 1 is rotatably connected to the first lead screw 205. The end of the first lead screw 205 is fixedly connected to the output shaft of the first motor 204. The connecting plate 203 is threadedly connected to the first lead screw 205. Two first support frames 206 are fixedly connected to the slide plate 202. The upper surface of the first support frame 206 is fixedly connected to the first... A hydraulic cylinder 208 has a pressure plate 209 fixedly connected to its output shaft. A first guide rod 207 is fixedly connected to both ends of the pressure plate 209. The first guide rod 207 is slidably connected to a first support frame 206. An aluminum alloy profile 4 is provided on the upper surface of the slide plate 202. The bottom surface of the pressure plate 209 abuts against the aluminum alloy profile 4. A mounting plate 210 is fixedly connected to the side of the first support frame 206. A second hydraulic cylinder 211 is fixedly connected to the inner side of the mounting plate 210. A positioning plate 212 is fixedly connected to the output shaft of the second hydraulic cylinder 211. When the aluminum alloy profile 4 on the connecting frame 301 is conveyed to the cutting machine body 1, it is located on the slide plate. The two first support frames 206 on the cutting machine body 1 are located at one end near the connecting frame 301. When the conveying roller 303 drives the front end of the aluminum alloy profile 4 through the two first support frames 206, the first hydraulic cylinder 208 on the first support frame 206 starts to operate. The telescopic end of the first hydraulic cylinder 208 drives the pressure plate 209 to move downward. The first guide rods 207 installed at both ends of the pressure plate 209 slide between the first support frame 206. The setting of the first guide rods 207 enhances the firmness. At the same time, the second hydraulic cylinder 211 on the mounting plate 210 operates simultaneously. The second hydraulic cylinder 211 drives the positioning plate 212 to move forward until both the pressure plate 209 and the positioning plate 212 abut against the aluminum alloy profile. The aluminum alloy profile 4 is effectively clamped and fixed, improving the stability of the aluminum alloy profile 4 during the cutting process. It also facilitates the transport of the aluminum alloy profile 4 during subsequent cutting. After the clamps on the two first support frames 206 clamp the aluminum alloy profile 4, the first motor 204 located on the outer wall of the cutting machine body 1 starts to drive the first lead screw 205 to rotate. Since the connecting plate 203 at the bottom of the slide plate 202 is threadedly connected to the first lead screw 205, the slide plate 202 is driven to move along the first guide rail 201 at the bottom towards the saw blade 704 until the front end of the aluminum alloy profile 4 is transported to the position of the saw blade 704. Then the cutting of the aluminum alloy profile 4 is completed in one go. The operation is simple and highly flexible.

[0038] Specifically, such as Figure 1 , Figure 2 and Figure 5 As shown, the feeding structure 3 includes a connecting frame 301 and a mounting frame 302 fixedly connected to the connecting frame 301. The connecting frame 301 is fixedly connected to the end of the cutting machine body 1. Multiple conveying rollers 303 are rotatably connected to the mounting frame 302. A second motor 304 is fixedly connected to the side wall of the mounting frame 302. One end of the shaft of one of the conveying rollers 303 is fixedly connected to a first pulley 305, and the other end is fixedly connected to the output shaft of the second motor 304. Another first pulley 305 is fixedly connected to the shaft of another conveying roller 303. A first belt is wound between the two first pulleys 305. Belt 306, a plurality of guide frames 308 are fixedly connected to one end of the connecting frame 301 near the mounting frame 302, and a bracket 307 is fixedly connected to the other end of the connecting frame 301. An aluminum alloy profile 4 abuts against the bracket 307. A first hydraulic rod 309 is fixedly connected to the bottom surface of the connecting frame 301, and a push plate 310 is fixedly connected to the telescopic end of the first hydraulic rod 309. The push plate 310 and the bracket 307 are slidably connected. During the process of conveying the aluminum alloy profile 4 onto the cutting machine body 1, the entire bundle of aluminum alloy profiles 4 is first transported to the brackets 307, so that multiple aluminum alloy profiles 4 are regularly stacked on the brackets 307. Due to the size limitations of the mounting frame 302 and the conveyor roller 303, the number of single-layer aluminum alloy profiles 4 on the bracket 307 is set. When the power to the equipment is turned on, the first hydraulic rod 309 located at the bottom of the connecting frame 301 begins to operate. The telescopic end of the first hydraulic rod 309 drives the push plate 310 to move towards the mounting frame 302. At this time, the push plate 310 pushes the bottommost aluminum alloy profile 4 towards the mounting frame 302. Simultaneously, because multiple guide frames 308 are fixedly connected to the connecting frame 301 near the mounting frame 302, this prevents the upper aluminum alloy profiles 4 from shifting or deviating when pushing the bottommost aluminum alloy profile 4. The bottom aluminum alloy profile 4 is pushed completely between multiple conveyor rollers 303. At this time, the second motor 304 on the mounting frame 302 drives one of the conveyor rollers 303 to rotate. This conveyor roller 303 drives the first pulley 305 on the rotating shaft to rotate. The first pulley 305 drives another first pulley 305 on the other conveyor roller 303 to rotate through the first belt 306. At this time, the two conveyor rollers 303 cooperate with each other to move the aluminum alloy profile 4 onto the cutting machine body 1. This completes the automatic feeding of the aluminum alloy profile 4, avoiding the need for manual alignment of the aluminum alloy profile 4 with the clamps on the cutting machine body 1, and improving the operating efficiency.

[0039] In use, before operating the equipment, the height of the saw blade 704 is adjusted according to the size of the aluminum alloy profile 4 to be cut. When cutting a larger aluminum alloy profile 4, the height of the saw blade 704 needs to be increased. Simply turn on the power to the equipment. At this time, the telescopic end of the second hydraulic rod 603 extends upward, thereby driving the two drive frames 601 to slide upward along the third guide rod 507. The two drive frames 601 drive the two load-bearing bars 602 and the saw blade 704 above them to move upward. This effectively increases the height of the saw blade 704 extending outward on the cutting machine body 1, making it easier to cut aluminum alloy profiles 4 of different sizes. The operation is simple and highly flexible. During the cutting process, the third motor 705 installed at the end of the load-bearing bar 602 drives the third lead screw 706 to rotate. Since the bottom surface of the mounting base 703 is connected by four sliders 7 The mounting base 703 is slidably connected to the second guide rail 701, and the mounting base 703 is threadedly connected to the third lead screw 706. The third lead screw 706 drives the mounting base 703 to move back and forth along the second guide rail 701, thereby driving the saw blade 704 located above it to move back and forth, thus achieving the purpose of completely cutting the aluminum alloy profile 4. At the same time, during the movement of the mounting base 703, the fourth motor 708 located at its bottom drives the second pulley 709 on the output shaft to rotate. The second pulley 709 drives the third pulley 710 mounted on the reducer 707 to rotate through the second belt 711. Thus, the third pulley 710 drives the shaft of the reducer 707 and the saw blade 704 at the other end of the shaft to rotate, which, together with the back and forth movement of the mounting base 703, completes the cutting of the aluminum alloy profile 4. The operation is simple and the cutting efficiency is high.

[0040] During the cutting process, if abnormal phenomena such as the saw blade 704 being stuck by the aluminum alloy profile 4 or experiencing excessive resistance are found, in order to avoid damage to the saw blade 704 or fragments flying in all directions, simply pull the pull rod 510 on the side of the cutting machine body 1. The pull rod 510 will then drive the two locking blocks 509 inside the connecting block 508 to slide outwards. At the same time, one of the locking blocks 509 compresses the spring 511 until the two locking blocks 509 are no longer engaged with the groove on the support plate 504. At this time, the support plate 504 and the mounting plate 508 will be properly secured. The cutting section mounted above moves rapidly downwards under the force of gravity and the tension of the spring 505, causing the saw blade 704 to move rapidly downwards until it is completely retracted into the interior of the cutting machine body 1. Simultaneously, the support plate 504 slides downwards along the guide plate 502 and the second guide rod 503, ensuring stability during the overall movement. Before the support plate 504 slides downwards until its bottom contacts the two limit blocks 506, the two springs 505 return to their initial length. The support plate 504 and the cutting section of the equipment continue to move downwards due to inertia, compressing the springs 505, thus providing a buffering effect. The limit blocks 506, made of rubber, installed at the bottom of the guide plate 502, prevent the support plate 504 and the cutting section from sliding further downwards, providing a buffering effect and demonstrating strong practicality. This effectively retracts the saw blade 704 into the interior space of the cutting machine body 1, preventing damage caused by continued cutting and improving safety. Furthermore, when the pull rod 510 is not pulled... Since the docking block 508 is threadedly connected to the second lead screw 512, the second lead screw 512 can be rotated on the load-bearing beam 501 by rotating the knob 513. Thus, the second lead screw 512 drives the docking block 508 and the support plate 504 to move upward. At this time, the support plate 504 drives the second hydraulic rod 603 and the two drive frames 601 to move upward. The two drive frames 601 drive the cutting part of the equipment to move upward, which makes it easy to adjust the overall height of the second hydraulic rod 603 and the cutting part. The operation is simple and highly flexible.

[0041] During the process of feeding aluminum alloy profiles 4 onto the cutting machine body 1, the entire bundle of aluminum alloy profiles 4 is first transported to the brackets 307, so that multiple aluminum alloy profiles 4 are regularly stacked on the brackets 307. Due to the size limitations of the mounting frame 302 and the conveying roller 303, the number of aluminum alloy profiles 4 per layer on the brackets 307 is set. At this time, the power of the equipment is turned on, and then the first hydraulic rod 309 located at the bottom of the connecting frame 301 starts to operate. The telescopic end of the first hydraulic rod 309 drives the push plate 310 to move towards the mounting frame 302. At this time, the push plate 310 pushes the bottom layer of aluminum alloy profiles 4 towards the mounting frame 302. At the same time, since multiple guide frames 308 are fixedly connected to the connecting frame 301 near the mounting frame 302, this avoids... When pushing the bottom aluminum alloy profile 4, the upper aluminum alloy profile 4 is displaced or shifted, and the bottom aluminum alloy profile 4 is completely pushed between multiple conveying rollers 303. At this time, the second motor 304 on the mounting frame 302 drives one of the conveying rollers 303 to rotate. The conveying roller 303 drives the first pulley 305 on the rotating shaft to rotate. The first pulley 305 drives another first pulley 305 on the other conveying roller 303 to rotate through the first belt 306. At this time, the two conveying rollers 303 cooperate to move the aluminum alloy profile 4 onto the cutting machine body 1. At this time, the automatic feeding of the aluminum alloy profile 4 is completed, avoiding the need for manual alignment of the aluminum alloy profile 4 with the clamps on the cutting machine body 1, and improving the operating efficiency.

[0042] During the process of conveying the aluminum alloy profile 4 on the connecting frame 301 to the cutting machine body 1, the two first support frames 206 located on the slide plate 202 are located at the end of the cutting machine body 1 near the connecting frame 301. After the conveying roller 303 drives the front end of the aluminum alloy profile 4 through the two first support frames 206, the first hydraulic cylinder 208 located on the first support frame 206 starts to operate. The telescopic end of the first hydraulic cylinder 208 drives the pressure plate 209 to move downward. The first guide rods 207 installed at both ends of the pressure plate 209 slide between the first support frame 206. The setting of the first guide rods 207 enhances the firmness. At the same time, the second hydraulic cylinder 211 located on the mounting plate 210 operates simultaneously. The second hydraulic cylinder 211 drives the positioning plate 212 to move forward until the pressure plate 212 is pressed down. Both plate 209 and positioning plate 212 abut against the aluminum alloy profile 4, effectively clamping and fixing the aluminum alloy profile 4, improving the stability of the aluminum alloy profile 4 during the cutting process, and facilitating the subsequent conveying of the aluminum alloy profile 4 during the cutting process. After the clamps on the two first support frames 206 clamp the aluminum alloy profile 4, the first motor 204 located on the outer wall of the cutting machine body 1 starts to drive the first lead screw 205 to rotate. Since the connecting plate 203 at the bottom of the slide plate 202 is threadedly connected to the first lead screw 205, the slide plate 202 is driven to move along the first guide rail 201 at the bottom towards the saw blade 704 until the front end of the aluminum alloy profile 4 is conveyed to the position of the saw blade 704, and then the cutting of the aluminum alloy profile 4 is completed in one go. The operation is simple and highly flexible.
