Description

Technical Field

[0001] This invention relates to the field of metal processing equipment technology, specifically to a feeding mechanism for an adjustable-speed metal circular saw. Background Technology

[0002] In the metal processing industry, metal circular saws are widely used for cutting metal workpieces such as pipes and profiles due to their high cutting efficiency and smooth cuts. As the core component of the metal circular saw, the feeding mechanism is responsible for conveying and positioning the workpiece. Its operational stability, adaptability, and speed adjustment flexibility are directly related to the workpiece cutting accuracy, processing efficiency, and equipment lifespan, and are a key link in ensuring the processing performance of the metal circular saw.

[0003] Currently, the feeding mechanisms of metal circular saws on the market generally suffer from poor workpiece positioning and support adaptability. Traditional mechanisms mostly use rigid clamping or fixed baffle structures, which not only easily damage the workpiece surface during clamping but also make it difficult to flexibly adjust the clamping distance and support height according to different workpiece specifications, resulting in insufficient versatility. For metal workpieces of different diameters and lengths, it is necessary to replace the appropriate feeding components, increasing processing costs and operational complexity. At the same time, rigid contact easily increases the workpiece conveying resistance, causing conveying jams and affecting processing continuity. Secondly, the speed of existing feeding mechanisms is mostly directly determined by the motor speed. If the speed needs to be adjusted, it is often necessary to stop the machine to replace the motor, add a frequency converter, or adjust the transmission ratio. The operation is complicated and cannot achieve stepless speed regulation, making it difficult to accurately adapt to the cutting process requirements of different materials (such as carbon steel, stainless steel, aluminum alloy, etc.). In addition, the lack of precise guiding structures for each component makes it easy to deviate during operation, resulting in decreased feeding accuracy, increased equipment failure rate, and affecting the stability and reliability of processing.

[0004] Therefore, there is an urgent need for a feeding mechanism for metal circular saws that can flexibly adapt to workpieces of different specifications, achieve stepless speed regulation, and operate stably and reliably. Summary of the Invention

[0040] Example 1:

[0041] like Figures 1 to 6 As shown in the figure, the adjustable speed feeding mechanism for a metal circular saw provided in this embodiment includes: a base plate 1, a support plate 2 disposed above the base plate 1, and the lower surface of the support plate 2 and the upper surface of the base plate 1 connected by columns, the columns being disposed at the four corners of the base plate 1 and the support plate 2, a stabilizing component 3 disposed on one side of the upper surface of the support plate 2 for stabilizing support on one side of the workpiece, and a support component 4 disposed on the side of the upper surface of the support plate 2 away from the stabilizing component 3 for supporting the other side of the workpiece, a lifting component 6 disposed between the base plate 1 and the support plate 2 for lifting the workpiece during movement, and a speed regulating component 5 disposed at the end of the upper surface of the base plate 1 near the support component 4 for adjusting the conveying speed.

[0042] In this embodiment, the stabilizing component 3, the supporting component 4, the speed regulating component 5, and the lifting component 6 constitute a feeding mechanism for an adjustable-speed metal circular saw according to this application.

[0043] It should also be noted that the metal circular saw in this application can be a fully automatic metal circular saw, a semi-automatic metal circular saw, a manual metal circular saw, etc. Figure 1 In this embodiment, a fully automatic metal circular saw is used as an example for description. Of course, other types of metal circular saws can also adopt a similar structure, which will not be described in detail below.

[0044] Understandable, Figure 1 The diagram only schematically illustrates some of the components of the adjustable speed feeding mechanism; the actual shape, size, position, and construction of these components are not subject to change. Figure 1 Due to limitations, adjustable speed feeding mechanisms can also include those that are more advanced than... Figure 1 More or fewer parts.

[0045] Furthermore, in this embodiment, the workpiece is positioned on both sides by the stabilizing component 3 and the supporting component 4, the lifting component 6 lifts the workpiece, and the speed regulating component 5 adjusts the conveying speed, so as to achieve stable conveying of the workpiece and adjustable speed, ensuring the basic processing requirements.

[0046] Specifically, the stabilizing component 3 includes a stabilizing plate 301, which is disposed on one side of the upper surface of the support plate 2. The middle of one side of the stabilizing plate 301 is connected to the telescopic end of the hydraulic rod 302. The fixed end of the hydraulic rod 302 is connected to the upper surface of the support plate 2 through a bracket. First guide rods 303 are provided on both sides of the hydraulic rod 302.

[0047] In this embodiment, the hydraulic rod 302 extends and retracts to drive the stabilizing plate 301 to move, and the first guide rod 303 assists in guiding, so as to realize the precise movement of the stabilizing plate 301 and provide power for workpiece positioning.

[0048] Specifically, one end of the first guide rod 303 is connected to the side wall of the stabilizing plate 301, and the side of the first guide rod 303 away from the stabilizing plate 301 is connected to the upper surface of the support plate 2 through a bracket. The first guide rod 303 slides in the bracket. The two ends of the stabilizing plate 301 near the hydraulic rod 302 are connected to one end of the stabilizing support plate 304. The end of the stabilizing support plate 304 away from the stabilizing plate 301 passes through the support plate 2, and the lower part of the stabilizing support plate 304 slides in the support plate 2.

[0049] In this embodiment, when the stabilizing plate 301 moves, it drives the first guide rod 303 to slide along the bracket and the stabilizing support plate 304 to slide along the support plate 2, thereby improving the stability of the stabilizing plate 301 and preventing deviation.

[0050] Example 2:

[0051] A support component 4 is provided based on embodiment 1.

[0052] Specifically, the support component 4 includes a side plate 401, which is placed on the upper surface of the support plate 2 away from the stabilizing component 3. The two ends of the side plate 401 away from the stabilizing plate 301 are connected to the upper ends of the support arm 402, and the end of the support arm 402 away from the side plate 401 is connected to the upper surface of the support plate 2.

[0053] In this embodiment, the side plate 401 is fixed at a designated position on the support plate 2 by the support arm 402, and together with the stabilizing component 3, a support and positioning structure for both sides of the workpiece is formed.

[0054] Specifically, a plurality of balls 7 are provided on the side wall of the stabilizing plate 301 near the side plate 401, and the balls 7 are evenly arranged along the side wall of the stabilizing plate 301. Three sets of rollers 8 are evenly arranged along the length of the stabilizing plate 301 on the side of the side plate 401 away from the stabilizing plate 301, and one side of the rollers 8 penetrates through the side plate 401.

[0055] In this embodiment, when the workpiece is positioned, the ball 7 and the roller 8 contact the two sides of the workpiece respectively, converting the sliding friction between the workpiece and the assembly into rolling friction, reducing the conveying resistance and avoiding damage to the workpiece surface.

[0056] Specifically, the lower surface of the roller 8 is rotatably connected to one end of the support rod 602, and the lower ends of the two sets of roller 8 support rods 602 on the side of the roller 8 away from the speed regulating component 5 pass through the support plate 2 and are connected to the upper surface of the base plate 1.

[0057] In this embodiment, the support rod 602 provides support for the roller 8, ensuring the stable rotation of the roller 8 and ensuring stable operation of the roller 8 when bearing the weight of the workpiece, thus providing basic support for workpiece conveying.

[0058] Example 3:

[0059] A speed regulating component 5 is provided based on embodiment 2.

[0060] Specifically, the speed control assembly 5 includes a speed control box 501, which is mounted on the upper surface of the base plate 1. A motor 502 is installed inside the speed control box 501 on one side. The output shaft of the motor 502 is connected to one end of a transmission shaft 503. The side of the speed control box 501 away from the motor 502 is connected to one end of another set of transmission shafts 503. The end of the transmission shaft 503 away from the motor 502 is connected to the lower surface of a rotating disk 505. The rotating disk 505 has an I-shaped cross-section and multiple sliding grooves are arranged in a ring shape above and below the rotating disk 505. The two ends of the adjusting block 506 are slidably connected in the sliding grooves.

[0061] In this embodiment, there are two drive shafts 503, located on both sides inside the speed control box 501. The motor 502 drives the drive shafts 503 to rotate, which in turn drives the rotating disk 505 to rotate. The adjusting block 506 slides along the slide groove, providing a basic structure for speed regulation and power transmission, and realizing the initial power transmission.

[0062] Specifically, the two sets of rotating disks 505 are connected by a belt 507, and the inner wall of the belt 507 is evenly provided with multiple toothed grooves, which mesh with the outer wall of the adjusting block 506. The drive shaft 503 is keyed to the sliding cylinder, and the outer wall of the sliding cylinder is rotatably connected to the rotating ring 504. Multiple linkage rods 508 are arranged in a ring above the sliding cylinder, and the upper end of the sliding cylinder is hinged to one end of the linkage rod 508. The end of the linkage rod 508 away from the sliding cylinder is respectively hinged to the lower end of the multiple adjusting blocks 506.

[0063] In this embodiment, a rotating disk 505 drives the belt 507 to move via the adjusting block 506, and the belt 507 drives the other rotating disk 505 to rotate. The sliding cylinder rises and falls, driving the linkage rod 508 to drive the adjusting block 506 to slide, thereby realizing power transmission and providing an adjustment structure for speed regulation.

[0064] Specifically, an adjustment plate 509 is provided between the rotating rings 504, and the two ends of the adjustment plate 509 are rotatably connected to the side walls of the rotating rings 504 respectively. The side wall of the adjustment plate 509 away from the motor 502 is rotatably connected to the telescopic end of the electric telescopic rod 510. A rotating shaft is provided in the middle of the adjustment plate 509, and the two ends of the rotating shaft are connected to the inner wall of the speed control box 501 respectively. The fixed end of the electric telescopic rod 510 is hinged to the inner bottom surface of the speed control box 501. The upper surface of the rotating disk 505 away from the motor 502 is connected to the lower end of the support column of the roller 8.

[0065] In this embodiment, the electric telescopic rod 510 drives the adjustment plate 509 to rotate around the rotating shaft, which drives the rotating ring 504 to move along the transmission shaft 503. Then, the position of the adjustment block 506 is adjusted through the sliding cylinder and the linkage rod 508. The rotating disk 505 rotates and drives the roller 8 to rotate, thereby realizing the adjustment of the feeding speed. At the same time, the power of the speed adjustment component is transmitted to the roller 8 to drive the workpiece conveying.

[0066] Specifically, the lifting assembly 6 includes a lifting plate 601. Two sets of lifting plates 601 are provided, and the lifting plates 601 are placed on both sides of the upper surface of the support plate 2. The lower surface of the lifting plate 601 is connected to the upper ends of both sides of the support rod 602. The lower end of the support rod 602 is threadedly connected to the screw 603. One end of the screw 603 is rotatably connected to the upper surface of the base plate 1, and the end of the screw 603 away from the base plate 1 passes through the support plate 2. The lower end of the support rod 602 away from the screw 603 slides on the second guide rod 604, and the two ends of the second guide rod 604 are respectively connected to the upper surface of the base plate 1 and the lower surface of the support plate 2.

[0067] In this embodiment, the rotating screw 603 drives the support rod 602 to rise and fall along the second guide rod 604, thereby driving the lifting plate 601 to rise and fall, realizing the adjustment of the workpiece lifting height to adapt to workpieces of different specifications.

[0068] In actual use, the workpiece to be cut is first placed on the upper surface of the lifting plate 601 in the lifting assembly 6. Then, the upper end of the screw 603 is rotated. The rotation of the screw 603 drives the threaded support rod 602 to move. The movement of the support rod 602 pushes the lifting plate 601 and the workpiece to move upward. At this time, the end of the support rod 602 away from the screw 603 slides on the second guide rod 604.

[0069] After adjusting the workpiece to a suitable height, the hydraulic rod 302 is activated. The telescopic end of the hydraulic rod 302 pushes the stabilizing plate 301 to move. While the stabilizing plate 301 moves, the first guide rods 303 connected to both sides of the stabilizing plate 301 slide along the top of the bracket, and the stabilizing support plate 304 connected to the side wall of the stabilizing plate 301 slides along the inside of the support plate 2. Then, the side wall of the stabilizing plate 301 is moved to one side of the workpiece. At this time, the multiple sets of balls 7 set on the side wall of the stabilizing plate 301 abut against the side wall of the workpiece, and the other side wall of the workpiece abuts against one side of the roller 8 in the side wall of the side plate 401.

[0070] After the workpiece is clamped, the motor 502 is started. The output shaft of the motor 502 drives the transmission shaft 503 to rotate. The rotation of the transmission shaft 503 drives a set of rotating disks 505 to rotate. Since the two sets of rotating disks 505 are connected by a belt 507, one set of rotating disks 505 drives the belt 507 to move through the adjusting block 506. The belt 507 drives the other set of rotating disks 505 to rotate. The rotation of the other set of rotating disks 505 drives the support rod 602 of the roller 8 to rotate. The rotation of the roller 8 drives the workpiece to move. At this time, the rollers 8 and balls 7 on both sides of the workpiece are used for the smooth movement of the workpiece.

[0071] If speed adjustment is required, the electric telescopic rod 510 is activated. The telescopic end of the electric telescopic rod 510 drives one end of the adjusting plate 509 to rise or fall. The adjusting plate 509 rotates along the central pivot, causing the end of the adjusting plate 509 away from the electric telescopic rod 510 to rise or fall in the opposite direction. The rise or fall of the adjusting plate 509 drives the rotating ring 504 to move along the transmission shaft 503. The movement of the rotating ring 504 drives the sliding cylinder to rise and fall. The keyed connection between the sliding cylinder and the transmission shaft 503 allows the sliding cylinder to rotate while simultaneously moving forward. The sliding cylinder is raised and lowered, and the outer wall of the sliding cylinder is rotatably connected to the rotating ring 504 to prevent the rotating ring 504 from rotating. As the sliding cylinder rises and falls, the sliding cylinder drives the linkage rod 508 to rise and fall. Since the two ends of the linkage rod 508 are respectively hinged to the sliding cylinder and the adjusting block 506, the rise and fall of the linkage rod 508 drives the adjusting block 506 to slide along the slide groove on a set of rotating disks 505, and drives the adjusting block 506 on another set of rotating disks 505 to slide in the opposite direction, thereby adjusting the diameter of the two ends of the belt 507, thereby adjusting the speed of the roller 8.

[0072] Hydraulic rod 302, motor 502 and electric telescopic rod 510 are all electrically connected to the controller, which is electrically connected to an external power supply. The controller facilitates the power supply control of electrical equipment, allowing the equipment to be powered on when needed, thus avoiding the situation where power cannot be supplied when needed.

[0073] It should be noted that the controller can be a conventional known device that is controlled by a computer or other means. The detailed description of known functions and known components is omitted in the specific embodiments of this disclosure. In order to ensure the compatibility of the device, the operating methods used are consistent with the parameters of commercially available instruments.
