Description

Technical Field

[0001] This invention relates to the field of sawing technology, and more particularly to a sawing machine for continuously sawing workpieces. Background Technology

[0002] Currently, the mainstream process for mass production of long threaded rods in the industry is full-length thread rolling followed by segmented cutting and forming. This involves first performing thread rolling on the entire long round steel bar to produce a long threaded rod with threads along its entire length. Then, according to the required length of the product, the long threaded rod is cut into segments to obtain the finished threaded rod of the standard length. This process has the advantages of good thread continuity, no broken tooth defects, and high efficiency in mass production, and is widely used in the mass production of various long and short threaded rods.

[0003] In the existing production process, the toothed bars after full-length tooth rolling are usually bundled and stacked for sawing. However, in actual production, the bundled long toothed bars generally have uneven ends, which cannot directly meet the precise alignment and cutting requirements of the slitting equipment. To ensure that each toothed bar is cut to a uniform size and with a precise cut position, the ends of the toothed bars need to be aligned and corrected before bundling.

[0004] However, in manual alignment, thread engagement jamming makes alignment difficult and cumbersome, requires high operator skill, and takes a long time for each alignment operation, which seriously reduces the overall processing efficiency of the toothed bar cutting process. Manual alignment by rotating and hammering is inconvenient and can easily cause damage to the toothed bar threads and slight bending deformation of the bar body. This not only affects the appearance quality and thread accuracy of the finished toothed bar, but also leads to problems such as poor engagement and insufficient fastening accuracy during subsequent assembly and use. At the same time, manual alignment is labor-intensive and costly. Therefore, a sawing machine for continuous sawing of workpieces is proposed. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of the prior art by proposing a sawing machine for continuously cutting workpieces.

[0018] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0019] like Figures 1-10The image shows a saw for continuously cutting workpieces, comprising a main body 1. A clamp 41 is mounted on the upper surface of the main body 1; the clamp 41 is a vise-type clamp commonly used in the art and is a readily available standard component. A lifting frame 2 is mounted on the upper surface of the main body 1 via a lifting mechanism. A saw blade 34 is mounted on the inner side of the lifting frame 2 via a drive mechanism, and the saw blade 34 is located above and in front of the clamp 41. A receiving plate 5 is fixedly mounted at the rear of the main body 1. A baffle 6 is mounted on the rear surface of the main body 1 via a lifting mechanism. A connecting plate 7 is fixedly connected to the upper end of the baffle 6. A contact plate 9 is slidably connected to the rear surface of the connecting plate 7 in the front-rear direction via a first elastic mechanism. The rear surface of the connecting plate 7 has openings on both sides... A sliding block 17 is slidably connected laterally via a second elastic mechanism. An insert block 18 is fixedly connected to the front end of the sliding block 17. An insertion port 20 is opened at each of the two corners of the front surface of the contact plate 9. The insert block 18 is slidably inserted into the inside of the insertion port 20. An inclined guide surface 19 is opened on the side of the two insert blocks 18 that are close to each other. A connecting arm 21 is fixedly connected to the lower end of the sliding block 17. A support plate 22 is connected to the side of the two connecting arms 21 that are close to each other via a locking mechanism. The lower ends of the two support plates 22 are inserted into each other. The front end of the dental rod moves forward along the surface of the two support plates 22. After the front end of the dental rod pushes the contact plate 9, the insert block 18 is disengaged from the inside of the insertion port 20. Then, under the gravity of the dental rod, it pushes open the two support plates 22 and falls down.

[0020] The lifting mechanism includes a lifting cylinder 3 fixedly installed at the front end of the upper surface of the device body 1. The telescopic end of the lifting cylinder 3 is fixedly connected to the lifting frame 2. One side of the lower surface of the lifting frame 2 is vertically slidably engaged with the device body 1. The bottom of the lifting frame 2 and the upper surface of the device body 1 are respectively fixedly installed with vertical slide rails. The two vertical slide rails are vertically slidably engaged. The upper surface of the device body 1 is slidably inserted. A support frame 4 is fixedly installed in the middle of the rear surface of the device body 1. The lower surface of the receiving plate 5 is fixedly connected to the upper end of the support frame 4. The support frame 4 stabilizes the receiving plate 5 at the working height.

[0021] The drive mechanism includes drive wheels 35 rotatably mounted inside the lifting frame 2. The saw blade 34 is fitted onto the surface of the two drive wheels 35. One set of drive wheels 35 is externally connected to a drive motor and gearbox, generating power to rotate the drive wheels 35 to cyclically pull the saw blade 34 for cutting. This is a common drive scheme in the prior art, so it will not be described in detail. Two guide seats 36 are fixedly installed inside the lifting frame 2. The lower edge of the saw blade 34 passes through the lower ends of the two guide seats 36. Wear-resistant guide bushings are embedded inside the guide seats 36 to constrain the lateral displacement of the saw blade 34.

[0022] The lifting mechanism includes a lifting cylinder 37 fixedly installed on one side of the rear surface of the main body 1. The telescopic end of the lifting cylinder 37 is fixedly connected to the lower surface of the baffle 6. A stabilizing rod 38 is fixedly connected to the lower surface of the baffle 6. A stabilizing plate 39 is fixedly connected to the edge of the rear surface of the main body 1. The stabilizing rod 38 slides through the inner side of the stabilizing plate 39 to limit and guide the lifting of the baffle 6, effectively counteracting lateral forces and preventing deviation and swaying. Triangular plates 40 are fixedly installed on both sides of the rear surface of the baffle 6. The triangular plates 40 guide the front end of the dental rod into the surface of the two support plates 22.

[0023] The first elastic mechanism includes several first guide posts 10 fixedly connected to the rear surface of the connecting plate 7. The rear ends of the several first guide posts 10 are fixedly connected to a first end plate 11. The first end plate 11 can prevent the touch plate 9 from sliding backward and dislodging from the first guide post 10. The touch plate 9 is slidably sleeved on the outer surface of the first guide post 10. A first compression spring 12 is sleeved on the outer surface of one of the first guide posts 10. The two ends of the first compression spring 12 are fixedly connected to the touch plate 9 and the outer surface of the connecting plate 7, respectively. A recess 8 is provided on the rear surface of the baffle 6 corresponding to the rear of the touch plate 9. The recess 8 provides space for the touch plate 9 to move forward. After the touch plate 9 moves forward, the rear surface of the touch plate 9 is flush with the rear surface of the baffle 6. When the front end of the toothed rod falls, it can ensure that the front end of the toothed rod abuts against the rear surface of the baffle 6, which is conducive to the alignment of the toothed rod.

[0024] The second elastic mechanism includes a fixing block 13 fixedly connected to the rear surface of the connecting plate 7. Several second guide posts 14 are fixedly connected to one side surface of the fixing block 13. One end of each of the second guide posts 14 is fixedly connected to a second end plate 15. The second guide posts 14 slide through the inner side of the sliding block 17. A second compression spring 16 is sleeved on the outer surface of one of the second guide posts 14. The two ends of the second compression spring 16 are fixedly connected to the outer surfaces of the sliding block 17 and the fixing block 13, respectively. The second end plate 15 prevents the sliding block 17 from shifting laterally and disengaging from the second guide post 14. The elastic force of the first compression spring 12 must be less than the pushing force caused by the weight of the toothed rod, and less than the pushing force exerted by the second compression spring 16 on the contact plate 9 through the sliding block 17 and the inclined guide surface 19 when the second compression spring 16 is reset, ensuring that the toothed rod can smoothly press the contact plate 9 backward and that the sliding block 17 can normally push the contact plate 9 to reset.

[0025] The locking mechanism includes a rotating plate 23 fixedly connected to one side surface of the support plate 22. A rotating column 24 is fixedly connected to one side surface of the rotating plate 23. The rotating column 24 slides through one side surface of the connecting arm 21. A positioning ring 25 is slidably fitted onto the outer surface of the rotating column 24 along the axial direction. The positioning ring 25 and the rotating plate 23 are located on opposite sides of the connecting arm 21. A limiting tooth 26 is provided on the side of the positioning ring 25 closest to the connecting arm 21. A toothed groove 30 is formed on one side surface of the connecting arm 21. The limiting tooth 26 meshes with the toothed groove 30. A locking nut 29 is threaded onto one end of the rotating column 24. Tightening the locking nut 29 will press the positioning ring 25, locking the relative angle between the rotating column 24 and the connecting arm 21, thus fixing and locking the tilt angle of the support plate 22, adapting to the placement and guiding requirements of different specifications of dental rods.

[0026] A key bar 27 is fixedly provided on the inner wall of the positioning ring 25, and a keyway 28 extending axially is provided on the outer surface of the rotating column 24. The key bar 27 slides into the inner side of the keyway 28, so that the positioning ring 25 can slide freely along the axial direction of the rotating column 24, and the positioning ring 25 can rotate synchronously with the rotating column 24.

[0027] An extension 31 is fixedly provided at the lower end of the tray 22. The two extensions 31 are respectively provided with a protrusion 32 and a groove 33 on their adjacent sides. The protrusion 32 slides into the inner side of the groove 33. This constrains the two trays 22 to only be able to separate or fit together horizontally at the same time, preventing the trays 22 from being misaligned or tilted on one side.

[0028] The operator guides the tip of the dental bar through the triangular plate 40 to the surface of the two support plates 22. The dental bar tilts and slides forward in accordance with the tilt of the two support plates 22. When it slides into contact with the contact plate 9, the contact plate 9 is pushed forward and downward, squeezing the first compression spring 12. The contact plate 9 is squeezed into the recess 8. At this time, the insert 18 is completely disengaged from the insert 20. Then, under the combined action of the large torque at the tip of the dental bar and its own weight, the two support plates 22 are pushed apart to the sides, causing the dental bar to fall naturally. The dental bar falls naturally onto the surface of the receiving plate 5, and the tip of the dental bar will abut against the rear surface of the baffle 6. The dental bars are placed in sequence according to the above operation. Several dental bars will be neatly stacked on the surface of the receiving plate 5. Several dental bars can be neatly stacked on the receiving plate 5. The tips of all dental bars are kept flat. There is no need to use the existing technology of rotating, hammering and prying to align and correct the tips of the dental bars, which simplifies the subsequent processing procedures.

[0029] After the dental rod falls, driven by the elastic force of the second compression spring 16, the two sliding blocks 17 move closer together. The inclined guide surface 19 of the sliding block 17 abuts against the edge of the contact plate 9 and pushes it slightly forward. This slight displacement will not hinder the sliding block 17 from continuing to move. When the sliding block 17 moves to the second end plate 15 and is stopped, the rebound force of the first compression spring 12 drives the contact plate 9 to reset backward. The insertion block 18 then gets stuck into the insertion port 20. At this time, the two support plates 22 are pressed together and reset, ensuring that they can play a normal guiding role for the subsequent dental rods.

[0030] After several teeth bars are stacked, the lifting cylinder 37 extends, causing the baffle 6, support plate 22 and triangular plate 40 to move upward away from the vicinity of the teeth bars. Then, the operator performs a binding operation on the front and rear ends of the teeth bars, so that the teeth bars are bundled and pushed forward into the clamp 41. After the clamp 41 clamps the teeth bars, the lifting cylinder 3 moves downward, and the drive wheel 35 drives the saw blade 34 to continuously cut several teeth bars, ensuring that the ends are neat and the cutting efficiency is high.

[0031] After the operator positions and fixes the pallet 22, loosening the locking nut 29 allows the positioning ring 25 to move away from the connecting arm 21. The key bar 27 slides along the inside of the keyway 28, and the limiting tooth 26 disengages from the tooth groove 30. Then, the rotating plate 23 and the pallet 22 can rotate simultaneously. Because the protrusion 32 is embedded in the strip groove 33, after loosening the locking nut 29 on the other side, the two pallets 22 can rotate synchronously, ensuring that the tilt angle of the two pallets 22 is uniform. After adjusting to the required tilt angle, tightening the locking nut 29 completes the locking. The tilt angle of the pallet 22 can be flexibly adjusted to adapt to the tilt posture of the feed bar: it can avoid the tilt angle being too small, which would prevent the feed bar from sliding forward and downward smoothly, and it can also prevent the tilt angle from being too large, which would cause the tail of the feed bar to fall too high and be damaged by excessive impact force.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
