Description

Technical Field

[0001] This utility model relates to the technical field of vertical band saws, specifically a continuous feeding vertical band saw. Background Technology

[0002] In the metal processing field, band saws, as key equipment, are widely used in numerous industries such as steel, machinery, automotive, shipbuilding, petroleum, mining, and aerospace, undertaking the important task of sawing metal materials. The sawing process not only effectively saves materials and reduces the workload of subsequent secondary processing, but also significantly improves production efficiency, making it an indispensable part of the parts processing flow. Among various types of band saws, vertical band saws, with their unique structure and working method, play a crucial role in processing specific materials.

[0003] Cylindrical bars are commonly used raw materials in the machinery industry, used to process components such as bearings, shafts, and piston rods. However, processing cylindrical bars as incoming materials is quite challenging in the machinery field. Because it's difficult to automatically feed and hold cylindrical bars when using a vertical band saw, manual feeding and fixing of the workpiece are usually required, resulting in extremely low efficiency.

[0004] Reference patent (publication number: CN218983403U; publication date: 2023-05-09) discloses a continuous feeding vertical band saw specifically for sawing cylindrical bars. The upper surface of the saw body is equipped with a stepping worktable capable of reciprocating laterally along the saw body. The upper surface of the stepping worktable has grooves for limiting the cylindrical bars to be processed. A support is fixedly installed on the inner or outer side of the stepping worktable, and a clamping cylinder for clamping and fixing the bars to be processed is fixedly installed on the support. A feeding mechanism is fixedly installed on one side of the saw body at the starting point of the stepping worktable. The feeding mechanism includes a base, and a material platform with an inclined top surface is fixedly installed on the top of the base. A gap is provided between the material platform and the saw body. The vertical band saw also includes a lifting cylinder disposed in the gap between the material platform and the saw body for lifting the cylindrical bars to be processed.

[0005] Based on the aforementioned patent, the bar feed is achieved by relying on the tilt angle and gravity of the feed table. However, during the feeding process, due to the lack of sequential limiting and blocking effects, multiple bars are prone to continuous rolling and overfeeding during gravity feeding. At the same time, some vertical band saws with automatic feeding functions usually lack effective guiding devices, causing cylindrical bars to easily deviate from the predetermined path during the feeding process. Therefore, this utility model provides a continuous feeding vertical band saw. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a continuous feeding vertical band saw, which solves the problem that when feeding bars by relying on the tilt angle and gravity of the table, the lack of sequential limiting and blocking effects during feeding can easily cause multiple bars to roll continuously and be over-fed under gravity. In addition, some vertical band saws with automatic feeding functions usually lack effective guiding devices, which can cause cylindrical bars to deviate from the predetermined path during feeding.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a continuous feeding vertical band saw, comprising a support leg, wherein the support leg is provided with a feeding mechanism for processing by the vertical band saw, the feeding mechanism comprising:

[0008] The limiting component includes a processing platform disposed on the upper end of the support leg. A loading platform is fixed on one side of the processing platform at the upper end face of the support leg. A first inclined surface for loading is formed on the surface of the loading platform. A sliding groove is formed at the top of the loading platform. A limiting bracket connected by an opening and closing component is disposed inside the sliding groove.

[0009] The feeding assembly includes a fixed plate fixed to the inner wall of the support leg, a fixed rod fixed to the upper end face of the fixed plate, a first stop fixed to the top of the fixed rod, a second inclined surface formed on the upper end face of the first stop, a support plate connected by a lifting assembly at the center of the upper end face of the fixed plate, four sets of vertical rods fixed to the upper end face of the support plate, a push block and a second stop fixed to the top of the vertical rods respectively, a third inclined surface formed on the upper end face of the second stop, a feeding inclined block fixed to the upper end of the processing platform near the second stop, and a mounting platform connected by a detachable assembly on the upper end face of the processing platform.

[0010] Preferably, the opening and closing assembly includes a bidirectional lead screw rotatably connected inside the slide groove, a slider bracket slidably connected to the inner wall of the slide groove, a limiting bracket fixedly connected to one end of the slider bracket, two sets of limiting brackets, and the slider bracket and the bidirectional lead screw are threadedly connected.

[0011] Preferably, the inner side of the limiting bracket is evenly distributed with rotatable limiting rollers, and the limiting bracket is slidably connected to the first inclined surface.

[0012] Preferably, the lifting assembly includes a first electric push rod that is fixedly inserted through the interior of a fixed plate, a support plate that is fixedly connected to the telescopic end of the first electric push rod, and the support plate and the fixed rod are slidably connected.

[0015] Beneficial effects

[0016] This utility model provides a continuous feeding vertical band saw. Compared with the prior art, it has the following advantages:

[0017] Beneficial effects:

[0018] Firstly, this utility model utilizes the combination of gravity and the first electric push rod to achieve automatic feeding, greatly improving feeding efficiency, reducing manual operation, and lowering labor intensity. The design of the second inclined surface on the first stop and the third inclined surface on the second stop helps guide the movement direction of the cylindrical bar, making the feeding process smoother and reducing the possibility of jamming or blockage during the movement of the cylindrical bar. The second stop can block the rolling cylindrical bar, and when the second stop retracts, the cylindrical bar on the second inclined surface is fed. At this time, the next cylindrical bar will fall into the groove of the descending push block, and the push is repeated to feed the bar in sequence, avoiding excessive rolling of the cylindrical bar during feeding.

[0019] Secondly, this invention uses a bidirectional screw to control the opening and closing of the limiting bracket, which allows for flexible adjustment of the limiting distance according to cylindrical bars of different diameters. This improves the equipment's adaptability to cylindrical bars of different specifications. The rotatable limiting roller shaft inside the limiting bracket contacts the cylindrical bar, which on the one hand limits the cylindrical bar and prevents it from deviating from the predetermined path during rolling; on the other hand, the rotatable limiting roller shaft reduces the friction between the cylindrical bar and the limiting bracket, making the cylindrical bar roll more smoothly. Furthermore, the detachable mounting platform design allows the equipment to quickly adapt to the processing needs of cylindrical bars of different specifications, improving the equipment's versatility and flexibility.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-4 This utility model provides a technical solution: a continuous feeding vertical band saw, including a support leg 1, on which a feeding mechanism for processing by the vertical band saw is provided, the feeding mechanism including:

[0027] The limiting component includes a processing platform 2 provided on the upper end of the support leg 1. A loading platform 3 is fixed on one side of the processing platform 2 located on the upper end face of the support leg 1. A first inclined surface 301 for loading is provided on the surface of the loading platform 3. A sliding groove 302 is provided at the top of the loading platform 3. A limiting bracket 305 connected by an opening and closing component is provided inside the sliding groove 302.

[0028] The feeding assembly includes a fixed plate 4 fixed to the inner wall of the support leg 1. A fixed rod 401 is fixed to the upper end of the fixed plate 4. A first stop 402 is fixed to the top of the fixed rod 401. A second inclined surface 403 is provided on the upper end of the first stop 402. A support plate 501 connected by a lifting assembly is provided at the center of the upper end of the fixed plate 4. Four sets of vertical rods 502 are fixed to the upper end of the support plate 501. A push block 503 and a second stop 504 are fixed to the top of the vertical rods 502 respectively. A third inclined surface 505 is provided on the upper end of the second stop 504. A discharge inclined block 506 is fixed to the upper end of the processing platform 2 near the second stop 504. An installation platform 604 connected by a detachable assembly is provided on the upper end of the processing platform 2.

[0029] In a preferred embodiment, the opening and closing assembly includes a bidirectional lead screw 303 rotatably connected inside the slide groove 302. A slider bracket 304 is slidably connected to the inner wall of the slide groove 302. A limiting bracket 305 is fixedly connected to one end of the slider bracket 304. Two sets of limiting brackets 305 are configured. The slider bracket 304 is threadedly connected to the bidirectional lead screw 303. Rotatable limiting rollers 306 are evenly distributed on the inner side of the limiting bracket 305. The limiting bracket 305 is slidably connected to the first inclined surface 301. When a cylindrical bar is placed, the bidirectional lead screw 303 is rotated. Since the slider bracket 304 is threadedly connected to the bidirectional lead screw 303 and slides on the inner wall of the slide groove 302, the rotation of the bidirectional lead screw 303 will cause the two sets of slider brackets 304 to move in opposite directions, thereby causing the two sets of limiting brackets 305 to move closer or further apart, adjusting to a suitable distance to match the length of the cylindrical bar.

[0030] Furthermore, when the cylindrical rod is placed on the first inclined surface 301, it will roll towards the lower end of the first inclined surface 301 under the action of gravity. At this time, the rotatable limiting roller 306 inside the limiting bracket 305 comes into contact with the cylindrical rod. On the one hand, it limits the cylindrical rod and prevents it from deviating from the predetermined path during rolling. On the other hand, the rotatable limiting roller 306 can reduce the friction between the cylindrical rod and the limiting bracket 305, making the cylindrical rod roll more smoothly.

[0031] In a preferred embodiment, the lifting assembly includes a first electric push rod 5 that is fixedly fixed inside the fixed plate 4, a support plate 501 that is fixedly connected to the telescopic end of the first electric push rod 5, the support plate 501 and the fixed rod 401 being slidably connected, a push block 503 that is slidably connected to the left side wall of the first stop block 402, and a second stop block 504 that is slidably connected to the right side wall of the first stop block 402.

[0032] Specifically, the first electric push rod 5 is in a retracted state, the support plate 501 is in a lower position, and the push block 503 and the second stop block 504 are also in a lower position. At this time, the cylindrical rods are placed in a suitable position to wait for loading. Multiple cylindrical rods are placed on the first inclined surface 301 of the loading platform 3. Under the action of gravity, the cylindrical rods will roll along the first inclined surface 301 and accumulate at the lower end of the first inclined surface 301. The first electric push rod 5 is activated, and the telescopic end of the first electric push rod 5 extends upward, causing the support plate 501 to slide upward along the fixed rod 401. The rise of the support plate 501 causes the vertical rod 502, the push block 503, and the second stop block 504 to rise together. During the rise of the push block 503, it will push the cylindrical rods, causing the cylindrical rods to move upward. During the rise of the push block 503, it will push the cylindrical rods located to the left of the first stop block 402. The cylindrical bar is pushed upwards. When the push block 503 rises to a certain height, the cylindrical bar passes over the second inclined plane 403. At the same time, the second stop block 504 rises to limit and support the screw rod on the second inclined plane 403. Finally, when the push block 503 and the second stop block 504 descend synchronously, the cylindrical bar will roll back into the groove created by the descent of the push block 503. At this time, the second stop block 504 no longer obstructs the right side of the second inclined plane 403 when it descends. The cylindrical bar rolls through the third inclined plane 505 onto the unloading inclined plane block 506, and then rolls along the unloading inclined plane block 506 to the mounting platform 604 on the processing platform 2. After one loading is completed, the first electric push rod 5 retracts, and the support plate 501, vertical rod 502, push block 503, and second stop block 504 descend back to their initial positions, waiting for the next loading command.

[0033] In a preferred embodiment, the detachable component includes a movable working bracket 6 mounted on the upper surface of the processing platform 2. Limit blocks 601 are fixed to both sides of the lower end of the working bracket 6. A slot 602 is formed on the inner side of each limit block 601. One end of the mounting platform 604 is located inside the slot 602. Bolts 603 are provided on the sidewalls of the limit blocks 601 to connect them to the mounting platform 604. A second electric push rod 605 is fixed through the upper end of the working bracket 6. A pressure block 606 is fixed to the lower end of the second electric push rod 605. A sawing head 201 is mounted on one side of the upper end of the processing platform 2. A saw blade 202 is mounted at the lower end of the sawing head 201. When different specifications need to be changed... When using the mounting table 604 to accommodate the processing needs of cylindrical bars of different sizes, first loosen the bolts 603 on the side wall of the limiting block 601. After loosening the bolts 603, the fastening connection between the mounting table 604 and the limiting block 601 is released. At this time, the mounting table 604 can be removed from the slot 602. According to the processing requirements, select a mounting table 604 of appropriate specifications, align one end with the slot 602 and insert it. Then tighten the bolts 603 to fix the mounting table 604 on the limiting block 601. During the processing, activate the second electric push rod 605. The telescopic end of the second electric push rod 605 extends downward, driving the pressure block 606 fixed at its lower end to descend. During the descent of the pressure block 606, it will press the cylindrical bar placed on the mounting table 604 to prevent the cylindrical bar from moving during the sawing process and ensure sawing accuracy.

[0034] The electric linear actuator used above can be model LAM2-100.

[0035] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0036] When it is necessary to process cylindrical bars, first adjust the limiting components according to the specifications of the cylindrical bars. Rotate the bidirectional lead screw 303. Since the slider bracket 304 is threadedly connected to the bidirectional lead screw 303 and slides on the inner wall of the slide groove 302, the rotation of the bidirectional lead screw 303 will cause the two sets of slider brackets 304 to move in opposite directions, thereby driving the two sets of limiting brackets 305 to move closer or further away from each other. Adjust to a suitable distance to match the length of the cylindrical bars. Then place multiple cylindrical bars on the first inclined surface 301 of the loading platform 3. Under the action of gravity, the cylindrical bars roll towards the lower end of the first inclined surface 301. At this time, the rotatable limiting roller 306 inside the limiting bracket 305 contacts the cylindrical bars, which not only limits them to prevent them from deviating from the path, but also reduces friction to make the rolling smoother.

[0037] Next, the feeding assembly starts working. In the initial state, the first electric push rod 5 is in the retracted state, and the support plate 501, the push block 503, and the second stop block 504 are all in a low position. The cylindrical bars piled up at the lower end of the first inclined surface 301 are waiting to be fed. After the first electric push rod 5 is activated, its telescopic end extends upward, causing the support plate 501 to slide upward along the fixed rod 401, thereby causing the vertical rod 502, the push block 503, and the second stop block 504 to rise together. When the push block 503 rises, it pushes the cylindrical bars located to the left of the first stop block 402 upward. When it rises to a certain height, it... When the cylindrical bar passes the second inclined plane 403, the second stop 504 rises synchronously to limit and support the cylindrical bar on the second inclined plane 403. When the push block 503 and the second stop 504 descend synchronously, the cylindrical bar will roll into the groove created by the descent of the push block 503. At the same time, the descent of the second stop 504 no longer blocks the right side of the second inclined plane 403. The cylindrical bar rolls through the third inclined plane 505 onto the unloading inclined plane block 506, and then rolls along it to the mounting platform 604 on the processing platform 2. After that, the first electric push rod 5 retracts, and all components return to their initial positions to wait for the next loading.

[0038] If the mounting table 604 needs to be replaced to accommodate cylindrical bars of different sizes, first loosen the bolts 603 on the side wall of the limit block 601, remove the mounting table 604 from the slot 602, replace it with a mounting table 604 of the appropriate specification and insert it into the slot 602, tighten the bolts 603 to fix it, and start the second electric push rod 605 during processing. Its telescopic end extends downward to drive the pressure block 606 to descend, pressing the cylindrical bar on the mounting table 604 to prevent it from moving during sawing. Finally, the saw blade 202 at the lower end of the saw head 201 processes the cylindrical bar.
