Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of steel bar cutting equipment. Specifically, it particularly relates to a steel bar cutting machine with an opening adjusting structure. Background Art
[0002] Steel bars refer to steel materials used in reinforced concrete and prestressed reinforced concrete. Their cross-section is circular, and sometimes square with rounded corners. It includes plain round bars, ribbed bars, and twisted bars. Steel bars are widely used in various building structures, especially large-scale, heavy-duty, light-thin-walled, and high-rise building structures. Due to different usage scenarios, steel bars need to be cut into different lengths to be put into normal use, and a steel bar cutting machine is required during cutting.
[0003] Currently, the rechargeable steel bar cutting machines on the market can cut steel bars of different diameters. A guide block is set at the opening. During operation, the steel bar needs to slowly approach the saw blade along the guide block. Due to its own cutting requirements, a relatively large opening is needed. When cutting a steel bar with a smaller diameter, since it is a hand-held operation, it will shake. When the steel bar advances along the guide block, it is not easy to maintain a posture perpendicular to the saw blade, which will affect the flatness of the cutting surface, as well as the cutting power consumption and efficiency.
[0004] Regarding the problems in the related technology, no effective solution has been proposed yet. Content of the Utility Model

[0030] Please refer to Figures 1-6 As shown, the present utility model is a steel bar cutting machine with an opening adjustment structure, including a grip 1. It is characterized in that a connecting seat 2 is fixedly connected to the outer surface of the grip 1, a U-shaped groove 3 is opened on the outer surface of the connecting seat 2, a cutting blade 4 is rotatably connected inside the connecting seat 2, a locking component 5 and an adjusting component 6 are slidably connected inside the connecting seat 2, a reset component 7 is arranged inside the locking component 5, the locking component 5 is used to fix the adjusting component 6, the adjusting component 6 is used to change the size of the opening of the U-shaped groove 3, and the reset component 7 is used to push the locking component 5 to reset.
[0031] Push the locking component 5 to make the locking component 5 slide downward on the connecting seat 2. The locking component 5 compresses the reset component 7. At this time, the locking component 5 releases the limit fixation on the adjusting component 6. Push the locking component 5 to drive the adjusting component 6 to move. The adjusting component 6 moves in the U-shaped groove 3, so that the adjusting component 6 presses the steel bar in the U-shaped groove 3. Then push the steel bar to move along the U-shaped groove 3 in the direction close to the cutting blade 4, and the steel bar can be cut off.
[0032] Through the connection of the locking component 5 and the adjusting component 6, when the locking component 5 moves downward, the locking component 5 is separated from the connecting seat 2. At this time, the limit fixation between the connecting seat 2 and the adjusting component 6 can be released. By pushing the locking component 5, the adjusting component 6 can be driven to move. The adjusting component 6 moves within the U-shaped groove 3, and the opening size of the U-shaped groove 3 can be changed. At this time, steel bars with a smaller diameter can be fixed to avoid large fluctuations during cutting, which may cause uneven cut surfaces.
[0033] In one embodiment, for the above-mentioned locking component 5, the locking component 5 includes a cylinder 501. A waist-shaped groove 502 and a limit groove 503 are formed on the outer surface of the connecting seat 2. The cylinder 501 is slidably connected inside the waist-shaped groove 502. A sliding rod 504 is slidably connected inside the cylinder 501. A limit block 505 is fixedly connected to the lower end of the sliding rod 504. The limit block 505 is inserted into the limit groove 503.
[0034] Press the sliding rod 504. The sliding rod 504 slides inside the cylinder 501, and the sliding rod 504 pushes the limit block 505 downward, causing the limit block 505 to be separated from the limit groove 503. At this time, the sliding rod 504 and the cylinder 501 can drive the adjusting component 6 to move along the waist-shaped groove 502.
[0035] In one embodiment, for the above-mentioned adjusting component 6, the adjusting component 6 includes a sliding plate 601. A chute 602 is formed inside the connecting seat 2. The sliding plate 601 is slidably connected inside the chute 602. A clamping plate 603 is fixedly connected to the outer surface of the sliding plate 601. The sliding plate 601 is fixedly connected to the cylinder 501. The sliding rod 504 passes through the sliding plate 601 and is slidably connected to it.
[0036] The sliding rod 504 and the cylinder 501 drive the sliding plate 601 to move. The sliding plate 601 slides along the chute 602. At the same time, the sliding plate 601 pushes the clamping plate 603 to move inside the U-shaped groove 3, so that the clamping plate 603 can fix the steel bar with a smaller size inside the U-shaped groove 3, avoiding shaking when cutting the steel bar with a smaller size.
[0037] In one embodiment, for the above-mentioned reset component 7, the reset component 7 includes a limit plate 701. The limit plate 701 is fixedly connected to the sliding rod 504. The limit plate 701 is slidably connected inside the cylinder 501. A spring 702 is fixedly connected to the bottom of the limit plate 701. The spring 702 is sleeved on the outer surface of the sliding plate 601 and is fixedly connected to the sliding plate 601.
[0038] The sliding rod 504 drives the limit plate 701 to move downward. The limit plate 701 compresses the spring 702. The limit plate 701 can only slide inside the cylinder 501, so that the moving distances of the limit plate 701 and the sliding rod 504 are restricted. When the sliding rod 504 is released, the spring 702 pushes the limit plate 701 to reset. The limit plate 701 drives the sliding rod 504 to reset. The limit block 505 on the sliding rod 504 returns to the limit groove 503, and the limit block 505 can limit and fix the sliding plate 601.
[0039] In one embodiment, for the above-mentioned cylinder 501, an anti-misoperation component 8 is provided at the top of the cylinder 501.
[0040] In one embodiment, for the above-mentioned anti-misoperation component 8, the anti-misoperation component 8 includes a fixed seat 801. A rotating rod 802 is rotatably connected to the outer surface of the fixed seat 801. An end of the sliding rod 504 is fixedly connected to a pressing plate 803. A square groove 804 is formed on the outer surface of the pressing plate 803. A first magnet 805 is fixedly connected inside the square groove 804. A second magnet 806 is fixedly connected to the outer surface of the rotating rod 802. The rotating rod 802 is fixed inside the square groove 804 through the second magnet 806 and the first magnet 805.
[0041] Push the rotating rod 802 to rotate around the fixed seat 801. The second magnet 806 on the rotating rod 802 is separated from the first magnet 805. Then the rotating rod 802 is screwed out from the square groove 804 on the pressing plate 803. At this time, the pressing plate 803 and the sliding rod 504 can be pushed to move downward. When the pressing plate 803 and the sliding rod 504 do not need to move, screw the rotating rod 802 back into the square groove 804 on the pressing plate 803. The second magnet 806 on the rotating rod 802 adsorbs to the first magnet 805 inside the square groove 804, so that the rotating rod 802 is fixed inside the square groove 804. At this time, when the pressing plate 803 moves downward, it will be blocked by the rotating rod 802, avoiding the situation of accidentally touching the pressing plate 803.
[0042] In one embodiment, for the above-mentioned pressing plate 803, an anti-slip groove 9 is provided at the top of the pressing plate 803.
[0043] The provision of the anti-slip groove 9 makes the surface of the pressing plate 803 uneven, thereby increasing the friction between the pressing plate 803 and the fingers of the staff, facilitating the staff to push the pressing plate 803 and the sliding plate 601 to move.
[0044] In one embodiment, for the above-mentioned locking component 5, the locking component 5 may further include a second sliding rod, which is slidably connected to the connecting seat 2. The upper end of the second sliding rod is fixedly connected to a second pressing plate. A second spring is fixedly connected between the second pressing plate and the connecting seat 2. The second spring is sleeved on the outer surface of the second sliding rod. The lower end of the second sliding rod is fixedly connected to a second limiting block. A plurality of second limiting grooves matching the second limiting block are formed at the bottom of the sliding plate 601. A second waist-shaped groove is formed at the bottom of the sliding plate 601. The second sliding rod is slidably connected to the sliding plate 601 through the second waist-shaped groove.
[0045] Press the second pressing plate to drive the second sliding rod to slide downward. The second pressing plate compresses the second spring. The second limiting block at the lower end of the second sliding rod separates from the second limiting groove on the sliding plate 601, releasing the limit fixation of the sliding plate 601. The sliding plate 601 can be pushed to move. The second sliding rod is located in the second waist-shaped groove on the sliding plate 601, which can avoid the situation that the second sliding rod blocks the movement of the sliding plate 601. The sliding plate 601 and the clamping plate 603 slide in the U-shaped groove 3, so that the clamping plate 603 can approach the steel bar in the U-shaped groove 3.
[0046] In summary, by means of the above technical solution of the present utility model, the rotating rod 802 is pushed to rotate around the fixed seat 801. The rotating rod 802 rotates out from the square groove 804 on the pressing plate 803, releasing the limit fixation of the pressing plate 803. The pressing plate 803 and the sliding rod 504 are pushed to move downward. The sliding rod 504 drives the limiting plate 701 to move and compresses the spring 702. The sliding rod 504 pushes the limiting block 505 to separate from the limiting groove 503. At this time, the sliding rod 504 can be pushed to drive the sliding plate 601 to move along the sliding groove 602. The cylinder 501 on the sliding rod 504 slides in the waist-shaped groove 502. The sliding plate 601 drives the clamping plate 603 to move in the U-shaped groove 3. Place the steel bar to be cut in the U-shaped groove 3. The clamping plate 603 can limit the distance of the steel bar from swaying left and right in the U-shaped groove 3, avoiding the situation that the cutting blade 4 cuts the steel bar with large swaying during the cutting process, resulting in uneven cut. The staff can complete the operations of pushing the pressing plate 803 to descend and the sliding plate 601 to move with one hand, and it is more convenient to adjust the positions of the sliding plate 601 and the clamping plate 603.
[0047] Through the above technical solutions: 1. Through the connection between the locking component 5 and the adjusting component 6, when the locking component 5 moves downward, the locking component 5 is separated from the connecting seat 2. At this time, the limit fixation between the connecting seat 2 and the adjusting component 6 can be released, and the locking component 5 is pushed to drive the adjusting component 6 to move. The adjusting component 6 moves within the U-shaped groove 3, and the opening size of the U-shaped groove 3 can be changed. At this time, steel bars with a smaller diameter can be fixed to avoid large fluctuations during cutting, which may lead to uneven cut surfaces. 2. Through the connection between the sliding rod 504 and the sliding plate 601, when the size of the steel bar to be cut is small, the sliding rod 504 is pressed. The sliding rod 504 drives the limiting block 505 to move, and the limiting block 505 is separated from the limiting groove 503, releasing the limit fixation of the sliding rod 504. At this time, pushing the sliding rod 504 can drive the sliding plate 601 to move. The sliding plate 601 drives the clamping plate 603 to slide within the U-shaped groove 3, so that the clamping plate 603 approaches the steel bar within the U-shaped groove 3, avoiding large fluctuations of the steel bar during cutting, which may lead to uneven cut surfaces.
