Description

Technical Field

[0001] This utility model relates to the field of metal wire processing, and more specifically, to a steel bar cutting device for steel bar processing. Background Technology

[0002] In steel bar processing, it is often necessary to cut a section of steel bar into several sections of equal length. Cutting machines are used for the division and cutting of materials in various industries. They directly cut products and are cutting equipment used in many industries.

[0003] Chinese patent CN218283575U discloses a steel bar cutting device for steel bar processing. By setting fixed support blocks and floating support blocks on both sides of the upper and lower shearing blades to support the steel bar cutting process, the two ends of the steel bar at the cutting position can be fixed and pressed tightly during the cutting process, which can effectively prevent the steel bar from loosening. This ensures both the processing accuracy and the safety of the cutting process.

[0004] While the aforementioned patent can effectively prevent the steel bars from loosening during the shearing process, the steel bars are cut in large batches, and the length of the steel bars needs to be measured each time, which is a cumbersome and labor-intensive process. Utility Model Content

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a rebar cutting device for rebar processing. When the rebar moving and pressing block moves to the bottom of the semi-circular groove, the top of the protruding block is flush with the upper surface of the cover plate, making it easy for workers to know that the rebar has reached the bottom of the semi-circular groove. At this time, the length of the rebar is the length to be cut. Each semi-circular groove is fixedly connected to a measuring mechanism, making it easy for workers to observe the length of each rebar left, eliminating the need for workers to check each one, making the device more convenient to use. It also eliminates the need for workers to adjust the length of the rebar, making it more convenient to use. Color is applied to the top of each protruding block, making it easier to observe the extension of the protruding block.

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0007] A steel bar cutting device for steel bar processing includes a machine body, and an adjustment mechanism is provided inside the machine body;

[0008] The adjustment mechanism includes a mounting plate fixedly connected to the body, a support block fixedly connected to the top left side of the mounting plate, a lower cover plate slidably connected to the top of the mounting plate, and an upper cover plate rotatably connected to the top of the lower cover plate. Both the upper cover plate and the lower cover plate have multiple equally spaced semicircular grooves inside, and a measuring mechanism is provided inside the semicircular groove of the upper cover plate.

[0009] The measuring mechanism includes an extrusion block that is slidably connected to the upper cover plate, and an extension block that is slidably connected inside the upper cover plate at the position corresponding to the movement trajectory of the extrusion block.

[0010] Furthermore, a second spring is welded between the extrusion block and the bottom of the semi-circular groove, the cross-sectional shape of the protruding block is a right trapezoid, and a third spring is welded to the right side of the protruding block. The second spring and the third spring are in a naturally extended state when the extrusion block is not moved.

[0011] Furthermore, the front and rear sides of the lower cover plate are movably connected to limit blocks, and the interior of the mounting plate is provided with an L-shaped groove to accommodate the movement of the limit blocks, corresponding to the movement trajectory of the limit blocks.

[0012] Furthermore, the L-shaped groove has multiple first circular holes that are evenly distributed inside, the top of the machine body is provided with a cutting mechanism, and the top of the limiting block extends upward to form an extension rod.

[0013] Furthermore, a through groove is provided inside the lower cover plate corresponding to the position of the extension rod, and the bottom of the lower cover plate extends downward to form an extension block, which is inserted into the groove on the top side of the L-shaped groove.

[0014] Furthermore, the upper cover plate has inclined grooves on both the front and rear sides, and a first spring welded to the extension rod is provided inside the groove. The first spring is in a naturally extended state when the lower cover plate is not moved, and the elastic coefficient of the second spring is less than that of the first spring.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This solution inserts a reinforcing bar into the semi-circular groove, keeping the other end of the bar radially fixed. This allows the bar to move only towards the support block. Once fixed, cutting the bar becomes easier. The protruding block is compressed and moves to the top of the upper cover plate, facilitating its extension from inside the cover plate. When the bar moves and compresses the compression block to the bottom of the semi-circular groove, the top of the protruding block is flush with the upper surface of the cover plate, allowing workers to easily see when the bar has reached the bottom. At this point, the bar's length is the required cutting length. Each semi-circular groove is fixedly connected to a measuring mechanism, allowing workers to easily observe the length of each bar, eliminating the need for individual checks and making the device more convenient to use. Furthermore, no manual adjustment of the bar length is required. Color is applied to the top of each protruding block, further enhancing the ease of observation.

[0017] 2. This solution uses a movable limiting block to move the lower and upper cover plates. The limiting block can be moved according to the required length of the rebar to be cut, allowing for the cutting of rebars of different sizes and broadening the device's applicability. When the cutting mechanism cuts the rebar, the right-side rebar moves towards the upper cover plate due to the pressure from the cutting tool. After cutting is complete and the cutting mechanism has moved away, the cutting tool no longer pressures the rebar, leaving both ends unrestricted. The rebar then falls downwards. The mounting plate has a U-shaped cross-section, facilitating the downward fall of the rebar. A collection device is placed at the point where the rebar falls, making collection more convenient.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1 to 6A rebar cutting device for rebar processing includes a body 1. An adjustment mechanism 2 is installed inside the body 1. The adjustment mechanism 2 includes a mounting plate 21 fixedly connected to the body 1. A support block 3 is fixedly connected to the top left side of the mounting plate 21. Rebar is placed on the surface of the support block 3, and the rebar is moved by a feeding device (which is existing technology and will not be described here). The support block 3 has multiple semi-circular grooves on its surface to facilitate placing one end of the rebar on the surface of the support block 3. A lower cover plate 23 is slidably connected to the top of the mounting plate 21, and an upper cover plate 22 is rotatably connected to the top of the lower cover plate 23. By rotating the upper cover plate 22, it rotates around the lower cover plate 23, facilitating placing the other end of the rebar on the surface of the lower cover plate 23. The upper cover plate 22 and the lower cover plate 23 are connected in a slidable manner. The interior of each cover plate 23 has multiple equally spaced semicircular grooves 233. By inserting the reinforcing bar into the semicircular groove 233, the other end of the reinforcing bar is kept radially fixed, allowing the reinforcing bar to move only towards the support block 3. After the reinforcing bar is fixed, cutting the reinforcing bar is more convenient. The upper cover plate 22 and the lower cover plate 23 are connected by a rotating shaft and a torsion spring to form a reset mechanism (this is prior art and will not be described here). Then, the upper cover plate 22 is released, allowing it to return to its original position under the action of the rotating shaft and the torsion spring. A measuring mechanism 5 is provided inside the semicircular groove 233 of the upper cover plate 22. The measuring mechanism 5 includes a pressing block 52 that is slidably connected to the upper cover plate 22. The semicircular grooves 233 in the upper cover plate 22 and the lower cover plate 23 form a circle, facilitating the entry of the reinforcing bar into the upper cover plate. Between the upper cover plate 22 and the lower cover plate 23, when the reinforcing bar extends into the semicircular groove 233, it presses against the pressing block 52. After being pressed, the pressing block 52 moves into the upper cover plate 22, making its movement more convenient. Inside the upper cover plate 22, a protruding block 53 is slidably connected to the position corresponding to the movement trajectory of the pressing block 52. During the movement of the pressing block 52, it presses against the protruding block 53, causing it to move to the top of the upper cover plate 22, facilitating its extension from inside the upper cover plate 22. When the reinforcing bar moves and presses the pressing block 52 to the bottom of the semicircular groove 233, the top of the protruding block 53 is flush with the upper surface of the upper cover plate 22, allowing workers to know that the reinforcing bar has reached the bottom of the semicircular groove 233. At this point, the length of the reinforcing bar is the length to be cut. Each semicircular groove 233 is fixedly connected to a measuring mechanism 5, facilitating the observation of the length of each rebar without requiring manual inspection, thus making the device more convenient to use. The top of each protruding block 53 is coated with color, making it easier to observe its extension. A second spring 51 is welded between the pressing block 52 and the bottom of the semicircular groove 233. When the pressing block 52 moves, it compresses the second spring 51, causing it to change from a naturally extended state to a taut state. This allows the pressing block 52 to return to its original position under the action of the second spring 51, enabling the device to be reused. The cross-sectional shape of the protruding block 53 is a right-angled trapezoid.Furthermore, the inclined surface of the protruding block 53 is close to the pressing block 52. When the pressing block 52 presses against the protruding block 53, the pressing block 52 presses against the inclined surface of the protruding block 53, facilitating the movement of the protruding block 53 under pressure. The movement of the protruding block 53 is more convenient. A third spring 54 is welded to the right side of the protruding block 53. During the upward movement of the protruding block 53, the third spring 54 is compressed by the protruding block 53 and becomes taut, facilitating the return of the protruding block 53 to its original position under the action of the third spring 54. This allows the device to be reused. The second spring 51 and the third spring 54 are in a naturally extended state when the pressing block 52 is not moving.

[0028] like Figures 1 to 6As shown, limit blocks 24 are movably connected to both the front and rear sides of the lower cover plate 23. By moving the limit blocks 24, the lower cover plate 23 and the upper cover plate 22 can be moved together. At this time, the limit blocks 24 can be moved according to the required length of the steel bars, and steel bars of different sizes can be cut, making the device more widely applicable. The interior of the mounting plate 21 is provided with an L-shaped groove 211 to accommodate the movement of the limit blocks 24, corresponding to the movement trajectory of the limit blocks 24. By moving the limit blocks 24 inside the L-shaped groove 211, the movement of the limit blocks 24 is more convenient and stable. The interior of the L-shaped groove 211 is provided with multiple first circular holes 212 that are evenly distributed. When the limit blocks 24 are moved to the appropriate position, they are fixed by bolts passing through the limit blocks 24 and the corresponding first circular holes 212. The device can fix the limiting blocks 24 at different positions, making the application range of the device wider. The cutting mechanism 4 is set at the top of the inside of the machine body 1. The cutting mechanism 4 cuts the steel bar. When the cutting tool of the cutting mechanism 4 cuts the steel bar, the steel bar on the right side moves towards the upper cover plate 22 due to the pressure of the cutting tool itself. At this time, the steel bar presses against the upper cover plate 22 and the lower cover plate 23, causing the lower cover plate 23 to move at the top of the limiting block 24. The top of the limiting block 24 extends upward to form an extension rod 241. The lower cover plate 23 has a through groove 231 at the position corresponding to the extension rod 241. At this time, the lower cover plate 23 moves along with the through groove 231. The extension rod 241 restricts the lower cover plate 23, so that the lower cover plate 23 can only move left and right. The bottom of the lower cover plate 23 An extension block 234 extends downwards, fitting into the top side of the L-shaped groove 211. The L-shaped groove 211 restricts the extension block 234, improving the movement of the lower cover plate 23 with the limiting block 24. When the lower cover plate 23 moves with the upper cover plate 22, inclined grooves 221 are provided on both the front and rear sides of the upper cover plate 22. During the movement of the upper cover plate 22, the extension rod 241 presses against the inclined groove 221. The inclined groove 221 has a triangular cross-section, facilitating the pressing of the extension rod 241. At this time, the inclined groove 221 moves due to the pressure, allowing the upper cover plate 22 to rotate around the lower cover plate 23. At this point, the upper cover plate 22 separates from the lower cover plate 23, allowing the end of the reinforcing bar inserted into the upper cover plate 22 and lower cover plate 23 to move. After the rebar is cut and the cutting mechanism 4 has left, when the blade no longer compresses the rebar, both ends of the rebar are unrestricted and fall downwards. The mounting plate 21 has a U-shaped cross-section, facilitating the downward fall of the rebar. A collection device is placed at the point where the rebar falls, making collection more convenient. Inside the through groove 231, a first spring 232 is welded to the extension rod 241. During the movement of the lower cover plate 23, the lower cover plate 23 and the extension rod 241 compress the first spring 232, causing it to change from a naturally extended state to a taut state. This allows the lower cover plate 23 to bring the upper cover plate 22 back to its original position, making the device reusable. When the lower cover plate 23 is not moving, the first spring 232 is in a naturally extended state.The elastic coefficient of the second spring 51 is less than that of the first spring 232. When the reinforcing bar presses against the pressing block 52, the elastic coefficient of the first spring 232 is greater than that of the second spring 51, preventing the lower cover plate 23 from moving when the reinforcing bar presses against the pressing block 52. The lower cover plate 23 will only move when the cutting mechanism 4 cuts the reinforcing bar, causing the reinforcing bar to press against the lower cover plate 23.

[0029] The above are merely preferred embodiments of this utility model; however, the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and its improved concept, should be included within the scope of protection of this utility model.
