Description

Technical Field

[0001] This utility model relates to the field of steel bar processing technology, specifically to a steel bar cutting table for construction. Background Technology

[0002] Reinforcing bars are widely used in building structures. When using reinforcing bars in building construction projects, a rebar cutting table is often used to cut the reinforcing bars.

[0003] Existing cutting solutions have some shortcomings. For example, patent document CN216461439U discloses a portable rebar cutting device. This portable rebar cutting device is easy to carry and operate due to its handle; the adjustable component allows for adjustment of the cutting disc position, enabling the cutting of rebars of different lengths; and the cutting component facilitates rebar cutting and disc replacement. However, the distance between the hole for placing the rebar and the cutting mechanism is fixed, limiting the length of rebar that can be cut. Furthermore, this device is only suitable for rebars of a fixed type and is difficult to use for cutting rebars of other diameters, resulting in low practicality.

[0004] It is evident that existing rebar cutting mechanisms still have room for improvement and should be optimized to accommodate rebar cutting of more sizes, increase their flexibility, and facilitate rebar cutting work. Therefore, a more reasonable technical solution is needed to address the technical problems existing in the current technology. Utility Model Content

[0005] To overcome at least one of the aforementioned defects, this utility model proposes a steel bar cutting table for construction, which improves the compatibility of cutting different steel bars by clamping and fixing steel bars of different sizes and models, thereby improving the convenience of using the entire device.

[0006] To achieve the above objectives, the rebar cutting table disclosed in this utility model can adopt the following technical solution:

[0007] A rebar cutting platform includes an outer casing, a cutting mechanism for cutting rebar, and a protective mechanism for preventing debris from splashing. The outer casing has rebar entry holes, and a clamping mechanism for holding the rebar is provided inside the outer casing. The clamping mechanism includes an active clamping plate and a passive clamping plate. The active clamping plate is controlled by a drive assembly to move closer to or away from the passive clamping plate. The passive clamping plate is opposite to the active clamping plate and is used to jointly clamp the rebar. The passive clamping plate is disposed on a retraction assembly and is used to clamp the rebar and move towards the cutting mechanism. The cutting mechanism is disposed inside the outer casing, and the protective mechanism is rotatably disposed on the upper surface of the outer casing and is used to open or close the outer casing.

[0008] The aforementioned rebar cutting table clamps the rebar by placing it in the table and having it clamped by an active clamping plate pushed by an active clamping plate. The rebar is then cut by contact with the cutting mechanism under the continued pushing of the active clamping plate. This structure is applicable to various sizes of steel, offering flexibility, convenience, and good compatibility.

[0009] Furthermore, the drive assembly can adopt various schemes, and its structure is not limited to a single one. Here, we optimize and propose one feasible option: the drive assembly includes a telescopic rod and a connecting rod. The telescopic rod is fixedly connected to the inner wall of the outer casing. The telescopic rod drives the connecting rod to move forward or backward. Both ends of the connecting rod are connected to the active clamping plate and drive the active clamping plate to move synchronously. When adopting the above scheme, the telescopic rod can be an electric telescopic rod, the connecting rod is driven by the telescopic rod, and both ends of the connecting rod are used to connect to the active clamping plate.

[0010] Furthermore, to prevent the connecting rod from being cut by the cutting mechanism, its structure needs to be adjusted to avoid the cutting head. The structure is not limited to a single option; here, optimization is proposed, and one feasible choice is suggested: the portion of the connecting rod opposite the cutting mechanism forms a concave region or a concave bent structure. When adopting the above solution, a concave region can be directly formed on the connecting rod, or the connecting rod can be bent to avoid the cutting mechanism.

[0011] Furthermore, when inserting the reinforcing bar, it can be inserted through a single hole or a double hole; the structure is not uniquely limited. Here, we optimize the process and propose one feasible option: the reinforcing bar entry hole includes a movable slot on the outer wall of the casing. These slots are positioned opposite each other on a pair of side walls of the casing. When inserting the reinforcing bar, it enters through the movable slot on one side wall and extends through the movable slot on the other side wall. Using this scheme ensures that the reinforcing bar is clamped at at least two points, thereby guaranteeing the stability and reliability of the cutting process.

[0012] Furthermore, the retraction component is used to achieve synchronous movement of the clamping component and the reinforcing bar, and to perform cutting after approaching the cutting component. Its structure is not uniquely limited; optimization is proposed here, and one feasible option is suggested: the retraction component includes a retraction rod disposed within the movable groove. The retraction rod is connected to the passive clamping plate and drives the passive clamping plate to retract. A reset component is also provided on the retraction rod, which applies an elastic force to the passive clamping plate to return it to its initial position. In this scheme, the telescopic rod is a sleeve rod. With the cooperation of the reset component, the telescopic rod can be reset after being compressed. The reset component is a reset spring.

[0013] Furthermore, the debris generated during the cutting process needs to be handled: a debris box is slidably connected to the bottom of the outer casing, and the debris box is equipped with a handle. Using this solution, the debris box can be pulled out from the bottom of the outer casing, allowing the collected debris to be dumped.

[0014] Furthermore, the cutting mechanism can adopt various schemes, and its structure is not limited to a single one. Here, we optimize and propose one feasible option: the cutting mechanism includes a motor, the output shaft of which is connected to a coaxially rotating rod, and a cutting head is mounted on the rotating rod. When the above scheme is adopted, when the motor rotates, the output shaft drives the rotating rod and the cutting head to rotate synchronously, and the cutting head can cut the steel bar at the same time.

[0015] Furthermore, to facilitate reinforcement placement before cutting and inspection after cutting, an observation and protective structure can be installed here. The structure is not limited to a single type; one feasible option is proposed here: an opening is formed at the top of the outer casing, with a groove at the opening. The protective mechanism includes a protective cover plate positioned at the groove to cover the opening. With this solution, the opening can be opened or closed via the protective cover plate. When open, the interior of the outer casing can be observed; when closed, internal debris can be prevented from splashing out.

[0016] Furthermore, the protective mechanism is constructed to facilitate sliding in or out. Its structure is not uniquely limited; here, an optimization is proposed, and one feasible option is suggested: the protective mechanism also includes a limiting plate, which is connected to the edge of the protective cover and moves synchronously with the protective cover. When the protective cover slides into the groove and the limiting plate presses against the outer casing, the limiting plate prevents the protective cover from sliding further in. With the above solution, the limiting plate can be integrally formed with the protective cover, connected by fasteners, or engaged by snap-fit ​​connections, etc.

[0017] Furthermore, the connection structure between the protective cover and the limiting plate can adopt various methods, and its structure is not limited to a single one. Here, we optimize and propose one feasible option: the protective cover is provided with a limiting hole, and an elastic limiting head is provided in the limiting hole. Under the elastic force of the elastic element, the elastic limiting head moves towards the limiting plate and gets into the limiting hole on the limiting plate. When adopting the above scheme, the elastic element can be a spring.

[0018] Compared with the prior art, some of the beneficial effects of the technical solution disclosed in this utility model include:

[0019] This invention achieves rebar cutting by clamping and pushing the rebar to the cutting mechanism. The flexible combination of the active clamping plate and the passive clamping plate improves the applicability and can meet the clamping needs of rebars of more sizes, thereby improving the ease of use.

[0028] The following description, in conjunction with the accompanying drawings and specific embodiments, further illustrates this embodiment.

[0029] To address the numerous shortcomings of existing rebar cutting methods, the following embodiments are optimized and overcome the defects in the prior art.

[0030] Example

[0031] like Figures 1-6As shown, this embodiment provides a rebar cutting platform, including an outer box 1, a cutting mechanism 3 for cutting rebar, and a protective mechanism 5 for preventing debris from splashing. The outer box 1 is provided with a rebar entry hole, and a clamping mechanism 2 for clamping the rebar is provided inside the outer box 1. The clamping mechanism 2 includes an active clamping plate 203 and a passive clamping plate 207. The active clamping plate 203 is controlled by a drive component to move closer to or away from the passive clamping plate 207. The passive clamping plate 207 is opposite to the active clamping plate 203 and is used to clamp the rebar together. The passive clamping plate 207 is provided on a retraction component and is used to clamp the rebar and move towards the cutting mechanism 3. The cutting mechanism 3 is provided inside the outer box 1, and the protective mechanism 5 is rotatably provided on the upper surface of the outer box 1 and is used to open or close the outer box 1.

[0032] Preferably, the outer box 1 is provided with a handle 6.

[0033] The rebar cutting table disclosed in this embodiment clamps the rebar by placing it in the table and pushing it from the active clamping plate to the passive clamping plate 207. The rebar is then cut by the continued pushing of the active clamping plate 203, which brings it into contact with the cutting mechanism 3. This structure is applicable to various sizes of steel, offering flexibility, convenience, and good compatibility.

[0034] The drive assembly can adopt various schemes, and its structure is not limited to a single one. This embodiment optimizes and adopts one feasible option: the drive assembly includes a telescopic rod 201 and a connecting rod 202. The telescopic rod 201 is fixedly connected to the inner wall of the outer casing 1. The telescopic rod 201 drives the connecting rod 202 to move forward or backward. The two ends of the connecting rod 202 are connected to the active clamping plate 203 and drive the active clamping plate 203 to move synchronously. When adopting the above scheme, the telescopic rod 201 can be an electric telescopic rod 201. The connecting rod 202 is driven by the telescopic rod 201, and the two ends of the connecting rod 202 are used to connect to the active clamping plate 203.

[0035] To prevent the connecting rod 202 from being cut by the cutting mechanism 3, its structure needs to be adjusted to avoid the cutting head 303. The structure is not uniquely limited; this embodiment optimizes the design and adopts one feasible option: the portion of the connecting rod 202 opposite to the cutting mechanism 3 forms a concave region or a concave bent structure. When using the above solution, a concave region can be directly formed on the connecting rod 202, or the connecting rod 202 can be bent to avoid the cutting mechanism 3.

[0036] When inserting reinforcing bars, they can be inserted through a single hole or a double hole; the structure is not uniquely limited. This embodiment optimizes the process and adopts one feasible option: the reinforcing bar entry hole includes a movable groove 101 set on the wall of the outer casing 1. The movable grooves 101 are arranged opposite each other on a pair of side walls of the outer casing 1. When inserting reinforcing bars, the reinforcing bars enter from the movable groove 101 on one side wall and extend from the movable groove 101 on the other side wall. Using the above scheme ensures that the reinforcing bars are clamped at at least two points, thereby ensuring the stability and reliability of the cutting process.

[0037] The retraction component is used to achieve synchronous movement between the clamping component and the reinforcing bar, and to perform cutting after approaching the cutting component. Its structure is not uniquely limited; this embodiment optimizes and adopts one feasible option: the retraction component includes a retraction rod 205 disposed within the movable groove 101. The retraction rod 205 is connected to the passive clamping plate 207 and drives the passive clamping plate 207 to retract. A reset component 206 is also provided on the retraction rod 205, which applies an elastic force to the passive clamping plate 207 to return it to its initial position. In this scheme, the telescopic rod 201 is a sleeve rod. With the cooperation of the reset component 206, the telescopic rod 201 can be reset after being compressed. The reset component 206 is a reset spring.

[0038] The debris generated during the cutting process needs to be handled: a debris box 4 is slidably connected to the bottom of the outer casing 1, and the debris box 4 is equipped with a handle. Using this solution, the debris box 4 can be pulled out from the bottom of the outer casing 1 to empty the collected debris.

[0039] The cutting mechanism 3 can adopt various schemes, and its structure is not limited to a single one. This embodiment optimizes and adopts one feasible option: the cutting mechanism 3 includes a motor 301, the output shaft of the motor 301 is connected to a coaxially rotating rotating rod 302, and a cutting head 303 is provided on the rotating rod 302. When the above scheme is adopted, when the motor 301 rotates, the output shaft drives the rotating rod 302 and the cutting head 303 to rotate synchronously, and at the same time, the cutting head 303 can cut the steel bar.

[0040] To facilitate reinforcement placement before cutting and inspection after cutting, this embodiment can include an observation and protection structure. The structure is not limited to a single option; this embodiment optimizes and adopts one feasible choice: an opening is formed at the top of the outer casing 1, with a groove 501 at the opening. The protective mechanism 5 includes a protective cover plate 502 disposed at the groove 501 to cover the opening. With this solution, the opening can be opened or closed via the protective cover plate 502. When open, the interior of the outer casing 1 can be observed; when closed, internal debris can be prevented from splashing out.

[0041] The protective mechanism 5 is designed to facilitate sliding in or out. Its structure is not uniquely limited; this embodiment optimizes and adopts one feasible option: the protective mechanism 5 further includes a limiting plate 506, which is connected to the edge of the protective cover 502 and moves synchronously with it. When the protective cover 502 slides into the slide groove 501 and the limiting plate 506 presses against the outer casing 1, the limiting plate 506 prevents the protective cover 502 from sliding further in. With the above solution, the limiting plate 506 can be integrally formed with the protective cover 502, or connected by fasteners, or engaged by snap-fit ​​connections, etc.

[0042] The connection structure between the protective cover 502 and the limiting plate 506 can be implemented in various ways, and its structure is not limited to a single one. This embodiment optimizes the connection and adopts one feasible option: the protective cover 502 is provided with a limiting hole 503, and an elastic limiting head 505 is provided in the limiting hole 503. Under the elastic force of the elastic element 504, the elastic limiting head 505 moves toward the limiting plate 506 and engages with the limiting hole 503 on the limiting plate 506. When adopting the above solution, the elastic element 504 can be a spring.
