[0001] This utility model relates to the field of steel bar sawing workbench technology, and in particular to an automatic steel bar bending machine with a safety guard. Background Technology

[0002] In modern construction, steel bar processing is a crucial step, and automatic steel bar bending machines, as commonly used steel bar processing equipment, primarily function to bend steel bars into desired circular or other shapes. However, traditional automatic steel bar bending machines face some problems in practical use that urgently need to be addressed.

[0003] Traditional automatic rebar bending machines are prone to injuring operators during operation due to the high-speed rotating parts such as the bending pile head, which can cause injury such as clothing or limbs getting caught in the bending pile head. This poses a serious safety hazard. Furthermore, the bending pile head of traditional equipment has a fixed position and shape, which cannot be flexibly adjusted according to different processing requirements, resulting in a limited range of applications. In order to overcome the above-mentioned shortcomings of traditional automatic rebar bending machines, this technical solution proposes an automatic rebar bending machine with a safety guard.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be further described below with reference to the accompanying drawings. The following description presents a preferred embodiment of several possible embodiments of this utility model, intended to provide a basic understanding of the utility model, but not intended to identify the key or decisive elements of the utility model or to limit the scope of protection sought.

[0020] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0021] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures. Also, it should be understood that, for ease of description, the dimensions of the various parts shown in the figures are not drawn to actual scale.

[0022] In the description of this utility model, it should be noted that the circuits, electronic components and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated. The content protected by this utility model does not involve any improvement to the internal structure and method.

[0023] It should be further noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] Please refer to Figure 1 and Figure 2 As shown, an embodiment of this utility model provides an automatic rebar bending machine with a safety guard, including a frame 1, at least two forming wheels 2, a guard, a bending head 6, and two connecting structures. The two forming wheels 2 are rotatably mounted on the upper surface of the frame 1 via a drive device built into the frame 1. The guard is slidably mounted on the frame 1 along the centerline of the two forming wheels 2 via a linear module 3. The position of the guard can be adjusted as needed to adapt to the processing requirements of rebars of different lengths. The guard protects the rebar bending operation area, preventing rebar from flying and injuring people during the bending process, thus improving operational safety.

[0025] Furthermore, the bent pile head 6 is detachably connected to the protective cover via sliders 9 at both ends, which facilitates the disassembly and assembly of the bent pile head 6 for maintenance and replacement. The two connecting structures are respectively located at both ends of the bent pile head 6 and are detachably connected to the sliders 9.

[0026] Please refer to Figure 3 and Figure 4 In this embodiment, the connection structure includes a connecting shaft 10, an inner pusher 11, and multiple retaining beads 13. The inner pusher 11 is slidably disposed inside the connecting shaft 10, and the multiple retaining beads 13 pass through the inner wall of the connecting shaft 10 and are engaged with the slider 9.

[0027] When it is necessary to install or remove the bending pile head 6, the inner push core 11 is pushed or pulled to squeeze or release the locking ball 13, thereby realizing the quick connection or separation between the connecting shaft 10 and the slider 9. At the same time, relative rotation is allowed after connection so that the bending pile head 6 rotates during the bending process of the steel bar, ensuring the bending effect.

[0028] The bending pile head 6 can be separated from the slider 9, so that the bending pile head 6 can be replaced with different diameter specifications to accommodate the bending of steel bars of different diameters.

[0029] Based on the above embodiments, such as Figure 3 As shown, the protective cover has a groove 8, and the slider 9 is inserted into the groove 8. This insertion method allows the slider 9 to slide stably along the groove 8, while ensuring the stability between the protective cover and the bent pile head 6.

[0030] Specifically, a connecting hole is provided in the middle of the slider 9, and the end of the connecting shaft 10 is inserted into the connecting hole so that the connecting shaft 10 and the slider 9 are connected relative to each other. A second groove 14 is provided on the inner wall of the connecting hole of the slider 9, and the retaining bead 13 abuts against the second groove 14, which restricts the axial movement of the connecting shaft 10 and the slider 9 and prevents the bending pile head 6 from undergoing axial displacement during bending. However, relative rotation between the connecting shaft 10 and the slider 9 is allowed at the same time to accommodate the bending action of the reinforcing bar.

[0031] In this embodiment, a first groove 15 is provided on the outer wall of the inner push core 11, and a plurality of bead holes 12 are provided on the inner wall of the connecting shaft 10, with each locking bead 13 correspondingly disposed in a bead hole 12.

[0032] When it is necessary to separate the connecting shaft 10 and the slider 9, push the inner push core 11 to move it until the first groove 15 is aligned with the bead hole 12. At this time, the retaining bead 13 is not subjected to the squeezing force and falls back to the bead hole 12 and the first groove 15, thereby disengaging from the abutment state with the second groove 14 and realizing quick disassembly.

[0033] Based on the above embodiments, such as Figure 4 As shown, a limiting rod 18 is connected to the inner wall of the connecting shaft 10 and is slidably connected to the inner push core 11. An elastic element 19 is connected between the limiting rod 18 and the inner wall of the inner push core 11.

[0034] The longitudinal section of the limiting rod 18 is T-shaped, and its end is slidably connected to the inner wall of the inner push core 11. The elastic element 19 is a spring, one end of which is connected to the end of the limiting rod 18, and the other end is connected to the inner bottom wall of the inner push core 11.

[0035] In this way, the inner pusher 11 can stably push the retaining ball 13 when subjected to axial force, and the elastic element 19 rebounds after the external force is lost, so as to reset the inner pusher 11 and ensure the reliability of the connection between the connecting shaft 10 and the slider 9.

[0036] To facilitate external control of the inner push core 11 by the user, a movable groove 16 communicating with its inner cavity is provided on the outer wall of the connecting shaft 10, and a push rod 17 that is slidably connected to the movable groove 16 is connected to the outer wall of the inner push core 11.

[0037] The push rod 17 can slide within the moving groove 16 by pushing and pulling, thereby driving the inner push core 11 to move within the connecting shaft 10. The operation is simple and facilitates quick connection and disassembly.

[0038] In an alternative embodiment, such as Figure 2 As shown, the protective cover includes a bottom protective frame 4 and a cover plate 5. The cover plate 5 is rotatably connected to the bottom protective frame 4. The bottom protective frame 4 is L-shaped, and the length of the cover plate 5 extends beyond the end of the bottom protective frame 4.

[0039] This design allows the cover plate 5, which extends beyond the end of the bottom protective frame 4, to effectively shield operators from flying steel fragments during the bending process of the steel bars.

[0040] In another optional embodiment, a rotating shaft 41 is rotatably mounted in the inner cavity of the bottom protective frame 4, and an opening 42 is provided on the outer wall of the bottom protective frame 4. One end of the cover plate 5 passes through the opening 42 and is connected to the rotating shaft 41.

[0041] The cover can be opened and closed by rotating the cover plate 5. The operation is simple and convenient, and the cover can be quickly opened or closed when needed to adapt to different operating requirements.

[0042] Based on the above embodiment, at least one support frame 43 is connected to the inner wall of the bottom protective frame 4, and the cover plate 5 abuts against the support frame 43 by a gasket 51, and the cover plate 5 is parallel to the bottom wall of the bottom protective frame 4. The gasket 51 enables the cover plate 5 to remain stable in the closed state and will not be easily opened due to external vibration or impact, thereby improving the protective performance of the cover.

[0043] In addition, a mounting bracket 7 parallel to the bottom wall of the bottom frame 4 is connected to the inner wall of the bottom frame 4, and a groove 8 is provided on the side of the mounting bracket 7 facing the bottom wall of the bottom frame 4.

[0044] Both the mounting bracket 7 and the bottom protective frame 4 are provided with sliding grooves 8 to cooperate with the slider 9, providing stable sliding support for the slider 9 and ensuring that the position of the bent pile head 6 on the protective cover is adjustable and stable.

[0045] In practical use, firstly, according to the specifications and bending requirements of the reinforcing bars, the position of the protective cover is adjusted by the straight module 3 to place the bending pile head 6 in a suitable working position. Then, the forming wheel 2 is rotated by the drive equipment, and the reinforcing bar is inserted into the gap between the forming wheel 2 and the bending pile head 6. The forming wheel 2 drives the reinforcing bar to bend around the bending pile head 6. The protective cover plays a safety protection role throughout the process, preventing accidental injury to people during the high-speed rotation and bending of the reinforcing bar. The ingenious design of the connection structure makes the installation and disassembly of the bending pile head 6 quick and convenient, while ensuring the connection stability between the bending pile head 6 and the protective cover during the bending process, thus improving bending accuracy and work efficiency.

[0046] In this document, the directional terms such as front, back, top, and bottom are defined based on the position of the components in the accompanying drawings and their relative positions to each other, solely for the purpose of clarity and convenience in expressing the technical solution. It should be understood that these are relative concepts and can vary depending on different methods of use and placement; the use of these directional terms should not limit the scope of protection claimed in this application.

[0047] Where there is no conflict, the above embodiments and features described herein can be combined with each other.

[0048] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
