Description

Technical Field

[0001] The utility model mainly relates to the technical field of steel bar bending devices, in particular to an assembled manual device for steel bar bending. Background Art

[0002] During the construction process, most reinforced concrete structures require hooks to be bent at the ends of stirrups, tie bars and other steel bars. In many cases, if the hooks at both ends of the steel bars are bent into place at once during steel bar processing, the installation efficiency of the steel bars will be affected or even the steel bars cannot be installed. Therefore, the steel bars must be bent after the installation is completed. At the same time, under actual working conditions, the installation structure of the steel bars will be different, and the operating space when bending the steel bars will also be limited. Therefore, the steel bar bending device needs to adapt to different installation structures, installation angles and application scenarios, but the existing manual steel bar bending device has a single structure and poor applicability, and cannot adapt to different working conditions.

[0003] Therefore, there is a need for an assembled manual device for bending steel bars that can be disassembled and assembled to be suitable for different working spaces and work needs and is more labor-saving. Utility Model Content

[0007] As a further improvement of the above technical solution:

[0008] The angle α formed between the notch and the shaft of the main rod is 0° to 180°.

[0009] A screw hole is arranged at the bottom of the notch, a through hole is arranged on the rod body of the assembly rod, and a bolt passes through the through hole and is threadedly connected with the screw hole.

[0025] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0026] like Figures 1 to 7As shown, the assembled manual device for steel bar bending of this embodiment includes a main rod 1 and an assembly rod 2; the end of the main rod 1 is formed with a slot 11 for connecting to an external fulcrum, and its rod body is formed with a plurality of notches 12 for connecting to the assembly rod 2; the end of the assembly rod 2 is formed with a protrusion 23 for abutting against the steel bar 01 to be bent, and its rod body is detachably inserted into the notch 12. The external fulcrum is fixed by the slot 11 formed at the end of the main rod 1: when the steel bar 01 to be bent intersects with other steel bars 02, the steel bar 02 can be fixed in the slot 11 as a fulcrum to bend the steel bar 01 to be bent; when the steel bar 01 to be bent does not intersect with other steel bars 02, a screw can be inserted into the slot 11 and fixed without fixing the bending end of the steel bar 01 or ensuring that it does not shift, and the end of the screw can be used as a fulcrum for bending the steel bar. After the external fulcrum is fixed, the protrusion 23 connected to the end of the assembly rod 2 abuts against and applies force to the steel bar 01 to be bent, thereby bending the steel bar 01 to be bent. The assembly rod 2 is detachably connected to the main rod 1 through the notch 12, and by changing the assembly method, the distance between the end of the assembly rod 2 and the end of the main rod 1 is adjusted, which is convenient for bending steel bars of different lengths and angles and suitable for work spaces of different sizes. In addition, by changing the assembly method of the main rod 1 and the assembly rod 2 and the rod length of the main rod 1 and the assembly rod 2, the length of the force arm when bending the steel bar 01 can be changed, thereby adjusting the torque size, making it easier to bend the steel bar.

[0027] In this embodiment, the angle α between the notch 12 and the rod body of the main rod 1 is 0° to 180°. Preferably, three notches 12 are formed on the main rod 1, and the angles α thereof are 45°, 90° and 135° respectively; the angle between the notch 12 and the rod body of the main rod 1 can adjust the positional relationship between the main rod 1 and the assembly rod 2 to determine the relative position of the two ends, so that when the operating space is limited or the bending angle of the steel bar is limited, the position of the two ends can be changed by adjusting the assembly method or position of the device, thereby ensuring that the bending operation is completed under different working conditions.

[0028] In this embodiment, a screw hole 13 is provided at the bottom of the slot 12, and a through hole 24 is provided on the shaft of the assembly rod 2. The bolt 3 passes through the through hole 24 and is threadedly connected with the screw hole 13. Preferably, the shaft of the assembly rod 2 is consistent with the slot 12 in size, and the shaft of the assembly rod 2 is inserted into the slot 12, and the bolt 3 passes through the through hole 24 and is threadedly connected with the screw hole 13 to complete the fixation of the main rod 1 and the assembly rod 2, thereby preventing the main rod 1 and the assembly rod 2 from rotating or moving when a force is applied, which is not conducive to the bending operation.

[0029] In this embodiment, the assembly rod 2 includes a mounting arm 21 and a force-applying arm 22 connected end to end in a broken line shape, and the angle β between the two is 0° to 180°. By setting different angles β, the shape of the assembly rod 2 is changed to achieve different matching connections between the assembly rod 2 and the main rod 1 to adapt to different working scenarios. Preferably, an angle of 90° is most suitable, and its assembly and force-applying properties are the best.

[0030] In this embodiment, a plurality of through holes 24 are arranged at intervals along the central axis of the mounting arm 21. The number of through holes 24 is set to one or more to achieve different installation positions of the main rod 1 and the assembly rod 2, thereby changing the distance between the ends of the assembly rod 2 and the main rod 1, enhancing its applicability to different working environments, and also realizing the adjustment of the torque for bending the steel bars, thereby achieving the effect of saving effort in bending the steel bars.

[0031] In this embodiment, the projection 23 is perpendicular to the force arm 22. The projection 23 is vertically connected to the force arm 22 by bolt 3 connection, welding or other methods, and is used to abut against the steel bar 01 to be bent, apply force to it, and complete the steel bar bending operation. Preferably, the material of the projection 23 can be round steel with greater hardness to better achieve the bending operation. The length of the round steel can preferably be 5 to 10 cm longer than the distance between the end of the assembly rod 2 and the steel bar 01 to be bent, so as to better achieve the bending operation.

[0032] In this embodiment, a plurality of notches 12 are formed along the length direction of the main rod 1, and each notch 12 forms a different angle α with the rod body of the main rod 1. The number of notches 12 is set to be more than one, and each notch 12 forms a different angle α with the rod body of the main rod 1, so different notches can be selected according to different working scenes and different requirements for the bending angle, thereby improving the applicability of the device.

[0033] In this embodiment, the center angle γ of the slot 11 is greater than 180°. The slot 11 is set as an arc-shaped slot with a center angle γ greater than 180°, which is convenient for fixing the external fulcrum, ensuring that the rod fixed in the slot 11 and serving as the fulcrum is not likely to fall out of the slot 11 during operation, and the arc-shaped slot is more convenient for the operation process of rotating around the fulcrum for bending, achieving a more labor-saving and simple effect.

[0034] Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technician familiar with the art can use the above disclosed technical content to make many possible changes and modifications to the technical solution of the present invention without departing from the scope of the technical solution of the present invention, or modify it into an equivalent embodiment of equivalent changes. Therefore, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention should fall within the scope of protection of the technical solution of the present invention.
