Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0039] like Figures 1 to 8 As shown, this embodiment provides a rebar bending die, which includes a base 1, a locking component 2, and a bending component 3. The base 1 is provided with a locking groove 11, a first receiving groove 12, and a second receiving groove 13. The locking groove 11 is used to pass through the locking shaft of the rebar bending machine body. The locking component 2 includes a first locking member 21, a first elastic member 22, a second locking member 23, and a second elastic member 24. The first elastic member 22 is disposed in the first receiving groove 12, and the first locking member 21 abuts against the first elastic member 22. The second elastic member 24 is disposed in the second receiving groove 13. 3 abuts against the second elastic member 24. The first locking member 21 and the second locking member 23 are used to clamp the locking shaft. The locking shaft can rotate to push open the first locking member 21 and the second locking member 23 so that the locking shaft can disengage from the locking groove 11. The bending assembly 3 includes a first bending mold block 31 and a second bending mold block 32 spaced apart on the base 1. The first bending mold block 31 and the second bending mold block 32 are corresponding to the base 1. The size of the first bending mold block 31 and the second bending mold block 32 and their position relative to the base 1 are set according to the bending radius required by the reinforcing bar.

[0040] The reinforcing bar is bent and shaped under the positioning action of the first bending die block 31 and the second bending die block 32. The locking shaft of the reinforcing bar bending machine body passes through the locking groove 11 of the base 1. The first locking member 21 and the second locking member 23 clamp the locking shaft extending into the locking groove 11 under the elastic force of the first elastic member 22 and the second elastic member 24, respectively, thereby locking the reinforcing bar bending die and the reinforcing bar bending machine body. The locking shaft can be rotated to open the first locking member 21 and the second locking member 23, and the locking shaft can be disengaged from the locking groove 11, thereby unlocking the reinforcing bar bending die and the reinforcing bar bending machine body. This realizes the automatic locking function of the reinforcing bar bending die, which facilitates the automation of die switching, reduces labor costs, and reduces the time required for die switching.

[0041] To facilitate the installation of the first elastic element 22 and the second elastic element 24, the locking assembly 2 may optionally include a first mounting shaft 25 and a second mounting shaft 26. The base 1 is provided with a first mounting groove 14 and a second mounting groove 15. The first mounting shaft 25 is disposed in the first mounting groove 14. The first elastic element 22 is sandwiched between the first mounting shaft 25 and the first locking element 21. The second mounting shaft 26 is disposed in the second mounting groove 15. The second elastic element 24 is sandwiched between the second mounting shaft 26 and the second locking element 23.

[0042] To prevent the first mounting shaft 25 from disengaging from the first mounting groove 14, the first mounting groove 14 may optionally be provided with a first retaining spring 27, which abuts against the end of the first mounting shaft 25 away from the first elastic member 22. To prevent the second mounting shaft 26 from disengaging from the second mounting groove 15, the second mounting groove 15 may be provided with a second retaining spring 28, which abuts against the end of the second mounting shaft 26 away from the second elastic member 24.

[0043] In some embodiments, both the base 1 of the integrated rebar bending mold and the base 1 of the split rebar bending mold are provided with positioning holes 16 in the same position, so as to replace the integrated or split rebar bending mold. The positioning holes 16 are used to position and cooperate with the positioning protrusions of the rebar bending machine body to ensure the accurate installation position of the rebar bending mold.

[0044] like Figures 1 to 4 As shown, optionally, the first bending mold block 31 and the base 1 are integral structures, and the second bending mold block 32 and the base 1 are integral structures. The first bending mold block 31 and the base 1, as well as the second bending mold block 32 and the base 1, can all be manufactured by integral molding.

[0045] like Figures 5 to 8As shown, optionally, the first bending die block 31 and the base 1 are separate structures, and the second bending die block 32 and the base 1 are also separate structures. By adopting a separate design, the volumes of the first bending die block 31 and the second bending die block 32 can be designed to be relatively large, suitable for bending steel bars requiring a greater degree of bending. Both the first bending die block 31 and the base 1, as well as the second bending die block 32 and the base 1, can be fixedly connected using high-strength bolts. Weight-reducing grooves can be provided at the bottom of the first bending die block 31 and the second bending die block 32.

[0046] Optionally, both the first bending die block 31 and the second bending die block 32 are provided with curved surfaces and inclined surfaces. The inclined surfaces guide and limit the reinforcing bars, while the curved surfaces bend and shape the reinforcing bars. Reinforcing bars with different bending requirements correspond to curved surfaces with different bending radii.

[0047] In some embodiments, both the first elastic element 22 and the second elastic element 24 are springs. Springs are characterized by easy deformation and high elasticity, capable of deforming within a certain range under the action of external force, and returning to their original shape after the external force is removed. Springs have a simple structure, are easy to manufacture, and have low cost.

[0048] Optionally, both the first locking element 21 and the second locking element 23 are steel balls. The durability of steel balls is reflected in their specially treated, smooth, and glossy surface, free of oil and rust, allowing them to maintain good performance in various environments. This makes the steel balls less prone to wear during long-term use, resulting in a long service life. Through cleaning and polishing, the steel balls can be restored to their original state, enabling reuse and reducing resource waste.

[0049] This embodiment also provides a rebar bending machine, including a rebar bending machine body and the aforementioned rebar bending mold. The rebar is bent and shaped under the positioning action of the first bending mold block 31 and the second bending mold block 32. The top of the locking shaft of the rebar bending machine body is provided with a plurality of circumferentially distributed first protrusions, and a first groove is formed between adjacent first protrusions. A second protrusion is provided in the locking groove 11, and a second groove is formed between adjacent second protrusions. When the locking shaft passes through the locking groove 11 of the base 1, the first protrusion aligns with the second groove and penetrates the second groove. When the first protrusion is fully inserted into the locking groove 11, it will push open the first locking member 21 and the second locking member 23 and compress the first elastic member 22 and the second elastic member 24. At this time, the locking shaft rotates forward under the action of the driving force, so that the first protrusion and the second protrusion are aligned and locked, so that the locking shaft is axially limited and locked, preventing the locking shaft from axially disengaging from the locking groove 11. At the same time, the first locking member 21 and the second locking member 23 are respectively located in the first elastic member 22 and the second elastic member 24. The elastic force of the 4 is locked in the first groove between the adjacent first protrusions on the top of the locking shaft. The first locking member 21 and the second locking member 23 clamp the locking shaft extending into the locking groove 11 under the elastic force of the first elastic member 22 and the second elastic member 24, respectively, so that the locking shaft is circumferentially limited and locked. When there is no external force, the locking shaft cannot rotate freely, thereby locking the rebar bending mold and the rebar bending machine body. The locking shaft can rotate in the opposite direction under the action of the driving force, so that the first protrusion on the top of the locking shaft pushes open the first locking member 21 and the second locking member 23, overcoming the elastic force of the first elastic member 22 and the second elastic member 24. Then the first protrusion of the locking shaft is misaligned with the second protrusion of the locking groove 11, without interference, so that the first protrusion can pass through the second groove, and the locking shaft can disengage from the locking groove 11, thereby unlocking the rebar bending mold and the rebar bending machine body. This realizes the automatic locking function of the rebar bending mold, which is easy to automate mold switching, reduces labor costs, and reduces mold switching time.

Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention.
