[0030] like Figures 1 to 4As shown, an embodiment of the present application provides a bending device for bending an intermediate product 1, the bending device includes a lower mold assembly 2 and an upper mold assembly, the lower mold assembly 2 includes a base 21, a lower mold 22, a positioning member 23 and an elastic member, the lower mold 22 is connected to the base 21, the lower mold 22 is provided with a bending groove 221 for bending the intermediate product 1, the lower mold 22 is also provided with a first mounting hole 222 at the bending groove 221, one end of the positioning member 23 extends into the first mounting hole 222 and is connected to the base 21 through the elastic member, the other end of the positioning member 23 extends into the bending groove 221, the positioning member 23 is provided with a positioning groove 231 for placing the intermediate product 1; the upper mold assembly includes an upper mold 31 and a driving member connected to the upper mold 31, the driving member is used to drive the upper mold 31 to move toward or away from the positioning member 23.

[0031] It should be understood that the intermediate product 1 is formed by cutting the original steel wire, and the intermediate product 1 is a long steel wire. The intermediate product 1 is bent to become the target product 4, which includes a middle section and a bending section, and two bending sections are provided and are respectively located at both ends of the middle section.

[0032] The bending device includes a lower die assembly 2, which includes a base 21, a lower die 22, a positioning member 23 and an elastic member. The base 21 can support the lower die 22, the positioning member 23 and the elastic member. The lower die 22 is connected to the base 21, which can be fixedly connected or detachably connected, and this application does not limit it. The lower die 22 is provided with a bending groove 221, which is arranged at one end of the lower die 22 away from the base 21. The lower die 22 is also provided with a first mounting hole 222, which is located in the bending groove 221 and penetrates the lower die 22 along the height direction of the lower die 22. The positioning member 23 is located in the bending groove 221 and in the first mounting hole 222. The positioning member 23 is provided with a positioning groove 231 at one end facing the upper die assembly. One end of the positioning member 23 is connected to the elastic member and the other end is connected to the base 21. The elastic member can be an elastic material such as a spring or a disc spring, and this application does not limit the material of the elastic member. The elastic member can be compressed and returned to its original position, so that the positioning member 23 can reciprocate along the height direction of the positioning member 23 in a direction toward or away from the base 21 .

[0033] The bending device also includes an upper die assembly, which includes an upper die 31 and a driving member connected to the upper die 31.

[0034] During operation, the intermediate product 1 is placed in the positioning groove 231, and the driving member drives the upper mold 31 to move toward the lower mold assembly 2. The upper mold 31 applies pressure to the positioning member 23. The positioning member 23 is subjected to pressure and moves in a direction away from the upper mold 31, that is, moves downward. The elastic member is compressed, and the intermediate product 1 is bent and deformed in the bending groove 221, thereby forming the target product 4. When the bending is completed, the driving member drives the upper mold 31 to move away from the lower mold assembly 2, the elastic member returns to its position, and the positioning member 23 moves toward the upper mold 31, thereby resetting to facilitate the next bending.

[0035] The present application, through the setting of the bending device, does not require the operator to perform manual bending, does not require the operator's proficiency, increases the bending speed and reduces the bending scrap rate, thereby improving the bending efficiency.

[0036] Reference Figure 1 and Figure 2 In some optional embodiments, the base 21 is provided with a mounting groove, the lower mold 22 is located in the mounting groove, the lower mold 22 is provided with a first engaging portion 223, and the inner wall of the mounting groove is provided with a second engaging portion 213, and the first engaging portion 223 engages with the second engaging portion 213. The base 21 is provided with a mounting groove, the mounting groove is located at one end of the base 21 facing the upper mold assembly, and the lower mold 22 is adapted to the mounting groove and connected to the base 21 through the mounting groove.

[0037] Among them, either the first engaging portion 223 or the second engaging portion 213 is a protrusion, and the other is a groove adapted to the protrusion.

The material of the anti-wear part 225 is wear-resistant hard steel. The setting of the anti-wear part 225 can prevent the intermediate product 1 from causing damage to the lower mold 22. At the same time, when the anti-wear part 225 is damaged, the operator can replace the anti-wear part 225, thereby improving the service life of the lower mold 22 and improving the accuracy of bending the intermediate product 1.
