Those skilled in the art can easily understand the other advantages and effects of the present utility model from the content disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Refer to the attached Figure 1 - attached Figure 4 , a hardware bending device capable of reducing wear provided by the present utility model, includes a bending machine frame 1, the bending machine frame 1 includes a machine frame 11, a hydraulic cylinder 12 is fixedly arranged at the top of the machine frame 11, an upper die bending blade 13 is fixedly arranged at the output end of the hydraulic cylinder 12, a bending lower die assembly 2 is arranged at the top of the machine frame 11, the bending lower die assembly 2 includes a lower die frame 21, the lower die frame 21 is fixedly arranged at the bottom of the machine frame 11, two telescopic rods 22 are arranged at the top of the lower die frame 21, springs 23 are sleeved outside the two telescopic rods 22, a connecting plate 24 is fixedly arranged at the top of the two telescopic rods 22, a connecting rod 25 is fixedly inserted inside the connecting plate 24, two lower die bending plates 26 are sleeved outside the connecting rod 25, limiting grooves 27 are opened on both sides of the two lower die bending plates 26, and connecting units 28 are sleeved outside the two lower die bending plates 26;

[0025] In this implementation, to prevent friction between the hardware part and the lower die bending plate 26 when bending the hardware part, the hardware part is placed on two lower die bending plates 26, and the hardware part is positioned at the bottom of the upper die bending blade 13. The hydraulic cylinder 12 is activated to move the output end downward, causing the upper die bending blade 13 to contact the hardware part and press down on the hardware part on top of the lower die bending plate 26. When the lower die bending plate 26 moves downward, an included angle is formed between the two lower die bending plates 26, and the hardware part is bent by the formed included angle. When the hardware part is bent, it does not slide relative to the lower die bending plate 26, thus preventing friction from occurring between the hardware part and the lower die bending plate 26 during bending, reducing wear, and increasing the service life.

[0026] Among them, to prevent interference when the lower die bending plate 26 is bent, the following technical solution is adopted in this device: The connection unit 28 includes a connection sleeve 281. The connection sleeve 281 is sleeved outside the lower die bending plate 26 and is slidably connected to the lower die bending plate 26. Two limit blocks 282 are fixedly arranged inside the connection sleeve 281, and a connection block 283 is fixedly arranged at the bottom of the connection sleeve 281. A rotating shaft 284 is fixedly inserted into the connection block 283. The limit blocks 282 extend into the limit groove 27 and are slidably connected to the limit groove 27. The rotating shaft 284 penetrates through both side walls of the lower die holder 21 and is connected to both side walls of the lower die holder 21 through bearings. When the connection area of the two lower die bending plates 26 moves downward, the lower die bending plate 26 can rotate through the cooperation of the rotating shaft 284 in the connection unit 28 and the lower die holder 21. When the lower die bending plate 26 rotates, to keep the connecting rod 25 still in the central position, through the cooperation of the limit block 282 and the limit groove 27, the lower die bending plate 26 and the connection unit 28 can slide relative to each other to compensate for the movement difference during the rotation of the lower die bending plate 26.

[0027] Among them, in order to achieve the purpose of facilitating the reset of the lower die bending plate 26, the present device adopts the following technical solutions: the output end of the hydraulic cylinder 12 penetrates through the top of the frame 11 and is slidably connected to the top of the frame 11. The two ends of the spring 23 are respectively fixedly connected to the two ends of the telescopic rod 22. The bottom of the telescopic rod 22 is fixedly connected to the bottom of the frame 11. The connecting rod 25 penetrates through the two lower die bending plates 26 and is slidably connected to the two lower die bending plates 26. The two lower die bending plates 26 intersect and are slidably connected. Place the hardware on the two lower die bending plates 26 and make the hardware located at the bottom of the upper die bending blade 13. Start the hydraulic cylinder 12 to make the output end move downward, so that the upper die bending blade 13 contacts the hardware and presses down the hardware on the top of the lower die bending plate 26. When the lower die bending plate 26 moves downward, an included angle will be formed between the two lower die bending plates 26. The movement of the lower die bending plate 26 drives the connecting rod 25 to move downward. When the connecting rod 25 moves downward, it drives the connecting plate 24 to move downward. The movement of the connecting plate 24 causes the spring 23 and the telescopic rod 22 to contract. Through the elastic force of the telescopic rod 22, it is convenient for the subsequent reset of the lower die bending plate 26.

[0028] The use process of the present utility model is as follows: When using the present utility model, the hydraulic cylinder 12 is connected to a hydraulic mechanism. When it is necessary to bend the hardware, place the hardware on the two lower die bending plates 26 and make the hardware located at the bottom of the upper die bending blade 13. Start the hydraulic cylinder 12 to make the output end move downward, so that the upper die bending blade 13 contacts the hardware and presses down the hardware on the top of the lower die bending plate 26. When the lower die bending plate 26 moves downward, an included angle will be formed between the two lower die bending plates 26. The hardware is bent through the formed included angle. When the hardware is bent, it will not slide on the lower die bending plate 26, thereby preventing friction when the hardware and the lower die bending plate 26 are bent, further reducing the occurrence of wear and improving the service life. At the same time, when the connection area of the two lower die bending plates 26 moves downward, through the cooperation of the rotating shaft 284 in the connection unit 28 and the lower die holder 21, the lower die bending plate 26 can rotate. When the lower die bending plate 26 rotates, in order to make the connecting rod 25 still in the central position, through the cooperation of the limiting block 282 and the limiting groove 27, the lower die bending plate 26 and the connection unit 28 can relatively slide to compensate for the movement difference when the lower die bending plate 26 rotates. At the same time, when the connecting rod 25 moves downward, it drives the connecting plate 24 to move downward. The movement of the connecting plate 24 causes the spring 23 and the telescopic rod 22 to contract. Through the elastic force of the telescopic rod 22, it is convenient for the subsequent reset of the lower die bending plate 26.

[0029] The above is only a preferred embodiment of the present utility model. Any person skilled in the art may modify the present utility model by using the technical solutions described above or modify it into an equivalent technical solution. Therefore, any simple modification or equivalent replacement made according to the technical solutions of the present utility model falls within the scope of protection required by the present utility model.
