[0031] In the embodiment: through the positioning mechanism 3 and the upper die structure 4, first, the metal support plate is placed on the top of the support plate 34, and then the distance structure 39 at the rear side of the frame 1 is moved according to the preset parameters to accurately limit the position of the tail end of the plate, ensure the accurate control of the bending distance, then the motor 32 is started, the output shaft drives the bidirectional screw rod 31 to rotate, because the screw threads on both sides of the bidirectional screw rod 31 are opposite, the moving frame 33 connected by the surface screw threads will move towards or in the opposite direction, the moving frame 33 drives the support seat 35 to slide outside the support plate 34, so as to flexibly adjust the distance between the support seats 35, realize the transverse limiting of the plate with different sizes, at the same time, the electric push rod 37 at the top of the stand 36 is started, the telescopic end pushes the pressing plate 38 to move downward, and the plate is pressed in the vertical direction, then after the plate is fixed, the upper die structure 4 is controlled by the controller 5, and then the plate is contacted with the fixed plate by the positioning mechanism 3, and the bending operation of the plate is completed by the accurate stroke control and pressure adjustment, in the whole process, the positioning mechanism 3 ensures that the plate is stable and the size is suitable before bending, the upper die structure 4 is responsible for accurate stamping, and the two work together to greatly improve the bending precision and efficiency, and ensure that the metal support parts meet the strict specification requirements, and provide solid and reliable technical support for metal support production.

[0032] Specifically, as shown in Figure 3 The distance structure 39 comprises an electric telescopic rod 391 embedded in the rear side of the frame 1, and the electric telescopic rod 391 is electrically connected with the controller 5.

[0033] Specifically, as shown in Figure 3 The telescopic end of the electric telescopic rod 391 is fixedly connected with a connecting block 392, and the top of the connecting block 392 is fixedly connected with a fixed plate 393.

[0034] Specifically, as shown in Figure 3 The front side of the fixed plate 393 is hinged with a baffle 394, the front side of the baffle 394 is fixedly connected with a distance stop block 395, and the distance stop block 395 is located at the rear side of the top of the rear support plate 34.

[0035] In the embodiment, when the metal support plate is placed on the top of the bearing plate 34, the controller 5 sends a command to the electric telescopic rod 391, and the electric telescopic rod 391 is powered on to extend or shorten the telescopic end, drive the connecting block 392 fixedly connected thereto to move, and drive the fixed plate 393 to move to the preset position, so that the distance block 395 on the rear side of the front side of the fixed plate 393 can accurately abut against the tail end of the plate. According to the telescopic length set by the electric telescopic rod 391, that is, the preset parameter, the position of the tail end of the plate is accurately limited, so that the bending distance of the plate can strictly meet the production requirements each time, the consistency and accuracy of the bending size are greatly improved, and the bending quality of the metal support part is effectively ensured.

[0036] Specifically, as shown in Figure 5 The upper die structure 4 includes a support 41 bolted to the top of the frame 1, and a hydraulic cylinder 42 is arranged on the top side in the support 41.

[0037] Specifically, as shown in Figure 5 The telescopic end of the hydraulic cylinder 42 is fixedly connected with a lifting plate 43, and the bottom of the lifting plate 43 is bolted with an upper die 44, which is located on the top of the lower die 2.

[0038] In the embodiment, when the controller 5 receives the bending command, the hydraulic cylinder 42 on the top side in the support 41 is controlled to work, the telescopic end of the hydraulic cylinder 42 starts to act, drives the lifting plate 43 fixedly connected thereto to move up and down, and the upper die 44 bolted to the bottom of the lifting plate 43 moves synchronously with the lifting plate 43. When bending is needed, the hydraulic cylinder 42 pushes the lifting plate 43 downward, and the upper die 44 approaches and contacts the fixed plate. The hydraulic cylinder 42 can accurately control the output pressure and stroke, apply appropriate pressure according to the characteristics such as the material and thickness of different plates, and control the distance of the upper die 44 downward, so as to complete the accurate plate bending operation, greatly improve the bending precision and efficiency, and ensure that the metal support part meets the strict specification requirements.

[0039] Specifically, as shown in Figure 6 The front side of the frame 1 is provided with an auxiliary support structure 6, and the auxiliary support structure 6 includes an adjusting rod 61 slidingly connected to the front side of the frame 1.

[0040] Specifically, as shown in Figure 6 The front side of the top of the adjusting rod 61 is bolted with an auxiliary support plate 62, and the top of the auxiliary support plate 62 is bonded with a rubber pad 63.

[0041] In this embodiment: by setting the auxiliary support structure 6, when bending the plate, the auxiliary support plate 62 can be manually pulled outward according to the length of the plate and the support requirements, so that the adjusting rod 61 located on the front side of the frame 1 can be moved out and adjusted to a suitable length. In this way, the excessively long plate can be assisted in supporting it. At the same time, the rubber pad 63 glued to the top of the auxiliary support plate 62 can effectively increase the friction with the plate, further ensuring the stability of the plate during the bending process and improving the bending quality.

[0042] Working principle: In the process of using the bending device for metal bracket production, firstly, the metal bracket plate is placed on top of the support plate 34. At this time, the controller 5 sends a command to the electric telescopic rod 391 in the distance-fixing structure 39 on the rear side of the frame 1 according to the preset parameters. The electric telescopic rod 391 starts, and its telescopic end drives the connecting block 392 to move, thereby pushing the fixed plate 393, so that the baffle 394 and the distance-fixing block 395 on the front side of the fixed plate 393 move to the corresponding positions, accurately abutting the tail end of the plate, and determining the bending distance. Then, the motor 32 is turned on, and the output shaft of the motor 32 drives the bidirectional lead screw 31 to rotate. Since the threads on both sides of the lead screw rotate in opposite directions, the moving frame 33 moves along the lead screw in opposite directions, causing the support seat 35 to slide on the outside of the support plate 34, adjusting the spacing to adapt to different sized plates, and completing the lateral limit. At the same time, the upright frame 3... The electric push rod 37 at the top is activated, and the pressure plate 38 presses the plate downward to achieve vertical positioning. After the plate is fixed in place, the controller 5 controls the upper mold structure 4 to work. The hydraulic cylinder 42 on the inner top side of the bracket 41 is activated, and its telescopic end drives the lifting plate 43, causing the upper mold 44 bolted to the bottom to move downward. It cooperates with the lower mold 2 and precisely adjusts the pressure and stroke according to the characteristics of the plate to complete the bending operation. If the plate is too long, the auxiliary support plate 62 can be manually pulled out and the adjusting rod 61 can be extended as needed. In this way, the auxiliary support plate 62 can be adjusted to a suitable position to facilitate auxiliary support for the plate. At the same time, the rubber pad 63 at the top increases the friction with the plate, further assisting in the support of the plate and ensuring the stability of the bending process. The overall components are closely matched, which greatly improves the bending accuracy and efficiency, and produces metal bracket components that meet the specifications.

[0043] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
