[0002] A bending machine die is a tool used by a bending machine to form and process sheet materials, and is often used for processing sheet metal parts. When the current bending machine die is in use, the hydraulic cylinder reciprocates to perform sheet metal bending processing. The hydraulic transmission pressure is strong, but during a large number of bending operations, it is necessary to control the continuous reciprocating telescoping of the hydraulic cylinder, and the transmission speed is slow, resulting in low production efficiency. Summary of the Utility Model

[0003] The technical problem to be solved by the utility model is the slow transmission speed of the hydraulic cylinder bending processing.

[0004] To solve the above problems, the following technical solutions are adopted in the utility model: The sheet metal multi-fold bending arc die proposed by the utility model includes a base, an upper template, and a lower template. An installation frame is fixedly provided on the upper part of the base, and a vertical plate is fixedly provided at the rear of the base. It also includes a blanking mechanism and a transmission mechanism. The blanking mechanism is arranged on the upper part of the vertical plate, and the transmission mechanism is arranged on the upper part of the installation frame. The transmission mechanism includes a driving shaft, a connecting shaft, a limiting shaft, and a slider. A motor is provided on the side of the installation frame. One end of the driving shaft is rotatably connected to the inner side of the installation frame and penetrates through the installation frame. The driving shaft is shaft-connected to the motor shaft. One end of the connecting shaft is rotatably connected to the other end of the driving shaft. The other end of the connecting shaft is rotatably connected to one end of the limiting shaft. The other end of the limiting shaft is fixedly provided with a slider. A chute is opened on the front side of the installation frame. The slider is slidably connected to the chute and penetrates through the chute.

[0005] Further, the upper template is fixedly connected to the lower end of the slider. The lower template is arranged on the upper part of the base, and the upper template and the lower template are in a fitting connection.

[0006] Further, the blanking mechanism includes a hydraulic cylinder. The fixed end of the hydraulic cylinder is fixedly connected to the vertical plate. The movable end of the hydraulic cylinder is slidably connected to the vertical plate and penetrates through the vertical plate. A push rod is fixedly connected to the movable end of the hydraulic cylinder. The push rod is slidably connected to the upper part of the lower template.

[0007] Further, a blanking plate is fixedly connected to the other end of the base away from the vertical plate. The blanking plate is provided with a slope-like structure.

[0008] The beneficial effects obtained by the utility model adopting the above structure are as follows:

[0009] For the sheet metal multi-fold bending arc die proposed in this scheme, by driving the driving shaft to rotate through the motor, under the transmission and limitation of the connecting shaft and the limitation of the chute, the sheet metal bending and forming of metal parts can be completed directly by driving the motor, without adjusting the rotation direction of the motor, and the processing efficiency is high.

[0015] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the attached drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments; based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0016] As Figure 1 and Figure 3 shown, the sheet metal multi-fold bending arc die proposed by the present utility model includes a base 1, an upper template 4 and a lower template 5. An installation bracket 101 is fixedly provided on the upper part of the base 1, a vertical plate 102 is fixedly provided on the rear part of the base 1, and further includes a discharging mechanism 2 and a transmission mechanism 3. The discharging mechanism 2 is arranged on the upper part of the vertical plate 102, the transmission mechanism 3 is arranged on the upper part of the installation bracket 101. The transmission mechanism 3 includes a driving shaft 302, a connecting shaft 303, a limiting shaft 304 and a slider 305. A motor 301 is arranged on the side of the installation bracket 101. One end of the driving shaft 302 is rotatably connected to the inner side of the installation bracket 101 and penetrates through the installation bracket 101. The driving shaft 302 is shaft-connected to the motor 301. One end of the connecting shaft 303 is rotatably connected to the other end of the driving shaft 302. The other end of the connecting shaft 303 is rotatably connected to one end of the limiting shaft 304. The other end of the limiting shaft 304 is fixedly provided with a slider 305. A sliding groove 306 is opened on the front side of the installation bracket 101. The slider 305 is slidably connected to the sliding groove 306 and penetrates through the sliding groove 306.

[0017] As Figure 1 and Figure 2 shown, the upper template 4 is fixedly connected to the lower end of the slider 305. The lower template 5 is arranged on the upper part of the base 1. The upper template 4 and the lower template 5 are in a fitting connection. The discharging mechanism 2 includes a hydraulic cylinder 201. The fixed end of the hydraulic cylinder 201 is fixedly connected to the vertical plate 102. The movable end of the hydraulic cylinder 201 is slidably connected to the vertical plate 102 and penetrates through the vertical plate 102. A push rod 202 is fixedly connected to the movable end of the hydraulic cylinder 201. The push rod 202 is slidably connected to the upper part of the lower template 5 and is used to push out the metal parts formed by sheet metal bending. The other end of the base 1 away from the vertical plate 102 is fixedly connected with a blanking plate 203. The blanking plate 203 is arranged in a slope structure to facilitate the sliding of the pushed-out metal parts and reduce the damage caused by their direct vertical dropping to the ground.

[0018] During specific use, the original parts to be formed by sheet metal bending are placed on the upper part of the lower template 5. The motor 301 is started to rotate the driving shaft 302 to drive the connecting shaft 303 to rotate. Under the limitation of the connecting shaft 303 and the transmission and the limiting effect of the chute 306, the limiting shaft 304 drives the slider 305 to reciprocate up and down. During the up and down movement stroke of the slider 305, the upper template 4 and the lower template 5 are driven to cooperate to bend the metal original parts into shape. Through the drive of the motor 301, the reciprocating stroke processing can be completed without adjusting the rotation direction of the motor 301. While the upper template 4 moves upward after the processing is completed, the hydraulic cylinder 201 is controlled to extend to drive the push rod 202 to move, so that the formed parts on the lower template 5 can be quickly pushed out. With the cooperation of the transmission mechanism 3, the sheet metal can be continuously pushed out, and the processing efficiency is high.

[0019] The above describes the present invention and its implementation manners. This description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present invention, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and without departing from the gist of the creation of the present invention, they design similar structural manners and embodiments to this technical solution without creative efforts, and all should belong to the protection scope of the present invention.
