Description

Technical Field

[0001] This utility model relates to the field of bending machine technology, and in particular to a bending machine with a detachable bending head. Background Technology

[0002] A bending machine is a machine that can bend thin plates. By using different bending dies, the bending machine can achieve different bending effects on the plates.

[0003] Currently, bending machines use multiple clamping mechanisms to hold bending dies, which means that the clamping mechanisms need to be loosened sequentially during disassembly, which is time-consuming.

[0004] A publicly available technical solution, CN213378617U, discloses a bending machine, including a frame, a base on the frame, a bending base on the base, and a sliding column that is vertically mounted on the frame. Multiple clamping mechanisms are located at the end of the sliding column near the bending base, and a bending cutter is detachably mounted at the end of each clamping mechanism near the bending base. Each clamping mechanism has a clamping rod rotatably mounted for controlling the clamping operation. A rotating rod is rotatably mounted at the end of each clamping rod away from the clamping mechanism, and an operating rod is located at the end of each rotating rod away from the clamping rod. The operating rod connects to the multiple rotating rods. By rotatably mounting rotating rods at the ends of the clamping rods away from the clamping mechanism, and operating rods at the ends of the rotating rods away from the clamping rods, and connecting multiple rotating rods to the operating rods, when changing the bending cutter on the bending machine, the operating rod is moved, causing the clamping rods on the clamping mechanisms to rotate, allowing the clamping mechanisms to contact and clamp the bending cutter, thus facilitating the change of the bending cutter.

[0005] In actual implementation, the above technical solution involves directly loosening all clamping mechanisms. Since the bending die has a certain weight, this can easily injure workers. To avoid this, the upper die is usually lowered when disassembling it, so that the bending upper die is aligned with the bending lower die slot, and the lower die is used to support the upper die. However, when transferring the upper die later, it is necessary to separate the upper die and the lower die again. If the upper die falls, it can easily injure workers. Summary of the Invention

[0006] The purpose of this utility model is to provide a bending machine with a detachable bending head, which can support the upper die during disassembly. This not only facilitates the subsequent transfer of the upper die, but also prevents the upper die from accidentally falling and injuring workers during disassembly, thereby solving the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a bending machine with a detachable bending head, comprising a bending machine body, wherein a plurality of equally spaced and uniformly distributed clamps are detachably connected to the front end of the bending machine body, and an upper bending die is installed inside the clamps; a transmission component is provided at the front end of the clamps; a movable upper die support component is installed below the upper bending die; and a lower bending die adapted to the upper bending die is provided below the upper die support component.

[0008] The upper mold support assembly includes a hydraulic cylinder fixed to the rear end of the bending machine body, and the telescopic end of the hydraulic cylinder passes through the interior of the bending machine body and is fixedly connected to a bottom support plate. The bottom support plate has several equally spaced and evenly distributed support grooves inside. The support grooves are U-shaped and the openings of the support grooves are located on the front end face of the bottom support plate.

[0009] Preferably, a limit baffle is vertically fixed to the top of the bottom support plate, and a rotating plate is rotatably connected to the front end of the bottom support plate, with a rotating shaft provided at the connection between the rotating plate and the bottom support plate.

[0010] Preferably, connecting rods are provided on the left and right sides of the rotating plate and the bottom support plate, with one end of the connecting rod rotatably mounted on the rotating plate and the other end of the connecting rod rotatably mounted on a limit slide rod.

[0011] Preferably, a guide groove is provided at the connection between the limiting slide rod and the bottom support plate, and an electromagnet is fixedly provided at the rear end of the guide groove, wherein the electromagnet and the iron limiting slide rod are magnetically attracted.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides a technical solution:

[0026] Please see Figures 1 to 4A bending machine with a detachable bending head includes a bending machine body 1. A plurality of equidistant and evenly distributed clamps 3 are detachably connected to the front end of the bending machine body 1. A bending upper die 5 is installed inside the clamps 3. A transmission component 2 is provided at the front end of the clamps 3. A movable upper die support component 4 is installed below the bending upper die 5. A bending lower die adapted to the bending upper die 5 is provided below the upper die support component 4.

[0027] The upper die support assembly 4 includes a hydraulic cylinder 401 fixed to the rear end of the bending machine body 1, and the telescopic end of the hydraulic cylinder 401 passes through the interior of the bending machine body 1 and is fixedly connected to a bottom support plate 407. The bottom support plate 407 has several equally spaced and evenly distributed support grooves 410 inside. The support grooves 410 have a U-shaped structure and the openings of the support grooves 410 are located on the front end face of the bottom support plate 407.

[0028] By adopting the above technical solution, when it is necessary to disassemble the upper bending die 5, the hydraulic cylinder 401 can push the bottom support plate 407 forward to move below the upper bending die 5, thereby supporting the upper bending die 5 and preventing the upper bending die 5 from slipping and injuring workers. At the same time, the U-shaped support groove 410 facilitates the insertion of forklifts. After the upper bending die 5 is disassembled, it is convenient to transfer the upper bending die 5.

[0029] Specifically, such as Figure 2 As shown, a limit baffle 402 is vertically fixed to the top of the bottom support plate 407, and a rotating plate 403 is rotatably connected to the front end of the bottom support plate 407. A rotating shaft 405 is provided at the connection between the rotating plate 403 and the bottom support plate 407. Connecting rods 404 are provided on the left and right sides of the rotating plate 403 and the bottom support plate 407. One end of the connecting rod 404 is rotatably mounted on the rotating plate 403, and the other end of the connecting rod 404 is rotatably mounted on a limit slide rod 406. A guide groove 408 is provided at the connection between the limit slide rod 406 and the bottom support plate 407, and an electromagnet 409 is fixedly provided at the rear end of the guide groove 408. The electromagnet 409 and the iron limit slide rod 406 are magnetically attracted to each other.

[0030] By adopting the above technical solution, the hydraulic cylinder 401 pushes the bottom support plate 407 forward. To facilitate the forklift transfer of the bending upper die 5, the thickness of the rotating plate 403 is less than the thickness of the bottom support plate 407, and their tops are on the same horizontal plane. After the limiting baffle 402 is in contact with the rear side of the bending upper die 5, the rotating plate 403 is rotated. At this time, the rotating plate 403 moves upward through the rotating shaft 405. To prevent the rotating plate 403 from rotating downward, a baffle is set at the bottom of the rotating plate 403 for support. The baffle is fixed on the bottom support plate 407. Meanwhile, the two ends of the connecting rod 404 rotate in cooperation with the rotating plate 403 and the limiting slide rod 406 respectively. At the same time, the limiting slide rod 406 slides backward inside the guide slide groove 408. After the electromagnet 409 is energized, it can attract the iron limiting slide rod 406, thereby locking the limiting slide rod 406. At this time, the bending upper die 5 is located in the space formed by the rotating plate 403, the bottom support plate 407 and the limiting baffle 402, which limits the bending upper die 5. When the rotating plate 403 and the bottom support plate 407 form a 90° angle, the front end of the support groove 410 can be completely exposed.

[0031] Specifically, such as Figure 3 and Figure 4 As shown, the transmission assembly 2 includes a support plate 202 parallel to the clamp 3, and a transmission rod 201 is rotatably mounted on the front end of the support plate 202. The transmission rod 201 has an internal hexagonal slot, and a drive sprocket 203 is fixedly connected to the end of the transmission rod 201. A transmission chain belt 204 is provided on the outside of the drive sprocket 203. A passive sprocket 205 is also provided inside the transmission chain belt 204 and meshes with the transmission chain belt 204. A hexagonal screw 206 is fixedly connected to the middle of the passive sprocket 205, and an internal hexagonal screw 6 that is compatible with the hexagonal screw 206 is threaded inside the clamp 3. The end of the internal hexagonal screw 6 abuts against the bending upper die 5.

[0032] By adopting the above technical solution, after supporting the bending upper die 5, a tool is used to drive the transmission rod 201 to rotate. The transmission rod 201 can drive the transmission chain belt 204 through the driving sprocket 203. The transmission chain belt 204 can then drive all the driven sprockets 205 to rotate. After the driven sprockets 205 rotate, the hexagonal rod 206 will rotate. Since the hexagonal rod 206 is inserted into the interior of the internal hexagonal screw 6 and is movably connected to the internal hexagonal screw 6, it will not detach from the hexagonal rod 206. At this time, as the hexagonal rod 206 rotates, it can drive the internal hexagonal screw 6 to rotate, so that the internal hexagonal screw 6 moves away from the bending upper die 5. This structure can also be replaced by a quick clamp device to achieve quick disassembly of the bending upper die 5.

[0033] Working principle: When the upper bending die 5 needs to be disassembled, the hydraulic cylinder 401 pushes the bottom support plate 407 forward. To facilitate the transfer of the upper bending die 5 by forklift, the thickness of the rotating plate 403 is less than the thickness of the bottom support plate 407, and the tops of both are on the same horizontal plane. After the limiting baffle 402 is attached to the rear side of the upper bending die 5, the rotating plate 403 is rotated. At this time, the rotating plate 403 moves upward through the rotating shaft 405. To prevent the rotating plate 403 from rotating downward, a baffle is set at the bottom of the rotating plate 403 for support. The baffle is fixed on the bottom support plate 407. While the rotating plate 403 rotates, the two ends of the connecting rod 404 rotate in cooperation with the rotating plate 403 and the limiting slide rod 406, respectively. At the same time, the limiting slide rod 406 rotates in the guide groove 408. When the internal part of the upper die 406 slides backward, the electromagnet 409 is energized and can attract the iron limiting slide rod 406, thereby locking the limiting slide rod 406. At this time, the upper bending die 5 is located in the space formed by the rotating plate 403, the bottom support plate 407 and the limiting baffle 402, which limits the upper bending die 5. When the rotating plate 403 and the bottom support plate 407 form a 90° angle, the front end of the support groove 410 can be completely exposed. The forklift is inserted under the bottom support plate 407 along the direction of the support groove 410. When it is necessary to transfer the upper bending die 5, the forklift passes through the support groove 410 and is close to the upper bending die 5. After lifting the upper bending die 5, the upper die support assembly 4 is reset, so that the upper die support assembly 4 and the upper bending die 5 are separated from each other. At this time, the upper bending die 5 is located on the forklift.

Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
