[0003] In existing automated sheet metal bending and forming equipment, the lower die used for bending sheet metal parts needs to be changed frequently when facing the production needs of small batches and multiple varieties. In addition, during the sheet metal bending production process, some sheet metal parts need to be bent multiple times with different dies. Each time a different shape is bent, a different die needs to be used. The die switching operation is too complicated, which greatly reduces the production efficiency of sheet metal bending and forming. Therefore, an automated sheet metal bending and forming equipment is proposed to solve the above problems. Utility Model Content

[0029] 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.

[0030] Reference Figure 1 , Figure 2 , Figure 3 This utility model provides an embodiment of an automated sheet metal bending and forming equipment, including a housing 1 for mounting other components. A mounting frame 2 for driving the upper mold 3 to move during extrusion is mounted on the upper surface of the housing 1. An upper mold 3 for cooperating with a lower mold 4 to bend sheet metal parts is mounted on the inner wall of the mounting frame 2. A rotation groove 9 for limiting the fixed rod 5 is provided on the inner wall of the housing 1. A mold changing mechanism is provided on the inner wall of the housing 1, which facilitates the replacement of different lower molds 4. The mold changing mechanism includes a disassembly and installation component and a rotation switching component. The rotation switching component includes a rotating rod 7 for driving the lower mold 4 to rotate and change. The rotating rod 7 is rotatably connected to the inner wall of the housing 1, and the housing 1 supports the rotating rod 7. A placement rod 6 for mounting the lower mold 4 is fixedly connected to the outer wall of the rotating rod 7. A lower mold 4 for bending sheet metal parts is provided on the outer wall of the placement rod 6. A fixing rod 5 for fixing the lower mold 4 to the placement rod 6 is provided on the outer wall of the lower mold 4. Extension rods 11 for supporting and stabilizing the fixing rod 5 are fixedly connected to both ends of the fixing rod 5.

[0031] Reference Figure 2 , Figure 3 , Figure 4The disassembly and installation assembly includes a limiting rod 13 for sealing the rotating groove 9. The limiting rod 13 is slidably connected to the inner wall of the housing 1. The space created by the sliding of the limiting rod 13 allows the extension rod 11 to enter. After the extension rod 11 enters, it will drive the fixing rod 5 to disengage from the surface of the lower mold 4, thereby releasing the fixation on the lower mold 4. A fixing block 12 for keeping the limiting rod 13 stable is fixedly connected to the rear surface of the limiting rod 13. A plug rod 15 for fixing the fixing block 12 is inserted into the inner wall of the fixing block 12. A pressing handle 8 is rotatably connected to the inner wall of the limiting rod 13. When the pressing handle 8 is pressed down and rotated, it uses the lever principle to push the limiting rod 13 to move backward. The limiting rod 13 and the housing 1 are elastically connected by a spring 14. The spring 14 provides elastic force for the limiting rod 13 to seal the rotating groove 9.

[0032] Reference Figure 3 , Figure 4 A magnet 16 is fixedly connected to the inner wall of the lower mold 4. Magnet 16 and magnet 2 17 attract each other, allowing for quick positioning of the lower mold 4. A magnet 2 17 is fixedly connected to the inner wall of the placement rod 6. A motor 10 for driving the rotating rod 7 is installed on the inner wall of the housing 1. The output shaft of the motor 10 is fixedly connected to the left end of the rotating rod 7. The extension rod 11 slides on the inner wall of the rotating groove 9, allowing the fixed rod 5 to maintain pressure on the lower mold 4. One end of the spring 14 is fixedly connected to the right surface of the limiting rod 13, and the other end of the spring 14 is fixedly connected to the inner wall of the housing 1. The housing 1 provides support for the spring 14. The limiting rod 13 is Z-shaped. A pressing handle 8 is installed on the top of the limiting rod 13. A protrusion is provided on the lower surface of the pressing handle 8 to prevent pinching the hand when pressing down. The fixed rod 5 is L-shaped, allowing for simultaneous pressing and restriction of two sets of lower molds 4. The placement rod 6 is rectangular, making the installed lower mold 4 more stable.

[0033] Working principle: During use, when the lower mold 4 needs to be replaced, the operator starts the motor 10. The motor 10 drives the rotating rod 7 to rotate, which in turn drives the lower mold 4 mounted on the placement rod 6 to rotate. As the lower mold 4 rotates, the fixing rod 5 is restricted by the extension rod 11. The extension rod 11 slides on the inner wall of the rotating groove 9, allowing the fixing rod 5 to rotate while maintaining the compression and fixation of the lower mold 4. This ensures that the device can quickly switch to the required lower mold 4, improving the processing efficiency of the device when facing different bending requirements. If it is necessary to replace the mold on the placement rod 6, the operator can pull out the insertion rod 15 and then operate the extrusion handle 8. The middle part is rotatably connected to the top of the limiting rod 13. The squeezing handle 8 uses the lever principle to pry the limiting rod 13 backward. When the limiting rod 13 moves, it creates a notch in the rotating groove 9. At this time, the fixing rod 5 is pushed to allow the extension rod 11 to enter it, releasing the fixation of the lower mold 4. The lower mold 4 is then removed from the placement rod 6, and other lower molds 4 are installed. During installation, magnet 16 and magnet 2 17 attract each other, allowing the lower mold 4 to be quickly positioned and preventing the lower mold 4 from sliding left and right and affecting the installation. Then, the squeezing handle 8 is pulled upward to allow the spring 14 to push the limiting rod 13 and the extension rod 11 back to their original positions. The insert rod 15 is then inserted to complete the fixation, making it convenient to replace the lower mold 4.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
