A first clearance groove 3122 for avoiding the bending part is provided on the side wall of the first knife table 312 facing the first limiting block 22. When the bending is in place, the bending part on the left forming position 60 or the right forming position 61 is in close contact with the first clearance groove 3122.

[0042] In this embodiment, the first tool rest 312 includes a fixed part 312 fixedly disposed in the working groove 21, and a movable part 3121 slidably disposed on the fixed part 312. A first clearance groove 3122 is disposed on the side wall of the fixed part 312 away from the movable part 3121. A guide block 24 is provided on the side of the first tool rest 312 away from the first limiting block 22. A bending space 25 for inserting the first bending punch 310 is provided between the guide block 24 and the movable part 3121. A second clearance groove 3123 is provided on the side wall of the movable part 3121 facing the guide block 24 to allow the clearance of ...

[0043] It is worth noting that the two support legs 51 on the left forming position 60 or the right forming position 61 are formed in one step, that is, there are two first bending punches 310, and they are respectively set to correspond to the positions of the two support legs 51 on the left forming position 60 or the right forming position 61.

[0044] In this embodiment, a first support rod 11 is vertically arranged inside the lower mold base 2, and the upper end of the first support rod 11 is fixedly connected to the lower surface of the movable part 3121; a first buffer member 12 is vertically arranged below the first support rod 11, and the upper end of the first buffer member 12 is fixedly connected to the lower end of the first support rod 11. The first buffer member 12 absorbs the impact, thereby extending the mold life and ensuring the smooth reset of the movable part 3121.

[0045] The first buffer element 12 is an SWB mold spring.

[0046] In this embodiment, the bending mechanism of the mounting plate 52 also includes a support leg 51 pre-bending punch 301, a bending portion pre-bending punch 300, and a third tool holder 302; the support leg 51 pre-bending punch 301 and the bending portion pre-bending punch 300 are both located on the lower surface of the upper die base 1, and both pass through the pressure plate 10 and are slidably connected to the pressure plate 10.

[0047] The third tool rest 302 is located in the working groove 21. The working groove 21 is provided with a second limiting block 26 to limit the bending part pre-bending punch 300. A bending part pre-bending space 27 for the bending part 53 pre-bending punch to be inserted is provided between the second limiting block 26 and the third tool rest 302. The first limiting block 22 is located on the side of the third tool rest 302 away from the second limiting block 26. A third clearance groove 3020 for the bending part is provided on the side wall of the third tool rest 302 facing the second limiting block 26. A tool rest surface 3021 adapted to the pre-bending punch 301 of the support leg 51 is provided on the side wall of the third tool rest 302 away from the third clearance groove 3020.

[0048] The pre-bending assembly 3130 consists of a pre-bending punch 300 for the bending section, a pre-bending punch 301 for the support leg 51, and a third guide plate 302. This assembly is used to complete the 45-degree pre-bending of the bending section and the support leg 51. The bending assembly 31 consists of a first bending punch 310, a bending punch 311 for the bending section, and a first guide plate 312. This assembly is used to complete the 90-degree bending of the bending section and the support leg 51. The 45-degree pre-bending first plasticizes the bending section and the support leg 51 as a whole, which can significantly reduce the risk of springback and cracking during subsequent bending, reduce the torque required for final bending, and make the material flow evenly and the fold line stable. This assembly has good practicality.

[0049] Furthermore, the pressure plate 10 is provided with through holes 100 for accommodating the first bending punch 310, the second bending punch 40, the bending block 41, the bending part bending punch 311, the bending part pre-bending punch 300, and the support leg 51 pre-bending punch 301; when the upper die base 1 descends, it will drive the pressure plate 10 to descend together until the lower surface of the pressure plate 10 abuts against the sheet metal; at this time, the first bending punch 310 and the second bending punch 40... The bending block 41, bending punch 311, bending pre-bending punch 300, and support leg 51 pre-bending punch 301 will extend from their corresponding receiving slots; for example, the first bending punch 310 will be inserted into the bending space 25 of the support leg 51, and the first bending forming ball 313 will roll along the side wall of the movable part 3121 to press the support leg 51 down to ninety degrees to complete the bending; other bending punches will also extend into their corresponding bending spaces to achieve bending.

[0050] In this embodiment, a first bending forming ball 313 is provided on the punch end of the first bending punch 310 with a fixed axis and rolling motion. The first bending forming ball 313 is located on the side wall opposite to the movable part 3121 of the punch end of the first bending punch 310. A second bending forming ball 43 is provided on the punch end of the second bending punch 40 with a fixed axis and rolling motion. The second bending forming ball 43 is positioned towards the second tool rest 42. By providing the first and second bending forming balls 43 with a fixed axis and rolling motion at the punch ends of the first and second bending punches 40, respectively, and ensuring that the balls always face the side wall of the movable part 3121 or the corresponding tool rest, sliding friction can be transformed into rolling friction, significantly reducing forming resistance and the risk of scratches. At the same time, the balls adaptively roll with the workpiece surface, resulting in uniform force and a more stable bending line, thereby improving forming accuracy and surface quality.

[0051] In this embodiment, above the working groove 21, along the length of the lower mold base 2, there are sequentially arranged a first working position 13 and a second working position 14 for forming the left forming position 60 and the right forming position 61 in a working unit 6, respectively. There are two of each of the following: a first tool holder 312, a third tool holder 302, a support leg 51 pre-bending punch 301, a bending part pre-bending punch 300, a first limiting block 22, a second limiting block 26, and a guide block 24, arranged opposite each other on the first working position 13 and the second working position 14. The arrangement of the first working position 13 and the second working position 14 allows for the simultaneous forming of parts from the left forming position 60 and the right forming position 61 in one operation, reducing the number of position changes, accelerating the production cycle, and increasing the production rate.

[0052] In this embodiment, there are two bending blocks 41, which are arranged opposite each other along the width direction of the lower die base 2. The two bending blocks 41 are respectively located above the two support plates 50 in a working unit 6, and the side wall of the bending block 41 away from the other bending block 41 is aligned with the connection between the support plate 50 and the mounting plate 52. The second bending punch 40 is respectively set on the two side walls of the second tool holder 42 corresponding to the two bending blocks 41. When the bending is in place, the second bending punch 40 is set close to the side wall of the bending block 41 away from the other bending block 41.

[0053] In this embodiment, a second support rod 15 is vertically provided inside the lower mold base 2, and the upper end of the second support rod 15 is fixedly connected to the lower surface of the second tool rest 42. In the initial state, there is a height difference between the lower surface of the second tool rest 42 and the working groove 21, and a second buffer 16 is vertically provided at the lower end of the second support rod 15. The second buffer 16 is also an SWB mold spring.

[0054] During operation, the two bending blocks 41 press down, pressing the second tool holder 42 against the bottom surface of the working groove 21, and aligning the outer walls of the two bending blocks 41, which are far apart from each other, with the connection between the support plate 50 and the mounting plate 52. As the second tool holder 42 descends, the second bending punch 40 rises relative to the second tool holder 42, using the second bending forming ball 43 to bend the mounting plate 52 on the workpiece along the side wall of the bending blocks 41, thus completing the forming of the mounting plate 52. The symmetrically arranged bending blocks 41 and the second bending punches 40 on both sides of the second tool holder 42 can simultaneously complete the forming of the left and right parts in one operation, improving production efficiency.

[0055] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
