[0034] Embodiment:

[0035] Please refer to Figure 1 - Figure 6 , a flattening device for sheet metal processing, including a flattening die 101 provided on a sheet metal die base 1. At one end of the sheet metal die base 1, there are two sets of anti-deviation plates 2 that can extend to the outer wall of the flattening die 101 for positioning. One end of the anti-deviation plate 2 is provided with a groove and is clamped with an anti-slip convex layer 201 that contacts the workpiece.

[0036] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , the flattening device for sheet metal processing of the present application, through the structure of the sheet metal die base 1 and the flattening die 101, enables the flattening die 101 to flatten the bent part of the workpiece located on the sheet metal die base 1. During flattening, the other end of the workpiece is located outside the sheet metal die base 1 and the flattening die 101 and is fixed by the worker. At this time, when the workpiece is placed on the sheet metal die base 1 for flattening operation, by arranging anti-deviation plates 2 for positioning on both sides outside the workpiece, the anti-deviation plates 2 can extend to the outer wall of the flattening die 101. Then, when the flattening die 101 presses down, it can descend along the outer wall of the anti-deviation plates 2, increasing the stability during the application process. The surface of the anti-deviation plate 2 that can contact the side of the workpiece is provided with an anti-slip convex layer 201, and the anti-slip convex layer 201 is designed with a rubber material. Then, when the anti-deviation plate 2 positions, it can further increase the friction force of the contact surface, prevent phenomena such as slipping, and at this time, position the originally accurately placed workpiece to prevent deviation, thus avoiding the problem that the actual position of the workpiece is inconsistent with the expected position, and also improving the subsequent flattening effect.

[0037] In some embodiments, the anti-deviation plate 2 is configured to be bent. One end fixes the workpiece, and the other end can be attached to the outer walls of the sheet metal die base 1 and the flattening die 101. A slot 5 is opened at the end attached to the outer wall of the sheet metal die base 1. A positioning shaft rod 501 is provided on the side of the sheet metal die base 1 and can penetrate through the slot 5. Therefore, when the positioning shaft rod 501 is inserted into the slot 5, the anti-deviation plate 2 can be positioned on the sheet metal die base 1 to ensure stability; the anti-slip convex layer 201 is clamped in the groove of the anti-deviation plate 2 to facilitate replacement in case of subsequent damage.

[0038] It should also be noted that an external thread is provided at one end of the positioning shaft rod 501 extending out of the slot 5. An outer sleeve 502 matching it is threadedly connected to this threaded section to further fix the positioning shaft rod 501. When the outer sleeve 502 is installed, an inner convex ring 503 is glued to the end in contact with the outer wall of the anti-deviation plate 2. The inner convex ring 503 is designed with a rubber material, which can increase the friction of its contact surface and make the connection more stable.

[0039] Please refer to Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 In this application, a bottom frame 3 is also provided on the sheet metal die base 1. The bottom frame 3 is respectively connected to the two anti-deviation plates 2 through an adjustment structure. The adjustment structure is mainly composed of a threaded rotating rod 4 and a sleeve block 401. The threaded rotating rod 4 is respectively installed at the bottom of the bent part of the corresponding anti-deviation plate 2, and its other end can move inside the bottom frame 3. The sleeve blocks 401 are respectively movably installed on both sides of the inner wall of the bottom frame 3 through bearings, and the sleeve blocks 401 are threadedly connected to the threaded part of the threaded rotating rod 4. Then, by rotating the handle of the threaded rotating rod 4, while driving the threaded rotating rod 4 to rotate, it also drives the sleeve block 401 to move left and right on the threaded rotating rod 4, so that the anti-deviation plate 2 moves in the same direction away from or close to one end of the workpiece, and the position of the anti-deviation plate 2 is adjusted according to the processing requirements to facilitate subsequent positioning operations.

[0040] In this application, a chute 6 and a slider 601 are also provided. The chute 6 is opened on both sides at one end of the sheet metal die base 1, and the slider 601 is fixed to the end of the positioning shaft rod 501 facing the chute 6, so that the slider 601 is slidably connected to the inside of the chute 6, and when the overall position of the anti-deviation plate 2 is horizontally adjusted, the slider 601 slides correspondingly inside the chute 6.

[0041] Please refer to Figure 1 and Figure 3, in this application, a plurality of ear plates 7 are further provided. The ear plates 7 are fixedly installed at the bottom of the bottom-mounted frame 3 and are in mutual contact with the outer wall of the sheet metal die base 1. When in contact, the ear plates 7 are fixed to the outer wall of the sheet metal die base 1 by bolts. In this way, the overall installation of the bottom-mounted frame 3 is facilitated for subsequent disassembly and assembly operations. It should also be noted that when the slider 601 slides inside the chute 6, one end of the chute 6 is provided with an opening. During disassembly and assembly, the slider 601 can be slid out from this opening.

[0042] Please refer to Figure 4 and Figure 6 , in this application, a card plug 202 and a card socket 203 are also provided. The card sockets 203 are respectively opened at the four corners of the anti-slip convex layer 201, and the card plugs 202 are installed at the four corners of the groove of the anti-deviation plate 2 and are inserted in matching with the card sockets 203. In this way, when the anti-deviation plate 2 is clamped in the groove of the anti-deviation plate 2, the corresponding card plug 202 is driven to be inserted into the card socket 203 to further ensure the stability of the anti-slip convex layer 201 after installation.

[0043] It should also be noted that the card plug 202 is configured with a large end and a small end. The small end is made of a hard material, and the large end has elasticity. When the small end drives the large end to pass through the inside of the card socket 203, the large end is deformed by extrusion and cooperates. When fully inserted, the extrusion force disappears, so that the anti-slip convex layer 201 can be located between the anti-deviation plate 2 and the large end of the card plug 202, and further limit the connection.

[0044] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the drawings are only examples and do not limit the present invention. The object of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and described in the embodiments. Without departing from the above principles, the embodiments of the present invention can have any deformation or modification.
