Detailed implementation manners

[0019] Embodiment 1

[0020] As Figures 1 to 4 shown, a cold bending forming machine for steel plates proposed by the present utility model includes a frame 1; a cold bending forming mechanism is arranged on the frame 1.

[0021] The cold bending forming mechanism includes an upper rolling rod 2 and a lower rolling rod 3; multiple groups of upper rolling rods 2 are provided, and the multiple groups of upper rolling rods 2 are evenly distributed on the inner side wall of the frame 1. The multiple groups of upper rolling rods 2 are all rotatably connected to the frame 1 and are driven to rotate by a first driving component installed on the outer wall of the frame 1. Multiple groups of upper forming seats 5 are arranged on the outer peripheral surface of the upper rolling rod 2, and the upper forming seats 5 can slide and adjust along the upper rolling rod 2; multiple groups of lower rolling rods 3 are provided, and the multiple groups of lower rolling rods 3 are evenly distributed on the inner side wall of the frame 1. The lower rolling rods 3 correspond to the upper rolling rods 2. The multiple groups of lower rolling rods 3 are all rotatably connected to the frame 1 and are driven to rotate by a second driving component installed on the outer wall of the frame 1. The first driving component and the second driving component have the same structure and are both composed of a motor-driven chain transmission component. The chain transmission component is arranged between the multiple groups of upper rolling rods 2 or the multiple groups of lower rolling rods 3. Multiple groups of lower forming seats 6 are arranged on the outer peripheral surface of the lower rolling rod 3, and the lower forming seats 6 can slide and adjust along the lower rolling rod 3. The lower forming seats 6 correspond to the upper forming seats 5, and the lower forming seats 6 and the upper forming seats 5 cooperate with each other to cold press the steel plate into different shapes.

[0022] Furthermore, an annular seat is arranged on the side wall of the upper forming seat 5. The annular seat is slidably connected to the upper rolling rod 2. A fixing rod 501 is installed on the annular seat. An L-shaped rod 503 is slidably connected to the fixing rod 501. Multiple groups of first slots 201 are formed on the upper rolling rod 2. The first slots 201 are inserted with the L-shaped rod 503. The other end of the L-shaped rod 503 is inserted into the upper rolling rod 2. An elastic member 502 is further sleeved outside the fixing rod 501. The elastic member 502 is a spring. The top end of the elastic member 502 is fixedly connected to the top end of the fixing rod 501, and the bottom end of the elastic member 502 is fixedly connected to the L-shaped rod 503.

[0023] Further, a connecting seat 601 is installed on the lower forming seat 6. The connecting seat 601 is slidably connected to the lower rolling rod 3, and the connecting seat 601 and the lower rolling rod 3 are limitedly connected by bolts. A chute 301 is formed on the lower rolling rod 3, and a plurality of groups of second slots 302 are formed at the bottom end of the chute 301. The connecting seat 601 is slidably connected to the second slots 302, and the bolts on the connecting seat 601 are threadedly connected to the second slots 302. The arrangement of the second slots 302 and the connecting seat 601 not only facilitates the limitation of the lower forming seat 6 and the lower rolling rod 3, but also prevents the lower forming seat 6 from rotating along the lower rolling rod 3 and interfering with the connection between the connecting seat 601 and the lower rolling rod 3.

[0024] In this embodiment, the hand-held L-shaped rod 503 slides upward along the fixed rod 501, so that the elastic member 502 is compressed. Further, the insertion end of the L-shaped rod 503 is far away from the upper rolling rod 2. At this time, the upper forming seat 5 loses the limitation with the upper rolling rod 2. According to the cold pressing requirement of the steel plate, the upper forming seat 5 is slid horizontally along the upper rolling rod 2 to any position. Then, the L-shaped rod 503 is released. Under the action of the elastic recovery of the elastic member 502, the insertion end of the L-shaped rod 503 is driven to insert into the corresponding first slot 201 on the upper rolling rod 2, and the limitation between the upper forming seat 5 and the upper rolling rod 2 can be completed again, avoiding the displacement of the upper forming seat 5 during the cold pressing process and interfering with the forming; when the upper forming seat 5 slides and adjusts along the upper rolling rod 2, the bolt between the connecting seat 601 and the second slot 302 is removed, so that the lower forming seat 6 moves simultaneously with the upper forming seat 5 until the lower forming seat 6 slides to an appropriate position along the lower rolling rod 3. After the adjustment of the upper forming seat 5 is completed, the connecting seat 601 and the corresponding second slot 302 are fixedly connected by bolts. Then, the ground driving assembly and the second driving assembly are started, and a plurality of groups of upper rolling rods 2 and a plurality of groups of lower rolling rods 3 can be driven to rotate, and further drive a plurality of groups of upper forming seats 5 and a plurality of groups of lower forming seats 6 to rotate to roll and form the steel plate. By sliding and adjusting the upper forming seat 5 and the lower forming seat 6 along the upper rolling rod 2 and the lower rolling rod 3 respectively, it is convenient to adjust the distance between adjacent cold bending parts on the steel plate according to the need, and then cold bend the steel plate into different shapes, making the use more flexible.

[0025] Embodiment 2

[0026] As Figure 2 and Figure 3 shown, a steel plate cold bending forming machine proposed by the present utility model, compared with Embodiment 1, two sets of adjusting seats 7 are symmetrically and slidably connected to the frame 1. Both ends of the adjusting seat 7 are threadedly connected with second screw rods 701. The second screw rods 701 are rotatably connected to the frame 1, and a scale corresponding to the adjusting seat 7 is arranged on the side wall of the frame 1.

[0027] Further, the upper rolling rod 2 is rotatably connected between two sets of adjusting seats 7. The first driving assembly is installed on the side wall of one set of adjusting seats 7. A first disassembly and assembly component is rotatably connected to the other set of adjusting seats 7. The first disassembly and assembly component is composed of a rotating cylinder 4 rotatably connected to the adjusting seat 7 and a plug rod 401 that penetrates and slidably connects through the rotating cylinder 4. A first screw rod 402 is installed between the plug rod 401 and the rotating cylinder 4. The plugging end of the plug rod 401 is plugged into the end of the upper rolling rod 2 that is far from the first driving assembly.

[0028] Furthermore, a second disassembly and assembly component is detachably installed at the end of the lower rolling rod 3 that is far from the second driving assembly. The second disassembly and assembly component is rotatably connected to the frame 1, and the second disassembly and assembly component has the same structure as the first disassembly and assembly component.

[0029] In this embodiment, by removing the first screw rod 402 between the rotating cylinder 4 and the plug rod 401 and sliding the plug rod 401 along the rotating cylinder 4, the plugging end of the plug rod 401 is separated from the upper rolling rod 2, and the upper forming seat 5 on the upper rolling rod 2 can be replaced with a different model. Replace the upper and lower forming seats 6 on the lower rolling rod 3 in the same way to correspond to the upper forming seat 5. At the same time, by rotating the second screw rod 701 to drive the adjusting seat 7 to slide up and down along the frame 1, the upper forming seat 5 and the lower forming seat 6 are made to correspond, which is convenient for cold-bending steel plates of different models, the adjustment is convenient and fast, and the applicable range is wider.

Various changes can be made without departing from the spirit of the present invention within the knowledge scope of those skilled in the art to which the present invention pertains.
