The machine base is provided with a table corresponding to the material guide wheel group, and the material guide wheel group is arranged on the table. Through the feeding and pressing mechanism, it can also perform pressing operation on the sheet metal, and through multiple groups of pressing roller groups, the flat sheet metal is progressively bent into the set curve rate and / or folding edge.

[0004] In the process of realizing the utility model, the inventors found that there are at least the following problems in the prior art that have not been solved: in the above case, although the sheet material can be pre-pressed during use, it is not convenient to control the pre-pressure degree. If the pre-pressure is too small or too large, it will affect the use effect. In addition, during the use of the circle making machine, it is necessary to pre-press sheets of different widths according to the use requirements. There is no corresponding sheet limiting device, and the sheet material is prone to tilt.

[0018] See also Figure 1-Figure 2 The utility model provides a technical solution: a circle making machine with sheet metal pre-pressing function, including a circle making machine body 1, a conveying frame 11 is welded on the upper side of one side of the circle making machine body 1, and also includes an adjusting frame 12, a connecting block 16, a pressure sensor 17 and a limit plate 2. The adjusting frame 12 is slidably connected to the upper inner side of the conveying frame 11, a pre-pressing roller 13 is rotatably connected to the inner side of the adjusting frame 12, and an electric roller 14 is rotatably connected to the lower inner side of the conveying frame 11. A limiting groove 15 is provided in the middle of the upper surface of the adjusting frame 12, and an electro-hydraulic push rod 18 is fixedly connected to the upper surface of the conveying frame 11, and the telescopic end of the electro-hydraulic push rod 18 is fixedly connected to the middle of the upper surface of the connecting block 16.

[0019] In this technical solution, the electro-hydraulic push rod 18 is controlled by the corresponding controller to work, and the pre-pressing roller 13 on the inner side of the adjusting frame 12 can be pushed downward through the connecting block 16, so that the sheet material on the inner side of the conveying frame 11 can be pre-pressed through the electric roller 14. It should be noted that the electric roller 14 is evenly installed on the inner side of the conveying frame 11, and the electric roller 14 corresponds to the pre-pressing roller 13 one by one.

[0020] In this embodiment, limit rods 19 are vertically fixedly installed on both sides of the upper surface of the connecting block 16. The limit rods 19 pass through the top inner wall of the conveying frame 11 and are slidably connected to the conveying frame 11. The bottom end of the connecting block 16 is clamped on the inner side of the limit groove 15, and the pressure sensor 17 is fixedly connected to the bottom inner wall of the limit groove 15.

[0021] In this technical solution, the movement stability of the pre-pressing roller 13 inside the adjustment frame 12 can be improved by the limit rod 19, the pressure of the connecting block 16 can be detected by the pressure sensor 17, and the pressure of the pre-pressing roller 13 on the sheet material can be further detected. When the pressure of the pre-pressing roller 13 on the sheet material reaches the threshold of the pressure sensor 17, the pressure sensor 17 can transmit the data to the corresponding controller, and the corresponding controller can further automatically control the electro-hydraulic push rod 18 to stop working, thereby automatically controlling the pressure of the pre-pressing roller 13 on the sheet material with high usage accuracy.

[0022] In this embodiment, there are two groups of limit plates 2. A connecting groove 21 is penetrated through the middle of the upper end of the limit plate 2, and the connecting groove 21 is slidably connected to the electric roller 14. Slide grooves 22 are horizontally opened on both sides of the inner wall of the bottom end of the conveying frame 11. The bottom end of the limit plate 2 is slidably connected to the slide groove 22. The inside of the slide groove 22 is horizontally connected to a bidirectional screw rod 23 through a bearing for horizontal rotation. The bidirectional screw rod 23 horizontally penetrates the bottom side of the limit plate 2 and is threadedly connected to the limit plate 2. A servo motor 24 is fixedly connected to the bottom end of one side of the conveying frame 11, and the shaft end of the servo motor 24 is fixedly connected to one end of the bidirectional screw rod 23. A placement groove 25 is penetrated through the side of the conveying frame 11 away from the circle making machine body 1, and the placement groove 25 is placed above the electric roller 14.

[0023] In this technical solution, the servo motor 24 is controlled by the corresponding controller to drive the bidirectional screw 23 to rotate. The electric roller 14 is slidably connected to the connecting groove 21 in the middle of the limit plate 2. The rotation of the bidirectional screw 23 can drive the two groups of limit plates 2 to move relative or in the opposite direction, thereby limiting the sheet material above the electric roller 14 to avoid deviation during the pre-pressing process of the sheet material and affecting the accuracy of use.

[0024] When a circle making machine with sheet material pre-pressing is used, the placement groove 25 opened on one side of the conveying frame 11 makes it convenient for the staff to place the sheet material on the inner side of the conveying frame 11 and above the electric roller 14. The servo motor 24 is controlled by the corresponding controller to work, which can drive the bidirectional screw rod 23 to rotate. The electric roller 14 is slidably connected with the connecting groove 21 in the middle of the limit plate 2. The rotation of the bidirectional screw rod 23 can drive the two groups of limit plates 2 to move relative to or in the opposite direction on the outside of the electric roller 14, so that the sheets of different sizes above the electric roller 14 can be limited, avoiding deviation during the pre-pressing process of the sheet material, which affects the use accuracy. The operation of the electro-hydraulic push rod 18 is controlled by the corresponding controller, and the pre-pressing roller 13 on the inner side of the adjusting frame 12 can be pushed downward through the connecting block 16. The sheet material inside the conveying frame 11 can be pre-pressed through the electric roller 14. The pressure of the connecting block 16 can be detected by the pressure sensor 17, and the pressure of the pre-pressing roller 13 on the sheet material can be further detected. When the pressure of the pre-pressing roller 13 on the sheet material reaches the threshold of the pressure sensor 17, the pressure sensor 17 can transmit the data to the corresponding controller, and the corresponding controller can automatically control the electro-hydraulic push rod 18 to stop working, thereby automatically controlling the pressure of the pre-pressing roller 13 on the sheet material, with high accuracy.
