For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0036] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0037] Reference Figure 1-5 The present embodiment provides a thin plate bending device, whose structure includes: an operating table 1, a support frame 2, a telescopic tool 3, a transporter 4, a baffle 1 5 and a baffle 2 6. The support frame 2, the baffle 1 5 and the baffle 2 6 are all located on the operating table 1. The operating table 1 is provided with a knife groove 1-1, and the support frame 2 is provided with a transporter 4 and a telescopic tool 3 corresponding to the position of the knife groove 1-1. The baffle 1 5 and the baffle 2 6 are respectively located on both sides of the knife groove 1-1, and the transporter 4 and the baffle 1 5 are located on the same side of the knife groove 1-1, wherein: the operating table 1 is used to place the thin plate, the baffle 1 5 is used to limit the end of the thin plate, the baffle 2 6 is used to limit the side of the thin plate, the telescopic tool 3 is used to extend into the knife groove 1-1 to bend the thin plate, and the transporter 4 is used to transport the bent finished product.

[0038] The above-mentioned device can continuously bend the thin plate to form a cylinder with a side opening. The transporter 4 moves the bent product to the welding station (the telescopic tool 3 detaches from the open side to the outside of the cylinder), and welds and fixes the open side to form the required large-sized square pipeline. There is no need to split the thin plate throughout the process, which reduces the number of assembly and welding processes, reduces working time, manpower and welding material costs, and the formed square steel pipe has only one neat weld. Compared with the finished product of four-plate welding, its external aesthetics is greatly improved, and the probability of leakage of the medium inside the pipeline is effectively reduced.

[0039] The support frame 2 includes a vertical support 2-1, a diagonal support 2-2, a cross beam 2-3 and a transfer rail 2-4. The vertical support 2-1 and the diagonal support 2-2 are both arranged on the operating table 1. The vertical support 2-1 is located on both sides of the knife groove 1-1, and the top is connected to and supports the cross beam 2-3 on which the telescopic tool 3 is installed; the diagonal support 2-2 is located on one side of the knife groove 1-1, and its top is inclined in the direction away from the vertical support 2-1, until its projection in the horizontal direction exceeds the operating table 1, so as to connect and support the other cross beam 2-3; the transfer rail 2-4 is installed at the bottom of the two cross beams 2-3 and is supported by the connection thereof. One end of the transfer rail 2-4 is close to the knife groove 1-1, and the other end is away from the knife groove 1-1 and extends to the outside of the operating table 1, so as to facilitate the transporter 4 installed on the transfer rail 2-4 to move to the welding process outside the operating table 1.

[0040] The inclination of the above-mentioned diagonal brace 2-2, the length of the transfer rail 2-4, etc. are configured according to actual use requirements and are not specifically limited here; the material selection of the transporter 4 can be configured according to actual use requirements and can meet the needs of reciprocating movement and lifting of thin plates on the transfer rail 2-4, for example, by using an electric hoist 4-1 and a wire rope 4-2.

[0041] The two ends of the cross beam 2-3 supported by the vertical support 2-1 extend out of the operating table 1, and the telescopic tool 3 is installed at the position where it extends out of the operating table 1 to avoid unplanned collision or obstruction with the thin plate on the operating table 1. At the same time, in addition to supporting the cross beam 2-3, the vertical support 2-1 is located on both sides of the knife groove 1-1, that is, on both sides of the telescopic tool 3, and can also play an auxiliary limiting role for the telescopic tool 3, limiting the horizontal shaking of the telescopic tool 3 due to excessive elongation, improving the accuracy of its lowering position and angle, and improving the manufacturing accuracy of the square pipe.

[0042] The width of the thin plate is determined by the length dimension of the square steel tube, the total length of the thin plate is determined by the cross-sectional circumference of the square steel tube, and the bending point of the thin plate is determined by the cross-sectional side length of the square steel tube. Therefore, in order to meet the production requirements of square steel tubes of different sizes, in this embodiment, a slot 1-2 perpendicular to the knife slot 1-1 is provided on the operating table 1, a shift component 8 is provided in the slot 1-2, and a baffle 5 is provided on the shift component 8, which can be close to or away from the knife slot 1-1 to meet the requirements of different bending points of the thin plates; the baffle 2 6 is configured to include a fixed plate 6-1 and a movable plate 6-2, which are correspondingly arranged, the fixed plate 6-1 is fixed on the operating table 1, and a slot 2 1-3 parallel to the knife slot 1-1 is provided on the operating table 1, a shift component 2 9 is provided in the slot 2 1-3, and the movable plate 6-2 is provided on the shift component 2 9, which can be close to or away from the fixed plate 6-1 to meet the requirements of limiting the width direction of different thin plates.

[0043] During construction, the width of the thin plate is determined according to the length of the square steel tube, and the total length of the thin plate is determined according to the cross-sectional circumference of the square steel tube (a slight redundant length can be pre-added), and the selected thin plate is placed on the operating table 1; the spacing between the baffle 5 and the knife groove 1-1 is determined according to the cross-sectional side length of the square steel tube, and the baffle 5 is moved into place by the shifting component 8; one end of the thin plate along the length direction is pressed against the baffle 5, and one side along the width direction is pressed against the fixed plate 6-1, and the position of the movable plate 6-2 is adjusted by the shifting component 9 until the movable plate 6-2 just presses against the other side of the thin plate along the width direction, completing the alignment of the steel plate before bending to ensure the bending accuracy.

[0044] In order to prevent the baffle plate 5 and the moving plate 6-2 from being squeezed and moved, the shifting assembly 8 and the shifting assembly 9 are both equipped with self-locking structural accessories, for example: the shifting assembly 8 is configured as a screw rod 8-1 and a slider 8-2, a rotating head 8-3 is arranged at the end of the screw rod 8-1 extending out of the operating table 1, the slider 8-2 is threadedly connected to the screw rod 8-1, and the outer wall is in contact with the slot 1-2, the shifting assembly is configured as a screw rod 9-1 and a slider 9-2, a rotating head 9-3 is arranged at the end of the screw rod 9-1 extending out of the operating table 1, the slider 9-2 is threadedly connected to the screw rod 9-1 , and the outer wall is in contact with the slot 1-3; the baffle 5 and the movable plate 6-2 are respectively located at the top of the slider 8-2 and the top of the slider 9-2, and the screw 8-1 and the screw 9-1 are driven to rotate by the rotating head 8-3 and the rotating head 9-3. Restricted by the inner walls of the slot 1-2 and the slot 1-3, the slider 8-2 and the slider 9-2 can only move but not rotate, thereby realizing the position adjustment of the baffle 5 and the movable plate 6-2. Due to the self-locking of the threaded connection, simply squeezing the baffle 5 or the movable plate 6-2 cannot change their positions, thereby ensuring accurate limit positioning.

[0045] In order to improve the convenience of use, the present embodiment further provides a ruler 7 on the operating table 1. The ruler 7 is located outside the slot 1-2 and is consistent with its extending direction, so as to mark the distance between the baffle 5 and the knife groove 1-1.

[0046] When manufacturing square steel pipes, the bending angle of the thin plate is 90°, so in this embodiment, the telescopic tool 3 is configured to include a hydraulic cylinder 3-1 and a bending knife 3-2. The telescopic rod of the hydraulic cylinder 3-1 is connected to the bending knife 3-2. The bending knife 3-2 is in the shape of a long rod, and the lowest point of its longitudinal section is a right angle. The knife groove 1-1 is adapted to its shape. In order to simplify the manufacturing process, the bending knife 3-2 can be set to a triangular prism shape.

[0047] The method for using the device comprises the steps of:

[0048] (1) Determine the length, width and bending point of the thin plate according to the dimensions of the square steel tube in all directions;

[0049] (2) placing the thin plate on the operating table 1, and using baffle plate 1 5 and baffle plate 2 6 to align and limit the plate before bending;

[0050] (3) Start the telescopic tool 3 to press the thin plate into the knife groove 1-1 to form a first bending portion; push the thin plate to sequentially form a second bending portion and a third bending portion;

[0051] (4) Start the transporter 4 to transfer the bent finished product to the welding station.

[0052] Compared with the prior art, the beneficial effect of the utility model is that in the production process of large-size square pipes, there is no need for thin plate segmentation throughout the entire process, which reduces the number of assembly and welding processes, reduces working time, manpower and welding material consumption, and the formed square steel pipe has only one neat weld. Compared with the finished product of four-plate welding, its external aesthetics is greatly improved, and the probability of leakage of the medium inside the pipeline is effectively reduced.

[0053] The above are preferred implementations of the present utility model. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present utility model. These improvements and modifications should also be regarded as the protection scope of the present utility model.
