Description

Technical Field

[0001] The utility model relates to the technical field of container manufacturing, and specifically to a device for correcting the curvature of a folding box side beam wing plate. Background Art

[0002] A folding box is a special container. When the empty box is returned, multiple folding boxes can be stacked and interlocked together, thereby reducing the space occupied during return transportation. The folding box generally includes a base frame and two end walls located at both ends of the base frame. A fixed hinge is connected to each of the four end corners of the base frame, and movable hinges are connected to both sides of each end wall. The movable hinges on both sides of the end wall are respectively connected to two fixed hinges at one end of the base frame. The movable hinges are pivotally connected to the fixed hinges through hinge pins. In this way, the end wall can rotate relative to the base frame and can be folded and placed horizontally on the base frame.

[0003] The structure of the folding box requires the use of I-beams, such as the side beams of the folding box, etc., and the I-beam is composed of two upper and lower wing panels and a middle waist panel. The wing panels need to be cut into strips by laser or flame cutting during the processing. The stripped wing panels are bent 30mm-45mm due to the cutting stress, which cannot meet the subsequent I-beam positioning requirements. Therefore, the strip wing panels need to be corrected. When pressure is applied to the side panels of the strip wing panels for correction, the strip wing panels are prone to warping, which will cause safety accidents. Utility Model Content

[0031] See also Figure 1 and Figure 2 , an embodiment of the utility model provides a device for correcting the curvature of a folding box side beam wing plate, comprising: a correction frame 10, a plurality of movable pressing devices 20 and a plurality of correction devices 30;

[0032] The correction frame 10 is provided with a guide rail 11 and a plurality of wing plate limiting frames 12. The plurality of wing plate limiting frames 12 are sequentially arranged along the guide direction of the guide rail 11, and the wing plates are placed on the wing plate limiting frames 12.

After the wing plate is placed on the wing plate limit frame 12, the pressing assembly 22 drives the pressure roller 23 to descend, and the pressure roller 23 is pressed on the top of the wing plate. The walking frame 21 can move along the guide rail 11 to adjust the position of the pressure roller 23 so that the pressure roller 23 can roll along the wing plate to prevent the wing plate from tilting during correction. The translation drive assembly 31 drives the correction plate 32 to press the wing plate toward the limit frame, thereby straightening the wing plate.

[0033] In some optional embodiments, a support portion 121 and a limit groove 122 are provided on the wing plate limit frame 12. The limit groove 122 is provided on the side of the support portion 121 away from the correction plate 32. The workpiece 50 is placed on the support portion 121, and one side of the workpiece 50 extends into the limit groove 122. The limit groove 122 limits the position of the workpiece 50 to prevent the workpiece 50 from shifting during the correction process. The translation drive assembly 31 drives the correction plate 32 to press the wing plate into the limit groove 122 on the limit frame.

[0034] In order to facilitate the installation of the pressure roller 23 , in some optional embodiments, the mobile pressing device 20 further includes a lifting seat 24 , the pressing assembly 22 is drivingly connected to the lifting seat 24 , and the pressure roller 23 is rotatably disposed on the lifting seat 24 .
