Description

Technical Field

[0001] This utility model relates to the technical field of steel structure processing equipment, specifically to a bending device for steel structure processing. Background Technology

[0002] In steel structure fabrication, steel plates are frequently stamped into U-shaped parts. Traditional stamping equipment uses upper and lower dies for stamping, but after stamping, the U-shaped workpiece is prone to getting stuck in the lower die groove or bending head due to its shape or material elasticity, making it difficult to remove. Current technology typically uses manual hammering or simple mechanical ejection devices, but these are inefficient and can easily damage the workpiece or die, posing safety hazards.

[0023] The present invention will now be described in further detail with reference to the accompanying drawings.

[0024] Combined with appendix Figure 1 To be continued Figure 6 A bending device for steel structure processing includes a base frame 1, a mold groove 2 fixedly provided on the upper end face of the base frame 1, a support 3 fixedly provided on the rear side of the upper end face of the base frame 1, an electric push rod 4 fixedly provided on the support 3, a bending pressure head 5 adapted to the mold groove 2 fixedly provided on the piston end of the electric push rod 4, an electromagnet 6 for adsorbing the bent workpiece and preventing it from getting stuck on the bending pressure head 5 is embedded and fixedly provided inside the bottom surface of the mold groove 2; an ejection mechanism 7 for ejecting the workpiece from the mold groove 2 is provided on the inner side of the support 3; upright plates 8 are fixedly provided on the left and right sides of the upper end of the mold groove 2, and a platform 9 for placing steel plates is formed between the inner side of the upright plates 8 and the upper end of the mold groove 2; and a stop block 10 with adjustable horizontal spacing is provided on the inner side of both upright plates 8.

[0025] The ejection mechanism 7 includes an ejector block 71 and an electric push rod 72. The electric push rod 72 is fixedly mounted on the outside of the bracket 3 and is used to drive the ejector block 71 to reciprocate. The ejector block 71 extends into the mold groove 2. The ejector block 71 has a triangular cross-section and its three edges are close to the inner surface and bottom surface of the mold groove 2, respectively. A controller 13 is fixedly mounted on the base frame 1. The electric push rod 4, the electromagnet 6, and the electric push rod 72 are all electrically connected to the controller 13. They are used to delay the power cut-off of the strong electromagnet 3 after the bending pressure head 5 is raised and to trigger the ejection mechanism 7 to operate.

[0026] An adjusting bolt 11 is threadedly connected to the upright plate 8. The end of the adjusting bolt 11 is rotatably connected to the side of the stop block 10. A guide rod 12 is fixedly provided on the outside of the stop block 10. The guide rod 12 passes through the upright plate 8 and slides with the upright plate 8. The cross section of the stop block 10 is a right triangle and the inclined surfaces of the two stop blocks 10 are arranged opposite each other.

[0027] The working process of this utility model is as follows:

[0028] 1. Based on the width of the steel plate to be processed, rotate the adjusting bolt 11 to drive the stop block 10 to move horizontally along the guide rod 12 until the distance between the two stop blocks 10 matches the width of the steel plate and the steel plate is placed in the center of the platform 9; at this time, the right-angled triangular inclined surfaces of the stop block 10 face each other, forming a flared structure, which facilitates the placement of the steel plate.

[0029] 2. Place the steel plate 14 to be bent onto the platform 9 formed by the inner side of the upright plate 8 and the upper end of the mold groove 2. Guided by the flared structure of the stop block 10, the steel plate is positioned between the two stop blocks 10, and the center of the steel plate is aligned with the center of the mold groove 2 and the bending pressure head 5, thus completing the workpiece positioning.

[0030] 3. The controller 13 sends a command (the controller is a PLC controller) to start the electric push rod 4. The piston end of the electric push rod 4 pushes the bending head 5 downward. The bending head 5 cooperates with the mold groove 2 to punch and bend the steel plate on the platform 9, so that the steel plate gradually forms a U-shaped structure. During the punching and bending process, the controller 13 controls the electromagnet 6 embedded in the bottom surface of the mold groove 2 to be energized. The electromagnet 6 generates magnetic force to attract the bent workpiece, preventing the workpiece from moving synchronously with the bending head 5 due to material elasticity or shape factors.

[0031] 4. After the steel plate is bent into a U-shaped workpiece and the processing is completed, the controller 13 sends a command to cause the piston end of the electric push rod 4 to drive the bending pressure head 5 to return upward and leave the area of ​​the mold groove 2. After the bending pressure head 5 rises, the controller 13 controls the electromagnet 6 to de-energize, and at the same time triggers the ejection mechanism 7 to act: the electric push rod 72 is activated, and the electric push rod 72 drives the ejector block 71 to move into the mold groove 2. The ejector block 71 has a triangular cross-section and its three edges are close to the inner side and bottom surface of the mold groove 2, respectively. After it extends into the mold groove 2, according to the structural characteristics of the U-shaped workpiece, it forms up to three support points from the bottom edge and two sides of the workpiece end (the figure shows a single support point), which ejects the U-shaped workpiece from the mold groove 2. After the workpiece is ejected from the mold groove 2, the electric push rod 72 drives the ejector block 71 to return to its original position, and the operator removes the ejected U-shaped workpiece, completing one bending process.

[0032] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
