Description

Technical Field

[0001] This utility model belongs to the field of steel plate processing technology, and specifically relates to a bending device for steel plate processing. Background Technology

[0002] Bending devices for steel plate processing are specialized mechanical devices used in the field of metal sheet processing. They apply external force to induce a predetermined plastic deformation in the steel plate, thereby obtaining a specific bending angle and bending radius. They are key equipment for the cold forming of steel plates and are widely used in industries such as machinery manufacturing and steel structures. Their core function is to transform flat steel plates into components with three-dimensional geometric shapes.

[0003] Before bending a steel plate, it needs to extend the steel plate beyond the predetermined size of the workbench. Existing bending devices are not convenient for accurately measuring the size of the steel plate that needs to be extended for bending. Moreover, after the steel plate extends beyond the required bending size, it is often necessary to manually press down on the steel plate. Such manual pressing may cause the steel plate to shift beyond the bending size, making it difficult to bend a steel plate with accurate dimensions. Utility Model Content

[0033] Brief description of the operation: Rotate the hand ring 1605, which drives the threaded sleeve 1603 to rotate. The threaded sleeve 1603 drives the threaded rod 1601 to move. Under the cooperation of the slide rail 12 and the slider 13, the pressing plate 1401 and the roller 1403 move synchronously. The adjusting spring 1602 and the spring rod 20 are in a compressed state, which facilitates the bending of the steel plate to different sizes within a certain range. Extend the steel plate out of the worktable to the pressing plate 1401, and start the hydraulic cylinder 4. The telescopic end of the hydraulic cylinder 4 drives the support plate 5, the bending column 7 and the wedge block 1402 to move down synchronously. At the same time, the pressing plate 11 will also move down under the action of the hydraulic cylinder 4. First, the pressing plate 11 will contact the steel plate. After being pressed, the support plate 5 continues to move downwards, the cylindrical track 101 and the compression spring 10 are in a compressed state, the wedge block 1402 will contact the roller 1403 and exert force on the roller 1403. At this time, under the cooperation of the slide rail 12 and the slider 13, the roller 1403, the pressing plate 1401, the threaded rod 1601, the threaded sleeve 1603, the hand ring 1605, etc. will move to the right, so that the pressing plate 1401 separates from the steel plate. The adjusting spring 1602 and the spring rod 20 continue to be in a compressed state. Finally, the bending column 7 contacts the steel plate and rotates. At the same time, the slide rod 503 will rotate synchronously in the slide groove 502. During the rotation of the bending column 7, the steel plate will be bent. After bending is completed, the extension end of the hydraulic cylinder 4 retracts, causing the support plate 5, wedge block 1402, bending column 7, and pressing plate 11 to move upward. The bending column 7 is reset under the action of the torsion spring 9, and the pressing plate 1401, roller 1403, threaded rod 1601, threaded sleeve 1603, and hand ring 1605 are reset under the action of the adjusting spring 1602 and spring rod 20, preparing for the next bending.
