Description

Technical Field

[0001] The utility model relates to the technical field of steel structure processing, in particular to a bending machine used for manufacturing steel structures. Background Art

[0002] Steel structure is a building structure composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates. It has the advantages of high strength, light weight, good overall rigidity and strong resistance to deformation. Therefore, it is used to build large-span, super-high and super-heavy buildings. The steel plates in the steel structure need to be bent and processed by a bending machine before they can be used.

[0003] For example, Chinese patent announcement No. CN216027263U discloses a bending machine for steel structure manufacturing. When in use, the steel structure is placed above the operating table, and the extrusion block is opened to extrude the steel structure. The extruded steel structure will be stuck on the inner side of the bending groove. It is only necessary to open the hydraulic rod on the right end face of the vertical plate, and the hydraulic rod drives the fixed plate to move to the right, and the fixed plate drives the push rod to move to the right, so that the steel structure stuck on the inner side of the bending groove is pushed outward. At the same time, a rubber block is provided on the top of the push rod, which can reduce the impact force of the push rod on the steel structure, and prevent the top of the steel structure after the bending from having two round holes left by the push rod impacting the steel structure. When the bent steel structure moves out of the inner side of the bending groove, the vertical motor is turned on, and the vertical motor drives the handle to rotate. The rotating shaft at the top of the handle drives the moving block to move up and down with the rotation of the handle, and the sliding rod inside the moving block drives the push block to push the bent steel structure upward, so that the operator can put his hand into the bottom end of the steel structure and lift it up, which increases the convenience of the operator to a certain extent and is very practical.

[0004] However, the bending machine for steel structure manufacturing in the above application can only bend steel plate structures and can only process steel structures of specific angles, and has a limited scope of application. Therefore, there are certain limitations.

[0005] For this reason, we urgently need to provide a bending machine for steel structure production. Utility Model Content

Then the electromagnetic ring is energized to generate a magnetic field. The magnetorheological fluid inside the rubber airbag is transformed from low-viscosity Newtonian fluid characteristics to high-viscosity, low-fluidity Bingham body characteristics as the magnetic field changes, thereby supporting and fixing the inner wall of the steel structure to adapt to steel structures of different sizes, thereby improving the applicability of the device.
