Embodiment Construction

[0014] Referring to the accompanying drawings, take the processing of Q235-28# I-beam curved rail as an example to make a specific explanation: First, press a bending mold 2 and a fixed pulley 3 on the workbench 1 of the sheet metal processing factory respectively, and use bolts, The nut is fixed; the bending mold 2 determines the bending arc radius and arc length of the template according to the needs of the curved shape of the design, the extension of the template is close to the end face of the workbench 1, and the distance between the fixed pulley 3 and the extension of the template of the bending mold 2 greater than the length of the workpiece 5 after bending. Then, after the workpiece is blanked according to requirements, a device 4 for connecting the traction rope is welded at one end of the workpiece 5. The device 4 for connecting the traction rope is a pull pile, and the pull rope 6 is sleeved on the pull pile ; The other end of the workpiece 5 is press-fitted on the ...

Abstract

A technology for bending the large steel section includes such steps as fixing the bending die and fixed polley onto bench, welding a drawing cable jointer to one end of workpiece, connecting drawing cable to it, pressing the another end of said workpiece on the extended part of the template on bending die, passing the drawing cable through said fixed pulley, connecting it to drawing unit, turning on the drawing unit for bending the workpiece, and fixating its shape.

Description

technical field [0001] The invention relates to the field of sheet metal processing, in particular to a simple processing method for bending large section steel without special equipment. Background technique [0002] At present, the bending and forming of large-scale steel, especially curved members such as I-beams and channel steels, is generally made by special special pressure equipment and various rolling, pressing, stretching, and forming orthopedic equipment. These equipments are huge. And there are many types, and some equipment needs to be supplemented by large special molds. The purchase of these equipment requires a lot of investment. Therefore, except for professional manufacturers and special industries, ordinary enterprises do not have these production conditions. When such curved components need to be processed, they have to use outsourcing processing, which will increase the transportation cost, and sometimes the construction period will be affected due to ro...
