Embodiment Construction

[0048] like Figure 1 to Figure 8 As shown, the present invention provides a method for bending a section steel, which is carried out by a top-pull section steel bending machine; the section steel 8 (I-beam or H-beam) includes a front end plate 10, a rear end plate 11 and a front end plate 11, which are oppositely arranged. 10 and the middle plate 12 between the rear end plate 11; the top-pull type steel bending machine of the present invention includes a section steel limit conveying mechanism, a section steel bidirectional synchronous bending device and a bending degree measuring device;

[0049] The section steel limit conveying mechanism includes a workbench 1, the right end of the workbench 1 is the loading end 2 of the section steel 8, and the left end of the workbench 1 is the unloading end 3 of the section steel 8;

[0050] The left end of the worktable 1 is provided with a left driving device 31 for driving the profiled steel 8, and the right end of the worktable 1 is...

Abstract

The invention discloses a profile steel bending machining method. The profile steel bending machining method is performed according to the following steps that S1, a preparation step is performed, wherein firstly, a handle is rotated to guaranteed that the distance between each pressing roller and a corresponding supporting roller is larger than the height of a front end plate and a rear end plateof profile steel; S2, an initial feeding step is performed, wherein the profile steel sequentially penetrates through each correcting and limiting device and a profile steel bidirectional synchronousbending device from left to right; S3, a bending machining step is performed, wherein a pull cylinder hydraulic cylinder and an abutting cylinder hydraulic cylinder synchronously act, the profile steel is bent due to the fact that the front end plate and the rear end plate of the profile steel are synchronously stressed, a motor of a left driving device and a motor of a right driving device are synchronously started, a driving wheel drives the profile steel to move leftwards through friction force, and the bent profile steel is leftwards sent out of a working table. According to the profile steel bending machining method, the procedure arrangement is compact and efficient, the conveying function and the limiting function of a profile steel limiting and conveying mechanism on the profile steel can be fully utilized, so that excessive local deformation of the profile steel is prevented while the profile steel is bent, and then the quality of the profile steel is ensured.

Description

technical field [0001] The invention relates to the technology of cold-bending of section steel, in particular to the equipment of cold-bending of section steel. Background technique [0002] The top-pull type section steel bending machine of the present invention is mainly used for bending section steels such as I-beam and H-beam. The section steel includes a front end plate, a rear end plate and a middle plate connected between the front end plate and the rear end plate. [0003] The existing section steel bending machine is composed of main motor, cycloidal pinwheel reducer, roller, oil pump motor, gear oil pump, relief valve, electromagnetic reversing valve, working oil cylinder, top wheel and oil tank. On the bending machine, after the section steel contacts the roller driven by the cycloidal pinwheel reducer, the motor oil pump unit is started, and the high-pressure oil output by the electric oil pump enters the electro-hydraulic valve through the relief valve (the re...
