Description

Technical Field

[0001] The utility model relates to the technical field of cold-bent profile processing equipment, in particular to a cold-bent profile processing and cutting device. Background Art

[0002] Cold-formed steel, also known as steel cold-bent profiles or cold-formed profiles, is a type of profile with various complex cross-sections that is made from hot-rolled or cold-rolled strip steel as a blank through pressure processing at room temperature. This type of profile is widely used in production departments such as construction, railway vehicles, automobiles and ships due to its economical and reasonable cross-section and a wide variety of varieties. It is used to make structural parts and auxiliary parts. In terms of production technology, cold-formed steel can be made of ordinary carbon structural steel, high-quality carbon structural steel, low-alloy structural steel and other materials through cold bending. In recent years, with the advancement of technology, the production process of cold-formed steel has also been continuously developing, such as three-dimensional cold bending technology, branch forming technology and local heating roll bending forming technology. The application of these technologies has made cold-formed steel more and more widely used in fields such as automobiles, construction and infrastructure.

[0003] The utility model with application number 202020998072.0 discloses an automatic cutting device for cold-bent profiles. A conveyor belt is arranged at the center of a cutting platform, and the conveyor belt is composed of a plurality of conveyor rollers. The conveyor belt is aligned with the discharge port of a cold-bending device in the early stage, and the cold-bent profiles can be directly transported to the conveyor belt along the discharge port. Baffles are arranged on both sides of the conveyor belt for limiting. Therefore, the device is convenient for feeding, labor-saving, and can effectively save labor. A filter barrel is arranged under the notch, and at least two layers of filter screens are arranged in the filter barrel to filter the metal debris generated by cutting. When cleaning, the filter screen is taken out from the slag cleaning port, rinsed and cleaned, and reused. This method has a flexible structure, simple filter screen replacement, and can select a filter screen with a suitable aperture according to the size of the metal debris. There is no need to use a drive motor, which saves energy consumption and costs.

[0004] However, when cutting in the above-mentioned automatic cold-bent profile cutting device, a large gap is left between the baffle and the cold-bent profile, and the cold-bent profile cannot be effectively limited and clamped during cutting, which makes the cold-bent profile easily displaced during cutting. Since the cold-bent profiles in the above-mentioned automatic cold-bent cutting device are mostly profiles with various complex cross-sections, they are easily displaced during cutting when being transported and moved on conveyor rollers, which affects the cutting effect of the cold-bent profile. Therefore, the utility model proposes a cold-bent profile processing and cutting device to solve the problems existing in the prior art. Utility Model Content
