Profile seamless bending mold and seamless bending method

Abstract

The invention belongs to the field of section bar bending equipment and provides a section bar seamless bending die. A section bar comprises a side board and a rib plate extending from one side edge of the side board and arranged perpendicular to the side edge. The die comprises a die holder, a female die installed on the die holder, a male die installed on the die holder and matched with the female die to bend the section bar and a first driving mechanism driving the male die to move to the female die to abut against and bend the section bar; the die further comprises a pressing board installed on the female die and used for abutting against the rib plate of the section bar and a second driving mechanism driving the pressing board to abut against the rib plate. The pressing board is arranged to abut against the rib plate, so that when the section bar is bent, plastic deformation is conducted on the rib plate of the section bar through the match of the male die and the pressing board, and stacking of the rib plate is prevented. Cutting does not need to be conducted on the rib plate of the section bar, so that the good strength of the rib plate is guaranteed. The invention further discloses a method for seamless bending through the section bar seamless bending die. The method is easier and more convenient to conduct and capable of guaranteeing the good strength of the rib plate.

Description

technical field [0001] The invention belongs to the field of profile bending equipment, and in particular relates to a profile seamless bending mold and a method for using the profile seamless bending mold to perform profile seamless bending. Background technique [0002] With the development trend of ultra-thin and ultra-narrow LCD TVs, people pay more and more attention to the appearance and workmanship of the products. Due to its advantages of high strength, light weight, and beautiful appearance after surface treatment, aluminum profiles are increasingly used as exterior structural parts such as TV front frames and middle frames. In the production of structural parts such as TV frame and middle frame, F-shaped, L-shaped and other aluminum profiles with larger-sized appearance ribs are mostly used. When processing these profiles into structural parts such as face frames and middle frames, the prior art generally adopts the following two methods: (1) Using profile splicin...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a seamless bending mold for profiles, which aims to solve the problem that in the current seamless bending method, it is necessary to make incisions on the rib plate at the bending position of the profile, resulting in the corresponding bending angle after bending. There are splicing gaps and step differences on the rib plate; if no cut is made on the rib plate, the rib plate at the bend will be stacked during bending
