Forward and reverse combined bending device for granary plates

Abstract

The invention discloses a forward and reverse combined bending device for granary plates. The forward and reverse combined bending device comprises a rack, a downward bending mechanism, two upward bending mechanisms and pressing mechanisms. The rack is provided with a table top used for containing granary plates. The pressing mechanisms are arranged on the upper sides of the two ends of the table top correspondingly, and the ends of the granary plates are pressed through descending of the pressing mechanisms. The upward folding mechanisms are arranged on the lower sides of the two ends of the table top correspondingly, and the ends, extending out of the table top, of the granary plates are folded upwards through upward folding of the upward folding mechanisms. The downward folding mechanism is arranged on the upper side of the position, between the two upward folding mechanisms, of the table top. A cross section is arranged at the position, below the downward folding mechanism, of the table top, and the ends, extending out of the cross section, of the granary plates are downwards folded through downward folding of the downward folding mechanism. According to the device, the two ends of the granary plates can be bent forwards and reversely through the downward bending mechanism and the upward bending mechanisms correspondingly, the production efficiency is high, the forming precision is good, large-scale and batch bending can be conducted, and the actual profile production requirement is effectively met.

Description

technical field [0001] The invention relates to the technical field of profile processing equipment, in particular to a forward and reverse combined bending device for granary boards. Background technique [0002] Sectional steel is a bar-shaped steel with a certain cross-sectional shape and size. According to the quality of steel smelting, section steel is divided into ordinary section steel and high-quality section steel. Ordinary section steel is divided into large section steel, medium section steel and small section steel according to the current metal product catalogue. Ordinary section steel can be divided into I-beam, channel steel, angle steel, round steel and so on according to its cross-sectional shape. In actual production and application, shaped steel is often used as the granary plate. In order to better splice the adjacent granary plates together, it is necessary to perform forward and reverse bending at both ends of the granary plate, so that the head and t...

AI Technical Summary

Problems solved by technology

At present, the processing method of forward and reverse bending at both ends of the granary board is manually carried out, which has low production efficiency and poor forming accuracy, and it is difficult to meet the actual production needs of profiles.
