Automatic sheet metal bending production line

Abstract

The invention discloses an automatic sheet metal bending production line. The production line comprises a bending machine base, a bending die base and a material pressing mechanism. A conveying support arm is installed on the upper side of one end of the bending machine base, the upper side of the conveying support arm is provided with a feeding roller through a conveying rotary shaft, the two sides of the upper end of the conveying support arm are provided with a material pressing mechanism, and the bending die base is rotationally installed on the upper side of one end of the bending machinebase. The lower side of the bending die base is in transmission connection with a motor through a die changing rotating shaft, a square bending groove and a trapezoid bending groove are formed in thetwo ends of the upper side of the bending die base respectively, a bending support is arranged in the middle of the upper side of the bending die base, a first hydraulic cylinder and a second hydraulic cylinder are installed on the two sides of the upper end of the bending support, and the lower side of the first hydraulic cylinder is provided with a square bent head through a first telescopic rod. According to the automatic sheet metal bending production line, the bending effect of different shapes can be completed by switching different stations, and the function of automatic feeding can berealized.

Description

technical field [0001] The invention relates to the technical field of sheet metal processing, in particular to an automatic production line for sheet metal bending. Background technique [0002] Sheet metal, a processing technology, sheet metal has not yet had a relatively complete definition. According to a definition in a foreign professional journal, it can be defined as: sheet metal is a comprehensive cold processing process for metal sheets (usually below 6mm), including shearing, punching / cutting / compositing, folding, riveting, splicing, Forming (such as car body), etc. Its remarkable feature is that the thickness of the same part is consistent. Sheet metal processing is called sheet metal processing. Specifically, for example, using plates to make chimneys, iron barrels, fuel tanks, ventilation pipes, elbows, round places, funnel shapes, etc. The main processes are cutting, bending buckle, bending forming, welding, riveting, etc. Sheet metal parts are thin-plate ...

AI Technical Summary

Problems solved by technology

[0003] The existing technology has the following disadvantages: the traditional sheet metal bending technology uses manual tapping to beat the bending part, which is time-consuming and laborious, and the existing sheet metal bending equipment only has a single bending station, which is not convenient for continuous bending. Bending processing of different traces, the bending efficiency of sheet metal parts is low
