Steel bar clamping mechanism on steel bar truss forming machine

Abstract

The invention discloses a steel bar clamping mechanism on a steel bar truss forming machine. The steel bar clamping mechanism comprises a mounting base (1), wherein one lateral surface of the mounting base (1) is provided with a first driving arm (2), a first driven arm (3), a chuck fixed base (4), a second driven arm (5) and a second driving arm (6) sequentially from left to right; a first chuck(7) is formed between the upper end of the first driving arm (2) and the upper end of the first driven arm (3); a second chuck (8) is formed between the upper end of the first driven arm (3) and the upper end of the chuck fixed base (4); a third chuck (9) is formed between the upper end of the chuck fixed base (4) and the upper end of the second driven arm (5); a fourth chuck (10) is formed between the upper end of the second driven arm (5) and the upper end of the second driving arm (6); and the four chucks can clamp steel bars simultaneously under the driving of a driving device, namely the steel bar clamping mechanism can clamp the four steel bars simultaneously. The steel bar clamping mechanism belongs to the technical field of clamping mechanisms.

Description

technical field [0001] The invention relates to a clamping mechanism, in particular to a steel bar clamping mechanism on a steel bar truss forming machine. Background technique [0002] At present, in the construction of buildings, railways, bridges and other industries, in order to improve the bonding strength of concrete, steel bars are usually welded into steel bar trusses of different cross-sectional shapes and embedded in concrete. The section of the steel truss is generally triangular. The triangular truss includes an upper hanging bar and two lower hanging bars. The upper hanging bar and the two lower hanging bars are welded together by a corrugated steel bar bent into a wave shape. The upper hanging bar and the two corrugated bars The three wave crests are welded together, and the two sides of the middle waist of the two waves are welded together with the two lower string bars respectively. During product forming, the two hanging bars and the two steel bars to be b...

AI Technical Summary

Problems solved by technology

[0003] There are four steel bar clamping mechanisms on the existing truss forming machine. The clamping mechanism is composed of a clamping part with a jaw and an oil cylinder that controls the opening and closing of the jaw. One clamping mechanism can only clamp one steel bar at a time. , so the steel bar clamping mechanism used on the existing truss forming machine has defects such as large total installation space, high manufacturing cost, and sparse connection between each other.
