Down-cutting device for steel bar trusses

Abstract

The invention provides a down-cutting device for steel bar trusses and belongs to the technical field of steel bar truss machines. The down-cutting device comprises a translation mechanism and a down-cutting mechanism; the translation mechanism comprises a supporting seat, translation rollers and a translation guide rail; translation supports are arranged at the left and right two ends of the supporting seat; the translation rollers are arranged on the outer sides of the translation supports, and the included angle of two translation rollers in each group is 90 degrees; the translation rollers can be arranged on the translation guide rail in such a manner of rolling back and forth; a lead screw is in threaded connection to a rear supporting plate; the down-cutting device comprises a left cutting tool, a right cutting tool, a fixed tool and a fixed tool holder; the middle sections of the left cutting tool and the right cutting tool are hinged to a front supporting plate; one end of a cutting cylinder is connected to the cylinder mounting base of a left tool holder, while the other end of the cutting cylinder is connected to the cylinder mounting base of a right tool holder; the cutting edge of the left cutting tool is opposite to the cutting edge of the right cutting tool; the fixed tool is mounted on the fixed tool holder; guide blocks are arranged on the two sides of the fixed tool holder. The down-cutting device can be flexibly adjusted in cutting position and improved in cutting efficiency, and is high in applicability.

Description

technical field [0001] The invention relates to the technical field of steel bar truss machines, in particular to a lower cutting device for steel bar trusses. Background technique [0002] The steel truss floor deck is a kind of unsupported pressure-type composite floor deck. The steel bar truss is finalized and processed in the background processing field. On-site construction needs to first fix the profiled plate on the steel beam with studs, and then place the steel bar truss Binding is carried out, and concrete is poured after acceptance. 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...

Problems solved by technology

At present, part of the steel truss products are cut off manually with a cutting machine. The above method has the following disadvantages: Since the steel truss products are placed on the truss forming machine, cutting is troublesome and the cutting efficiency is low.

However, it is inconvenient to adjust the front and rear positions of the cutting mechanism, resulting in the inability to flexibly adjust the cutting position
