Composite heat-preservation system steel bar truss welding forming production line and truss production method

Abstract

The invention belongs to the technical field of wire mesh machining device, and discloses a composite heat-preservation system steel bar truss welding forming production line and a truss production method. The composite heat-preservation system steel bar truss welding forming production line is mainly technically characterized in that a straightening mechanism, a welding mechanism, a net pull mechanism, a net cutting mechanism, a net piece sending mechanism, a bending mechanism and a discharging mechanism are included; the welding mechanism comprises one or more pairs of horizontal wire positioning mechanisms, each horizontal wire positioning mechanism comprises a fixing base and a fixing bracket, a spring steel sheet is arranged on the upper portion of each fixing bracket, a fixed ruler head is arranged at the front end of each spring steel sheet, a transverse wire penetrating hole is formed in each fixed ruler head, a wire outlet is formed in the front end of each wire penetrating hole, and a magnetic block is arranged at the rear end of each wire penetrating hole; and the bending mechanism comprises an upper bending cutter and a lower bending cutter corresponding to the upper bending cutter, a wire-jacking clamping groove with the section being semicircular is formed in the upper portion of the lower bending cutter, and a net piece conveying rack is located between the upperbending cutter and the lower bending cutter. When a net piece is pulled forwards, a transverse bar is pulled out from the wire outlet, the net piece is uplifted, abrasion of a lower electrode is avoided, the bent net piece is hooked by a discharging hook, and discharging is facilitated.

Description

technical field [0001] The invention belongs to the technical field of wire mesh processing devices, and in particular relates to a method for producing the truss in a welding and forming production line of a steel bar truss of a composite thermal insulation system. Background technique [0002] In construction and other wire mesh applications, especially in composite thermal insulation systems, triangular truss mesh is used in many places. At present, the main production method is to weld the large mesh first, then cut and bend it by a shearing machine, and move the cut mesh to the bending machine. During the bending process, there are the following defects: First, when the mesh moves The labor intensity is high and the production efficiency is low; secondly, due to the poor positioning of the mesh, the quality of the produced triangular truss is poor, and it is easy to cause uneven thickness of the wall during use. Contents of the invention [0003] The first technical ...
