An automatic forming method for hollow welded mesh

Abstract

The invention discloses an automatic forming method of a hollow welding net. The automatic forming method comprises the following steps that when holes are not needed, only a weft straightening and cutting device at one end is opened to produce wefts, meanwhile warp wire rods enter a warp conveying device after being straightened by a warp straightening mechanism, and each warp runs at a normal step distance and is welded in a whole row at a main machine; when a position which needs to be opened is met, step-by-step warps at the opening stop stepping at the warp conveying device, and are positioned and cut off at the corresponding position, and the rest warps continuously step, when stepping to a welding part of the main machine, the weft straightening and cutting devices at the two ends of the main machine work at the same time and respectively convey step-by-step wefts of corresponding sizes from the left direction and the right direction according to the position of the hole, and with the progress of stepping, the holes meeting the requirements can be produced; and then, the step-by-step warps that stop working are started, and mesh production continues to repeat the above processes continuously and circularly in sequence. The production efficiency of the hollow weld net produced by the automatic forming method is greatly improved, and the machining precision of the productis accurate.

Description

technical field [0001] The invention belongs to the field of welded steel mesh processing, in particular to the processing of hollow welded mesh. Background technique [0002] Welded steel mesh is a mesh in which longitudinal steel bars and transverse steel bars are arranged at a certain distance and are at right angles to each other, and all intersections are welded together by resistance spot welding. It is mainly used in reinforced concrete structures. The hollow welded mesh is designed to adapt to the influence of structures such as bosses, caissons, especially doors and windows in prefabricated residential concrete panels during the paving process, and holes are opened on the entire mesh to meet structural needs. In the traditional processing method of welded mesh, the whole welded mesh is manually cut after the production is completed, and the cut material cannot be used, and it is only treated as waste material. The waste is large, not only poor in economy but also lo...

Problems solved by technology

However, the warp and weft threading methods of this method are artificially distributed threading, which can only solve the problem of poor economy, but cannot meet the problem of continuous production of equipment and low production efficiency.
