Description

Automatic net rolling equipment for welding reinforcing steel bar welding net sheet for ballastless track Technical Field The invention relates to the field of welding of reinforcing steel bar meshes, in particular to automatic mesh rolling equipment for welding of reinforcing steel bar welding meshes for ballastless tracks. Background The ballastless track is used as a core structural form of a high-speed railway, the smoothness and the durability of the ballastless track directly determine the running speed and the safety of a train, and in the prefabrication production of the ballastless track plate, a steel bar welding net sheet is a key framework material for bearing load and providing prestress; At present, the main stream of reinforcing steel bar mesh welding equipment in the industry mostly adopts a planar grid type welding process, and the process generally comprises the following steps of firstly spreading longitudinal bars and transverse bars on a horizontal welding platform, compacting the crossing points of the longitudinal bars and the transverse bars through a pneumatic or hydraulic clamp, and then performing spot welding fixation by using a resistance welding machine, wherein the technology is mature, but has certain defects when being practically applied to the production of high-precision ballastless track plates: 1. Because high-impedance substances such as rolling oxide skin, rust or greasy dirt and the like are usually present on the surface of the steel bar, in the traditional planar clamping welding, the externally applied clamping force is difficult to completely destroy the insulating layers, so that the contact resistance is overlarge during welding, the heat distribution is uneven, insufficient welding spot fusion is easily caused, defects such as cold joint, off-welding and the like occur, and the whole pulling resistance of the net sheet is seriously influenced; 2. In order to ensure welding strength, the traditional equipment has to rely on huge mechanical pressure to ensure that the steel bars are in good contact, the welding electrode heads are extremely easy to deform, adhere or burn due to high-strength extrusion, frequent shutdown is needed for grinding or replacement, so that maintenance cost is increased, production continuity is broken, and production efficiency is reduced; 3. The steel bar meshes in the ballastless track plate generally comprise main bars and distributed bars with different diameters, the clamp structure of the traditional welding equipment is relatively fixed, steel bars with different thicknesses are difficult to consider in the welding process, the small-diameter steel bars are easy to crush and deform, the problem of displacement caused by insufficient clamping force can occur to the large-diameter steel bars, and the mesh forming precision is difficult to control; 4. The traditional resistance welding generally only heats and pressurizes welding spots from a single direction (above), the single-point welding mode leads to uneven distribution of internal stress of welding spots, and a heat affected zone is larger, so that local metallographic structure change of reinforcing steel bars is easy to cause, and fatigue strength of materials is reduced; In view of the above, in order to overcome the shortcomings of the prior art, it is necessary to provide an automatic net reeling device for welding reinforcement welding meshes for ballastless tracks.
