The upper and lower track shoes are the core of the double-track press, and the design, material selection, machining, and processing process are very important and very complicated. The double-crawler machine is installed in the continuous production line for the foaming and curing of the core material of the sandwich panel, and the curing and shaping of the sandwich panel in the laminated state.
When the track shoe is in working condition, it must be under long-term pressure (foaming pressure is 3kg/cm2) and temperature resistant (working temperature is 45ºC-80ºC), especially when producing PIR and phenolic, the temperature of the track shoe can reach 70ºC. When the two conditions are combined, the track shoe metal will experience creep in long-term work, which will deform the track shoe, destroy the geometric accuracy of the track shoe, and affect the surface quality of the composite board. In view of the above situation, this track shoe adopts high-quality special materials. The processing technology of the double track machine adopts multiple heat treatments to relieve stress and annealing. At the same time, it finally adopts grinding processing and complex welding processing technology. The special two-stage transmission design makes the track shoe The width of the track shoe can reach 270mm. Through finite element mechanics analysis and the special reinforced structure design, the track shoe has a high hardness, good wear resistance and unchanged shape; the above conditions ensure the rigidity, strength, and fatigue resistance. And weather resistance to prevent metal creep.
The function of the side belt is mainly to overcome the transverse tension generated by the polyurethane foaming, determine the width of the composite board, and play a precise guiding role for the composite board during the production process; the double track is used as a continuous running movable mill, which needs to avoid plate deformation and The surface is scratched to ensure high-quality composite panels.
