Quiet and beautiful pu castor role in our lives is very big
Quiet beautiful polyurethane casters in the life of the role is very big, for heavy duty castor bracket and the selection of bearing, chongqing heavy duty castor technology factory workers: usually castor choose suitable wheel rack first consider the weight of the caster wheel bearing such as supermarkets, schools, hospitals, office buildings, hotels and other places, because the floor is good, smooth lighter, and handling of goods ( Each trundle bearing in 10 - 140公斤) , suitable to select (with a thin plate 2 - 4mm) Stamping wheel rack plating, the wheel frame is light, flexible operation, quiet and beautiful, the plating wheel frame in accordance with the ball bearing arrangement is divided into double row bead and single bead. If often move or application of double row in the bead. In the place such as factories and warehouses, cargo handling very frequently and heavier load ( Each trundle bearing in 280 - only 420公斤) Chooses to suitable for thick steel plate, 5 - 6毫米) Stamping hot forging and welding of double row ball wheel. Cold castor riveting method that comes natural flow bend deformation of the rivet to metal, will not reduce the notched impact toughness and ductility of material, reduces the rivet and a tangential tensile stress around the pier head too high, the danger of no broken fiber material flow after riveting, can improve the bearing capacity of the rivet. Will swing cold grinding with traditional stamping hammer, castor castor riveting riveting do destructive test specimens after know, cold run castor riveting method produced by the coupling strength is about 80% higher than that of traditional castor riveting. After cold run castor riveting rivets almost no deformation phenomenon such as bending, drum abdomen, pier crude. At the same time, connected to the rivet parts without deformation. With stamping hammer, castor riveting, since it is case pressure, impact in full bloom, the defect is more obvious. Castor riveting combination pliers combination pliers castor riveting traditional process is to use an electric heating heat rivet and rivet, hot riveting not only large energy consumption, More than 20 kw) , and rivet easy scale, efficiency is low. Blunt riveting, although high efficiency, easy to rivet central upsetting, looseness is not easy to guarantee, and great noise, nor safe operation. Cold run castor riveting overcomes the above all just end. The country more than 20 combination pliers factory adopted the cold run over my company castor riveting machine, greatly improving the quality and reduce the cost.
