二、料团预压机——联合机的辅助设备料团预压机简称压团机,是用来将拌和好的涂料压制成一定直径与长度的圆柱形料团,它的直径要略小于涂药机的药料筒内径3～4公厘。压团机压制涂料的单位压力要求在100～176公斤/平方公分左右。如果压制料团的压力太低,或者压制的料团因压挤而密度不一,这都要影响涂药机的焊条涂制质量,甚至在涂制时有裂缝的可能;因此料团预压机对焊条制造的质量与焊条表面的光洁度、美观等,均有密切关系。料团预压机大多数是直立式的液压传动压力
Second, the mass preloading machine - the auxiliary equipment of the combined machine group Preloading machine referred to as the press machine, is used to press the mixed paint into a cylindrical mass of a certain diameter and length, its diameter is slightly smaller than the coating The diameter of the drug cartridge barrel is 3 to 4 mm. The unit pressure of the press-pressing paint is required to be around 100-176 kg/cm 2 . If the pressing mass pressure is too low, or the pressed mass has a different density due to crushing, this will affect the coating quality of the applicator electrode, and even the possibility of cracks in the coating; therefore, the mass preloading The quality of welding rods produced by the machine is closely related to the smoothness and appearance of the electrode surface. Mass preloaders are mostly vertical hydraulic transmission pressures
