Method for cooling resistance welding machines, in particular water cooled spot weld guns, and apparatus for performing the method

摘要

the invention concerns a method for cooling widerstandspunktschweiu00dfanlagen, as well as a device for implementation of this procedure.;in the area of the electrodes verfahrensgemu00e4u00df is only a ku00fchlwassermenge supported if there for cooling during welding is needed. thus, a continuous flow ku00fchlwasserstrom, but one with the setting of each point zugemessener pulse. between the operating welding processes, the cooling water is not or only geschwindigkeitsvermindert moved.;the establishment of it is a zylinderkolbeneinheit (7) in which a fu00f6rderkolben (9) to the pump room; (12) limited, whose volume corresponds to the ku00fchlwasserbedarf one welding process. the fu00f6rderkolben (9) is connected with a motor drive, preferably a coaxial arranged pneumatic drives.;advantages of the invention are the optimal cooling of the electrodes and ku00fchlwassereinsparung, reduction of the costs for ku00fchlmediumversorgungs infrastructure, standmengenerhu00f6hung and increase process reliability.
