WELDING DEVICE, USE THEREOF AS A CONTROL VALVE, AND METERING DEVICE
Document Type and Number:
WIPO Patent Application WO/2012/062395
Kind Code:
A3
Abstract:
The invention relates to a welding device for the sealing welding of thermoplastic hoses (184), comprising a clamping device (12) with at least two clamping jaws (122, 124), of which at least one is movable and between which a hose (184) which is to be welded can be clamped, wherein the clamping device (12) has a heating means (38; 40; 64) which is coupled to a control unit (30) and is intended for heating the hose clamped between the clamping jaws (122, 124). The invention is distinguished in that the at least one movable clamping jaw (122) is actuable by means of a controllable, bidirectional actuator (32, 34; 42-52; 54, 56, 58) which is coupled to the control unit (30) in such a manner that the clamping pressure acting on the hose (184) can be adjusted independently of the heating means.
