Welding device, use thereof as a control valve, and metering device
Abstract:
A welding device for the sealing welding of thermopolastic hoses (184), includes 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 devices (38; 40; 64) which is coupled to a control unit (30) and is configured to heat 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 with 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 device.
Abstract(Chinese):

一种用于热弹性软管（184）的密封焊接的焊接装置，包括具有至少两个夹爪（122,124）的夹紧装置（12），其中至少一个可移动，并且其中一个软管（184） 被夹紧的待被焊接的夹持装置（12）具有加热装置（38; 40; 64），所述加热装置联接到控制单元（30），并且构造成加热夹在夹爪 124）。 本发明的区别在于，至少一个可动夹爪（122）可与可控的双向致动器（32,34; 42-52; 54,56,58）致动，该致动器联接到控制单元（30） 可以独立于加热装置来调节作用在软管（184）上的夹紧压力的方式。
