    • The present invention relates to a mobile seam welder and to a method for controlling the welding operation thereof. A mobile resistance seam welder of the present invention comprises an upper control unit (110) and a lower control unit (120) for synchronizing the movement speed of a mobile unit and the rotating speed of an upper disk electrode (101) and of a lower disk electrode (101'). The upper control unit (110) and the lower control unit (120) comprise: respective first measuring units (111, 121) for measuring the driving force (F1) produced by the friction force between the upper and lower disk electrodes (101, 101') and a welding target (m); respective second measuring units (113, 123) for measuring a force (F2) resistant to the rotation of the upper and lower disk electrodes (101, 101'); and first and second motor force determining units (114, 124) for determining the driving force (F3) of upper and lower servomotors (107, 107') such that a condition (F1>F2) in which the measured driving force (F1) is always bigger than the measured force (F2) is achieved in order to prevent slippage between the disk electrodes (101, 101') and the welding target (m). The first and second motor force determining units (114, 124) determine the driving force of the upper and lower servomotors (107, 107') such that the force (F2) resistant to the rotation of the upper and lower disk electrodes (101, 101') has a minimum value in accordance with the static friction force and kinetic friction force which are calculated by the torque values of the upper and lower servomotors (107, 107'). According to the present invention, the speed of the mobile unit and the speed of the disk electrodes are synchronized in spite of the variation in the outer diameters of the disk electrodes, to thereby maintain welding quality at a constant level and to thus improve welding performance.

    • The present invention relates to a double-structure hose and a terminal device thereof. The invention comprises an external hose (102) and an internal hose (104) positioned therein. At least one supporting baffle plate (106) is arranged between the internal hose (104) and the external hose (102). Therefore, a transfer passage (A) is formed through the internal hose (104) and a transfer passage (B) is formed between the internal hose (104) and the external hose (102), thereby transferring different fluids or gases by separating the fluids or the gases from each other. In addition, a terminal device (200) connected with the external hose (102) and the internal hose (104) is provided. The terminal device (200) comprises a cylindrical body (210), wherein the body (210) is combined with a 1st cover unit (220) for coupling one end of the body (210) with the external hose (102) and a 2nd cover unit (230) for being coupled with the other end of the body (210) and receiving a drawing unit (234). The drawing unit (234) is equipped with a drawing shaft (234b) of which one end is connected to the internal hose (104) and the other end is connected to an internal hose nipple (236) so that fluids or gases transferred through the transfer passage (A) can be transferred. Furthermore, the body (210) comprises an external hose nipple (240) to supply the fluids or the gases transferred through the transfer passage (B) to the outside by forming a mounting hole (216) on the body. According to the present invention, a hose tangle is prevented during work, and consequently the invention has the benefits of improving working efficiency and easily drawing different fluids or gases by separating the fluids or the gases from each other.
    • 本发明涉及一种双层结构软管及其端子装置。 本发明包括外部软管(102)和位于其中的内部软管(104)。 至少一个支撑挡板(106)布置在内部软管(104)和外部软管(102)之间。 因此,通过内部软管104形成传送通道(A),并且在内部软管(104)和外部软管(102)之间形成传送通道(B),从而通过将不同的流体或气体分离 流体或彼此的气体。 另外,提供与外部软管(102)连接的端子装置(200)和内部软管(104)。 终端设备(200)包括圆柱体(210),其中主体(210)与第一盖单元(220)组合,用于将主体(210)的一端与外部软管(102)连接,第二盖单元 覆盖单元(230),用于与主体(210)的另一端联接并且接收绘图单元(234)。 牵引单元(234)装备有一个牵引轴(234b),其一端连接到内部软管(104),另一端连接到一个内部软管接头(236)上,使得流体或气体通过 转运通道(A)可以转移。 此外,主体(210)包括外部软管接头(240),其通过在主体上形成安装孔(216)来将通过传送通道(B)传送的流体或气体供给到外部。 根据本发明,在工作期间防止软管缠结,因此本发明具有通过将流体或气体彼此分离而提高工作效率和容易地吸收不同流体或气体的优点。
