Problems solved by technology
Chains don't have the problem of pretensioning for short operating times compared to belts, but chains tend to stretch over time due to wear
[0009] Moreover, since the traction device is loosened on one side, it has the disadvantage that its drive is no longer as reliable as the drive gear
Moreover, the pulling device may also fall out of the guiding device, so the correct operation of the vibration welding device cannot be guaranteed

Embodiment Construction
[0047] The following description of the puller tensioner of the present invention is based on its use in a vibration welding device. However, this use is not limiting. Because, the traction device tensioner according to the present invention can be used in any device or machine that uses a traction device to achieve reciprocating movement of elements. In particular, the continuous traction device which only realizes the reciprocating movement of the elements can be replaced by the traction device of the present invention, the two ends of which are combined with the traction device tensioner.
[0048] refer to figure 1 , which depicts a vibration welding device 1 . The vibration welding device 1 includes a frame 10 having an oscillating head 12 and an elevating table 14 . The lift table 14 is guided in the vertical direction by means of guide columns 16 and support sleeves 18 . During the operation of the vibration welding device 1 , a workpiece to be welded is respectively...

The invention provides a traction tensioner, a vibration welding installation apparatus with the traction tensioner, and a method for producing the traction tensioner. With the traction means tensioner, a traction means having at least two ends is tensionable. The traction means tensioner comprises a first fastening means, a second fastening means and a coupling means. The first fastening means has a first fastening portion at which the first end of the traction means as fastenable. The second fastening means has a second fastening portion at which the second end of the traction means is fastenable. The coupling means couples the first and the second fastening means to each other so that the first and the second fastening means are movable with respect to each other and their movability is at least restricted on one side. Further, the first and the second fastening means are pretensionable with respect to each other via at least one spring element.
Description
technical field [0001] The invention relates to a traction device tensioner, the use of the traction device tensioner in a welding device, a vibration welding device with a traction device tensioner, a method for manufacturing the traction device tensioner, a welding device modification method and a traction device tensioning method . Background technique [0002] In the past few years, electric drive vibration welding devices have gradually occupied the market. The vibration welding system (especially the oscillating head) of the vibration welding device is usually driven electrically. In contrast, the propulsion systems of vibration welding systems have for a long time been operated hydraulically and in rare cases pneumatically. The term "propulsion system" here includes all movable elements of a vibration welding device that move or screw a first workpiece to be welded to a second workpiece to be welded, which are arranged on an oscillating head. For example, lift tabl...
