Abstract: A joining tool unit including a hold-down device, a linearly movable tool, and a tool counter element. The hold-down device and the tool counter element are provided opposite each other, a workpiece lies on the tool counter element when the workpiece is arranged on the joining tool unit, and the hold-down device is arranged to be supported on a surface of the workpiece. The hold-down device has a light-guiding system, and the light-guiding system is designed to guide a light beam of a light in the direction of a joint location of the workpiece when the workpiece is arranged on the joining tool unit. The light-guiding system is provided on the hold-down device such that the light beam is irradiated onto the joint location solely at an angle which is greater than 0° relative to a movement axis of the linearly movable tool.

Abstract: A joining tool unit including a hold-down device with a movable tool and a tool counter element. The hold-down device together with the movable tool and the tool counter element are provided opposite each other. A workpiece can be positioned between the hold-down device and the tool counter element in the arranged state. The movable tool and the tool counter element interact in order to form a joint connection. A light-guiding system is formed on the hold-down device, to conduct a light beam in the direction of a joint location of the workpiece when the workpiece is arranged on the joining tool unit. A flow channel for a fluid is defined along a section of the light beam up to a workpiece-side end of the hold-down device.

Abstract: A process monitoring method for monitoring the joining of at least two workpieces by means of a self-piercing riveting device having a joining gun including a) a total sheet metal thickness, a rivet length and a bending constant of the joining gun are detected for a plurality of joining operations for each operation before joining; b) a punch path for a certain force, an end force, a path end value for the end force, a setting path of the rivet, and a rivet head end position are detected for the plurality of joining operations; c) a force/path window for the joining operations is determined; and d) a determined force/path window of one additional joining operation is compared to the force/path window of the joining operations determined in step c), and the additional joining operation is monitored so that any joining-related defects are identified.

Abstract: The present invention relates to an adapter element for attaching a die holder to a tool clamp, in particular, for attaching a die holder to a joining clamp. The adapter element is characterized in that the adapter element comprises a mounting element and the mounting element is designed to arrange the die holder, the adapter element having mounting mechanisms, the mounting mechanisms being designed to arrange the adapter element on a connecting mechanism of a clamp bow of the tool clamp such that automatic attachment of the adapter element to the clamp bow and/or automatic release from the clamp bow is realized.

Abstract: A die for a device for joining is proposed, wherein at least one monitoring element for monitoring the functionality of the die is attached to the die, wherein the monitoring element comprises a strain gauge, wherein the monitoring element comprises exactly two sensors, wherein the spring means have a cross spring with multiple elastically movable spring arms, wherein one die portion is assigned to one spring arm, and wherein the spring arms are connected at one point, wherein the die has four movable die portions which are elastically movable in each case by means of one spring arm of the spring means.

Abstract: A method for producing containers (10) filled with liquid, more particularly drinks containers, wherein plastic preforms are shaped into plastic containers (10) by means of a shaping device (2), these plastic containers are transported to a filling device (4) and are filled with a liquid by means of this filling device, wherein, on their transport path between the shaping device (2) and the filling device (4) the containers (10) are cooled, at least partly, by being charged with a liquid medium. According to the invention the containers are transported, at least during filling, within a clean room (20) which is delimited from an environment by means of a sealing device (62).

Abstract: The invention relates to a device (100) for sterilizing plastic parisons (1), with a sterilization chamber (3) and a transport device (2) disposed at least partially inside the sterilization chamber (3) for moving the plastic parisons (1) within the sterilization chamber (3), wherein the transport device (2) has at least one gripping system (4) for engaging round and supporting the plastic parisons (1) by means of a gripping clamp (41), wherein the gripping system (4) has a displacement means (5) for displacement during sterilization within the sterilization chamber of contact surfaces (1A) of the plastic parisons (1) which are shielded by the gripping system (4) from a sterilizing medium and/or sterilizing radiation.
