An apparatus of a setting welding device for an auxiliary joining part with a head and a shaft, includes a linear drive fastenable at the setting device and including an element nest at a movable end, in which an auxiliary joining part is releasably receivable from a transfer unit. The element nest is movable by the linear drive in a first direction. The element nest is supported in a floating manner, and is positionable via a mechanical stop alignment in abutment with an electrode punch in the joining direction below the electrode punch. And/or the element nest is connected with the linear drive via a mechanical direction-changing coupling component so that the element nest is movable by the linear drive in a second direction so that the auxiliary joining part is positionable at the joining location, wherein the second direction is not parallel to the first direction.

Element supply apparatus for a setting welding device, an element nest and a retrofit kit for the setting welding device as well as corresponding supply methods of a welding auxiliary joining part

A setting head for a joining device, such as a press or a setting device, which setting head comprises the following features: a punch which is movable in a longitudinal direction such that a joining element can be joined into a component by means of a punch face arranged at a working end of the punch; a hollow cylindrical receiving sleeve which has a through-passage and which, with the punch in the through-passage, is guided adjacent to the working end of the punch concentrically and axially movably thereon; and two mutually opposite holding arms arranged on the receiving sleeve outside the through-passage each provide at least one laterally inwardly projecting holding end, with the result that the at least two holding ends allow the joining element to be releasably positionable adjacent to a punch-remote outlet opening of the through-passage and by the axially movable working end of the punch.

Setting head, sheet metal press or setting device having this setting head, and a method for joining a joining element with the setting head

A spring arm sleeve, with which a joining element of a joining device is positionable and which comprises the following features: a tubular section which is formed by a circumferential or all-round wall, the circumferential wall comprises in the circumferential direction a plurality of U-shaped apertures regularly spaced apart from one another, which form a plurality of one-sidedly fastened spring arms which are inclined radially inwards into the tubular section and extend from a fixed end in a first longitudinal direction.

Spring arm sleeve

A setting device for connecting at least two components includes a first lever arm having a first working end, and a second lever arm having a second working end, that are pivotably connected to each other like pliers. A first linear drive is connected to the first and the second lever arm so that, by changing of the length of the linear drive, the first and second working ends can move relative to each other. A punch is arranged at a first working end that is connected to a supply module for joining elements, and/or a hold-down module.

Setting device, supply module for the setting device, and a joining method for connecting at least two components

The invention relates to a setting device for an auxiliary joining part, particularly a setting fastener or a punch rivet, including a driven punch which for a setting movement can be moved in a joining channel to which the auxiliary joining part can be loosely fed. The setting device includes a head piece in which a part of the joining channel runs, further including a plurality of compressed air ducts ending in the joining channel, and an exhaust air channel. The exhaust air channel ends adjacent to the front side of the punch moving the auxiliary joining part into the joining channel of the setting device such that an airflow can be generated in the joining channel in the direction of the front of the punch moving the auxiliary joining part by way of an overpressure which can be generated in the plurality of compressed air channels compared to the atmospheric pressure and by which the auxiliary joining part can be positioned on the front side of the punch.

Head piece for a setting device

The present invention relates to a magazine of a setting device for storing and feeding a plurality of joining elements, particularly of joining elements, such as setting fasteners, to a provisioning module for joining elements and a setting device in combination with the joining elements. The magazine has a base element within the setting device including a storage groove, in which the joining elements can be received in an aligned and jointly moveable manner and one end of the base element ends in a head piece of the setting device. The magazine further includes an advancing mechanism, by which the joining elements can be moved within the storage groove towards the head piece of the setting device, as well as a dispensing mechanism, by which the joining elements can be fed individually from the storage groove to the head piece of the setting device.

Setting device having a magazine and a provisioning module for joining elements

The present invention discloses a feed apparatus, a feed channel and a setting device, that is used in connection with these specific apparatuses. The feed apparatus uses either a strip magazine or a rotary magazine. The feeding of the fastening elements proceeds stepwise using a movable slide, where with use of the rotary magazine a simultaneous loading and unloading of the rotary magazine at different positions is guaranteed.
