Description

They are soldering machines with intermittent solder feed and cooling of the solder joint by means of Compressed air known.

To the. Consumption, according to the compressed air Restrict possibility to. comb is after of the invention with a sliding soldering iron, of the movement of the intermittent Feed of the soldering material is derived, a shut-off device for the cooling air line in such a way brought into movement context that the supply of cooling air while pausing of the soldering iron is interrupted at the soldering point.

In the drawing, an embodiment of the invention is shown.

It shows:

Fig. 4 is a plan for Fig. 3.

At the upper end of a machine frame α (Fig. 1), which for the sake of simplicity carries an attachment plate not shown for the objects to be soldered, a substantially cylindrical soldering iron c is arranged in a vertical bore b , which is heated, for example, by gas. In a

Toothing c ^{1 of} this piston c engages a toothed sector d which is attached to a rotatable shaft Φ and is provided with a hand lever d ¹ and an arm d- . At the end of this arm rf ^{2 there} is arranged an adjustable and lockable finger e which acts on a bolt f ¹ sliding in a vertical guide / of the machine frame a. At the lower end of this bolt Z ¹ is a crosshead / ²

ίο attached, which is under the influence of two tension springs g (Fig. 2) and which carries a spring-influenced pawl h. This pawl h engages a ratchet wheel 'I , which is mounted with a feed wheel i ¹ on a downwardly projecting tab a ^{1 of} the machine frame α. Shaft / ^{2 is} attached. A table k is provided under the feed wheel V , on which the from. a supply roll / unwound soldering material in wire or tape form is advanced to the soldering point χ.

It is useful to place the pad for the solder to be advanced in the table k, e.g. B. by inserting a leaf spring to be flexible, so that the solder can always be safely detected and advanced ^{by the wheel Z 1.}

On the back of the soldering iron c is screwed into a longitudinal groove b ' ^{2 of} the guide b protruding pin c ² , which in its deepest. Position closes a hole m , which is passed transversely through the head of the machine frame α . A compressed air line is to be connected to one end of this bore m , while a nozzle λ 'extends from the other end and points to the soldering point χ .

If the hand lever d ¹ out of its indicated by a dash-dotted line. The rest position is pivoted forward into the position shown in dotted lines, so when the resulting downward movement of the soldering iron c the cooling air supplying hole m is completed when the lower heated end of the soldering iron approaches the soldering point χ , since the pin c ² slides into the Bore m moved into it. The solder pushed forward over the edge of the table k is then melted off by the piston c for the soldering process, and after the soldering point has been completed, the hand lever d ^{1 is} put back again. As soon as the thereby withdrawn, heated end of the soldering iron c has risen slightly above the soldering point χ , the hole m is released again through the pin c ² , and an air stream immediately emerges from the nozzle η , which strongly cools the soldering point χ. At the end of the backward pivoting of the hand lever d ¹ , the finger e of the arm d ~ pushes the bolt f ¹ down, so that a piece of the solder is again advanced by the pawl h with the mediation of the ratchet wheel i and the feed wheel I ¹ on the table k.

Claims (2)

Patent Claims: 1. Soldering machine with a movable soldering iron in a guide and with absatzwaiser solder supply and cooling of the soldering point by means of an air stream, characterized in that with the displaceable soldering iron (c), from whose movement the intermittent advance of the soldering material is derived, one into the cooling air line ( m) built-in shut-off device (c ² ) is related to movement in such a way that the supply of cooling air is interrupted while the soldering iron (c) remains at the soldering point (λγ). 2. Apparatus according to claim 1, characterized in that the upward and downward movable soldering iron (c) is equipped with ^{a pin (c 2} ) which projects into a longitudinal groove (ö ² ) of the frame («) and which finally moves downwards Lays like a slide in a cross hole (m) that penetrates the machine frame (ff) and the cooling air supply line is switched on.
