Purpose of innovation ist.es ₉ is a blind rivet pliers train this genre "that * sis as possible ', easy, simple, 4m. Construction, less prone to interference and "is cheap to produce." This is achieved by-the firing system thereby ". That the first baking on the. Outside © in pierced Mund'stück sum A '·. Push the Durchzugsdorass bears, and" that the aweit. Jaws are fork-shaped and each of their fork legs has a "clamping sleeve-containing" block rotatable on pumice ·

The pliers after firing consist of a very small number of τοπ parts, which are also easy to manufacture and assemble. It is also robust and has a long service life »

Appropriately, the conical clamping jaws susaiamengesetste clamping sleeve protrudes on both sides from the Klötsehen _s whereby it can be brought into an open position by pressing the yorderen end against the inside of the first jaw and is loaded at the rear end by a spring in the Ilemmsinn.

To open the pliers, the jaws are moved towards each other so that the clamping sleeve rests against the first jaw and is opened. laughing inserting the Durchzugsdornes- * the jaws are moved apart "The case slightly shifted by the spring immediately Ilemmhülse detects the Dorn'zuverlässig and secure. Working with the new blind rivet pliers is therefore extremely easy.

When the Klötzchen'in ISTJ mounted to the fork legs backlash then the jaws result when operating the pliers pivot about the common pivot axis "The blocks" moved check in Backenbewegimg on a circular arc about the pivot axis when the arc is also very flat, so is the block has been moved to a certain extent out of the extension of the hole in the mouthpiece ». Because the Digßchsugsdorn of the blind rivet is on the one hand in the straight bore of the mouthpiece and on the other hand in the gill sleeve

chen's is held, 'the pulling mandrel is bent slightly by the sideways movement of the block. Upon completion of the lietTorganges the pulling mandrel breaks in the area dee mouthpiece and has to be m the tongs fall out, "If that 'torn off Abshhnitt of pulling mandrel has a kink, it can deposit that ®τ caught in a clinch and only. herds can be brought out of the tongs by shaking them a little or by using an auxiliary device »

This difficulty can arise after an important training course the innovation can be avoided in that the block in the fork does not give in the direction of the pivot axis. too sufficient-- ' Game for moving the block in a straight line with sur drilling: im Mouthpiece of coaxial clamping sleeve during the entire - pliers movement Has.

Since the block in this case has to play in the fork legs in the direction of the pivot axis of the jaws, "it does not need to move on a circular arc sn" of the 'block with the IClema sleeve caused kink ¹ against a resistance, which in the pliers according to the invention -dzu.'. so that the block moves in a straight line, let the clamping sleeve remain constantly coaxial with the bore in the mouthpiece. " the

A flexible dee suction mandrel when riveting is greatly reduced, so that the tool can easily fall out of the pliers.

With complete certainty, bending of the purch-

The G-eradführungorgane can be created in a simple manner ₉ that straight guide rails running in the direction of the hole in the mouthpiece are seen in the U-legs, and sliding shoes are attached to the side of the block, which engage in the guide rails and the fork handles in enforce elongated holes directed towards the swivel axis below.

Another way to prevent the mandrel from bending when riveting, is that the hole in the. Mimdstück look auconically extended towards the block.

The conicity of the bore can, however, be provided to support fkUGh if the other described features are realized .Bind. · ·
