Description

The The invention relates to a device for inserting a sieve plug in a square drum, the drum shell of flat plate sides is formed, and their use in particular in electroplating

The Galvanization of small bulk solids can be done in immersion drums between the plating electrodes.

From the DE 22 51 507 A1 It is known to use a drum with octagonal outer shell, on the surface of exchangeable plastic sieves are used (page 6, last paragraph).

From the DE 23 61 683 A1 It is known that the immersion drum has mutually conical perforation holes. It is essential that the perforation holes on the one hand should be as large as possible so that the electrolyte exchange is as large as possible, and on the other hand so small that the small parts can not slip out of the drum.

From the DE 38 37 214 A1 It is known to insert round or square Siebstopfen in the galvanizing drum.

Also from the DE 26 57 535 A1 is the use of Siebstopfen known; This document states that the insertion of the plug into the bores is time-consuming (column 1, line 56).

Of the Replacement of the Siebstopfen usually takes place for the first time at the unfolded Drum jacket by even impressions, wherein also here often Canting occur. When the drum is closed is usually a page for filling and for Service work opened.

There Sieve plugs in pressure of small parts at galvanization have to withstand they are pressed from the inside under tension in designated holes.

If Siebstopfen be replaced, or defective replaced have to, the insertion usually has to be done with the help of a hammer, to reach from the inside of the drum, the plugs and the necessary To apply force. This often occurs tensions and tilting on, which lead to the loss of the plugs.

task The present invention is the provision of a device, the tension-free insertion of Siebstopfen in the submerged drum allows.

It was a device for inserting Siebstopfen in a square drum, the drum shell is formed of flat plate sides,
wherein one of the plate sides is opened and the other plate sides are provided with interchangeable screen plugs,
containing a pressing part with two counter-acting pressing jaws,
wherein one of the pressing jaws of the pressing member can be inserted through the open plate side of the drum up to each of the screen plugs and the second is located outside the drum,
wherein the inner pressing jaws has a receiving bolt for a sieve plug and the outer pressing jaw has a pressure pin acting against it.

With Help the device of the invention is it without big Time effort easily possible, Siebstopfen without bracing and tilting in the openings provided to insert the drum shell.

In As a rule, the drum is on a rotation axis, with the Rotary axis is laid through the side parts of the drum.

The Drum is usually used in the electroplating of finely divided objects used. Finely divided parts here are parts with a diameter from 0.3 to 10 mm.

The Drum has a drum shell with flat side panels. In the Usually the drum can be four- to octagonal. For the application the device according to the invention hexagonal drums are preferably used, with five sides of the Drum mantle are closed.

The Siebstopfen are in recesses of the closed sides of the drum shell are attached. The Siebstopfen sit close to the closed Sides of the drum shell and fill prefers it.

The Sieve-pot must inserted under tension from the inside into the recesses of the drum shell become.

The Siebstopfen usually have a hat-like shape, with the sieve through the opening depressed is, and the edge rests on the inside of the drum shell.

In a preferred embodiment The present invention corresponds to the shape of the locating pin the shape of the inward facing part of the sieve plug.

In another preferred embodiment According to the present invention, the pressure pin has a recess for receiving the Siebstopfens from the outside and an edge, the rests on the drum shell.

The Pressing jaws with the locating bolt and the pressure pin can in Frame of the present invention in various ways against each other depressed become.

In a preferred embodiment According to the present invention, the pressing jaws with levers against each other pressed.

in the Within the scope of the present invention, it is particularly preferred that the introduced into the drum Pressing jaws static and the outside of the drum Anpressbacken movably mounted on a stand, wherein he can be moved so that he is over a selected sieve stopper is located, and wherein the contact pressure by a long lever arm on the outside the drum located pressing jaws is generated.

Around To be able to reach all the sieve stoppers on the drum casing well preferred that, depending on the location of Siebstopfens on the drum shell different length receiving bolts and push pins are used.
