Abstract

A drawing die (3) is arranged outside a drawing reservoir (5), with a channel (4) arranged between the die and the reservoir. A non-return valve (2) is arranged in the channel.

Description

The The present invention relates to a wire drawing device from a drawing container and a drawing die, in which the drawing die is arranged outside the drawing container is.

Drahtziehvorrichten are used for reducing, especially for calibrating wire cross-sections used. As a rule, these wire drawing devices have at least one for this a drawing die, which according to the prior art in one filled with a drawing medium drawing tank located. Accordingly, the drawing die is difficult to access. Even if the drawing medium is removed to remove the drawing die from the drawing container this work remains a dirty, dusty affair.

task In the present invention, it was therefore a wire drawing device to disposal to provide, which does not have the disadvantages of the prior art.

Is solved the task with a wire drawing device according to claim 1. Preferred embodiments the wire drawing device are claimed in subclaims 2-5.

According to the invention the drawing device has a drawing container and a drawing die, the drawing die is not arranged in the drawing container. With the Drawing die is the actual reduction or calibration of the cross section of the wire. The so-called is located in the drawing container Drawing medium with which the drawing die is lubricated and one liquid, doughy or powdery May have physical state. The pulling device according to the invention can have multiple drawers and / or have several drawing dies.

Preferably is between the draw tank and arranged a channel through the drawing die through which the drawing medium from the drawing container flow to the drawing die can. A blocking member is very particularly preferred in the channel, preferably a check valve, arranged so that the fluid connection between the draw tank and the drawing die can be interrupted.

Preferably the drawing die is a locking device in relation to the running direction of the wire downstream, so that leakage of the drawing liquid is avoided.

Preferably the drawing die is stored in a drawing unit, the drawing die unit is preferably designed so that the drawing die is simple, especially preferably be replaced without the use of tools can. Furthermore, the drawing unit is preferably designed such that it can hold drawing dies of various shapes and sizes.

All the drawing die is particularly preferably away from the drawing container pivotally arranged. this makes possible a very easy exchange of the drawing die because of this very well accessible is.

The wire drawing device according to the invention simple and inexpensive produced. The drawing die can be exchanged very easily, without the drawing medium having to be removed from the drawing container, which means a significant time saving. The operating staff will when changing the stone less dirty and / or less dust exposed.

In the following the invention based on 1 explained. These explanations are only examples and do not limit the general inventive concept.

In 1 is the wire drawing device according to the invention 1 shown, which is essentially a draw tank 5 and a drawing die 3 having. The pull container is designed to be removable. In the drawing box 5 there is the drawing medium, which over the outlet 7 from the drawing container 5 can run. The pull tank is across the channel 4 , for example a pipe with the drawing die 3 connected so that the drawing medium from the drawing container 5 to the drawing die 3 can flow. In the channel 4 is the valve 2 arranged so that the flow of the drawing medium can optionally be prevented. The drawing die 3 is in a drawing unit 6 arranged from two parts 6 ' and 6 '' that is over the joint 8th and the sealing agent 9 are interconnected. The part 6 '' is with the channel 4 connected. The part 6 '' in which the drawing die 3 is stored, after loosening the closing means 9 can be folded down so that the drawing die can be removed easily and can even be ejected automatically. Between the parts 6 '' and drawing die 3 is a seal 10 arranged so that no drawing medium escapes. This seal is preferably designed so that a wide variety of drawing dies can be sealed with great tolerances.

To pull a wire, the drawing die becomes 3 into the drawing unit 6 inserted and this with the sealing agent 9 locked. The removable drawing container is filled with the drawing medium on the channel 4 put on and the valve 2 open. The pointed wire is inserted into the drawing die and the drawing process of the wire can then begin.

The valve is used for cleaning or changing the drawing die 2 closed, the closing means 9 opened and the drawing die removed men.
