The invention relates to an iron pit punch without any design, such a punch so recently ict, ilen each punch in the simplest way a preliminary application. .

According to the invention, for this Zv / corner the Koofplatte is separated from the upper die and cefilled with a fixed guide piece, which corresponds to the inner profile of the upper die. Between the Hopf plate and on two opposing sides of the Oöe-rctsmpellcopfGS -assigned slightly inclined slideways forming guide pieces; a thin body is inserted, which has a rectangular opening corresponding to the profile of the opening of the stem of the stem and laterally by a certain amount over the hand the stamp head plate protrudes. By driving this slide on the guideway on the Obersteapel · * the wedge , the punch head plate is raised and pressed against the with a pressure corresponding to the one in which the WBiX is driven.

In this way, the desired pre-tension can be given to a punch that has been set without the aid of a setting device and, if necessary, the pre-tension given to the punch by means of a setting device can be adjusted to a desired level. BarcÄ an attempt to drive in the wedge further, ie * immediately ascertain whether the desired degree of pretension is present, either by means of a vascular or by comparison.

BS is thus a very simple gate direction that replaces a setting device in many areas, especially in less thick seams, where the use of a site device is difficult anyway, or if an all-round pre- tensioning is not necessary and, ' Also an excellent means of monitoring correct setting

Represents stamp.

At the same time, the new device also represents a very simple precaution against robbery. By striking the end of the wedge protruding on the opposite side of the stamp head, the wedge is loosened and, as a rule, the stamp is relieved of pressure to such an extent that it can be stolen .

The inclination of the wedge must be below the angle of the self-locking, otherwise it must be considerably smaller than it is, fully once the Hegel only takes a very short vertical path by which the punch head plate is raised, on the other hand, too If the wedge is steep , the forces for driving the wedge will also be too great. Furthermore, the distance that the wedge has to cover in a lateral direction will then be relatively large, so that the extent by which the wedge has been driven in can be more clearly recognized externally.

The new stamp can be used generally for longwall mining; It offers special 1 advantages when mining less thick seams, ie for comparatively short punches, for which the wedge to be driven between the punch head plate and the upper punch is fully sufficient as the only setting device.
