Description

20 or the overall focus of the spring elements 7 lying in the holders and the holders self.

The intersection of the connecting line 33 and the center line 32 is the starting point for the radius R. The radius R is that of the ball of the ball joint, which consists of parts 3 and 3 α.

If the stamp is tilted in the direction of the coal face or the old man, the The intersection of lines 32 and 33 does not have its position in space. However, if the holder 9 and 10 on one side opposite the holders on the other side can be adjusted to change the target position of the stamp in the sense of a given inclination in contrast to the collapse to achieve lead the centers of the holders 20 from a practically exact vertical movement.

In any case, a trouble-free movement of the ball joint is achieved.

In addition, the holders 20 are attached to the punch guide at the same height. How in particular the plan view reveals that the connecting line runs perpendicular to the parallels of the spring bar elements.

In the . Stamp receiving housing is a hydraulic pit stamp 1 α housed. For this purpose The invention relates to a device for connecting the punch receiving housing is open at its upper bearings of a hydraulic pit punch on a 4 ° end. At its lower end it carries a base rail or plate with the aid of a sub-spherical head 3, the receiving housing enclosing part of a ball die, which is a joint, the other part of which is connected to a ball joint on the base rail or the base cap 4 formed socket bearing 3 a ge -plate is mounted pivotable on all sides, is formed in. Holders of the stamp receiving housing attached 45 On the two legs of the U-shaped part 2 spring bar elements on both sides of the stamp on the stamp receiving housing are attached outside two holder housing approximately perpendicular to the stamp axis. In the representation of the drawing is running and are arranged parallel to each other and only one holder can be seen. Both holders for fixing the spring rod ends in front of and behind. and their individual parts are identical on the opposite sides of the stamp to the stamp receiving housing on the sole rail 50,
or plate holders are arranged, which are individually In the holder 20 with the help of a heavy-duty perpendicular to the sole rail or plate and essentially pin 21 a package of spring bar elements 7 exposed Adjusted parallel to the punch holder housing.

The holders 9 and 10 can be swiveled back with the desired position, these being adjusted according to the height of this device.
Divide the pit according to the collapse 60. Such an adjustment can give the punch a preload. in all directions opposite the sole rail The invention solves the technical problem that is aggravated.
