Guided tour for pole feeder gates

The present innovation "relates to a guide for automatic bar feeders, "which the rods are gradually advanced to automatic Machine tools to be supplied in which the machining of the bar is carried out.

As is known, the rod guide in rod feeding devices for automatic machine tools is formed by parts lying against one another in the longitudinal direction, of which the lower part is stationary with the
Frame of the feeder magazine is connected. during the

7600879 11/25/76

other part designed to be liftable in relation to the lower part is to allow the import of a new rod.

Particularly in the case of long and thin Stan xxad of machining operations in which the rod is rotated at high speed, there is noise-generating bumps and hitting of the rod in the guide, which is particularly annoying for the staff responsible.

11 Il ■ "

Due to the renewal according to the leadership, a curtain is now Iting and attenuation of the noises achieved by the bumps and blows that scream on in the leadership tend or rotatable rod are formed, and at the same time should be prevented · that the noise in the work area spread.

That goal is achieved with a guide for rod feeders achieved, which is characterized according to the invention in that it has two in the longitudinal direction has leaning parts, which each consist of an inner Ealb_ jacket and an outer half-liner as well as a filling consist of sound-absorbing and steaming material, whereby the filling between the half-cover and the half-man tel is arranged and connects them with each other »

Further details of the.! Inflation are clearer from the description of a guide for bar feed devices are shown in the accompanying drawing is placed in vrelcher:

Fig. 1 is a perspective view partly in view; one of the parts of the renovation according to the innovation, whereby a

Figures 3, 4 and 5 are three further transverse views of part of a guide.

Kit referring to these figures are the two parts that make up the feed guide for a rod in one automatic bar feeding device for automatic machine tools is elongated, denoted by 1. One of the parts 1, e.g. the lower part, is fastened in a manner known per se to the frame of the feeding device, while the other part is movable with respect to the first, so that it is normally placed on this

can be and the guide passage 2 closes or else can be removed transversely from the first part, the guide passage being opened and the introduction into the same the rods is made possible. The two parts 1 are also in a manner known per se, practically the same and symmetrical with respect to a horizontal plane which is passed through the Axis of the passage 2 äurchgehi formed.

Each part 1 consists of an inner half-jacket which is divided into a number of sections 3 in the longitudinal direction which are slightly spaced from each other, and consist of an outer half-shell 4 and a filling 5, which are arranged between the bellows and the half-mantle is"

The sections 3 consist of stiff, and wear solid material, preferably made of a metallic material such as cast iron, steel or bronze j the half-cover 4

is made of the same material as sections 3. The filling 5, however, consists of a sound-absorbing

and dampening material, preferably made of rubber or other elastomers.

In Figures 1 and 2, the cross section is

The anchoring of the sections 3 to the filling 5 is through the holes 6 favored, which are present in the legs 3 a and filled with this when pressing the filling

The same function as the holes 6 have Indentations 7 of the sides of the shaped bars which form the sections 3 of FIG. 3, these shaped bars according to have on the outside a concavity with a semicircular cross-section to form one half of the passage 2. the Sections 3 of Fig. 4, however, consist of profile parts

with a semicircular cross-section and are with the filling

In Fig. 4, the half-casing 4 just like that Sections 3 still have a semicircular cross-section and it is connected to the filling 5 by adhesives.

In FIGS. 1, 2, 3, the half-cover uzig 4 almost completely encloses the filling 5; this cover namely asked for a box-shaped cross section with two to one another

7600879 11/25/76

corresponding curved sections 4a, which extend into the vicinity of the sections 3.

In the embodiment variant of FIG. 5, the inner half-mantle a U-shaped throat, so that. . It can be locked by an upper flat part and the Formation of connections that can always give rise to sharp edges that damage the bar to be machined, is prevented.

It can now be seen that each of the
