placed. This is because the holder or container, and its crosshead are mounted direct- 1y on the base frame, so that when the metal 19 expands the expansion is principally in the upward directionl To obviate this, it is proposed according to the invention to provide the "crosshead, on the side furthest from the holder or container, with an extension which is journalled for reception in a bearing advantageously annular and supported on the base frame. This form of mounting'for the holder or container and the crosshead allows expansion to proceed radially and uniform- 'ly, and thus the danger is practically eliminated of the centre of the holder or container being displaced, the journalled extension being subjected scarcely to any heat or expansion, since it is disposed away from the holder or container. Thus the axial disposition of the parts of the press is safeguarded, in Which it differs from other proposals.
The invention is illustrated, by way of example, in the accompanying drawings, in which Figure 1 shows the apparatus in longitudinal. section, and Figure 2 illustrates an end elevation of a part of the apparatus.
Figure 3 is an elevation to a smaller scale ofthe metal extrusion press.
Figure 4 is adetail section of a modified form of the mounting according to the invention.
Figures 5 and 6, are detail end views of modifications of the manner of mounting the crosshead.
The press crosshead is denoted by 1 (Figures 1 and 3), and the holder or container by 2; 3 is the base frame of the press, and 4 the extension provid-edaccording to the invention for mounting the crosshead together with the holder or container The extension 4 is j'ournalled or mounted in a socket ring 5, which at the bottom is 428,978, and in Germany November 24, was.
formed to serve as a support 6. This on turn is mounted in the base frame 3. The crosshead is prevented from being rotated by a wedge 7, or by any other convenient means. The crosshead, and with it the holder or container 2, isprovided of circular shape and so mounted to rotate that any expansion produced by heat takes place radially in all directions, whereby the danger of displacement of the centre of the holder or container is avoided.
.The invention is not limited to the example of construction described and illustrated. For example, as illustrated in Figure 4, the construction may be such that the journalled extension 4 as a part separate from the head 1"is connected by screws or bolts 7 or other securing means to the head 1, a heat insulating layer 8, being interposed.
Furthermore, as shown in Figure 5, instead of the journalled extension 4' being'cylindrical in shape it maybe of non-circular shape, for instance, it may be rectangular. In such a case special means are unnecessary for preventing the rotation of the crosshead. More- 76 over, the bearing, instead of being provided in one piece, may be divided, as shown in Figure 2, the upper portion bein' detachable and being secured in position y means of bolts or the like which pass through lugs 9 80 respectively provided upon the upper and lower portions of the bearing.
In order to permit exact adjustment of the crosshead without difliculty, as shown in Figure 6, wedge members 10 seated in recesses in the ring 5 and also in recesses having inclined surfaces in the extension 4 may be provided for adjusting the crosshead relatively to the press axis.
The invention may be considered quite generally as comprising the mounting of the crosshead by means of a journalled extension or its equivalent.
I claim:
1. In extrusion presses, a container for the metal to be extruded, a crosshead disposed to the rear of and supporting the container, 2. base frame, and a bearing to the rear of the crosshead supporting the crosshead and container andfmounted on the base frame, whereby displacement under expansion of the container from its axial position is prevented. 2. In extrusion presses. a container for the metal to be extruded, a crosshead disposed to 5 the rear of and su porting the container, a base frame, and aaringto the rear of the crosshead supporting the crosshead by means of an extension to the rear thereof, the said bearing being mounted on the base frame. 3. In extrusion presses, a container for the metal to be extruded, a crosshead disposed to the rear of and supporting the container, a base frame, and a bearing to the rear of the crosshead supporting the croshead and con tainer and mounted on the base frame, the said crosshead being rovided with a rear ward extension secure thereto and mounted in the bearing, 4. In extrusion presses, a container for the 20 metal to be extruded, a crosshead disposed to,
the rear of and supporting the container, a base frame, a bearing to the rear of the crosshead mounted upon' the said base frame, and a mutual upon the said crosshead received 25 into the sai bearing with clearance, and adjustable wed s between saidbearing and said journal or adjustment of the axial disposition of the crosshead and the container so carried by it with reference to the base frame.
