concerning
Device for manufacturing bearing shells

The innovation relates to devices for molding or production of bearing shells from a flat strip of material and the task of the innovation is to create a simple device with the precisely shaped bearing shells can be produced at a high production speed.

The device according to the innovation is marked by a bed with a channel for receiving the flat Material strip, a pusher for advancing the material strip and a rotatably supported at the end of the bed Role,; from which a rope of the cylindrical circumferential surface together with a concave hat curved around the same axis on a stationary component, one adjoining the channel curved channel of jsiner the thickness of the strip of material corresponding eye depth with the desired radius of curvature Bearing shell limited.

With the device after hiring storage shells are shaped in such a way that a strip of material is introduced into the channel provided in the bed -and then is pushed through the curved channel by the slide with the application of force.

It has been shown that the manufacture of camp soles with this new device is considerably easier than with the devices known up to now, in which Iiagerschalen are made with the help of a die that

the
with a curvature of the bearing shell corresponding recess

is provided.

The device according to the innovation can in particular then apply when the bearing shells are formed one after the other from individual flat strips, but it is also possible to use the Device with the characteristics of the furnace to be used if the Iiagerschalen are made of a coherent strip of material of greater] recently, whereby they then however, it must be combined with a cutting device. The device can also be learned according to the wage Apply well in the manufacture of storage shells that only a part of a cylinder or a complete cylinder form.

Further advantageous details of the device according to the innovation result from 'the following Description of an exemplary embodiment used to explain the firing.

1 is a side view, partially drawn as a section along line 1-1 in "I ¹ Ig. 2, of a device according to the invention for forming a bearing shell, with a bearing shell that has only been partially formed being shown.

Fig. 2 is a section drawn on a larger scale along the line H-II in FIG. 1.

lie device comprises a bed IT, which at its top has a hat 12, along which the strip of material 13 » from which a bearing shell is to be formed, in the longitudinal direction can slide if on the strip of materialjta.it help a reciprocating slide or pressure piece 14 a thrust is applied.

B- ^ e Fut or the channel 12 leads the material strip into a channel extending from the peripheral surface of a roller 15 and a concave curved surface 16 on a stationary part at the end of the bed 11 which serves to J-shape the material is limited. The surface 16 has the same radius of curvature like the should 15 »which rotates around its main axis, and the

Space between the I plane 16 ″ and the aula 15 just gnawed around the one which has a certain thickness Material strips 13 take up.

Shortly before the should 15 see a cross piece Λ7 on the hat 12, which holds the strip of material in its flat shape until the point in time in which the Material is curved. Below the lut 12 is a narrower slot 18 is provided in which the printing block or the slide I4 is slidably mounted.

It has been shown that when the material strip 13 is subjected to force in alignment with its longitudinal axis is pushed into the curved canal, it is possible to use a part of a

.Shell, e.g. a bearing shell, or a complete one To give the cylinder-forming shell exactly the desired shape, wenii-the device described is used with the Bolle 15; ■ in. Fig *. 1 is shown at 19 a partially formed bearing shell. "; ■ ■"

A bearing shell that extends over less than 180 ° can easily be removed from the Bolle 15; a bearing shell forming a complete cylinder can in the I ¹ Ig. 2 evident way from the. Bolle 15 to be stripped; in 'Fig. 2list to recognize that the. two bearing shells 21 and 22, which were formed in front of the bearing shell 19, Cheeks "share 24 held; the cheek parts 24 are connected to the side surfaces of the bed 11 by screws and determine the position of the holes of the bolls 15. The outer end of the second bearing shell 21 rests against the inner end of the first bearing shell 22, and it is partially supported by the Bore 23 and the other part supported by the Bolle 15 , so that this bearing shell acts as a La, ger for the free end of the Bolle 15.

. The bolt 15 is shown in FIGS. 1 and 2 on a hollow pin 26. supported by a flange with the outside the left cheek part 24 is connected, while the: free end of the journal 26 is only held in its position by that .the free end of the Bolle .15 through the previously formed bearing shell 21 is supported by the hole 23 in their Location is held. ■ ■ ■:

Fachdem the warehouse 19 has been completed, will ^! one in S ¹ Ig. 2 by the arrow 27 indicated piston or the like. Printed against the left end of a rod 28, which is slidably mounted in the hollow bearing pin 26 and by a. Helical spring. 29 is biased outwards. A plate 31 is firmly connected to the rod 28, in which three rods 32 are installed, which extend through bores in the left cheek part 24 and at their free ends carry an annular ejector 33 within which the bolt 15 is slidably mounted. When the rod 28 is pushed to the right as shown in FIG. The bearing shell in turn pushes the bearing shell 22 in front of it so that the bearing shell 22 falls out of the device, as indicated in FIG. 27; the finished bearing shells are fed to a collecting container in this way. The compression spring 29 then returns the rod 28 to its starting position, whereupon; the door direction is ready for the production of the next bearing shell. From Fig. 1 it can be seen that in practice the ejector 33 does not form a complete or closed inlet so that it does not hit the bed 11 when it is advanced.
