Description

one

The invention relates to the treatment of meta-hrs by pressure, in particular, to mechanical rotary pressing.

A device for rotary extrusion of parts of cylindrical and conical shapes is known, comprising a front headstock mounted on an-stand with a driving mandrel, a cage with a deforming tool and a rear 10 headstock with a receiving tray l.

A disadvantage of the known device is the lack of automation in the loading of finished products. .

To increase the productivity of j by automating the unloading of finished products, the device is equipped with the unloading mechanism and receiving table, while the unloading mechanism is made

in the form of a power cylinder mounted on the tailstock with the possibility of interaction of its stem by means of a fork with a swivel axis placed in the central bore of the receiving tray and carrying levers into the slots of the receiving tray. .id base .. with grooves, plate q combs, interoperable with the additional shaft of the cylinder strength, mountedJQ

on the base, the fixed plate and, intermediate sklizy, one of which is fixed on the tailstock, and the other - on the fixed plate.

a .fig 1 shows the proposed device, a general view; in fig. 2 is a view along arrow A in FIG. in fig. E view along arrow B in Fig.2; in fig. 4B-B in FIG.

 The device consists of a bed 1 on which the front has been mounted, the headstock 2 with the driving mandrel 3, the stand 4 with the deforming tool and the back headstock 5. with the receiving tray 6. In addition, the stand 1 cylinders 7 with the stop bars B. are mounted on the stand 4 The power cylinder 9 of the unloading mechanism is mounted on the tailstock 5, and its rod 10 is connected by a finger 11 to a fork 12. A swivel axis 13, an pin 14 with a fork 12, is placed in the central bore 15 of the receiving b, on which the 16 are mounted with pins 16 levers 17 located in the slots of the receiver Single 6 interim slide-ways 18 fixed to the tailstock 5.

The receiving table 19 is made in the form of a base 20 with grooves for placement

finished products 21 and circular guides 22 along which the plate 23 moves with combs 24 reinforced with rubber 25 to protect it from

damage to the outer surface of the finished products. Plate 23, having sleeves 26, is connected by a pin 27 with a current 28 of an additional power cylinder 29 and serves to lower the finished products from a treatment height to a height convenient for subsequent transfer to vehicles. The fixed plate 30 is fixed to the guides with 22 nuts 31. On the fixed plate 30, the intermediate frame 32 and the adjusting bolts 33 are attached, which serve to limit

stroke plate 23. On the tailstock 5 is also mounted quill 34 with center 35.

The operation of the device is as follows.

At the end of the rotational extrusion process, the quill 34 with the center 35 serving to support the cantilever end of the mandrel 3 is retracted and the back headstock 5 is displaced in the transverse direction so that the axis of the receiving tray b is aligned with the axis of the mandrel; 3 Then, the rods with retaining L-joints B are reduced in the radial direction (to the axis of the mandrel) and during the return stroke of the cage 4 (to the tailstock)

interact with the end face of the finished product 21, remove it from the mandrel 3 to the receiving tray b, which is at the same time on the same axis as the mandrel 3. When the stand 4 reaches its initial position, the rods of the power cylinders 7 are separated in the radial direction (from the axis of the mandrel 3) ; In this case, the movable plate 23 with the combs 24 is in the upper position. To reset the finished product 21 from the receiving tray b, the stem 10 of the power tynd; the mechanism of the unloading mechanism is pinched and rotates the fork 12. Since the vial 12 is connected to the rotary axis 13, it is rotated and the levers 17 mounted on it interact with the ready product 21, push it out of the receiving tray 6. The finished product under. with its own weight along the inclined plane formed by the slits 18 and 32, rolls onto the comb 24. When the rod 28 of the additional power cylinder 29 is moved downward, the plate 23 connected to it with the grooves 24 and located on them the finished product 21 also moves downwards, with This 5 combs 24 passes through the grooves of the base 20 of the receiving table 19 until the finished product gets on the inclined support surface of the base 20 and does not roll under its own weight. Next, the finished product 21 is automatically transmitted to the vehicles (not shown in Fig.). Then the plate 23 with the combs 24 is moved upwards and remains; at

This position until the next unloading of the finished product 21. The above described operation cycle of the device is automatically repeated.
