Description

one

The invention relates to the field of pipe production by rolling.

The known device for transverse tube calcination includes a working stand moved along the guides of the bed, in the cabinet of which the rolls with the mechanism of the machine are installed, and a non-displacing axial non-displacement of the stand. The cage is connected with the drive: and is rigidly rigid and does not allow the possibility of swimming.

In order to facilitate the self-improvement of the stand, it is necessary to improve the production of the machine. The pipe stand of the proposed device is designed to interact with the bed guides of the load bearing box in a vertical plane and with rolling bearings floating in horizontal silt, and the connection of the plug with a porsche drive through floating oiors.

FIG. 1 shows the described device, a plan view; in fig. 2 shows a section along A-A and a and FIG. one; on .fig. 3 is a section along BB in FIG. one; in fig. 4 shows a section along the line Bb of FIG. 2

The device includes a working cage, in a rigid closed case (of which there are 2 rolls (the number of which can be any) with a mechanical radius of the installation). Cage with; 1a bzhena interacting with the CYL: indIrically 1M. And a pair of 4 bed supports supporting, made in the form of: a profile roller 5, planted through a razno; yuzhee -No-screw screw in seiaratore 6 rolling bodies 7 axle axle 8, mounted with the aid of rations 9 into the bore. A movable holder 10, with a shank // inserted into the hole of the nut 12, and with shoulders 13 abutted into the springs 1. fixed in the case of the croppteype stand 15, and by applying the axial movement of the stand in the form of a cilipdro. 16, the rods 17 of which are fixed in the fixed rear rack and the headstock. The cylinder is connected to a cage with a .new.a vayup1uyu support, which represents a rigidly connected support ring 18 and an outer ring 19 and an intermediate ring, and a ring 20 placed between the bottom of the cylinder body and placed between the two yes tel rolling 21 with separators 22.

The device works in the following manner.

The cage assembled by roller 5 is placed on the guides 4 beds perpendicular to the axis 0: Right | KI, the rods 17 of the cylinders 16 are fastened axially and shifted. in the rear rack and the headstock, then adjust the rolls 2 to the desired clearance on the otishe. to the oHp.aiBKe fur-iizamp 3.

With THIS.M two options are possible: rolling smooth tubes and stepped ones.

Then, the drive is switched on: belt cages and transverse rolling of the tube.

At the same time, the center of the ad. Vibra is easily compatible with the yuprashi axis, since the rings 18 and J9 connected to the KOipinycoM / cage are installed with a clearance across the iK ratio to the cylinder body 16, and the intermediate ring 20 can move in the flatness, ; ukul. pivot axis of the mandrel. OnoipH hull cages along the 4 stan- ding lines, are: IB, within certain limits, move the cages like k in the horizontal plane (due to the displaced eccentric axis 8 along the “Acheni 7 relative to the roll 5”), so: vertical nlookosti (due to greater or less compression impyZHIN 14).

Device for cross-rolling tubes

There are plots in the carp, which is a swarm of rollers with mech-eared; they are (happy to install, and the piston drive of the axial movement of the cage, characterized in that, in order to facilitate self-detachment.

working stand on the mandrel, sn, a: bzhena interact. modifying: i1M and with direction. The strut of the bed is spring-loaded: in the vertical plane and floating in the horizontal flat supports of the scaffold, and the connection of the cage with the p-shnevy drive is made through the floating supports. - A5
