Description

The invention relates to wavelength equipment, and is intended for the manufacture of shaped profiles.

A multi-wheel caliber stand design is known, comprising an annular bed, a cassette with work rolls (rollers), and a device for synchronous radial roll mounting ().

However, such a stand in the transition to rolling (drawing) of the subsequent rebellion of the workpiece requires re-adjustment of the rolls (rollers) to the specified size of the output profile.

In the proposed roller head, this drawback is eliminated due to the fact that the cassette is made movable along the axis of drawing relative to the housing and is provided with an axial displacement drive in the form of an annular hydraulic cylinder, and the inner surfaces of the pressure wedges are made in the form of copiers, on which the outer bearing supports of the rollers are opened.

FIG. 1 but a cauldron is offered a roller head; in fig. 2 is a view along arrow A in FIG. one.

The ryulik head contains vertical 1 and horizontal 2 rollers fixed on axles 3, on the necks of which it is pressed; 4 bearings 4. The outer clips are hemmed with 4 pa-sets. They are not fit in 5 and can be freely turned in them. The cushions are inserted into the radial grooves of the cassette 6 and the balancing springs on the 7 are pushed away from the axis of the lug, providing a constant pressure on the outer sleeves of the bearings 4 to the pressure plates 8. The slats 8 are fixed on the tides of the ring body 9 in which the cassette 6 is fastened with locking grooves on the tides of the annular body 9, into which the cassette 6 is attached. strips 8 n internal

the surface of the tides of the housing 9 is made on the wedge. The inner surfaces of the slats 5 are made in the form of copiers, parallel to the 3x axis of the drawing, and partially in the form of wedges, starting at the ends of the strips facing the

the back cover 10. To the opposite end of the slats 8 by the mechanism // of the movement of the slats are attached gi. The screws of the mechanisms //, which move the gi, are fastened in the front cover 12, in which the round ones are also fixed.

guides 13. The cover serves at the same time as a stop for the cassette 6. 11a: Anvil 13 prevents the rotation of the cassette 6 around the axis. The end of the cassette is attached to the hollow rod 14 of the annular G1iarokili1idra 15, which with its back cover is attached to the lid 10. Behind the ends of the strips 8 in the housing 9 are windows through which you can insert or remove the rollers / .2 assembled with the OSMMI bearing. 4 and pillows 5.

The cylinder cylinder 15 cassette 6 is installed against the windows of the housing 9. Rollers 7 and 2 are assembled into the cassettes of the cassette with the AELCI 3, bearings 4 and cushions 5. For p, redo {rotate self-spontaneously falling cushions 5 out of the cassette's sleeves 6, in the latter spring clamps are provided (not shown in the drawing), which do not prevent the latter from approaching the roller O | B.

The hydraulic cylinder 15 of the cussette 6 is mixed forward in the direction of the movement of the workpiece while dragging against the stop into the cover 12. Between the rollers, through the hole in the cover 2, they enter, based on: at the opening, a set gauge.

With the aid of the mechanism, the mechanism // and the strip 5 bring together first the vertical rollers 7 before landing on the caliber, and then the horizontal rollers 2 - until they stop at the vertical ends. The mixing of the strips 8, and consequently, the rollers / and 2, is controlled by the setting scales (not shown in the drawing) entering the mechanism (M 11. When being adjusted, they are preliminarily clamped, the amount of which is then adjusted by test drawing .

After the cassette 6 has been installed with the ram of the hydraulic cylinder 15, it is set to an over / edit position, in which the outer race of the bearings 4 will be opposite the wedge portion of the inner porter rail 8 and the rollers will disengage from the spring 7, forming a passage for the workpiece.

The workpiece is set through a roller head, and with the beginning of the movement of the workpiece in order to drag the cylinder 15 moves the cartridge 6 up to the stop in the cover 12. During this movement

kaosets outer sleeves of bearings 4 are rotated along the inner surfaces of the strips 8 and axis 3; Consequently, the rollers / and 2 move closer to the setting position, deforming the bale. When you stop the cassette 6 at the cover 12 of the roller die begins to go ready strip.

To go to the dragging of the subsequent rebellion of the workpiece, you need tape 6 again

set to the refueling position, set the workpiece, start it again and pull the cassette 6 back up to the lid 12 again. Setting the rollers to the previous size is not disturbed.

Subject invention

Roller head for drawing shaped profiles containing a pair of vertical and a pair of horizontal rollers mounted by their cores. MI in support bearings mounted in a common cassette housed in ring rings and wedge pressure and spring balancing mechanisms, characterized in that warning of re-adjustment of the rollers to the given size of the caliber, three transitions to the dragging BUT)

movable along the axis of the drag relative to the housing and provided with an axial displacement drive in the form of an annular hydraulic cylinder, and the inner surfaces of the pressure wedges are made in the form of copiers, on which the outer sleeves of the roller bearings are supported.
