Abstract

The invention relates to devices for end rolling. The purpose of the invention is the expansion of technological capabilities by providing rolling with increased specific loads. The device contains work rolls 3 mounted rotatably in support and radial bearing groups housed in housings 2. Bearing support group is made in the form of three support blocks consisting of axes 4 mounted in housings 2 at an angle to the axes of work rolls 3 , two radial rolling bearings 5 placed on the axles, on the outer rings of which the support rollers 6 are pressed in. When the device is in operation, the load on the support blocks is distributed evenly, despite its non-centered application, and this allows Exclude the possibility of jamming, and working with high specific loads. 1 il.

Description

The invention relates to the processing of metals by pressure and can be used in devices for mechanical rolling.

The purpose of the invention is the expansion of technological capabilities by providing rolling with increased specific ⁵ loads.

The drawing shows a device, General view.

On the adapter plate 1 with a beveled surface, there is an upper housing 2 10 and a work roll 3 located therein, equipped with three support blocks consisting of 4 axles with two radial rolling bearings 5 mounted on them, on the outer rings of which ₁₅ support rollers 6 are pressed .

For the perception of radial loads, the shank of the work roll 3 is installed in a radial rolling bearing 7. To perceive the static axial load created by pushing the workpiece in the work roll 3 of the lower housing 2, as well as the weight of the rotating parts in the work roll 3, a thrust bearing 8 is installed in the housing 2.

The work roll 3 of the lower housing 2 is rigidly connected to the sprocket 9 of the gear chain transmission. On the work rolls 3 with the help of the ring 10 and bolt connection 11, a stamp 12 and a punch 13 are mounted. For their fastening on the work roll, radial T-shaped grooves 14 are made.

The cases 2 are attached to the press with bolts (not shown): the upper one - through the adapter plate 1 with a beveled surface, the angle of inclination of which is equal to the angle of inclination of the axis of the work roll 3 of the upper body 2 to the axis of the press, and the lower one is mounted directly on the lower press plate.

The device operates as follows. The deformable workpiece 15 is placed in the stamp 12. The punch 13 by the mechanism for moving the press slide is brought to the stamp 12 until it contacts the workpiece 15. The rotation drive of the work roll of the lower case is turned on and the workpiece is deformed. The press force perceived by the work roll 3 is transmitted to the support blocks. Since the design of the work roll 3 and its fastening to the housing 2 is rigid, the load on the support blocks is distributed evenly, despite its eccentric application. This eliminates the possibility of jamming of the device. Upon completion of the deformation process, the upper case is lifted and the finished part is pushed out by a press ejector (not shown).

The ability of the device to absorb axial load is characterized by the total dynamic load bearing capacity of the bearings installed in the support blocks. The device has dimensions that allow 20 to install it on hydraulic presses with an force equal to the load perceived by the device.
