Description

(54) PRESS FOR ROLLING OUT OF SHUTTERS

one

The invention relates to the processing of metals by pressure, in particular to presses for rolling shells.

According to the main author. St. No. 567532 is known a press for rolling shells containing a C-shaped vertical frame with a stand, upper and lower traverse mounted on the upper traverse striker, the vertical axis of which is located in the plane of symmetry of the frame, drive the working movement of the striker, removable mandrel mounted on the lower the traverse, the mandrel axis being perpendicular to the plane of symmetry of the bed, and in the stand of the bed in the area where the mandrel is located, an opening is made symmetrical about the plane of symmetry of the bed passing through the bottom Traverse 1.

The disadvantage of the known press is the low quality of the finished product and performance.

The purpose of the invention is to improve the quality of the finished product and its performance by correcting the ovality of the shells.

This goal is achieved by the fact that the press for rolling shells containing

C-shaped frame of the vertical type, having a stand, upper and lower traverse, mounted on the upper traverse firing pin, the vertical axis of which is located in the plane of symmetry of the bed, drive

5 of the working movement of the striker and a removable mandrel mounted on the lower traverse, the mandrel axis being perpendicular to the symmetry plane of the bed, and in the stand of the bed in the area of the mandrel placement

10, the opening symmetrical with respect to the plane of symmetry of the frame passing through the lower traverse is provided with an additional lower traverse rigidly connected to the frame of the press and mounted on it with the possibility of reciprocating

 transfer to the working area of the press with a table fixed on it an additional support.

FIG. 1 shows the proposed press, front view; in fig. 2 - section AA

20 of FIG. one.

The press for rolling shells consists of a C-shaped bed 1, on the upper traverse of which tool 2 is placed with a hydraulic actuator 3. On the lower traverse of a Q-shaped

The frame is installed mandrel 4 on the support 5. The mandrel is equipped with a drive 6 of the rotational movement. Under the lower traverse of the C-shaped bed, an additional traverse 7 is horizontally installed, connected to the C-shaped bed by means of fixed columns 8 and 9 through spacers 10 and I. On the additional traverse there is a table 12 with the possibility of reciprocating movement along the traverse 7 to the working area press, perpendicular to the axis of the mandrel 4, by means of the drive 13. On the table there is an additional support 14 for the shell 15. Repair of the defects of the shell on the press is performed in the following sequence.

The rolled shell, having an ovality, is rotated with the help of the mandrel 4 and the actuator 6 so that the larger diameter of the oval is placed in a vertical plane passing through the axis of the mandrel 4. Then the shell together with the mandrel is lifted with the help of a crane and the table 12 is moved by the actuator 13 into extreme left position (Fig. 2).

Then, the shell 15 is lowered onto the additional support 14, and the mandrel 4 - onto the support 5. The tool 2 is used to straighten the shell.

The advantage of the proposed press for rolling shell compared with that from; / ХЙ9; BUT

It is well known that its technological capabilities are broadened, the productivity and quality of the shell are increased, since shells can be edited. In addition, forge-and-press works on the table are possible; additional traverse of the press with an increased open height of the press (for example, rotation of the shell on the rollers mounted on the lower table when extracting the nozzles).
