SU86474A1 - Profile bending machine - Google Patents

Description

Machines are known for bending a profile material fixed at one end on a rotating cam and pressed against a copier by a punch.

The proposed machine differs from the known ones in that in order to bend the material in several planes, the holder for the punch is rotatably installed around its axis and movably along a straight, perpendicular to this axis.

FIG. 1 shows a schematic front view of a machine; in fig. 2- replaceable copier, cut; in fig. 3-working head, front view; in fig. 4-working head in section according to AA in FIG. 3; in fig. 5 punch, top view; in FIG. 6 punch, section along BB in FIG. five; in fig. 7 and 8-shape of a PHONE bent in two planes.

On the carriage of the lathe mounted pneumatic cylinder / (Fig. 1). Between him and the front headstock 2 of the machine is mounted a round table 3 with a separate drive from the electric motor. Replaceable copiers 4 (Fig. 2) are rigidly fixed on the table. The roller 5 (Fig. 1) mounted on a stand 6 prevents the table from bending under the pressure of the punch. At the end of the cylinder rod 7 / the working head is rigidly fixed (Figs. 3 and 4), consisting of a support 8, a slide 9 and a punch holder 10 -. The slider 9 is moved along the guides of the dovetail in the vertical direction, and the -10 hinge holder is attached to the slider.

The punch (Fig. 6 and 6) is fastened in the holder 10 by means of an axis; passed through the holes in the ears and the pch anson and holder The punch consists of a body y and a pivot bar 12 hinged in it. The distance between the interchangeable bars 13 is assumed to be equal to the height of the profile.

At the end of the bend profile, the holes are drilled and, with their help, they fix this end on the interchangeable cam 4. Then the table is brought 3 N

copier 4 in rotation. After turning on the cylinder / punch, pressing the profile to the copier, bending it according to the shape of the copier.

If the profile needs to be bent in two planes (Figs. 7 and 8), then an interchangeable height copying copier is used. The punch pressed against the material and the copier, when the height of the copier is changed, moves up and down, all the time remaining against the copier. Such an interchange 1 is possible due to the fact that the holder 10 of the punch is mounted, as it would be. Above, movable along a straight, perpendicular to its axis.

Installing the holder pivotally around its axis allows the profile to bend in a third plane (around its axis), corresponding to the shape of a replaceable copier.

To change the shape (ma; 1k15kp) of the profile, for example, bending one shelf at an acute angle, use a rotary shoe 12, self-aligning with iodine at the same angle as the copier profile in this area. Block 12. Can only be under the action of a copier or at one time a copier and a pneumatic cylinder.

A second (vertical) working head 15 can be mounted on the beam fixed on the headstock 2 and tailstock 14, which is used to bend the profiles only in one plane around an axis parallel to the flanges of the profiles, according to KOinipy, mounted on the table 5 instead of round copier 4.

PRIOR DIRECTORSHIP and

Claims (2)

1. A machine for bending profi.pnogo material by puapson, pressed to the material, reinforced end on a rotated from the drive of the copier, from l and chu ni. and with the fact that, in order to bend material in several planes along an appropriately shaped copier, the punch holder is set to rotate around its axis and move along a straight line perpendicular to this axis. 2. The form of the machine according to claim 1, characterized in that for changing the shape of the profile during bending, the punch has a swivel block located under de | | copy only copier or copier and pneumatic cylinder.
