Description

 .one

The invention relates to pipe-bending production, in particular, to devices for two-sided bending of pipes, namely, bends.

A device for bending is known. Water, containing a bending mechanism, consisting of a bending template, and L bending rollers with a drive mounted on the bed Jl J.

However, when bending this device does not ensure uniformity of the thickness of the wall in the place of the bending of the pipe.

A device for two-sided bending on pipe billets is known, comprising a bending mechanism with mandrels and a driven feed mechanism mounted on cTuifflHe.

This device is complicated by design.

shch: it has a large amount when,

water supply mechanism.

The aim of the invention is to eliminate this drawback.

This goal is achieved by the fact that the feeder is implemented in the form of a two-sided tag and interacting with

It is a pusher, as well as kinematically connected with a pusher bracket fixed on the frame, and a grip connected to the drive and not a supporting roller.

FIG. 1 shows the device, a general view; in fig. 2 - the mechanism for feeding the blanks to the source position; in fig. 3 - the same, at the time of the bend.

On the frame of the device 1 there is a bending mechanism consisting of a matrix 2, two bending sectors 3 installed in the carrier 4. In the middle part of the carrier there are guides 5 in which the sliders 6 are moved, the left and right rotary 7, intended for straightening the inside of the billet when it is flexible.

On the bed. 1 also houses a feed mechanism consisting of a frame 8 on which a plate 9 is mounted. A pneumatic junction plate 1O is mounted on a plate, the rod 11 of which is connected to a gripper 12 equipped with an anvilting roller 13. On the same plate 9 a guide 14 is mounted to move a slide block 6 with the right Dorn 7 fixed on it, guide 15 for moving the gripper 12 and the mechanism supporting the workpiece in the upstream position. The mechanism consists of a two-sided ay 16, mounted in a 14 sharfly fixed strut and a stand 17 and a collar with a tsdtkatel 18, which is moved in racks 19 and kinematically connected with a bracket 20 pivotally mounted on the racks 21. The lower position is max. is bound by a delimiter .22. . ,, Kroshltein 20 is provided with a stop 23 to prevent the piston from being linearly inserted while the right mandrel is being fed into it 7. One end of the lever 16 is equipped with a roller 24. The device operates as follows, -. The work feed mechanism is located. c. starting position. The slider 6 acts on the roller 24 of the belt 16, which, with a TEL 18, holds the matte crown .20 in its original layout. ; : The bracket 20 is supplied. A preliminary preheated billet is supplied, the pneumatic cylinder 10 is turned on, and the right one is ... Dorn-7. grip 1.2 - is inserted into the workpiece. find the limiter 22. Then go to the right mandrel along with a pile into a strip limited by matrix 2 and bending sectors 3. After that drove 4 npHBOrisiTcfl into rotation into opposite directions. The bending mounts 3 mounted in SHKNEYCHY are driven around matrix 2 and bend the tubular billet. In this case, the mandrels 7 are mixed synchronously with flexibly) by sectors 3 and thereby prevent the deflection of the wall of the resulting steeply bent outlet. As soon as the bending sectors 3 come off the branch and the mandrels 7 come out of its internal cavity, the removal under the action of its own weight is removed from the bending zone. The reverse is engaged, and the carrier 4 returns to its original position, with the right mandrel 7 engaging with the catch. 12. . , . The pneumosheter 10 and the slider 6 with the right mandrel 7 are mixed in the initial position, and it will act on the roller. 24, rotates the double-shouldered blade 16, moving the pusher 18, which sets the bracket 20 to its original, position ..- -.-..- .. Then the cycle repeats. The design of the device, such as that, which reduces the laboriousness of its manufacture. provides -} reliability of operation. The invention of the device for two-sided bending of bends from tubular billet, which contains features are flexible with mandrels and a feed mechanism with a drive mounted on the tube, such as that for the sake of simplifying the design, the flow is made in the form two shoulders and a pusher in contact with it, as well as a kinem T1kkey connected to the pusher of a bracket pivotally fixed to the stittnie, and a grip connected to the / drive and / bearing. oprny roller.
