The invention relates to the processing of metals by pressure, in particular to equipment for the manufacture of articles of flexible bar.

The known automatic line contains a rack installed in the course of the technological process, a device for single delivery of blanks, a receiving roller table, a sorting mechanism, a bending device, blocks of stops of the first and second bends and a block of retractable stops, a device for removing products and receiving finished products 1.

A disadvantage of the known line is that the sorting mechanism does not reject the blanks, which does not guarantee quality products and requires an unproductive screening of products.

The aim of the invention is to improve product quality and productivity.

The goal is achieved by the fact that the automatic line for the production of curved products from rods, mainly half-chain chains, containing a rack with a single piece dispensing bar installed during the process, a sorting mechanism, a drive roller, a bending device and a receiver for finished products are equipped with a bar cutter dimensional workpieces with a conveyor of their reception, placed between the rack and the sorting mechanism, two successively placed above the roller table, catch of the preforms and communication, with associated cassettes for workpieces, wherein the bending device is configured as two bending privodn1h blocks sequentially arranged along a roller table against respective catches with the cassette and the receiving finished products made as a conveyor and placed by the reset pivoting tray.

The sorting mechanism is made in the form of an orienting chute with an adjustable stop located in its lower part and a side swivel and spring-loaded wall, a forked pusher and a hinge-mounted workpiece catcher with a parabolic receiving part.

FIG. 1 schematically shows an automachine line, top view; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section B-B in FIG. 2; in fig. 4 is a section BB in FIG. one; in fig. 5 is a section of YYD in FIG. 3; in fig. 6 is a section d-d in FIG. 3; on. FIG. 7 - receiver of finished products, side view; in fig. 8 is a view E of FIG. 7; in fig. 9 is a cut-out section. FIG. one.

The automatic line includes a rack 1 with a unit for issuing bars, orienting the driver head 2, a device 3 for cutting rods into workpieces of a certain length, a conveyor 4 for receiving workpieces, a sorting device 5 installed between the conveyor 4 and the drive roller 6, drive catchers 7 and a sensor 8 the sequence of submission of the workpieces installed above the rrlgang 6, the bending blocks 9, the receiver 10 of finished products and the conveyors 11. The drive catchers 7 are installed coaxially to the bending blocks 9.

The sorting device 5 includes an orienting chute 12, a forked pusher 13 with a stepper drive, a billet catcher 14 and a slip 15.

In the lower part of the orienting chute 12, an adjustable stop 16 is mounted for movement along the rear wall, the position of which is chosen in such a way as to ensure the retention of the blank 17 along the stop 16 between the stop 16 and the catcher 14 and tilting the non-condi- tional blank on the frame 15.

Lateral wall 18, mounted; Nirno in the lower part of the orienting chute 12, interacts with the spring 19.

The workpiece catcher 14 is mounted on the hinge 20. In the absence of the workpiece, the spring 21 provides a gap between the catcher 14, the workpiece presence sensor 22 and the stop 23 of the movement of the catcher 14.

For automatic installation of the lower end of the standard blank 17 at a specific location of the catcher 14, the surface of its receiving part is made parabolic.

Between the installer 14 and the drive roller conveyor 6 is installed sklez 24.

Coaxially, each bending unit 9 is installed drive catch 7 and cassette 25.

The safety device 7 is equipped with a stepper two-rod drive 26, a contactless sensor for the entry of workpieces 27 and a limit switch 28 for switching on the bending unit 9.

The bending unit 9 contains rollers 29, a fixed conical stop 30, a spring-loaded movable stop 31, a stopper 32 and a corner.

Under the drive roller table 6 installed receiver 10 of the finished product, containing: cracked conveyor 34, rotary tray 35 with drive 36 and the counter 37 of the finished product.

Automatic line works as follows.

Preliminarily, when setting up the line, several blanks 17 are laid in the cassette 25. The first blank under the pressure of the subsequent ones leaves the cassette 25, lands on the rollers 29 of the bending unit 9, pressing the spring-loaded conical stop 31, abuts against the stop 32 and clamps the conical stops 30 and 31 .

After this line is prepared for work.

A bundle of bars is placed on the rack 1, the device for the output of which separates one by one rod and feeds it into the orienting specifying head 2.

An orientation rod is fed into the device 3 up to the stop for cutting on blanks of a given length. Conforming blanks and end waste are fed into the conveyor 4 to receive the blanks and fed to the rejecting device 5 orienting chute 12. em it to the right.

In this case, the upper billet of the workpiece 17 rests on the support 16.

Under the influence of the workpiece 17, the catcher 14 is rotated on the shield 20 to the right, compresses the spring 21 and interacts with the sensor 22 for the presence of the workpiece. The catcher 14 is rotated before contact with the limiter 23, which protects the conditioned billet from falling out.

The sensor 22 for the presence of blanks in the catcher 14 includes a drive shaft forked pusher 13, which the conditional blank 17 moves towards the driven roller table 6, and the upper end of the workpiece 17 deflects the spring-loaded wall 18. The conditional blank falls on the clip 24, which rolls onto the drive roller table 6, and the spring 19 returns the earthy steak 18 to its original position, the closure guiding the section. orienting chute 12.

When a non-conforming billet arrives at the catcher 14, its upper end does not fall on the adjustable stop 16, it tilts on the frame 15, and then into the container 11.

After delivery of the workpiece, either to the belt 24 or to the belt 15, the spring 21 returns the catcher 14 to its original position, turning it on the rail 20 to the left.

When this sensor 22 gives the command to the pusher 13, the drive of which moves the forked pusher 13 to its original position.

The air conditioner billet 17 is fed by the driven grinder 6 to the bending blocks 9 and enters the first driven safety device 7. The contactless billet sensor 27 is activated, and the two-rod drive jig drive 26 moves the safety device 7 with the billet 17 to the flexible side.

block 9. At the same time, the one-sided shaft of the rod with the safety device 27 moves the workpiece 17 to the cassette 25, and the other end of the shaft interacts with the limit switch 28, which includes the bending unit 9. 5 The punch of the bending unit 9, moving the roller, deforms the workpiece on the rollers 29 and pushes the half-formed chain into the frame 33, while the rest of the blanks at the same time are in the cassette 25.

After the bending unit 9 puyona moves upward, the next billet enters from the cassette 25 on the rollers 29 and is fixed in the stops 30 and 31.

Rolling table 6 next

5, the workpiece passes under the driver of the shchagovy drive 26 of the catcher 27 and interacts with the sensor 8 of the order of supplying the workpieces, which commands the drives 26 of the catchers 7. The drives 26 return the catchers 7 to the initial position, and the header is moved by the roller table 6 further to the catcher 7 located coaxially with the second bending unit 9. Further operations with the workpiece are carried out as described. Half of the chains of the bending blocks 9

5 is transferred to the conveyor 34 of the receiver 10. of the finished product, transported by it under the counter 37 of the finished product to the rotary chute 35, through which it enters the coyteyer, 11. When one container 11 is filled, the counter 37 issues a command to the drive 36, which trays 35 are turned towards the second coitter I.

When any flex block 9 is shut down for a short time, incoming billets accumulate in the corresponding cassette 25 and the operation of the laser does not stop.

5 The presence of driven blanks, an automatic communication sensor system, billet storage bins and a receiving device made in the form of a conveyor with a swivel tray, extends

The technological capabilities of the line, as it allows to combine different in performance bending device and cutting device, as well as to make short-term repairs to the bending devices without stopping Li.

5 The sorting device increases the durability of the traction chains by 30-50%, as it prevents the production of correct semi-links or semi-branches with a distorted configuration, which is obtained by bending non-measured blanks.
