Description

The invention relates to the processing of metals by pressure, in particular to the means of automation during stamping.

The purpose of the invention is povedeniya device performance.

FIG. 1 shows a kinematic diagram of a device for feeding blanks into a working area of a processing machine; in fig. 2 is a sectional view in FIG. one; in fig. 3 - feeding slides and transporting trays, section along axis.

The device / contains a feed skim 1, in which two workpieces 2 and 3, the top 4 and the bottom 5 gates, located on the same axis with the feed skirt 1 and having cut-off devices 6 and 7, are supplied from a heating device (not shown). the tray 8 for rejected blanks, the receiving end of which is located on the same axis and in the working position is covered with a supporting platform 9 and connected to the power cylinder O with the aid of. lever 11, the drive mechanism. the upper 4 and lower 5 gates, consisting of double-arm levers 12 and 13, connected by means of grams 14 and 15 and a short box 16 with a power cylinder 17, transporting trays 18 and 19, made in the form of bent pipes and located on both sides of axes of the feeder slip 1 so that when turning

double-arm levers 12 and 13, the axis of the upper 35 towards the working positions of the gate valve 4 coincides with the upper end of the transporting tray 19, and the HicKHero axis of the gate 5, with the upper end of the transporting tray 18, orienting the jaws 20 connected to the power cylinder 21 by means of a common shaft 22 and t g 23, rotary platforms 24, mounted on a common shaft 25 and. held in a horizontal position by the pneumatic stem 26 and the photo head 27, registering the presence of the workpiece 3 on the supporting platform 9.

The protractor grips 28 | (its devices (not shown) have the possibility of gripping - blanks 2 and 3 for the lower part between the reference point of the jaws 20 and the rotary platforms 24.

The device works as follows.

In the feed slip 1, two blanks 2 and 3, heated to the forging temperature, simultaneously arrive in the upper 4 and lower 5 gates and abut

c. to the support platform 9. The photo head 27, illuminated, gives a signal to the control system (not shown), and the power cylinder 17 through the beam 16 and the hinges 14 and 15 rotate the two shoulders levers 12 and 13. The workpiece 3 begins to slide along the support platform 9, -a workpiece 2 slides over the end face of the workpiece 3, and then along the extractor 7, the cut-off 6 at this time overlaps the inlay in order to avoid accidental ingress into the third preparation device. Further, the upper gate 4 together with the workpiece 2 takes up a position above the upper end of the transporting tray 19, and the lower gate 5 together with the workpiece 3 takes up a position above the upper end of the transport tray of the tray 18. Workpieces 2 and 3 fall down and pass through the transporting trays 1B and 19, they are placed on the turning pads 24 and are held in the orienting mechanism by means of the orienting jaws 20. The grips 28 of the transport device capture the workpieces 2 and 3, and at this moment the command is issued to open the orienting jaws 20. Power second cylinder 21, rotating the shaft 22 by means of rods

opens the orienting jaws 20. Simultaneously with the opening motion of the jaws 20, the grippers 28 of the conveying device with the gripped blanks 2 and 3 begin to move

batyvak day machine.

After the release of the orienting mechanisms, the command is given to reverse the actuation of the cylinders 21 and 17.. The device is brought to its original position. When billets that have not reached the required temperature, or a short-term stop of the processing machine, the control system sends the command to trigger the power tsipindra 10, which with the help of the lever 11 rotates the bearing platform 9. In this case, the feed sleeve 1 passes the upper 4 and lower 5 gates and enters tray 8 for rejected blanks.

At an emergency stop of the processing small at the moment when the workpieces 2 and 3 were already on the rotary areas

24, the control system supplies to the platform 24 in a vertical position, the mandrel for the operation of the pneumatic cylinder Billets 2 and 3 fall through 26, which turns the rotary away from the press.
