WITH

The invention relates to the mechanization of stamping production and can be used to automatically feed piece pieces into dies. The aim of the invention is to expand the technological capabilities of the device due to the orientation of the blanks relative to the die of the stamp during the movement of the blank to this stream. Fig. 1 shows a kinematic diagram of a device for supplying piece blanks to a stamp with its binding to the kinematic scheme of a device for die-casting in separable dies on a press; figure 2 is the same, a partial longitudinal section; FIG. 3 is a view A of FIG. 2; in fig. 4 - section bb in figure 2; in fig. 5 is a view In figure 2; on fig.6rez GG on fig.Z; figure 7 section dD in figure 2. The device for feeding the piece blanks into the stamp contains a support 1, which is attached to the table 2 of the press, bracket 3 is attached to the support 1, the power cylinder 4 is mounted on the bracket 3 with the rod 5, to which the gripping member 6 is attached. The guide rod 7 is enclosed by a hollow rolling pin 8, which is connected to the gripping member 6. The guide shoe 7 and the hollow rolling pin 8 prevents the gripping member from rotating during its reciprocating movement. Gripping body including body 9 with guides 10 and sub-40

 dodeine spring 11 stop 12,

In the upper part of the crush line 3, a magazine 13 is mounted under the workpiece 14. A movable stop 16 with petals 17 is mounted on cheeks 15. drive, v, e. the power cylinder 4, on the bracket mounted auxiliary drive. The auxiliary drive contains a power cylinder 20 attached to the rack 21 of the crown 3, the rod 22 of the power cylinder is provided with a frame 23, which is mounted on the guide rods 24 fixed in the rack 21, moves to the axis of the press, t. e. according to the drawing to the right. Billet from falling all the way out of the nest

held by blocking the latter by an abutment 12. When the abutment 12 touches the punch, it stops, and the gripping device 6 continues to move to the axis

press. Spring 11 is compressed and petal 42 due to its entry into the slot of the limit switch gives the command to stop the gripping organ. The window of the gripping organ is released from the abutment 12 and the blank 14; delivers to the engraving the lower fixed semi-matrix 30. After releasing the gripping organ from the billet, the piston- VIE stock 22. With movable stop 16 of magazine 13, a pusher 25 is mounted on the frame, the upper sub-plate 26 of the device for manufacturing articles by columns 27, passed through the lower fixed plate 28 of the same device, is connected by means of the mechanism 29 of lower movable shaft 28, position 30 conventionally marked lower fixed semi-matrix, and the position 31 upper movable semi-matrix. The lower 32 and upper 33 ejector pushers driven by power cylinders 34 and 35, respectively, can pass through the central hole of the semi-matrix. The drawing also shows cylinders 36 - 38 of the semi-matrix clamping mechanism, part 39 after installing it in the die, limit switches 40 and 41, their petals, respectively, 42 and 43. Cylinder 4 has rod 44 and piston 45 cavity, power cylinder 20 - rod 46 and piston 47 cavity. Device for feeding piece blanks works as follows. In the initial position, the gripping device 6 of the device is outside the semi-matrix 30 and 31, which is closed between them. That is, the device is moved by the rod 5 of the power cylinder 4 according to the drawing to the left and in this case is located under the magazine 13 for the workpieces. - 38 through the system of levers (not indicated) of the column 27 of the upper movable plate 26 B, cavity 45 is supplied with energy carrier, under the action of which the rod 5 together with the gripping body the non-cavity cavity 45 of cylinder 4 is connected with the atmosphere, and the rod cavity 44 is connected with energy carrier. The gripping member 6 with the stem 5 moves (according to the drawing to the left) in the direction from the axis of the press. When the gripping body leaves the stamping area outside the press, the upper movable plate 26 is lowered with the help of cylinders 36-38 and clamped with the lower fixed plate 28, thereby closing the half-matrix 30 and 31. After closing the semi-matrix the press makes a working stroke by moving through the levers of the working horizontal punches of the device (not shown), before making a technological operation for the manufacture of the product, the shop 13 mechanized means of mechanization (not shown) is fed The forging 14. When the billet reaches 14 of the bottom of the magazine 13, energy carrier is supplied to the piston cavity 47 of the cylinder 20, and the rod cavity is connected to the atmosphere (drain) at this time. The rod 22 with the pusher 25, moving forward,. pressure on the upper end of the workpiece 14, which, interacting with the movable stop 16, deflects it, and with it, the petal 17. fixed in it deflects. The blank lies between the cheeks 15 of the magazine 13 into the slot of the gripping member 6. entering the slot of the end switch 18, closes the circuit and sends a command through the distributor to supply energy to the rod 46 of the power piston 20 and to connect its piston cavity 47 with the atmosphere (drain. The pusher 25 with the rod 22 is output from the cavity 13 and last The next heated billet 14 is fed. After the technological operation is completed, the upper movable plate 26 of the die forging die, together with the upper movable semi-matrix 31, is lifted upward by means of cylinders 36-38. the energy carrier, and its rod cavity 44 is connected with the atmosphere (drain. Under the action of the energy carrier, the rod 5 with the gripping body 6 and the workpiece 14 is again moved to the axis of the press. When the NII is closer to the axis of the matrix engraving, the I2 stop is pressed to the left, the slot in the gripping body is released and the workpiece passes into the last one when the slot of the gripping body is aligned with the matrix engraving. At the same time, the accuracy of the orientation of the workpiece is provided by the cheeks 15 and a slit in the gripping body 6, which is strictly precisely located above the engraving of the lower fixed semi-matrix. After the workpiece 39 is installed, the piston cavity 45 is connected to the atmosphere and the energy carrier is supplied to the rod cavity. When the gripping body reaches its extreme position of the press axis, the cavity 47 is connected to the source of energy carrier, and the cavity 46 is connected to the atmosphere. The workpiece 14 is pushed by the pusher between the cheeks 15 and further into the slot of the gripping organ. The cycle is repeated. The limit switch 40.41 and 18 with its lobes 42, 43 and 17 control and block the operation of the mechanisms of the device with each other with the device and the press for the manufacture of products in closed matrices.
