Abstract

The invention relates to the cold treatment of metals by pressure and can be used to feed piece blanks into the working area of a stamp and remove finished parts. The aim of the invention is to increase reliability in operation. For this, the device is equipped with a sensor. The sensor regulates the presence of the workpiece in the working area of the stamp and generates signals to enable or disable the stroke of the press. The hydraulic system provides consistent mixing of the slide pusher, the pusher to remove workpieces, as well as the movement of the movable plate. 1 il.

The invention relates to the cold treatment of metals by pressure and can be used to feed piece blanks into the working area of the tamper and to remove finished parts.

The purpose of the invention is the reliability of the work.

The drawing shows a device for feeding 1lt blanks into the working area and removing finished parts.

The device contains a power cylinder 1, a blue cylinder 2, installed on the lower fixed nlit 3 strains, power; 1-core 4 fixed to the direction | Tsei, made in the form of handles, its tray 5, rigidly connected to the plate 3, the pusher 6, which is rigidly connected to the piston 7 of the power cylinder 2. Part 7 is at the spring 8.

The device also contains a 1nibert t (X1, carrying iO and mounted on the piston 1 1 of the power cylinder 4. G1or1nen 11 is spring loaded 12. The magazine 13 and the sensor 14 are fixed on the guide chute 5. In the case of the power cylinder 1 time springs 15 and 16 and iiopHjeHb 17 with rod 18.

The rod 18 is connected to the housing 20 by means of a ball bearing 19. The housing 20 is fixed by means of a lock nut 21 and a screw 22 in the movable plate 23 of the stamp. A punch 24 is fastened on the plate 23, and a NiaTpHua 25 is installed on the plate 3 with a puller 26. The plenum of the power cylinder I is connected by a pipe 27 to the overhead shaft of the power cylinder 2. of the rod of the force cylinder 1 is connected by a pipe 28 to a piston cylinder. 4. In the store 13 is placed a stack of flat puff billet 29. The position 30 denotes parts, the position 31 denotes waste. On the matrix 25, a slide 32 is made to remove the parts 30 from the die working area. The pusher is connected with the rod 33, the piston 7 fixed by the piston, the gate pusher 9 is connected with the rod 34 attached to the nopHjpe 1 1.

The device works as follows.

When moving the movable 1K) plate 23 of the strain up through the housing 20, the ball bearing 19, a force acts on the piston 17, which, moving upwards, compresses the spring 16 and expands the spring 15. The fluid (or air) flows from the actuator 2 into the main power cylinder 1 through the pipeline 27. The piston 7 of the node by the action of the spring 8 and due to the flow of fluid moves to the right and there is no pusher 6 behind it. In the same movement, the porn 17 upward fluid is pushed out of the die cavity of the main power cylinder 1 28 into the power cylinder 4, compressing the spring 12 and the piston 11 with the shifter 9, which acts on the lower workpiece 29 in the stack of workpieces located in the magazine 13 n moves this workpiece, and through it the other workpieces that are tray 5, right on the schag. As a result, the rightmost preform enters the punch working area, and the finished part 30 under the influence of this preform is removed from the plow working area along the slide 32.

The stop 10, mixed, and together with the pusher 9, acts at the end of the turn, i.e., when the workpiece has already reached the working area of the stamp, and the part is from this zone, on the sensor 14, which turns on the press on the reverse stroke (not shown ).

When moving the movable plate 23 of the stamp down again through the housing 20, the ball bearing 19, a force acts on the piston 17, which, having moved downward, compresses the spring 15 and loosens the spring 16. In this case, the liquid flows from the power cylinder 4 to the power cylinder 1 but the pipeline 28. The pistol 11 is affected by the spring 12 and due to the flow of fluid is mixed-left and there is no pusher 9 behind it, and from the shop 13 node the force of gravity flows into the guide tray 5 the next billet. During the same downward movement of the piston 17, the liquid from the pimple cavity of the main cylinder 1 is displaced through the pipeline 27 into the power cylinder 2, compressing the spring 8, and moving the piston 7 with the pusher 6, which pushes the waste 31.

Claims (1)

Invention Formula A device for feeding piece blanks into the treatment area and removing parts and waste containing a movable plate associated with a drive, a fixed plate on which a magazine for placing a stack of blanks is installed, a guide tray for moving the blanks, a push rod for moving the blanks from the magazine to a guide tray and removal of parts, and a pusher for disposal of waste, located under the gantry pusher, which converts a mechanism that binds the movable plate to the sliding pusher, characterized in that The purpose of increasing reliability in operation is that it is equipped with a sensor connected to the drive and installed with the possibility of interaction with a sliding pusher, the transforming mechanism is made in the form of three power cylinders connected by pipelines and having bodies fixed on a fixed plate, spring-loaded arms arranged in housings and supporting rods, the gate pusher being connected to the rod of one of the power cylinders, the ram for crushing waste and the stem of the other power cylinder, and the movable plate pivotally connected to the rod of the third power cylinder.
