Description

one

The invention relates to the mechanization of technological processes of processing sheet material by pressure and can be used to separate the sheet from the foot and feed it to the press.

A device for separating a sheet from a foot and supplying it to a press is known, which comprises a sheet store installed at the base and a rod driven by a movable part of the press and carrying a slide pusher interacting with the sheet 13.

The known device does not provide the possibility of separation from the foot of sheets having different dimensions.

The purpose of the invention is to eliminate this drawback.

The goal is achieved by the fact that the pusher is mounted on the head with the possibility of moving along it and provided with a mechanism for its fixation relative to the rod, made in the form of a two-arm lever pivotally fastened on the pusher, interacting with one end with the rod, the stop mounted on the base with the possibility of adjustable moving and periodically entering

in interaction with the other end of the two shoulders arm.

The MarasHjia wall, located on the side of the sliding pusher, and one of the adjacent walls can be installed with the possibility of a regulated movement.

FIG. 1 shows the proposed device, a general view; in fig. 2 0 device mounted on the processing machine, in particular the press.

A device for separating the sheet from the foot and feeding it to the press, co5 holds a sheet store 1, a rod 2 on which teeth are made which engage with gear 3 mounted on shaft 4. Gear 5 also is mounted on shaft 4. entering into engagement with the toothed sector 6, spring-loaded spring 7. On the rod 2 is mounted with the ability to move along it the gate plunger 8. On the gate plunger

5 8 a retainer is mounted, its fixing is relative to the rod 2, made in the form of a hinged spring-loaded two-arm lever 9, which interacts with one end with the rod and the other with the stop 10. The stop 10 is mounted on the base 11 with the possibility of adjustment movement and fixed by a screw 12 The wall 13 of the magazine 1 is installed with the possibility of adjusting movement and is fixed by a screw 14 mounted on the bracket 15 mounted on the magazine 1. The rod 2 moves in the sleeve 16. The side wall 17 of the magazine 1 is installed with the possibility of adjusting movement and is fixed in a predetermined position by a screw 18. The base 11 is made in the form of a press 20 mounted on a base 19, on which several stores are installed 1. The bottom 21 of the store 1 is connected with a lifting mechanism 22. There is a tooth on the ring. A rotary support 23 is mounted on the stanion 19 of the press with the help of two semi-axes 24 and the plates 25 are fixed on it with the cutters 26, as well as the rotary clamping bodies 27 and 28. The axles 24 are mounted on columns 29, with protrusions 30, interacting with an ax 31, mounted on the top plate 32 press. On the frame 19, another ring 33 is mounted, carrying tables for stopping 34 blanks 35. The rings are driven by the actuator 36. The material 37 enters the gripping bodies 27 and 28 from the magazine 1 through an opening 38 made in the front wall 39 of the magazine 1. On The top plate 32, fixed on the slider 40, is mounted on the ha 41 and the pawl 42 is hinged on it. The device for separating the sheet from the foot and feeding it to the press works as follows. The line 34 of the sheet material 37 is placed in the shop 1, the walls 13 and 17 of which are configured to a certain width and length of the material. The stop 10 is installed in a predetermined position and fixed with a screw 12. With the working stroke of the slider 40, blanks from material 37 are cut. During the pressing of the press 40, the gear sector 6 turns up from the tank 42, and through gear 5, shaft 4 and gear 3 leads in motion the rod 2. The pusher gate 8 acts on the bottom sheet of material 37 and through the opening 38 moves it to the gripping bodies 27 and 28. The two-arm lever 9 interacts with one end with the stop 10 and rotates around the axis of the hinge. The other end of the two shoulders lever 9 leaves the interaction with the rod 2. In this case, the slide pusher 8 slides along the rod 2 and does not move relative to the magazine 1. When the pawl 42 leaves the interaction with the gear sector 6, the spring 7 rotates the gear sector 6 and it moves the rod 2 to the starting position. The rod 2 moves the gate pusher 8 also to its original position, and the double-arm lever 9, the exit from the interaction with the stop 10, fixes the gate pusher 8 on the rod 2. At the same time, the stop 31 fixed on the top plate 32 acts on the protrusion 30 and raises a pivot bearing 23, which pivots about the half-axis 24. The gripping members. 27 and 28, pivoting, lay the material 37 on one side of the pivot bearing 23. Then the cycle is repeated. Claim 1. A device for separating a sheet from a foot and supplying it to a press, comprising a base shop for, stops of sheets and a rod set in motion from the movable part of the press and carrying a slide gate pusher interacting with the sheet, characterized in that , in order to provide the possibility of separation from the foot of sheets having different, the pusher is mounted on the rod with the ability to move along it and is equipped with a mechanism for its fixation relative to the rod, made in the form of hinged to sense barely two-armed lever interacting with one end of the rod, the stop, mounted on the base with the possibility of adjusting the movement and periodic inlet into engagement with the other end of the double-armed lever. 2. The device according to claim 1, wherein the wall of the magazine is located on the side of the sliding gate, and one of the adjacent walls is installed with the possibility of adjustment movement.
