Description

The invention relates to the processing of metals by pressure, in particular to devices for cutting, and can be used to produce dimensional blanks of strip and sheet material.

The aim of the invention is to increase the reliability of the device for cutting sheet material.

1 shows a device for cutting sheet material, a general view; figure 2 is a section a - a in figure 1; on fig.Z - section BB in figure 1 (the position when the edge of the segment); figure 4 - the same, when cutting the workpiece.

The device for cutting sheet material comprises a base 1, which is equipped with a cutting mechanism 2 with movable working parts 3, a pneumatic actuator 4, a drive control system 5 with an air distribution valve 6, an understay 7 an emphasis 8 of the first cut (edge cutting).

On the stand 7 is mounted movably stop 9 and rigidly fixed 1N1evmolozotnik 10 with the possibility of the interaction of the wall And the unor with the rod 12.

In the exhaust port of the distributor 10, a npuner 13 is installed, connected to the air distribution valve 6 by means of the hose 14 and the choke 15.

The stop 8 by means of the lever 16 is pivotally connected to the stop 9, and the working part 17 of the unor 8 is exchanged in the slot 18 of the base with the possibility of horizontal movement together with the stop 9 and the swing in the vertical position relative to the hinge 19. The stop 8 is kinematically connected with the stationary working members 3 by means of a firmly fixed crownng 20 and a tacker 21 fixed on the moving members 3. In the initial upper position, the nore 8 is held by the spring 22.

The device works as follows.

In the initial position, the cutting mechanism 2 and the pusher 21 closed on it are in the upper position. The rod 12, the stops 9 and 8 under the action of compressed air are in the left extreme position. The stop 8 under the action of the spring 22 sub t and its working part 17 blocks the path of the material.

G1Appenables material. butt presses pa an emphasis 8 and turns it over: 5 it stops 9, which with a wall 11 presses the rod 12 and activates a pneumatic actuator through the system. Occurs from () szk krkpgki material and punching off.

At the same time, the pusher 21, onus, presses on the crown 20 and B1-pushes the stop 8 from contact with the material. Under the action of compressed air, ppo 12, ugurs 9 and 8 move to the left, with yiiop 8 part 17 resting on the plane. material: 1a, parok p: egos outside the cutting area.

With the further supply of material, chopped off eio of the torus; with a cation on the wall 11 and HJTOK 12 vk: | yuchaet pneumatic actuator, there is a piece of the workpiece, which is lost. pulls out knives from the zone, and the unnor 9 and ngkhok 12 are not moved and the go / go position.

Claims (2)

1. A device for sheet material sheet, containing a base, a cutting machine with a movable part, a single cutting tool, a control system for driving a cutting mechanism with a control element, rigidly sm1, a shooting gallery () on the base, and two stops, one in a row: placed behind the movable cutting tool in the direction of supply of the material being cut, the nerve of which is mounted on a spring loaded lever mounted with the possibility of swing, and the second in the direction of the cut lever a material, characterized in that, with a slight increase in reliability, a second emphasis is placed on the device, with the possibility of reciprocal-postunational movement in the nodashes of the material being cut and interacting with; The control element, a spring-loaded lever | - is pivotally mounted on the second stop, and the movable part of the cutting mechanism is installed with the ability of the pusher to interact with the spring-loaded p1z1chag, while at the base there is a through groove under the first unor. 2. Device but ii. 1, distinguished by the fact that the drive mechanism of the cutting machine is 1shvmaticheskuyu, and ele.men.t u1fav. released, 1nen in the form of a glosser.
