Abstract
Bar loader mechanism for automatic machine tools, and comprising a warehouse in inclined plane and a guide for the bars that extends horizontally, is disposed at the base of the inclined plane and is constituted by a fixed lower part and an upper movable part forming a sliding conduit for the rod, in which said rod is thrown by means of an exhaust device when the parts forming the guide are open, further comprising a rod-shaped pusher, intended to slide in said conduit and linked, externally to the guide, with a drag chain that carries forward and backward travel strokes, characterized in that the movable part of the guide is composed of a plurality of sections of lesser length than the length of the guide. Distance between the active end of the pusher and the point of attack of the latter to the drag chain, and because it is foreseen an invertible motor member which drives this chain through a first transmission comprising a friction clutch, and a second transmission having a smaller ratio than that of the first and which is engaged during the entry of the bar into the machine tool by means of a removable clutch; a cyclic group, driven by a tree that rotates with the development of the drag chain of the pusher and activates sensitive means, correlated with the positions of the latter in the guide, and a motor driven by said sensitive means, which leads a cyclic actuating lever of a system of levers for opening and closing said sections constituting the movable part of the guide, said lever system being able to determine the opening in succession of the individual sections.

DEVICE FOR DAILY DISTRIBUTION OF DETAILS 1 The invention relates to the loading devices of machine tools. Devices are known for single-piece delivery of parts from a magazine equipped with a gate, by means of a back-to-back movable gate that is connected to a drive. increases the stroke of the gate. The proposed device differs from the known ones in that the flap is made movable in a vertical position and pivotally connected on spring-loaded forked lever cooperating with a drive shibera.Gakoe performance reduces the magnitude of the stroke shibera.Ia FIG. 1 shows the proposed device; in fig. 2 is a section along A — A in FIG. one; in fig. 3 shows a section B — B in FIG. one; in fig. 4 - the position of the gate at the beginning of its working stroke. The device consists of a magazine 1, a movable damper 2, which is pivotally connected to a spring-loaded forked lever 3, interacting with a cam actuator 4, a gate valve 5, equipped with a spring-loaded lever 6 and a link 7. Rear wall of the magazine 1 has a spike 8. From the cam drive 4 by means of the levers 3 and 6, the movement is transmitted to the gate 2 and the gate 5. While the gate 5 moves to the left (according to the drawing), the slide valve 2 descends sharply downwards and takes the lowest position before post 5 de It will fall to the height of one piece 9. When sliding 5 to the right (according to the drawing), it must send some distance and t before viewing with part 9, the moving flap 2 should rise to its extreme upper position during this time, only after this detail 9 served on a working position. The spike 8 in the wall of the magazine 1 enters the groove of the gate b. When gate D goes to the extreme left position (according to the drawing), item 9, having lowered from store 1 to 15, will be bounded on one side by a thorn b, and on the other, by lowered movable damper 2, which will not give part 9 to be flushed B from right to left 20. Item of the Invention A device for single-piece delivery of parts from a magazine equipped with a shutter, connected with a return actuator of a movable sliding gate, characterized in that, in order to reduce the slide stroke stroke, the shutter is made movable in a vertical direction. papravenlen i30 pivotally connected with a spring-loaded fork-shaped lever, interacting with the gate drive.
Machine for the manufacture of wire several bending tools mounted on a stationary carriage and a slider with a crank drive, with a wire feeder in the form of a spring-loaded carriage with a wedge clamp
