Description

one

The invention relates to die tooling.

A stamp is known with a vertical plane of the connector, on the fixed part of which there is a matrix with two nodes placed on opposite sides to hold the workpiece in a vertical position, each of which is provided mounted on the fixed part of the stamp, movable in a plane parallel to the plane of the connector, and installed with the possibility of mixing under the action of the iris in the direction towards the center of the stamp and placing "a given distance from the mirror of the matrix with the element driven by the | displacement in n otivopolozhnom position by a wedge mounted on the movable die part.

A disadvantage of the known stamp is that it cannot be adapted for multipositional stamping, since the holding units of the workpiece in the vertical position have a relatively complex structure and large dimensions.

In order to eliminate this drawback in the proposed stamp, the movable element of each of the assemblies is made in the form of a pivotally fixed, rotatable in a plane parallel to the plane of the connector of the two-armed L-shaped lever, which has one

shoulder over the matrix zarkal at the opened position of the stamp and interacting with the other shoulder with the wedge when the parts of the stamp approach each other ..

FIG. 1 and 2 depict respectively the fixed and movable parts of the stamp; in fig. 3 — unit for holding the workpiece in a vertical position; in fig. 4 shows a section along A - A in FIG. 3

The stamp with a vertical connector contains a fixed I and a movable 2 parts, on the first of which is mounted a tray 3 and a die with a ring 4, on which abutments 5 and two assemblies for holding the workpiece opposite the die are mounted, forming a channel for moving the workpiece. Each of the nodes consists of two elements, one of which 6 is fixedly mounted on the ring 4, and the other is made in the form of a two-armed L-shaped lever 7, pivotally connected to the first one, which can be rotated in a plane parallel to the plane of the connector and spring-loaded with a twist spring 8 .

The rotation of the L-shaped levers 7 is controlled by a wedge 9 together with a safety gear 10, a punch 11 and a puller 12.

The stamp works as follows.

The processing of a round billet into the stamp through the tray 3 hits the stops 5 opposite the die. In this position, the workpiece is held from the displacement in a plane parallel to the plane of the connector and perpendicular to the direction of supply of the connector, by fixed elements 6. The L-shaped levers 7 fix the workpiece in a vertical position. When approaching parts 1 and 2 of the punch, the catcher 10 enters the central opening of the workpiece and centers it. In turn, the wedge 9 also affect the shoulders of the levers 7, having bevels. As the parts of the punch wedge 9 approach, the levers 7 gradually turn, remove them from the surface of the workpiece and release the matrix mirror. Then, with the clamp-remover 12, the workpiece is pressed against the die and the part is cut. When the movable part 2 of the stamp is removed from the stationary 1, the stamped part is removed from the punch 11 by means of a pressing-down puller 12 and, under the action of gravity, retains its vertical position, moves to a discharge tray (not shown). After disengagement of the wedges 9 and the levers 7, the latter springs 8 return to their original position. Item of the Invention A stamp with a vertical plane of a connector, on a fixed part of which a matrix is installed with two nodes located on opposite sides to hold the workpiece in a vertical position, each of which is provided with a mounted on a fixed part of the chip, moving in a plane parallel to the plane of the connector, and installed can be moved under the action of a spring in the direction towards the center of the stamp and placed at a predetermined distance from the mirror of the matrix by an element with a drive further in the opposite direction from the wedge fixed on the movable part of the punch, characterized in that, in order to simplify the structure of the work holding unit and to enable the multi-position stamping, the movable element of each of the assemblies is hinged, rotatable in a plane parallel to the plane connector, two-armed L-shaped lever, located one shoulder above the mirror of the matrix in the open position of the stamp and interacting with the other shoulder with the wedge at the approaching cha Tay stamp.
