Description

The invention relates to the processing of metals by pressure and can be used for the manufacture of hollow parts with an inclined flange, in particular the neck of canisters.

A device is known for the manufacture of parts on a multi-position sheet metal stamping press machine. The known device comprises a set of dies for various technological operations located one after another in the technological sequence, and a clamshell mechanism for feeding parts with grippers located symmetrically at each of the dies.

A disadvantage of the known device is that it does not provide reliable spatial orientation of the parts during their interoperational transportation. This is due to the following reasons. For processing parts with beveled end faces of one another, the matrices should have inclined working surfaces, i.e. they are located below the common mirror of the dies. Therefore, the part must be moved not only in the horizontal, but also in the vertical plane. To ensure vertical movement of the part during its interoperational transport, the grippers should have a lever VI

spring construction. Springs have small differences in the characteristics of the dependence of effort on the stroke. In this regard, when closing the grab grips, one of them having a weaker spring can start lifting the part earlier than the other, which will lead to the deviation of the symmetry axis of the part from the vertical position, later, when the second gripper begins to act, when the vertical position is restored semi-finished product is possible to rotate it in the grab feed grabs. When supplying a part with a disturbed spatial orientation to the next stamp, a deviation from the required shape of the part during its shaping is inevitable, i.e. decline in quality. Since the inclined working surfaces of the dies are recessed with respect to the common mirror of the dies, it is not necessary to move the semi-finished product in the vertical plane.

The purpose of the invention is to increase reliability and expand technological capabilities by manufacturing parts with one end inclined relative to the other.

This goal is achieved in that in a device for manufacturing parts on a multi-position sheet-stamping press machine, comprising dies for various technological operations, arranged one after the other in the technological sequence in the direction of supply of parts and each matrix with working planes located in one horizontal plane and a clamshell feed mechanism with grippers located symmetrically relative to the axis of the parts, in the matrices of each of the dies, intended for machining parts with inclined end faces, grooves for moving parts are made having vertical lateral sides parallel to the component supply axis and a bottom parallel to the supply axis and at an angle to the vertical side walls.

The drawing shows a set of dies for molding on a multi-position

sheet stamping press machine, including dies 1 for various technological operations, located one after the other in the technological sequence in the direction of supply of parts

and each having matrices 2 with work planes 3 located in the same horizontal plane and a clamshell mechanism (not shown) with grippers 4 located symmetrically to the feed axis of the parts of each of the dies. Each of the dies, starting with a die intended for machining parts with end faces inclined relative to one another, has a through groove 5 for

moving parts having vertical side walls 6 parallel to the axis of supply of parts and a bottom 7 located parallel to the axis of supply of parts and at an angle to the side vertical walls 6.

A set of stamps works as follows. ..: ... /

A blank 9 is cut out from the roll tape 8, which is fed with a gate 10 to the grip area by grabs 4 of the grab press. Then the part 9 is moved by the grippers 4 along the working planes 3 of the matrix 2. In the dies intended for processing the parts with the end faces inclined relative to the other, the part moves along the inclined bottom 7 of the groove 5. The vertical axis of the part is perpendicular to the working surface 3 of the matrix 2. When moving a part along

the groove of the gripper 4 of the clamshell Feed covers it along the generatrix and keeps the spatial orientation and fixation of the part constant until the final operation is completed.

The use of a set of dies provides an increase in the quality of parts by 20 ... 25%.
