Abstract

FIELD: forging press equipment, namely structures of powered presses.

SUBSTANCE: press includes drive unit mounted in housing and connected with drums also mounted in housing with possibility of mutually opposite simultaneous rotation around parallel axes. Die holders having carrier in end of each holder are jointly mounted in drums and they are equally spaced from rotation axis. Carrier is in the form of cylinder. Each carrier is mounted with possibility of relative rotation in carrier bar. The last is mounted with possibility of relative rotation in housing eccentrically relative to drum rotation axis. Eccentricity value of rotation axis of carrier bar relative to drum rotation axis is equal to eccentricity value of axis of articulation joint of die holder and drum relative to axis of carrier. Carriers are spaced from rotation axis of carrier bar equal to distance of said articulation joint axes from drum axis.

EFFECT: simplified design of press.

Description

The invention relates to forging equipment, in particular to the design of mechanical presses.

A drum type press is known, comprising a drive located in the bed, with which drums are connected, installed in the bed with the possibility of counter synchronous rotation relative to parallel axes, on the drums at equal distance from the axis of rotation, punch holders with two cylindrical leads at the end of each of them are mounted, and each of the leads is located in a closed curved groove made in the frame [1].

A disadvantage of the known technical solution is the design complexity due to the execution of curved grooves.

The invention is aimed at simplifying the design of the press.

This is achieved by the fact that the press comprises a drive mounted on the bed, with which drums are connected, mounted in the bed with the possibility of counter-synchronous rotation relative to parallel axes, on the drums at equal distance from the axis of rotation, punch holders with a leash made in the form of a cylinder at the end of each of them, each of the leashes is installed with the possibility of relative rotation on the carrier, and the carrier is installed with the possibility of relative rotation on the bed, eccentric to the axis of rotation of the drum , The eccentricity of the axes of rotation of the carrier drum and is equal to the eccentricity of the axis of articulation of the shoe with the drum and the axis of the guide, and the leashes are spaced from the carrier rotation axis, equidistant from the axis of the drum axis articulations of the shoe with the drum.

The drawing shows a section of a drum-type press with the closest approach of the die holders.

The drum type press comprises a drive (not shown) located on the frame 1, connected with shafts 2 installed in the frame, on each of which drums 3 are fixed, the axes of rotation of which are parallel. On the drum at an equal distance from the axis of its rotation, punch holders 4 are pivotally mounted, each of which has a leash on the end face made in the form of a cylinder and mounted with the possibility of relative rotation in the carrier 5 in an eccentric axis of the pivot joint of the punch holder and the drum. The carrier is installed with the possibility of relative rotation on the bed eccentric to the axis of rotation of the drum. In this case, the eccentricity of the axes of rotation of the carrier and the drum is equal to the eccentricity of the axis of the hinge connection of the die holder with the drum and the axis of the leash, and the leads are located at a distance from the axis of rotation of the carrier, equal to the distance from the axis of the drum of the axes of the hinge joints of the die holder and the drum.

With synchronized oncoming rotation of the shafts 2 with the drums 3, the die holders 4 move around a circle passing through the centers of their articulated joints with the drums. In this case, the carrier 5 rotates relative to the bed 1 and constantly guides the die holder for its leash parallel to the axis passing through the centers of rotation of the drums. The stamp holders of different drums move progressively in a straight line relative to each other, ensuring stamping of the tape with a tool installed on them and moving it in the feed direction.
