RU2486984C1 - Device to grip container working sleeve for removal from press zone - Google Patents

Abstract

FIELD: process engineering.

SUBSTANCE: invention relates to metal forming, namely, to: devices for gripping and withdrawing the parts from press working zone, particularly, for gripping vacuum press container working bush. Device comprises squeezing bush and thrust washer. Squeezing bush case incorporates spring-loaded blocks arranged radially in one plane, on both sides relative to axis. Hydraulic cylinder and retainer are arranged opposed in perpendicular plane. Said blocks and retainer have holes. Flexible element is fitted in said holes. Flexible element ends are secured at hydraulic cylinder rod.

EFFECT: reliable grip.

Description

The invention relates to a device for capturing a working tool in presses for subsequent dismantling and removal from the working area.

Known as an analogue is the design of a device for gripping a part for automatically changing tooling (see, for example, RF patent No. 2365455, B21D 43/01, 05/30/2007). The device comprises a beam with a gripping mechanism and a drive device for moving parts. A disadvantage of the known device is the complexity of the design and the inability to capture the working sleeve of the container, which has a significant mass.

Of the known constructions of devices for capturing the working sleeve of the container for subsequent removal from the press zone, the closest in technical essence (prototype) is a device for capturing parts made in the form of clamping pliers with a mechanism for their information and breeding (see the Handbook "Forging and Volumetric Stamping of Steel", t.1, Engineering, M., 1967, p. 256).

A disadvantage of the known design of the device for capturing parts is: the inability to center and capture the part, which leads to distortions and jamming of the part during dismantling.

The technical result of the proposed device for capturing the working sleeve of the container is to simplify maintenance by making it possible to capture large tool parts for subsequent dismantling from the press zone.

The technical result of the invention is achieved by the fact that in the device for capturing the working sleeve of the container for subsequent removal from the press zone containing the press-out sleeve and the support washer, the spring-loaded pads are located radially in the same plane on both sides relative to the axis on two sides of the axis of the press, and are located in the perpendicular plane diametrically, on one side, a hydraulic cylinder, and on the other hand, a latch, while the pads and the latch are made with holes in which the flexible element is placed, the ends of which are fixed on the rod of the hydraulic cylinder.

The claimed device for capturing the working sleeve of the container is shown in the drawings, where Fig. 1 shows a device in the initial position in cross section along the line of blocks;

figure 2 is a section bB in figure 1;

figure 3 - the device at the time of capture of the working sleeve;

figure 4 is a cross-section bb in figure 3.

The device includes a press-out sleeve 1, in which spring-loaded wedge-shaped blocks 2 with holes 3 are installed diametrically on two sides. A hydraulic cylinder 4 is mounted on one side and a retainer 5 with a hole 6 on the other side. Through holes 3 and 6 around the circumference a flexible element 7 is missed, for example, a cable, the ends of which are fixed on the rod 8 of the hydraulic cylinder 4.

The operation of the device is as follows.

To unpress the conical working sleeve 9 of the container 10 located in the press (not shown in the drawing), a washer 11 is installed below the working sleeve 9, and a concentric pressing sleeve 1 is placed above the container 10, while the rod 8 of the hydraulic cylinder 4 is in the extended position, and spring-loaded pads 2 stretch the flexible element 7 from the center to the periphery of the device. Then, by the force of the press, pressing through the sleeve 1 onto the container body 10, the working sleeve 9 leaves the container body 10 by means of the washer 11 to the position of its capture by the spring pads 2. After that, the flexible element 7 is pulled by the rod 8 of the hydraulic cylinder 4, which displaces the pads 2 until their interaction wedge surfaces with an outer conical surface of the working sleeve 9. In this position, the working sleeve 9 is securely fixed in the press-out sleeve 1, after which a device for removing parts from the press zone (not shown in the drawing ano) dismantle the working sleeve 9. As a tightening device, instead of a hydraulic cylinder, for example, a screw can be used.

Thus, the device allows more accurately, without distortions leading to jamming, to reliably capture large-sized container parts, for example, a working sleeve weighing 200 kg or more, for subsequent dismantling from the press zone.

Claims (1)
