Description

The invention relates to the field of mechanical engineering,, 3 Particularly. To the equipment of the manufacturing industry, which is suitable for leresarke of three face-pieces of lress-form volcanic-erection presses.

From: a device for cutting is known: the number of multi-storey press forts, containing a mechanism for closing and opening of parts of a multi-storey press-frm, the lifting bar of their lifting was lowered, made in the form of a clamp of the upper part of the mold and telescolic the brackets of the lower average h of the press-forts clamps: m 1 connected with it;

The disadvantage of such a device is the complexity of the construction.

Another known device is for replicating the three-plate molds, which contains a mechanism for displacing the molds 5 1 in the form of power | C: or HI with a fixed gripper, interacting with it, mounted on one of the plates a mold with a fork, a lifting mechanism for the upper plate in the form of a ram cylinder a, connected by means of holann to the guide plate for the upper plate, the mechanism of movement of the bottom plate with the guide plate, and the mechanism for pushing products out of the middle plate, having a plate with ejectors 2

This device is equipped with separate mechanisms for moving the middle plate.

lifting 5i is pushing out the spin, which reduces its performance.

The purpose of the invention is to increase the productivity of the device by optimizing its KOiHCTipyKunn

The goal is achieved by the fact that, in the proposed device, the mechanism for moving the lower plate — and the mechanism for ejecting the products of the middle plate — is designed as a power pin Linara and a two-arm lever, one arm of which is pivotally connected to the rod of power ildre, and on the other is mounted The hook and the guide for the bottom plate are connected with a two-arm lever by means of a pull-rod.

FIG. 1 shows the proposed device; in fig. 2 is a section along A-A in FIG. 1; in fig. 3 is a section along BB in FIG. 1 with closed middle and lower il.itah; FIG. 4 shows the device in the working position; in fig. 5 - fastening the finger in the guide plates of the bottom plate; in fig. 6 is a view along arrow H of FIG. five.

The device contains a mounted-on-aame / mechanism for moving molds to the E-idea of the power cylinder 2 with a gripper 3 fixed on its brush and moving}) ms. in the guides 4 and in engagement with the fork o, which is fixed in place on the middle section and the press-form.

The lifting mechanism of the upper plate of the mold has coloins 7, on which it is fixed, and olorna l-ita 8 with a cylinder 9 installed by it 9. The stem of the last: one is connected to the plate 10, moving along the columns 7, and the bearing guide // for the upper l .ites 12 -; ress-fr.r.my.

The mechanism for moving the lower spacecraft truss and the mechanism for ejecting the products from PLATE 5 is made in the form of a power cylinder 13, the rod of which is connected to one shoulder of the two shoulders lever 14 interacting with the other shoulder using fingers / J with the guides 16 of the lower frame P of the bearing bearing 18. from the ejector m: and 19. The lever 14 is mounted on the axis of the 20 axis with a boat, providing weaning of the plate 17 and extrusion of products, and an assembly mounted with the possibility of rotation around the axis 21.

The device works as follows.

After opening the press (not shown on the figures), the gripper 3 engages with the fork 5, when the cylinder 2 and the press head are machined, the shaft moves from the press to the device for lifting the arbor. Plates 6, 12, and 17 enter the respective guides 4, P, and 6. Then cylinder 9 is activated, which raises plate 12 to a certain height.

At the end of the lifting of the plate, cylindrical 13 turns the lever 14, which with the help of fingers 15 rotates downwards relative to the axis 21 and the anti-rifles 16. At the same time, the plate 17 is detached from the plate 6 and deflected by an angle to ensure the load of the products. At this time, the plate 18, which is attached to the lever 14 with the ejector 19, moves to the surface 6 and pushes the product out. After that, cylinder 13 returns to its original position the lever 14 and all the components with which it is attached. The plate i / 7 approaches the plate 6 and at this time the laying of grooves in the sockets of the plate 6 occurs. Then the cylinder 9 is activated and the plate 12 is placed on the plate 5 - the mold is closed.

The press mold is closed using cylinder 2 1 to move to the press. The vulcanized mold is fed to the rewrite position, and the cycle is repeated.

The use of the proposed device due to the simplification of its design makes it possible to improve the quality of the products formed in the former molds and increases labor productivity.

Formula and 3 optics

The device for the p. E) rezd dk | And three-plate molds, designed by the Mechanism of ne, relocation of Molds in the form of a power cylinder with fixed on its sht: ke grip, interacting: m with -sized on one of the plates press-form we fork, the mechanism of lifting the top 1PL1ity in the form of a power cylinder connected by means of columns with a guide for the top plate, the mechanism for moving the bottom plate with the guides and the mechanism for pushing products out of the middle plate, | with ejectors, about the fact that, in order to increase The productivity of the device is simplified; {its construction, non-displacement mechanism (bottom plate and ejection mechanism) of products from medium-sized materials are made in E, the idea of a power cylinder and a two-armed lever, one arm of which is pivotally connected with the stem of the force cylinder (on the other one — mounted on the ejector plate, and the guide for the lower plate is connected to the double-arm lever by means of a single plate.
