SU5960A1 - Tool for making sleeves for the outlet of the crucible - Google Patents

Description

The present invention is intended to produce replaceable sleeves for the outlet openings of thermite melting crucibles, the lower part of which quickly becomes unusable due to high temperature.

In FIG. 1 shows a vertical section of the proposed tool, FIG. 2 is a vertical section of the sleeve manufactured; FIG. 3 is a vertical section of a glass with a punch; FIG. 4 is the same, the backing ring; FIG. 5 is the same, slingshot and fig. b is the same cylinder to push the molded product.

The proposed device for producing sleeves for the outlet openings of the crucible consists of a steel cup A (Fig. 1), the upper inner floor of which exactly matches the outlines of the outer walls of its sleeve B (Fig. 2); on the shoulders a and a glass A puts a ring b forming the bottom of the sleeve B.

The second part of the fixture is a cup E, in the center

which is fitted with a punch d, turned along a spherical surface corresponding to the inner surface G of sleeve B. The walls hh of glass E serve, as it were, as guides-centering punch d relative to the hollow upper part L of glass A. At the start of work, into glass A, on shoulders A ring b is laid, the hole p of which is covered by a circle cut out of thick paper. In the cavity L of glass A, a refractory ceramic material specially prepared for bushings is packed by tamping to the g-S line. Then, the cup A is placed with its bottom hole on a specially machined lining C, with the stem R provided with a hole T. Ring D is preliminarily placed on the shoulders x, y of the lining C; punch d of cup E, the entrance under the action of a press into the mass, produces the first side pressing, until the points of the stanna of the station E and the points g-s of the cup A coincide, after which the pressing goes from top to bottom, in the upper part of the sleeve until .

until the cup E is on the ring D v (the t-fi.stakan E line does not coincide with the k-i line of the A.

Further, to press the bottom of the sleeve vertically, remove the cup A from the lining C, take out the ring D, put the cup A again on the lining and press it with a press; ring b rises up and presses the bottom of the sleeve to the required limits. All the excess mass remains in the spear-spherical space formed by the semi-oval grooves of q-d cup A and cup E. The height of ring D, as well as the distance value td cup E and rk cup A are different, depending on the material going to cooking sleeves.

In order to remove the ready-made pressed sleeve from the cups, remove them from the lining C and the ring D, put on the ring H (Fig. 4) and the slingshot N with four fingers S (Fig. 5) squeezing through the channels 5 of the glass squeeze under the press cup A from cup E, then put cup A on the lining C, on which the hollow cylinder M is mounted on rod R (fig. 6); pressing the glass And on top, remove the molded sleeve B.

The subject of the patent.

A tool for manufacturing sleeves for outlet holes of thermite melting crucibles, characterized by the use of glass E (Fig. 3) with a punch d inside, which is worn when pressed onto the glass A (Fig. 1), which serves as a matrix and having a hole in the bottom covered by a ring b The core / pads C enters into the hole, and the dental punch d has a cylindrical base, tp, at the sides of which there are 5-6 holes that serve to pass the fingers S, S of the slingshot N (Fig. 5), with which the cup Pushed out of stack on E after replacing the lining With ring H (Fig. 4).
