SU292516A1 - Device for removing excess zinc during hot-dip galvanizing - Google Patents

Description

The invention relates to the application of hot coatings.

A device for removing excess zinc during hot-dip galvanizing is known, which contains a mechanism for transporting pipes from a bath, a nozzle and a feed mechanism tpy6 to a nozzle.

The proposed device is characterized in that in it the pipe feeding mechanism to the nozzle is made in the form of a trolley moving along the monorail, on which a folding lever with a nozzle is attached, connected with a hose of compressed air and a roller in contact with a copier located

dor trolley

 This improves device performance.

properties.

FIG. 1 shows the proposed device, a plan view; in fig. 2 is the same side view; Mr. FIG. 3 - section aa and fng. 2

The installation consists of a mechanism 1 for transporting pipes from a bath, a nozzle 2, and a mecha® ® a according to the tube to the nozzle 2., mounted in the form of a monorail trolley 3, on which a fixed lever 4 with a nozzle 2 is attached.

the connected hose 5 with the compressed air line, and the roller 6 in contact with the cam 7, located: ...- under the if: bed 3.

The mechanism for transporting pipes from into ;; .-- they are made in the form of an inclined BINT (roller table. Above the rolling table oiv, at an angle r; don: movement of the pipe is set to the right; o1Ts: -3, 8, along which the line is the ends coming from the vandes

From the frame of the roller table oiorels is insulated by textolite plyuklakkak and 10. I Turning on and off the compressed air; - the automatic and with the help of an electropneumatic valve (on cher-and zhvh not shown).

Rybotasg device follows image

At the initial moment, the trolley of 3 dits in the extreme lower position is set at 1 in this position, the reztuzpl of the shock absorber 11.

 can be changed depending on the diameter of the pipe being processed; it is located on the guide rail 8 at the point of passage of the front bent tube.

When the galvanized pipe leaves the bath with the melt, the front end of the pipe, sliding along the rail 8, catches the tip of the nozzle 2 and centers it in it. At the moment of contact of the pipe with the nozzles 2, the electrical circuit closes. As a result, the electro-pneumatic valve is withdrawn, and compressed air begins to flow into the pipe; -Removes the zinc strip from the pipe.

Under the influence of the moving tube, the trolley 3 begins to move upwards p6 to the monorail 9, for a predetermined time of the trolley movement, TbiM is blown with air,

In the set position, the roller rolls onto the protrusion of the copier 7, as a result, the folding lever 4 turns to a certain angle and thereby retracts the nozzle

from the end of the pipe. The circuit opens and the electropneumatic valve stops supplying compressed air. The finished pipe is fed further to the refrigerator, and the release from the pipe of the cart 3 under the action of its own weight returns down to the stop 11, i.e., to its original position, and. the cycle repeats.
