SU15009A1 - Molten Metal Coating Machine - Google Patents

Description

The present invention aims to mechanize the operation of coating metal products with molten metal with the help of two turning tongs and a conveyor belt in the form of a carousel with legs that pick up the product.

The drawing shows a vertical section of the proposed machine.

The coating of metal products with molten metal is performed in a bath provided with a dividing wall 3 in the middle, which prevents the penetration of the molten flux, covering the metal, into the second bath bovine, the surface of which is kept clean by permanently removing metal oxides with a scraper. Conducting the product through the molten metal is performed with the help of two mechanical tongs 5, 6, and further movement of the products through the conveyor in the form of a carousel. The first mites take the product, immerse it in a bath, pass it through a layer of flux and metal, and stop at the lowest position. Axis 1 starch consists of two tubes, enclosed one inside the other. Part b of the tongs is fixedly connected with the outer tube, and the other 6 is pivotally connected with the inner tube. By rotating both pipes with the same angular velocity, the ticks themselves move, and by rotating one pipe relative to the other, the opening angle of the jaws, t, -e, is changed.

force the tongs to grab or lower the product. Rotation of the pipes one into the other is accomplished with the help of gears 7, fitted on both pipes and connected to two sectors S, turned by rollers 9 under the action of fist eccentrics 10. The second mechanical riveters 5, 6 receive the products from the first edge, their lower position. The first rivets release the product and move back, and the second conducts it further through the metal and put it on the conveyor belt. The second mites receive their movement, as well as the first, from the tubular axis 1.

The conveyor is arranged in the form of a carousel, which has several IS grab paws. Each paw 13 rotates about its horizontal axis 13 and, being in the inclined position indicated by a dotted line in the drawing, passes the bucket upwards, after which it receives the vertical position and takes the bucket from the second mites. Upon further rotation of the carousel, the paw again assumes the inclined position indicated in the drawing on the right side, the bucket falls off and then slides over the inclined tolob. A change in the position of the paw is achieved by moving the roller 14 along an appropriately bent rail 15. Rotation of the carousel is achieved either by using gears from the camshaft for uniform rotation, or by the crank mounted on the camshaft with levers and pawl, to get the rotation interrupting while putting the bucket in the paw of the carousel.

The scraper 16 for removing metal oxides represents a metal corner, which can rotate around its axis and move along with the axis with the help of levers and a crank. With its movement, the scraper grabs a plop of oxides, presses it to the side of the pot, lifts it over the bevel and brings it to the edge of the pot.

The rotary tube 17, located at the edge of the bath, aims to collect solid flux and remove it overboard of the bath using a scraper 18.

The subject of the patent.

1. A machine for coating metal products with molten metal, characterized by the use of a tool.

serving for carrying products through the molten metal node by separating wall 2, and a conveyor belt serving for transporting products from the metal tank, of which the first device consists of two ticks 5, in which parts are attached to pipes located one another, turned by sectors of 8 nodes action fist eccentrics 10 on the rollers 9, and the conveyor in the form of a carousel is equipped with a system of lifting paws 12, taking the proper position under the action of the fist chute 15 on the rollers 14.

2. In the machine specified in paragraph 1, use the scraper 16, which serves to remove the oxide film from the surface of the molten metal.

3. In the machine specified in clause 1, the application for removing the film of recycled flux from a device consisting of a rotating Frubs 17 and a scraper 18.
