Description

Object - Utility Model

Device for applying coatings on products

The utility model relates to the field of coating products and can be used in the hardware industry in the production of bimetallic wire and coated rods, as well as blanks for various parts.

A device for applying a coating of aluminum and its alloys to a wire is known, comprising a container with heated coating metal, a punch for extruding aluminum, a matrix for providing a profile profile for a bimetallic steel-aluminum wire and mandrel, designed to hold and center the core in the crimping zone (see book B .K. Korol, MS Gildenngorn, Fundamentals of technology for the production of multilayer metals. M: Metallurgy, 1970. S.168-170, Fig. 62).

A disadvantage of the known device is the manufacture of a product with a very poor coating quality due to the lack of adhesion of the coating material to the product, since both materials are in the solid phase, as well as due to the large variability of coatings1; coating appearance as a result of core displacement during crimping of the product.

The closest analogue is a device for continuous casting of metal lengthy workpieces containing a container, the cavity of which is filled with the melt of the coating material, a gate mounted coaxially to the container with an axial channel for pulling the workpiece, a refrigerator and a heater (see RF patent No. 2069598, B 22 D 11 / 00).

The disadvantage of the prototype is the low quality of manufactured products due to the partial ingress of sludge into the material of the applied coating, as well as the production of a shell with an uneven coating thickness as in:: ir: io-vB i. : f Vg ™ ™ 3

the size and length of the product due to the lack of centering it in the manufacturing process.

The technical problem to which the utility model is directed is the manufacture of products with a high-quality coating uniform in thickness.

The stated technical problem is solved in that the known device for coating products, containing it; its capacity, the cavity of which is filled with the melt of the coating material, a sprue installed coaxially with the axial channel for pulling the workpiece, a refrigerator and a heater, according to the change, it is equipped with a hermetically installed on the container with a lid with holes for supplying the coating material and a device for centering the workpiece, which is installed in the lid coaxially to the channel the runner, the sprue is made to the entire height of the tank and in the area in contact with the melt of the coating material, it is equipped with radial channels communicating with the axial channel, which are located at different levels along the height of the grooved section, and in the horizontal plane of each level with uniform angular pitch, at this heater is installed outside the tank with the coverage of its perimeter, the refrigerator is made annular and installed under the tank, and the gate is fixed at one end in the roof and the other in the ring refrigerator.

The diameter of the radial channels is 1.2-1.5 of the diameter of the axial channel. In addition, on the peripheral sections of the radial channels, additional channels are made in the shape of the axial channel.

The essence of the utility model is illustrated in the drawing, where:

figure 1 shows a General view of the device for coating products, longitudinal section;

A device for coating a product contains a container 1 (Fig. 1) with a hermetically sealed cover 2. The cavity of the container 1 is filled with a melt 3 of the coating material. Coaxial capacity 1 installed sprue 4 (Fig. 1-4) with an axial channel 5 intended for pulling the workpiece 6 (Fig. 1).

The sprue 4 (Fig. 1-4) is made to the full height of the container 1, while one end is rigidly fixed in 1 flash 2, and the other in the refrigerator 7, which has an annular shape and is located under the capacity 1. As a refrigerator 7 (Fig. 1) can be used any known refrigerators, for example, water. The cover 2 (Fig. 1) of the container 1 is provided with two holes: an opening 8 for pouring the coating material in the form of liquid metal into the container 1, and an opening 9 for supplying the coating material in the form of ingots to the latter. In addition, on the cover 2, coaxial to the axial channel 5 of the sprue 4, a device 10 is provided for centering the product 6 drawn through the axial channel 5. In this case, the device 10 provides centering of the product 6 in the area between it and the pulling rollers 11.

In addition, the sprue 4 in the area in contact with the melt 3 of the coating material is provided with radial channels 12 (Fig. 1-4), which are located at different levels along the height of the specified section of the sprue 4, and channels 12 in the horizontal plane of each level (Fig. 2, 4) are arranged with a uniform angular pitch. In this case, the radial channels 12 (Fig. 1-4) are made communicating with the axial channel 5. The diameter of the radial channels 12 is 1.2 - 1.5 of the diameter of the axial channel 5. Such a structural embodiment of the claimed device allows to ensure the coating process on the product 6 to provide uniform supply of the melt of the coating material, both along the perimeter of the product 6 and along its length, as a result of which the coating will have the same thickness and high quality over the entire surface of the product.

the supply of the coating material to the surface of the product 6 stretched through the axial drip 5, as a result of which, on the surface of the workpiece 6, the thickness of the coating will be observed, which reduces the quality of the product.

Perform radial channels 12 with a diameter greater than 1.5 of the diameter of the axial channel 5, is also impractical, since in this case the strength conditions of the gate 4 will be violated, which will lead to its rupture.

In addition, in the inventive device, the heater 13 is installed outside the tank 1 with the coverage of its parameter. As a heater 13, any known inductor can be used. This allows you to maintain the temperature of the melt of the coating material in optimal ranges, providing high casting properties of the material to create high-quality coatings on the product.

To enable coating at the same time on several products in the sprue 4 on the peripheral sections of the radial channels 12 (Fig. 3,4) additional channels 14 are made. Moreover, the shapes and dimensions of the additional channels 14 correspond to the shape and dimensions of the axial channel 5.

A device for coating products operates as follows. The workpiece 6 (Fig. 1), on the surface of which the coating is applied, is placed in the axial channel 5 of the gate 4. From here; more than 6 in the processing zone is centered using the tool 10 and pull rollers I. Then, the refrigerator 7, the heater 13 are subsequently turned on. The coating material is fed into the preheated container 1 in the form of liquid melt 3 through the hole 8, or in the form of solid material, for example, ingots into the hole 9. At the same time, the level of the melt 3 with a predetermined temperature is supplied to the container 1 so that the radial channels 12 in litni e 4 constantly under the bath surface 3. Thereafter include tyanzotsie osuschestv.11yayut rollers 11 and the pulling of the workpiece 6 in the axial channel 5 through the melt 3 of the coating material. In the process of broaching

of the product 6, the melt 3 through the radial channels 12 is inserted into the axial channel 5 and washes the surface of the product 6. At the same time, the centering and tension of the product 6 in the processing zone allows coaxial positioning of the product 6 in the axial channel 5, while ensuring a uniform gap between the wall of the channel 5 and the surface of the product 6, which is filled with melt 3. This leads to the creation of a coating layer of the same thickness on the surface of the workpiece 6 along the perimeter and along the length of the product 6. As the product 6 is pulled along the axial ala 5 Last, in the lower part of the gate 4 arranged in the annular cooler 7, cooled to the crystallization temperature po1fytiya material. In this case, the finished product 6 has a high frequency of the coating material due to the fact that the coating is formed by a melt in which there is no slag, oxides and other contaminating components, it also enters the surface of the product through radial channels located below the melt mirror.

Thus, the claimed device allows to obtain both single-layer and multilayer products with high-quality and uniform in thickness coating.
