DEVICE FOR EQUIVALENT COOLING OF A RADIATED PRODUCT

A device for uniform cooling of the deposited product relates to the field of welding and surfacing. When carrying out surfacing work on the restoration of parts due to the characteristics of the process, the melting of the metal electrodes and applying it to a worn surface, there are large heat input. If the part is massive, and the applied layer is small, then the heat input does not lead to dry: natural deformation and warpage of the material. It (de (}} formation) can be corrected during subsequent machining. If the part is thin-walled or complex in shape, then thermal investments have a significant effect ira the geometric parameters of the part being restored, which cannot be fixed)) by subsequent machining.

There are various techniques to reduce warpage of a part. These are preliminary heating and slow cooling, a definite order of Н 1; roller shrinking during surfacing. All this complicates and increases the cost of recovery technology. The surfacing process of worn-out internal surfaces is complicated by that. that the surfacing process is hidden from the eyes of the operator. The process of surfacing thin-walled parts with wear on the internal surfaces is complicated by the fact that there is a danger of burning the part through and through. Such details include the body of the axle box carriage, which has the following characteristics.

The process of surfacing the axle box body is complex and time-consuming due to the peculiarities of the body design, i.e. the axle box body is a part of a race-type phuba type, with HaiLiaBKe which causes various internal stresses due to uneven metal npoipCBa, the result of which is warpage of the case, change in linear dimensions, rejection. There are many methods for surfacing such parts, but all of them involve the use of specific equipment. who greatly complicated the process and leads to an increase in the cost of this operation. Nanimer, one of the surfacing methods involves pre-heating the part, but for this method it is necessary to have an inductor heater or an electric furnace on the workplace. To avoid these shortcomings, it is necessary to develop a device for the most rational and less than 1 labor-intensive enclosure hull.

The device is a tank (3)., On the bottom of which a centering plate (4) is installed, equipped with clamps for pressing the deposited part (1) to the sealing gasket (6), which protects the inner surface from the ingress of coolant-giving liquid into the surfacing zone. which is stretched over a copper plate (5). The fittings (7) are located at a differently high level so that the cooling LIQUID does not fall into the surfacing zone from above and ensures uniform cooling. The electrode (2) provides surfacing on the inner surface. The cooling rate can be controlled by the temperature of the coolant and its speed.

Claims (1)

A device designed for uniform cooling of thin-walled body parts during surfacing of the worn-out inner surface consists of a tank, two fittings, characterized in that a centering plate is installed on the bottom of the tank for surfacing the inner surfaces of the "thin-walled pipe" parts, equipped with clamps for pressing the deposited part to a sealing gasket that protects the inner surface from the ingress of coolant into the surfacing zone, while the fittings are located at different heights first level so that the coolant does not hit the top cladding region and ensured a uniform cooling.
