Description

In automatic lines, when handing over the processing; 1vaem: x products to measure, you need to preliminarily not only wash them from chips, abrasives, kerosene or emulsions, and also dry the washed products, and washing and drying products should not be done in a line without disrupting the cycle her work. In addition, when there is a short-term transmission after treatment and the control of point products, it is necessary to stabilize their temperature.

Suppose; and products of complex shape with a short residence time in the first 1-s device are made difficult by the fact that in places difficult for supplying drying air there accumulates especially a lot of moisture.

Known for the removal of parts and, whether products by blowing them with compressed air, at the nozzles of the tubes, however, it is uneconomical and does not satisfy the driver of this technology.

The eyuiKH method of parts or products is different from that known in order to improve the drying process, as well as stabilize the bodies: the flow rate of the products being dried and eco-memory in the air flow, the flow of air supplied through flexible tubes with air flow parts of the hardest-to-reach places, and the eyiiJKa enticing device is produced by a stream of air with a stable temperature.

FIG. 1 shows a blowout of compressed parts, such as aluminum orpl1, through flexible tubes; in fig. 2- stroystno d ;; and finished / p-lu eushki parts or products. Air with a stable temperature.

The method is intended for drying after washing in metal products, such as aluminum pistons, and is included in an automatic production line for the production of a single product. The method of drying consists in the fact that for non-drying products, for example, aluminum or aluminum 1, (Fig. 1), it is nill-drying and an oscillating stream of compressed air supplied through soy flexible pipes 2, depending on the shape of the product to be dried.

With this method, the bulk of the moisture is blown off by a stream of compressed air supplied to the product in the most rational way. In addition to blowing off moisture, compressed air produces pre-drying, absorbing moisture.

The final drying and temperature stabilization of the products is carried out with air supplied by the fan 3 from a room with a stable temperature (Fig. 2). For this purpose, a device has been applied, which consists of a fan 3, a chamber for drained products and an air duct 4.

Temperature stabilization is the most crucial operation, since aluminum holes with a linear expansion coefficient, which differs significantly from steel, are transferred after the washing and drying device directly to the control automat, where sorting by hole diameter is performed in 0.0025 mm . Therefore, the temperature of the pistons after stabilization should be constant within the limits of: g 0.5 °.

Subject invention

A method of drying products, such as aluminum pistons, with compressed air, characterized in that, in order to speed up the process of drying products with obtaining a constant temperature of dried products, the compressed air is supplied by a pulsating flow through flexible tubes, the nozzles of which are directed to different places of the products, and the final the latter is dried with air at a stable temperature.
